Abstract:
Objective:To compare the effects of induced hypotensions with sevoflurane and nitroprusside on hemodynamics in dogs. Method:Fourteen mongrel dogs were randomly divided into sevoflurane group and nitroprusside group. After experimental preparation,the MAP was decreased to 8kPa and was kept for 30min either with sevoflurane inhalation or with nitroprusside infusion. MAP, HR,CO,CVP,SV and SVR wrer monitored continuously. Result: During induced hypotension, CO in sevoflurane and nitroprusside groups decreased by 30.7% and 21.6% respectively; HR decreased significantly in sevoflurane group, but not in nitroprusside group; SVR in both groups showed reduction, but more pronounced in nitroprusside group. However,after the termination of sevoflurane or nitroprusside, MAP elevated over baseline with the significant increase of SVR,and CO remaining low. Conclusion:As compared with nitroprusside, sevoflurane has inhibitory effect on circulation,yet it is still efficient to induced hypotension.
