不同体位对早产儿胃残留量的影响

Effects of different positions on gastric residuals volume in preterm infants

目的:观察不同体位对早产儿胃残留量的影响。方法:选取2019年1月-2020年4月胎龄<34周、体重<2000 g、管饲喂养的早产儿38例,当肠内营养达到100 mL/(kg·d)时,随机确定开始观察的护理体位,每3 h更换1次体位,从仰卧位到俯卧位,或从俯卧位到仰卧位。分别在管饲喂养后30 min、60 min、90 min、120 min、150 min测量胃残留量。结果:无论是仰卧位还是俯卧位,在管饲喂养后30 min内胃残留量下降速率最快;俯卧位管饲喂养后30 min、60 min、90 min、120 min、150 min胃残留量均比仰卧位管饲喂养的胃残留量低,差异有统计学意义(P<0.05)。结论:管饲喂养后的第1个30 min内将早产儿置于俯卧位,然后根据早产儿的状态调整体位,从而为早产儿提供有效护理。

Objective:To observe the effect of different positions on gastric residuals volume of preterm infants.Methods:From January 2019 to April 2020,38 cases of preterm infants with gestational age<34 weeks and weight<2000 g,with tube feeding were enrolled,as enteral nutrition reached 100 mL/(kg·d),the nursing position was randomly determined,changed position every 3 h,from supine position to prone position or from prone position to supine position.Gastric residuals volume were measured 30 min,60 min,90 min,120 min,150 min after tube feeding,respectively.Results:Both supine and prone positions showed the fastest rate of gastric residuals volume decreased within 30 min after tube feeding.Gastric residuals volume of 30 min,60 min,90 min,120 min and 150 min after tube feeding in prone position were lower than those in supine tube feeding,the differences were statistically significant(P<0.05).Conclusion:The preterm infants were placed in prone position within 30 min after tube feeding,then adjusted positions according to the state of preterm infants,so as to provide effective nursing care for preterm infants.
