Background: Electrolyte abnormalities can precipitate life-threatening events. In such situations, rapid and accurate assessment of electrolyte abnormalities may enable the institution of focused therapies. The present study was conducted to determine efficacy of electrolytes assessed by point-of-care testing.
Materials & Methods: 60 patients of both genders were selected and from each patient, paired sample of arterial blood and venous blood were collected at the same time. Whole blood electrolytes were analyzed using a point-of-care blood gas analyzer and serum electrolytes were analyzed in the central laboratory.
Results: Out of 60 patients, males were 35 and females were 25. ElectrolytesABG value (mmol/L) and serum value (mmol/L) of Sodium < 130 was 127.6 and 129.3, sodium 130–145 was 134.2 and 138.5 and sodium > 145 was 150.7 and 149.3, potassium < 3 was 1.8 and 2.5, potassium 3-4 was 3.5 and 3.8, potassium >4 was 4.6 and 4.8 and potassium >5 was 6.7 and 6.0 respectively. The difference was significant (P< 0.05).
Conclusion: Practitioners should be aware of the difference between whole blood and serum electrolytes, particularly when urgent samples are tested at point of care and routine follow-up electrolytes are sent to the central laboratory

Aim: To assess serum potassium levels in Acute myocardial infarction patients.
Materials & methods: 50 confirmed cases of AMI were included in the present study. Another set of 50 age and gender-matched healthy subjects were taken as control.  Collection of venous blood samples was done in the study group on the day of admission within 12 hours from anticubital vein with all aseptic precautions in plain and vacutainers for the purpose of routine baseline blood investigations. For serum potassium levels, blood was allowed to clot at room temperature for half an hour and then centrifuged at 3000 rpm for five minutes. The serum separated was used for the estimation of serum potassium levels. Results: Mean serum potassium levels among the patients of the study group and control group were 3.89mEq/L and 4.56 mEq/L respectively. While comparing statistically, significant results were obtained. Out 50 patients of the AMI group, hypokalaemia was seen in 24 percent of the patients.
Conclusion: It is recommended that potassium levels which affect the clinical outcomes in patients of acute myocardial infarction should be monitored, and potassium replaced whenever required.
