Pre-hospital thoracotomy and aortic clamping in blunt trauma

This is one of those ‘wow they really do that!?‘ papers…Patients undergoing thoracotomy and aortic clamping for pre-hospital blunt traumatic arrest either in the field or in the ED were evaluated for the outcome of survival to ICU admission. None of the 81 patients who underwent this intervention survived to discharge.
Field thoracotomy resulted in shorter times from arrival of the emergency medical team to performance of the thoracotomy (19.2 vs 30.7 mins). Patients who arrested in front of the team had a greater ICU admission rate than those who were already in cardiac arrest when the team arrived (70% vs 8%).
One may argue against an intervention that seems to have resulted in no benefit to the patient. However a counterargument might be that an ICU admission allows for better end-of-life management for grieving families, and for the possibility of organ donation.
Interestingly, there were some neurologically intact survivors of emergency thoracotomy for blunt trauma by this service, although they were excluded from the study for either (i) receiving the field thoracotomy before full arrest or (ii) arresting after arrival in the ED.
