Perioperative High-flow Nasal Oxygen in Patients Undergoing Robotic Surgery

Perioperative High-flow Nasal Oxygen in Patients Undergoing Robotic Surgery: A Randomized Trial

The aim of the study is to assess whether perioperative use of high-flow nasal oxygen (HFNO) during the period from induction of anesthesia until discharge from the post-anesthesia care unit in patients undergoing robotic-assisted surgery reduces perioperative oxygen desaturation and postoperative pulmonary complications.

The investigators hypothesize that perioperative HFNO reduces perioperative oxygen desaturation and reduces postoperative pulmonary complications in patients undergoing robotic-assisted surgery.

Inclusion Criteria:

• Age >= 18
• Undergoing non-emergent, non-cardiac, intra-abdominal, intra-thoracic or pelvic robot-assisted surgery with an expected duration of at least 2 hours under general anesthesia with planned extubation at the end of the procedure

Exclusion Criteria:

• Known pregnancy
• Preoperative intubation or tracheostomy
• Anatomical or clinical conditions precluding the use of high-flow nasal oxygen (severe midface trauma, recent nasal surgery, severe nasal septum deviation, severe nasal deformation)
• Contraindications to electrical impedance tomography (EIT), including inability to place the EIT belt or presence of active implantable electronic devices (e.g., pacemaker or implantable cardioverter-defibrillator)
• Planned postoperative admission to the intensive care unit
