Trial Outcomes & Findings for Comparison of Outcomes Between the Use of Silverlon® Dressing and AQUACEL® AG Dressing Post Cardiac Device Implant (NCT NCT02781779)

NCT ID: NCT02781779

Last Updated: 2023-03-10

Results Overview

A pocket hematoma is an accumulation of blood in or near the surgical incision which occurs because of a defect in hemostasis such as injury to blood vessels. Pocket hematoma is associated with local discomfort, an increased risk of infection, and may require surgical intervention or lead to lengthier hospital stays. Mild - Ecchymosis or mild effusion in the pocket, no swelling or pain to device-pocket (watchful waiting) Moderate - Large effusion in the pocket leading to swelling and causing functional impairment or pain to device-pocket Severe - Any pocket hematoma requiring: Reoperation and/or resulting in prolongation of hospitalization (defined as extended hospitalization or rehospitalization for \>24 hours, postindex surgery, primarily due to hematoma) and/or requiring interruption of OAC (defined as reversal or intentional withholding, in response to pocket hematoma, resulting in subtherapeutic anticoagulation for \>24 hours)

Participant Flow

Prospectively enrolled patients undergoing CIED implantation, upgrade, or generator change from June 2016-June 2017 were randomized to receive one of the two dressings at the end of the procedure.

Immunocompromised patients and those on non-standard antibiotic regimens were excluded.

Pocket (Wound) Dehiscence: Dehiscence is a partial or total separation of previously approximated wound edges, due to a failure of proper wound healing. It may be just the surface layer or the whole wound.This scenario typically occurs 5 to 8 days following surgery when healing is still in the early stages.
