剖宫产儿的啼哭肺功能研究

STUDY ON CRYING PULMONARY FUNCTION IN NEONATAL BABIES DELIVERED BY CESAREAN SECTION

对79例初生至四天的新生儿作啼哭肺功能动态观察,其中择期剖宫产儿21例、急期剖宫产儿15例、正常阴道产儿43例。结果表明,三组新生儿啼哭肺功能指标均随时龄而增大。但择期剖宫产儿生后数天啼哭肺活量(CVC)、FEV_1、V_(50)及V_(25)低于正常阴道产儿及急期剖宫产儿(P <0.05);而急期剖宫产儿与正常阴道产儿间差异无显著意义(P>0.05)。提示分娩方式对新生儿生后肺功能的影响并不重要,关键是母体规律宫缩的始动与否。

Serial measurements of crying pulmonary function were made during the first 4 days of life in 79 newborn babies, including 21 clinically normal term babies born by elective cesarean section, 15 born by emergency cesarean section and 43 born vaginally. They demonstrated that the mean valves of crying pulmonary function increased with the hours of age in three groups. But clinically normal term babies born by elective cesarean section had a smaller mean CVC, FEV1, V50 and V25, compared with those born vaginally and those born by emergency cesarean section (P<0.05). In contrast, no significant difference was shown between the mean CVC, FEV1, V50 and V25 in terra babies born vaginally and those born by emergency cesarean section. This suggests that influence of ways of delivery. on the neonatal pulmonary function is not important, but the principal problem is whether the labour is at the onset or not.
