Long peripheral catheters are 6–15 cm peripheral dwelling catheters that are inserted via a catheter-over-needle or direct Seldinger (catheter-over-guidewire) technique. When inserted in the upper extremity, the distal tip terminates before reaching the axilla, typically no further than the mid-upper arm. This is distinct from a midline catheter, which is inserted via a modified Seldinger technique and terminates at the axilla. The nomenclature of this catheter is confusing and inconsistent. We have identified over a dozen labels in the literature, all describing the same device. These include ‘15 cm catheter’, ‘catheter inserted with a Seldinger method’, ‘extended dwell/midline peripheral catheter’, ‘Leaderflex line’, ‘long catheter’, ‘long IV catheter’, ‘long peripheral cannula’, ‘long peripheral catheter’, ‘long peripheral venous catheter’, ‘long polyurethane catheter’, ‘midline cannula’, ‘mini-midline’, ‘peripheral intravenous catheter’, ‘Seldinger catheter’, ‘short midline catheter’, ‘short long line’ and ‘ultrasound-guided peripheral intravenous catheter’. The purpose of this editorial is to achieve some level of standardisation in the nomenclature of this device. Is it time to address the confusion? We suggest adopting ‘long peripheral catheter’. However, we encourage discussion and debate in reaching a consensus.
