Withdrawal forces of lumbar spinal catheters: no dependence on body position.

BACKGROUND Spinal catheters, because of their smaller diameter, have lower tensile strength than epidural catheters. This study was designed to measure the withdrawal forces needed to remove lumbar spinal catheters and to determine whether patient position affects withdrawal forces. METHODS Eighty-two patients with a 24-gauge spinal catheter placed… CONTINUE READING
