目的 探讨胃管插入长度对新生儿洗胃效果的影响。方法 选取我院2017年3月-2018年3月产科出生的新生儿因吞入 羊水，出现呕吐病例96例作为研究对象，将其随机分为两组，每组48例，即为对照组及观察组。对两组新生儿采用 不同的胃管插入长度，即对照组新生儿胃管插入长度为前额正中发际-剑突。观察组新生儿胃管插入长度为前额正 中发际-肚脐。结果 观察组新生儿的洗胃效果要优于对照组新生儿，且观察组新生儿在洗胃过程中洗胃时间明显短 于对照组，胃粘膜损伤出血率发生低于对照组。结论 采用前额正中发际-肚脐测量胃管插入长度洗胃效果显著，并 且缩短洗胃的时间，减少因反复冲洗对胃粘膜的损伤，有效性和安全性显著，具有临床推广的价值。

Objective To investigate the effect of different insertion length of gastric tube in newborn gastric lavage. Methods 96 newborns born in obstetrics of our hospital from March -2017 to March 2018, who swallowed amniotic fluid and vomited were randomly divided into two groups, each group of 48 cases, as control group and observation group. Different insertion lengths of gastric tube were used in the two groups of newborns, namely, the length of the insertion gastric tube in the control group was in the middle of the foreheads hairline-processus xiphoideus. the length of the insertion gastric tube in the observation group was in the middle of the foreheads hairline-umbilicus. Results The effect of newborn gastric lavage in the observation group was superior to the effect in the control group, and gastric lavage time in the observation group was obviously shorter than that in the control group, and the gastric mucosal injury bleeding rate in the observation group was lower than that in the control group. Conclusion Newborns using gastric lavage length of the middle of the foreheads hairline-umbilicusis has remarkable lavage effects, which can shorten the time of gastric lavage and can reduce gastric mucosal damage by repeated flushing, and can be effective and safety, and have the value of clinical promotion.
