The risk factors of various kinds of fever in critically ill patients with acute stroke / 中国脑血管病杂志

ABSTRACT

Objective: To identify the risk factors of fever in critically ill patients with acute stroke in a neurological intensive care unit (NICU). Methods: The frequency of risk factors of fever in 137 stroked patients during the first 7. days after admission were retrospectively studied. Fever was defined as a patient's axillary temperature ≥37.5°C in two separate determinations or >37.8°C in one determination. We categorized the fever into 4 kinds Circled digit oneany fever, Circled digit twoexplained infectious fever, Circled digit threeexplained noninfectious fever and Circled digit fourunexplained fever based on Commichau's methods. Then logistic regression analysis was used to ascertain the risk factors of the 4 kinds of fever. Results: Any fever, explained infectious fever, unexplained fever and explained noninfectious fever occurred in 65%, 48.9%, 15.3% and 0.7% respectively. Multivariable logistic regression analysis demonstrated that patients older than 65 years, impaired consciousness, large area cerebral infarction/cerebral hemorrhage volume ≥30 ml, and deep vein catheterization used were involved into regression equation for any fever. In addition to these variables, length of NICU stay was also involved into regression equation for explained infectious fever. Brain midline shift, initial peripheral leucocytes count more than 12.0 × 10 9/L were involved into regression equation for unexplained fever. Conclusion: The risk factors differ in various kinds of fever in critically ill patients with acute stroke. Effective measures should be taken for different types of febrility.
