|Official Title:||Standard Supraclavicular Block Versus Low-Volume Supraclavicular Block Plus Ulnar or Median Nerve Block for Hand Surgery in the Ulnar or Median Nerve Distribution|
|Study Start Date :||March 2012|
|Actual Primary Completion Date :||July 2013|
|Estimated Study Completion Date :||December 2015|
Experimental: Combined nerve block
Participants in this group will receive a supraclavicular brachial plexus block plus a median or ulnar nerve block.
Procedure: Combined nerve block
Combined supraclavicular brachial plexus block plus ulnar or median nerve block (depending on the location of surgery)
Active Comparator: Single nerve block
Participants in this group will receive a supraclavicular brachial plexus block only.
Procedure: Supraclavicular block
Standard supraclavicular brachial plexus block
- Successful anesthesia, defined as no additional local anesthetic or heavy sedation required. [ Time Frame: From injection of local anesthetic to suitable nerve blockade for surgery; approximately 20 minutes ]Successful anesthesia will be determined by assessing the nerve block(s) following injection of local anesthetic, and deeming the block sufficient enough for surgery to proceed without any need for additional local anesthetic or heavy sedation. The period between the initial injection and successful anesthesia is approximately 20 minutes, depending on the patient.
- Time to successful anesthetic block from withdrawal of final needle [ Time Frame: Approximately 20 minutes ]The period between final withdrawal of the needle to successful nerve block following assessment will be timed.
- Time for procedure, from placement of probe on skin to withdrawal of needle [ Time Frame: Approximately 30 minutes ]The period between initial placement and positioning of the ultrasound probe on the patient to final withdrawal of the needle will be timed.
- Duration of analgesia [ Time Frame: Approximately 6 hours ]The length of time between successful nerve block (i.e., when patient is ready for surgery) to the time the anesthesia wears off will be sought.
- Duration of motor blockade [ Time Frame: Approximately one hour ]The time taken for the patient to recover motor capability in the area anesthetized following local anesthetic injection will be determined.
- Patient satisfaction [ Time Frame: 24-48 hours ]Patient satisfaction with reduction of pain and recovery of motor capability will be assessed in the 24-48 hour period following surgery.
