Pericarditis is inflammation of the pericardium – the outer layer of the heart and pericardial sac. Fluid and inflammation build up around the heart inside the pericardial sac, putting pressure on the heart and making it harder for the heart to fully relax and contract. It can cause heart failure or cardiac tamponade.
Pericarditis is caused by an infectious source, either viral, bacterial, or fungal. Fungal is the least common, while the Coxsackie virus is a common source.
To treat the cause and remove the source of infection while preserving cardiac output and preventing any major (or minor) complications.
Pericarditis Nursing Care Plan
- Chest Pain
- Aggravated by breathing, coughing, swallowing
- Worse when supine
- Symptoms of Heart Failure
- ↑ Temperature
- ↑ WBC
- Signs of Heart Failure
- ST-Elevation possible
- ↓ SpO2
- S/S Cardiac Tamponade
- Muffled heart sounds
- Narrow Pulse Pressure
- Pulsus paradoxus
- JVD with clear lungs
- ↓ Cardiac Output
Nursing Interventions and Rationales
- Assess Heart and Lung Sounds
May hear a pericardial friction rub, muffled heart sounds, or extra sounds because of the pressure being placed on the heart. It’s possible but unlikely that you will hear fluid in the lungs – in cardiac tamponade, the lungs will be clear.
- Assess and Address Oral Hygiene
There is a significant connection between oral health and pericarditis. Bacteria can travel to the heart easily from the oral cavity. Patients should brush their teeth twice daily to prevent complications.
- Administer IV Antibiotics
If the source is bacterial, IV antibiotics will be required to treat the infection. Be sure to obtain blood cultures before initiating antibiotics. If the source is viral – providers may order anti-inflammatory medication since antibiotics aren’t effective. If the virus is known and susceptible, an antiviral medication could be used.
- Perform 3-5 lead ECG monitoring and/or 12-lead ECG
Pericarditis could cause arrhythmias or ST-elevation as the fluid puts pressure on the heart. Cardiac tamponade is a risk – in which case we’ll see the QRS amplitude decrease with inspiration.
Patients will have significant chest pain that is worse with breathing or when supine. Perform OLDCARTS pain assessment and administer pain medication as ordered. Positioning the patient in High-Fowler’s position can also relieve pressure on the heart and be more comfortable for the patient.
- Assess for s/s Cardiac Tamponade
Assess for Beck’s Triad – JVD, ↓ BP, muffled heart sounds. May also see Pulsus paradoxus and narrowing pulse pressures. This is a medical emergency and needs to be treated as such.
- Prepare patient for emergent pericardiocentesis
A physician will insert a large, long needle into the pericardial sac, using ultrasound as a guide, to drain off the fluid that is collecting around the heart. This will allow the heart to beat more freely and should improve cardiac output rapidly.
- Educate patient on s/s infection
Pericarditis is an infectious process, therefore infection control is imperative. They need to be taught hand hygiene as well as other infection precautions. They should also be taught s/s of infection to report to their provider.
- Educate the patient to inform other providers before procedures
- May need prophylactic antibiotics
- No dental procedures for at least 6 months
Because the patient is at high risk for recurrence and complications, they must notify other providers of their history of pericarditis. They may require prophylactic antibiotics before any invasive procedures and they should avoid dental procedures for at least 6 months after their hospitalization.
Cornell Note-Taking System Instructions:
- Record: During the lecture, use the note-taking column to record the lecture using telegraphic sentences.
- Questions: As soon after class as possible, formulate questions based onthe notes in the right-hand column. Writing questions helps to clarifymeanings, reveal relationships, establish continuity, and strengthenmemory. Also, the writing of questions sets up a perfect stage for exam-studying later.
- Recite: Cover the note-taking column with a sheet of paper. Then, looking at the questions or cue-words in the question and cue column only, say aloud, in your own words, the answers to the questions, facts, or ideas indicated by the cue-words.
- Reflect: Reflect on the material by asking yourself questions, for example: “What’s the significance of these facts? What principle are they based on? How can I apply them? How do they fit in with what I already know? What’s beyond them?
- Review: Spend at least ten minutes every week reviewing all your previous notes. If you do, you’ll retain a great deal for current use, as well as, for the exam.
