Observing the effects of low flow anesthesia on waste gas emissions
The Effect of Two Different Fresh Gas Flows on Inhaled Gas Consumption During Wash-in Period in Patients Undergoing Low Flow Anesthesia: An Observational Study
Balikesir University · NCT06967948
This study is testing how different levels of gas flow during anesthesia affect the amount of waste gas released into the air and the costs of the anesthetic used, with volunteers aged 18 to 60 participating.

What this trial studies
This observational study involves volunteers aged 18 to 60 who will undergo general anesthesia while their brain response to anesthetic agents and the concentration of inhaled anesthetics will be monitored. The researchers aim to evaluate the impact of different fresh gas flow rates (1 to 4 l/min) on the amount of waste gas released into the atmosphere and the associated costs of inhalation agents. By analyzing the relationship between gas flow rates and environmental impact, the study seeks to identify more sustainable anesthesia practices.
Who should consider this trial
Good fit: Ideal candidates are ASA I-II risk group patients undergoing surgeries lasting between 2 to 4 hours that require general anesthesia.
Not a fit: Patients with severe lung disease, significant cardiac issues, or those who have recently undergone chemotherapy or radiotherapy may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could lead to reduced environmental impact and lower costs associated with inhalation anesthesia.
How similar studies have performed: While the approach of reducing fresh gas flow rates is established, the specific focus on environmental impact and cost reduction in this context is relatively novel.
