Neuraxial connectors: The new ISO 80369-6 design standard

GEDSA Guidance on the Introduction of NRFit®

To reduce the risk of wrong route delivery of fluids and gases (tubing misconnections) there is an ongoing effort led by the International Organization for Standardization (ISO) to address small bore connectors for healthcare applications.

The objective of the ISO 80369 series of standards is to specify designs of small-bore connectors for various clinical applications to reduce the likelihood of tubing misconnections. The Final Draft International Standard 80369-6 that focuses on neuraxial connectors has been approved and recognized.

Reducing the Risk of
Tubing Misconnections

In an effort to improve patient safety, medical device tubing connectors are changing to meet international design standards. The universal design of the current Luer connector has allowed for the possibility of connections between devices that are not intended to connect. All medical devices that connect to the neuraxial route will eventually use the 80369-6 connector.

In preparation to meet ISO 80369-6 standards, devices for wound infiltration, anesthesia delivery, and other regional anesthesia procedures, or to monitor or remove cerebra-spinal fluid for therapeutic or diagnostic purposes will change to the new NRFit connector.

Because the 80369-6 connector will not connect to standard Luer equipment, current equipment used with neuraxial medical devices, including customized packs, should be reviewed to ensure necestsary devices will have the new connector design. A small number of low-risk specialty devices may continue to use Luer in the short term. Neuraxial Application Sites Sites for the neuraxial application include the spine, intrathecal or subarachnoid space, ventricles of the brain and epi-, extra-, or peri-dural space. For the purpose of this standard, local anaesthesia injected hypodermically is not considered a neuraxial application.

Applications Impacted
Changes to neuraxial connectors (NRFit) will follow ISO standard 80369-6 design.
All medical devices which connect to the neuraxial route will eventually use the 80369-6 connector.

Examples of devices affected include:

  • Spinal needles
  • Neuraxial/epidural syringes and syringe caps
  • Manometers
  • Tuohy needles
  • Epidural catheters
  • Epidural filters
  • CSE kits (combined anaesthesia)
  • Drawing up filter needles
  • Drawing up kwills
  • Taps (2- or 3-way taps) to be used with manometers
