RÉSUMÉ
@#Objective To explore predictive value of modified STOP-BANG questionnaire(MSBQ)for hypoxemia during painless gastroscopy.Methods A total of 300 patients were selected as the study subjects who underwent painless gastroscopy in Zhejiang Cancer Hospital from October to December 2021.The MSBQ and STOP-BANG questionnaire(SBQ)were used for assessment before the examination,and patients were divided into high risk group(total score≥3 points)and low risk group(total score<3 points)according to their scores.The incidence of hypoxemia in high risk group and low risk group of the two scales was observed.The predictive value of MSBQ and SBQ for the risk of hypoxemia during painless gastroscopy was evaluated by receiver operating characteristic(ROC)curve.Results The incidence of hypoxemia in high risk group was significantly higher than that in low risk group(P<0.05).The sensitivity of MSBQ and SBQ to predict the occurrence of hypoxemia in painless gastroscopy was 81.01%and 83.54%,the specificity was 78.28%and 66.06%,and the area under the curve was 0.81 and 0.79,respectively.The prediction efficiency of MSBQ was better.Conclusion MSBQ has a high predictive value for the risk of hypoxemia in painless gastroscopy.
