Remifentanil-based anesthesia versus a propofol technique for otologic surgical procedures

Area of Science:

• Anesthesiology
• Neurosurgery

Background:

• Otologic microsurgery demands a stable surgical field, often compromised by patient movement.
• Emetic symptoms (nausea and vomiting) occur in approximately 50% of patients undergoing otologic procedures.
• Propofol effectively reduces emetic symptoms but does not significantly control intraoperative movement.

Purpose of the Study:

• To compare the efficacy of remifentanil/propofol versus propofol/fentanyl anesthetic combinations for otologic microsurgery.
• To evaluate perioperative conditions, including surgical field stability, patient movement, and recovery parameters.
• To determine the optimal anesthetic strategy for enhancing patient outcomes in otologic procedures.

Main Methods:

• Eighty healthy patients were randomized into two groups, receiving either remifentanil/propofol or propofol/fentanyl anesthesia.
• Key variables monitored included demographic data, hemodynamic status, intraoperative movement, bispectral index, and emergence characteristics.
• Postoperative outcomes such as nausea, vomiting, and pain were assessed using appropriate statistical analyses.

Main Results:

• The remifentanil group exhibited significantly shorter times to eye opening (7.7 vs. 12.4 minutes) and extubation (9.8 vs. 12.4 minutes).
• Patients receiving remifentanil demonstrated reduced intraoperative movement (23% vs. 65%) and lower hemodynamic variability.
• While postoperative pain was mild in both groups, the remifentanil group reported slightly higher pain levels compared to the propofol group.

Conclusions:

• Remifentanil-based anesthesia provides superior hemodynamic stability and reduced intraoperative movement during otologic surgery.
• This anesthetic combination facilitates faster patient emergence compared to propofol/fentanyl, while propofol maintains its antiemetic benefits.
• Remifentanil/propofol anesthesia offers an effective and cost-efficient alternative for optimizing perioperative conditions in otologic microsurgery.
