Risk Factors for Serious Hypotension Induced by Intravenous Acetaminophen in Patients With Hematologic Malignancy

Area of Science:

• Pharmacology
• Critical Care Medicine
• Hematology

Background:

• Intravenous acetaminophen (AAP) is frequently used for fever in critically ill patients due to its rapid effects.
• However, the risk of hypotension following intravenous AAP, especially in vulnerable populations, requires further investigation.

Purpose of the Study:

• To identify risk factors for serious hypotension after intravenous acetaminophen administration in patients with hematologic malignancies.

Main Methods:

• Retrospective study of hospitalized hemato-oncology patients receiving intravenous AAP.
• Comparison of patients who experienced serious hypotension versus those who did not.
• Univariable and multivariable analyses to determine risk factors.

Main Results:

• 37 patients developed serious hypotension; 111 served as controls.
• Risk factors identified: elevated pre-administration body temperature, acute kidney injury, and bacteremia.
• Higher mean arterial pressure before administration was associated with reduced hypotension risk.

Conclusions:

• Patients with hematologic malignancies receiving intravenous AAP face risks of serious hypotension.
• Pre-existing conditions like fever, AKI, and bacteremia increase this risk.
• Close blood pressure monitoring during intravenous AAP administration is crucial for patient safety.
