title: Impact of sedation and resident teaching on complications of colonoscopy.
abstract: There is controversy regarding the frequency of sedation-related complications of colonoscopies and whether these procedures are safely performed by physicians-in-training. We retrospectively reviewed the safety of 1,004 consecutive outpatient colonoscopies. No perforations occurred. No patients were hospitalized for sedation-related complications. Seventeen percent of patients had significant changes in vital signs that lasted less than 5 min. These changes were less common in patients receiving </=3 mg midazolam intravenously without meperidine (p < 0.005). Complications were slightly more frequent in procedures performed by trainees (23%) than by gastroenterologists (12%) and by surgeons (18%) (p = 0.01). These data support the safety of colonoscopy under intravenous sedation, even when performed by trainees.
