Gastric Volume After Drinking 175 ml of Ice Water Prior to Gastroscopy in Healthy Adult Patients

Not Applicable

Completed

• Conditions: Fasting; Perioperative Pulmonary Aspiration
• Interventions: Other: Ice water

• Registration Number: NCT05685446
• Lead Sponsor: Vendsyssel Hospital

Brief Summary

Recommendation for fluid fasting is two hours prior to anaesthesia, however, less may be acceptable. The current study compares ingestion of 175 ml ice water prior to elective gastroscopy vs. standard fasting on gastric residual volume.

Detailed Description

Recommendations regarding fasting requirements prior to general anaesthesia is two hours for fluids. Recent research indicates that reduced fluid fasting time may be acceptable. The current study aimed to compare ingestion of 175 ml ice water 15 minutes prior to procedure compared to standardized fasting regimen on residual gastric volumes in patients receiving elective gastroscopy, as these volumes may have implications for fasting requirements.
