目的：评价单用布比卡因注射液的免置管浸润麻醉在玻璃体视网膜手术中的临床效果。

方法：选取在我院进行玻璃体视网膜手术的患者58例58眼，随机分为两组，观察组(28例28眼)采用单用布比卡因注射液的免置管浸润麻醉，对照组(30例30眼)采用传统Tenon囊下麻醉。运用NRS-11(the 11-point numeric rating scale，NRS-11)监测患者麻醉过程、巩膜切口、眼内操作过程中及手术结束时疼痛程度的情况，并记录两组患者心率、血压变化以及麻醉时间。

结果：两组患者麻醉过程、巩膜切口、眼内操作过程中及手术结束时NRS-11评分差异均无统计学意义(P>0.05)； 患者心率、血压变化差异亦均无统计学意义(P>0.05)； 两组麻醉时间比较差异有统计学意义(P<0.05)。

结论：单用布比卡因注射液可取得与利多卡因、布比卡因混合液相同的效果，免置管浸润麻醉耗时短，是一种安全、有效的麻醉方法。

METHODS: Fifty-eight patients(58 eyes)with vitreous retinal surgery were selected. Patients were randomly divided into observation group(28 eyes)and control group(30 eyes). The observation group were received non-catheter infiltration anesthesia. The control group were received traditional Sub-Tenon's block(STB). Degree of pain, basic vital signs, the duration of anesthesia and analgesia grade were recorded and compared between two groups.

RESULTS: No significant difference was found in the 11-point numeric rating scale(NRS-11 scoring)of anesthesia process, sclera incision, intraocular operation and the end of operation between two groups(P>0.05). The difference were not significant in heart rate and blood pressure between two groups(P>0.05). There was statistically significant difference in the duration of anesthesia between two groups(P<0.05).

CONCLUSION: Both groups can provide the same anesthetic effect. Compared to STB, non-catheter infiltration anesthesia takes short time, and it is a safe and effective anesthesia methods. In addition, compare to the mixture of bupivacaine and lidocaine injection, bupivacaine injection can provide the same anesthetic effect.
