Postoperative discomfort including nausea, vomiting, dizziness, and headache was recorded and quantified. Univariable and multivariable logistic regression were performed to detect the risk factors associated with postoperative discomfort.Results: Of 210 participants, 199 (94.76%) patients experienced mild discomfort after ambulatory strabismus surgery under general anesthesia, and 31 (14.76%), 11 (5.24%), 60 (28.57%), 23 (10.95%) patients suffered from nausea, vomiting, dizziness, and headache, respectively. A multivariate analysis indicated that female sex, the surgery on inferior rectus, and the surgery on inferior oblique were the independent risk factors for postoperative vomiting while, mild anxiety was the independent risk factor for postoperative dizziness.Conclusion: Patients undergoing ambulatory strabismus surgery tended to experience postoperative nausea and dizziness. Female sex, the surgery on inferior rectus, mild anxiety, and the surgery on inferior oblique were the independent predictors of postoperative discomfort.Keywords: postoperative nausea and vomiting, dizziness, strabismus surgery, ambulatory surgery, related factors
