Abdominal Trauma in the Major Trauma Victim (including assault and abuse in children)
Diagnosis. Possible intra-abdominal injury indicated by:
Systolic blood pressure less than 100 or hematocrit <29.
 No criterion is absolute; so use clinical judgment.
"Lap-belt ecchymosis" in children is associated with hollow organ injury, lumbar spine fracture, solid organ (liver/spleen) injury.
Elevated ALT and AST may indicate liver injury.
Physical exam only about 65% accurate.
Associated with the presence of chest injuries.
Associated with the presence of pelvic fractures.
Penetrating trauma of the abdomen requires exploration if penetrates the peritoneum.
 Some centers are doing CT only but not yet universally accepted as standard of care.
Blunt trauma of the abdomen.
If hemodynamically unstable and have acute abdomen, need laparotomy. Do not wait for CT or diagnostic peritoneal lavage (DPL) before consulting surgery.
If hemodynamically stable and patient is complaining of abdominal pain or is intoxicated or head injured, or there is an associated injury noted above, proceed with CT or DPL. Both CT and DPL have strengths and weaknesses.
