Abstract Objective: To analyze the influencing factors of postoperative abdominal distension in patients with osteoporotic vertebral compression fractures (OVCFs). Method: The clinical data of 154 patients with OVCFs treated in Wuhan Orthopedic Hospital of Integrated Traditional Chinese and Western Medicine from January 2020 to June 2022 were retrospectively analyzed, and the risk factors of postoperative abdominal distension in patients with OVCFs were analyzed. Result: Among 154 patients with OVCFs, 33 cases (21.43%) of abdominal distension occurred after surgery. There were no significant differences in age, gender, hypertension, body mass index (BMI), smoking history, ASA classification, required fasting before surgery and postoperative eating time between the patients with or without abdominal distension (P>0.05). There were significant differences in anesthesia methods, unused patient-controlled analgesia (PCA), frequency of getting out of bed, antibiotic use and bed time between the patients with or without abdominal distension (P>0.05). logistic regression analysis showed that, general anesthesia [OR=2.880, 95%CI (1.131, 7.332)], unused PCA[OR=4.538, 95%CI (1.687, 12.213)], getting out of bed less than 3 times/d [OR=5.711, 95%CI (2.042, 15.973)], used antibiotics [OR=2.901, 95%CI (1.136, 7.403)], bed duration ≥5 d [OR=6.231, 95%CI (2.185, 17.766)] were risk factors for postoperative abdominal distension in patients with OVCFs (P<0.05). Conclusion: The incidence of postoperative abdominal distension in patients with OVCFs is high, and its occurrence is affected by the way of anesthesia, the use of PCA, the frequency of getting out of bed, the use of antibiotics, and the time in bed, clinical evidence can be used to give targeted intervention to reduce the occurrence of postoperative abdominal distension.
