title: Force exerted by epidural catheters.
abstract: In a study of epidural catheters, it was found that catheter material and catheter diameter both influenced in force exerted. Catheters made of nylon exert less force than those made of polyethylene. Diameter is proportional to the logarithm of force exerted.
