探讨三种挤压方法对PTCD管引流效果的随机对照研究

A randomized controlled study of three extrusion methods on the drainage effect of PTCD tube

目的探讨PTCD管的挤压方法,以保持管道引流通畅,促进术后康复。方法选取胆道造影术后放置PTCD管患者120例,按照随机对照单盲原则将患者分为A、B、C三组,每组40例。A组采用快速挤压法;B组采用绕指法;C组采用渐进V形法。结果对三种挤压方法的疼痛率及出血率进行比较,差异均具有统计学意义(P<0.05),其中绕指法疼痛率及出血率最高;三种方法单次挤压次数比较,差异具有统计学意义(F=36.069,P<0.001);三种方法挤压前后通畅率对比,C组挤压前后通畅率差异具有统计学意义(χ^(2)=6.725,P<0.05),提示渐进V形法挤压通畅效果最佳。结论渐进V形法单次挤压次数适中,引流管通畅效果最佳,挤压后疼痛及出血并发症较少,既不影响患者舒适度,又不增加操作者负担,更适合作为PTCD管挤压方法的首选方式。

Objective To explore the squeeze method of PTCD tube to maintain smooth drainage of the tube and promote postoperative recovery.Methods A total of 120 patients with PTCD tube placed after cholangiography were selected,and the patients were divided into three groups A,B,and C according to the randomized controlled single-blind principle,with 40 cases in each group.Group A adopts the rapid squeeze method;Group B adopts the winding finger method;Group C adopts the progressive V-shape method.Results The pain rate and bleeding rate of the three squeezing methods were compared,and the differences were statistically significant(P<0.05).Among them,the pain rate and bleeding rate of the fingerwound method were the highest;the comparison of the single squeeze times of the three methods showed that the difference was significant.Statistical significance(F=36.069,P<0.001);comparison of the patency rates of the three methods before and after extrusion,the difference in patency rates of group C before and after extrusion was statistically significant(χ^(2)=6.725,P<0.05),suggesting the progressive V method The squeeze has the best effect.Conclusions The progressive V-shaped method has a moderate number of single squeezing,the drainage tube has the best patency effect,and there are fewer pain and bleeding complications after squeezing.It does not affect the comfort of the patient and does not increase the burden on the operator.It is more suitable for PTCD tube squeezing.The preferred method of compression.
