| Summary: | Background:
The concentrated potassium chloride injection is a high-alert medication and replacing it with a pre-mixed formulation can reduce the risks associated with its use. The aim of this study was to determine the clinical characteristics of patients receiving different potassium chloride formulations available at a private institution. The study also assessed the effectiveness and safety of pre-mixed formulations in the correction of hypokalaemia.
Methods:
This was a retrospective observational study consisting of 296 cases using concentrated and pre-mixed potassium chloride injections in 2011 in a private hospital in Kuching, Sarawak, Malaysia.
Results:
There were 135 (45.6%) cases that received concentrated potassium chloride, and 161 (54.4%) cases that received pre-mixed formulations. The patients’ clinical characteristics that were significantly related to the utilization of the different formulations were diagnosis (P < 0.001), potassium serum blood concentration (P < 0.05), and fluid overload risk (P < 0.05). The difference observed for the cases that achieved or maintained normokalaemia was statistically insignificant (P = 0.172). Infusion-related adverse effects were seen more in pre-mixes compared to concentrated formulations (6.8% versus 2.2%, P < 0.05).
Conclusion:
This study provides insight into the utilization of potassium chloride injections at this specific institution. The results support current recommendations to use pre-mixed formulations whenever possible.
