The Reaction Level Scale (RLS85) is a "coma scale" for the direct assessment of overall reaction level in patients with acute brain disorders. It is devised for reliable use even in the management of patients who are difficult to assess, such as intubated patients and patients with swollen eyelids. We here present the manual of the RLS85 and the guidelines(More)
The Glasgow Coma Scale (GCS) and the Reaction Level Scale (RLS85) were compared for rating neurosurgical patients in regard to ranking order of deficit severity, interobserver variability, and coverage for relevant factors. Four physicians, four registered nurses, and four assistant nurses performed 72 pairwise ratings on 47 neurosurgical patients. The rank(More)
This study compares the safety and effectiveness of two methods for the prophylaxis of post-operative thromboembolism in neurosurgical patients: A: low-dose heparin (5,000 IU X 2 s.c.) started preoperatively and continued daily for one week post-operatively, and B: per-operative electrical calf muscle stimulation with groups of impulses plus post-operative(More)
A new scale for assessment of overall responsiveness, the Reaction Level Scale (RLS 85), which has been shown to have better reliability than the Glasgow Coma Scale (GCS), has been tested in four neurosurgical departments regarding inter-observer agreement and coverage i.e. the proportion of patients that could be assessed by the scale. In a carefully(More)

The human auditory sensitivity in detecting linear frequency ramps of a continuous pure tone has been studied. It is shown that for short ramp durations (less than 200 msec) discrimination depends on the difference between base and plateau frequencies, the mean threshold being about 3 Hz at 1 kHz. For longer ramp durations (greater than 200 msec),(More)
In an earlier study on post-operative thromboembolism in neurosurgery the incidence of deep vein thromboses (DVT) diagnosed by the fibrinogen uptake test and phlebography was reduced to the same extent by two different prophylactic methods (low dose heparin or calf muscle stimulation + dextran). However, patients with lower limb paresis due to a brain(More)

Previous studies have shown that 2 Hz electrical conditioning stimulation of hands and cheeks increased the tooth pain threshold. In the present study the relation between strength of conditioning stimulation and amplitude of pain threshold increase is elucidated. Intense conditioning stimulation, giving subjective beating sensations and extensive muscles(More)
