一种耳挂式胃管固定装置的设计与应用效果评价

Observation on the design and application effect of one kind of fixator of gastric tube by ear-hanging

设计一种耳挂式胃管固定装置用于临床。选取60例行留置胃管的住院患者,依据胃管固定方式的不同将其分为耳挂式组(30例)和传统式组(30例),比较两组胃管固定装置使用情况、使用效果评价和住院患者满意度情况;比较两组胃管平均留置时间、固定材料平均更换时间以及重置胃管例数数据,观察并评价其临床应用效果。耳挂式组平均留置时间、更换胃管材料时间及重置胃管例数均优于传统式组,其差异有统计学意义(t=6.464,t=8.592,t=2.282;P<0.05);比较两组胃管脱出情况、胃管远端皮肤情况及远端固定舒适情况,耳挂式组均优于传统式组,其差异具有统计学意义(x^(2)=5.455,x^(2)=5.247,x^(2)=13.469;P<0.05);耳挂式组住院患者满意率为96.67%,优于传统式组的50%,差异有统计学意义(x^(2)=47.78,P<0.05)。应用耳挂式胃管固定装置可有效减少胃管固定材料更换频次及时间,延长胃管留置时间,减少患者皮肤刺激情况及患者不适反应,有效降低非计划拔管率。

To design a gastric tube fixator by ear-hanging and 60 patients who admitted to hospital and underwent indwelling gastric tube were selected.They were divided into ear-hanging group(30 cases)and general group(30 cases)according to different fixed form of gastric tube.The service condition and evaluation of use for gastric tube,and satisfaction of inpatients between two groups were compared.The data of the average indwelling time of gastric tube,the average replacement time of fixed material and the number of cases of gastric tube replacement between two groups were compared,and the clinical application effect of them were observed and evaluated.The results indicated that these indicators of ear-hanging group were significantly better than that of general group(t=6.464,t=8.592,t=2.282,P<0.05).The prolapse,the conditions of distal skin and the comfort of distal fixation of gastric tube in ear-hanging group were significantly superior than those in general group(x^(2)=5.455,x^(2)=5.247,x^(2)=13.469,P<0.05),respectively.The satisfaction rate of ear-hanging group(96.67%)was significant higher than that of general group(50.0%)(x^(2)=47.78,P<0.05).The fixator of gastric tube by ear-hanging can effectively reduce the frequency and time of replacement of fixation material of gastric tube,and prolong the indwelling time of gastric tube,and reduce the skin irritation and adverse reaction of patients,and effectively decrease the rate of unplanned extubation.
