Geriatric transplant anaesthesia

The elderly comprise a growing fraction of the population with increasing demand for transplant services. Presently, 21% of subjects registered on the organ transplant list are older than 65 and around 18% of all transplants are carried out in the elderly. Despite the increased acceptability of transplantation in the elderly, aged patients still pose greater challenges due to decreased physiological reserve, frailty, and coexisting disease. Indications and outcome of organ transplantation in the elderly differ from the young. Transplantation success depends on careful evaluation and patient selection with optimal perioperative management. The anaesthesiologist has a unique role in the success of transplant surgery by contributing to preoperative assessment and intraoperative and postoperative care. This chapter addresses the physiological changes, outcome, and perianaesthetic management of the elderly transplant recipient, with emphasis on liver, kidney, and multivisceral transplantation

Anaesthetic management of a parturient with spondylothoracic dysostosis

Spondylothoracic dysostosis is a rare congenital disorder characterised by multiple vertebral malformations, shortening of the spine and fusion of the ribs at the costovertebral junction. These abnormalities create anaesthetic challenges due to difficult airway, severe restrictive lung disease and spine deformity necessitating a multidisciplinary approach and careful perioperative planning. We present the perianaesthetic management of a parturient with spondylothoracic dysostosis who successfully underwent preterm caesarean delivery under general anaesthesia with awake videolaryngoscopy-assisted tracheal intubation

Survey of anesthesiologists' practices related to steep Trendelenburg positioning in the USA

Steep Trendelenburg during surgery has been associated with many position-related injuries. The American Society of Anesthesiology practice advisory recommends documentation, frequent position checks, avoiding shoulder braces, and limiting abduction of upper extremities to avoid brachial plexopathy. We conducted a web-based survey to assess anesthesiologists' practices, institutional policies, and complications encountered when using steep Trendelenburg. Two thousand fifty randomly selected active members of the American Society of Anesthesiology were invited via email to participate in a 9-item web-based survey. Results are reported as absolute numbers and proportions with 95% confidence interval (CI). Survey response rate was 290 of 2050 (14.1%). 44.6% (95% CI, 38.9-50.3) of the respondents documented anesthesia start and finish, 73.9% (95% CI, 68.8-79) frequently checked positioning during surgery, 30.8% (95% CI, 25.4-36.2) reported using shoulder braces, 66.9% (95% CI, 61.5-72.3) tucked patients' arms to the side, 54.0% (95% CI, 48.2-59.8) limited fluid administration, and more than two-thirds did not limit the duration or inclination angle. Notably, 63/290 (21.7%) reported a complication and only 6/289 (2.1%) had an institutional policy. The most common complication was airway and face edema, second was brachial plexus injury, and third was corneal abrasions. Most institutional policies, when present, focused on limiting duration of steep Trendelenburg and communication with surgical team. Only 1/6 policies required avoiding use of shoulder braces. Based on survey results, practices related to steep Trendelenburg varied among USA anesthesiologists. Differences included protective measures, documentation, positioning techniques, fluid management, and institutional guidelines. The singular commonality found among all respondents was lack of institutional policies. Survey results highlighted the need for institutional policies and more education

Anesthetic Approach for Endoscopic Repair of Acquired Tracheoesophageal Fistula

Tracheoesophageal fistula develops in 5 % to 15 % of patients with esophageal cancer. Metal stent placement can be used for treatment. Stent placement can result in aspiration, hemorrhage, perforation, migration, and pneumonia. Patients may present for medical attention with unanticipated worsening of the fistula and stent displacement requiring special anesthetic care. We discuss the perianesthetic management of a patient with malignant tracheoesophageal fistula and stent migration who presented for endoscopic esophageal stent replacement

Occurrence and outcome of blood-contaminated percutaneous injuries among anesthesia practitioners: a cross-sectional study

Anesthesia practitioners are at risk for percutaneous injuries by blood-contaminated needles and sharp objects that may result in the transmission of human immunodeficiency virus and hepatitis viruses. Reporting these injuries is important for the early prevention and management of blood-borne infections. To investigate the occurrence, reporting, characteristics and outcome of contaminated percutaneous injuries (CPIs) in anesthesia residents, fellows and faculty. A cross-sectional anonymous survey electronically distributed to all 214 anesthesia practitioners at a large academic multihospital-based anesthesia practice in Florida, USA. The overall response rate was 51% (110/214) (60% (50/83) for residents, 50% (8/16) for fellows and 45% (52/115) for anesthesia faculty). Fifty-nine percent (65/110) (95% confidence interval (95% CI): 5068) of participants reported having one or more CPIs during their years of anesthesia practice (residents 42% (95% CI: 2955), fellows 50% and faculty 77% (95% CI: 6688)). The number of CPIs per anesthesia practitioner who answered the survey was 0.58 for residents, 0.75 for fellows and 1.5 for faculty. Within the last 5 years, 35% (95% CI: 2644) of participants had one or more CPIs (39% of residents, 50% of fellows and 29% of faculty). CPIs in the last 5 years in faculty older than 45 years of age were 12% (3/25) compared to 44% (12/27) in faculty younger than 45 years of age.Analyzing data from practitioners who had one CPI revealed that 70% (95% CI: 5585) reported the incident at the time of injury (residents 85%, fellows 100% and faculty 58%). Hollow-bore needles constituted 73.5% (95% CI: 5988) of injuries. As per participants' responses, 17% (18/103) of CPIs received postexposure prophylaxis and there were zero seroconversions. Based on our study results, most anesthesia practitioners will sustain a CPI during their years of practice. Despite some improvements compared to historic figures, the occurrence of CPIs continues to be high and reporting of percutaneous injuries remains suboptimal among anesthesia residents. A fifth of injuries in the perioperative setting is from an infected source and requires postexposure prophylaxis. Although no infections were reported due to CPI exposure in this study, findings underscore the need for more education and interventions to reduce occupational blood exposures in anesthesia practitioners and improve reporting
