심내막염 IV: 간호 관리

Nurses should assess for chest pain, dyspnea (shortness of breath), fatigue, and heaviness in the legs. These non-specific symptoms occur because the heart cannot pump blood efficiently, causing pulmonary congestion and systemic fatigue from the body's inflammatory response to infection.

Objective findings include fever, low oxygen saturation, petechiae (small red spots on skin), splinter hemorrhages (dark streaks under nails), Osler's nodes (painful lesions on finger pads), and Janeway lesions (non-tender lesions on palms and soles). These signs result from microvascular emboli and immune complex deposition caused by the infection.

Nurses should administer prescribed antipyretics such as acetaminophen and provide tepid water baths to reduce body temperature. These interventions address fever, a hallmark sign of the ongoing inflammatory infection process in the heart.

Nurses must regularly auscultate heart sounds to detect new or worsening murmurs, which indicate valve damage or disease progression. Continuous monitoring is critical for identifying early signs of heart failure or embolic events that require immediate intervention.

Nurses should emphasize proper hand hygiene and oral care, including brushing after waking and before bed. Poor dental hygiene can cause bacteremia leading to recurrent endocarditis, so preventive oral practices are essential for reducing infection risk and disease recurrence.

Home health nurses assess peripherally inserted central catheters (PICC lines) used for long-term IV antibiotics and monitor for infection signs including redness, swelling, pain, or drainage at the insertion site. They also educate patients and families about potential complications and ensure adherence to prescribed antimicrobial therapy.

Nurses should encourage moderate exercise with short breaks to improve circulation and maintain muscle tone while avoiding fatigue. Balancing activity with adequate rest helps patients maintain quality of life and perform daily activities without excessive exertion during recovery.
