Abstract

Hypothermia has a considerable protective effect during brain ischemia. On the other hand small increases of brain temperature have a remarkable effect on the exacerbation of neurological damage following an ischemic event. Hyperthermia of the brain tissue after severe head injury is described. The effect of acutely increased intracranial pressure on cerebrovenous blood temperature is not described yet. The aim of this study was to investigate the relationship between temperature in the cerebrovenous compartment (T(cv)) and changes of the CPP in an animal model of raised intracranial pressure. Methods: A thermocouple was inserted in the sagittal sinus in 9 pigs under general anesthesia. By stepwise inflating a supracerebral and infratentorial placed balloon catheter intracranial pressure (ICP) was increased and CPP concomitantly decreased. The central body temperature was measured simultaneously in the abdominal aorta (T(a)) with a second thermocouple. Results: In our model th T(cv) was lower than T(a) at the beginning of the ICP increase. The mean difference between T(a) and T(cv), (ΔT(a-cv)) was 0.86% C (±0.44) prior to ICP increase and 1.19°C (0.58) at the maximum ICP increase. Thus, ΔT(av) increased during CPP reduction. This relation was represented by an adjusted R(square) of r2=0.89 [p
