Trauma: Thoracic Incisions
Median Sternotomy
Access
- Anterior Mediastinum
- Heart
- Innominate Artery
- Proximal Common Carotid Arteries
- Proximal Right Subclavian Artery
- Limited Exposure of the Left Subclavian Artery
Technique
- Vertical Incision Centered Over the Sternum
- Carry Down onto the Anterior Sternum
- Superiorly
- Incise the Interclavicular Ligament
- Digitally Clear the Tissue from the Posterior Manubrium
- Inferiorly
- Clear Tissue Off the Xiphoid Process
- Digitally Clear the Tissue from the Posterior Xiphoid/Sternum
- May Require Division or Excision of the Xiphoid
- Divide the Sternum
- Use Sternal Saw or Lebsche Knife
- Other Options: Bone Cutter or Trauma Shears
- Great Care to Stay in Midline – Closure Significantly Complicated if Off Midline
- Use Sternal Saw or Lebsche Knife
- Use a Finochietto Retractor to Open the Space
Median Sternotomy
Thoracotomy
Resuscitative Thoracotomy
- Anterolateral Left Thoracotomy Through the Fifth Intercostal Space
- *See Trauma: ED Resuscitative Thoracotomy
Bilateral “Clamshell” Thoracotomy
- Bilateral Anterolateral Thoracotomies Through the Fifth Intercostal Spaces
- Sternum is Transected with a Lebsche Knife, Rib Cutter, Trauma Shears or Gigli Saw
- Provides Excellent Access to the Mediastinum, Great Vessels & Hilar Structures Bilaterally
- Internal Mammary Arteries Must Be Identified & Ligated if Cardiac Output is Regained – Division Can Cause Significant Blood Loss
Posterolateral Thoracotomy
- Generally Avoided in Trauma
- Only Considered in Stable Patients if Other Life-Threatening Injuries are Ruled Out
- Can Provide Superior Access to Lateral & Posterior Wounds
Resuscitative Thoracotomy
Supraclavicular Incision
Access
- Mid-Distal Subclavian Artery
- Vertebral Artery (Segment V1)
Technique
- Incision Parallel & 1 cm Above the Clavicle
- Carried Down Through Platysma
- Divide the Clavicular Attachment of the SCM to Expose the Internal Jugular Vein & Scalene Fat Pad
- Divide the Anterior Scalene Muscle to Expose the Subclavian Artery
- Anterior Scalene Lies Between the Subclavian Vein & Artery
- Preserve the Phrenic Nerve Coursing Obliquely Over the Muscle
- Vertebral Artery (Segment V1) Can Be Identified Around the Medial Portion of the Subclavian Artery
Clavicular Resection
- May Require Addition of Median Sternotomy to Improve Proximal Access
- Incision: Over the Anterior Surface of the Clavicle from the Sternoclavicular Junction to the Mid-Clavicle & Down Over the Deltopectoral Groove
- Clear Circumferentially of All Tissues
- Use Gigli Saw to Divide in the Mid Portion
- Dissect the Sternal Head Free to Remove the Clavicle
- Can Replace Clavicle When Done (But Not Mandatory)
