The authors compared the efficacy of local anesthetics levobupivacaine, bupivacaine, and lidocaine for retrobulbar anesthesia in vitreoretinal surgery.
A total of 135 patients presenting for vitreoretinal surgery under local anesthesia were included in the study. Patients were randomly allocated to one of three groups. Group LB patients received 5 mL of 0.5% levobupivacaine, Group L patients received 5 mL of 2% lidocaine, and Group B patients received 5 mL of 0.5% bupivacaine for retrobulbar anesthesia via inferotemporal injection. Sensory and motor block durations were recorded. Intraoperative and postoperative pain was assessed by using verbal pain scala. Anesthesia efficiency, patient and surgeon satisfaction, and akinesia were assessed by using point scales. Hemodynamic data and adverse events were recorded.
The demographic characteristics of patients, duration of surgery, and hemodynamic data in both groups were similar. The duration of motor and sensory block was longer in levobupivacaine and bupivacaine groups than lidocaine group. Pain on injection was found more frequent in Group L and Group B than Group LB and the difference between the Groups LB and B was significant (p<0.05). Surgeon and patient satisfaction were also higher and intraoperative pain was less in levobupivacaine group than lidocaine and bupivacaine groups.
Levobupivacaine provides longer motor and sensory block duration and higher surgeon and patient satisfaction than lidocaine and bupivacaine when used for retrobulbar anesthesia in vitreoretinal surgery.
作者比较了局部麻醉药左布比卡因、布比卡因和利多卡因在玻璃体视网膜手术中球后麻醉的效果。
本研究纳入了135例接受局部麻醉下玻璃体视网膜手术的患者。患者被随机分配到三组中的一组。LB组患者接受5毫升0.5%左布比卡因，L组患者接受5毫升2%利多卡因，B组患者接受5毫升0.5%布比卡因，通过颞下注射进行球后麻醉。记录感觉和运动阻滞持续时间。使用言语疼痛量表评估术中及术后疼痛。使用评分量表评估麻醉效果、患者和外科医生满意度以及眼球运动麻痹情况。记录血流动力学数据和不良事件。
两组患者的人口统计学特征、手术时间和血流动力学数据相似。左布比卡因组和布比卡因组的运动和感觉阻滞持续时间比利多卡因组长。L组和B组注射时疼痛比LB组更频繁，LB组和B组之间的差异具有统计学意义（p<0.05）。左布比卡因组的外科医生和患者满意度也更高，术中疼痛比利多卡因组和布比卡因组更少。
在玻璃体视网膜手术中用于球后麻醉时，左布比卡因比利多卡因和布比卡因提供更长的运动和感觉阻滞持续时间，以及更高的外科医生和患者满意度。
