The aim of this study was to evaluate the effects of different head of bed (HOB) elevations and body positions on intracranial pressure (ICP) and cerebral perfusion pressure (CPP) and to identify safe positions for neurosurgical patients with different Glasgow Coma Scale (GCS) scores. Methods: This study with a quasi-experimental, prospective repeated measures is designed with control over the intervention consisted of 30 patients hospitalized in the neurocritical care units (NCU). Patients’ HOB was elevated (degree of 15,30,45) and the patients were at supine, left lateral and right lateral positions. ICP and CPP were recorded for each patient. Results: It was found that ICP increased and CPP decreased at supine, left and right lateral positions with different HOB elevations, which, however, did not reach statistical significance. When patients with a GCS score of 3Y8 were at degree of 15 right and left lateral positions and 45 right lateral position; and when patients with a GCS score of 13Y15 were positioned at degree of 15 left lateral, ICP and CPP changed significantly. Conclusion: The results of this study showed that different positions the patients’ HOB (degree of 15,30,45) led to slight insignificant changes in ICP and CPP; and these values were maintained within the ranges established by recent guidelines.
