Potassium solutions: risks to patients from errors occurring during intravenous administration
Reference number
1051
Issue date
31 October 2002
Type
Alert
This Patient Safety Alert aims to reduce the risk of
accidental overdose
of
intravenous
potassium arising from use of
potassium chloride concentrate solutions
and other strong potassium solutions. It also aims to ensure that seriously ill patients who urgently require intravenous potassium as part of their treatment continue to receive it promptly.
Potassium chloride concentrate solution can be fatal if given inappropriately. It is widely used and administered intravenously in diluted solutions to treat low potassium levels (hypokalaemia) in more seriously ill patients. Patients with low potassium levels may require intravenous potassium very quickly. A delay in administering this therapy could compromise patient care and risk cardiac arrest.
Reports from the UK and elsewhere have identified incidents where potassium chloride concentrate has been accidentally administered to patients with fatal results. Commonly, staff mistook potassium chloride concentrate solution for sodium chloride (normal saline) solution when reconstituting a drug for injection and thereby administered an accidental overdose of potassium.
NHS organisations should take initial action in the following areas:
storage and handling of potassium chloride concentrate and other strong potassium solutions;
preparation of dilute solutions containing potassium;
prescription of solutions containing potassium;
checking the use of strong potassium solutions in clinical areas;
and training staff appropriately.
Although the deadline for actions has passed, this guidance remains best practice. It should be followed to help prevent future patient safety incidents.
