Continuous Infraclavicular Blocks: Neurostimulation Versus Ultrasound
- Conditions
- Disorder of Upper Extremity
- Interventions
- Procedure: Ultrasound
- Registration Number
- NCT01136447
- Lead Sponsor
- Lawson Health Research Institute
- Brief Summary
The purpose of this study is to determine whether ultrasound guidance or nerve stimulation is the best option for placing continuous peripheral nerve block catheters for upper limb surgery.
- Detailed Description
In a multidisciplinary, observer blinded, prospective, single center, randomized study, success rate of US guided versus neurostimulation guided catheter placement for continuous infraclavicular block in patients scheduled for upper limb surgery will be studied. Block effectiveness, time taken, discharge from recovery, postoperative pain and disability and patient acceptance will be studied in 210 patients.
