Abstract:
Objective:To explore the application value of a novel bag respirator assisted ventilation device in postoperative transport under general anesthesia with laryngeal mask.Methods:A total of 133 patients in postoperative transport who underwent elective bron-choscopy or treatment under general anesthesia with laryngeal mask in the First Affiliated Hospital of Chongqing Medical University,from June to August 2023 were selected.The patients were randomly divided into control group(n=65)and experimental group(n=68),and received manual bag respirator assisted ventilation and the novel bag respirator assisted ventilation device during their postop-erative transport,respectively.The pulse oxygen saturation(SpO2),heart rate(HR),and ventilation frequency during transport,trans-port duration,and transport-related adverse events were compared between the two groups.Results:The difference in SpO2 was signifi-cant when comparing the two groups(Fbetween groups=18.588,P<0.001),and the SpO2 of patients in the experimental group was signifi-cantly higher than that of patients in the control group during and after transport(P<0.001).The difference in HR was not significant when comparing the two groups(Fbetween groups=0.089,P=0.766),but it was significant between the control and experimental groups before and after transport(Ftime point=12.430,P<0.001);the HR in the con-trol and experimental groups before and during transport was signifi-cantly lower than that after transport(all P<0.001).The ventilation frequency of the experimental group was significantly lower than that of the control group(P<0.001).The transport duration in the ex-perimental group was longer than that in the control group,but the difference was not significant(P=0.987).Both groups successfully completed the trial without transport-related adverse events and achieved safe transport.Conclusion:Compared with the manual bag respirator assisted ventilation technology,the novel bag respirator assisted ventilation device for respiratory support during postopera-tive transport in patients under general anesthesia with laryngeal mask is more able to reduce the impact on the patient's hemodynam-ics and conducive to the maintenance of the patient's stable vital signs,showing a good clinical application value.It is expected to be a safe and effective ventilation method during intrahospital transport in some patients under general anesthesia.
