S-ICD implantation under the serratus plane block and transversus thoracis muscle plane block. A clinical case. / Implantación subcutánea de DCI-S mediante bloqueos del plano del músculo serrato y del músculo torácico transverso. Caso clínico.

INTRODUCTION: The development of a subcutaneous implantable cardioverter-defibrillator (S-ICD) combined with the typical patient comorbidities creates new challenges for anesthesia. CLINICAL CASE: A young male, ASA II, was proposed for S-ICD placement, after recovery from a sudden CRP episode. We performed regional anesthesia with a serratus plane block and transversus thoracic muscle plane block with administration of mepivacaine and ropivacaine. S-ICD placement was achieved under regional anesthesia. In the perioperative period, the patient remained hemodynamically stable, without any complications or pain. DISCUSSION: The implantation of the ICD occurs in fragile patients, with high anesthetic risk. In this case, the association of serratus plane block and transversus thoracic muscle plane block was an effective anesthetic/analgesic approach, has advantages when compared with other techniques and has potential use in other procedures.
