A double-blind randomized prospective study comparing prilocaine versus ropivacaine in upper blepharoplasty.

Abstract

Upper blepharoplasties are a common procedure in plastic surgery. This procedure can be performed effectively under local anesthesia with or without sedation. The ideal local anesthetic should cause less intraoperative bleeding and less postoperative edema. Our study aimed to show the difference between the two local anesthetics 1% prilocaine (Xylonaest) in combination with epinephrine 1:100,000 and ropivacaine (Naropin) in combination with epinephrine 1:100,000 including sodium chloride, particularly in regard to swelling and bleeding in patients undergoing upper blepharoplasties. In this double-blind, prospective, randomized study, 31 patients between March 2014 and September 2014 were included. The anesthetic agents used in all cases were 1% prilocaine (Xylonaest) in combination with epinephrine 1:100,000 for one side and ropivacaine consisting of 10-mg Naropin, 5-ml sodium chloride, and 1-ml epinephrine for the other side. The data presented in this study were collected by one of the surgeons performing the surgery. Intraoperative bleeding and postoperative edema were both calculated using a score of five points for each. The average bleeding tendency was 3.39 for prilocaine and 1.71 for local ropivacaine, showing a significant difference (p < 0.0001) between both local anesthetics in bleeding tendency. There was also a significant minor swelling at all times on the side on which ropivacaine was used. In our study, we demonstrated that ropivacaine (Naropin) has less intra- and postoperative side effects including swelling and bleeding compared with prilocaine (Xylonaest).
