Device implantation for patients on antiplatelets and anticoagulants: Use of suction drain

Abstract

Background and objectives: Cardiovascular implantable electronic devices (CIED) are frequently implanted in patients on anti-thrombotic agents. Pocket hematomas are more likely to occur in these patients. The use of a sterile surgical drain in the pulse generator pocket site could prevent hematomas, but fear of infection precludes its use. The objective of the present study is to study the safety and efficacy of surgical drain in patients on antithrombotics undergoing CIED implantations.

Methods: This is a single-centre, retrospective study involving patients undergoing CIED implantations on antithrombotics (antiplatelets and anticoagulants) from August 2013 to July 2016. Patients with high risk of thromboembolism were continued on oral antithrombotics or were bridged with heparin after stopping oral antithrombotics. A sterile close wound suction drain was placed in device pockets following CIED implantations. Post procedure, pressure dressing was applied and removed after 12 h once the drain volume was less than 10 ml in 24 h.

Results: Sixty seven patients required surgical drain implantation. Major indications for antithrombotic use were presence of intracoronary stent, atrial fibrillation and mechanical valve replacements. The mean post-procedural hospital stay was 3 ± 0.9 days and mean overall drain was 16.6 ± 8.2 ml. At a mean follow up of 17.6 ± 8.2 months, one patient (1.4%) had pocket hematoma. There were no infections.

Conclusion: The use of a surgical drain in CIED implantation significantly reduces the risk of hematoma formation without increasing the risk of infection. Antithrombotic drugs can be safely continued at the time of implantation of cardiac devices.
