We compared the recovery profiles, postoperative complications, perioperative OR utilization times, and times to discharge of patients undergoing ambulatory knee arthroscopy under spinal anesthesia (SA) or general anesthesia (GA).
In this randomized, prospective study, 84 ASA I-II patients were randomized to receive either SA with 50 mg of 1% lidocaine, or a standardized GA. Postoperative pain, nausea and vomiting, sedation, OR utilization, postanesthesia care unit (PACU), and ambulatory surgical unit (ASU) recovery were compared.
Patients in the GA group had more pain in the PACU than the SA group (61% vs 15%, P <0.01), and a higher incidence of PACU analgesic use (59% vs 7.5%, P <0.01). Patients in the SA group were able to drink and eat sooner than the GA group (83 +/- 23 vs 95 +/- 22 min, P <0.05 and 88 +/- 27 vs 105 +/- 29 min, P <0.01, respectively). The times to sit, walk, and void were similar. The length of PACU and ASU stay between the GA and SA groups were similar (67 +/- 17 vs 60 +/- 19 min, P >0.05 and 122 +/- 27 vs 127.9 +/- 31 min, P >0.05, respectively). The incidence of backache was higher in the SA group (35 vs 13.6%, P <0.05) than the GA group. However, the incidence of sore throat was higher in the GA compared to the SA group (25% vs 2.5%, P <0.01).
SA with 50 mg of 1% lidocaine provides an improved recovery profile for ambulatory knee arthroscopy. Discharge times were similar, and with the exception of backache and sore throat, the incidence of complications was similar.
我们比较了在脊髓麻醉（SA）或全身麻醉（GA）下接受门诊膝关节镜检查患者的恢复情况、术后并发症、围手术期手术室使用时间以及出院时间。
在这项随机、前瞻性研究中，84例ASA I-II级患者被随机分为接受50mg 1%利多卡因的SA组或标准化GA组。比较术后疼痛、恶心呕吐、镇静情况、手术室使用情况、麻醉后护理单元（PACU）和门诊手术单元（ASU）的恢复情况。
GA组患者在PACU的疼痛程度高于SA组（61%对15%，P<0.01），PACU使用镇痛药的发生率也更高（59%对7.5%，P<0.01）。SA组患者比GA组患者更早能够进食和饮水（分别为83±23分钟对95±22分钟，P<0.05；88±27分钟对105±29分钟，P<0.01）。坐起、行走和排尿时间相似。GA组和SA组在PACU和ASU的停留时间相似（分别为67±17分钟对60±19分钟，P>0.05；122±27分钟对127.9±31分钟，P>0.05）。SA组背痛的发生率高于GA组（35%对13.6%，P<0.05）。然而，GA组咽痛的发生率高于SA组（25%对2.5%，P<0.01）。
50mg 1%利多卡因的SA为门诊膝关节镜检查提供了更好的恢复情况。出院时间相似，除背痛和咽痛外，并发症发生率相似。
