[Anesthetic management using HemoSonic 100 in a patient with chronic renal failure and dilated cardiomyopathy]

Area of Science:

• Cardiology
• Anesthesiology
• Nephrology

Background:

• Anesthetic management for nephrectomy in patients with comorbidities like chronic renal failure and dilated cardiomyopathy (DCM) presents unique challenges.
• Utilizing advanced monitoring is crucial for maintaining hemodynamic stability during complex surgical procedures.

Observation:

• A patient with chronic renal failure and DCM underwent nephrectomy under anesthesia.
• Propofol, ketamine, and fentanyl were used for anesthesia induction and maintenance.
• Left ventricular ejection time (LVETc) was monitored using HemoSonic 100.

Findings:

• Active bleeding from the renal artery led to a decrease in LVETc.
• LVETc provided critical data for assessing adequate preload and guiding transfusion rates.
• The HemoSonic 100 proved valuable in managing the patient's circulatory condition.

Implications:

• HemoSonic 100 serves as a useful tool for anesthetic management in patients with DCM, particularly for preload assessment.
• This case highlights the importance of continuous hemodynamic monitoring in high-risk surgical patients.
• Effective anesthetic strategies can lead to successful surgical outcomes even in patients with significant comorbidities.
