Abstract

Objectives: A randomized, double-blind comparison of the effect of lidocaine 2% combined with adrenaline (LA) ratio 1:100.000 and 1:200.000 in Sub-brow lift surgery. Subjects and methods: A randomized, double-blind, controlled clinical intervented study on 40 patients who underwent Sub-brow lift surgery under local anesthesia adrenaline combined with lidocaine 2%. They randomly received lidocaine 2% with 1:100,000 adrenaline (group 1) or lidocaine 2% with 1:100,000 adrenaline (group 2) from January 2019 to October 2020 at Vietnam National Eye Hospital. Results: VAS score at 2h, 6h, and 10h of group 1 is better than group 2. The operation time and intraoperative anesthetic drug dosage of group 1 are less than group 2. The intraoperative blood loss and hematoma rates were similar in the two groups. The postoperative welling score in the two groups was significant           (p < 0,005). All patients were satisfied, and group 1 had a higher level of satisfaction. Conclusion: Sub-brow lift surgery under local anesthesia of lidocaine 2% combined with adrenaline produces desirable anesthesia effects. LA 1:100.000 can significantly reduce postoperative pain and mitigate postoperative swelling, with better satisfaction.
