Perioperative care of patients undergoing bariatric surgery.

The epidemic of obesity in developed countries has resulted in patients with extreme (class III) obesity undergoing the full breadth of medical and surgical procedures. The popularity of bariatric surgery in the treatment of extreme obesity has raised awareness of the unique considerations in the care of this patient population. Minimizing the risk of perioperative complications that contribute to morbidity and mortality requires input from several clinical disciplines and begins with the preoperative assessment of the patient. Airway management, intravenous fluid administration, physiologic responses to pneumoperitoneum during laparoscopic procedures, and the risk of thrombotic complications and peripheral nerve injuries in extremely obese patients are among the factors that present special intraoperative challenges that affect postoperative recovery of the bariatric patient. Early recognition of perioperative complications and education of the patient regarding postoperative issues, including nutrition and vitamin supplementation therapy, can improve patient outcomes. A suitable physical environment and appropriate nursing and dietetic support provide a safe and dignified hospital experience. This article reviews the multidisciplinary management of extremely obese patients who undergo bariatric surgery at the Mayo Clinic.

Tongue engorgement with prolonged use of the esophageal-tracheal Combitube.

We report a case of massive tongue engorgement associated with placement of an esophageal-tracheal twin-lumen airway device (Combitube) in a morbidly obese patient. Approximately 4 hours after atraumatic placement of the Combitube, tongue swelling occurred. An emergency tracheostomy was needed for airway management before removal of the Combitube. Ischemia-reperfusion injury or compression of glossal blood vessels, specifically lingual veins, was the most likely cause for the patient's tongue engorgement. An exhaustive search for other causes revealed nothing. Prolonged use of the Combitube may incur greater risk of airway complications such as tongue engorgement.

Is physician anesthesia cost-effective?

UNLABELLED: One of the most controversial issues in anesthesia is whether nonmedically directed nurse anesthetists are relatively more cost-effective than anesthesiologists in the provision of anesthesia care. We electronically surveyed anesthesia practices throughout the United States to estimate the range in anesthesia professional costs from the payer perspective. Using this survey data on anesthesia reimbursement and published outcomes studies, we developed an ad hoc model to estimate the cost-effectiveness of physician-directed anesthesia relative to a nonmedically directed nurse anesthetist model of care from the payer perspective. Cost-effectiveness ratios were defined as the ratio of incremental costs associated with physician anesthesia relative to the estimated incremental life expectancy gains with this model of care (i.e., dollars per year of life saved [US dollars /YLS]). Reference case results suggest that physician anesthesia is cost saving with an estimated incremental cost-effectiveness ratio of -US dollars 2601/YLS for a younger privately insured patient and an estimated cost-effectiveness ratio of -US dollars 4410/YLS for an elderly Medicare insured patient. Cost-effectiveness ratios ranged from -US dollars 4410 to US dollars 38778/YLS in univariate and multivariate sensitivity analyses across payer types. Results were most sensitive to assumed differences in reimbursement (commercial conversion factors) and to mortality rate assumptions by provider type. This analysis offers economic evidence in support of the physician anesthesia model of care. IMPLICATIONS: Recent outcome studies suggest improved patient outcomes when physicians medically direct nurse anesthetists versus anesthesia care delivered with nonmedically directed nurses. The relative cost-effectiveness of this practice model is, however, unknown. This economic analysis suggests that outcome gains with physician anesthesia may be obtained at cost savings or, under conservative assumptions, at a cost deemed reasonable by society.
