A 2¾-in order cheapest tadacip erectile dysfunction 60, 18-gauge order 20mg tadacip with mastercard erectile dysfunction frequency age, thin-walled Cournand needle or an 18-gauge Cook needle is briskly advanced through the stab wound until the vein or pelvic bone is encountered. When the femoral vein is entered, a free flow of blood into the syringe is apparent. While the operator holds the needle steady with his left hand, he removes the syringe and inserts a short, flexible tip-fixed core (straight or “floppy J”), Teflon-coated stainless steel guidewire. If it does, the wire should be removed, the syringe reattached, and the needle again slowly withdrawn until a free flow of blood is reestablished. Often, depressing the needle hub (making it more parallel to the vein) and using gentle traction result in a better intraluminal position for the needle tip and facilitate passage of the wire. If the wire still cannot be passed easily, the needle should be withdrawn, and the area should be held for approximately 5 minutes. The appropriate-sized dilator and sheath combination is slipped over the wire; and, with approximately 1 cm of wire protruding from the distal end of the dilator, the entire unit is passed with a twisting motion into the femoral vein. The wire and dilator are removed, and the sheath is ready for introduction of the catheter. The insertion of the second sheath is facilitated by the use of the first as a guide. The Cournand needle or Cook needle should puncture the vein approximately 1 cm cephalad or caudal to the initial site. At least one of the sheaths should have a side arm for delivery of medications into a central vein. Frequently, we use a sheath with a side arm in each femoral vein for administration of drugs and removal of blood samples for plasma levels. Many are so large that multiple sticks are preferable from a hemostasis standpoint. Newer, 8 French, multicatheter sheaths will be more widely used as 3 to 4 French catheters become available. During venous studies, a bolus of 2,500 U of heparin is administered followed by 1,000 U/h, and for arterial sticks and direct left atrial access via transseptal puncture a bolus of 5,000–7,500 U of heparin is used followed by 1,000 to 2,000 U/h. Inadvertent Puncture of the Femoral Artery Directing the needle too laterally (especially at the groin crease, where the artery and vein lie very close together) may result in puncture of the femoral artery. This complication may be handled in several ways: (1) The needle may be withdrawn and pressure put on the site for a minimum of 5 minutes before venous puncture is reattempted. Upper Extremity Approach Catheter insertion from the upper extremity is useful if (a) one or both femoral veins or arteries are inaccessible or unsuitable, (b) many catheters are to be inserted, or (c) catheter passage will be facilitated (e. A tourniquet is applied, and ample-sized superficial veins that course medially are identified for use. Lateral veins are avoided because they tend to join the cephalic vein system, which enters the axillary vein at a right angle that perhaps could not be negotiated with the catheter. However, lateral veins can be used successfully in approximately 50% to 75% of patients. If a superficial vein cannot be identified or entered percutaneously, a standard venous cut down can be used. The median basilic vein is generally superficial to the brachial artery pulsation, and the brachial vein lies deep in the vascular sheath alongside the artery. Some investigators prefer the subclavian or jugular approach, but I believe the arm approach is safer. Inadvertent pneumothorax or carotid artery puncture are known complications of subclavian jugular approaches, respectively. Percutaneous brachial artery puncture or brachial artery cut down are rarely used, but may be helpful when left ventricular access is required and the patient has significant abdominal aortic or femoral disease-limiting access. While transseptal catheterization is an alternative option, left ventricular access may be impossible in the presence of a mechanical mitral valve. The order in which specific catheters are inserted is usually not crucially important. In a patient with left bundle branch block, the first catheter inserted should be passed quickly to the right ventricular apex for pacing because manipulation in the region of the A-V junction can precipitate traumatic right bundle branch block and thus complete heart block. Right Atrium The right atrium can be easily entered from any venous site, although maintenance of good endocardial contact may be difficult when the catheter is passed from the left arm. Further detailed mapping is difficult and less reproducible for single point mapping the absence of a localizing system (Biosense, Webster). Multipolar catheters or “basket” catheters may provide simultaneous data acquisition from multiple sites. However, the anatomic localization of these sites is variable from patient to patient. The left atrium may be approached directly across the atrial septum through an atrial septal defect or patent