Effects of abdominal electrical stimulation combined with airway clearance on cough ability and success rate of extubation in patients with severe tracheotomy
Objective:To observe the effect of abdominal electrical stimulation combined with airway clearance on cough ability and success rate of extubation in patients with severe tracheotomy.Method:A randomized,double-blind,controlled trial was conducted.52 patients with tracheotomy who met the inclusion criteria were divided into a control group and an experimental group,with 26 cases in each group.The experimental group was treated with abdominal electrical stimulation on the basis of airway clear-ance technique.The observation period was 6 weeks.Before and after treatment,involuntary cough peak flow rate(ICPF),clinical pulmonary infection score(CPIS),tracheal tube extubation time and extubation success rate were used to compare the differences in clinical efficacy.Result:Before the training,there was no significant difference in ICPF between the two groups(P>0.05),but at l,3 and 6 weeks,the ICPF score of the experimental group was significantly higher than that of the con-trol group(P<0.05).Before training,there was no significant difference in CPIS score between the two groups(P>0.05),but after 1,3 and 6 weeks,the CPIS score of the experimental group was significantly lower than that of the control group,and the difference was statistically significant(P<0.05).Before training,there was no significant difference in abdominal muscle thickness between the two groups(P>0.05).At the 3rd and 6th week,the abdominal muscle thickness of the experimental group was significantly higher than that of the control group,and the difference was statistically significant(P<0.05).The extubation time of the experimental group was significantly shorter than that of the control group(P<0.05).The success rate of extu-bation in the experimental group was 92%,which was significantly higher than that in the control group(76%),and the difference was statistically significant(P<0.05).Conclusion:Abdominal electrical stimulation combined with airway clearance can significantly improve the cough ability of patients with severe tracheotomy,shorten the time of tracheal cannula removal,and improve the success rate of extubation.
