Pediatric Anesthesia

A 4-year-old child weighing 16 kg is scheduled for hernia repair under general anesthesia. Assuming he was NPO for 8 hours, his total fluid deficit will be about _____ (mL):

Explanation B. Maintenance fluid requirements to replace fluid deficits accounting for a period of fasting can be calculated by the following formula. Calculation of maintenance fluid requirements Weight Hourly Fluid Requirement <10 kg 4 mL/kg 10–20 kg 40 mL + 2 mL/kg > 10 kg >20 kg 60 mL/kg + 1 mL/kg > 20 kg Thus using above formula, total fluid deficit would be 40 + (6 × 2) = 52 mL/h. Accounting for 8 hours of fasting, total fluid deficit will be 52 × 8 = 416 mL.
