Summary

This study compares the long-axis and short-axis technique of continues adductor canal block for total knee replacement surgery. Half participants will receive long-axis catheterization, while the other half will receive short-axis catheterization.

Conditions

  • Total Knee Arthroplasty
  • Analgesia
  • Nerve Block

Interventions

PROCEDURE

ultrasound guided long axis placement of adductor canal catheter

The long axis of the ultrasound probe is placed parallel to the long axis of the adductor canal while scanning, and the catheter is placed along the long axis of the canal using an in-plane approach

PROCEDURE

ultrasound guided short axis placement of adductor canal catheter

The long axis of the ultrasound probe is placed vertical to the long axis of the adductor canal while scanning, and the catheter is placed along the short axis of the canal using an in-plane approach

DEVICE

Philip CX 50 Ultrasound Scanner

The linear (C5-12) probe of Philip CX 50 Ultrasound Scanner is used for scanning

DEVICE

PAJUNK Contiplex S Catheter

DRUG

Ropivocaine

0.2% ropivacaine 10ml is given as loading dose. Following that, 0.2% ropivacaine 5ml/h is given as maintenance dose.

DRUG

rescue sulfentanil given postoperatively as PICA

bolus: 2mg, lock time: 10min, 1h limitation: 8mg
