丙泊酚与硫喷妥钠对电抽搐治疗时抽搐发作的影响比较

A Comparison of the Effects of Propofol and Thiopental on Convulsive Seizure During Electro-convulsive Therapy

目的探讨丙泊酚与硫喷妥钠对电抽搐治疗时抽搐发作影响特点的差异性,为改良式电抽搐疗法中静脉用麻醉药物的选择提供依据。方法对2005年7月至2005年12月在攀枝花市第三人民医院接受电抽搐治疗的111例精神病患者(硫喷妥钠组62例,丙泊酚组49例)进行同顾性分析。两组患者分别在硫喷妥钠和丙泊酚复合琥珀胆碱静脉麻醉下实施电抽搐治疗。对两组患者在治疗中痉挛发作情况进行分析。结果两组患者的主要人口学资料、病种及电治疗参数的差异均无统计学意义(P>0．05),丙泊酚组患者的运动性发作时间和脑电发放时间均较硫喷妥钠组长,其差异有统计学意义(P<0．01)。结论硫喷妥钠可上调大脑皮质神经元的兴奋阈值,降低电抽搐治疗时的痉挛发作程度。丙泊酚可能会使兴奋阈值下调,相同治疗参数引起的痉挛发作较好,但丙泊酚有诱发癫痫样发作的可能。

Objective To explore the effects of propofol and thiopental sodium injection on convulsive seizure in electro-convulsive therapy （ECT） and to provide evidence to help the selection of intravenous anaesthetics in improved ECT. Methods Total of 111 patients who received ECT in the 3rd Pepole＇s Hospital of Panzhihua from July to December 2005 were divided into a thiopental sodium group （n 62） and a propofol group （n -49）. These patients received intravenous anaesthesia with suxamethonium plus thiopental sodium or propofol for the implementation of ECT, respectively. The status of convulsive seizure was compared between the two groups. Results There were no significant differences between the two groups in terms of main demographic data, disease category and ECT parameters （P〉0.05）. Motor seizure and electricity discharge lasted significantly longer in the propofol group than in the thiopental sodium group （P〈0.01）. Conclusion Thiopental sodium can increase the excitation threshold of brain cortical neurons and decrease the level of convulsive seizure induced by ECT. Propofol may decrease the excitation threshold, and increase the level of convulsive seizure under the same ECT parameters, but may have the potential to induce epileptic seizure.
