Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Devices - Bilateral Peripheral Intravenous Catheterisation

Experimental: Left More Flexible Right Less Flexible - Participants in this arm will have a more flexible catheter placed in their left arm.

Experimental: Left Less Flexible Right More Flexible - Participants in this arm will have a less flexible catheter placed in their left arm.


Treatment: Devices: Bilateral Peripheral Intravenous Catheterisation
Participants will have peripheral intravenous catheters inserted. Each participant will receive two different catheters (less flexible = 20 gauge ICUMedical SuperCath5 SP120-20-31T; more flexible = 20 gauge Becton Dickinson Insyte Autoguard Blood Control 381034), with the treatment arm (more flexible) being randomly assigned.
