【摘要】 目的 探讨改良STOP-BANG问卷（modified STOP-BANG questionnaire,MSBQ）对无痛胃镜检查低氧血症的预测价值。方法 选取2021年10月至12月于浙江省肿瘤医院行无痛胃镜检查的300例患者为研究对象，检查前以MSBQ和STOP-BANG问卷（STOP-BANG questionnaire,SBQ）进行评估，根据评分将患者分为高风险组（总分≥3分）和低风险组（总分<3分）。观察两个量表高风险组和低风险组患者的低氧血症发生率，采用受试者操作特征曲线（receiver operating characteristic curve,ROC曲线）评估MSBQ和SBQ对无痛胃镜检查低氧血症风险的预测价值。结果 两个量表高风险组患者的低氧血症发生率均显著高于低风险组（P<0.05）;MSBQ和SBQ预测无痛胃镜检查发生低氧血症的敏感度分别为81.01%、83.54%，特异性分别为78.28%、66.06%，曲线下面积分别为0.81、0.79,MSBQ的预测效能更好。结论 MSBQ对无痛胃镜检查低氧血症风险有较高的预测价值。更多还原

【Abstract】 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.更多还原
