[Wound drainage with a continuous high vacuum drainage system and a drainage system with variable vacuum]

Abstract

A study of 120 total hip replacements showed the advantages of the variable vacuum drainage system over the continuous high vacuum drainage system. Better wound healing, less severe hematomas and less occlusion of drains confirmed the higher effectiveness of secretion draining. With regard to hygienic aspects, and especially to wound infection, the continuous closed drainage system is an improvement of the intermittent closed drainage system.
