Prehospital Resuscitative Thoracotomy for Traumatic Cardiac Arrest.

Area of Science:

• Emergency medicine
• Trauma surgery
• Cardiovascular surgery

Background:

• Traumatic cardiac arrest (TCA) poses a significant challenge in trauma care due to its rapid onset.
• Limited time windows exist for effective intervention following traumatic injury.

Purpose of the Study:

• To assess the association between prehospital resuscitative thoracotomy and survival outcomes in patients experiencing traumatic cardiac arrest.
• To evaluate the feasibility and effectiveness of this intervention in a real-world prehospital setting.

Main Methods:

• Retrospective cohort study of 601 patients undergoing prehospital resuscitative thoracotomy for TCA in London (1999-2019).
• Data analysis focused on survival to hospital discharge, survival to admission, and neurological status.
• Multivariable analysis identified factors associated with survival.

Main Results:

• Overall survival to discharge was 5.0% (30/601), with 76.6% of survivors having favorable neurological outcomes.
• Survival rates varied significantly by cause: 21% for cardiac tamponade, 1.9% for exsanguination.
• Survival was limited to within 15 minutes for cardiac tamponade and 5 minutes for exsanguination.

Conclusions:

• Prehospital resuscitative thoracotomy is a viable intervention in advanced urban prehospital systems for TCA.
• The procedure is particularly beneficial for patients with cardiac tamponade and limited treatment options.
• Timeliness and cause of arrest are critical determinants of survival following resuscitative thoracotomy.
