Condition(s) targeted: Fracture of Ankle

Intervention: Dexamethasone (Drug); Dexamethasone (Drug); Saline (Drug)

Phase: Phase 4

Status: Completed

Sponsored by: Northwestern University

Rohit Rahangdale, MD, Principal Investigator, Affiliation: Northwestern University, Feinberg School of Medicine

Summary

Patients scheduled to have foot and ankle surgery will typically receive a single shot sciatic nerve block to serve as the primary anesthetic and as part of a multi-modal post-operative analgesic plan. The investigators are investigating the use of perineural dexamethasone together with local anesthetics can improve the quality of recovery for patients receiving sciatic nerve blocks for foot and ankle surgery.

Clinical Details

Official title: The Effects of Perineural Versus Intravenous Dexamethasone on Sciatic Nerve Blockade Outcomes

Study design: Allocation: Randomized, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator), Primary Purpose: Supportive Care

Primary outcome: Quality of Recovery

Secondary outcome:

Opioid Consumption

Pain Scores

Detailed description: Patients scheduled to have foot and ankle surgery will typically receive a single shot sciatic nerve block to serve as the primary anesthetic and as part of a multi-modal post-operative analgesic plan. Perineural dexamethasone has been investigated as an adjuvant for brachial plexus nerve blocks but its effect on sciatic nerve block outcomes has yet to be determined. More importantly, it is not known whether the beneficial effect of perineural dexamethasone on analgesia duration leads to a better quality of surgical recovery. We hypothesized that perineural dexamethasone leads to a better quality of postsurgical recovery than intravenous dexamethasone or saline control.
