Closely monitor vital signs, including blood pressure, heart rate, and respiratory rate, at least every 15 minutes during the initial infusion and then adjust frequency based on patient stability. Regularly assess for orthostatic hypotension, especially in elderly patients.
Electrolyte Monitoring
Obtain baseline serum electrolytes (sodium, potassium, chloride, magnesium) before starting Lasix and frequently thereafter, as hypokalemia and other electrolyte imbalances are potential risks. Adjust electrolyte levels proactively as needed.
Fluid Balance Assessment
Monitor intake and output (I&O) meticulously. Compare urine output to the previous hour’s fluid intake. Pay attention to changes in weight daily and assess for signs of dehydration.
Renal Function Monitoring
Regularly assess renal function via serum creatinine and blood urea nitrogen (BUN) levels. Note any deterioration of renal function; reduce dosage or discontinue Lasix accordingly. Consider serum creatinine level changes over time to effectively monitor renal function. Reduce dose if creatinine level increases significantly.
Other Considerations
Observe the patient for signs and symptoms of dehydration (e. g., dry mucous membranes, decreased skin turgor, oliguria), and dizziness or lightheadedness. Adjust the rate of infusion based on patient response and regularly reassess the need for the medication.
