The effects of end-tidal controlled low-flow anesthesia on anesthetic agent consumption in elective surgeries: randomized controlled trial.

ABSTRACT:

Purpose

The environmental impact and cost of volatile anesthetics are significant concerns in modern anesthesia. Automated end-tidal control systems aim to optimize anesthetic delivery by reducing waste and improving efficiency. This study compared the effectiveness of end-tidal controlled (EtControl) low-flow anesthesia to manually controlled (MC) low-flow anesthesia in elective surgeries.

Design

A randomized controlled trial.

Methods

This study was conducted with 132 ASA Class I-II patients undergoing elective surgeries under general anesthesia. Patients were randomly assigned to the EtControl (n = 66) or MC (n = 66) groups. The primary outcomes included anesthetic agent consumption (mL).

Findings

Anesthetic consumption was similar between the EtControl group
