ObjectiveTo explore the application of propofol combined with midazolam intravenous anesthesia in pediatric upper gastrointestinal endoscopy.MethodsA total of 497 ASA I~II patients who received sedative upper gastrointestinal endoscopy were assigned to a children group (2-14 years) and an adults group (18-65 years).The 2 groups were treated with midazolam (0.02-0.03 mg/kg, iv) and propofol(0.6-0.7 mg/s,iv) with an interval of 3-5 minutes. Enterscopy was inserted at light sleep, relaxing muscles, and disappearance of eyelash relaxation. Combining of pro-endoscopy, reaction to intravenous administration, dose of propofol, reaction to endoscopy, time of returning to consciousness, changes of SpO2, R, HR, and BP, and sedative quality were evaluated.ResultsGood sedation of the 2 groups after intravenous administration was observed. Rate of combining of pro-endoscopy in children was lower (42%) than that in adults(100%). The incidence of restlessness, hyperphasia, temporary decreasing of SpO2, dose of propofol of per kilogram weight, time of returning to consciousness in the children were 82.7%, 17%, 2.4 mg/kg, and (17.5+/-3.2) min, respectively, which were all higher in the adults [9%, 4%, 1.4 mg/kg, and (9.5+/-1.3) min, P<0.01]. HR and BP decreased in the 2 groups, and recovered rapidly after the endoscopy. There was no significant difference between the 2 groups(P>0.05).ConclusionIt is safe and effective to use propofol combined with midazolam intravenous sedation anesthesia in pediatric upper gastrointestinal endoscopy.
