Newly published research in the Journal of Clinical Biomechanics supports using novel devices, such as the SUTUREGARD® ISR Retention Suture Device and the HEMIGARD™ Adhesive Retention Suture Device, to initiate approximation of high-tension surgical wounds.
In the latest issue of the Journal of Clinical Biomechanics, the study “Forces on sutures when closing excisional wounds using the rules of halves”, led by Professor Jay Kruzic, of the University of New South Wales School of Mechanical and Manufacturing Engineering, demonstrated that the average force to close the mid-point of elliptical excisional wounds is, at least, six times more than subsequent closing force of the remainder of the wound when closing linearly.
This prospective, single-center, IRB-approved study evaluated the mid-point force to approximate wound edges with nonabsorbable suture in 18 patients. The average force to close the center of the wounds was six times larger than that of the second and third sutures, which was a statistically significant finding (p <.001). Forces to close the bisected halves were essentially negligible.
This finding has important clinical implications. The authors propose that the goal of closing high tension wounds linearly occurs in two distinct phases: 1) relief of midpoint tension and 2) application of supports to maintain closure.
The SUTUREGARD® ISR Retention Suture Device and the HEMIGARD™ Adhesive Retention Suture Device allows surgeons to initiate approximation of high-tension surgical wounds with suture without damaging the skin. The devices do this by dispersing the pressure of the suture away from the wound edges.
Based in Portland, Oregon, SUTUREGARD® Medical, Inc is a private company offering novel medical devices for surgeons to repair challenging surgical defects more simply. SUTUREGARD® medical devices are intended to provide minimal wound trauma and reduce the healing period after surgery, providing better results for patients.
