Penetrating Chest Trauma
Traumatic arrest with witnessed signs of life* in the field
Persistent hypotension (systolic blood pressure (SBP) <60 mm Hg) despite resuscitative efforts
Blunt Trauma
Traumatic arrest that occurs in the emergency department (ED)
Persistent hypotension (SBP <60 mm Hg) despite resuscitative efforts
Pulmonary Trauma
Chest tube drainage >1,500 mL
Persistent hypotension or cardiac arrest with known lung laceration
Air Embolism
Persistent signs of hypovolemic shock
Hemoptysis and cardiac arrest after intubation and ventilation
Nontraumatic Hypothermic Cardiac Arrest
In settings where cardiopulmonary bypass is not immediately available
Goals
Relief of cardiac tamponade
Support of cardiac function with open massage, cross-clamping the aorta, and/or internal cardiac defibrillation
Control of hemorrhage
Diagnosis and management of air embolism
Mediastinal irrigation and rewarming (for hypothermic cardiac arrest)
CONTRAINDICATIONS
No signs of life and prehospital cardiopulmonary resuscitation (CPR) performed:
>15 minutes after penetrating trauma
>10 minutes after blunt trauma
Multisystem blunt trauma
Severe head injury
Asystole as an initial rhythm without tamponade
Inability to provide definitive care after procedure
RISKS/CONSENT ISSUES
This is an emergent procedure and does not require written consent
LANDMARKS (FIGURE 15.1)
Left-sided supine anterolateral approach over the 5th rib, in the fourth intercostal space
In males incise below the nipple
In females below the inframammary fold
General Basic Steps
Incision
Dissection and rib spreading
Pericardotomy
Cardiac massage
Hemorrhage control
Aortic cross-clamping
TECHNIQUE
Patient Preparation
Patient should be intubated and a nasogastric tube should be placed (this should not delay the procedure!)
Place towels under the left chest and place left arm above the head
Sterilize the incision area with copious povidone–iodine solution
Incision
Using a no. 20 blade, incise from the sternal border to the posterior axillary line
During the primary incision, cut firmly through subcutaneous tissue to the intercostal muscle
Dissection and Rib Spreading
Using scissors, cut the intercostal muscles above the 5th rib to avoid the neurovascular bundle
Temporarily stop ventilation just before exposing the pleura to avoid lacerating the lung
Insert rib spreader with the ratchet placed toward the axilla and handlebar down
Use a Gigli saw, Lebsche knife, or trauma shears to cut the sternum for right-sided exposure
Pericardiotomy
Hold the pericardium with forceps, and use scissors to cut from the cardiac apex to the aortic root (FIGURE 15.2)
The incision should be made anterior and lateral, avoiding the left phrenic nerve
Evacuate blood and clots from the pericardium
Deliver the heart from the pericardium if cardiac repair is required
