摘要
通过对591例28~40周妊娠资料分析,探讨了晚期妊娠胎位的变化。在整个晚期妊娠中,胎位都在变化。第36孕周以后仍有0.38%的头位胎儿转变为非头位,第28孕周时的非头位胎儿有42.24%可维持至足月娠娠分娩,经产妇的非头位娠娠的发生率和胎位变化的频度均高于初产妇。资料表明,从第28孕周以后即应注意对非头位妊娠的纠正。
The data obtained from 591 pregnant women in their third trimester were.anal- ysed. The changes of fetal position were studied. During the third trimester, fetal position was con- stantly changed. By the 36th week, about 0. 38% of cephalic positions were changed to malposi- tion before delivery. Of all malpostions at the 28th week, 49 (42. 24%) remained unchanged until delivery. The incidence of malposition and the frequency of fetal position changes were higher in multiparae than in primparae. The results showed the correcting of malposition should be paid at- tention to from the 28th week on.
