S-ICD implantation under the serratus plane block and transversus thoracis muscle plane block. A clinical case.

Introduction: The development of a subcutaneous implantable cardioverter-defibrillator (S-ICD) combined with the typical patient comorbidities creates new challenges for anaesthesia.

Clinical Case: A young male, ASA II, was proposed for S-ICD placement, after recovery from a sudden CRP episode. We performed regional anaesthesia with a serratus plane block (SPB) and transversus thoracic muscle plane block (TTPB) with administration of Mepivacaine and Ropivacaine. S-ICD placement was achieved under regional anaesthesia. 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 anaesthetic risk. In this case, the association of SPB and TTPB was an effective anaesthetic/analgesic approach, has advantages when compared with other techniques and has potential use in other procedures.