foramen ovale or, in patients without those natural routes, 13 by transseptal needle puncture. The left atrium may also be approached directly by retrograde catheterization from the left ventricle across the mitral 14 valve. Direct left atrial approaches are mandatory for ablation of left atrial or pulmonary vein foci or isolation of the pulmonary veins (see Chapter 14). Most often, however, for routine diagnostic purposes initial assessment of left atrial activation is approached indirectly by recording from the coronary sinus. This is most easily accomplished from the internal jugular, subclavian, or brachial vein in the antecubital fossa (particularly from the left arm) because the valve of the coronary sinus, which may cover the os, is oriented anterosuperiorly, and a direct approach from the leg is somewhat more difficult, although safer than the jugular or subclavian approaches, since pneumothorax or carotid artery injury cannot occur. Any difficulty may at times be circumvented by formation of a loop in the atrium or by using steerable catheters (Fig. Steerable catheters cost 50% to 500% more than the woven Dacron catheter, so we use it only if the woven Dacron catheter cannot be positioned in the coronary sinus. The left ventricle is opened showing the septum (2, 3, 4), anterolateral free wall (7, 9, 11), superior and posterobasal wall (10, 12), and inferior surface (5, 6, 1, 8). Left atrial pacing, however, is often impractical or impossible from these sites because of the high currents required. Nonetheless, transesophageal pacing has been used, particularly in the pediatric population, in the past to assess antiarrhythmic efficacy in patients with the Wolff–Parkinson–White syndrome (see Chapter 10). Right Ventricle All sites in the right ventricle are accessible from any venous site. The apex is the most easily identified and reproducible anatomic site for stimulation and recording. The entire right side of the intraventricular septum is readily accessible from outflow tract to apex. However, basal sites near the tricuspid ring (inflow tract) and the anterior free wall are accessible but are more difficult to obtain. Deflectable tip catheters, with or without guiding sheaths, may be useful in this instance. Left Ventricle Direct catheterization of the left ventricle has not been a routine part of most electrophysiologic studies because either the retrograde arterial approach or transseptal approach is required. However, complete evaluation of patients with preexcitation syndromes, and particularly recurrent ventricular arrhythmias, often requires access to the left ventricle for both stimulation and recording. This is particularly important for understanding the pathophysiology and ablation of ventricular tachycardia.
Graft demonstrates histiocytes and multinucleated giant cells infiltrating the thickness of the specimen (a discount tadacip express erectile dysfunction viagra not working, d order tadacip now erectile dysfunction 40s, hematoxylin and eosin, 20× magnification; b, c, hematoxylin and eosin, 10× magnification). Preimplantation graft properties did not predict postimplantation biomechanical graft behavior. Human dermal graft displayed more strength and stiffness at the start, but these properties diminished with time. The investigators concluded that in this animal model the dermal graft did not offer more mechanical support than autologous fascia or synthetic mesh. As shown in both animal models and clinical studies, porcine dermis cross-linked grafts induce inconsistent long-term response in different hosts. Some behave more as a resorbable material with degradation and total loss of mechanical strength at the graft site during remodeling, and some behave more as a synthetic implant without any tissue ingrowth. In animal models, we have seen that vaginal site implantation displays different behaviors than abdominal site implantation of prosthetic grafts. Allografts were the first biological mesh type to be introduced to North America in the 1990s. Dermis is the most common tissue due to the size of the graft, which may be obtained. Xenografts quickly gained popularity as a result of its reduced cost, improved availability, and reduced regulatory restrictions. In female pelvic reconstruction, biological grafts consist of three types: autologous grafts, and allograft and xenografts . Autologous grafts consist of fascia lata, dura mater, split-thickness skin grafts, or rectus fascia harvested from the host recipient. The differences observed in graft behaviors are likely a result of the host response, tissue types, and processing methods. Tissue processing can alter the immunogenic and foreign body response to these grafts. Perforation of biological grafts has been shown to be beneficial as it promotes angiogenesis and more rapid host infiltration of fibroblasts for collagen deposition. The porosity of the graft material also seems to reduce seroma formation and the risk of infection. Autologous grafts offer the benefit of avoiding the effects of processing, of graft rejection, and of transmissible