Optic nerve sheath diameter-guided extubation plan in obese patients undergoing robotic pelvic surgery in steep Trendelenburg position: A report of three cases

Perioperative optic nerve sheath diameter variations in patients with end-stage renal failure undergoing robotic-assisted kidney transplant: a prospective observational study

“…CO 2 retention, airway edema, and delayed awakening due to increased ICP make extubation a risky procedure and can postpone recovery. ONSD has been utilized to guide extubation decisions in patients with obesity [ 25 ]. None of our patients experienced delayed recovery from anesthesia, and the mean ONSD measurement before extubation (T5) was 3.54±0.47 mm [ 26 ].…”

Atelectasis after pre-oxygenation with high-flow nasal cannula oxygen confirmed by electrical impedance tomography

“…The literature supports HFNC use for preoxygenation before endotracheal intubation. [ 2 ] Intubation may be difficult in obese patients, and they may require pre-oxygenation. [ 3 ] Similar to computed tomography, EIT can be used to assess regional ventilation distribution and lung volume change.…”
