艾灸至阴穴矫正常胎位

过去已有大量的临床报导

均认为有一定疗效。然而

在产科临床实践中

发现有些孕妇的胎位异常

不经任何处理

也可自然回转成正常胎位。因此

在艾灸后胎位被矫正的病例中

就可能包含有一部分胎位自然转正的病例。胎位自然回转率究竟有多高

艾灸后的胎位转正病例数中自然转正者约占多少

国内尚未见这方面的报导。为此

我们对艾灸转胎率与胎儿自然回转率作了对比观察

以期进一步说明艾灸至阴穴对矫正胎位的实际价值。对象与方法一、对象凡是妊娠28～32周

无病理情况的臀位孕妇

均列为观察对象。随机将1. A comparative observation between success rate of correcting fetal position by moxibustion and spontaneous conversion rate The purpose of the present study was further to investigate the spo- taneous conversion rate (the rate of spontaneous conversion to cephalic) and evaluate the real value of correctiong fetal abnormal position by Moxi- bustion. For this purpose

482 of patients with breech presentation at 28- 32 weeks' gestation were randomized to either Moxibustion group or con- trol group. Both of them were treated or observed for 7 days. Version by Moxibustion was successful in 188 of 244 patients in one course of trea- tment. Success rate was 77.04%. of 238 control fetuses

123 converted spontaneously to cephalic. Spontaneous conversion rate was 51.68%. There were significant differences betweed these two groups (X

0.01). It indicates that Moxibustin can prompt the version. Both Jiangxi and Shanghai groups found that the fetuses can return to breech presentation after successful version by Moxibustion or spontaneo- usly. Twenty-two of 157 fetuses succeeded in conversion in Moxibustion group returned to breech Presentation. The reversion rate was 14.02%. of 103 fetuses who converted spontaneously to cephalic

21 returned to their original position. The reversion rate was 20.38%. There is no signi- ficant differences between these two groups. Jiangxi group found that 14 of 61 fetuses succeeded in spontaneou con- version in control group returned to breech

but 12 of them converted to cephalic by Moxibustion again. In 49 of 50 patients (6 patients Were not included because of failing to follow up) who persisted as breech presen- rations in control group version was accomplished by Moxibustion. Of 93 fetuses who succeeded in version by Moxibustion

10 fetuses returned to br- eech and then converted to vertex by Moxibustion again. Of 74 fetuses who returned to breech after successful conversion by Moxibustion and failed spontaneous conversion 71 fetuses converted to vertex by Moxibustion again. The success rate was 95.95%. The Present data indicate that a certain number of fetuses with breech presentation can converted spontaneously to cephalic during pregnancy

but not all of such fetuses can converted. Some fetuses succeeded in version may returned to breech prior to the onset of labor. These fetuses who re- turned to their original position and failed spontaneous conversion may obtain a satisfactory correcting effect by Moxibustion again. This tact further demonstrates that a definite effect in correcting fetal position can be produced and the incidence of breech Presentation at delivery can be markedly reduced by Moxibustion to Zhiyin Points.
