Manual vs AutoFlow ventilation during anesthesia induction in older adults

Official title: Effects of Manual Versus Autoflow Ventilation During Anesthesia Induction on Cerebral and Peripheral Oxygenation in Geriatric Patients

Run by Ankara City Hospital Bilkent · NCT07582913 · Data updated 2026-11-12

This study tests whether AutoFlow ventilation during induction of general anesthesia helps keep brain and body oxygen levels steadier in people aged 65 and older compared with manual mask ventilation.

Is this trial a fit for you?

Likely a good fit

Adults aged 65 years and older scheduled for elective surgery with general anesthesia and endotracheal intubation, ASA I–III, able to consent.

Probably not a fit

Patients with severe heart or lung disease, brain tumors or prior stroke, cognitive impairment, difficult airway, or sensor/material allergies may not benefit.

What this trial studies

This prospective, single-center randomized trial compares manual mask ventilation to AutoFlow mechanical ventilation during anesthesia induction in geriatric patients. It assesses cerebral oxygen saturation (s-rSO₂) and peripheral oxygen saturation (p-rSO₂) to determine which method provides more stable oxygen delivery during the onset of anesthesia. The study accounts for age-related physiology that can affect oxygenation and aims to identify whether a predefined, controlled ventilation strategy reduces episodes of hypoxemia or hypocapnia. Participants are adults 65+ undergoing elective surgery with endotracheal intubation, without severe cardiopulmonary disease or cognitive impairment. The trial seeks to inform best practices for airway management and intra-induction oxygenation in the elderly.

Why it matters

Potential benefit: If AutoFlow proves more stable, it could reduce risks related to cerebral and peripheral oxygen desaturation during anesthesia induction in older patients.

How similar studies have gone: Previous research in ventilation strategies suggests controlled, automated ventilation can improve oxygenation stability, but evidence specific to AutoFlow during induction in geriatrics is limited.
