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.

Further study details as provided by Halyard Health:

Primary Outcome Measures:
  • Complications of Peripheral Nerve Block [ Time Frame: Preoperative through 3 days post operative ]
    Adverse events related to performance of peripheral nerve catheter placement for continuous infusion of local anesthetic

Enrollment: 1821
Study Start Date: May 2007
Study Completion Date: March 2009
Primary Completion Date: March 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: USPNB
Ultrasound imaging guided peripheral nerve block
Device: Ultrasound imaging
Ultrasound guided techniques for placement of peripheral nerve block catheters for continuous infusion of local anesthetic
Active Comparator: NSPNB
Peripheral nerve stimulator guided peripheral nerve block catheter placement for continuous infusion of local anesthetic
Device: Peripheral nerve stimulator
either stimulating needle or stimulating catheter used for placement of catheter for continuous infusion of local anesthetic

Detailed Description:

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.