infections. Because the patient serves as her own donor, these grafts induce very little foreign body reaction, and there is usually good incorporation of the graft into the native tissue. The harvesting of autologous fascia lata has been described in various pelvic floor reconstructive surgical procedures. With the patient’s leg rotated medially in a dorsal lithotomy position, a 4 cm incision is made between a point 2 cm above the lateral epicondyle and directly superior to the medial aspect of the patella. The vertical fibers of the iliotibial tract and the oblique and horizontal fibers of the dorsal fascia lata are exposed with blunt and sharp dissection. A similar 4 cm incision is made 15–20 cm superior to the previous incision in the line of the lateral epicondyle and greater trochanter. The skin is reapproximated with sutures and the leg is wrapped in an elastic bandage. Leg compression is necessary for hemostasis but may increase the risk of deep venous thrombophlebitis. Procurement from the patient’s own body eliminates the concerns about transmissible infections, but harvesting the tissue may be associated with surgical morbidity. Pain, infection, weakness, and unsatisfactory cosmetic outcomes have all been cited as disadvantages to harvesting autologous grafts. In a retrospective review of 71 patients undergoing either a pubovaginal sling or abdominal sacrocolpopexy using autologous fascia lata, Walter reported one case of a hematoma requiring draining and five cases of incisional cellulitis requiring oral antibiotics. Nineteen percent of patients also reported persistent thigh numbness with a mean follow-up time of 25 months . Since their first use in pelvic reconstruction, the popularity of autologous grafts has been surpassed by the use of other materials as a result of questions regarding the durability of autologous grafts . More recently, a reanalysis of a 5-year data on apical repair with cadaveric fascia lata reported success rates exceeding 90% when a composite score was used to define success [13,14]. This was markedly higher than the 68% success rate at 5 years when only anatomic outcomes were measured. The limitation of this analysis from this randomized controlled trial was that the subjective query of patients 1371 was not blinded nor utilized validated instruments. It has been suggested, from in vitro study, that differences in horizontal or vertical graft orientation significantly affects the graft’s bursting strength. Xenografts and allografts must undergo decellularization and sterilization to prevent antigenic responses and infection. Sterilization methods include freeze-drying, solvent dehydration, and irradiation. Previous studies of biological implants used as slings reported that freeze-dried cadaveric fascia lata demonstrated the most diminished biomechanical properties and intratissue consistency after graft implantation [12,15]. Although cross-links exist in native collagen present in dermal grafts, additional processing increases the amount of collagen cross-links, resulting in supplemental cross-linking. The 3D structure of the collagen mechanically strengthens the matrix and impedes degradation by enzymatic collagenase. The effect of supplemental cross-linking on xenograft behaviors appears to play the largest role on host tissue responses. Even though in vitro studies report generally improved graft resistance to enzymatic degradation to host collagenases with increased collagen cross-links, this has not always correlated to clinical efficacy . Long-term tissue reinforcement to serve host tissue regeneration is a purported benefit of cross-linked biological grafts. Cross-linked biologics in the plastic surgery literature were found to behave more as a permanent synthetic. In both translational animal models and in vivo, supplemental cross-links may have a significantly higher immunologic disadvantage, which may result in graft rejection. In the hernia literature, cross-linked dermal grafts were found to be completely degraded in infected wounds. In vivo, cross-linked porcine dermal can behave more as a permanent foreign body or a synthetic due to its lack of integration into host tissue and likely resultant fibrous encapsulation . Non-cross- linked implants facilitate tissue ingrowth without encapsulation and promote tissue remodeling. The balance between extracellular deposition and scaffold degradation is necessary for effective tissue graft reinforcement during tissue remodeling. While some study investigators have reported deposition of new matrix at the site of biological graft implantation, tissue regeneration within a degrading scaffold can be mimicked by fibrotic scar formation. One of the major limitations of biological graft research is the common animal models used. Most investigations in the female pelvic medicine and reconstructive surgery literature have used the New Zealand white rabbit model. In the general surgical literature, rodents, guinea pigs, or minipigs have been utilized. Tissue responses in different species do not directly compare to humans—especially in the long term.
