Learn how to safely use Medline Active Critical Care liquid protein as a tube feeding supplement, including preparation, administration, and storage tips.
Quick Answer
To use Medline Active Critical Care liquid protein for enteral feeding, verify tube placement, warm the supplement to room temperature, and administer slowly via syringe or feeding pump, then flush the tube with water.
Why Choose a High-Protein Liquid Supplement
Patients with critical illness or wounds often have increased protein needs that standard formulas may not meet. A concentrated liquid protein supplement like Medline Active Critical Care provides 18 grams of protein per 1 oz. serving, making it easier to boost intake without adding large volumes of fluid.
This supplement combines hydrolyzed collagen and whey protein, which are rapidly absorbed and support tissue repair. The added arginine, zinc, and vitamin C specifically target wound healing, which is a common concern in critical care settings.
Important Considerations Before Use
This product is not a complete enteral formula. It is designed to supplement, not replace, a balanced tube feeding regimen. Always consult a healthcare provider to determine the appropriate amount and rate for your specific needs.
Because the product is shelf-stable, it does not require refrigeration until opened. Once opened, follow the storage guidelines on the label to prevent contamination.
Step-by-Step Administration Guide
- Verify tube placement: Confirm the feeding tube is correctly positioned per your facility's protocol. Check gastric residual if applicable, and ensure the tube is not clogged. Never proceed without confirming placement to avoid aspiration.
- Prepare the supplement: Shake the bottle well, then allow the liquid to reach room temperature. Cold liquid can cause cramping or discomfort. Do not microwave or heat the supplement—this can destroy nutrients and create hot spots.
- Draw the prescribed amount: Use a clean syringe to draw up the exact volume ordered by the clinician. Avoid touching the tip of the syringe to keep it sterile. Double-check the dose with another caregiver if possible to prevent errors.
- Administer slowly: Attach the syringe to the feeding tube and deliver the supplement gradually. A typical rate is 30-60 mL per minute unless otherwise specified. Rapid administration can cause nausea, vomiting, or dumping syndrome—slow down if the patient shows discomfort.
- Flush the tube: After the supplement is fully administered, flush the tube with 15-30 mL of water (or as ordered) to clear residual liquid and prevent clogging. Always flush before and after medications to maintain tube patency.
- Store leftovers properly: If the bottle is not finished, cap it and refrigerate immediately. Use within 24 hours or discard per label instructions. Never leave opened supplement at room temperature for more than 2 hours—bacteria can grow rapidly.
