Efficacy of Sternum Guard in Post Cardiac Surgery Patient

Efficacy of Sternum GuardTM in Comparison of Bone Wax in Post Cardiac Surgery Patient: A Single Blind, Single Centre, Randomized Control Trial

This is a single-center, single-blind, randomized parallel superiority trial comparing two groups; Sternum GuardTM as the treatment arm and Bone Wax as the active control group. Both investigated modalities are materials used during sternotomy for covering the sewn sternal edge. The primary outcomes of this study comprised of four parameters; namely surgical site infection (superficial or deep infection), sternal dehiscence, hemostatic effect, and surgeon's satisfaction rate. The first three primary outcomes were assessed during the operation, at the end of the hospital stay, 14 days, and 30-days postoperative.

Detailed Description

A single center randomized controlled clinical trial was conducted at Harapan Kita National Cardiovascular Center, Jakarta, Indonesia as the tertiary cardiovascular referral hospital. The RCT was conducted from May 17th, 2020 until October 20th, 2021 (current status: completed). This study assessed the efficacy of Sternum GuardTM, a commercially-available nonwoven cellulose based, single use, sterile surgical drape used for covering the dissected sternal bone edge during median sternotomy for cardiac surgery. The active comparator/ control group in this study is the use of Bone wax, a vaseline and beeswax-made materials widely used during sternotomy as a mean of bleeding control. The subjects were adults undergoing elective cardiac surgery with median sternotomy approach for any indication. Both the patients and the principal investigators were blinded for the treatment-control allocation, but the surgeon were not blinded for the materials used. The patients were purposively selected and were randomly assigned to one of the arms with block randomization. The primary outcomes of this study comprised of four parameters; namely surgical site infection (superficial or deep infection), sternal dehiscence, hemostatic effect, and surgeon's satisfaction rate. The first three primary outcomes were assessed during the operation, at the end of the hospital stay, 14 days, and 30-days postoperative. The minimum sample size was 414 subjects.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Sternum Guard
The treatment of interest was Sternum GuardTM application during sternotomy.
Other: Sternum Guard

The intervention being assessed is a surgical drape used as a cover of sternal bones and the neighboring structures exposed during median sternotomy named Sternum Guard.

Sternum guard® is a single use, sterile surgical drape with modified cellulose designed specifically to reduce the risk of surgical site infection (SSI).

It is made of 4 parts, the main part is in contact with the retractors and the sternum edge. It is made of carboxymethylated cellulose (CMC) spunlace which makes direct contact with the sternum edges. It contributes to blood absorption, to decreasing of pH environment, and to haemostatic action through a physical effect (compression); another part was made from hydrophilic spunbond (swabs) allowing blood absorption, comfort and protection

Other Names:
  • Sternum GuardTM, Vygon, Netherlands, product code 40.90.11
Active Comparator: Bone wax
The 'bone wax' arm was the control group of active comparator as the widely-used materials during sternotomy.
Other: Bone Wax
patients in this group were given Bone Wax as the hemostatic material during sternotomy. Midline sternotomy with an oscillating saw was conducted after standard aseptic surgical techniques. Bone wax was applied to both spongiosa surfaces of resected sternal bones until bleeding had ceased.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Surgical site infection
Time Frame: within 30 days after the sternotomy surgery performed

A surgical site infection is an infection occurring within 30 days after the operation and only involving the skin and subcutaneous tissue (superficial) or involving deep soft tissues (fibrous connective tissues and muscle layers) of the post-surgical incision wounds.

Superficial surgical site infections is identified by at least one of the following: purulent drainage, organisms isolated from an aseptically-obtained culture of fluid or tissue from the surgical site, presence of signs or symptoms of infection: pain or tenderness, localised swelling, redness or heat, or diagnosis of SSI by the surgeon or attending physician.

A deep incisional SSI is an infection appears to be related to the operative procedure and involves deep soft tissues which is indicated by either; purulent drainage, a deep incision spontaneously dehisces, an abscess, diagnosis of a deep incisional SSI by a surgeon or attending physician.
within 30 days after the sternotomy surgery performed
Haemostatic effect
Time Frame: immediately after the median sternotomy surgery finished
It will assess the quantity of blood lost from the sternal edges in Sternum GuardTM and Bone Wax group. The Sternum GuardTM and sterile drapes will be weighed before and after surgery to estimate the blood lost.
immediately after the median sternotomy surgery finished
Satisfaction rate
Time Frame: within 24 hours after surgery
A rating value from the surgeon as the user of the materials being investigated in terms of satisfaction upon the performance and practicality of the either materials from surgeon's personal opinion.
within 24 hours after surgery
