为了解妊娠高血压综合征（妊高征）的疗效与甲襞微循环变化的关系，对３７例中、重度妊高征者治疗前与治疗后２４、４８、７２ｈ，５、７天及产后３天的甲襞微循环进行连续动态观察。结果提示：中、重度妊高征的羊水污染程度、新生儿并发症与妊高征治疗期间甲襞微循环障碍的改善明显相关。不论何种方法治疗，甲襞微循环障碍明显改善者羊水污染程度均减轻，新生儿并发症发生率降低。因而认为甲襞微循环障碍的改善可作为判断妊高征疗效的重要指标 To understand the relationship between the curative effect of pregnancy-induced hypertension (PIH) and the changes of microcirculation of nailfolds, 37 cases with moderate and severe preeclampsia were treated before and 24, 48, 72h, 5 and 7 days after treatment and after delivery Three days of nailfold microcirculation for continuous dynamic observation. The results suggest that amniotic fluid contamination and neonatal complications in moderate and severe pregnancy-induced hypertension are significantly associated with the improvement of microcirculation of formazan during the treatment of PIH. No matter what method of treatment, nailfold microcirculation significantly improved amniotic fluid contamination were reduced, the incidence of neonatal complications decreased. So that the improvement of nailfold microcirculation can be used as an important indicator to determine the effect of pregnancy induced hypertension
