[Postoperative arterial oxygen saturation in children].

Area of Science:

• Anesthesiology
• Pediatric Critical Care
• Medical Device Technology

Background:

• Perioperative monitoring of arterial oxygen saturation is crucial in pediatric patients.
• Assessing the efficacy and reliability of different pulse oximetry devices is essential for patient safety.
• Understanding positional effects on oxygenation during postoperative transport is clinically relevant.

Purpose of the Study:

• To compare the Nellcor N-100 and N-200 pulse oximeters for monitoring arterial oxygen saturation in pediatric patients.
• To evaluate oxygen saturation levels during postoperative transportation.
• To assess the impact of patient positioning on oxygen saturation during transport.

Main Methods:

• Arterial oxygen saturation was monitored in 46 pediatric patients (ASA physical status I-II) using Nellcor N-100 and N-200 devices.
• Oxygen saturation was assessed during perioperative periods and postoperative transportation.
• Patients underwent a trial of spontaneous breathing with varying oxygen fractions prior to transfer.

Main Results:

• A statistically significant, yet clinically acceptable, desaturation was observed during postoperative transportation.
• The Nellcor N-200 demonstrated significantly fewer motion artifacts compared to the Nellcor N-100.
• No significant difference in arterial oxygen saturation was found between the lateral and supine positions.

Conclusions:

• The Nellcor N-200 offers improved performance regarding motion artifacts compared to the N-100 for pediatric oxygen saturation monitoring.
• Spontaneous breathing trials with supplemental oxygen can maintain acceptable saturation levels during postoperative transport.
• The lateral position is recommended for postoperative transportation of pediatric patients to ensure optimal oxygenation.
