Pericardiocentesis During Transport for Cardiac Tamponade Complicating Acute Type A Aortic Dissection

The use of bedside ultrasound imaging has become a valuable tool in emergency medicine, and its use in the transport environment is increasing. Survival Flight, the critical care transportation program at University of Michigan/Michigan Medicine, began to train flight nurses in its use beginning in 2014. Nurses were trained during mandatory training sessions, with different skills and interpretations gradually added. Nurses who have been trained in procedures such as pericardiocentesis are empowered to use that training to perform procedures via online or, if necessary, offline medical direction. The Butterfly IQ+ devices are currently utilized. Pericardiocentesis can be a lifesaving procedure for pericardial tamponade. However, its use in relieving tamponade caused by thoracic aortic dissection remains controversial due to the possibility of worsening the dissection with restoration of more normal blood pressure. We report 2 cases of in-transport, ultrasound-guided pericardiocentesis for 2 patients with tamponade caused by type A aortic dissection and discuss its use in this clinical situation.
