What this trial studies

This study investigates the pharmacokinetic profile of lidocaine administered as a weight-based intravenous infusion for postoperative pain control in surgical patients. It aims to map serum lidocaine levels over time in a diverse population undergoing elective major surgeries. The study will involve blood sample collection to measure lidocaine concentrations and assess its effectiveness in pain management. The research is conducted at the University of Alberta Hospital over a duration of one year with a target enrollment of 40 participants.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-40 or over 75, classified as ASA class 1-3, scheduled for elective major surgeries where lidocaine infusion is appropriate.

Not a fit: Patients with a history of hypersensitivity to lidocaine or amide local anesthetics, or those requiring epidural or regional anesthesia techniques may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide an effective alternative to opioids for managing postoperative pain.

How similar studies have performed: Previous studies have shown that intravenous lidocaine infusions can effectively manage acute perioperative pain, suggesting a promising approach.
