NCT05912543

Brief Summary

The purpose of this prospective randomized controlled trial is to determine whether using the Oxygen Reserve Index can prevent hyperoxemia in pediatric patients receiving single-lung ventilation. Participants will have their FiO2 adjusted in a prescribed manner based on the arm to which they are assigned. The researchers will compare whether blood oxygen levels were lower in the ORI group.

Conditions

Outcome Measures

Primary Outcomes (1)

  • The incidence of moderate to severe hyperoxemia in arterial blood gas analysis at T2 (30 minutes after one lung ventilation)

    arterial oxygen content over 200

    30 minutes after initiation of one-lung ventilation

Secondary Outcomes (4)

  • average Oxygen Reserve Index value

    during one lung ventilation

  • time-weighted average inspired oxygen fraction

    during one lung ventilation

  • incidence of hypoxemia

    perioperative period

  • incidence of perioperative complications

    perioperative period

Study Arms (2)

Conventional arm

NO INTERVENTION

Moderate hyperoxia as determined by T1 arterial blood gas. For moderate hyperoxemia (PaO2 \> 300 mmHg), reduce the inspired oxygen concentration to 80% and for severe hyperoxemia to 70%. In the situation of hypoxia, where the peripheral oxygen saturation decreases to less than 95% even in 100% of FiO2, the following treatment is indicated: Fluid administration, inotropes administration (dopamine), alveolar recruitment, return to two-lung ventilation, and application of continuous positive airway pressure.

ORI arm

EXPERIMENTAL

Target ORi™ of 0.15, check the ORi™ every 5 minutes and adjust the inspired oxygen concentration in 5% increments. If the ORi™ decreases to less than 0.15, treat it in the same way as if hypoxia occurred in the conventional group.

Procedure: Titration of FiO2

Interventions

The inhaled oxygen concentration after one-lung ventilation will be treated by the group.
