Multicenter Continuous Peripheral Nerve Block Surveillance Study Comparing Ultrasound Guided Catheter Placement to Non Ultrasound Guided Catheter Placement Techniques

This two tiered study is a multi-center, open label, surveillance study of the use of
continuous nerve blocks with the ON-Q® C-bloc and either nerve stimulator or ultrasound
guided continuous nerve block techniques. This study was developed to investigate specific
aspects of complication rates related to continuous nerve block techniques in patients
undergoing orthopedic surgical procedures.

Continuous peripheral nerve block techniques require the placement of catheters near target
peripheral nerves. The placement of these catheters is guided by either ultrasound
visualization, nerve stimulation or a combination of the two.

This surveillance study was designed to look at the rates of catheter placement related
complications with the two techniques.
