目的探讨延迟脐带结扎对足月儿血氧饱和度(SpO_2)、血常规及光疗发生率的影响。方法选取湖南省妇幼保健院产科阴道分娩新生儿200例(2015年7月-2016年9月)进行回顾性研究,其中100例采用延迟脐带结扎方式(延迟组)、100例采用常规脐带结扎(常规组),监测并对比产后不同时间点两组新生儿SpO_2、血红蛋白、铁蛋白、红细胞压积的差异。结果产后1、5 min及10 min,延迟组新生儿的SpO_2水平均高于常规组(P<0.05);产后30 min、产后4 h,延迟组新生儿SpO_2水平与常规组比较差异无统计学意义(P>0.05);产后24 h、48 h及72 h的血红蛋白、红细胞压积水平比较,延迟组新生儿均高于常规组(P<0.05);延迟组产后发生光疗2.00%、贫血发生率1.00%,均显著低于常规组的15.00%、8.00%,两组比较差异具有统计学意义(P<0.05)。讨论延迟脐带结扎有利于提高足月儿SpO_2、血红蛋白、红细胞压积的水平,降低光疗及贫血发生率。
Objective To investigate the effect of delayed umbilical cord ligation on the full-term blood oxygen saturation (SpO_2), blood routine and the incidence of phototherapy. Methods A retrospective study was conducted on 200 neonates with obstetrical vaginal delivery in Hunan Provincial Maternal and Child Health Hospital (July 2015-September 2016). 100 cases were treated with delayed umbilical cord ligation (delayed group) and 100 cases with conventional umbilical cord ligation Routine group). The differences of SpO_2, hemoglobin, ferritin and hematocrit of two groups of newborns at different time points after birth were monitored and compared. Results The levels of SpO_2 in delayed neonates at 1, 5 min and 10 min after birth were significantly higher than those in conventional groups (P <0.05). There was no significant difference in SpO 2 level between neonatal Sprague-Dawley (P> 0.05). The levels of hemoglobin and hematocrit in postnatal 24 h, 48 h and 72 h in delayed group were higher than those in conventional group (P <0.05). Delayed group occurred 2.00% phototherapy and anemia Rate of 1.00%, were significantly lower than the conventional group of 15.00%, 8.00%, the difference between the two groups was statistically significant (P <0.05). Discussion Delayed umbilical cord ligation is conducive to raising full-term children SpO 2, hemoglobin, hematocrit level, reduce the incidence of phototherapy and anemia.
