The anesthetic effects of small dose of midazolam or ketamine used for intemperants′ endoscopy

Abstract

Objective To explore the safe and effective intravenous anesthetic regimen for intemperants′ painless endoscopy. Methods 120 cases of intemperants, aged 25-65 years old, ASA grade Ⅰ or Ⅱ , were randomly divided into 3 groups (n=40): sulfentanyl group (group S), midazolam and sulfentanyl group(group MS), ketamine and sulfentanyl group (group KS). Group S were intravenous injected with sufentanil 0.1 μg/kg, propofol 1-2 mg/kg, etomidate 0.1 mg/kg. Group MS and group KS were additional intravenous injected with midazolam 0.01 mg/kg and ketamine 0.1 mg/kg on the basis of Group S respectively. The occurrence of hypoxia, cough, body movement and blood pressure were recorded, the use of vasoactive drugs and the recovery time were also recorded. Results There are no statistical significant difference of age, gender, and testing time among the three groups (P>0.05). Compared with the group S, the total dose of propofol, the incidence of hypoxemia and hypotension, the incidence of body movement and cough reaction in group MS and group KS were all lower (P 0.05). Conclusions Small doses of midazolam or ketamine combined with sulfentanyl, propofol and etomidate are safe and effective in the process of anesthesia during endoscopic diagnosis and treatment of intemperants.
