Hypoxaemia during paediatric dental anaesthesia in the community
1Department of Anaesthesia, Blackburn Royal Infirmary.
Insights
This study found a 12% incidence of hypoxemia during pediatric dental anesthesia, highlighting the need for careful oxygen saturation monitoring in children. The findings support recommendations for enhanced monitoring protocols.
Area of Science:
- Anesthesiology
- Pediatric Dentistry
- Critical Care Medicine
Background:
- Hypoxemia during pediatric dental anesthesia is a significant concern.
- Previous studies indicated varying incidences, prompting reviews like the Poswillo report.
- Standardized monitoring protocols are crucial for patient safety.
Purpose of the Study:
- To measure the incidence of hypoxemia in children undergoing dental anesthesia.
- To evaluate the necessity of monitoring recommendations from the Poswillo report.
- To assess oxygen saturation trends during pediatric dental procedures.
Main Methods:
- A study of 50 ASA grade 1 children (ages 2-16) undergoing dental extractions.
- Standard anesthesia: 30% oxygen, 70% nitrous oxide, supplemented with halothane.
- Continuous oxygen saturation monitoring using pulse oximetry.
Main Results:
- A 12% incidence of hypoxemia was recorded.
- 32% of patients experienced a 5% fall in oxygen saturation from baseline.
- Hypoxemia occurred during both operative and recovery phases.
Conclusions:
- The observed hypoxemia incidence, though lower than some prior studies, necessitates vigilant monitoring.
- Findings fully support the monitoring recommendations outlined in the Poswillo report.
- Continuous pulse oximetry is essential for detecting hypoxemia in pediatric dental anesthesia.
Abstract:
The object of this paper is to measure the incidence of hypoxaemia during paediatric dental anaesthesia in the community and thus support or refute the recommendations for monitoring in the Poswillo report. Fifty unpremedicated children, ASA grade 1, between the ages of 2 and 16 years undergoing general anaesthesia for teeth extraction were studied. Patients were anaesthetised with a standard anaesthetic which consisted of 30% oxygen in 70% nitrous oxide and supplemented with halothane. A pulse oximeter was used to measure the oxygen saturation continuously. A 12% incidence of hypoxaemia was recorded and a 32% incidence of a 5% fall in the oxygen saturation from the baseline. Three children became hypoxaemic during the operative period and three during the recovery period. Although the incidence of hypoxaemia in this study was significantly lower than in previous studies, the incidence suggests that careful monitoring is essential and the recommendations that have been put forward in the Poswillo report are fully justified.
