Summary

The use of local anesthetics has become an important aspect of pain management in surgical settings and is currently recommended in pain management guidelines.

Elective outpatient hand surgeries, such as carpal tunnel or trigger finger release, cause minimum tissue disruption and are short in duration. As a result, these local anesthetic agents are a major component in post-operative pain control. The most commonly used local anesthetic agents are Lidocaine and Bupivacaine. Lidocaine acts faster (within 2-5 minutes of injection) and for this reason is often favored in outpatient setting for pre-incisional injection. However its effects only last up to 2 hours, without epinephrine, and 3 hours, with epinephrine. On the other hand, Bupivacaine, has a slower onset of action (about 5-10 minutes after injection) but its effects last much longer, for about 4-8 hours. The delay in onset of action makes it a less popular option as a primary source of local anesthesia in outpatient hand surgery.

Given the longer duration of anesthesia offered by Bupivacaine, the investigators believe that by giving it pre-operatively in elective outpatient hand surgeries will offer more effective post operative pain control compared to using Lidocaine only. There is limited published data confirming the effectiveness of use of pre-operative Bupivicaine in improved postoperative pain control and decreased consumption of narcotics. Therefore, the aim in this study is to compare the postoperative pain experienced by patients undergoing either elective carpal tunnel release or trigger finger release as well as their use of pain medications when the incision site is infiltrated preemptively with Lidocaine versus Bupivacaine.

The investigators believe that adequate post surgical pain control is essential for patients' full functional recovery. Poorly controlled post surgical pain increases incidence of surgery related complications and thus increased health care costs. It can also reduce patients' mobility, delay their return to full function,. If poorly controlled, post surgical pain may progress to chronic pain and rarely complex regional pain syndromes may ensue.
