普鲁卡因静脉复合麻醉与Q-Tc间期延长

Q Tc Interval Prolongation during Intravenous Procaine Combined Anesthesia

观察普鲁卡因静脉复合麻醉期间出现的Ｑ－Ｔｃ间期延长过程。认为Ｑ－Ｔｃ间期时限延长的出现可作为判断普鲁卡因静脉复合麻醉中普鲁卡因血药浓度的参考指标；加大普鲁卡因剂量从而增加血药浓度，其心脏毒性必然相应增加。

30 cases of Q Tc interval prolongation found during intravenous procaine combined anesthesia were analyzed. Authors supposed that its occurance might be correlated with blood concentration of procaine, and be taken as referential signal of cardiac toxicity of procaine.
