The April 2010 CHPSO Patient Safety News discussed the risks of
using standard Luer fittings for non-intravenous uses.
Inappropriate connections can occur, such as intrathecal
injection of an intravenous medication (e.g., vincristine).
Developing non-interoperable connectors, so that connectors for
fundamentally different uses cannot connect with each other, will
prevent most of these incidents.
Since that report, some progress has been made. The basic
standard (ISO 80369- 1) has just been issued, establishing six
classes of fittings that must only connect to fittings within its
class: driving gases and breathing system ancillary ports,
enteral feeding, urological access, limb cuffs, neuraxial access
and vascular access.
Work is progressing on the standards for enteral feeding and
neuraxial fittings, but some standards committee members are
expressing concern about meeting the California legal requirement
for noncompatible fittings by 2013 for enteral devices and 2014
for neuraxial devices. Early availability of these devices might
not occur. For example, the proposed neuraxial fittings are not
currently produced by anyone.
