Abstract:
Objective:To analyze the influential factors of blurred vision after general anesthesia.Methods:The clinical data of 997 patients who underwent elective general anesthesia at The No. 1 People's Hospital of Pinghu from September 2022 to May 2023 were retrospectively analyzed. The data collected included age, sex, body mass index, American Society of Anesthesiologists classification, history of hypertension, history of diabetes, operation duration (specifically whether it exceeded 3 hours), surgical position (whether the patient was in the supine position), operating room temperature, use of penehyclidine hydrochloride, use of muscle relaxant antagonists, use of atropine, blood pressure (specifically whether it was ≥ 30% of the baseline value), fluid input, blood loss, and use of pneumoperitoneum. Collinearity diagnosis and univariate logistic regression analysis were conducted to select factors with statistical significance. Subsequently, multivariate logistic regression analysis was performed.Results:Univariate and multivariate logistic regression analyses showed that age > 65 years ( OR = 1.47, 95% CI: 1.01-2.15, P = 0.043), surgical position (non-supine position) ( OR = 1.54, 95% CI: 1.06-2.25, P = 0.025), operation time exceeding 3 hours ( OR = 1.76, 95% CI: 1.05-2.94, P = 0.031), and the use of penehyclidine hydrochloride ( OR = 4.91, 95% CI: 3.35-7.21, P < 0.001) were identified as factors contributing to postoperative blurred vision in patients undergoing general anesthesia. Conclusion:Factors contributing to postoperative blurred vision in patients undergoing general anesthesia include age > 65 years, the use of penehyclidine hydrochloride during surgery, operation time exceeding 3 hours, and non-supine surgical position. Clinically, it is essential to implement early and effective preoperative education, enhance intraoperative nursing quality, and optimize preoperative medication for general anesthesia to reduce the incidence of blurred vision after surgery.
