Vital signs are notable for: HR: 155 beats/min BP: 82/44 mmHg RR: 30 breaths/min Physical examination reveals faint bruising over the abdomen and scattered ecchymoses on the back. Abdominal palpation elicits diffuse tenderness and guarding. Laboratory studies show: Hemoglobin: 8.2 g/dL AST: 310 U/L ALT: 275 U/L Lipase: 650 U/L A CT scan of the abdomen demonstrates a pancreatic transection and small amount of free intraperitoneal fluid.
