Isoflurane v fentanyl for outpatient laparoscopy

Area of Science:

• Anesthesiology
• Surgical Procedures

Background:

• Outpatient laparoscopy requires careful anesthetic selection for rapid recovery.
• Comparing anesthetic agents is crucial for optimizing patient care and minimizing side effects.

Purpose of the Study:

• To compare the efficacy and recovery profiles of isoflurane and fentanyl as anesthetic agents for outpatient laparoscopy.

Main Methods:

• A randomized study involving 50 female patients undergoing laparoscopy.
• Anesthesia induced with thiopentone, maintained with nitrous oxide/oxygen and either isoflurane or fentanyl.
• Recovery assessed by eye opening, time to recall birth date, and hourly monitoring for side effects.

Main Results:

• Immediate recovery was significantly faster in the fentanyl group (P < 0.05).
• Isoflurane patients showed return to baseline reaction times by 3 hours; fentanyl patients remained 10% slower at 4 hours (P < 0.05).
• Nausea, vomiting, and need for naloxone were more frequent in the fentanyl group.

Conclusions:

• Both isoflurane and fentanyl provided satisfactory anesthesia for outpatient laparoscopy.
• Isoflurane demonstrated a superior recovery profile with fewer adverse effects compared to fentanyl.
