摘要
目的探讨不同孕龄新生儿窒息的产科相关因素。方法选择2005年10月至2009年9月4年间分娩的窒息新生儿304例,根据其孕龄分为3组(<34周、≥34周～<37周、≥37周),专人记录每例新生儿的出生情况及有可能危及新生儿安危的各种高危因素。结果随着孕周增加阴道自然分娩率逐渐增加,剖宫产率和阴道助产率逐渐下降,各组之间比较差异有显著性(P<0.05);胎儿窘迫所致的新生儿窒息比例随孕周增加而增加,而母亲产科并发症及内科合并症的比例随孕周增加逐渐下降,各组之间差异有显著性(P<0.01);异常分娩所致的新生儿窒息的比例在各组之间比较差异无显著性(P>0.05);早产儿胎膜早破发生率为22.08%,高于非早产儿的6.61%(P<0.05);因疤痕子宫所致窒息在早产儿和非早产儿中的差异无显著性(P>0.05)。结论早产儿和非早产儿窒息的产科因素不尽相同,临床上应根据这些差别在产前采取相应的防治措施,尽量避免或减少新生儿窒息发生,从而降低新生儿病死率及伤残率。
Objective To investigate the multiple obstetrical factors causing neonatal asphyxia in different gestational age.Methods 304 cases of neonatal asphyxia which were born in our hospital from Oct were analyzed.2005 to Sep.2009.They were divided into 3 groups（〈34 weeks,≥34-37 weeks,≥37 weeks） according to the gestational age.Results As the increase of gestational age,the natural vaginal delivery rate increased gradually,while the rates of cesarean section and vaginal delivery decreased.There was significant differences among these groups（P〈 0.05）.The rate of neonatal asphyxia due to fetal distress increased with the age of gestational,while the mother＇s obstetric complications and medical complications reduced gradually.The differences among the groups were significant（P〈0.01）.There was no significant difference of the rate of neonatal asphyxia due to abnormal birth among these groups（P〉0.05）.The incidence of premature infants with premature rupture of membranes was 22.08%,which was much higher than that of 6.61% in non-premature infants（P〈0.05）.The rates of neonatal asphyxia due to the scar uterus was no difference between the premature and non-premature infants（P〉0.05）.Conclusion The neonatal asphyxia obstetric factors between the premature infants and non-premature infants were not all the same.Prevention and treatment measurements should be taken to avoid or reduce the incidence of neonatal asphyxia and decrease the neonatal mortality and disability basing on the difference factors.
