Abstract

Aims: To measure changes in optic nerve diameter during lower extremity trauma surgery and to compare changes in patients under general and spinal anesthesia. Methods: A prospective observational study was conducted on 50 patients undergoing lower extremity trauma surgery, of whom 26 received general anesthesia and 24 received spinal anesthesia. Data on basic patient profile, surgery, anesthesia, and optic nerve diameter were collected before surgery, 10 minutes after dural puncture or induction of anesthesia, and 10 minutes after recovery from motor block. Descriptive statistical analysis and Spearman's index were used to study the correlation between the two groups (general and spinal anesthesia). Results: The study population consisted of 25 males and 25 females, age 63.40 ± 16.36 years, weight 77 ± 10.66 kg, duration of surgery 93.20 ± 23.659 min. 28 cases required ischemic management, duration 58.15 ± 10.57 min. Preoperative optic nerve measurements were 5.06 ± 0.89 mm in the right eye and 4.45 ± 0.7955 mm in the left eye; intraoperatively: 5.70 ± 0.77 mm in the right eye and 4.84 ± 0.75 mm in the left eye; and postoperatively: 4.91 ± 0.88 mm in the right eye and 4.46 ± 0.64 mm in the left eye. The data were similar in both groups. Preoperative (p<0.01) and postoperative data were bilaterally statistically significant between the two groups. Conclusions: The optic nerve diameter increased after both spinal and general anesthesia and it returned to preoperative data in the immediate postoperative period.
