摘　　要：目的探讨护理干预下不同睡眠体位脐动脉血流S/D比值的变化及对妊娠结局的影响。方法将99例妊娠28-42周经多普勒超声检测脐动脉血流S/D比值异常增高的孕妇随机分为干预组和对照组,干预组根据在平卧位、左侧卧位及右侧卧位3个不同体位时的S/D比值,对孕妇睡眠体位进行指导,而对照组未特意嘱咐睡眠体位。结果干预组经指导采取正确睡眠体位后,有39.6%(19/48)的孕妇异常S/D比值降至孕周正常值,明显高于对照组的17.6%(9/51),差异有统计学意义(P<0.05);剖宫产、胎儿宫内生长受限、早产、胎儿窘迫、新生儿窒息、羊水过少、羊水混浊等发生率降低(P<0.05)。结论采取正确的睡眠体位有利于改善脐动脉血流供应,可使异常S/D比值降至孕周正常值范围,降低剖宫产率,减少妊娠并发症,改善围产儿预后。Objective To explore the effect of nursing interventions on the changes of S/D ratio of umbilical artery blood flow with different sleeping postures and pregnancy outcomes. Meth- ods A total of 99 pregnant women with a gestational duration of 28 to 42 weeks, who had abnor- mal S/D ratios in umbilical artery blood flow were randomly divided into intervention group and con- trol group. The intervention group was asked to take different sleeping postures based the different S/D ratios including horizontal posture, left - lateral posture and right - lateral posture while the control group was not told in terms of sleeping postures. Results 39.6 % pregnant women （19/48） in the intervention group had S/I） ratios return to the normal range after proper instructions in sleeping postures, which was higher than the 17.6% （9/51） in the control group. The difference was statistically significant （P 〈 0.05）. The rates d cesarean section, fetal growth restriction, pre- mature delivery, fetal distress, asphxia neonatorum, oligohysramnios, cloudy amniotic fluid in the intervention group were reduced （P 〈 0.05）. Conclusion To take proper sleeping postures may improve umbilical artery blood flow, bring S/D ratio back to the normal range, lower rates of ce- sarean section, reduce pregnancy complications and improve the perinatal infants prognosis.
