Sevoflurane induction procedure: cost comparison between fixed 8% versus incremental techniques in pediatric patients

Area of Science:

• Anesthesiology
• Pediatric Medicine
• Pharmacoeconomics

Background:

• Inhalation induction is a common method for pediatric anesthesia.
• Sevoflurane is widely used for pediatric inhalation induction.
• Evaluating the economic and safety profiles of different induction techniques is crucial for clinical practice.

Purpose of the Study:

• To compare the economic outcomes of incremental versus fixed 8% sevoflurane inhalation induction in pediatric patients.
• To determine the relationship between induction cost and patient demographic parameters.
• To assess the safety and acceptability of both induction methods.

Main Methods:

• A randomized controlled trial involving 100 pediatric patients undergoing ophthalmologic examinations.
• Patients were divided into two equal groups receiving either incremental or fixed 8% sevoflurane induction.
• Sevoflurane consumption was measured using the Dion method; procedural costs were calculated.

Main Results:

• The fixed 8% method achieved faster loss of consciousness (76 vs 135 seconds).
• The incremental method consumed significantly less sevoflurane (2.25 mL vs 4.46 mL), nearly halving consumption.
• The incremental method resulted in lower overall procedural costs, saving approximately $18 per patient.

Conclusions:

• The incremental sevoflurane induction method is more economical than the fixed 8% method for pediatric anesthesia.
• Sevoflurane consumption during induction is independent of pediatric patient age, weight, or sex.
• Both induction methods are equally safe and acceptable for pediatric patients.
