The relationship between pulsatility index (PI) in the middle cerebral artery (MCA) and adverse perinatal outcome was studied in 162 normal and 75 high-risk pregnancies. The intrapartum cardiotocographic (CTG) findings, the mode of delivery, 1 and 5-minute Apgar scores, the pH level of the umbilical artery, admission to the neonatal intensive care unit (NICU) and the incidence of intrauterine fetal growth retardation were recorded. In the low risk group, the PI values in the MCA were only affected in growth retarded fetuses (P = 0.0084). In the high-risk group, there was an association between the MCA PI values and 5-minute Apgar scores (P = 0.0397), umbilical artery pH values (P = 0.0068) and development of IUGR (P = 0.0376). In both groups, an abnormal intrapartum CTG, the 1-minute Apgar score, cesarean section for fetal distress and admission to the NICU were not related to PI values in the MCA. Our present study suggests that Doppler flow measurement of MCA provides useful information about perinatal outcome, especially in the high-risk pregnancies.
对162例正常妊娠和75例高危妊娠研究了大脑中动脉（MCA）搏动指数（PI）与围产期不良结局之间的关系。记录了产时胎心监护（CTG）结果、分娩方式、1分钟和5分钟Apgar评分、脐动脉pH值、入住新生儿重症监护病房（NICU）情况以及胎儿宫内生长受限的发生率。在低风险组中，MCA的PI值仅在生长受限胎儿中受到影响（P = 0.0084）。在高危组中，MCA的PI值与5分钟Apgar评分（P = 0.0397）、脐动脉pH值（P = 0.0068）以及胎儿宫内生长受限的发生（P = 0.0376）之间存在关联。在两组中，产时CTG异常、1分钟Apgar评分、因胎儿窘迫行剖宫产以及入住NICU均与MCA的PI值无关。我们目前的研究表明，MCA的多普勒血流测量可为围产期结局提供有用信息，尤其是在高危妊娠中。
