目的：探讨挤压脐带的胎盘输血方法对极低出生体质量(VLBW)早产儿的影响。方法以2011年9月至2014年5月出生并行挤压脐带的57例VLBW早产儿作为挤压组，2008年1月至2011年8月出生并行常规脐带结扎的61例VLBW早产儿作为对照组，分析两组VLBW早产儿常见并发症发生率以及输血情况、肺泡表面活性物质(PS)使用、呼吸机使用时间、吸氧时间和病死率的差异。结果挤压组的重度窒息、侧脑室出血及贫血的发生率低于对照组，差异有统计学意义(P<0.05)；挤压组的输血次数、输血量和机械通气时间明显少于对照组，差异有统计学意义(P<0.05)。结论VLBW出生时行脐带挤压能减轻窒息、减少脑室出血及贫血，并能降低其对输血、机械通气的需求。%ObjectiveTo study the effects of placental transfusion of umbilical cord milking on very low birth weight (VLBW) infants. Methods Fifty-seven VLBW infants born from September 2011 to May 2014 who had umbilical cord milking at birth were selected as experimental group. Sixty-one VLBW infants born from January 2008 to August 2011 who had normal cord clamping at birth were selected as control group. The complications of VLBW infants, blood transfusion, frequency of using pulmonary surfactant (PS), the duration of mechanical ventilation, the duration of oxygen and mortality were compared between two groups.Results The incidence of severe asphyxia, IVH and anemia was signiifcantly lower in experimental group than in control group (P< 0.05). The blood transfusion and transfusion volume, duration of mechanical ventilation, and duration of oxy-gen were signiifcantly lower in experimental group than in control group (P< 0.05).Conclusions Umbilical cord milking can reduce the incidence of severe asphyxia, IVH and anemia. It also can reduce the blood transfusion, the duration of mechanical ventilation, and the duration of oxygen in VLBW infants.
