Nonobstetric emergencies in pregnancy: trauma and surgical conditions.

Nonobstetric surgical emergencies may be difficult to recognize in pregnant patients whose normal physiologic state is altered by pregnancy. Early suspicion and serial examination in pregnancy may result in appropriate interventions for appendicitis, cholecystitis, pancreatitis, and bowel obstruction. Treatment in pregnant patients who experience trauma must be systematic so that situations at risk for maternal and fetal loss can be recognized.
