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

Type	Name	Description
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
