Summary

This study evaluates the effect of the single-injection adductor canal block in patients receiving total knee arthroplasty under spinal anesthesia.

Detailed description

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.

Conditions

• Total Knee Arthroplasty

Interventions

Type	Name	Description
PROCEDURE	adductor canal block	After the end of the surgery, at the arrival of PACU, the patient's leg is prepared and draped in a sterile manner. Assisted by the high-frequency linear ultrasound transducer, we target the mid-thigh level and the 22-gauge/8cm needle is introduced in plain through the sartorius muscle. the correct position for the tip of the needle in the adductor canal is checked and a bolus injection of 0.5% ropivacaine 15ml is given.
