Abstract:
Objective:To assess the safety,effectiveness and economy of some brands and models of domestic and imported anesthesia machine in clinical application,so as to provide reference for improving the competitiveness of anesthesia machine of domestic brands.Methods:A total of 195 patients who underwent general anesthesia in surgery through used respectively domestic Mindray WATO-EX-55Pro anesthesia machine,and imported GE CS620 and GE Aelite NXT anesthesia machines at Inner Mongolia People's Hospital from January 2021 to January 2023 were selected.According to the different brands of the used anesthesia machine by the patients,they were divided into domestic Mindray WATO-EX-55Pro anesthesia machine group(Domestic group),imported GE Aelite NXT anesthesia machine group(Import group of NXT)and imported GE CS620 anesthesia machine group(Import group of 620),with 65 cases in each group.Based on the clinical application data of anesthesia machines in real-world,the actual application effects of anesthesia machines of different brands were assessed in terms of 3 aspects included effectiveness,safety and economy.Results:In the indicators about effectiveness,there was statistically significant difference in postoperative blood oxygen saturation among the Domestic group[100%(99%,100%)],Import group of NXT[99%(98%,100%)]and Import group of 620[99%(99%,100%)](Z=14.723,P<0.05).There was statistically significant difference in the different value of blood oxygen saturation between before and after surgery among three groups(Z=-1.681,P<0.05),and there was significant difference in the postoperative partial pressure of carbon dioxide(PCO2)among three groups(Z=5.574,P<0.05).There was no statistically significant difference in the other indicators of effectiveness among three groups(P>0.05).In the indicators about safety,there was no statistically significant difference in the incidence of adverse events among the three groups(P>0.05).In the indicators about economy,the total costs of anesthesia for patients were respectively 1190.00 CNY(870.00,1582.50),2650.00 CNY(2357.50,2928.75)and 2462.00 CNY(1657.50,2847.50)in the Domestic group,Import group of NXT and Import group of 620,and the difference of that among three groups was statistically significant(Z=88.825,P<0.05).Conclusion:There are not significant differences in the analyzed effectiveness and safety among the domestic anesthesia machine and the imported anesthesia machines,and domestic anesthesia machine is more economical than imported anesthesia machines,which can reduce the cost of anesthesia in surgery,and alleviate the financial burden of patients in medical expenses.
