Cardiac arrest due to severe hyperkalaemia in patient taking nabumetone and low salt diet

摘要

We describe the case of a woman with underlying renal insufficiency who developed hyperkalaemia while taking a non-steroidal anti-inflammatory drug and, probably more importantly, a low salt preparation that was also high in potassium. This 70 year old woman had suffered from sero-positive, erosive rheumatoid arthritis for about 17 years, mainly managed with non-steroidal anti-inflammatory drugs and simple analgesics. She developed hypertension about three years before presentation but had not been taking any regular antihypertensive treatment.
