Outcome Measures

Primary Outcomes (1)

  • Duration of Sensory Nerve Block

    The primary outcome will be time to resolution of the nerve block as assessed by pinprick over the saphenous nerve distribution. Testing will occur every two hours.

    12 to 48 hours

Secondary Outcomes (5)

  • Verbal Pain Scores

    0 to 30 hours

  • Rate of Post Operative Nausea and Vomiting

    0 to 30 hours

  • Neurologic Complications

    throughout study completion, up to 48 hours

  • Post Operative Opioid Use and Consumption

    0-30 hours

  • Time to First Opioid Analgesic Request

    0 to 36 hours

Study Arms (3)

4 mg Perineural Dexamethasone Group

EXPERIMENTAL

4 mg of dexamethasone will be included in the saphenous nerve block mixture including 20 ml of 0.25% bupivacaine with 1:400,000 epinephrine. No systemic dexamethasone will be given.

1 mg Perineural Dexamethasone Group

EXPERIMENTAL

1 mg of dexamethasone will be included in the saphenous nerve block mixture including 20 ml of 0.25% bupivacaine with 1:400,000 epinephrine. No systemic dexamethasone will be given.

Placebo Group

PLACEBO COMPARATOR

This group will receive only the saphenous nerve block mixture including 20 ml of 0.25% bupivacaine with 1:400,000 epinephrine. Dexamethasone will not be administered to this group systemically or perineural.
