目的探讨预防新生儿窒息的措施,以降低新生儿窒息的发生率。方法收集我院124例新生儿窒息的临床资料,分析发病的相关高危因素。结果窒息的相关因素依次为:早产因素34例居首位,占27.4%;羊水过少占14.5%;胎位异常占10.5%;产程异常占9.7%;脐带因素(缠绕、脱垂及过短)占8.9%;巨大儿占8.9%;胎盘早剥及前置胎盘占6.5%;妊娠高血压综合征占5.6%;宫内生长迟缓(IUGR)占3.2%。结论加大孕产妇分级管理的力度,加强孕期保健和产前检查,适时纠正臀位,尽量减少早产,及早发现和正确处理胎儿宫内窘迫,是降低新生儿重度窒息的有效措施。 相似文献

Pulmonary effects of closure of patent ductus arteriosus in premature infants with severe respiratory distress syndrome 总被引:1,自引:0,他引:1
The pulmonary effects of closure of a patent ductus arteriosus (PDA) were investigated in 11 premature infants with severe respiratory distress syndrome. Successful closure of a PDA did not improve the short-term severity of pulmonary disease (24 and 48 h after treatment) as judged by the arterial/alveolar oxygen tension ratio or the amount of ventilatory support. Also, pulmonary mechanics measured 24 h before, 24 and 48 h after treatment, were not statistically different.Conclusion Infants with severe respiratory disease requiring high ventilation pressure and high oxygen concentration, where structural changes in the lungs are already established, will rarely show short-term improvement in pulmonary disease as a result of closure of a PDA. The overall clinical condition may, however, improve as a result of reduced cardiovascular strain. Earlier treatment of a PDA could reduce the ventilation period and the possible risk of developing chronic lung disease. 相似文献

Bacteriuria in pregnancy is now easily detected by various techniques adapted to the office setting. It is importtant to screen for bacteriuria in pregnancy because 3%–10% of pregnant women will be positive for occult infection. Up to 30% thus infected will subsequently develop pyelonephritis later in pregnancy, which in turn is associated with premature labor and delivery. This entity must be detected and treated as early as possible in pregnancy to prevent these adverse effects.Presented at the Zambon Symposium on Bacteriuria in Pregnancy, International Urogynecological Association Annual Meeting, Riva del Garda, Italy, September 13, 1989.Dedicated to the memory of Edward H. Kass, MD, PhD. 相似文献

以296例胎膜早破(PROM)作为研究对象,并以350例无PROM作对照,探讨PROM对母婴的影响。结果显示:PROM组难产率为56.08%,产褥病率4.05%,早产率为5.40%,胎儿窘迫率为13.00%,新生儿窒息率为4.33%,新生儿肺炎发生率为3.66%,均明显高于对照组,统计学处理后有显著或极显著性差异(P<0.05,P<0.01)。而且,PROM隐惹期小于24小时的产褥病率为2.29%;大于24小时的产褥病率则为8.97%(P<0.05)。本文提示,应积极预防胎膜早破,一旦出现胎膜早破,宜在6小时内使用抗生素预防感染,并加强母儿监测。 相似文献

In a follow up study of 34 patients with premature adrenarche we examined serum adrenal androgen levels and growth. The majority (28/34) showed an upward bend in the growth curve which, at the mean age of 2.3 years, preceded other signs of adrenarche on average by 3.8 years. Pubertal growth spurt was missing or reduced in 50% of the patients (8/16), however, final height did not differ from that expected from parental heights. Adrenal androgens did not remain elevated at adolescence. The mean age at menarche for all the girls was 0.5 years younger than in the general population.Conclusion Our findings imply that premature adrenarche may start earlier than previously recognized. Compared to ordinary growth these children seen to use a greater part of their potential for adult height already at that early age. 相似文献

双歧杆菌对早产儿食道pH值的影响及临床意义 总被引:2,自引:0,他引:2
目的为探讨双歧杆菌对早产儿食道pH值的影响,及其对早产儿易发生的消化道疾病的防治意义。方法我们采用便携式24hpH值自动记录仪,对61例早产儿进行了食道pH值的动态监测。结果口服双歧杆菌活菌制剂组的30例早产儿,食道pH值明显高于未服药的对照组,t=2.4093,P<0.05。总pH值<4的时间占总观察时间的百分比显著小于对照组。并且治疗组发生消化道疾患的人数也较对照组少。结论早产儿口服双歧杆菌活菌制剂可以减少胃食道反流等消化道疾病的发生。 相似文献

Objective To discuss the clinical value of fetal fibronectin (fFN) and cervical length in predicting preterm birth. Methods Totally, 511 pregnant women at 22-35 weeks of gestations were enrolled from Dec. 2006 to Dec. 2007 at 4 tertiary hospitals in Beijing, and all with either symptoms or high risk factors of preterm birth, but without preterm premature rupture of membrane or vaginal bleeding. Cervical fFN were determined and cervical length of each subjects were measured by ultrasound. The pregnancy outcomes were compared. Results The sensitivity, specificity and negative predictive value (NPV) of fFN in predicting preterm birth within 7 d were 77.4%, 69.4% and 97. 9%, respectively; and 70.5%, 70.0% and 96.2% for deliveries within 34 weeks. The above figures changed to 54.8%, 66.3%, 95.8% for deliveries within 7 d and 59.1%, 67.2%, 94.6% for those within 34 weeks, respectively, when cervical length ≤3 cm was applied to predict preterm birth. When fFN and cervical length were combined, the sensitivity, specificity and NPV were 51.6%, 87.1%, 96.5% for deliveries within 7 d, and 45.5%, 87.60/00, 94.5% for those within 34 weeks, respectively. Conclusions FFN has higher NPV and specificity than cervical length in predicting preterm birth within 7 d and 34 weeks, and the positive predictive value and specificity can be improved when combined with cervical length. 相似文献