An endolinear cutter 60 is then introduced and the jaws placed in the gastric hole with the tip pointing at the angle of His purchase tadacip 20 mg on-line erectile dysfunction drugs names. The staple lines are inspected and checked with methylene blue for potential leaks buy tadacip 20mg amex erectile dysfunction treatment stents. The procedure is completed with the creation of a foppy Nissen fundoplication with the remaining fundus. After mobilizing the fun- dus, it is divided and resected using several frings of horitzontally placed cutters with blue loads. Then an articulating cutter, which has been calibrated with a 40 Fr Bougie, is placed vertically along the side of the esophagus and fred, creating a lengthened “neo- esophagus. Solid curved arrow indicates fundoplication Toupet The Toupet operation consists of a posterior partial wrap and is usually reserved for Posterior patients with poor esophageal motility on preoperative manometry, with a positive 24 Partial pH study indicating gastroesophageal refux disease. These patients beneft from a par- Fundoplication tial 270-degree wrap rather than a 360-degree wrap that puts the patient at risk of post- operative failure due to dysphagia. The original Toupet fundoplication was an extensive procedure with mobilization of the preaortic fascia behind the posterior fundus, allowing sliding of the fundus in the retroesophageal window. The right part of the posterior fundus was fxed to the right crura and the left part of the fundus was fxed to the left crura; then both aspects of the wrap were fxed to the ante- rior aspect of the esophagus, producing four lines of sutures of three sutures each, total- ing 12 sutures. Two more stitches incorporated the esophagus, resulting in a wrap fxed with 14 sutures. The problem with the technique is that it transforms a mobile wrap into a wrap fxed to the crura (Fig. It is well known that with belching or vomiting, or simple swallowing, the gastro- esophageal junction has vertical movements that put a wrap under tension. Moreover, the crura have closing and opening mechanisms on respiration that increases tension in the wrap with the risk of breakdown of the repair with time. An elegant solution is presented by the Fekete–Toupet modifed fundoplication (Fig. This consists of closure of the crura behind the esophagus and passage of the posterior fundus behind the esophagus, as with the Nissen fundoplication described Toupet Posterior Partial Fundoplication 85 Fig. However, instead of using a 360-degree wrap, a 180–270-degree wrap is used and sutured selectively to the esophagus, leaving one portion of the esophagus free from any wrap. The basic procedures are identical in all respects to the Nissen fundoplica- tion, with a takedown of short gastric vessels, but only six sutures are used to fx the wrap to the esophagus. Paraesophageal Patient positioning and port placement are the same as Nissen funduplication. The important step is to separate the hernia sac from the pleura and not pull the hernia contents inside the abdo- men, since they will be pulled back to the hernia sac right away. This starts on the right crura, extending superior- anteriorly toward the angle of the His. Then the hernia sac is dissected from the right crura extending toward the chest (Fig. One should be careful not to open the pleura, which will result in a pneumothorax. The anesthesia team should periodically check for breath sounds and peak inspiratory pressure to make sure there is no tension pneumo- thorax. If that is the case the insuffation should be stopped right away and a chest tube should be placed. Dotted line shows the line of excision; X the key of the resection of the hernia sac at the angle of His Paraesophageal Hernia 87 Fig. If the sac is completely resected there, the stomach will be more easily reduced from the chest. The dissection continues on the left crura until the two planes of dissection reach each other. Then the esophagus is dissected posteriorly from both the right and left crura and a penrose drain is placed around the esophagus. At this point all the contents of the her- nia sac should be reduced inside the abdominal cavity. Also if the closure is completely performed posterior to the esophagus, it may result in an angled esophagus. In most instances, we reinforce the closure with a piece of absorbable or biological mesh, cut in a U shape, that can be placed around the esophagus on the crura, and fxed in place with sutures or absorbable tacks. After this step, a Nissen or Toupet fundoplication is performed based on preopera- tive studies. Myotomy for On starting the esophageal myotomy it is essential to visualize the gastroesophageal Achalasia junction. This is achieved by division of the phrenoesophageal membrane, the dissection proceeding from right to left. The inferior aspect of the myotomy should be started just at the junction between the esoph- agus and the stomach, and extend 10–20 mm on the gastric side. A scissor is employed for the myotomy after creating a small groove in the muscular layer of the esophagus to allow its introduction (Fig. By combining a spreading motion between the two layers of the esophagus, and dissec- tion with the scissor just dividing the muscular layer, it is possible to see the white, pale esophageal mucosa bulging between the layers (Fig. Traction on the layers, with electrocautery by the hook, will allow safe division of the fnal muscular layers of the diseased esophageal segment. On completion of the myotomy, the integrity of the mucosa is tested by flling the esophagus with about 300 mL of diluted methylene blue. If a small mucosal perforation is revealed, it is possible to insert a stitch of 3–0 Prolene suture, but it is advisable to add an anterior fundoplication (Dor) to the myotomy as an extra safety measure, and to pre- vent refux postoperatively. Finally, if one believes that measures are needed to prevent postoperative gastroesoph- ageal refux, it is also possible to add a posterior 180–270-degree Toupet fundoplication. Bilateral Truncal Vagotomy Vagotomies Truncal vagotomy is not a diffcult procedure and should take no more than about 20 min. The patient setup and the surgeon’s position between the patient’s legs, with the assistants on each side, are the same as for all approaches to the hiatus. The landmarks are also the same: the avascular aspect of the lesser sac that, once opened, leads to the caudate lobe of the liver, and the right crus of the diaphragm at the left side of the caudate lobe (Fig. The right crus of the diaphragm is grasped by the left grasper in the left hand of the surgeon, and the harmonic shears are used to create a small space between the esopha- gus and the right crus. With spreading movements of both the shears and the grasper, the space is enlarged, leading to visualization of the left crus of the diaphragm. If the left crus is not immediately recognized, it is possible to follow the right crus down until it connects with the left crus. It usually lies on the back wall of the esophagus, or next to either the right or left crus. The posterior vagus nerve is a big trunk that cannot be missed: it is white, with small veins running on its surface, and it is elastic and resistant to pulling.

