Posicionamiento postoperatorio de la cabecera tras drenaje de hematomas subdurales crónicos por trepanación: Revisión sistemática y metaanálisis de estudios controlados aleatorizados

There were no differences regarding frequency of symptomatic recurrences, reoperations or medical complications in patients who were maintained in a flat position compared with those whose bed header was elevated during the postoperative course. Despite there being consistency between the results, there is a potential risk of bias; thus proscribing definitive recommendations until studies with higher methodological quality are available.
