Resuscitative Thoracotomy

OVERVIEW

  • resuscitative thoracotomy is a thoracotomy performed prehospital, in the emergency department or elsewhere that is an integral part of the initial resuscitation of a patient
  • an alternate term is emergency thoractomy
  • survival 4-33%
  • determinants of survival include mechanism of injury, the location of injury and the presence or absence of vital signs
  • best outcomes in:

-> penetrating chest
-> those exsaunginating from chest tube
-> isolated chest trauma
-> cardiac injuries
-> abdominal trauma that benefits from aortic clamping
-> time since loss of vitals

REQUIREMENTS

  • ETT
  • shock or arrest with a suspected correctable intrathoracic lesion
  • specific diagnosis (cardiac tamponade, penetrating cardiac lesion or aortic injury)
  • evidence of ongoing thoracic haemorrhage

INDICATIONS

Accepted

  • penetrating injury + arrest + previous signs of life
  • blunt injury + arrest + previous signs of life

Relative

  • penetrating injury + no signs of life and CPR < 15min – blunt injury + signs of life in field or during transport -> arrest 15 min
  • blunt injury + no signs of life
  • multiple blunt trauma
  • severe head injury

RESUSCITATION IN TRAUMATIC ARREST

  • 1. Intubate (reverses hypoxia)
  • 2. Insert bilateral chest drains (or thoracostomies)
  • 3. Resuscitative Thoracotomy
  • 4. Limit fluid as this worsens outcome in penetrating thoracic trauma unless haemorrhage controlled
  • 5. Limit inotropes and pressors until circulation restored (will need once defect repaired)

TECHNIQUE

Goals

  • relieve cardiac tamponade
  • perform open cardiac massage
  • occlude aorta to increase blood flow to heart and brain
  • control life threatening thoracic bleeding
  • control bronchovenous air embolism

1. Full aseptic technique*** –> This was recently an issue where the Trauma attending cited both his team and ours in Rm9 for lack of full prep –> masks, surgical gloves, gowns, etc. should be worn when performing this procedure.
2. Scalpel through skin and intercostal muscles to mid axillary line.
3. Insert heavy duty scissors into thoracostomy incisions.
4. Cut through sternum.
5. Lift up (clam shell)

-> relieve tamponade (longitudinal incision through pericardium)
-> repair cardiac wounds (non-absorbable sutures, 3.0)
-> stop massive lung or hilar bleeding with finger (partial or intermittent occlusion may be performed to avoid right heart failure)
-> identify aortic injuries (repair with 3.0 non-absorbable sutures or use finger)
-> consider aortic cross clamping at level of diaphragm (limits spinal cord ischemia)
