Indications
- Cardiac tamponade
- Beck's Triad (JVD, Hypotension, Distant heart sounds) - unlikely to have all 3
- Ultrasound
- Pericardial effusion
- Diastolic collapse of the right ventricle
- Diastolic collapse of the right atrium (in atrial diastole)
- Plethoric IVC
- Valvular pulsus parodoxus
- May also see pulsus paradoxus, dyspnea, electrical alternans, low voltage on EKG
- Diagnose cause of pericardial effusion
Contraindications
Emergent procedure - no absolute contraindications in unstable patient
Relative Contraindications[1]:
- For traumatic tamponade, perform ED thoracotomy instead
- Myocardial rupture
- Aortic dissection
- Bleeding diathesis
Equipment
- Pericardiocentesis kit (contains equipment to perform drain placement via Seldinger technique)
- If kit unavailable: 18ga spinal needle, 20mL syringe
- Can also use abdominal paracentesis kit
- Ultrasound if available; or,
- Wire w/ alligator clip connected to base of needle and to any precordial lead of ECG machine
Preparation
- Bed to 45˚ angle if pt condition allows (brings heart/pericardium closer to anterior chest wall)
- NGT if needed to decompress stomach
- Skin prep with iodine or chlorhexidine, followed by sterile drape
- Consider sedation or local anesthesia but do not delay procedure
- Atropine may be helpful to prevent vasovagal reaction
Technique
Subxiphoid Approach[1]
- Identify insertion location between xiphoid process and left costal margin
- Insert needle through skin at identified site at 30-45' angle to the skin, aiming toward left shoulder
- Remove stylet and attach 3-way stopcock and 20-mL syringe
- If utilizing EKG, attach alligator clip from base of needle to any precordial EKG lead
- If utilizing ultrasound, use real-time subxiphoid view to guide needle toward effusion.
- Slowly advance needle while continually aspirating until fluid return
- If utilizing alligator clip, stop advancing needle if ST elevation noted on monitor - withdraw until ST elevations resolve, reposition needle and continue
- Aspirate fluid (even a small amount can significantly improve pt status)
- Disconnect syringe/stopcock and use Seldinger technique to place pericardial drain
- Obtain post-procedure CXR to rule-out iatrogenic PTX
Parasternal Approach[1]
Novel In-Plane Technique[2]
- Skin is prepped
- Curvilinear probe with sterile cover is placed obliquely over the right chest with indicator to the right shoulder
- Depth corrected to see only the RV and effusion
- Needle directed in an in-plane approach at 45°
- Aspiration is done under direct needle visualization
- A catheter can be placed under direct visualization using Seldinger technique
Complications
- Cardiac puncture/hemopericardium
- Pneumothorax/pneumopericardium
- Dysrhythmias
- PVC (most common)
- Vasovagal bradycardia (responsive to atropine)
- False negative (clotted pericardial blood)
- False positive (intracardiac puncture)
