ABSTRACT Anesthetic management of super-obese patients is inferred from evidence which has been based on obese or morbidly obese patients. We present the perioperative management and monitoring of a 44-year-old 232-kg patient (BMI 70) admitted for laparoscopic gastric bypass surgery. Awake fiberoptic endotracheal intubation preceded induction with propofol and rocuronium. Anesthesia was maintained with desflurane and remifentanil. Desflurane was titrated on BIS values, whereas remifentanil was based on hemodynamic monitoring (invasive arterial pressure and HemoSonic). Rocuronium was administered based on ideal body weight and recovery of twitch tension. Safe and rapid extubation in the operating theatre was made possible by the use of short-acting agents coupled with continuous intraoperative monitoring. Recovery in the post-anesthesia care unit was uneventful, pain was managed with meperidine, and after 5 hours the patient was discharged to the surgical ward. Oxygen therapy and SpO2 monitoring were continued overnight. No desaturation episodes were recorded. Pain was managed with I.V. drip of ketorolac and tramadole.

    ABSTRACT: Although the implications for the anesthetic and perioperative care of severely obese patients undergoing weight loss operations are considerable, current anesthetic management of super-obese (SO) patients (BMI > or =50 kg/m(2)), including super-super-obese (BMI > or =60) derives from experience with morbidly obese (MO) patients (BMI 40-49.9 kg/m(2)). We compared anesthetic and perioperative data of SO patients and MO patients undergoing weight loss operations to evaluate if anesthetic management influenced outcome. A retrospective analysis was performed on data from 150 consecutive patients (119 MO, 31 SO) undergoing bariatric surgery between May 2000 and March 2005. Data analyzed included preoperative anesthetic assessment, anesthetic management, postoperative care, and intra- or postoperative complications. There were no differences in anesthetic management or in postoperative course or outcome between MO and SO patients. Intraoperative surgical complications occurred in 26% (n=8) in the SO group and 14% (n=15) in the MO group (P<0.01). No differences in outcome occurred between MO and SO patients undergoing bariatric operations under similar anesthetic management. Anesthesia for weight loss surgery can be safely performed on SO patients with the understanding that these patients are not at risk per se due to their higher BMI. The degree of obesity influenced only the incidence of intraoperative surgical complications.

    ABSTRACT: Severe obesity can be associated with significant alterations in normal cardiopulmonary physiology. The pathophysiologic effects of obesity on a patient's pulmonary function are multiple and complex. The impact of obesity on morbidity and mortality are often underestimated. Bariatric surgery has been shown to be the most effective modality of reliable and durable treatment for severe obesity. Surgical weight loss improves and, in most cases, completely resolves the pulmonary health problems associated with obesity.

    ABSTRACT: To reevaluate and update evidence-based best practice recommendations published in 2004 for anesthetic perioperative care and pain management in weight loss surgery (WLS), we performed a systematic search of English-language literature on anesthetic perioperative care and pain management in WLS published between April 2004 and May 2007 in MEDLINE and the Cochrane Library. We identified relevant abstracts by using key words, retrieved full text articles, and stratified the resulting evidence according to systems used in established evidence-based models. We updated prior evidence-based best practice recommendations based upon interim literature. In instances of controversial or inadequate scientific evidence, the task force reached consensus recommendations following evaluation of the best available information and expert opinion. The search yielded 1,788 abstracts, with 162 potentially relevant titles; 45 were reviewed in detail. Despite more information on perioperative management of patients with obstructive sleep apnea (OSA), evidence to support preoperative testing and treatment or to guide perioperative monitoring is scarce. New evidence on appropriate intraoperative dosing of muscle relaxants allows for greater precision in their use during WLS. A novel application of -2 agonists for perioperative anesthetic care is emerging. Key elements that may enhance patient safety include integration of the latest evidence on WLS, obesity, and collaborative multidisciplinary care into clinical care. However, large gaps remain in the evidence base.
