Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Sterile Potassium Chloride Concentrate
Treatment: Drugs - Sterile Potassium Chloride Concentrate

Experimental: Continuous - This group will receive potassium chloride by continuous infusion on a sliding-scale system based on serum potassium level.

Active Comparator: Intermittent - This arm will form the control group and receive potassium chloride by intermittent infusion as per conventional management


Treatment: Drugs: Sterile Potassium Chloride Concentrate
Continuous infusion, 40mmol in 40ml, starting at 10ml/hr, rate altered according to serum potassium level checked 2 hourly

Treatment: Drugs: Sterile Potassium Chloride Concentrate
By intermittent infusion, 20mmol diluted in 100ml 0.9% NaCl, administered over 60 mins, serum potassium level checked 2 hourly, and repeat doses administered as appropriate

Summary
Brief summary
Patients in critical care often require supplemental potassium chloride if levels in their
blood are below acceptable level. Common practice is to administer a single dose of potassium
chloride under controlled conditions via a drip, before checking if a further dose is
required. The purpose of this study is to ensure that it is safe to administer potassium
chloride continuously with the dose varied according to patient needs.
