Needleless Sampling and Medication Delivery: A Painless Innovation During CSF Irrigation

Area of Science:

• Neurosurgery
• Medical Devices
• Infectious Disease Management

Background:

• IRRAflow is a novel closed system for active cerebrospinal fluid (CSF) exchange.
• It is used to treat hemorrhagic strokes and intracranial infections, delivering medications at up to 180 mL/h.
• Accessing the closed system for CSF sampling or medication infusion can disrupt sterility.

Purpose of the Study:

• To report a novel needleless extension technique for maintaining sterility.
• To assess the compatibility and safety of this technique with the IRRAflow system.

Main Methods:

• A needleless extension, including a stopcock with a 3-way valve and needleless connectors, was used in 5 patients.
• The extension was connected to the IRRAflow catheter's irrigation and drainage ports.
• Sterile techniques were employed for CSF sampling and medication delivery.

Main Results:

• The needleless extension enabled efficient fluid exchange, CSF sampling, and medication delivery.
• The system remained sterile, preventing secondary infections despite repeated interventions.
• The needleless extension proved compatible with the IRRAflow device.

Conclusions:

• The needleless extension provides a simple, safe method for interacting with the closed IRRAflow system.
• Sterility is maintained during CSF sampling and medication delivery.
• This technique enhances the management of patients requiring CSF exchange therapy.
