"Fast-tracking" in patients undergoing coronary artery surgery with severely impaired left ventricular function

Area of Science:

• Cardiology
• Anesthesiology
• Cardiac Surgery

Background:

• Early tracheal extubation in cardiac surgery is driven by cost containment and efficient resource use.
• Fast track cardiac anesthesia offers a safe and cost-effective approach.
• Patients with impaired left ventricular function (LVEF ≤ 40%) present unique challenges for early extubation.

Purpose of the Study:

• To evaluate the safety and feasibility of fast track cardiac anesthesia and early extubation in patients with LVEF ≤ 40% undergoing coronary revascularization.
• To assess anesthetic management and operative strategies tailored for patients with reduced ventricular function.

Main Methods:

• Retrospective study of 45 patients with LVEF ≤ 40% undergoing coronary revascularization.
• Anesthetic management focused on reduced narcotic and muscle relaxant use.
• Beating heart surgery was prioritized in patients with low ejection fraction to avoid cardiopulmonary bypass (CPB) effects.

Main Results:

• Early extubation (<4 hours) was achieved in 84% of operative survivors (37/44).
• Only 16% (7/44) required ventilation > 24 hours, primarily due to pulmonary issues or IABP support.
• Intensive Care Unit (ICU) stay < 24 hours was observed in 80.9% (34/42) and hospital stay < 6 days in 60% (24/40).

Conclusions:

• Fast track cardiac anesthesia is safe and effective for patients with impaired left ventricular function.
• Early extubation and reduced resource utilization are achievable in this patient population.
• Tailored anesthetic and operative strategies can optimize outcomes for high-risk cardiac surgical patients.
