Prehospital Trauma Life Support (PHTLS) Pre Test And Post Test Practice

Intra-abdominal bleeding in trauma most seriously shows up as signs of peritoneal irritation and ongoing blood loss. Abdominal tenderness or distension suggests the abdomen is reacting to bleeding or injury inside. Guarding and rigidity indicate the muscles tensing to protect a injured area, often with blood in the peritoneal cavity. Referred pain can occur when irritation from blood or organ injury affects the diaphragm or other structures. If a patient becomes hypotensive without another clear source of blood loss, that indicates significant intraperitoneal hemorrhage, especially when the abdomen isn’t the only plausible explanation for instability. So, the combination of abdominal signs (tenderness, distension, guarding, rigidity) plus referred pain and unexplained hypotension specifically points toward intra-abdominal bleeding. In contrast, a normal abdomen with stable vitals, an isolated limb fracture with a normal abdominal exam, or chest symptoms with a clear abdomen do not raise the same concern for intra-abdominal hemorrhage at that moment.