Caffeine Reduction Caffeinated beverages in particular can exacerbate incontinence because in addition to its diuretic effect order tadacip 20mg with amex erectile dysfunction when pills don work, caffeine is a bladder irritant for many people buy discount tadacip 20mg on line erectile dysfunction 20 years old. Research has demonstrated that caffeine increases detrusor pressure  and that it is a risk factor for detrusor instability [59,60]. Evidence also exists that reducing caffeine intake helps to reduce episodes of incontinence [61–63]. Although it is very difficult for most coffee drinkers to completely eliminate it from their diet, provided with the knowledge that caffeine may be aggravating their incontinence, many will be willing to reduce their intake or to eliminate it for a few days as a trial. Reducing caffeine intake can be done gradually by mixing decaffeinated beverages with caffeinated beverages in increasing increments. For example, coffees can be mixed to consist of ¼ decaffeinated coffee in week 1, ½ in week 2, ¾ in week 3, and full decaffeinated coffee in week 4. Avoiding Bladder Irritants Many clinicians recommend, even as a first-line approach, restricting certain foods and beverages that are believed to irritate the bladder, including sugar substitutes, citrus fruits, spicy foods, and tomato products. Although there is little scientific evidence on dietary factors, there are many cases in which these substances appear to be aggravating incontinence, and reducing or eliminating them has provided clinical improvement. A diary of food and beverage intake can sometimes be useful in identifying which substances are irritants for individual patients. Rather than recommending that all patients restrict their intake of these substances, a diary or trial restriction can help to identify which patients are sensitive and may chose to reduce their intake. Women with higher body mass index are not only more likely to develop incontinence, but they also tend to have more severe incontinence than women with lower body mass index. Research on the relationship between body mass index and incontinence reports that each five-unit increase in body mass index increases the risk of daily incontinence by approximately 60% [64,65]. Intervention studies of morbidly obese women report significant improvement in symptoms of incontinence with weight loss of 45–50 kg following bariatric surgery [66–68]. Similarly, significant improvements in continence status have been demonstrated with as little as 5% weight reduction in more traditional weight loss programs . Both groups received a booklet describing a step-by-step self-administered behavioral program to reduce incontinence. The weight loss program, which resulted in a mean weight loss of 8%, showed significantly greater reductions in number of incontinence episodes compared to the control group, which had a mean weight loss of 1. Because moderate weigh loss is an achievable goal for many women, it is rationale to recommend weight loss as a first-line treatment or as part of a comprehensive program to treat incontinence in overweight and obese women. Bowel Management Fecal impaction and constipation have been cited as factors contributing to urinary incontinence in women, particularly in nursing home populations . In severe cases, fecal impaction can be an irritating factor in overactive bladder or obstruct normal voiding, causing incomplete bladder emptying and overflow incontinence. Disimpaction relieves symptoms for some patients, but it can recur in the absence of a bowel management program. Bowel management may consist of recommendations for a normal fluid intake and dietary fiber (or supplements) to maintain normal stool consistency and regular 650 bowel movements. When hydration and fiber are not enough, stool softeners or enemas may be used to stimulate a regular daily bowel movement, preferably after a regular meal such as breakfast to take advantage of postprandial motility. This reliance on patient behavioral change is perhaps the main limitation of this treatment approach. Like any new habit or skill, changing daily bladder habits and learning new skills require effort and persistence over time. It can be challenging for women to remember to use their muscles strategically in daily life as well as to maintain a regular exercise regimen for strength and skill. This gradual change makes it difficult for patients to appreciate even steady improvement over time and represents the primary challenge for behavioral treatment—how to sustain the patient’s motivation for a long enough time that she will experience noticeable change in her bladder control. A key ingredient in addressing this challenge is to maintain contact with the patient during this period of time when her benefit is not yet appreciable. Rather than leaving the patient on her own, it is essential that clinicians support the patient’s efforts to persist by scheduling follow-up appointments to review and reinforce