Details and patient eligibility

About

This research study is to determine if the insertion site of a perineural catheter or tiny tube placed next to the nerves that go to the part of the body (hand or arm) having surgery, affects the amount of pain relief that is experienced after surgery. Catheters will be placed in either the supraclavicular or infraclavicular location.

Full description

To determine if a particular perineural local anesthetic catheter location (supraclavicular or infraclavicular) will maximize postoperative analgesia, minimize oral opioid requirements, minimize sleep disturbances resulting from postoperative pain, and maximize patient satisfaction.

  • patients who have any known contraindication to study medications
  • insulin-dependent diabetes mellitus
  • neuropathy of any etiology in the affected extremity
  • contraindication to regional blockade (e.g. clotting deficiency)
  • any known acute or chronic hepatic or renal insufficiency or failure

60 participants in 2 patient groups

1. Supraclavicular
Active Comparator group
Description:
Patients will be randomized to placement of a nerve block in the supraclavicular position. After the catheter has been placed, sensory and motor deficit will be assessed and following surgery, for the next three days, the patient will be contacted by research staff to assess pain scores and other outcome measures.
Treatment:
Procedure: Supraclavicular vs. Infraclavicular ropivicaine infusion
2. Infraclavicular
Active Comparator group
Description:
Patients will be randomized to placement of a nerve block in the infraclavicular position. After the catheter has been placed, sensory and motor deficit will be assessed and following surgery, for the next three days, the patient will be contacted by research staff to assess pain scores and other outcome measures.
Treatment:
Procedure: Supraclavicular vs. Infraclavicular ropivicaine infusion
