Abstract Objective To investigate the influence of short-cut endotracheal intubation on the offline success rate of patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD).Methods Retrospective analysis of 80 patients with AECOPD who had undergone oral and tracheal intubation mechanical ventilation and blood gas analysis in the department of critical caremedicine from January 2019 to August 2019 in our hospitalwere selected as the experimental group.From January to August 2018,the 80 patients with AEDPD who underwentmechanical ventilation and blood gas analysis of the intubation in the ICU were shown to have typeⅡrespiratory failure and who had met the criteria for weaning were selected as the control group.Both groups of patients were given conventionalmedical treatment,and invasive mechanical ventilation was performed through oral intubation.When the patients reached the offline standard,the control group underwent SBT according to the routine operation.The experimental group removed the tracheal intubation connector and shortened the length of the tracheal tube to 25cm after the development line,and then performed SBT.The indexes of respiratory rate,heart rate,shallow respiratory index,oxygenation index,pulse oximetry,tidal volume,oral closure pressure,and lung dynamic compliance after the extubation and offline success rate were compared between the two groups.Results The respiratory rate,heart rate and shallow respiratory index of the experimental group were lower than those of the control group,and the differences were statistically significant(P＜0.05).The oxygenation index,pulse oximetry,tidal volume,and oral closure pressure,the lung dynamic compliance in the experimental group were higher than those in the control group,and the differences were statistically significant(P＜0.05).The success rate of SBT in the experimental group was 93.75%,which was higher than that in the control group (73.75%)(P＜0.05).The intubation rate of the experimental group was 3.75%,which was lower than that of the control group(10.00%)(P＜0.05).The offline success rate in the experimental group was 90.00%,which was higher than that of the control group (63.75%),and the difference was statistically significant(P＜0.05).Conclusion When the endotracheal tube is cut short,the success rate of passing SBT test,weaning and extubation of AECOPD patients is increased,the length of stay in ICU and the cost of hospitalization is reduced,the curative effect is obvious,and social and economic benefits can be produced.
