The impact of preoperative carbohydrate ingestion one hour before surgery on children's preoperative anxiety and postoperative pain under ultrasound monitoring: A randomized controlled trial

J Clin AnesthPublished Randomised controlled trial

Authors' conclusion

Oral intake of 5 ml/kg of carbohydrates 1 h before surgery is safe, it can significantly improve preoperative anxiety and blood glucose fluctuations in children and reduce the incidence of perioperative adverse reactions, but it does not significantly improve postoperative pain.

Study context

Population
Children with obstructive sleep apnea hypopnea syndrome (OSAHS) undergoing adenotonsillectomy, single hospital in China, June–August 2024
Comparison
E vs C
Primary endpoint
Preoperative anxiety and postoperative pain

Primary result

As reported in the abstract

Preoperative anxiety (Modified Yale Preoperative Anxiety Scale) and postoperative pain (Wong-Baker FACES)
Preoperative anxiety significantly lower in E vs C
P < 0.05
No significant difference in postoperative pain scores between groups
P > 0.05

Further findings

Gastric antrum CSA and gastric volume (GV) (ultrasound) · after ingesting carbohydrates

CSA and GV significantly higher in E vs C
P < 0.05
No significant gastric content in either group before entering the operating room
P > 0.05

Fasting blood glucose, blood insulin, insulin resistance index · perioperative

All significantly lower in E vs C
P < 0.05

Safety

Incidence of PONV and agitation significantly lower in E vs C
P < 0.05
