[Cardiac tamponade by right atrial laceration due to blunt chest trauma in a 3-year-old child].
The case of 3-year-old girl severely injured, as restrained car passenger in a road crash, is reported. She presented with isolated circulatory failure, without specific clinical signs except skin contusions corresponding to seat belt. Because of mediastinum enlargement on systematic chest X-ray, a pericardial effusion was suspected, which was confirmed by echography, rapidly complicated by an acute tamponade without visible cause on CT-scan. The radiological assessment showed a moderate peritoneal haemorrhage related to a splenic injury. A persistent haemodynamic instability required a pericardial puncture, after rapid sequence tracheal intubation of the child, but without clinical improvement, despite fluid bolus, red-blood cell transfusion and epinephrine infusion. The child was rapidly transferred to the cardiac operating room for sternotomy, which showed a right atrial laceration. The injury was repaired, allowing the child to survive without disability. Tamponade due to traumatic cardiac injury is extremely rare in children. The clinical diagnosis is particularly difficult to establish in the context of polytrauma. The classical symptoms of cardiac tamponade are rarely complete. The association of chest injury, isolated circulatory failure and enlargement of mediastinum at chest X-ray should alert the physician. As the severity of these injuries is high, a rapid and multidisciplinary management is required, as well as specific anaesthetics precautions.
