Ionized Calcium as a Severity Marker in Septic Shock Patients
Evaluation of the Prognostic Value of Changes in Ionized Calcium as a Severity Marker in Septic Shock Patients in the Intensive Care Unit
Sepsis is a serious condition where the body has an extreme, dysregulated response to an infection, often leading to life-threatening organ dysfunction. Low levels of ionized calcium (the active, free form of calcium in the blood) are common in critically ill patients admitted to intensive care units (ICUs). While established clinical scoring systems like the Sequential Organ Failure Assessment (SOFA) and Acute Physiology and Chronic Health Evaluation II (APACHE II) help assess illness severity, there is a continuous need for rapid, cost-effective biological markers that can be measured immediately at the bedside using routine blood gas analyzers.
The primary purpose of this observational study is to evaluate whether ionized calcium levels measured upon admission to the ICU can serve as an early marker of disease severity and outcome in adult patients diagnosed with sepsis or septic shock.
Adult participants diagnosed with sepsis or septic shock who are admitted to the ICU will receive standard medical care. Routine arterial or venous blood samples will be analyzed at admission to measure ionized calcium and other standard laboratory markers. Researchers will correlate these calcium levels with baseline illness severity scores (SOFA and APACHE II) and evaluate patient outcomes, including 28-day mortality, length of ICU stay, and the need for mechanical ventilation or vasopressor medications.

Sepsis and Septic Shock Cohort
Adult patients (aged 18 years or older) diagnosed with sepsis or septic shock according to the Sepsis-3 definitions and admitted to the intensive care unit (ICU) within 24 hours of presentation.
Patients receive standard, evidence-based supportive care.
Ionized calcium levels along with arterial blood gases, organ failure scores (SOFA and APACHE II), and baseline laboratory parameters are assessed upon admission and monitored at 24 and 48 hours to evaluate prognostic outcomes.

Correlation Between Admission Ionized Calcium Levels and SOFA Score
Tidsramme: Baseline
|
Correlation between baseline ionized calcium levels and disease severity assessed by the Sequential Organ Failure Assessment (SOFA) score.
Scores range from 0 to 24, where higher scores indicate greater organ failure.
