Effects of a Portable Peritoneal Lavage Device on Dogs with Seawater-Immersed Open Abdominal Injury

Figure 3

H-E staining of the stomach, small intestine, heart, and lung tissue in dogs with different treatments at each time point (100x). Dogs were euthanized at 2 h after open abdominal injury, 3 h after the dogs were pulled up from seawater, 2 h after delayed lavage (group A), 2 h after timely lavage (group B), and 2 h after timely lavage with the device (group C). The lung, stomach, small intestine, and heart tissues were harvested immediately after the dogs were euthanized. After fixation, paraffin embedding, sectioning, and HE staining, the pathological changes of the tissues were observed under a microscope.
