The patient with left heart assist device: nursing management
Insights
For patients with poor ventricular performance unresponsive to adjuvant therapy, left heart assist devices (LHAD) offer hemodynamic stability. Specialized nursing care is crucial for managing patients with LHAD, ensuring optimal recovery.
Area of Science:
- Cardiovascular Surgery
- Critical Care Medicine
- Cardiac Assist Devices
Background:
- Adjuvant therapies like positive inotropic agents and pacing are standard for managing poor ventricular performance.
- Intra-aortic balloon counter-pulsation is a temporary measure for hemodynamic support.
- Failure of these interventions necessitates advanced mechanical circulatory support.
Purpose of the Study:
- To highlight the consideration of left heart assist devices (LHAD) when conventional therapies fail.
- To describe the function of LHAD in supporting cardiac output.
- To emphasize the critical role of specialized nursing care in managing patients with LHAD.
Main Methods:
- Review of clinical scenarios where adjuvant therapy is insufficient.
- Description of the mechanism of action for LHAD.
- Outline of essential nursing competencies and responsibilities for LHAD patients.
Main Results:
- LHAD can provide hemodynamic stability by diverting systemic blood flow around the left ventricle.
- This support allows the left ventricle time to recover its pumping function.
- Effective nursing care is paramount for patient outcomes.
Conclusions:
- Left heart assist devices (LHAD) are a viable option for patients with persistent poor ventricular performance.
- Hemodynamic stability is achieved through mechanical circulatory support.
- Highly competent nursing care, including clinical assessment and prompt intervention, is essential for successful LHAD management.
Abstract:
When prolonged use of adjuvant therapy (positive inotropic agents, ventricular or atrial pacing), including intra-aortic balloon counter-pulsation, fails to achieve separation of patients with poor ventricular performance from CPBP the use of LHAD should be considered. The left heart assist device is a means of diverting a moderate portion of the systemic blood flow around the left ventricle. It provides hemodynamic stability until the left ventricle regains is effectiveness and capability as a pump. Nursing care of these patients requires the highest competence in clinical assessment based on a sound knowledge of the interrelatedness of body system and technical support devices. Nursing responsibilities include: careful observation of patient's clinical appearance and behavior, interpretation of data obtained from monitoring equipment, early recognition of physiologic deviations, and prompt initiation of appropriate nursing interventions.
