A comparative study of clonidine versus a combination of diazepam and atropine for premedication in orthopaedic patients.
Sixty patients in the age group of 18-60 years of A.S.A. Grade I/II risk, scheduled for elective orthopaedic surgeries under general anaesthesia were studied for pre-medication with either oral clonidine or with combination of effects of diazepam & atropine. Patients in Group A (clonidine group) received tablet clonidine 100 mcg (1 tablet) if less than 50 kg in weight and 200 mcg if weighing more than 50 kg two hours before surgery. Patients in Group B (Diazepam-atropine group) received one tablet of Diazepam (10 mg) orally two hours before surgery and injection atropine-sulphate 0.01 mg/kg half an hour preoperatively by intramuscular route. In our study, the sedative and anti-sialogogue effects of clonidine were comparable to those of diazepam-atropine combination, which are commonly used premedicants. The anti-anxiety effect of clonidine was found to be better than that of diazepam-atropine combination. Clonidine also proved to be a better agent for the attenuation of pressor response to laryngoscopy and intubation. Thus, oral clonidine is a better premedicant compared to atropine-diazepam combination. Also, it is a more acceptable agent because of its oral route of administration.
