在血液酸碱内稳状态方面,妊娠期母体主要表现为碱血症,即单纯的呼吸性碱中毒倾向;分娩期特别是第二产程又合并代谢性酸中毒,呈现复合型酸碱内稳失常。关于产褥期妇女血液酸碱内稳的变化情况,国外妇女多在麻醉镇痛下分娩,Sj(?)stedt 和Dayal 等分别报告了产褥期妇女血液酸碱状态的复旧过程;而国内妇女通常不采用麻醉镇痛,其产后血液酸碱状态的特点尚未见诸文献。我们选择了无合并症的正常分娩、剖宫产和阴道助产的三组产褥期妇女,进行血液酸碱和气体分析的检测。本文报告113例产褥期妇女在胎盘娩出后24小时血液酸碱和气体分析的结果。
In the blood acid-base stability status, the main manifestation of maternal pregnancy as alkaline blood, that is purely prone to respiratory alkalosis; childbirth, especially the second stage of labor and metabolic acidosis, showing complex acid-base stable disorders . On the changes of blood acid-base stability in puerperal women, foreign women give birth under anesthesia and analgesia, Sj? Stedt and Dayal reported the process of acid-base resumption of the blood in puerperium women respectively. However, domestic women usually do not use anesthesia Analgesia, the characteristics of postpartum blood acid-base status has not been seen in the literature. We selected three groups of puerperium women without complications for normal delivery, cesarean section and vaginal delivery for blood acid and alkali and gas analysis. This paper reports the results of blood acid-base and gas analyzes in 113 postpartum women at 24 hours after the placenta was delivered.
