Final answer:
Mitral stenosis is a condition in which the mitral valve becomes narrow and rigid, impeding blood flow. Anesthetic considerations, fluid strategy, hemodynamically significant valve surface area, and monitoring are all important aspects to consider in managing mitral stenosis.
Step-by-step explanation:
Mitral stenosis is a condition in which the mitral valve becomes rigid and narrowed, impeding the flow of blood from the left atrium to the left ventricle. Anesthetic considerations for mitral stenosis include avoiding drugs that reduce systemic vascular resistance, maintaining sinus rhythm, and closely monitoring hemodynamic parameters. Fluid strategy involves careful administration of fluids to maintain adequate preload and avoid fluid overload. Hemodynamically significant valve surface area is the threshold at which surgical intervention may be necessary, usually around 1.0 cm^2. Monitoring during mitral stenosis may include continuous ECG, invasive arterial blood pressure monitoring, central venous pressure monitoring, and transesophageal echocardiogram.
