\n# METHODS\n\nn recent 10 years,mild hypothermia therapy hasbeen used for treatment of the patients with severebrain injury.However,the criterion of therapy hasnot been standardized.At present,there are differentopinions about mild hypothermia therapy.In 1998,Shiozakz and colleagues reported that mild hypothermiawas effective in preventing ICP elevation in patientswith ICP level higher than 20 mm Hg but less than40 mm Hg after conventional therapies.¹Up to now,there are no conclusions about whether mildhypothermia therapy has any advantage overnormothermia therapy in patients whose ICP can bemaintained at lower than 25 mm Hg by usingconventional therapy.We observed the effect of mildtherapeutic hypothermia on patients with lowerintracranial pressure following severe brain injury.  \n# Patients and grouping\n\nForty severe brain-injured patients(GCS≤8)were admitted to our hospital within 24 hours afterinjury.Emergency operation and/or conventionaltherapy(mannitol,corticosteroid and barbituratetherapy)were administered after which ICP levels ofpatients were lower than 25 mm Hg(mean  \n20.8mm Hg).The patients were randomly dividedinto two groups.the mild hypothermia group(HTgroup,20 patients)and the normothermia group(NTgroup,20 patients).There were no obviousdifferences in patients'condition such as age,sex,thelevel of ICP as well as other therapy between twogroups.  \nAll patients were initially intubated and treatedwith fluid restriction at 1 ml·kg-¹·h-¹.Afterinjury,standard computerized tomography(CT)scanof the head was obtained for every patient.Intraventricular catheter was placed in each patient forcontinuous ICP monitoring and intracranial temperaturemonitoring.  \nDepartment of Neurosurgery,Minhang Hospital of RuijinHospital
