Trypanophobes Rejoice! Big IVs Hurt No More Than Little Ones
Spoon Feed —
This single centre RCT investigated the link between IV cannula diameter and how painful it will be to insert. 18G cannulas were not more painful nor more difficult to place than 20G cannulas across the spectrum of experience levels. Pain and insertion success rates being equal, patients are better off with cannulas that can accommodate higher flow rates.
