对脐动静脉血的酸硷度与血气参数的分析有益于估价胎儿产时状况和分娩处理时的技术.Apgar评分法有助于鉴别正常的和严重受损的新生儿,但鉴别不十分明显的新生儿病变则不够灵敏.因此,最近将脐血pH作为判断产时处理和新生儿结果的有力指标.Wible等也将脐血酸硷度测定应用于围产期的监测和处理.为此,确定这些参数确切的正常值是十分重要的.本文目的是确定脐动静脉血 The analysis of acidity and blood gas parameters of umbilical arteriovenous blood is useful for assessing the timing of childbirth and the technique of childbirth. The Apgar score helps identify normal and severely damaged newborns, but the identification is not very clear Of neonatal lesions are not sensitive enough.Therefore, recently, umbilical cord blood pH as a strong indicator of intrapartum treatment and neonatal outcomes.Wible et al also measure the umbilical cord blood pH for perinatal monitoring and treatment.To this end , It is important to determine the exact normal of these parameters.The purpose of this paper is to determine the umbilical arterial blood
