电痉挛治疗时双太阳穴间电阻测量

Impedance measurement across both temples during the treatment of electroconvulsive therapy

目的:给YA-11型ECT机做板式双太阳穴间治疗时设定一个更合理的假负载。方法:选取ECT时引起完全发作的168人次,通过实测与预测电压的测量,计算出治疗机的合理假负载。结果:双太阳穴间电阻抗为(441.4±27.066)欧姆。其中男性平均电阻抗为(443.7±27.300)欧姆,女性平均电阻抗为(439.0±26.600)欧姆,男、女组平均电阻抗差异无统计学意义(P(0.05);男、女组实测电压差异有统计学意义(P(0.05),男、女组预测电压差异有统计学意义(P<0.01);电阻抗与年龄之间差异有统计学意义(P(0.05);年龄组实测电压差异有统计学意义(P<0.01),年龄组预测电压差异有统计学意义(P<0.01)。结论:YA-11型ECT机在做板式双太阳穴间治疗时420欧姆为更合理的假负载。男、女组发作阈值与电阻抗无关;女性、年龄较大者发作阈值较高。

Objective：To establish an optimal dummy for plate bitemporal treatment with ECT machine of YA - 11 type. Methods：During the ECT treatment 168 complete seizures were available, for which the actual and expected voltage were measured so as to calculate the optimal dummy load. Results： Bitemporal impedance was 441.4 ± 27. 066 ohm. By comparison, the mean impedaee of between male and female subject was no significance （ P 〉0.05, male： 443.7 ± 27. 300 ohm, female： 439.0 ±26. 600 ohm） ; however, there were gender significance in both actual voltage （ P 〈 0.05 ） and expected voltage （ P 〈 0.01 ）. The impedance of different age groups showed dissimilarity （P 〈 0.05 ）, so it was with the measurement of both actual voltage （P 〈 0.01 ） and expected voltage （P 〈0.01 ）. Conclusions： A dummy load of 420 ohm may be optimal for plate bitemporal treatment with ECT machine of YA - 11 type; the seizure threshold may be not correlated with impedance; for female and older subject, the seizure threshold appeares to be higher.
