Effect of Petroleum Gauze Packing on the Mechanical Properties of Suture Materials

Effect of fluid media on the mechanical properties of continuous pattern‐ending surgeon's, square, and Aberdeen knots in vitro*

“…However, to our knowledge, a direct comparison of KHC between dry knots and knots tied immediately after exposure to media has not been performed with large gauge suture. The media studied represent a sample of the fluid components commonly encountered during equine celiotomy . Interestingly, none of the 4‐media evaluated in our study produced a significantly different effect on KHC.…”

“…Multiple studies have analyzed suture material exposed to isotonic or biologic solutions with the aim of determining detrimental effects that exposure over time might have on KHC or tensile strength . Other work has assessed suture material exposed to saline, plasma, fat, and other media designed to recreate the surgical environment to evaluate the effect of these media on the material itself . However, to our knowledge, a direct comparison of KHC between dry knots and knots tied immediately after exposure to media has not been performed with large gauge suture.…”

“…The main limitation of our study is that the materials testing performed was in a single plane of motion and involved a single load‐to‐failure cycle. This is a limitation for any in vitro study of knots using a linear testing model . In the linea alba of a horse recovering from abdominal surgery, the suture and knot would be subjected to tensile forces in multiple planes as well as multiple load cycles.…”

“…Previous publications have noted a significant effect of lubrication on the frictional properties of suture . In small gauge suture (2‐0 polydioxanone), the relative knot security of Aberdeen knots was significantly increased compared to square knots when exposed to plasma and fat .…”

Comparative Evaluation of Chest Tube Insertion Site Dressings: A Randomized Controlled Trial

“…Although the study by Gross et al 5 included petroleum-saturated gauze dressing, this dressing type is no longer recommended for use, as it may be associated with loosening of sutures and maceration of skin. 7 Transparent dressings can be as effective as gauze dressings 4 ; however, transparent dressings and no dressing are not good options for our patients, who typically have large amounts of drainage, especially trauma patients.…”
