NCT03892408

Brief Summary

The aim of this study is to evaluate the effect of high-flow nasal cannula oxygen administration on apnea in patients undergoing general anesthesia with rigid bronchoscopy compared with standard anesthesia methods.

Outcome Measures

Primary Outcomes (1)

  • the lowest oxygen saturation

    the lowest value of oxygen saturation measured percutaneously at extremity.

    apnea period during the rigidbroscopic procedure/surgery

Secondary Outcomes (5)

  • Hypoxia occurs the first time

    intraoperative (The time taken to reach the point at which peripheral oxygen saturation fell below 90 for the first time immediately after the onset of apnea)

  • End-tidal carbon dioxide partial pressure

    Intraoperative (end-tidal CO2 partial pressure after 3 consecutive breaths after intubation or insertion of laryngeal mask following end of apnea)

  • Arterial oxygen / carbon dioxide partial pressure

    shortly before start of apnea (within 30 seconds)

  • Arterial oxygen / carbon dioxide partial pressure

    shortly after end of apnea (within 30 seconds)

  • hypoxemia related surgical interruptions

    4) hypoxemia related surgical interruptions during apneic period

Study Arms (2)
