高海拔地区足月IUGR98例分析

AN ANALYSIS OF 98 CASES WITH IUGR IN HIGH ALTITUDE

本文通过对１９９３年１月～１９９５年８月足月宫内发育迟缓的９８例病例临床分析，认为高原寒冷、缺或是青海地区低体重儿发生率高的主要原因，因孕妇处于低氧环境可造成胎儿缺氧、宫内发育不良，导致ＩＵＧＲ，而ＩＵＧＲ胎儿处于慢性宫内窘迫状态，新生儿窒息率及围产儿死亡率均高于正常，所以对足月ＩＵＧＲ要认真进行产前监护及恰当的分娩方式，可改善ＩＵＧＲ的预后。

he 98 cases with IUGR(intrauterine growth retardation) during Jan. 1993-Aug. 1995 wereanalysed. It is indicated that the cold and hypoxia of high altitude were responsible to the highrate of low birth weight.Because the pregnant women lived in hypoxic circumstances,thicr fetusexposed to hypoxia too,which led to IUGR,and the fetus fell into chronic fetal distress. The re-sults also showed that the occurrence of asphyxia neonatorum and perinatal mortality were higherthen normal group.So ante partum monitor and correct delivery pattern might improve the prog-nosis of IUGR.
