Efficacy and safety of propofol sedation during urgent upper gastrointestinal endoscopy--a prospective study.

The aim of this study was to investigate both the efficacy and safety of sedation with propofol during urgent therapeutic gastroscopy in patients with upper gastrointestinal bleeding. This prospective study included a total of 110 patients. Propofol was administered intravenously at the starting dose of 1 mg/kg body weight and was followed by repeated doses. Oxygen saturation and heart rate were monitored by pulse oxymetry. The mean dose of propofol administered was 161 +/- 49 mg. Urgent upper GI endoscopy under propofol sedation was successful in 98% of cases. Endoscopists rated the sedation as good in 83.6%, satisfactory in 14.5%, and poor in 1.8% of patients. Potentially harmful drop in oxygen saturation below 85% was observed in 5.5% of patients, whereas a temporary drop in heart rate below 50 beats/min was observed in 11.8%, not requiring any intervention. Almost 93% of patients could not remember the beginning or the end of the intervention. This data demonstrates that sedation with propofol is suitable for use in patients with upper gastrointestinal bleeding undergoing urgent endoscopy.
