The distribution of gas values of umbilical cord blood was studied in an university clinic population during a period of 3 yr. All patients in labor were guided by obstetrical personnel and continuous electronic fetal monitoring (CTG). Microblood analyses were performed on indication of the CTG. The tenth percentile for the total population for umbilical artery blood pH was 7.14 and base excess was -12.7 mmol/l. The tenth percentile for pH in umbilical venous blood was 7.23 and base excess was -10.2 mmol/l. Increase of acidemia was seen in the following order: optimal pregnancy and labor, spontaneous vertex delivery, multiparity, primiparity, instrumental and breech delivery. Percentiles of umbilical cord blood gases could serve as an index for the standard of obstetrical care in addition to perinatal mortality and other measures of perinatal morbidity.
在一所大学诊所的人群中，对3年期间脐带血气体值的分布情况进行了研究。所有分娩患者均由产科人员指导，并进行连续电子胎儿监护（CTG）。根据CTG的指示进行微量血液分析。脐动脉血pH值的总体人群第十百分位数为7.14，碱剩余为-12.7 mmol/L。脐静脉血pH值的第十百分位数为7.23，碱剩余为-10.2 mmol/L。酸血症的增加按以下顺序排列：最佳妊娠和分娩、自然头位分娩、经产妇、初产妇、器械助产和臀位分娩。除围产期死亡率和围产期发病率的其他衡量指标外，脐带血气百分位数可作为产科护理标准的一个指标。
