中文摘要：
目的探讨体位护理对胎粪吸入综合征患儿的干预效果。方法将90倒胎粪吸入综合征（中型）患儿随机分为观察组和对照组各45例，对照组按常规取仰卧位头偏向一侧或侧卧位，观察组进行体位变更护理，即每4小时按仰卧位、左侧卧位、俯卧位、右侧卧位、仰卧位顺序变更。于实施体位护理后1、5、9、13、17h行血气分析、SpO2值检测，观察同时间段患儿的临床表现。结果1h时spO2、PaO2、PaCO2值两组差异无显著性意义（均P〉0.05），在5、9、13、17h时，观察组SpO2、PaO2显著高于对照组，PaCO2显著低于对照组（均P〈0.05），且临床症状的消失时间显著缩短（P〈0.05，P〈0.01）。结论对新生儿胎粪吸入综合征患几行体位变更护理，可有效改善患儿氧合和临床症状。
英文摘要：
Objective To evaluate the influence of change in body position on the therapeutic effects of meconium aspira-tion syndrome （MAS）. Methods Ninety neonates with moderate degree of MAS were randomly divided into a control group（n=45） and an observation group （n=45）. Neonates in the control group received routine nursing care in supine position with their heads tilted to one side, while those in the observation group passively changed body position in ro-tation from supine position, then left lateral, prone, right lateral, and back to supine. Each position stayed for 4. Re-sults of arterial blood gas analysis and pulse oximetry as well as neonates＇ clinical manifestation were noted 1,5,9,13, 17 after delivery of position care. Results There were significant differences in the results of SpO2 ,PaO2 and PaCO2 be-tween the two group 5,9,13 and 17 h after position care （P〈0.05 for all）. And the duration needed for the clinical symptoms to disappear was significantly shorter in the observation group（ P〈0.05, P〈0.01 ）. Conclusion Change in body position of neonates with MAS can improve oxygenation and diminish clinical symptoms.
