Intracerebral temperature in patients with hydrocephalus of varying aetiology.

Abstract

Brain temperature was measured at various depths beneath the pial surface in patients with hydrocephalus of varying aetiology. Temperature increased gradually with depth in all patients, with the highest temperature found in the ventricle. The difference between intraventricular and rectal temperatures (delta v-r) was greater in patients who underwent continuous ventricular drainage than in patients who underwent ventriculoperitoneal shunt (continuous ventricular drainage; 1.2 (SD 0.40) degrees C, mean (SD), n=5 v ventriculoperitoneal shunt; 0.4 (SD 0.45) degrees C, n=16; p< 0.05). The difference between intracerebral and rectal temperatures (delta b2-r) was also greater in patients with continuous ventricular drainage than in patients with ventriculoperitoneal shunt (continuous ventricular drainage; 0.1 (SD 0.86) degrees C, n=5 v ventriculoperitoneal shunt; -0.7 (0.86) degrees C, n=16; p< 0.05). Among patients with normal pressure hydrocephalus, these differences were greater in the patients with better outcomes after shunt surgery than in the less improved group (delta v-r; 0.7 (SD 0.27) degrees C, n=7 v 0.1 (SD 0.40) degrees C, n=5, p< 0.01, delta b2-r; -0.2 (SD 0.61) degrees C, n=7 v -1.4 (0.90) degrees C, n=5, p< 0.01).
