30 parturient women were randomized into a group receiving paracervical block (PCB) and a control group. The infants were tested by a neurobehavioral examination immediately after birth, after 3 hours and 3 days. The examiner was unaware of the obstetrical management of the patients. No clinically significant differences could be detected between the two groups. Arterial and venous pO2, pCO2 and pH from the umbilical cord showed no differences between the groups.
30名产妇被随机分为接受宫颈旁阻滞（PCB）的组和对照组。婴儿在出生后、3小时后和3天时通过神经行为检查进行测试。检查者不知道患者的产科处理情况。两组之间未检测到临床上的显著差异。两组脐带的动脉和静脉血氧分压（pO2）、二氧化碳分压（pCO2）和pH值无差异。
