Abdominal Organ Lacerations with Peritoneal Lavage Procedure to Check for Blood - Medical Illustration, Human Anatomy Drawing
This illustration shows traumatic abdominal injuries with associated diagnostic steps using peritoneal lavage to detect intra-abdominal bleeding. The anterior abdominal cutaway reveals multiple superficial lacerations on the liver's right lobe and three large lacerations on the spleen's outer surface, leading to hemoperitoneum, or blood accumulation within the abdominal cavity. The peritoneal lavage procedure, depicted in steps A to C, involves inserting a soft, flexible catheter into the abdominal cavity. If blood is aspirated (step B), the test confirms abdominal trauma. If no blood is initially drawn, saline is introduced into the cavity; if bloody fluid subsequently drains out (step C), the lavage is positive for internal bleeding.
