Subpectoral pacemaker implantation under tumescent local analgesia.

Tumescent local analgesia (TLA) is an anesthetic technique used for inducing local analgesia over large areas and is rarely used in cardiothoracic surgery. An 83-year-old, extremely thin woman was hospitalized with sick sinus syndrome, requiring pacemaker implantation. We chose a subpectoral mode of implantation to prevent skin complications. General anesthesia was deemed risky due to the history of chronic pulmonary disease; therefore, the operation was successfully performed under TLA. Moreover, TLA helped introduce a subpectoral pocket for implanting the pacemaker with minimal trauma and bleeding. The analgesia was sufficient, with minimal postoperative pain, and required no additional sedatives and analgesics. The patient was discharged without any complications.
