Monitor-guided responses. Operability with safety is increased in patients with peripheral vascular diseases

Area of Science:

• Cardiology
• Anesthesiology
• Geriatric Medicine

Background:

• Elderly patients undergoing elective vascular reconstruction often have undiagnosed cardiopulmonary reserve issues.
• Conventional clinical evaluations may underestimate the severity of left ventricular dysfunction (LVF) and associated surgical risks.

Purpose of the Study:

• To evaluate the utility of the automated physiologic profile (APP) in assessing cardiovascular hemodynamics in elderly patients before vascular surgery.
• To identify patients with compromised left ventricular function (LVF) who require perioperative optimization.

Main Methods:

• Cardiovascular hemodynamics of 75 elderly patients were analyzed using the automated physiologic profile (APP) preoperatively.
• Patients were categorized based on left ventricular function (LVF) and hemodynamic needs.

Main Results:

• Only 33.3% of patients had normal left ventricular function (LVF); 40% required significant pharmacologic and preload adjustments.
• The APP identified subtle physiologic abnormalities missed by conventional methods, guiding anesthetic and operative modifications.
• Perioperative optimization was successful in nearly all patients, with only one denied surgery.

Conclusions:

• The automated physiologic profile (APP) is a valuable tool for preoperative assessment of cardiovascular hemodynamics in elderly surgical patients.
• APP-guided optimization significantly improves perioperative outcomes and patient selection for vascular reconstruction.
• Early identification and management of left ventricular dysfunction (LVF) are crucial for reducing morbidity and mortality in this population.
