When patients in two cases did not receive complete preanesthetic evaluation, problems with intubation ensued. In the first case, an anesthesiologist went to evaluate a morbidly obese patient scheduled for hysteroscopy. As the patient was donning her hospital gown behind a closed curtain, he waited but left without performing the preoperative assessment because the morning surgery list was overbooked and he had many other patients to see. Once in the operating room, he discovered on chart review that the woman had a history of gastroesophageal reflux.