her progress, encourage persistence, identify and address barriers, and make any needed adjustments to her daily regimen. In addition, when initiating behavioral treatment, it is important to make it clear to the patient that her improvement, as with any new skill, will likely be gradual, with good days and bad days, and that it will depend on her consistent practice. The patient who expects this course of treatment will be better prepared to persist over time so that results can be achieved and maintained long term. Little research has examined the durability of behavioral treatments in the long term, but studies are promising in that many patients are able to sustain improvements in bladder control over time [72–74]. Most patients who engage actively with behavioral treatment for incontinence experience some degree of improvement, yet there is considerable variation in outcomes. Little is known to help us predict which patients will respond best to behavioral treatment. Most studies examining predictors of success have found that outcomes are not related to the type of incontinence or urodynamic diagnosis [13,52,55,75,76]. Some studies show that patients with more severe incontinence have greater improvements [52,72], but others conclude that patients with more severe incontinence have poorer outcomes [22,72,76] or no relationship between severity and outcome [24,55,75,77]. Current evidence indicates that outcomes are not associated with patient race, parity, body mass index, cystocele, uterine prolapse, hysterectomy, hormone therapy, use of diuretics, or urodynamic parameters . There is little information in the usual clinical evaluation of a patient with incontinence that would indicate the likelihood of her success or failure with behavioral treatment. Thus, given that behavioral therapies are virtually without risk and most adherent patients experience symptom improvement, offering behavioral treatment as first-line therapy is appropriate for any woman with urinary incontinence.

This results in increasing amounts of nitrogen dissolving in the blood and accumulating in the lipid component of tis- sues cheap tadacip 20mg with visa erectile dysfunction statin drugs. During ascent buy tadacip 20 mg low cost erectile dysfunction latest treatment, as the surrounding pressure decreases, nitrogen is released from the tissues back into the blood and from there to the alveoli where it returns to its gaseous form and can participate in respiration. Too rapid an ascent, as predicted by Henry’s law, will allow dissolved nitrogen to come out of solution and return to its gaseous form whilst still in the tissues or blood. This allows for the formation of gas bubbles which form the pathophysiological basis of decompression illness. As cabin pressure decreases, subclinical microbubbles can expand, as predicted by Boyle’s law, disrupting cells and cellular function if located within the tissues and potentially leading to embolisa- tion if within the blood. It is for this reason that there are defned “no-fy” periods after scuba diving and why patients with decompression illness requiring aeromedical transportation should always be fown at the lowest possible cabin altitude . A review of the literature indicated that no adverse events had been reported during the transport of decompression illness patients if fown at an altitude below 500 ft . The effects of changes in gas volume can also impact any medical device with a pneumatic component. Examples include: Air-flled splints Vacuum mattresses Transport ventilators Intravenous fuid administration sets Endotracheal tube cuffs Drainage bags Plaster casts This can be illustrated by considering endotracheal tube cuffs and transport ven- tilators. An endotracheal tube cuff, being flled with air, can expand on ascent, resulting in increased pressure on the tracheal wall, or contract on descent, increas- ing the risk of aspiration. One study on endotracheal tube intracuff pressure in 114 patients during helicopter transport showed that with a mean increase in altitude of 2,260 ft, 72% of patients had an intracuff pressure >50 cm H20 and 20% were >80 cm H2O. This effect can be overcome by carefully monitoring intracuff pres- sures, especially during the ascent/descent phases of a fight . Transport ventilators have different design characteristics resulting in some older or less sophisticated models altering their performance at altitude. For example, the Drager Oxylog 1000 has pneumatic logic controls which require a change in gas pressure to trigger a cycle from inspiration to expiration. As altitude increases a larger volume of gas is required to trigger this switch resulting in the delivery of a larger tidal volume than has been set. More sophisticated ventilators can have a range of pressure sensors and elec- tronic controls to allow for full compensation of any barometric induced change. This is not usually a signifcant issue in most fxed-wing aircraft as there is varying capacity to control