PENG Block vs. Local Anesthetic for Hip Replacement Anesthesia

N/A

Recruiting

Led By Shalini Dhir, FRCPC

Research Sponsored by London Health Sciences Centre Research Institute and Lawson Research Institute of St. Joseph's

Eligibility Criteria Checklist

Specific guidelines that determine who can or cannot participate in a clinical trial

Must have

Undergoing THA with a direct lateral surgical approach (transgluteal approach)

Be older than 18 years old

Timeline

Screening 3 weeks

Treatment Varies

Follow Up 6-24 hours following completion of spinal anesthesia

Summary

This trial will study a new technique called the pericapsular nerve group (PENG) block for patients undergoing hip replacement surgery. The current standard treatment involves injecting a mix of local anesthetic,

Who is the study for?

This trial is for adults over 18 years old who are having a total hip arthroplasty (hip replacement surgery) using a specific surgical approach. Participants must be able to give consent. It's not suitable for those with conditions that rule out the use of local anesthetics or nerve blocks.

What is being tested?

The study compares two pain management methods in hip surgery: PENG block, which numbs certain nerves, and the standard care involving local anesthetic infiltration possibly mixed with morphine and NSAIDs. The goal is to see if PENG can match or exceed current methods in pain relief and cost-effectiveness.

What are the potential side effects?

Potential side effects may include discomfort at the injection site, numbness beyond the targeted area, allergic reactions to medications used, and less commonly nerve damage or infection from the procedure.

Experimental Treatment

Placebo Group

Group I: PENG BlockExperimental Treatment1 Intervention

Participants will receive ultrasound-guided PENG block (PENG group) with local anesthetics (20 ml of 0.5% ropivacaine) before administration of spinal anesthesia.

Group II: Control GroupPlacebo Group1 Intervention

Participants will receive a sham PENG block performed with 20ml of normal saline solution before spinal anesthesia. After, patients will receive ILAI (performed by the operating surgeon) with a plain solution of ropivacaine 0.25% 60ml.
