Preoperative starvation and plasma glucose concentrations in children undergoing outpatient anaesthesia
Insights
Pediatric outpatient anesthesia did not cause hypoglycemia in young children after 8 hours of fasting. This study suggests findings from inpatient studies may not apply to young outpatients.
Area of Science:
- Pediatric Anesthesiology
- Pediatric Endocrinology
Background:
- Hypoglycemia is a risk in pediatric patients undergoing anesthesia due to fasting.
- Previous studies on pediatric anesthesia and glucose levels have primarily focused on inpatients.
Purpose of the Study:
- To investigate plasma glucose concentrations in children under 5 years undergoing outpatient anesthesia.
- To determine if prolonged fasting in pediatric outpatients leads to hypoglycemia.
Main Methods:
- Thirty-one children under 5 years old were studied.
- Plasma glucose levels were measured post-induction of anesthesia in an outpatient setting.
Main Results:
- The mean plasma glucose concentration was 4.70 mmol/L.
- No patients exhibited plasma glucose levels below 2.8 mmol/L, even after at least 8 hours of starvation.
- The lack of hypoglycemia in this cohort remains unexplained.
Conclusions:
- Pediatric outpatient anesthesia does not appear to induce hypoglycemia in young children, even after prolonged fasting.
- Findings from studies on young inpatients may not be generalizable to young outpatients.
- Further research is needed to understand the mechanisms preventing hypoglycemia in this population.
Abstract:
Thirty-one children aged less than 5 years were studied while attending hospital for anaesthesia as outpatients. Plasma glucose concentrations were measured after the induction of anaesthesia. The mean plasma glucose concentration was 4.70 mmol litre-1. No patients had a plasma glucose concentration less than 2.8 mmol litre-1, despite at least 8 h of starvation. This is unexplained. It is suggested that the conclusions drawn from studies made in young inpatients may not be applicable to young outpatients.
