分娩方式对新生儿脑动脉血流指数的影响

The Effect of Different on Cerebral Arteries Blood Flow Index of Newborns

目的:研究自然分娩与剖宫产对正常新生儿和窒息新生儿脑血流指数的影响。方法:应用彩色多普勒超声,分别在产后1小时和48～72小时,测量正常新生儿和窒息新生儿脑动脉血流指数并进行比较。结果:二组产后1小时正常新生儿脑动脉血流指数有差别(P<0.01),窒息新生儿脑动脉血流指数无差别(P>0.01);二组产后48～72小时正常与窒息新生儿脑动脉血流指数比较均无差别,P>0.01。结论:分娩方式对正常新生儿脑动脉血流指数有短暂的生理性差别,但对窒息新生儿脑动脉血流指数无影响。

Objective: To study the influence of cerebal arteries blood flow index in newborns of normal and asphyxia between natural delivery and cesarean section. Methods: By high frequency color Doppler ultrosound the cerebral arteries blood flow index of two groups were measured at two periods : 1 hour and 48-72 hours after delivery. Resulte: There was significant difference in the cerebral blood flow index between two groups of normal newborns one hour after delivery (P<0. 01), and no significant difference between the two groups of asphyxiant newborns (P>0. 01). There was no difference in each group 48-72hs after delivery. Conclusion: There was a transient physiological alteration of the cerebral blood flow index of normal newborns following the different delivery mode, but there was no significant difference in the asphyxiant newborns.
