Don’t Keep Cool
Hypothermia is back in the focus of discussions and was not only used for treatment after cardiac arrest. If hypothermia would protect after cerebral ischemia after an arrest it might be also useful after other impacts like stroke or meningitis.
To answer this question a french multi-center study was started involving 49 intensive care units. Patients with communitiy acquired bacterial meningitis and a GCS of less than 8 for less than 12 hours were enroled. The hypothermia group was cooled to 32-34°C for 48 hours and then passively rewarmed. Primary outcome was GCS at three months. After including 98 patients the study had to be stopped on the request of the data ans safety monitoring board due to concerns over excess mortality in the hypothermia group. Analysis showed no improve of outcome but might actually be harmful to patients.
Hypothermia doesn’t seem to be the magic bullet here either.
