Abstract:
Objective To explore the drainage effect of drainage tube with different materials on the basis of a constant nega tive pressure drainage,and its impact on flap survival.Methods The most common clinical used Polyvinyl chloride resin (PVC)pipe,latex tubes,silicone tube drainage tubes,and flaps were compared at different phases of the drainage,to determine the best clinical flap with drainage material.After three groups of flaps were designed,including a constant negative pressure drainage device,without a constant negative pressure drainage system,and drainage alone (no negative pressure) drainage flap,the flap survival was observed at different phase space.Three different drainage drainage ways of the flap and the flap survival area of effect were statistically analyzed.Results The silicone tube drainage was more fully and effectively.Constant negative pressure drainage volume of liquid was up to the flap with drainage to the fullest,the highest rate of skin flap healing,and better healing.Conclusions The constant negative pressure in the drainage of the flap makes drainage more fully,and promotes rapid healing of wounds,while the silicone tube is suitable for flap drainage.
