早产相关因素的临床分析

The Relative Factors of Premature Delivery

目的:探讨早产的主要危险因素,以及早产对围生儿的影响.方法:选取2003年1月～2004年1月于该院分娩的早产者217例作为病例组,并随机选取同期足月分娩产妇200例作为对照组.记录两组产妇相关情况.早产危险因素分析采用Logistic回归,两组围生儿结局比较采用t检验和x2检验.结果:①胎膜早破(PROM)、解脲支原体(UU)和沙眼衣原体(CT)感染、子宫发育畸形、宫颈机能不全、文化程度、产检次数是早产发生的主要危险因素.②两组围生儿体重、窒息发生率、RDS发生率、死亡率差异显著,P＜0.05.结论:早产的发生受多种因素的影响,早产又是新生儿发病和死亡的重要原因.因此,应采取综合预防的措施以减少早产的发生.

Objective： To explore the main risk factors of premature delivery and their effect on the fetus. Methods： 217 patients who delivered prematurely during January of 2003 to January of 2004 were selected as case group. Two hundred women who delivered after the normal period of gestation during the same period were selected as control group. The risk factors of premature delivery were analyzed by Logistic Regression. The outcomes of the two groups were compared by t test and x^2 test. Results： ①The risk factors of premature delivery were PROM, UU and CT infection, uterus malformation, cervical incompetent, education, and the frequency of being examined during pregnancy; ②There was significant difference between the two groups when the fetal weight, Apgar score, RDS incidence, death incidence were compared. Conclusion： Many factors can lead to premature birth, and the latter is the main reason which can cause infant sick and dead. Synthetically measures must be taken to prevent premature delivery.
