Comparing lidocaine and opioids for anesthesia in emergency surgery

Comparison of Hemodynamic Effect of Lidocaine-based Versus Opioid-based Induction of Anesthesia in Emergency Laparotomy: a Randomized Controlled Trial.

Phase 4 Interventional Cairo University · NCT06772727

This study tests whether using lidocaine instead of opioids for anesthesia during emergency surgery can help keep patients' blood pressure stable and improve their recovery.

What this trial studies

This study evaluates the effectiveness of lidocaine-based anesthesia compared to traditional opioid-based anesthesia in patients undergoing emergency laparotomy. The focus is on minimizing post-induction hypotension, a common complication associated with this type of surgery. The study involves adult patients classified as ASA class I-III and aims to maintain stable vital signs and adequate tissue perfusion during the procedure. Various anesthetic agents, including lidocaine, fentanyl, and propofol, will be administered to assess their impact on patient outcomes.

Who should consider this trial

Good fit: Ideal candidates are adult patients of both genders classified as ASA class I-III who require emergency laparotomy.

Not a fit: Patients with severe cardiac morbidities, uncontrolled hypertension, or those on vasopressor infusion may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to safer anesthesia protocols and improved outcomes for patients undergoing emergency laparotomy.

How similar studies have performed: Previous studies have shown promising results with lidocaine in various surgical settings, suggesting potential benefits in this novel application.
