“…Nevertheless, those conclusions cannot be prescinded from the consideration that respiratory mechanics differs significantly between paralyzed and unparalyzed states. With paralysis, dead space gas mixing and microventilation induced by pharyngeal pressure variations are inevitably altered [55]. However, a recent five-arm RCT [56] observed that differing flow rates of humidified 100% oxygen during apnea induced comparable arterial CO 2 increases, thus questioning the existence of an additional ventilatory effect attributable to HFNOT [57].…”

Background: Noninvasive respiratory support (NRS), including high-flow nasal oxygen therapy (HFNOT), noninvasive ventilation (NIV) and continuous positive airway pressure (CPAP), are routinely used in the perioperative period. Objectives: This narrative review provides an overview on the perioperative use of NRS. Preoperative, intraoperative, and postoperative respiratory support is discussed, along with potential future areas of research. Results: During induction of anesthesia, in selected patients at high risk of difficult intubation, NIV is associated with improved gas exchange and reduced risk of postoperative respiratory complications. HFNOT demonstrated an improvement in oxygenation. Evidence on the intraoperative use of NRS is limited. Compared with conventional oxygenation, HFNOT is associated with a reduced risk of hypoxemia during procedural sedation, and recent data indicate a possible role for HFNOT for intraoperative apneic oxygenation in specific surgical contexts. After extubation, “preemptive” NIV and HFNOT in unselected cohorts do not affect clinical outcome. Postoperative “curative” NIV in high-risk patients and among those exhibiting signs of respiratory failure can reduce reintubation rate, especially after abdominal surgery. Data on postoperative “curative” HFNOT are limited. Conclusions: There is increasing evidence on the perioperative use of NRS. Use of NRS should be tailored based on the patient’s specific characteristics and type of surgery, aimed at a personalized cost-effective approach.

The administration of deep brain stimulation (DBS) in patients with Parkinson's disease is commonly carried out with the patient in an awake state with conscious sedation. However, maintaining the airway and preventing desaturation can be challenging during the procedure. High-flow nasal cannula (HFNC) has been deemed to be a safe option for providing respiratory support in such patients, affording multiple benefits. We report the case of a 48-year-old male patient with Parkinson's disease who underwent DBS, during which HFNC was employed for respiratory support. The patient tolerated the HFNC well, and the procedure was conducted without any complications related to respiratory function.
