AimTo determine an optimal head elevation degree to decrease intracranial pressure in postcraniotomy patients by meta-analysis.BackgroundA change in head position can lead to a change in intracranial pressure; however, there are conflicting data regarding the optimal degree of elevation that decreases intracranial pressure in postcraniotomy patients.DesignQuantitative systematic review with meta-analysis following Cochrane methods.Data SourcesThe data were collected during 2014; three databases (PubMed, Embase and China National Knowledge Internet) were searched for published and unpublished studies in English. The bibliographies of the articles were also reviewed. The inclusion criteria referred to different elevation degrees and effects on intracranial pressure in postcraniotomy patients.Review MethodsAccording to pre-determined inclusion criteria and exclusion criteria, two reviewers extracted the eligible studies using a standard data form.ResultsThese included a total of 237 participants who were included in the meta-analysis. (1) Compared with 0 degree: 10, 15, 30 and 45 degrees of head elevation resulted in lower intracranial pressure. (2) Intracranial pressure at 30 degrees was not significantly different in comparison to 45 degrees and was lower than that at 10 and 15 degrees.ConclusionPatients with increased intracranial pressure significantly benefitted from a head elevation of 10, 15, 30 and 45 degrees compared with 0 degrees. A head elevation of 30 or 45 degrees is optimal for decreasing intracranial pressure. Research about the relationship of position changes and the outcomes of patient primary diseases is absent.© 2015 John Wiley & Sons Ltd.
