Catheters: When Are They Needed?

This post was written with Consensus AI Academic Search Engine – please read our Disclaimer at the end of this article. Catheters are medical devices used to facilitate the drainage of fluids, most commonly urine, from the body. They are essential in various medical scenarios, ranging from surgical procedures to long-term care for certain medical conditions. This article explores the circumstances under which catheters are necessary, drawing insights from recent research studies.

Post-Surgical Use

Catheters are often used post-surgery to manage urinary retention and ensure proper drainage. For instance, after hysterectomy procedures, in-dwelling catheters are typically used for 24 hours. However, studies suggest that early removal of these catheters does not increase the risk of febrile events or urinary tract infections, and it significantly reduces patient-reported pain1. Similarly, in laparoscopic inguinal hernia repairs, the use of intraoperative urinary catheters does not significantly reduce the risk of postoperative urinary retention, suggesting that their routine use may be reconsidered5.

Intravenous Therapy

In the context of intravenous (IV) therapy, catheters are crucial for administering medications and fluids. Peripheral intravenous catheters (PIVCs) are commonly used, but they often fail, leading to therapy interruptions. Midline catheters, which are longer and inserted in the upper arm, have been shown to reduce the need for frequent replacements and are associated with fewer complications, making them a preferable option for treatments extending beyond four days3 6 7.

Infection Prevention

Catheters can also play a role in preventing infections. For example, tunneled femoral catheters have been shown to reduce the risk of catheter-related infections in critically ill patients by increasing the distance between the skin entry point and the vein, thereby minimizing pathogen transfer9. Additionally, antimicrobial-impregnated catheters have been evaluated for their effectiveness in reducing catheter-associated urinary tract infections (CAUTIs) and bloodstream infections, with mixed results regarding their cost-effectiveness and clinical benefits4 10.

Home vs. Clinical Removal

The removal of urinary catheters can be managed at home or in a clinical setting. Research indicates that home removal of urinary catheters after urogynecologic surgery is non-inferior to office removal in terms of urinary retention rates. Patients who removed their catheters at home reported lower pain and higher satisfaction, suggesting that home removal could be a viable option for many patients8.

Conclusion

Catheters are indispensable in various medical settings, particularly for managing post-surgical care, facilitating long-term IV therapy, and preventing infections. The choice of catheter type and the timing of its removal should be tailored to the patient’s specific needs and the clinical context, balancing the benefits of catheter use with the potential risks and patient comfort.
