Effect of commonly used surgical solutions on the tensile strength of absorbable sutures: an in-vitro study.

Background: Within recent decades the use of various surgical solutions to prevent bleeding, ward off infection or decrease post-operative pain has become common-place in orthopaedic procedures. However, little work has been done to determine the effects that these solutions have on the tensile strength of various sutures, particularly those that are used for deep closures, which are often absorbable in nature. Whilst numerous authors have attempted to reach conclusions regarding the nature of these effects, a consensus has yet to be reached and this paper is designed with the aim to contribute to the current literature on the subject and improve surgical practice.

Methods: This in-vitro study incubated three different surgical sutures in five commonly used surgical solutions at 37°C for 30 min, prior to applying a constant increase in force to determine the effects these solutions have on tensile strength. A control set was included.

Results: No significant difference was found in the tensile strength of Vicryl and PDS-II sutures, whilst Monocryl incubated in chlorhexidine exhibited a borderline significant increase in tensile strength.

Conclusions: Common surgical solutions used on orthopaedic procedures can impact on the tensile strength of suture materials; however, further research is required on the subject.
