目的 比较超声引导下采用不同浓度罗哌卡因行收肌管阻滞（ACB）对全膝置换术（TKA）后镇痛效果及股四头肌肌力的影响。
方法 选取拟在喉罩全麻下行单侧膝置换手术患者60例，男33例，女27例，年龄50~75岁，BMI 17~25 kg/m2，ASA Ⅰ—Ⅲ级，随机分为三组：0.25%罗哌卡因组（R1组）、0.375%罗哌卡因组（R2组）和0.5%罗哌卡因组（R3组），每组20例。患者均于术毕即刻于超声下行术侧ACB。记录术后4、8、12、24、48 h静息和运动时的VAS评分，记录术前1 d、术后4、8、12、24、48 h的股四头肌肌力分级，记录术前1 d、术后24、48 h膝关节活动度（ROM），并记录术后48 h内PCIA内舒芬太尼使用量，补救镇痛次数，恶心呕吐、尿潴留等并发症的发生情况。
结果 与术后4 h比较，术后12、24、48 h R1组静息和运动VAS疼痛评分明显升高（P＜0.05）。与R1组比较，术后12、24、48 h R2、R3组静息和运动VAS疼痛评分明显降低（P＜0.05）。与术前1 d比较，术后4、8、12、24 h R1组、R2组股四头肌肌力明显降低（P＜0.05）；术后4、8、12、24、48 h R3组股四头肌肌力明显降低（P＜0.05）。与R3组比较，术后48 h R1组、R2组股四头肌肌力明显升高（P＜0.05）。与术前1 d比较，术后24、48 h三组ROM明显降低（P＜0.05）；与R1组比较，术后24、48 h R2、R3组ROM明显升高（P＜0.05）。与R1组比较，R2、R3组术后48 h内PCIA内舒芬太尼使用量明显减少，补救镇痛率、恶心呕吐和尿潴留发生率明显降低（P＜0.05）。
结论 全膝关节置换术后镇痛采用0.375%罗哌卡因收肌管阻滞较0.25%浓度镇痛效果明显，减少术后阿片类药物使用量及并发症，较0.5%浓度有更强的股四头肌肌力及更高的膝关节活动度，有助于患者的术后快速康复。 |

Ojective To compare the postoperative analgesia and quadriceps strength among patients undergoing total knee arthroplasty (TKA) with different concentration ropivacaine by ultrasound-guided adductor canal block (ACB).
Methods Sixty patients scheduled to undergo unilateral TKA with general anesthesia, aged 50-75 years, BMI 17-25 kg/m2, ASA physical status Ⅰ-Ⅲ, were recruited. They were randomly divided into three groups, 0.25% ropivacaine (group R1), 0.375% ropivacaine (group R2) and 0.5% ropivacaine (group R3). All patients were conducted ACB by ultrasound immediately after surgery. VAS pain scores of resting and active conditions at 4, 8, 12, 24, and 48 h after operation were recorded. Grades of quadriceps strength were recorded at 1 d before and 4, 8, 12, 24, and 48 h after operation. The joint activity range of motion (ROM) was recorded on preoperative 1 d and 24 h, 48 h after operation. Sufentanil dosage within PCIA, supplement times of analgesia, complications such as nausea and vomiting, and urinary retention within 48 h after operation were recorded.
Results Compared with 4 h after operation, VAS pain scores of resting and active conditions in group R1 were significantly increased at 12, 24, 48 h after operation (P < 0.05). The VAS pain scores of resting and active conditions in groups R2, R3 12, 24, 48 h after operation were significantly lower than those in group R1 (P < 0.05). Compared with 1 d before operation, quadriceps muscle strength of group R1, R2 decreased significantly 4, 8, 12, 24 h after operation (P < 0.05). The quadriceps muscle strength of group R3 decreased significantly 4, 8, 12, 24, 48 h after operation (P < 0.05). Quadriceps strength in group R3 48 h after operation were significantly lower than those in groups R1 and R2 (P < 0.05). The ROM in groups R1, R2, R3 at 24, 48 h after operation were significantly lower than 1 d before operation (P < 0.05). The ROM in groups R2, R3 24, 48 h after operation were significantly higher than group R1 (P < 0.05). Amount of sufentanil dosage in PCIA, times of analgesia rescue, nausea, vomiting, and urinary retention within 48 h after operation in groups R2, R3 were significantly lower than group R1 (P < 0.05).
Conclusion Compared with 0.25% ropivacaine, ACB with 0.375% ropivacaine produces better analgesic effect, less postoperative opioid use and adverse events in TKA. Additionally, it has better quadriceps strength and higher joint activity range of motion than 0.5% ropivacaine, which is conductive to the rapid postoperative rehabilitation. |
