One year's obstetric experience at Los Angeles County-University of Southern California Medical Center was reviewed and compared with previous years. The incidence of cesarean section for fetal distress is low and has remained constant over the past 7 years. Periodic changes and decreased baseline variability of the fetal heart rate accounted for 39% of the diagnoses of fetal distress in this group. Scalp sampling clarified the diagnosis of fetal distress and prevented unnecessary cesarean section. Compromised perinatal outcome in the greater than 2,500 gram weight group was confined to those who were monitored, had indications for monitoring, or had identifiable prospective risk factors, with rare exceptions.
回顾了在洛杉矶县-南加州大学医学中心一年的产科经验，并与前几年进行了比较。因胎儿窘迫而行剖宫产的发生率较低，且在过去7年中一直保持稳定。该组中，胎儿心率的周期性变化和基线变异性降低占胎儿窘迫诊断的39%。头皮取样明确了胎儿窘迫的诊断，并避免了不必要的剖宫产。体重超过2500克的组中，围产期结局不良仅限于那些接受监测、有监测指征或有可识别的潜在危险因素的情况，极少数情况除外。
