Abstract
Objective To analyze the occurrence of hypoxemia among patients undergoing painless gastroscopy for early gastric cancer screening and to identify associated risk factors.Methods A retrospective study included 180 patients who underwent early gastric cancer screening at Zhengzhou First People's Hospital from April 2023 to November 2024.Patients who developed hypoxemia were assigned to the hypoxemia group,and the remaining patients served as the control group.Baseline characteristics[age,sex,ethnicity,marital status,body mass index(BMI),history of smoking and alcohol consumption,habitual snoring,general health status],baseline measurements[airway classification,heart rate,and oxygen saturation(SPO2)],and examination-related variables for painless gastroscopy(propofol dose,examination duration,and number of endoscope insertions)were collected and compared between groups.Multivariate logistic regression was used to analyze risk factors for hypoxemia.Results In total,29 patients(16.11％)developed hypoxemia.Compared with the control group,the hypoxemia group had higher age,higher BMI,a higher proportion of habitual snoring,and a higher propofol dose,while preoperative baseline SPO2 was lower;these differences were statistically significant(P＜0.05).Multivariate logistic regression indicated that higher age and propofol dose,BMI classified as overweight/obese,and lower baseline SPO2 were associated with an increased risk of hypoxemia during painless gastroscopy.Conclusion During painless gastroscopy,special attention should be given to patients who are older,have a high BMI,report habitual snoring,have lower baseline SPO2,and receive higher propofol doses,as they are more likely to develop hypoxemia.Prophylactic measures should be implemented to prevent hypoxemia in these patients.关键词
