Procedures l.jpg

Procedures

Intermediate Format:

Pericardiectomy/Pericardial Window


Objectives l.jpg

Objectives

  • Assess the related terminology and pathophysiology of the heart.

  • Analyze the diagnostic interventions for a patient undergoing a pericardiectomy.

  • Plan the intraoperative course for a patient undergoing_____________.

  • Assemble supplies, equipment, and instrumentation needed for the procedure.


Objectives3 l.jpg

Objectives

  • Choose the appropriate patient position

  • Identify the incision used for the procedure

  • Analyze the procedural steps for pericardiectomy.

  • Describe the care of the specimen


Terms and definitions l.jpg

Terms and Definitions

  • Pericardium

  • Decortication

  • Pericardial effusion

  • Cardiac tamponade


Definition purpose of procedure l.jpg

Definition/Purpose of Procedure

  • Partial excision of adhered, thickened fibrotic pericardium to relieve constriction of compressed heart and large blood vessels

    • For heart surgery

  • Possibly cardiac bypass on standby

    • Supine, arms on armboards at 90 degrees

  • Supplies and equipment

  • Special considerations: high risk areas


Surgical intervention special considerations incision l.jpg

Surgical Intervention: Special Considerations/Incision

  • Special considerations

  • State/Describe incision

    • Median sternotomy

    • # 10, # 15 blades


Surgical intervention supplies l.jpg

Surgical Intervention: Supplies

  • General: Cardiac pack

  • Specific

    • Suture

      • 4-0 & 5-0 Prolene, wire for sternum

      • Pledgets

    • Medications on field (name & purpose)

      • Heparinized saline solution and other meds as indicated on preference card (may have protamine on standby)

    • Catheters & Drains: Chest Tubes


Surgical intervention instruments l.jpg

Surgical Intervention: Instruments

  • General: Chest and Heart sets

  • Specific

    • Have all cardiac bypass instrumentation available if needed


Surgical intervention equipment l.jpg

Surgical Intervention: Equipment

  • General

  • Specific

    • Cardiac defibrillator on standby with internal and external paddles

    • Cardiac bypass on standby


Surgical intervention procedure steps l.jpg

Surgical Intervention: Procedure Steps

  • The lungs are displaced laterally, and the right and left phrenic nerves are identified and protected

  • The pericardium is incised

  • Decortication begins with the left ventricle

    • To prevent development of pulmonary edema and Rt Side Heart Failure, which could happen if one starts w/right ventricle

  • A plane is developed between parietal & visceral pericardium

    • Caution must be taken to prevent calcified portions of the parietal pericardium from penetrating the heart’s chambers, esp the atria.

  • The outer, thickened pericardium is removed as indicated

    • Have cartilage scissors ready


Surgical intervention procedure steps15 l.jpg

Surgical Intervention: Procedure Steps

  • Fibrous portions adhering to the atria and ventricles are carefully dissected w/dry dissectors and scissors

    • Extreme caution used to prevent perforation of atria and right ventricle—small areas of adherent pericardium may be retained

    • STSR is prepared with loaded 4-0 or 5-0 pledgeted Prolene sutures.

  • Dissection is continued; large blood vessels are exposed and freed as needed; the Atria, Ventricles, and both Cavae are freed

  • Drainage catheters are placed near the heart or through the pleural spaces

    • STSR has chest tubes ready with closed drainage system

  • Sternum is closed w/ stainless steel wire, and remainder of wound closed “usual manner”


Counts l.jpg

Counts

  • Initial: Sponges, Sharps, instruments

  • First closing

  • Final closing

    • Sponges

    • Sharps

    • Instruments
