Less discomfort and pain when air was, as usually insuflated, as compared with patients receiving intramuscular diazepam. Doctor's opinion coincided with the before mentioned preference for sublingual lorazepam prescribed at least 90 minutes before the endoscopic procedure. No adverse side effects were pointed out.
