Active Comparator: Control Group; Bupivacaine + opioids
This is the "standard of care" arm. This group will receive pre-operative opioid education and "standard of care", which consists of an injection of 10cc bupivacaine (plus ~1cc epinephrine and bicarbonate) into the carpal tunnel and overlying skin pre-operatively, and a post operative prescription for opioids (oxycodone/acetaminophen 5/325). Pain scores and medication usage will be tracked for three days post operatively to assess the validity and efficacy of differing pain management strategies.
|
Other: Differing pain management strategy
The investigators aim to investigate an alternative (vs "standard") pain management strategy for post operative carpal tunnel release. All drugs used are FDA approved for these indications, and no drug itself is being investigated. |
Experimental: Experimental Group: Exparel, no opioids
This group will receive pre-operative opioid education, Exparel injection (liposomal bupivacaine, with bupivacaine, epinephrine and bicarbonate), and would not receive a prescription for opioids. This injection will be administered as 10cc injected in the operative field, consisting of ~5cc of Exparel (liposomal bupivacaine), ~5cc of bupivacaine, and ~1cc epinephrine. Pain scores and medication usage will be tracked for three days post operatively to assess the validity and efficacy of differing pain management strategies.

- Evaluation of post operative pain levels via Visual Analog Scale [ Time Frame: Within the first few months of study duration ]The investigators aim to evaluate pain in either arm of the study, followed over a three day course. As several studies have shown pain to be wholly or mostly resolved by post-operative day three. Patients will answer questionnaire to include Visual Analog Scale for pain, and amount of pain medication taken. The Visual Analog Scale for pain ranges from a score of 0 to 10, with 0 being "no pain", 5 being "distressing pain", and 10 being "the worst pain imaginable"
- Failure of alternate pain management strategy [ Time Frame: Within the first few months of study duration ]The investigators aim to identify any subset of patients that do not respond to combination therapy (education + Exparel). Analysis of data provided by patient-answered Visual Analog Scale will occur. Failures will be presented as a whole number and as percentage of total participants.
