Questions: After reading the operative report below, provide a complete response and codes to the questions that follow.

Findings: The patient had a superficial wound dehiscence with exposure of his leads. He had a small area of lead fraying on lead one. After the leads were freed up from the scar and the pocket, that showed one area of lead dropout on interrogation.

The patient was taken to the operating room and placed in the supine position. General endotracheal anesthesia was obtained. The patient had the usual monitors placed. The patient was then rolled prone onto the Jackson OSI table. All of the soft tissue areas were well padded. The patient had the usual monitors placed. He then had the chest wound for the new generator site identified with the incision identified using C-arm fluoroscopy in the AP plane and the course of the lead was followed and the lead was planned to be explanted at a new level and then reconnected to the generator, which would be disconnected from the lead to the present location pocket. The patient had a timeout done per protocol confirming the correct patient, correct procedure, and all equipment that was necessary from the Boston Scientific pacemaker rep. The patient then had the incisions injected with local and the initial incision was made over the area where the generator was.

Sharp dissection was used to get down to the generator layer, and bipolar cautery was used for hemostasis. The leads were dissected free from the superficial aspect of the incision and then the area of the generator was exposed, and the generator was explanted and then it was disconnected from the leads, and the temporary stoppers were placed in the lead holes on the generator and secured and then the generator was placed in antibiotic solution. The area of the leads was then inspected and noted to be markedly scarred in the pocket where they had been positioned behind the generator. These were dissected free using the Bovie cautery on cutting mode and, once the leads had been freed up from all the scar, the new pocket was made hemostatic and was irrigated out. The leads were then exposed through the other incision for the new generator site. This was placed approximately 5 in. above the present site and then, once the leads had been identified in the depth of the new incision, they were mobilized and dissected free and then mobilized up to the new incision and then wrapped in an antibiotic soaked lap.

The new pocket was created using a Bovie cautery and the Army-Navy retractors and, once hemostasis was obtained using the suction cautery, the area was irrigated out and then the old generator site was irrigated out. Then the generator was brought up after we had changed our gloves on the field and then the generator had the stoppers removed and the leads were then placed in their usual positions. The generator was placed halfway in the pocket and then interrogated by the Boston Scientific rep, and the #1 lead was noted to have one area of dropout but otherwise was functioning well. This was consistent with a small area of fraying of the lead with the bulk of the lead intact. The leads were then tightened and then reinterrogated with otherwise good function noted, normal impedances, and then the excess lead was placed behind the generator in the pocket. Then the pocket was irrigated out again with Vancomycin antibiotic solution and, once both pockets had been irrigated out, the wound was closed in multiple layers and the skin was ultimately closed with staples at both sites. The patient then had the wounds cleaned off and dressed and the patient was then rolled supine and extubated and brought back to the recovery room alert and moving all extremities.

• Based on your review of the operative report, what is the objective of the procedures performed today?
