祖国医学认为针刺的治疗作用主要在于对机体的调整

针麻剖腹产的临床实践也证明了这一点.因此我们考虑用针麻为中毒症患者行剖腹产术应具有弥补因中毒症病理而致的血管运动机能紊乱

保持术中生理功能的稳定

减少术中出血

于是我们扩大了临床应用范围

逐步把针麻亦列为中毒症剖腹产常规麻醉。今就72～79年6月底八年来所作的部分资料总结如下

并取66～70年在硬Two hundred and ninety-six cases of toxemia of pregnancy under-goingcesarean section under acupunoture anesthesia from 1972 to 1979 were anal-yzed

among which 23.3%(69 cases)was mild

56.4%(167 cases)moderate and 20.3%(60 cases)severe.Before operation all cases had received varioustreatments for toxemia.At the time of operation patient's toxemia conditionwas improved and stationary in 71.4%.METHOD OF ACUPUNCTORE ANESTHESIAPrescription:There were three main prescriptions of acupuncture anest-hesia points:1.Sanyinjiao(Sp.6)

external anesthesia point and para-incision needles.2.Renzhong(Du 26)

Chengjiang(Ren 24)and para-incision needles.3.Sanyinjiao(Sp.6)Taichong(Liv.3)Xiajuxu(St.39)and para-inc-ision needes.The frequency of stimulation

time of induction and supplementarymedication were the same as in ordinary cesarean section under acupunctureanesthesia.EFFECTIVENESS AND CLINICAL OBSERVATIONSThe effective rate was 99%.The combined rate of Grade Ⅰ and GradeⅡ was 71.3%.Blood pressure:Throughout the course of operation the blood pressurewas fairly stable.For example

during the delivery of baby the averagevalues of fluctuation of blood pressure in systolic pressure and diastolic pres-sure were 15.2 mmHg and 9.9 mmHg respectively which were close to thoseof the control group.Pulse Rate:In the whole course of operation the pulse rate was sta-tionary.During delivery of baby the average change was 12.56 time/min

which was close to the 12.1 time/min

in the control group.Amount of Blood Loss:The average amount of blood loss during opera-tion in toxemia and control group were 205.96 ml and 278.3 ml respectively.The blood loss in toxemia group was less than the control group.Postoperative Recovery:The blood pressure began to drop within twodays in 77.5%(200 cases)and returned to normal in 64.7%(167 cases)within three days after operation.The recovery of blood pressure postopera-tively was closely related to the type of toxemia.In mild cases the bloodpressure started to drop and returned to normal earlier.THE COMPARISON BETWEEN ACUPUNCTURE ANESTHESIA ANDEPIDURAL ANESTHESIADuring delivery of baby the fluctuation of blood pressure in acupunctureanesthesia group was less than in epidural anesthesia group.The average bloodloss during operation in acupuncture anesthesia group was less.It is evident that acupuncture anesthesia is a safe and effective anestheticmethod to be used in cesarean section for patients with toxemia of pregnancy.
