[Comparative study between midazolam and diazepam in upper gastrointestinal endoscopy premedication].

A prospective study evaluated and compared midazolam versus diazepam in the upper gastrointestinal endoscopy. Patients were excluded if they had experienced any of the following: intolerance to benzodiazepines, pregnancy, alcohol or drug addiction, and weakness chronic disease. Seventy one patients were assigned to two groups: 36 received diazepam (0,15 Mg/Kg. intravenous) and 35 midazolam (0,07 mg/kg.). Patients in the two study group were similar in regard to demographic data (sex, age, and weight). Midazolam resulted in a marked improvement of conscious sedation and the anxiolysis as compared with the group receiving diazepam (p<0.001). Amnesia were significantly more frequent in the midazolam group (total 77,14% and partial 17,14%) compared with diazepam group (total 11,11% and partial 2,77%). The present study show that midazolam improves patient tolerance lo endoscopy compared with diazepam (p<0.001).The selection of patients is very important, no clinically adverse events related to cardiopulmonary changes ocurred in any group.
