Anaesthesia for laparoscopy: alfentanil and fentanyl compared
Annals of the Royal College of Surgeons of England
|September 1, 1983
Summary
Alfentanil and fentanyl are potent analgesics used in anesthesia. Alfentanil demonstrated a faster onset of spontaneous breathing and fewer required anesthesia supplements compared to fentanyl.
Area of Science:
- Anesthesiology
- Pharmacology
Background:
- Opioid analgesics like alfentanil and fentanyl are crucial in modern anesthesia.
- Understanding their comparative efficacy and safety profiles is essential for clinical practice.
Purpose of the Study:
- To compare alfentanil and fentanyl as analgesic components in anesthesia for gynecological laparoscopy.
- To evaluate differences in anesthetic requirements, recovery, and hemodynamic effects.
Main Methods:
- A double-blind, comparative study involving 66 women undergoing laparoscopy.
- Patients received either alfentanil (0.75 mg) or fentanyl (0.25 mg) combined with methohexitone, alcuronium, nitrous oxide, and oxygen.
Main Results:
- Fewer patients receiving alfentanil required intraoperative enflurane supplementation compared to fentanyl.
- Recovery from anesthesia was similar, but spontaneous breathing returned more rapidly after alfentanil.
- Fentanyl administration was associated with a significant drop in blood pressure and a slower pulse rate compared to alfentanil.
Conclusions:
- Alfentanil offers advantages over fentanyl in terms of faster respiratory recovery and potentially reduced need for additional anesthetic agents.
- Both analgesics are effective, but alfentanil may provide a more favorable hemodynamic profile and quicker recovery in this specific surgical context.
