It is known that 105 bacteria in 1 g of tissue is sufficient to induce I-SSI. Incisional SSI (I-SSI) is still a frequent postoperative adverse event jeopardizing patient safety and increasing healthcare costs.
SSI leads to increased overall healthcare costs and is associated with a prolonged hospital stay, more complex wound care needs, more frequent visits to outpatient clinics, and higher rates of hospital readmission and morbidities.SSI is associated with a mortality rate of 3%, and 75% of SSI-associated deaths are directly attributable to SSI.
There are independent risk factors for I-SSI, and intraoperative wound management is one of the most important to reduce them. The following improve intraoperative wound management:
Clinical Background
Antibiotic prophylaxis.
Skin preparation.
Skin drape.
Operative double gloving.
Body temperature.
Wound length.
Subcutaneous lavage before closure.
Subcutaneous drainage.
Skin suture methods (subcuticular absorbable suture).
Skin wound dressing.
Technique Description
Conventional surgical drapes are commonly used by surgeons to limit the aseptic surgical area and to cover the freshly-made wound edges.
This non-fixed mechanical barrier may become dislodged or potentially contaminated. New devices have appeared to overcome this problem and for wound-edge isolation.
These new surgical devices are based on a non-adhesive plastic sheath attached to a single or double rubber ring that firmly secures the sheath to the wound edges. They also provide extra incision retraction, which reduces the need for mechanical retractors.
They are used to reduce wound edge contamination during abdominal procedures including contamination from the outside (clean surgery) and inside the peritoneal cavity (clean contaminated, contaminated and dirty).
A recently conducted meta-analysis of RCTs evaluated whether various types of wound protectors can reduce the risk of SSI.
Using wound protectors, the risk of SSI was 0.55 times the pooled estimated risk of SSI in control groups (95% CI 0.31 to 0.98).
When analyzing the reduction of SSI based on the type of surgery, it is beneficial in reducing the SSI rate when compared to standard wound protection in clean contaminated (OR: 0.63; 95% CI: 0.4–0.99) and contaminated (OR: 0.31; 95% CI: 0.15–0.64) procedures.
In the dual-ring versus single-ring comparison, the pooled estimated risk of SSI was 0.31 (95% CI 0.14 to 0.67).
SSI is still a frequent postoperative complication with significant overall healthcare costs and high rates of hospital readmission and morbidity.
Intraoperative wound management is one of the most important factors to reduce SSI.
Wound protectors have evolved to improve the limitations of the aseptic area and reduce SSI.
Dual-ring wound protectors have shown better outcomes when compared with single-ring ones.
The latest guidelines recommend the use of wound protectors for the prevention of SSI.
