Technique presentation: The combination of Pectoralis and Serratus Plane Nerve Blocks for cardiac implantable devices

Abstract

Cardiac resynchronization therapy devices, implantable cardioverter defibrillators, and pacemakers are used to treat advanced systolic heart failure, ventricular tachyarrhythmias, and bradyarrhythmia. Over the past ten years, there has been a notable rise in the number of cardiac implanted electronic device implants because of mounting evidence of better survival and quality of life among specific patient populations. Appropriate analgesia and sedation throughout the implantation procedure is crucial for the patient’s stability. This paper aims to describe the advantages of both interpectoral plane block (PECS I) and interpecto-seratus plane block (PECS II) for the implantation of cardiac devices. Combining PECS I and PECS II blocks provides advantages for the thoracic wall procedures. While the PECS I block anesthetizes the medial and lateral pectoral nerves, PECS II extends coverage to upper intercostal nerves (T2-T7), as well as the long thoracic and thoracodorsal nerves, covering areas that are not anesthetize adequately by PECS I alone. Minimizing the need for opioids, leading to fewer opioid related side effects contributing to shorter recovery time and nonetheless creating less discomfort for the patient. This combined regional technique offers comfort to the patient due to its sole puncture needed for performance and by offering an extensive anesthesia at the site of the procedure.
