观察窒息对新生儿胆囊排空功能的影响。方法用B超检测窒息新生儿107例及正常对照组新生儿219例胆囊排空前后胆囊的长径、直径，计算出胆囊排空前后最大纵断面积近似值(长径×直径)的均数、各指标胆囊排空前后差值及胆囊排空率；并用统计学方法比较以上各指标。结果窒息组的各差值及胆囊排空率均小于正常对照组，而最大纵断面积近似值却大于正常对照组(P均＜0.01)。结论窒息可使新生儿胆囊排空功能明显减弱，使新生儿胆囊扩张。%Objective To observe the influence of asphyxia on gallbladderemptying in neonates. Methods The lengths and the diameters before and after the gallbladder emptying were measured with B-ultrasonoscope on the asphyxia group(107 cases) and the normal group (219 cases). The approximate area values of the largest gallbladder vertical section before and after gallbladder emptying were calculated (the length times the diameter). The differences rates of gallbladder emptying were also counted. Then, all the above-mentioned values were compared statistically between the asphyxia group and the normal group. Results The differences and the emptying rates of the newborns with asphyxia were less than that of the normal newborns, while the approximate area values of the largest gallbladder vertical section were larger than that of the normal ones (P＜0.01). Conclusions Asphyxia can reduce the emptying function of the gallbladder and make the gallbladder enlarge.
