# Pediatric Fluid Calculator MCP > Pediatric Fluid Calculator uses the Holliday-Segar rule to determine precise fluid maintenance needs for children. It calculates total daily volume, sets appropriate hourly infusion rates, and provides specific electrolyte recommendations based solely on weight in kilograms. This MCP handles complex pediatric math—from 4ml/kg for the first 10kg down to 1ml/kg above 20kg—so clinicians get accurate data instantly. ## Overview - **Category:** healthcare - **Price:** Free - **Tags:** pediatrics, fluid-calculation, holliday-segar, medical-engine, nursing ## Description When you're caring for a child, getting fluid maintenance calculations wrong isn't an option. This MCP provides clinically precise tools that determine exactly how much fluid a pediatric patient needs daily and hourly. It uses the established Holliday-Segar method, which means it correctly handles weight segmentation: 4ml/kg up to 10kg, then 2ml/kg for the next 10kg block, and finally 1ml/kg for anything over 20kg. You just input the patient's weight in kilograms and get a full breakdown of their fluid requirements—total daily volume, specific hourly rates, and recommended electrolyte concentrations. By connecting this through Vinkius, your AI client accesses established medical standards without you having to switch between calculation sheets or consult multiple reference guides. It’s reliable data that goes straight into your workflow. ## Tools ### get_electrolyte_recommendation Retrieves specific concentration recommendations for key electrolytes based on the patient's body weight. ### calculate_daily_volume Calculates the total fluid volume needed over a 24-hour period and breaks down how that volume should be distributed. ### calculate_hourly_rate Determines the exact milliliter rate required for continuous IV infusion, reported per hour. ## Prompt Examples **Prompt:** ``` Calculate the daily fluid volume for a child weighing 15kg. ``` **Response:** ``` For a weight of 15kg, the total daily volume is 80ml/day. This includes 40ml for the first 10kg and 20ml for the next 5kg. ``` **Prompt:** ``` What is the hourly infusion rate for a 25kg patient? ``` **Response:** ``` The required hourly infusion rate for a 25kg patient is 104.17 ml/hour. ``` **Prompt:** ``` What are the electrolyte recommendations for an 8kg infant? ``` **Response:** ``` For an 8kg patient (Neonatal/Infant Tier), the recommended concentration is 150 mEq/L of Sodium and 75 mEq/L of Potassium. ``` ## Capabilities ### Determine total daily volume Calculates the full 24-hour fluid requirement, giving both the total milliliter count and how it should be distributed. ### Calculate hourly infusion rate Converts the required daily amount into a specific milliliters per hour rate for IV pumps. ### Get electrolyte recommendations Provides targeted concentration suggestions for key electrolytes based on the patient's weight tier. ## Use Cases ### A child's fluid needs changed overnight. The nurse needs to adjust the IV drip rate for a 12kg patient who developed dehydration. She asks her agent: 'What is the hourly infusion rate for a 12kg patient?' The system runs `calculate_hourly_rate` and immediately returns the required ml/hr, so she can safely program the pump without delay or error. ### Setting up a new drip protocol. A resident is starting a complex fluid regimen. They ask for the total daily volume for a 25kg patient. The agent runs `calculate_daily_volume`, providing not just the total ml, but also detailed distribution instructions across the day. ### Checking electrolyte balance. The pharmacist is reviewing bloodwork and needs to know if the fluid mix is right. They ask for `get_electrolyte_recommendation` for an 8kg infant. The tool provides specific mEq/L targets, allowing them to validate the order instantly. ### Comparing complex protocols. A clinician needs to compare a standard maintenance drip versus a high-output fluid regimen. They input both weights and run `calculate_daily_volume` on each, getting two distinct, comparable total ml/day figures. ## Benefits - Instantly calculate the full 24-hour fluid volume using `calculate_daily_volume`, eliminating complex, segmented manual calculations. - Get immediate IV pump rates with `calculate_hourly_rate`, converting total daily needs into precise milliliters per hour. - Avoid guessing electrolyte levels. Use `get_electrolyte_recommendation` to get weight-specific concentration suggestions for Sodium and Potassium. - Handles the tricky math of pediatric fluid dosing, automatically applying 4ml/kg (first 10kg), 2ml/kg (next 10kg), and 1ml/kg (over 20kg). - Reduces clinical friction. Instead of opening three different calculators, you run one prompt against this MCP to get all necessary data points. ## How It Works The bottom line is you get clinically accurate, multi-faceted fluid calculations in one place. 1. Enter the child's current body weight in kilograms into your AI client. 2. The MCP runs complex pediatric math, applying the Holliday-Segar formula across multiple weight segments automatically. 3. Your agent returns a set of actionable metrics: total daily volume (ml/24h), hourly infusion rates (ml/hr), and electrolyte concentration suggestions. ## Frequently Asked Questions **Does Pediatric Fluid Calculator handle adult weights for calculate_daily_volume?** No, this MCP is strictly designed for pediatrics. It uses the Holliday-Segar rule and cannot accurately calculate fluid volumes for adults; you need a different tool for that. **What if I only want to know the total daily volume?** You can run `calculate_daily_volume` by providing just the weight. This will give you the full 24-hour ml count and distribution details for your plan. **How do I get the rate needed for an IV pump?** Use `calculate_hourly_rate`. Providing the patient's weight makes sure the result is in milliliters per hour, which is exactly what infusion pumps require. **Does it help with electrolyte checks?** Yes. Running `get_electrolyte_recommendation` gives you specific concentration suggestions for key minerals like Sodium and Potassium based on the patient's weight tier. **Can I input a range of weights?** No, you must provide a single current body weight in kilograms. The calculations are based on that specific snapshot measurement.
