Impact of CO2 on Cerebral Blood Flow in Infants Less Than 6 Months During General Anaesthesia

Impact of CO2 on Cerebral Blood Flow in Infants Less Than 6 Months During General Anaesthesia

The study aims at assessing cerebral blood flow variations following expired CO2 variations in anaesthetized infants less than 6 months, during a routine general anesthesia.

The study aims at assessing cerebral blood flow (measured with Near-Infrared Reflectance Spectroscopy - NIRS - and transcranial Doppler - DTC) variations following end-tidal expired CO2 variations in anaesthetized infants less than 6 months, during a routine general anesthesia performed according to standards of care.

Inclusion Criteria:

• Age < or = 6 months
• ASA class < or = 3
• General anesthesia required for surgery

Exclusion Criteria:

• No parental consent
• Emergency surgery
• Preexisting neurological condition
• Hemodynamic instability
• Preexisting hypoxemia and/or hypercapnia
• Laparoscopy or thoracoscopy, if expected EtCO2 level achieving would require unsafe ventilation parameters
