A Phase 4 interventional study of Lidocaine and Fentanyl in Post-induction Hypotension, Lidocaine and Opioid, sponsored by Cairo University. Completed at 1 site in Egypt. Open to participants aged 18 Years to 65 Years. Per ClinicalTrials.gov, last updated 2026-03-05.
Sponsored by Cairo University · Phase 4, Interventional, and Other
Lidocaine-based anesthesia had been recently reported as a successful regimen for induction of anesthesia in elderly population with better hemodynamic profile than opioid-based induction. The investigators hypothesize that lidocaine-based induction of anesthesia would provide superior hemodynamic profile compared to conventional opioid-based induction of anesthesia in emergency laparotomy.
Cairo University is the lead sponsor of 4,780 studies on the registry; 1,427 are open to participants now.
Of its 36 completed or terminated interventional studies of FDA-regulated products, 5 (14%) have results posted.

Exclusion Criteria:
Patients will receive 1 mg/kg lidocaine intravenously (IV)
Drug: Lidocaine · Drug: Propofol · Drug: Succinyl choline
Patients will receive 1 mcg/kg fentanyl intravenously (IV)
Drug: Fentanyl · Drug: Propofol · Drug: Succinyl choline
After preoxygenation with 100% oxygen for 3 minutes, the study drug (lidocaine) will be administered. Patients will receive 1 mg/kg lidocaine of 10 mg/mL lidocaine solution (prepared by diluting 5 mL of lidocaine 20% in saline to a total volume of 10 mL)
After preoxygenation with 100% oxygen for 3 minutes, the study drug (fentanyl) will be administered. Patients will receive 1 mcg/kg fentanyl of 10 mcg/mL fentanyl solution (prepared by diluting 100 mcg fentanyl in saline to a total volume of 10 mL).
After administration of the study drug, all patients will receive 2 mg/kg propofol intravenously
After loss of consciousness, 1 mg/kg succinyl choline will be administered over 5 seconds, and tracheal intubation will be done through direct laryngoscopy after 60 seconds.
