Traumatic cardiac arrest
Traumatic Cardiac Arrest
Traumatic cardiac arrest (TCA) (/trəˈmatɪk kɑːrdiːæk əˈrɛst/) is a medical condition where the heart ceases to function due to physical injury.
Etymology
The term "traumatic cardiac arrest" is derived from the Greek word "trauma" meaning wound, and the Latin words "cardia" meaning heart, and "arrest" meaning to stop.
Definition
Traumatic cardiac arrest is a state of cessation of the heart's normal rhythmic contractions following a traumatic injury. This can occur as a result of direct injury to the heart, significant blood loss, or other severe bodily harm.
Causes
The most common causes of TCA include blunt force trauma, penetrating trauma, and blast injury. Other causes can include electric shock, hypoxia, and hypothermia.
Treatment
Treatment for TCA often involves immediate cardiopulmonary resuscitation (CPR), defibrillation, and emergency surgical intervention. The specific treatment will depend on the cause and severity of the injury.
Prognosis
The prognosis for TCA is generally poor, with survival rates significantly lower than for non-traumatic cardiac arrest. However, early intervention and aggressive treatment can improve outcomes.
