Arrival GCS data were available in 17 patients with hemicraniectomy and 20 patients without hemicraniectomy.
**
ICP measurements were obtained in 19 patients with hemicraniectomy and 27 patients without hemicraniectomy. Brain temperature, core body temperature, and ΔTCore-Br, are expressed as mean ± SD of all measurements.
