Signs and Symptoms
People injured in motor vehicle collisions may present with a "seat belt sign," bruising on the abdomen along the site of the lap portion of the safety belt; this sign is associated with a high rate of injury to the abdominal organs. Seatbelts may also cause abrasions and hematomas; up to 30 percent of people with such signs have associated internal injuries. Early indications of abdominal trauma include nausea, vomiting, and fever. Blood in the urine is another sign. The injury may present with abdominal pain, tenderness, distension, or rigidity to the touch, and bowel sounds may be diminished or absent. Abdominal guarding is a tensing of the abdominal wall muscles to guard inflamed organs within the abdomen. Pneumoperitoneum, air or gas in the abdominal cavity, may be an indication of rupture of a hollow organ. In penetrating injuries, an evisceration (protrusion of internal organs out of a wound) may be present.
Injuries associated with intra-abdominal trauma include rib fractures, vertebral fractures, pelvic fractures, and injuries to the abdominal wall.

“If family communication is good, parents can pick up the signs of stress in children and talk about it before it results in some crisis. If family communication is bad, not only will parents be insensitive to potential crises, but the poor communication will contribute to problems in the family.”

“In retirement, only money and symptoms are consequential.”
