1. End-of-service with pacemaker generator.
2. Pacemaker dependent.
POSTOPERATIVE DIAGNOSIS:
1. End-of-service with pacemaker generator.
2. Pacemaker dependent.
PROCEDURE: Pacemaker generator replacement.
ANESTHESIA: Monitored anesthesia care plus local.
ESTIMATED BLOOD LOSS: None.
INDICATIONS: The patient is a very pleasant 88-year-old gentleman status post initial single-chamber ventricular pacemaker insertion 01/10/96, and status post pacemaker generator replacement 02/12/02, where recent testing found that the pacemaker was at elective replacement interval. He is pacemaker dependent. He was referred for pacemaker generator replacement. The indications, risks, benefits of procedure were explained to the patient as well as to his wife and neice. He understood and consented for the operation.
FINDINGS: The explanted pacemaker is a St. Jude Medical model #5136, serial #605300. The chronic right ventricular lead is a St. Jude Medical model # 1246, T/58, serial #CB18308. The implanted pacemaker is a St. Jude Medical Zephyr XL SR, single chamber rate responsive pacemaker, model #5626, serial #1984162. Pacing parameters for the right ventricular lead, R-waves were not measured as he is pacemaker dependent, impedance 648 ohms, and pacing threshold 0.4 volts.
PROCEDURE IN DETAIL: A time-out was performed prior to start of the operation. The patient was correctly identified as well as the procedure. With the patient under monitored anesthesia care, the patient's left upper chest and neck were prepped with DuraPrep and draped sterilely. A 1% Xylocaine was infiltrated locally over the more superior of the two pacemaker scars. The pacemaker scar was incised. The subcutaneous tissues were divided with electrocautery. The fibrous capsule surrounding the pacemaker generator was opened and the pacemaker explanted. The lead was loosened and removed from the pacemaker generator and quickly attached to the pacemaker cable for pacing and testing, as the patient is pacemaker dependent. Pacing parameters were excellent. The lead was then inserted into the receptacle of the pacemaker generator and tightened down.
The pocket was irrigated with antibiotic solution. Hemostasis was fine. The generator was inserted into the pocket. The incision was closed in layers with continuous Vicryl sutures including the subcuticular layer. Dermabond and a Coverlet were applied.
The patient tolerated the procedure well and there were no complications. Sponge, instruments, and needle counts were correct. The patient was transported to the post anesthesia care unit in stable condition.
