Recent prospective controlled trials of induced moderate hypothermia (32-34 degrees C) for relatively short periods (24-48 h) in patients with severe head injury have suggested improvement in intracranial pressure control and outcome. It is possible that increased benefit might be achieved if hypothermia was maintained for more periods longer than 48 h, but there is little in the literature on the effects of prolonged moderate hypothermia in adults with severe head injury. We used moderate induced hypothermia (30-33 degrees C) in 43 patients with severe head injury for prolonged periods (mean 8 days, range 2-19 days). ⋯ Moderate hypothermia may be induced for more prolonged periods, and is a relatively safe and feasible therapeutic option in the treatment of selected patients with severe traumatic brain injury. Thus, further prospective controlled trials using induced hypothermia for longer periods than 48 h are warranted.

The Neurosurgical Society of Australasia through its Trauma Committee has a long involvement in the problem of neurotrauma. The management of acute neurotrauma in rural and remote locations is of particular interest and is part of a general policy which includes education, prevention, organization of an integrated neurotrauma system and support for the Early Management of Severe Trauma (EMST) programme instituted by the Royal Australasian College of Surgeons. The management of acute neurotrauma requires a consultative approach especially in the multiple injured patient and where transfer or retrieval is necessary. ⋯ This revision updates the guidelines and makes them accessible through the Journal. Reprints are available for practitioners in rural and remote settings, trauma course participants and others. Copyright 1999 Harcourt Publishers Ltd.

Spinal subdural haematoma is a rare entity. Only a few cases have been reported, mainly in patients with coagulopathies or bleeding diathesis, and also in patients undergoing anticoagulant therapy following surgery, trauma, or lumbar puncture. Symptoms of spinal cord compression produced by spinal subdural haematoma may progress rapidly causing complete and irreversible deficits. ⋯ She was discharged to an inpatient rehabilitation facility. Follow-up at 1 year showed significant improvement in motor function, but absence of posterior column function. A follow-up magnetic resonance study demonstrated widening of the spinal cord, advanced myelomalacia and a large, central, multi-loculated syrinx.

The effects of mild hypothermia on patients with severe traumatic brain injury.
To investigate the protective effects of mild hypothermia (33-35 degrees C) on the outcome of patients with severe traumatic brain injury (TBI) (GCS<8). ⋯ Our clinical data have demonstrated that mild hypothermia is a useful method for management of patients with severe traumatic brain injury.

Stimulation of the somatosensory system is more likely to evoke pain in patients with chronic pain after nervous system injury than in patients without somatosensory abnormalities. We now describe results of stimulation through a microelectrode at microampere thresholds (threshold microstimulation; TMIS) in the region of the human thalamic principal sensory nucleus (ventral caudal; Vc) during operations for treatment of movement disorders or of chronic pain. Patients were trained preoperatively to use a standard questionnaire to describe the location (projected field) and quality of sensations evoked by TMIS intraoperatively. ⋯ In both the core and the posterior-inferior regions, the proportion of sites where TMIS evoked pain was larger in pain-affected and unaffected areas than in control areas. The number of sites where thermal (warm or cold) sensations were evoked was correspondingly smaller, so that the total of pain-plus-thermal (sensation of warmth or cold) sites was the same in all areas. Therefore, sites pain where stimulation evoked pain in patients with neuropathic pain (i.e., pain following an injury to the nervous system) may correspond to sites where thermal sensations were evoked by stimulation in patients without somatosensory abnormality.
