Winged Metal Needles versus Plastic Winged and Nonwinged Cannulae for Subcutaneous Infusions in Palliative Care: A Quality Improvement Project To Enhance Patient Care and Medical Staff Safety in a Singaporean Hospital

The winged vialon cannula was the most durable, with no site reactions or mechanical complications, tolerating a volume comparable to that of the metal needle. We suggest its utilization for continuous subcutaneous infusions and consideration of future randomized controlled trials with an integrated economic evaluation for further in-depth comparisons of subcutaneous indwelling devices.
