Immediate "sipping" vs. delayed oral fluid intake after extubation: A randomized controlled trial

Area of Science:

• Critical Care Medicine
• Perioperative Care
• Gastroenterology

Background:

• Delayed oral fluid intake post-extubation is common but often lacks evidence-based justification.
• Current practices may stem from tradition rather than clinical data.
• This study addresses the need for evidence in post-extubation fluid management.

Purpose of the Study:

• To evaluate the safety and efficacy of immediate oral fluid intake (sipping) after extubation in intensive care unit (ICU) patients.
• To determine if early sipping reduces patient thirst and discomfort.
• To assess the incidence of adverse effects associated with immediate fluid intake.

Main Methods:

• A single-center, prospective, randomized controlled trial involving 160 ICU patients meeting extubation criteria.
• Patients were randomized to either delayed fluid intake (2 hours post-extubation) or immediate sipping (up to 3 ml/kg over 2 hours).
• Thirst, discomfort, and adverse events (nausea, vomiting, aspiration) were assessed at multiple time points up to 120 minutes post-extubation.

Main Results:

• While overall thirst prevalence was similar at 120 minutes, the sipping group showed significantly greater thirst relief (11.3% vs. 1.3%, p=0.0338).
• Throat discomfort was significantly reduced in the sipping group at 90 minutes (23.8% vs. 42.5%, p=0.0118).
• Adverse effects like nausea and vomiting were rare and comparable between groups; no aspiration events occurred.

Conclusions:

• Immediate oral fluid sipping post-extubation is safe for ICU patients.
• Early rehydration improves thirst relief and reduces patient discomfort.
• Findings support challenging traditional fasting practices and implementing early oral fluid intake in post-extubation care.
