Effects of Minimal and Metabolic Flow Sevoflurane Anesthesia in Gynecological Surgery Patients

NCT07465146 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 97

Last updated 2026-03-11

No results posted yet for this study

Summary

The aim of this study is to observe the effects of minimal and metabolically required basal anesthetic gas flow rates delivered by the anesthesia workstation under general anesthesia on body temperature, blood pressure, and heart rate during surgery.

It also aims to evaluate the impact of reducing excessive delivery of anesthetic gases, air, and oxygen beyond the patient's physiological needs during general anesthesia on minimizing the harmful effects of anesthetic gases on the environment, climate, and global warming, as well as on contributing positively to hospital costs.

Conditions

  • Low-flow Anesthesia

Interventions

PROCEDURE

Low Flow Anesthesia

Adjustment of fresh gas flow rates during general anesthesia using a modern anesthesia workstation (Getinge Flow-C). Patients will be randomized to receive anesthesia with either minimal flow (0.5 L/min) or metabolic flow (0.3 L/min). All other anesthetic agents and monitoring parameters will remain standardized according to institutional protocols.