the cabin temperature. The greatest fexibility in this regard is when working in a dedicated air ambulance. When transporting a patient on a commercial fight, remember that they have to cater to a wide variety of passengers, with cabin temperature usually set at ~22 +/−2 °C. Most modern commercial aircraft can, however, adjust the temperature across multiple zones allowing for the option to liaise with the crew to try and better optimise the ambient temperature to a patient’s needs. The A380, for example, can set cabin tem- perature between 18 and 30 °C across 15 different temperature control zones . Ramin Temperature control can be harder to achieve in rotary-wing airframes and the capacity to do so is very much dependent on the specifc platform utilised and the environment in which it is operating. Rotary-wing aircraft can expose both patients and crew to signifcant variations in temperature. In cold weather, this can lead to heat loss, especially in children or the critically ill patient. Conversely, in hot cli- mates, rotary-wing aircraft can behave like a greenhouse, increasing cabin tempera- ture signifcantly even at altitude. Whilst it is important to maintain the thermal integrity of patients during aero- medical transportation, it is important to note that thermal stress can also adversely impact the transport team. Excess heat stress, both hot and cold, can lead to fatigue, decreased attention span, impaired judgement, impaired calculation and poor deci- sion-making, all of which in turn can adversely affect patient care . It is unlikely that many aeromedical services are able to maintain their medications at the correct temperature at all times. Whether the typical fuctuations in temperature that might be encountered in the aviation environment alter medication potency is generally not known. However, it is important to consider the thermal environment in which these operations will occur and to develop storage solutions to maintain as optimal thermal integrity of medications as possible. Relative humidity is predominantly a function of temperature and it decreases as the temperature falls. With increasing altitude, there is a progressive fall in temperature and so the relative humidity will also fall. This, however, cannot be maintained in aircraft as it would lead to condensation and corrosion and so relative humidity is typically kept in the range of 10–20%. Generally, the longer the fight time, the lower the average relative humidity will be during that fight. Prolonged exposure over 3 h or more to this level of relative humidity can lead to drying of the skin and mucosal membranes, which can lead to complications such as sore eyes, sore throat, a dry cough, and epistaxis . However, there is no defnitive evidence that this level of humidity results in any signifcant adverse health outcomes in the average passenger. It has also been suggested that breathing dry cabin air leads to an increased number of respiratory tract infections but there is no objective evidence to support this assertion. Despite this, it is appropriate to monitor a patient’s hydration status, humidify supplemental oxygen where possible, and protect the corneas from drying out in the patient with altered consciousness. Gravity is an accelerative force acting on objects to change their velocity over unit time. A negative vertical G force would act in the opposite direction of gravity [3, 4]. Furthermore, Newton’s third law of motion states that for every action, there is an equal and opposite reaction. When an object accelerates or decelerates in one direction, there will therefore be an equal force applied in the opposite direction, referred to as an inertial force. In relation to G forces and Newton’s third law, the most signifcant impact of fight is on the circulatory system. Consider a patient lying on a stretcher with their head to the front of a fxed-wing aircraft. As the air- craft accelerates for take-off, the patient will be exposed to positive G forces. This will result in the inertial force acting in the opposite direction, increasing blood fow away from the brain and towards the feet. The physiological response to these forces will depend on their direction, duration, and intensity. Positive G forces, which increase blood fow away from the brain, are bet- ter tolerated than negative G forces, which increase blood fow into the brain . Healthy individuals can compensate for short-term changes in blood fow, but there may be potentially adverse consequences in the critically ill patient with haemody- namic and/or neurological compromise. For example, venous pooling in the legs may exacerbate hypotension in the haemodynamically-compromised patient with conditions such as sepsis or blood loss, and lead to a decrease in cerebral perfusion. Conversely, increased blood fow to the brain may lead to an increase in intracranial pressure, which may be clinically signifcant in neurologically compromised patients, such as those with head injury.
