Feasibility Study on Selecting the Size of I-gel Laryngeal Mask Airway Based on the Size of the Large Thenar Bulge
Objective To evaluate the feasibility of selecting the size of children's I-gel laryngeal mask based on the size of the large thenar bulge.Methods A total of 120 children who underwent general anesthesia surgery in the Department of Pediatric Surgery of our hospital from October 2022 to January 2024 were included as study objects.According to random number table method,the children were divided into control group and study group,with 60 cases in each group.The control group selected the I-gel laryngeal mask model according to the weight-specification table provided by the manufacturer,and the study group matched the laryngeal mask specifications with the most similar long and wide diameters according to the large thenar length and width.The first implantation success rate,implantation time,adjustment rate during anesthesia,air leakage rate and postoperative complications were compared between groups.The differences of blood oxygen saturation(SpO2),end-respiratory CO2 partial pressure(PetCO2)and airway peak pressure(Ppeak)were recorded before laryngeal mask placement,5 min after laryngeal mask placement,30 min after surgery,5 min before surgery and after laryngeal mask removal.Results There were no significant differences in the success rate,time,adjustment rate during anesthesia and air leakage rate between the two groups(P>0.05).There was no significant difference in SpO2,PetCO2 between the two groups at each time point(P>0.05).There was no significant difference in the incidence of complications such as blood staining of laryngeal mask,sore throat,hoarseness,nausea,vomiting and dysphagia among groups(P>0.05).Conclusion The reliability of the I-gel laryngeal mask selection method based on the size of the large thenar bulge is similar to that based on the weight selection method,which provides a new method for the selection of laryngeal mask specifications for children who cannot know the weight parameters in emergency situations.
