[Muscular changes caused by suction drainage. Scanning electron microscopy, transmission electron microscopy, light microscopy and morphometric studies of dorsal muscles of the rat (Rattus rattus) using drainage].
Changes in the dorsal muscles of 22 rats (Wistar), resulting from surgical drain, have been studied under different morphological aspects. The lumen of drains were obstructed after a short time. In the drains without using low pressure, erythrocytes and fibrin network were seen by scanning microscopical investigation. Patent muscle fibres could be analyzed in the lumen of drain using negative pressure. They prevent the functional drain system. By the effect of surgical drains the fibres of dorsal muscles had become swollen. This fact could be analyzed by morphometrical technique. Some changes in fibres have been demonstrated by histological methods.
