Antibiotic Impregnated EVD Systems in Neurosurgery
External Ventricular Drainage (EVD) applications in neurosurgery are vital for hydrocephalus treatment and intracranial pressure control. However, the biggest disadvantage of this critical intervention is catheter related infections. Problems such as ventriculitis or meningitis prolong the patient’s hospital stay, increase treatment costs, and increase the severity of the disease. It may not always be possible to prevent bacterial colonization on the surface of traditional silicone catheters. At this stage, antibiotic impregnated EVD systems are essential as a proactive defense against surgical site infections. Desu aims to strengthen the weakest link in the sterile chain by chemically preventing bacterial adhesion with its developed impregnation technologies.
In terms of the infection process, it could be seen that bacteria progress from the surface of the catheter (tunnel infection) or reach the cerebrospinal fluid through the lumen. Antibiotic impregnated EVD systems prevent bacteria from adhering to and multiplying on the catheter surface thanks to antimicrobial substances added to the polymer structure of the catheter. This technology not only provides passive protection but also offers an active defense mechanism.
Mechanism of Action in Antibiotic Impregnated EVD Systems
While standard catheters create a suitable environment for bacteria, antibiotic impregnated EVD systems provide continuous drug release. Systems manufactured by Desu typically use broad-spectrum antibiotic combinations such as Rifampicin and Clindamycin. These substances are incorporated into the silicone structure of the catheter using a special impregnation method. When the catheter comes into contact with body fluids or CSF, the antibiotics are regularly released onto the catheter surface. This local release creates a sterile micro zone around the catheter where bacteria cannot survive.
Highly effective against gram positive bacteria, these systems protect only the critical area without the need for systemic antibiotic use. The success of Desu Medical products in this field is based on the antibiotic not being suddenly released from the catheter and its effectiveness being maintained throughout the drainage period (usually up to 21 days).
Clinical Efficacy and Ventriculitis Reduction
Extensive research shows that the use of antibiotic impregnated EVD systems significantly reduces infection rates compared to standard catheters. The risk of infection increases, especially in patients requiring long term drainage, as well as in patients with subarachnoid hemorrhage or trauma. Impregnated catheters reduce this cumulative risk.
Desu Medical’s antibiotic impregnated systems are specifically designed to prevent the proliferation of drug resistant bacterial strains. Biofilm is an effective defense mechanism developed by bacteria against antibiotics. However, antibiotic impregnated EVD systems prevent biofilm formation from the outset by inhibiting the adhesion phase of bacteria to the surface. This eliminates the risk of treatment resistant ventriculitis, one of the most challenging complications surgeons may encounter post operatively.
Cost-Effectiveness of Antibiotic-Impregnated EVD Systems
From a health economics perspective, the cost of antibiotic coated catheters may appear higher than standard catheters. However, considering the expenses incurred by the hospital due to a single case of ventriculitis (intensive care duration, additional antibiotic costs, reoperations), the use of antibiotic coated EVD systems provides significant long term economic savings.
Desu Medical aims to reduce total treatment costs by lowering infection rates with these innovative products offered to healthcare institutions. Reducing the time a patient spends in intensive care is a major gain in terms of both patient comfort and the efficient use of hospital resources.
Desu Medical’s Impregnation Technology and Safety
Not all antibiotic coated catheters perform at the same level. The integrity of the impregnation process should not affect the mechanical structure (flexibility, durability) of the catheter. Desu uses special polymerization methods in the production of antibiotic impregnated EVD systems. These methods ensure that the antibiotic is present not only on the surface of the catheter but throughout its entire length. This protects both the outer part of the catheter and its inner part (the area through which CSF flows).
Furthermore, the amount of antibiotic selected must be low enough to avoid systemic toxicity but high enough to kill local bacteria. Desu products are manufactured from reliable materials that have passed biocompatibility tests and do not cause any irritation or allergic reactions when interacting with brain tissue.
Usage Protocol and Durability
The use of antibiotic coated EVD systems in clinical practice does not require a surgical process different from standard EVD sets.
The surgeon can place the catheter using their usual method. However, the protection provided by the product extends the safe period during which the catheter can remain in place. While standard catheters must be changed frequently due to the risk of infection Desu’s antibiotic coated systems can be used safely for longer periods.
This durability reduces the need for reinsertion. Avoiding repeated trauma to the patient’s scalp and brain tissue accelerates the healing process. Desu emphasizes that the effectiveness of its products is based on data validated in laboratory conditions and clinical settings.
The Difference Between Antibiotic Coated EVD Systems and Silver Coated Catheters
Silver coated catheters are also available on the market for infection control. However, the neurotoxic potential of silver ions and their insufficient antibacterial efficacy in some cases have led surgeons to seek more specific solutions. Antibiotic eluting EVD systems offer targeted protection against hospital infection agents commonly seen in neurosurgical intensive care settings. The antibiotic combinations preferred by Desu are substances that provide the highest proven efficacy against these microbes.
While antibiotic impregnated EVD systems may appear to be a simple material change, they are a strategic choice that significantly improves patient outcomes. These systems, which prevent infection from becoming a random occurrence, create a biological barrier, and ensure the treatment process, are an indispensable part of modern medicine. Desu continues to offer the most reliable solutions in this field with its high production standards and product development stages based on scientific data.
