Abstract
Purpose
Postoperative fever is a common problem following neurosurgery but data on the causes among paediatric patients is sparse. In this report, we determined the incidence, causes, and outcomes of postoperative fever in paediatric neurosurgical patients (< 18 years), and contrasted the findings with an adult cohort published recently from our unit.
Methods
We recruited 61 patients who underwent 73 surgeries for non-traumatic neurosurgical indications over 12 months. A standard protocol was followed for the evaluation and management of postoperative fever. We prospectively collected data pertaining to operative details, daily maximal temperature, clinical features, and use of surgical drains, urinary catheters, and other adjuncts. Elevated body temperature of > 99.9 °F or 37.7 °C for > 48 h or associated with clinical deterioration or localising features was considered as “fever”; elevated temperature not meeting these criteria was classified as transient elevation in temperature (TET).
Results
Twenty-six patients (35.6%) had postoperative fever, more frequent than in adult patients. TET occurred in 12 patients (16.4%). The most common causes of fever were aseptic meningitis (34.6%), followed by urinary tract infections (15.4%), pyogenic meningitis, COVID-19, and wound infections. Postoperative fever was associated with significantly longer duration of hospital admission and was the commonest cause of readmission.
Conclusion
In contrast to adults, early temperature elevations in paediatric patients may portend infectious and serious non-infectious causes of fever, including delayed presentation with aseptic meningitis, a novel association among paediatric patients. Investigation guided by clinical assessment and conservative antibiotic policy in keeping with the institutional microbiological profile provides the most appropriate strategy in managing paediatric postoperative fever.
