摘要
目的建立基于生长指标及胎龄推算早产儿经口留置胃管置入长度的公式。方法选择2020年1月至2021年12月生后即收入东南大学附属中大医院新生儿重症监护病房、在入住24 h内因临床需要行经口留置胃管及胸腹部X线检查,并依据检查结果调整置管长度的早产儿进行回顾性研究。记录早产儿置管时胎龄、体重、身长及最终置管长度,以早产儿胎龄、体重及身长为自变量,最终正确置管长度为因变量进行线性回归分析,建立早产儿经口留置胃管长度公式,并与Freeman等的公式进行比较。结果共纳入180例早产儿,胎龄<32周90例,32~35周84例,36周6例。不同胎龄早产儿胃管异位发生率和异位类型差异均无统计学意义(P>0.05);胎龄≤35周的早产儿身长和体重与胃管置入长度呈正相关,胎龄36周的早产儿仅体重与胃管置入长度呈正相关;多元线性回归分析显示,自变量体重或体重和胎龄进入回归方程,回归模型公式分别为经口留置胃管置管长度(cm)=11.8+2.1×体重(kg)或置管长度(cm)=9.5+1.6×体重(kg)+0.091×胎龄(周)。本研究公式与Freeman等的公式比较,随着体重的增加,经口留置胃管长度差异增大。结论早产儿体重和胎龄与胃管置入长度正相关,其中体重的影响最大。
Objective To develop a formula for estimating the insertion length of orogastric(OG)tube for preterm infants based on growth indicators and gestational age(GA).Methods From January 2020 to December 2021,preterm infants admitted to the neonatal intensive care unit of our hospital were retrospectively reviewed.OG tubes were inserted within 24 h of admission and the lengths of OG tubes were adjusted according to chest and abdominal X-ray results.The formula for OG tube placement was developed using stepwise regression analysis method with GA,body weight(BW)and body length(BL)as the independent variables and the corrected length of OG tube as the dependent variable.The weight-based formula developed by Freeman et al.were compared.Results A total of 180 preterm infants were included,with 90 cases GA<32 weeks,84 cases GA 32~35 weeks and 6 cases GA 36 weeks.No significant differences(P>0.05)existed in the incidences of misplacement of OG tube and the specific types of misplacement among GA groups.For infants with GA≤35 weeks,the insertion length of OG tube was positively correlated with BW and BL and for preterm infants with GA 36 weeks,the insertion length of OG tube was positively correlated with BW only.Stepwise regression analysis showed the formula as OG tube length(cm)=11.8+2.1×BW(kg)or OG tube length(cm)=9.5+1.6×BW(kg)+0.091×GA(week).Comparing with the formula developed by Freeman et al.,the differences of OG tube length estimated using our formula were more prominent as BW increased.Conclusions The length of OG tube is positively correlated with BW and GA with BW shows more influence.
