PURPOSE
To compare pain on injection of two modified anesthetic lidocaine solutions for use in upper blepharoplasty: 2% lidocaine with 1:100,000 epinephrine, and 2% lidocaine with 1:100,000 epinephrine buffered 9:1 with 8.4% sodium bicarbonate.
METHODS
In this prospective, double-masked study, 25 consecutive patients undergoing upper blepharoplasty were submitted to the anesthesic procedure. Each eyelid received one of two modified lidocaine solutions. Heart rate, systemic arterial pressure and oxygen saturation level were obtained before, during and after injection of two different anesthetic solutions. Patients used a 4-point scale to rate the perceived pain on injection.
RESULTS
All parameters were statistically analyzed and there was a significant difference in heart rate and oxygen saturation level.
CONCLUSION
Pain on injection of eyelid anesthesia does not differ significantly with either buffered or unmodified lidocaine solutions.
目的
比较两种用于上睑成形术的改良麻醉利多卡因溶液注射时的疼痛情况：2%利多卡因加1:100,000肾上腺素，以及2%利多卡因加1:100,000肾上腺素并与8.4%碳酸氢钠按9:1缓冲。
方法
在这项前瞻性、双盲研究中，25例连续接受上睑成形术的患者接受麻醉程序。每只眼睑接受两种改良利多卡因溶液中的一种。在注射两种不同麻醉溶液之前、期间和之后获取心率、体动脉压和氧饱和度水平。患者使用4分制量表对注射时感知到的疼痛进行评分。
结果
对所有参数进行统计学分析，心率和氧饱和度水平存在显著差异。
结论
眼睑麻醉注射时的疼痛在缓冲利多卡因溶液和未改良利多卡因溶液之间无显著差异。
