简要总结
This study evaluates the effect of the single-injection adductor canal block in patients receiving total knee arthroplasty under spinal anesthesia.
详细描述
This study aims to evaluate the effect of the single-injection adductor canal block in patients receiving total knee arthroplasty under spinal anesthesia. The effect of the single-injection adductor canal and continuous adductor canal block in patients receiving total knee arthroplasty under general anesthesia has been well established. However, due to the residual effect of spinal anesthesia, the effect of the single-injection adductor canal block needs to be determined. The investigators hypothesize that the single-injection adductor canal block will decrease the total sum of 2h, 6h, 12h, and 24h pain score.

结局指标
主要结局
the sum of pain score
时间窗: 2 hours, 6 hours, 12 hours, and 24 hours after intervention
VAS pain score (0 to 10) is measured using numeric pain rating scale at 2 hours, 6 hours, 12 hours, and 24 hours 0: no pain, 10: worst pain
次要结局
- Postoperative nausea and vomiting(2 hours, 6 hours, 12 hours, and 24 hours after intervention)
