About this study

Official title: Propofol Sedation of More Than 200 mg Enables Patients to Drive Home After Outpatient Colonoscopy Including Colorectal Polypectomy

This study examines that the use of >200 mg of propofol sedation enables patients to drive home safely after outpatient colonoscopy.

Read the detailed description

The hospital policy of routine discharge to normal activity 1 hour after propofol mono-sedation for EGD or colonoscopy was approved by the ethics committee of Showa Inan General Hospital in January, 2004 (http://www.sihp.jp). The investigator' s subsequent experience verified the safety of this discharge policy which was reconfirmed in March 2014. Based on these studies, the upper limit of 200 mg was established for those allowed early discharge and driving to home.

This study examines that the use of >200 mg of propofol sedation enables patients to drive home safely 90-120 minutes after outpatient colonoscopy.
