Brief Summary

Pocket hematoma is a known complication of pacemaker (PM) implantation. Pocket hematoma is accompanied by a local discomfort associated with the infiltration of subcutaneous tissue. In some cases, this complication requires repeated surgical revisions, which increases the risk of infection, and increases the duration of a hospital stay. The search for ways to prevent bleeding from the PM pocket is of great practical interest. This question is especially acute in relation to patients who are constantly on anticoagulation and/or antiplatelet therapy. A number of authors propose to carry out complete or partial cancellation of these drugs for the period before surgery and in the early postoperative period. In our opinion, this approach in most cases carries a potential risk to the health of patients, especially in the case of patients who have previously undergone surgical correction of valve insufficiency and/or who have undergone percutaneous endovascular interventions. The use of local hemostatic drugs is one of the promising directions for increasing the efficiency of intraoperative hemostasis. The haemostatic solution "Haemoblock" has shown its hemostatic potential in general surgical practice. The possibilities of "Haemoblock" in the prevention of pocket hematoma have not been studied. The hemostatic effect of "Haemoblock" is achieved within 1-2 minutes due to the formation of a clot with blood plasma proteins, first of all with albumin. As a result of the action of the "Haemoblock", a strong polymethacrylate membrane is formed on the surface of the wound, which, among other things, has a bactericidal effect.

Outcome Measures

Primary Outcomes (1)

  • The presence of free fluid (blood) in the pacemaker pocket in the early postoperative period, diagnosed by ultrasound.

    Ultrasound of pacemaker pocket to diagnose pocket hematoma will be performed in all patients. The presence of a hematoma (fluid) in the pacemaker pocket before the ultrasound can be verified after examination by the surgeon by the detection of palpable infiltration, smoothing the pacemaker contour, the presence of a fluctuation effect.

    Up to 30 days after pacemaker implantation.

Secondary Outcomes (5)

  • Drainage installation during surgery.

    During surgery.

  • Hematoma drainage duration.

    Up to 7 days after pacemaker implantation.

  • Imbibition of soft tissues near pacemaker pocket.

    Up to 30 days after pacemaker implantation.

  • Exceeding the average length of hospital stay.

    Up to 30 days after pacemaker implantation.

  • Pacemaker implantation complications and cardiac events (stroke, transient ischemic attack, bleeding, pericarditis, cardiac tamponade, infection).

    Up to 30 days after pacemaker implantation.
