About this study
Official title: Blood Glucose Levels in Children During Anesthesia: Incidence of Hypoglycemia During Anesthesia Induction and Its Relationship to Preoperative Fasting
This cross-sectional study aims to investigate blood glucose levels in children during general anesthesia and explore the incidence of hypoglycemia after anesthesia induction in relation to preoperative fasting.
Blood glucose will be measured following anesthesia induction and prior to discontinuing the administration of the anesthetic agent.
Read the detailed description
This cross-sectional study aims to investigate blood glucose levels in children < 18 years during general anesthesia, and explore the incidence of hypoglycemia after anesthesia induction in relation to preoperative fasting.
The purpose is to evaluate whether guidelines for shortening the preoperative fasting period of children at our hospital have resulted in a shorter fasting duration and prevalence of low blood glucose levels during anesthesia induction. Also to shed light on blood glucose levels during general anesthesia and its correlation with intravenous fluid management and administration of steroidal anti-emetics.
Blood glucose sampling will be obtained and measured following anesthesia induction and prior to discontinuing the anesthetic agent. If general anesthesia lasts longer than one hour, additional blood glucose analysis will be conducted one hour after the first measurement.

What does the primary outcome measure?
Serum blood glucose level (time frame: Immediately/within five minutes after anesthesia induction and prior to discontinuing the anesthesia administration.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Apr 2025.
