Fever in the neurosurgical patient

Area of Science:

• Neurology
• Critical Care Medicine
• Infectious Diseases

Background:

• Fever is common in neurosurgical intensive care unit (NICU) patients.
• Temperature elevations often lead to diagnostic challenges for the critical care team.
• Limited literature exists to guide etiologic diagnosis of fever in this population.

Purpose of the Study:

• To discuss common causes of fever in neurosurgical patients.
• To highlight the importance of recognizing specific fever types in this demographic.
• To provide a diagnostic approach for fever in the NICU setting.

Main Methods:

• Review of common fever etiologies in neurosurgical patients.
• Discussion of clinical and laboratory clues for diagnosis.
• Emphasis on differentiating central fever, posterior fossa syndrome, and drug fever.

Main Results:

• Identified common causes: central fever, wound infection, nosocomial pneumonia, posterior fossa syndrome, line sepsis, urosepsis, and drug fever.
• Highlighted the critical need to recognize central fevers, posterior fossa syndrome, and drug fevers.
• Stressed the potential harm of inappropriate antimicrobial therapy.

Conclusions:

• Accurate diagnosis of fever in neurosurgical patients is crucial.
• Distinguishing central fever, posterior fossa syndrome, and drug fever prevents unnecessary antibiotic treatment.
• Clinical and laboratory findings guide effective fever management in the NICU.
