Insights
Hypokalemia is common in pediatric intensive care units (PICU). Rapid potassium correction improved survival rates, highlighting the importance of early detection and prompt treatment for critically ill children.
Area of Science:
- Pediatric Critical Care Medicine
- Electrolyte Imbalance
- Clinical Outcomes Research
Background:
- Hypokalemia (low potassium levels) is a frequent complication in pediatric intensive care units (PICUs).
- Identifying risk factors and understanding treatment efficacy are crucial for managing this condition.
Purpose of the Study:
- To determine the incidence, severity, risk factors, and mortality associated with hypokalemia in a PICU.
- To evaluate the effectiveness of different therapeutic approaches for correcting hypokalemia.
Main Methods:
- A retrospective analysis of 290 consecutive patient records from a PICU over one year.
- Data collected included patient demographics, primary diagnoses, nutritional status, medications, and hypokalemia episodes.
Main Results:
- Hypokalemia occurred in 14.8% of patients (54 episodes in 43 patients).
- Predisposing factors included renal disease, septicemia, diarrhea, malnutrition, and specific drug therapies.
- Rapid potassium correction via infusion resulted in survival for all treated patients, while slow correction had a lower success rate.
Conclusions:
- Hypokalemia is a significant and common issue in the PICU population.
- Early detection via regular monitoring and prompt, rapid correction of hypokalemia can improve patient outcomes and survival rates.
Objective:
To examine the frequency, severity, risk factors and mortality of hypokalemia, and efficacy of therapy used for its correction.
Design:
Descriptive, retrospective analysis.
Sample:
290 patient records admitted consecutively to a Pediatric Intensive Care Unit (PICU) over a period of one year.
Results:
Forty three (14.8%) patients had 54 episodes of hypokalemia. Predisposing factors included the nature of primary disease (renal disease 19%, septicemia 19%, acute diarrhea 14%, heart disease with congestive failure, and meningoencephalitis 12% each), malnutrition (weight for age less than 80% in 72%) and therapy with drugs (diuretics, corticosteroids and antiasthma drugs). For correction of hpokalemia all the patients received 4-6 mEq potassium per 100 ml of intravenous fluids (slow correction). Seven patients (9 episodes), with ECG changes of hpokalemia, also received infusion of 0.3 mEq potassium/kg/hour till ECG became normal (rapid correction). Normal potassium level was achieved in all nine episodes where rapid correction was given, and in 40 of 45 episodes which received slow correction. The overall mortality among patients with hypokalemia (25.6%, 11/43) was significantly higher than that among the remaining PICU patients (10.9%, 27/247; odd's ratio 2.34; 95% confidence interval 1.3-4.2) (p < 0.05). All the patients receiving rapid correction survived.
Conclusions:
Hypokalemia is a common problem among PICU patients. Early detection through regular monitoring and rapid correction may help in improving the outcome.
