Population ageing has accelerated worldwide over recent decades. In the European Union, more than one in five individuals is now aged 65 years or older. As the population ages, the incidence of disease correspondingly increases, with disorders affecting the central nervous system (CNS) and the brain representing a major cause of mortality and morbidity globally. This scenario has contributed to a rise in the number of neurosurgical procedures, after which careful monitoring of physiological and neurological parameters is essential to ensure treatment efficacy and preserve patient health. Among these parameters, a rise in temperature is one of the earliest warning signs requiring clinical attention, as it may indicate the presence of potential postoperative complications, particularly surgical-site infection.
