[Mathematical model of hydrodynamic flow in irrigation-suction drainage].

The aim of this study was to evaluate the flow of fluid between closed drains in deep wounds and osteomyelitic and abscess cavities. For the purposes of this study we created a numerical wound model. This model had a symmetric geometrical shape and we simulated flow of fluid between the drains in four variants of distance between these drains. The results of this model showed that the distance often used between drains in clinical practice is not effective. Better drainage could be achieved by spacing the drains more. These results can be used for more functional and better drainage if drains are placed properly in osteomyelitic or wound cavities.
