[Cardiac post-resuscitation care.  An indication for trauma whole-body CT?]. 
We report the case of a 51-year-old male patient who sustained a liver rupture following mechanical cardiopulmonary resuscitation (CPR) with the LUCAS® system.  The patient was under anticoagulation and developed an abdominal compartment syndrome.  Although the use of mechanical CPR devices, such as the LUCAS® system and the load distributing band (Autopulse®), is becoming more common, there are specific complications described in the literature, which are associated with mechanical CPR.  It is important to differentiate between general complications associated with CPR and those which can be attributed to the application of mechanical CPR devices.  Using the example of the presented case, this article outlines and discusses these points based on the currently available literature.  It should also be noted that mechanical CPR can act in a similar way to chest trauma and can necessitate an investigation with contrast enhanced computed tomography.
