Endocarditis: Definition, Causes, and Symptoms00:00:43
Endocarditis is defined as inflammation of the inner lining and valves of the heart, often characterized by bacterial vegetation buildup. Causes include IV drug use, valve replacements, and poor oral health. Symptoms involve fever, increased white blood cell count, heart murmurs, and signs of heart failure. Critical complications arise from embolisms, such as stroke, myocardial infarction (MI), and pulmonary embolisms (PEs). Other signs include splinter hemorrhages, Janeway lesions, and clubbing of fingers.
Nursing Interventions for Endocarditis00:04:23
Treatment for endocarditis focuses on antibiotics, sometimes for as long as six weeks, stressing the importance of oral hygiene, anti-embolic stockings, anticoagulants, and strict infection control measures. Patient education is also critical.
Pericarditis: Definition, Causes, and Complications00:05:37
Pericarditis is inflammation of the pericardial sac surrounding the heart, which can lead to fluid buildup and stiffness, impairing heart function. It can be caused by viral (e.g., coxsackievirus), bacterial, or fungal infections. Complications include heart failure, cardiogenic shock, and cardiac tamponade, where excessive pressure prevents the heart from beating effectively.
Pericarditis: Symptoms and Beck's Triad00:07:26
Symptoms of pericarditis include fever, increased white blood cells, signs of heart failure (low cardiac output), and chest pain, which worsens with breathing, coughing, or lying flat. Cardiac tamponade is identified by Beck's triad: jugular vein distention (JVD), decreased blood pressure, and muffled heart sounds. Other signs include pulsus paradoxus and a narrowed pulse pressure.
Nursing Interventions for Pericarditis00:09:03
Treatment for pericarditis involves antibiotics for bacterial cases, supportive care for viral infections, anti-inflammatory medications (steroids, NSAIDs), pain management, oxygen administration, and positioning patients in high Fowler's. In cases of cardiac tamponade, a pericardiocentesis is performed to drain fluid around the heart, often providing immediate symptom relief.
Key Nursing Concepts and Summary00:10:34
Major nursing concepts for both conditions include maintaining perfusion, infection control, and health promotion through patient education. Patients need to understand signs and symptoms of infection and emboli, precautions to take, and when to report to their providers. The lesson concludes by recapping that endocarditis is inner heart lining/valve inflammation, and pericarditis is outer heart lining inflammation, both sharing common symptoms like infection signs, decreased cardiac output, and chest pain, requiring specific treatments and preventative measures.

The video introduces endocarditis and pericarditis, breaking down their names to reveal their meanings: inflammation inside the heart (endocarditis) and around the heart (pericarditis).
