The blood supply to a Meckel's diverticulum exists either within the small bowel mesentery, or within a separate mesodiverticular band. The latter is associated with bowel obstruction. It is a rare source of hemorrhage. The case report describes hemoperitoneum resulting from blunt trauma-induced disruption of a mesodiverticular band.

Although adequate volume resuscitation has decreased mortality from hemorrhagic shock, recovery in many patients is complicated by sepsis. To determine whether a subject debilitated by hemorrhagic shock would exhibit greater cardiocirculatory dysfunction when challenged with sepsis, ten dogs (Group I) were hemorrhaged to a mean arterial blood pressure of 30 mm Hg. After 2 hours of hypotension, shed blood and lactated Ringer's solution (50 ml/kg) were given, and the dogs were observed for 3 to 6 days. ⋯ Blood glucose and insulin levels were significantly elevated in the resuscitated shocked dogs, likely due to increased circulating catecholamine concentrations and enhanced glycogenolysis. Endotoxin shock caused significant hypotension, acidosis, and impaired regional perfusion in all dogs. In addition, cardiac output, stroke volume, dP/dT, and left ventricular end-diastolic pressure fell and hyperglycemia and hyperinsulinemia occurred in all dogs after endotoxin injection.(ABSTRACT TRUNCATED AT 250 WORDS)

Three consecutive successful repairs of innominate artery tears caused by blunt trauma are reported. Attention is called to the fact that the innominate artery is the second most common site of great vessel injury in this setting. ⋯ Median sternotomy, with a cervical extension if necessary, is the incision of choice. Successful repair is the usual outcome.

A young man hit by a car while riding his motorcycle presented with reversible hypotension, a compression fracture of C6, fractures of the left femur and of ribs 9-12 on the right, and right hemothorax. A falsely negative peritoneal lavage delayed laparotomy, which, when done, demonstrated two right diaphragmatic rents with bleeding into the right chest from a severe liver injury. Presentation of this case demonstrates that while peritoneal lavage is an excellent way to exclude intraperitoneal hemorrhage following blunt abdominal trauma, false-negative results may occur in the setting of hemorrhage with diaphragmatic rupture.
