ECMO Flow as a Sign of Intraabdominal Hemorrhage After Prolonged CPR.
Although life-saving, cardiopulmonary resuscitation (CPR) has been associated with traumatic injuries in adult patients surviving cardiac arrest. In addition to rib and sternal fractures, intraabdominal injuries have also been shown to occur, particularly after prolonged external cardiac massage. Early detection of these injuries remains difficult and is often masked by concomitant hemodynamic instability and the higher likelihood of other injuries such as retroperitoneal hemorrhage. Accurate diagnosis is further complicated when venoarterial (VA) extracorporeal membrane oxygenation (ECMO) is instituted. As such, it is imperative for ECMO providers to maintain a high index of suspicion for intraabdominal/intraperitoneal solid organ injury and hemoperitoneum when managing patients who survive prolonged cardiac arrest. Furthermore, fluctuating or low ECMO circuit flow rates despite volume infusion may serve as indicators of intraabdominal bleeding and should be promptly assessed.
