Insights
Postanesthetic recovery (PAR) scores in children do not reliably indicate oxygen saturation (SaO2) levels. Supplemental oxygen or SaO2 monitoring is recommended for all pediatric patients after anesthesia.
Area of Science:
- Pediatric Anesthesiology
- Postoperative Care
- Respiratory Physiology
Background:
- Assessing postanesthetic recovery (PAR) in children is crucial for safe discharge.
- Oxygen saturation (SaO2) is a key indicator of respiratory function post-anesthesia.
- The relationship between PAR scores and SaO2 in pediatric patients requires further clarification.
Purpose of the Study:
- To investigate the correlation between postanesthetic recovery (PAR) scores and oxygen saturation (SaO2) in children.
- To determine if PAR scores can predict hypoxemia in the recovery room.
- To evaluate the effectiveness of PAR scores in guiding oxygen supplementation decisions.
Main Methods:
- Studied 81 ASA PS I unpremedicated infants and children.
- Recorded oxygen saturation (SaO2) and modified Aldrete PAR scores at intervals post-anesthesia.
- Administered supplemental oxygen to patients with SaO2 < 95%.
Main Results:
- No significant difference in SaO2 levels (<95% vs. >=95%) between low (<=6) and high (7-10) PAR score groups across age ranges.
- The increase in SaO2 after oxygen supplementation did not correlate with higher PAR scores.
- Hypoxemia was observed in children during recovery from anesthesia.
Conclusions:
- Postanesthetic recovery (PAR) scores in children do not reliably indicate oxygen saturation (SaO2) levels.
- Wakefulness, as measured by PAR scores, is insufficient to determine the need for oxygen supplementation.
- Continuous SaO2 monitoring and/or supplemental oxygen are recommended for all children recovering from anesthesia.
Abstract:
The correlation between the degree of postanesthetic recovery (PAR) in children as measured by a modified Aldrete scoring system and oxygen saturation (SaO2) was studied. Eighty-one ASA PS I unpremedicated infants and children were studied. Oxygen saturation and PAR scores were recorded on arrival in the recovery room, then at 5-minute-intervals. Patients with SaO2 less than 95% were given supplemental oxygen. The proportion of children with SaO2 less than 95% and greater than or equal to 95% was not significantly different among patients with low PAR scores (less than or equal to 6) and those with high scores (7-10) in any age group. Similarly, the magnitude of SaO2 increase after oxygen supplementation did not seem to correlate with increasing wakefulness; i.e., higher PAR scores. It is concluded that children recovering from anesthesia can become hypoxemic in the recovery room. The degree of wakefulness as measured by a PAR score cannot be used to establish an end point for oxygen supplementation. Oxygen supplementation and/or SaO2 monitoring are recommended in all children recovering from anesthesia.
