简要总结
The purpose of this study is to compare infraclavicular brachial plexus shot single shot block to continuous catheter nerve block done in adult patients who have under gone surgery to repair distal radius fractures. Visual analogue scores, opioid consumption, quality of recovery and quality of sleep up to 72 hours post operatively will be used for comparison.
详细描述
If the patient is willing to participate and signs the consent, he/she will be randomized to one of the two treatment groups:
- Single shot block
- Continuous catheter
In the institution investigators usually advocate for regional anesthesia and intravenous sedation for the repair of open fracture of the distal radius.
Patients will be monitored during block performance with standard ASA monitors. All patients will receive 2 L of oxygen via a nasal cannula. Sedatives will be titrated to effect. Midazolam 1-2 mg, and fentanyl 50-100 mcg will be used for sedation.
Block time out will be preformed according to standard operating procedure. All blocks will be done under ultrasound guidance. Sonosite S nerve machine will be used with a low frequency curvilinear (C5) US probe with 2-5 MHZ frequency. Both single shot and continuous ICB will be performed according to the SOP in the department. Ultrasound survey of the deltopectoral groove below the clavicle will take place. The axillary artery and the three cords (posterior, medial and lateral) of the brachial plexus will be identified in short axis view deeper to the pectoralis minor muscle.

研究组 & 干预措施
continuous IBP block
Subjects will receive 60 hour continuous infraclavicular brachial plexus block (0.2% of ropivacaine at 8 milliliter/hour) with initial four intermittent 5ml bolus (20ml) of 0.5% Ropivicaine given preoperatively to help with operative and postoperative pain
干预措施: 20ml bolus of 0.5% ropivicaine (Drug)
