    AbstractTransnasal humidified rapid-insufflation ventilatory exchange (THRIVE) can prolong apnoea time in adults. Therefore, THRIVE used for pre-oxygenation in rapid sequence induction of anaesthesia could extend safe apnoea time during prolonged laryngoscopy and intubation. In this randomised controlled trial, we compared the lowest peripheral oxygen saturation (SpO2 ) during intubation when pre-oxygenating with either traditional facemask or THRIVE. Eighty adult patients, undergoing rapid sequence induction of anaesthesia for emergency surgery, were randomly allocated to pre-oxygenation with 100% oxygen with facemask or with THRIVE. Median (IQR [range]) lowest SpO2 until 1 min after intubation was 99% (97-100 [70-100]%) for the facemask group vs. 99% (99-100 [96-100]%) for the THRIVE group (p = 0.097). Five patients (12.5%) desaturated below 93% when pre-oxygenated with the facemask vs. none in the THRIVE group (p = 0.019). There were no differences in intubation time or apnoea time between the groups. Median intubation time was 51 (34-66 [22-261]) s in the facemask group vs. 48 (38-63 [10-146]) s in the THRIVE group (p = 0.99). Median apnoea time was 109 (86-142 [37-291]) s and 116 (92-146 [63-249]) s when using facemask and THRIVE, respectively (p = 0.49). No signs of regurgitation of gastric content were detected. The data on desaturation indicate potential benefits of oxygenation with THRIVE for rapid sequence induction compared with facemask pre-oxygenation.© 2018 The Association of Anaesthetists of Great Britain and Ireland.
