Application of THRIVE in Burn Children With Suspected Difficult Airway

In order to improve intubation conditions in burn children, our aim is to investigate the efficacy of transnasal humidified rapid-insufflation ventilatory exchange technique（THRIVE) in children aged between 0 and 18 years who with head, face, and neck injuries by fire, scalding, chemical, electric,explosions, and others. We hypothesise that THRIVE increases first attempt success without hypoxemia in intubation of children and compared with routine practice.

Does the THRIVE can prolong apnoea time and delay the onset of desaturation to increase the success rate of the first tracheal intubation without desaturation?

Researchers will compare THRIVE group with Routine care group to see successful intubation on the first attempt without desaturation.

Participants will received intravenous anesthesia induction, followed by 2-3 minutes preoxygenation, before intubation, the mask was removed from the children's face and a THRIVE nasal plug was placed. During intubation, the Routine care group had no oxygen supply,and the THRIVE group will be maintained throughout the apnoeic period with selected flow rates during intubation attempts.
