Before premedication in renal disease, how long should water be offered?

• A. 30 minutes
• B. 1 hour
• C. 2 hours
• D. 4 hours

Answer: (B)

Water is a clear fluid that empties from the stomach relatively quickly. In renal disease, we aim to balance keeping the patient hydrated with minimizing gastric volume at the time of premedication and airway management. Offering water about an hour before premedication allows enough time for gastric emptying, reducing the risk of aspiration during sedation or induction, while still helping prevent dehydration or electrolyte shifts that can be problematic in renal impairment. If offered too soon, there may be more gastric contents; if delayed longer than an hour, the patient may become thirsty or mildly dehydrated without added safety benefit. Hence, one hour before premedication is the best compromise.
