[New approach for defibrillation after cardiac reoperation]

Area of Science:

• Cardiovascular Surgery
• Medical Devices
• Electrophysiology

Background:

• Cardiac reoperations carry significant risks, including ventricular arrhythmias, which increase perioperative mortality.
• Defibrillation is often delayed until after pericardial dissection, limiting its effectiveness in critical moments.

Purpose of the Study:

• To evaluate the efficacy and benefits of using self-adhesive electrode pads for external defibrillation during cardiac reoperations.
• To assess the impact of this system on perioperative complications and surgical outcomes.

Main Methods:

• Prospective study involving 132 patients undergoing cardiac reoperation over six months.
• Utilized self-adhesive electrode pads placed on the cardiac apex and infrascapular area, connected to standard defibrillators.
• Monitored for defibrillation events, complications, blood loss, transfusion requirements, and operating time.

Main Results:

• Eighteen of 132 patients (14%) required intraoperative defibrillation, successfully managed with the electrode pads.
• The system facilitated early defibrillation, even with adhesions, and did not impede the surgical field.
• Observed benefits included reduced dissection, decreased blood loss and transfusions, and shorter operating times.

Conclusions:

• Self-adhesive electrode pads are effective and safe for external defibrillation during cardiac reoperations, mitigating risks associated with arrhythmias.
• The system offers significant advantages, including improved patient safety, reduced surgical invasiveness, and enhanced efficiency.
• Continued use of pads post-operatively aids in managing emergent arrhythmias, further improving patient care.
