Final answer:
TKVO or maintenance infusion rates for pediatric patients between 2 to under 12 years of age are calculated based on the child's weight and can be around 10-30 mL/hr. It is important to consult a physician or follow hospital protocols to determine the exact volume for a specific patient.
Step-by-step explanation:
The term TKVO (to keep vein open), also known as maintenance infusion, refers to the minimum rate at which an intravenous fluid is administered to maintain patency of the vein. For pediatric patients between the ages of 2 years to less than 12 years, the maintenance infusion volume varies. It is generally calculated based on the child's weight using the 4-2-1 rule: 4 mL/kg/hr for the first 10 kg of body weight, plus 2 mL/kg/hr for the next 10 kg, and then 1 mL/kg/hr for each additional kilogram. However, the TKVO rate is typically much lower than the maintenance infusion requirements and can be around 10-30 mL/hr, depending on the size of the catheter and the patient's vein condition. It's important to always consult with a physician or follow hospital protocols to determine the exact volume required for a specific patient.
