    AbstractHi-flow nasal oxygen (HFNO) has revolutionized tubeless field anesthesia for airway surgery without the complications of jet ventilation. However, its use in third trimester parturients undergoing open airway surgery has been limited to an apneic technique (Transnasal Humidified Rapid-Insufflation Ventilatory Exchange [THRIVE]) in current publications. We used SponTaneous Respiration using IntraVEnous anesthesia and Hi-flow nasal oxygen (STRIVE Hi) in the management of tracheal dilatation in a near-term parturient at 36 weeks of gestation. Transferring this established protocol for spontaneous ventilation in the obstructed airway onto near-term parturients may mitigate the risks of apnea with hypercapnia, subsequent acidosis, and potential fetal harm.Copyright © 2021 International Anesthesia Research Society.
