新型气管导管气囊压力检测器的研发及临床应用效果OA

Objective:To evaluate the development of a self-made new type of pressure detector with endotracheal tube for airbag and its clinical practice and application effect in reducing postoperative complications.Methods:The airbag's pressure of new type of pressure detector with endotracheal tube for airbag was detected,which was connected with module of detecting pressure through single chip machine,and the pressure was continuously detected.A total of 244 patients,who underwent gastrointestinal surgery at Wuhan Hospital of Traditional Chinese Medicine and Tongji Hospital,Tongji Medical College of Huazhong University of Science and Technology from February 2023 to February 2024,were selected,and they were divided into a control group and an observation group by random number table method,with 122 cases in each group.Both groups received conventional surgical treatment,the airbag's pressures of the tubes of patients of control group were judged and maintained by anesthesiologists with more than 5 years of working experience according to their clinical experience(finger touch method)during surgery period,and the observation group adopted the new type of pressure detector with endotracheal tube for airbag to detect airbag's pressure.Both groups used standard pressure gauge(20-30 cmH2O)for airbag to verify the pressure of airbag.The endotracheal tube-related complications,airbag's pressure of the endotracheal tube,and various prognostic indicators among different time stages(instant after intubation,at intraoperatively fixed time,and the time before extubation)were compared.Results:At the 24th hour after the operation,38 cases occurred cough and 26 cases occurred throat pain in the observation group,which incidence rates were significantly lower than those in the control group,and the differences of them between the two groups were statistically significant(x2=11.388,12.739,P<0.05).In one month after the operation,there was not hoarseness in the observation group,while 4 cases occurred hoarseness in the control group,and the incidence rate of the observation group was significantly lower than that of the control group,and the difference between the two groups was statistically significant(x2=4.067,P<0.05).The normal rates of airbag's pressure of endotracheal tube at instant after intubation,at intraoperatively fixed time,and the time before extubation were respectively 90.16%,90.98%,and 91.80%in the observation group,and there were statistically significant differences between the two groups(x2=11.091,10.583,11.017,P<0.05).The airbag's pressures at instant after intubation,at intraoperatively fixed time,and the time before extubation were respectively(38.36±4.25),(28.36±5.54)and(24.55±2.55)cmH2O in the observation group,which were significantly lower than those in the control group,and the differences were statistically significant(t=10.366,12.366,11.544,P<0.05).The curative satisfaction degree of patients in the observation group was 91.80%,which was significantly higher than 75.41%of patients in the control group,and the difference was statistically significant(x2=11.167,P<0.05).The satisfaction degree of 40 medical staffs for the usage of equipment in the observation group was 90.00%,and for that in the control group was 67.50%,and the difference was statistically significant(x2=6.050,P<0.05).Conclusion:The research about the new type of pressure detector with endotracheal tube for airbag's pressure can meet the clinically actual requirements.Its functions in automatic monitoring and regulation can accurately detect airbag's pressure.The endotracheal tube-related complications of patients at different time stages were significantly reduced,and the airbag's pressure value tends to be normal,and the hospital stay of patients is shortened,and the satisfaction of patients and medical staffs is improved.
