- PURPOSE: To evaluate the efficacy of combination of lidocain and bupivacain as preemptive analgesia in vitrectomy with or without sclera buckle under general anesthesia. METHODS: Twenty eight patients who were scheduled for vitrectomy were included in this study. The patients were randomly divided into two equal groups. The surgery was done under general anesthesia in both groups, but in Group 1, subTenon anesthesia with local anesthetic was given as preemptive analgesia after induction anesthesia and before start of surgery. Pain intensity is the primary outcome of this study. The pain intensity was measured in 3 hours and 24 hours after surgical procedure. RESULTS: The baseline characteristic between the two groups was similar. The pain intensity was lower in the treatment group, but the difference is not statistically significant (1,00±1,71 VS 1,50±2,16, p=0,109). The proportion of pain free patients are similar between two groups in 3 hours post procedure (65% VS 65%, p=1,00). The proportion of pain free patients are higher in the treatment gropus in 24 hours post procedure (100% VS 73%, p=0,222, Fisher Exact Test). The sub-tenon injection procedure is safe. There are not significance difference in the incidence of sie eeffects betwee the 2 groups. CONCLUSION: This study does not show any additional benefit of sub-tenon injection for vitrectomy. The pain intensity was similar between two groups. There are not increases of side effects after the procedure.
