Brief Summary:
An alternative to general anesthesia - which puts a patient completely to sleep - is regional anesthesia, where local anesthetic is injected under the skin to freeze or 'block' a nerve or set of nerves. This method allows a patient to be awake during surgery and avoids any unpleasant after-effects of general anesthetic. A regional block is normally performed by inserting a needle under the skin so that the needle tip is near the nerve to be blocked, followed by injection of a single shot of enough local anesthetic to block any sensation that the nerve normally provides. Although regional nerve blocks provide pain relief during a surgical procedure, they eventually wear off, occasionally leaving the patient to contend with localized pain in the part of the body that was operated on. In these cases, over-the-counter painkillers like Tylenol or Advil may not be strong enough to completely take away the pain. We believe that, instead of giving a single shot of anesthetic, patients can be fitted with a catheter - a thin, flexible tube - that can be used to deliver one dose of local anesthetic to block the nerve before surgery and which could also be used to deliver a second dose of anesthetic just prior to discharge from the hospital. This way, the patient still only receives one needle poke, but their pain can be better managed following surgery. Our study will compare the post-nerve block pain profiles of individuals who have received a single-shot injection of local anesthetic versus those who have received two doses via the catheter delivery method.

Arm Intervention/treatment
Experimental: Perineural catheter
Local anesthetic will be delivered through an indwelling perineural catheter
Procedure: Perineural catheter
Patients in the experimental group will receive a single dose of local anesthetic though an indwelling catheter both before and after surgery.
Active Comparator: Single-shot block
Local anesthetic will be delivered by the conventional, single-shot method.
Procedure: Single-shot block
Patients in the control group will receive a single shot of local anesthetic, in standard fashion, before surgery.

Primary Outcome Measures :
  1. Postoperative pain levels [ Time Frame: 24 hours following surgery ]
    Pain levels at surgery site following surgery (up to 24 hours post-surgery) will be assessed.

Secondary Outcome Measures :
  1. Patient comfort at home [ Time Frame: Post-operative period (approx. 24 hrs following surgery) ]
    Patient pain levels and effects on daily living/activities will be assessed following surgery.
