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
