Educational Pearls:
Thoracotomy
Thoracotomy is used in traumatic cardiac arrest to replace conventional CPR with direct access to the chest.
Goals include identifying and controlling reversible causes of bleeding, prioritizing blood flow to the heart and brain, and performing open cardiac massage.
Trauma categories
Penetrating trauma: Gunshot wounds and stab wounds.
Has a higher chance of survival because the injury may be localized and directly repairable.
Cardiac stab wounds may have the highest survivability because the defect can be visualized, repaired, and treated with blood administration.
Blunt trauma: Motor vehicle collisions and falls from height.
Has a much lower chance of survival.
Western guidelines
EMS must witness the patient lose pulses.
Penetrating trauma: CPR for less than 15 minutes.
Blunt trauma: CPR for less than 10 minutes.
Survival decreases to essentially zero beyond these time limits.
Eastern guidelines
Focus on the presence of signs of life in blunt or penetrating trauma.
Signs of life may include:
Pupillary response.
Measurable blood pressure.
Purposeful movement.
Patient selection
Thoracotomy should only be performed when the patient has a reasonable chance of survival.
It is a highly morbid procedure with significant occupational risks, including needlestick injury.
Appropriate patient selection and timing are essential.
Procedure
Begin on the left side of the chest.
Cross-clamp the aorta to restrict blood flow below the heart and prioritize circulation to the heart and brain.
Identify and repair visible sources of bleeding involving structures such as the heart or lungs.
Perform open cardiac massage as the equivalent of CPR.
ACLS medications may still be administered.
