Nasogastric Fluid Administration
Nasogastric (NG) fluid administration involves the delivery of fluids, electrolytes, or enteral nutrition directly into the stomach through a flexible tube inserted via the nasal passage. This method is highly effective for treating moderate dehydration (especially in pediatric gastroenteritis when oral rehydration fails) and for providing long-term nutritional support.
Dosage by Body Weight
Dosage, rate, and fluid composition must be highly individualized based on the clinical indication (rehydration vs. maintenance nutrition), hydration status, and renal function. For enteral rehydration therapy, a standard rate of 15 to 20 mL/kg/hour of Oral Rehydration Solution is typically administered.
