本文对303名孕产妇进行了 A 型行为问卷测验并调查了孕产妇分娩时顺产、难产及分娩期并发症等有关情况。对 A 型行为孕产妇和 B 型孕产妇的分娩情况进行比较以探讨心理因素对分娩的影响。结果表明:A 型组难产和分娩期并发症明显多于 B 型组,两组间有显著性差异 P<0.05);另外产后平均出血量也明显多于 B 型组,差异显著(P<0.05)。其机理可能是由于应激产生精神过度紧张通过下丘脑—交感肾上腺轴和下丘脑—垂体—肾上腺轴的过度兴奋导致激素、儿茶酚胺分泌异常所致。
This paper carried out a type A behavioral questionnaire test for 303 pregnant women and investigated the status of maternal complications of obstetric delivery during labor, labor and childbirth. A type of behavior of pregnant women and B-type delivery situation were compared to explore the psychological factors of childbirth. The results showed that the complications in type A group were more than those in type B group, there was a significant difference between the two groups (P <0.05); meanwhile, the average postpartum hemorrhage volume was significantly more than that in type B group (P <0.05 ). The mechanism may be due to stress-induced mental stress caused by abnormal secretion of hormones and catecholamines through hypothalamic-sympathetic adrenal axis and hypothalamic-pituitary-adrenal axis over-excitement.
