Abstract |
The effect of single dose clonidine premedication on the vapour requirement for isoflurane induced hypotension in 20 patients undergoing spine surgery was evaluated. The patients given 5 ug/kg of clonidine P.O. at 90 minutes before operation required a mean expired isoflurane concentration of 1.2+/-0.5 vol% to induce hypotension compared with 2.1+/-0.6 vol% in 0.2 mg/kg of diazepam predmedication group(P<0.05). To achieve satisfactory hypotension, six out of ten patients in diazepam premedication group and l out of 10 patients in clondine premedication group are required supplementary infusion of sodium nitroprusside. In conclusion, clonidine premedication is recommended in isoflurane induced hypotensive anesthesia. |
