In the press, the JAMA: High-Flow Nasal Cannula System, Not Just Another Nasal Cannula introduced the application of high-flow nasal cannula (HFNC) as a choice for preoxygenation to reduce apnea duration. In our study, we used HFNC broadly and extended its advantage by applying it to a patient with severe pulmonary hypertension who received vertebroplasty surgery under high-flow nasal cannula.
An 86-year-old woman had been suffering from back pain for months and had a compression fracture of T10. The surgeon suggested vertebroplasty to relieve her painful condition. However, she had hypertension and diabetes with limited functional activity. The echocardiogram revealed severe tricuspid valve regurgitation with a pulmonary atrial pressure of 57 mmHg and an ejection fraction of 53%. She was put on treatment with apixaban 5 mg, spironolactone 25 mg, amlodipine 5 mg, valsartan 80 mg, bisoprolol 2.5 mg, amiodarone 400 mg, and digoxin 0.125 mg. Her vital signs showed a heart rate of 120–132 beats/min with atrial fibrillation, non-invasive blood pressure of 128/74 mmHg, and SpO2 84% in the operating room. Her ASA physical status was III. The surgeon was informed of the situation and managed it with adequate local anesthetics before the incision to decrease the intravenous anesthetic dose usage. She was placed in the prone position wearing the high-flow nasal cannula as preoxygenation until SpO2 97% under Optiflow THRIVE™ HFNO at 35 L/min. On induction with lidocaine 40 mg and i.v. propofol, we gave a target control infusion with continuous propofol until she was not responsive to verbal commands and closed her eyes. During the surgery (40 min), the patient was prone under the HFNC, and SpO2 was kept above 95%. During the operation, the mean blood pressure stayed above 70 mmHg and SpO2 stayed above 95%. After the surgery, the patient recovered under temporary HFNC in the postanesthesia care unit.
There are two key considerations for maintaining adequate oxygenation in this patient. First, pulmonary hypertension with right-sided heart failure makes the patient not tolerate room air, including the apnea time under intravenous anesthetics. Both desaturation and carbon dioxide retention could worsen her pulmonary hypertension and add further load on her heart. The HFNC provides continuous positive airway pressure, and because of insufflation ventilatory, carbon dioxide clearance occurs through gaseous mixing which flushes the dead spaces. Some studies use this advantage on pulmonary hypertension patients during bronchoscopy.
Second, the prone position made the ventilation difficult. It is impractical or poorly tolerated to recruit the lung with high airway pressure when it is desaturated while in the prone position, especially for older patients with a stiff cervical spine. However, the prone position may provide an alternative way to recruit the dorsal lung regions without high ventilatory pressures,, which could induce superior alveolar ventilation. No matter which position is used, we should always refer to the rescue plan in situations such as desaturation or unstable vital signs, even while under HFNC.
There were no available clinical trials in the literature relating to the use of HFNC in managing pulmonary hypertension patients under the prone position with intravenous anesthetics and without intubation. As Vella et al. mentioned, the HFNC system could be routinely integrated into rescue algorithms for possible events of respiratory deterioration. Here, we provide practical clinical and surgical situations to use HFNC innovatively.
