A small, but significant, number of patients undergoing bariatric surgery refuse blood transfusion for religious or other personal reasons. Jehovah's Witnesses number more than 1 million members in the United States alone. The reported rates of hemorrhage vary from .5% to 4% after bariatric surgery, with transfusion required in one half of these cases. Pharmacologic prophylaxis against venous thromboembolism could further increase the perioperative bleeding risk. Our objective was to report the perioperative outcomes of bariatric surgery who refuse blood transfusion at a bariatric center of excellence, private practice in the United States. ⋯ Bariatric surgery can be performed in patients who refuse blood transfusion with acceptable postoperative morbidity. Larger studies are necessary to confirm the safety of this approach and to examine the effect of pharmacologic thromboprophylaxis in this patient group.

Predictors of a difficult intubation in the bariatric patient: does preoperative body mass index matter?
The incidence of difficult intubations in morbidly obese patients has been reported to be 12-20%; however, no well-established predictors of a difficult intubation exist for this patient population. Our objective was to evaluate the factors associated with a difficult intubation in morbidly obese patients undergoing laparoscopic Roux-en-Y gastric bypass at an integrated multispecialty health system with a 325-bed community teaching hospital serving 19 counties. ⋯ An increased Mallampati class, abnormal thyromental distance, restricted jaw mobility, and a history of difficult intubations were independent predictors of a difficult intubation. An increasing body mass index did not predict for a difficult intubation.
