How to Select a Proper Suction Catheter for Patients?

Suctioning helps patients clear airway secretions effectively and prevents them from breathing problems. And the correct suction catheter size is a key factor in effective suctioning. Because the wrong size can lead to tracheal damage, mucosal injury, or even blockage of the tracheal tube, deprivation. However, mastering the tips for choosing the right suction catheter can minimize risks and improve treatment outcomes. In this article, you can get the complete guide, let's get started.

What is a Suction Catheter?

The suction catheter is widely used in hospitals, clinics, and even home care settings. It consists of three parts, the catheter, suction control device, and connector. It aims to remove secretions, blood, or other fluids from a patient's airway or respiratory tract.

The catheter connects to a suction source through its connector and is used to suction out mucus and secretions from the tracheal tube. It's a long, soft tube usually made of plastic or rubber. One end is connected to suction equipment like a vacuum pump, and the other end is inserted into the patient's mouth, nose, or tracheal tube to clear the airway.

Important: Suction catheters are single-use, sterile products and should never be reused.

Why is Proper Suction Catheter Important?

Using the wrong size suction catheter can lead to several problems. For example, a small catheter may not remove airway secretions effectively. And may leave behind secretions, increasing the risk of airway blockage and infection, finally worsening the patient's breathing. On the other hand, a too one can take up too much airway space during suctioning, reducing airflow and causing oxygen deprivation. It may also cause more friction against the airway walls, increasing the risk of mucosal injury or bleeding. So, choosing the proper catheter ensures effective airway clearance while minimizing the risk of complications.

How to Choose a Proper Suction Catheter for Patients?

Calculating the catheter size is a crucial step in choosing the right suction catheter for the patient. It begins with knowing the tracheal tube size. Here are three common formulas to help you calculate the appropriate suction catheter size:

Catheter Size Calculation

Formula 1: Tracheal tube internal diameter (ID) × 3 ÷ 2, then select the next largest French size (Fr).

Example: If the tracheal tube ID is 8 mm, the calculation is 8 × 3 ÷ 2 = 12. So, choose the next largest size, which is a 14Fr suction catheter.

Formula 2: Tracheal tube internal diameter (ID) × 2, then select the next smaller French size (Fr).

Example: If the tracheal tube ID is 8 mm, the calculation is 8 × 2 = 16. So, choose the next smaller size, which is a 14Fr suction catheter.

Formula 3: Tracheal tube internal diameter (ID) × 2 - 2.

Example: If the tracheal tube ID is 8 mm, the calculation is 8 × 2 - 2 = 14. So, use a 14Fr suction catheter.

You can use any of these formulas to help determine the correct size for your patient’s tracheal tube.

Material

Some patients may have sensitivities or allergies to certain materials. The catheter should be made of a non-toxic, patient-friendly material. It should also be soft enough to reduce mucosal damage and allow for easy maneuvering.

Catheters with Side Holes vs. Without Side Holes

Suction catheters with side holes are generally more effective because they are less likely to get blocked by secretions. Larger side holes are typically more efficient.

Patient Age and Gender

Infants: Use a 5Fr - 8Fr

Children: Use a 6Fr - 10Fr

Adults: Use a 12Fr - 16Fr

Catheter Length

Suction catheters typically range from 30 to 50 cm in length. Must choose the right length according to the patient's airway size, it can ensure clear necessary area.

Conclusion

Selecting the right suction catheter ensures patient safety and effective airway clearance. Through proper size calculation formulas, considering the catheter material, and the patient's age and sex, your patients can get good care while reducing the risk of airway blockage, oxygen deprivation, or mucosal damage. Finally, remember to always prioritize the patient's comfort and safety, and make sure to use high-quality single-use catheters.
