新生儿鼻胃管置管长度测量方法的研究

目的 探讨最合适的体表测量方法,准确测量新生儿鼻胃管置管长度.方法 选取60例放置胃管的患儿,每例患儿均采用"前额正中发际-脐"新体表测量法,"前额正中发际-剑突"常规体表测量法以及实际置管长度的测量,并比较新体表测量法与常规体表测量法所测的置管长度与实际置管长度的差别.结果常规体表测量长度与实际置管长度比较差异有统计学意义,P＜0.01;新体表测量长度则与实际长度差异无统计学意义,P＞0.05.结论 新体表测量法所得的置管长度接近于实际胃管置管长度,更适于新生儿,应大力提倡运用"前额正中发际-脐"的体表测量方法来测定新生儿鼻胃管的置管长度.

Research in length of naso-gastric tube for infants

Objective To accurately measure the length of naso-gastric tube for infants by adopting ap-propriate body surface measurement. Methods We chose 60 infants and adopted two methods to measure the length of tube,one was the new method by which we measured the distance from the middle of hair border of forehead to umbilicus and the other was the traditional method by which we measured the distance to xiphoid process from the same beginning point as the new method.Then we compared the results from the two methods with the actural length of the tube. Results The result of the traditional method was statistically different from the actural length of the tube (P ＜ 0.01 )But the result of the new method was near to the actural length of the tube (P＞ 0.05). Conclusions The result of the new measuring method was near to the actural length of the naso-gastric tube and was suitable to the infants.It reduced the adverse effect caused by the traditional method and improved the effect of diagnosis and treatment greatly.So we advocated to measure the distance from the middle of hair border of forehead to umbilicus as the length of naso-gastric tube.
