No results posted yet for this study

Summary

This single-center randomized controlled trial aims to evaluate whether intraoperative monitoring using the Oxygen Reserve Index (ORI) reduces the incidence of postoperative atelectasis, as assessed by lung ultrasound (LUS), in adult patients undergoing elective robotic surgery under general anesthesia.

Conditions

  • Atelectasis
  • Lung Ultrasonography Score
  • Hyperoxia

Interventions

PROCEDURE

Peripheral Oxygen Saturation (SpO₂) Group

FiO₂ adjusted based on pulse oximetry to maintain SpO₂ ≥98%

PROCEDURE

Peripheral Oxygen Saturation and Oxygen Reserve Index (SpO₂-ORI) Group

FiO₂ adjusted using both SpO₂ and ORI to maintain ORI between 0-0.3
