Pediatric IV Sets with Burette: Complete Usage Guide for Safe Infusion Therapy

Pediatric IV Sets with Burette: Complete Usage Guide for Safe Infusion Therapy

Pediatric IV sets with burette chambers, also called volumetric chambers or graduated chambers, are specially designed intravenous administration sets for delivering precise fluid volumes to infants and children. These sets include a measured chamber that holds a specific amount of fluid, reducing the risk of fluid overload and allowing accurate medication administration in pediatric patients.

Purpose and Clinical Applications

Pediatric IV sets with burette chambers serve critical functions in pediatric care:

  • Precise Volume Control: The burette chamber holds typically 100-150 ml of fluid, allowing healthcare providers to measure and deliver exact amounts
  • Prevention of Fluid Overload: Limits the volume of fluid that can enter the patient, even if the IV bag is left unattended
  • Medication Dilution: Provides a chamber to dilute concentrated medications to appropriate pediatric doses
  • Intermittent Infusions: Facilitates scheduled antibiotic or medication administration without changing the entire IV setup
  • Multiple Medication Delivery: Allows sequential administration of different medications through the same IV line

Common Healthcare Settings

  • Pediatric hospital wards and intensive care units
  • Neonatal intensive care units (NICU)
  • Emergency departments treating children
  • Pediatric operating rooms and recovery areas
  • Outpatient infusion centers
  • Home healthcare for children requiring IV therapy

Types of Pediatric IV Sets

Type Drop Factor Best Used For
Microdrip with Burette 60 drops/ml Neonates, infants, and small children requiring very precise flow control
Standard Burette Set 15-20 drops/ml Older children and adolescents when moderate precision is needed
Vented Burette Set 60 drops/ml Used with non-vented glass bottles (less common now)
Non-vented Burette Set 60 drops/ml Used with collapsible plastic IV bags (most common)
Key Point: Microdrip sets (60 drops/ml) are preferred for pediatrics because the flow rate in ml/hour equals the drops per minute, making calculations simpler and more accurate.

Components of a Pediatric IV Set with Burette

  • Spike: Pierces the IV fluid bag or bottle
  • Air Vent: Present on vented sets to allow air entry (close when not needed)
  • Burette Chamber: Graduated transparent chamber (usually 100-150 ml capacity)
  • Drip Chamber: Shows individual drops for flow rate monitoring
  • Flow Regulator/Clamp: Controls the infusion rate
  • Injection Port: Located on burette for adding medications
  • Tubing: Connects all components to the patient
  • Luer Lock/Slip Connector: Attaches to the IV catheter
  • Filter (optional): Some sets include inline filters

Step-by-Step User Guide

Preparation

  1. Wash hands thoroughly and use appropriate personal protective equipment
  2. Check the prescription for correct fluid type, volume, rate, and any medications ordered
  3. Verify patient identity using at least two identifiers
  4. Inspect the IV set packaging for damage or expiration date
  5. Check the IV fluid bag for clarity, expiration, and correct solution
  6. Gather all necessary supplies: IV pole, tape, antiseptic wipes, gloves

Setting Up the IV Set

  1. Remove the IV set from sterile packaging without contaminating the spike or patient connector
  2. Close all clamps on the tubing before connecting to the fluid bag
  3. Remove the protective cover from the IV bag port and the spike
  4. Insert the spike firmly into the IV bag port using a twisting motion
  5. Hang the IV bag on the IV pole at appropriate height (usually 75-90 cm above the insertion site)
  6. If using a vented set with a plastic bag, ensure the air vent is closed

Priming the Burette Chamber

  1. Squeeze the drip chamber gently to fill the burette chamber to the desired level (usually 50-100 ml initially)
  2. Open the clamp between the burette and the drip chamber below it
  3. Allow fluid to flow through the entire tubing until all air bubbles are removed
  4. Fill the lower drip chamber to about one-third to half full
  5. Close the lower clamp once tubing is completely primed
  6. Check the entire length of tubing for air bubbles and tap gently to remove them
Important: Never allow air to enter the patient's IV line. Always ensure complete priming before connecting to the patient.

