Defining the Best Approach to Block the Pain After Knee Surgery - Full Text View

Sponsor:	McGill University Health Center
Information provided by:	McGill University Health Center
ClinicalTrials.gov Identifier:	NCT00294073

Purpose

The study aims to compare standard techniques used to control pain after knee surgery. The investigators hypothesize that the fascia iliaca block is faster, safer and as good as or better than the femoral block, with or without a stimulating catheter.

Condition	Intervention	Phase
Pain, Postoperative	Procedure: Fascia Iliaca Block Procedure: Femoral Block (with stimulating catheter) Procedure: Femoral Block (without stimulating catheter)	Phase III

Study Type:	Interventional
Study Design:	Allocation: Randomized Endpoint Classification: Safety/Efficacy Study Intervention Model: Parallel Assignment Masking: Double-Blind Primary Purpose: Treatment
Official Title:	Defining the Best Approach to Block the Pain After Knee Surgery

Further study details as provided by McGill University Health Center:

Primary Outcome Measures:

pain relief; measured by VAS at rest and on activity [ Time Frame: before surgery, before discharge from PACU and on evenings of days 1, 2, 7, 60, 90 ]
pain relief; measured by WOMAC [ Time Frame: before surgery and at days 7, 60, 90 ]
pain relief; evaluated from standard datasheet [ Time Frame: over 48-hour period ]

Secondary Outcome Measures:

knee range of bending [ Time Frame: measured before surgery, and at days 7, 60, 90 ]
thigh circumference 20 cm above the knee [ Time Frame: measured before surgery and at days 7, 60, 90 ]
neurological exam of femorocutaneous, femoral and obturator nerves [ Time Frame: evaluated once spinal anesthesia has worn off, post-surgery, before anesthesia ]
level of activity; measured using questionnaire [ Time Frame: at 7-10 days and at 2 and 3 months ]
need for rescue analgesia [ Time Frame: in recovery room and at home ]
need for second bolus or crossing over between groups

Estimated Enrollment:	60
Study Start Date:	July 2005

Detailed Description:

60 patients being treated for ACL repair or knee arthroplasties under regional anesthesia will be randomized to three groups: Fascia Iliaca Block (FIB), Femoral Block (FB) with stimulating catheter or FB without stimulating catheter. A catheter will be placed according to each technique, before the surgery. A bolus of local anesthetic will be given pre-surgery and at the end of the operation, in all groups. A continuous infusion will be started for 48 hours. All patients receive a standard analgesia cocktail and rescue medication.

Pain and level of activity, as well as side effects, will be evaluated.
