Objective: This retrospective observational study conducted in a general ICU aimed to evaluate the hemodynamic impact of IV paracetamol by monitoring blood pressure, urine output, and core temperature post-administration. Design: The study was designed as a retrospective observational study in a general ICU setting. Setting: The study was conducted in a general intensive care unit (ICU). Patients: Data from 498 patients receiving IV paracetamol in various clinical contexts were analyzed. Interventions: Patients received IV paracetamol for analgesia and fever reduction as part of their clinical care. Measurements and main results: The study analyzed the hemodynamic effects of IV paracetamol by monitoring blood pressure, urine output, and core temperature post-administration. A significant decrease in mean systolic and diastolic blood pressure values was observed across different patient subgroups, notably 45–60 min post-infusion. An increase in noradrenaline dosage and a decrease in urine output indicated a decline in end-organ perfusion following IV paracetamol administration. Multivariate analysis identified associations between clinical factors (such as general anesthesia and cardiac conditions) and changes in blood pressure. Conclusions: While IV paracetamol remains a valuable therapeutic option for pain and fever management, especially in hypertensive patients with specific conditions like traumatic brain injury and cerebral vascular accident, careful monitoring, and individualized dosing strategies are recommended in critically ill patients to maintain hemodynamic stability and optimize clinical outcomes. These findings contribute to enhancing our understanding of IV paracetamol hemodynamic effects and inform evidence-based practices for its use in ICU settings.