Calculating and Setting Flow Rate

Basic Formula for Microdrip Sets (60 drops/ml):
Drops per minute = ml per hour
Example: If ordered rate is 25 ml/hour, set to 25 drops/minute
  1. Calculate the required drops per minute based on the prescribed ml/hour
  2. Open the flow regulator clamp gradually
  3. Count the drops falling in the drip chamber for one full minute
  4. Adjust the clamp until the correct drop rate is achieved
  5. Recheck the rate after 5 minutes to ensure it remains stable

Adding Medications to the Burette

  1. Verify the medication order: correct drug, dose, route, and time
  2. Prepare the medication using aseptic technique
  3. Close the clamp above the burette to stop fluid flow from the bag
  4. Fill the burette with the prescribed amount of IV fluid (typically 20-50 ml for medication dilution)
  5. Clean the medication port on the burette with antiseptic
  6. Inject the medication into the burette chamber through the port
  7. Gently rotate or invert the burette to mix the medication thoroughly
  8. Label the burette with medication name, dose, and time
  9. Open the lower clamp and adjust the flow rate as prescribed
  10. Monitor the patient during medication infusion

Monitoring During Infusion

  • Check the IV site every 1-2 hours for signs of infiltration or phlebitis
  • Verify the flow rate regularly (at least every hour)
  • Monitor the fluid level in the burette chamber
  • Document fluid intake and remaining volume
  • Observe the patient for adverse reactions, especially during medication infusions
  • Ensure the IV site is secure and the child is comfortable

Safety Precautions and Potential Dangers

Critical Safety Warnings

  • Fluid Overload: Even with a burette, monitor total fluid intake carefully, especially in neonates and infants with limited fluid tolerance
  • Air Embolism: Always ensure complete priming and check for air bubbles. Air in IV lines can be fatal
  • Medication Errors: Double-check all medications, doses, and dilutions. Pediatric dosing requires extreme precision
  • Infiltration: Extravasation of IV fluids or medications into surrounding tissue can cause tissue damage
  • Infection Risk: Maintain strict aseptic technique to prevent bloodstream infections

Important Precautions

  • Never leave the clamp above the burette open when unattended unless intentionally refilling
  • Do not use the same burette chamber for incompatible medications without flushing thoroughly
  • Replace IV sets according to institutional policy (typically every 72-96 hours)
  • Use appropriate catheter size for the child's age and vein size
  • Secure the IV line properly to prevent accidental dislodgement by active children
  • Keep the IV bag higher than the burette and the burette higher than the patient
  • Never inject medications directly into the patient line without proper dilution
  • Check for drug incompatibilities when administering multiple medications
  • Monitor electrolyte levels when administering prolonged IV therapy

Signs of Complications to Watch For

Complication Signs to Observe
Infiltration Swelling, coolness, pallor at IV site, slowed infusion rate, discomfort
Phlebitis Redness, warmth, pain along vein, hardened vein
Infection Fever, redness, purulent discharge at insertion site
Fluid Overload Rapid weight gain, edema, difficulty breathing, increased blood pressure
Allergic Reaction Rash, itching, difficulty breathing, rapid heart rate

Frequently Asked Questions

Q: Why is a burette chamber necessary for children but not always for adults?
A: Children, especially infants and neonates, have much smaller blood volumes and limited ability to handle excess fluids. The burette limits the maximum volume that can accidentally infuse, preventing potentially fatal fluid overload.
Q: How often should the fluid in the burette be refilled?
A: This depends on the infusion rate and volume ordered. Generally, refill when the chamber is nearly empty or before administering scheduled medications. Never allow the chamber to run completely dry to avoid air entering the line.
Q: Can I use the same burette set for different medications?
A: Yes, but you must flush the chamber thoroughly with IV fluid between incompatible medications. Check drug compatibility charts. Some medications may require a dedicated line.
Q: What is the difference between microdrip and macrodrip?
A: Microdrip sets deliver 60 drops per milliliter, while macrodrip sets deliver 10-20 drops per milliliter. Microdrip provides more precise control needed for pediatric patients.
Q: How long can an IV set with burette remain in use?
A: Most guidelines recommend changing IV sets every 72-96 hours to reduce infection risk. Sets used for blood products or lipid emulsions should be changed more frequently (24 hours). Always follow your institution's protocol.
Q: What should I do if air bubbles appear in the tubing?
A: Stop the infusion immediately. Close the clamp nearest to the patient. Tap the tubing gently to move bubbles upward toward the drip chamber. Open the clamp briefly to let bubbles rise into the chamber. Never allow air to reach the patient.
Q: Can parents or caregivers operate these IV sets at home?
A: Only with proper training from healthcare professionals. Home IV therapy requires comprehensive education on setup, monitoring, troubleshooting, and recognizing complications. A home health nurse usually provides supervision.
Q: Why does the IV sometimes stop dripping?
A: Common causes include: kinked tubing, clamp accidentally closed, infiltration, catheter against vein wall, or empty burette chamber. Check each component systematically. Never force fluid through if resistance is felt.
Q: Is the burette chamber reusable?
A: No. Pediatric IV sets with burette chambers are single-use, disposable medical devices. Never attempt to clean and reuse them due to infection risk and loss of sterility.
Q: What temperature should IV fluids be?
A: IV fluids should generally be at room temperature (20-25 degrees Celsius). Cold fluids can cause discomfort and hypothermia in small children. Warmed fluids may be used in specific situations but require special warming devices.
