Detailed Description
Demand for Total Knee Arthroplasty (TKA) and Total Hip Arthroplasty (THA) is increasing steadily and is projected to continue trending upwards in the coming years. Postoperative infections are a common but also potentially devastating complication of total joint arthroplasty.
Various strategies are employed both pre-operatively and post-operatively to prevent this complication. A 2011 Cochrane Review concluded that Iodine impregnated adhesive drapes had no impact on surgical site infection rate when used in various surgical procedures not specific to orthopaedics. The recent SSI prevention guidelines by the World Health Organization did not find any evidence to support the use of adhesive drapes during surgery and recommends against its use.
Currently, iodine impregnated adhesive drapes in conjunction with either chorahexadine gluconate or Iodine Povacrylex and Isopropyl Alcohol are the standard of care at our institution.
FloraSeal is a cyanoacrylate-based sealant. A cyanoacrylate microbial sealant minimizes endogenous bacteria spread to the surgical site by forming a sterile film bonded onto a patient's skin. This film, which is formed upon polymerization, prevents the spread of microorganisms. The protective mechanism is mechanical: the film traps and immobilizes microorganisms that survive on a patient's skin. It has been previously shown to effectively immobilize both gram positive and gram negative bacteria. Additionally, the sealant itself can effectively reduce the superficial bacterial burden on the skin surface and also helps reduce skin moisture buildup on skin.
Furthermore, with conventional adhesive drapes, the edges must be peeled back at the time of skin closure in order to effectively close the surgical site. It is at this moment that the incision becomes most vulnerable to penetration by local microorganisms. FloraSeal and other cyanoacrylate based sealants remain on the skin for 5 to 10 days until the superficial skin sloughs off.
Studies on sterile pig skin demonstrated FloraSeal to be more effective alone at immobilizing bacteria than incisional drapes. The efficacy was the same when FloraSeal was used with or without the incisional drapes, demonstrating that it may be used as a substitute.
Additionally, a 2013 retrospective study in revision shoulder arthroplasty demonstrated a potential reduction in positive intraoperative deep tissue cultures when using a cyanoacrylate-based microbial sealant versus the iodine impregnated incisional drapes. The study lacked sufficient power to reach significance, calling for further investigation of this effect.
Cyanoacrylate has been investigated in other surgical interventions. A 2008 prospective, randomized multicenter clinical trial in patients undergoing elective open hernia repair demonstrated cyanoacrylate-based microbial sealant independently reduced wound contamination over the course of the operation.
Due to the potentially devastating complications associated with postoperative infection, the investigators seek to find alternative methods of prevention of surgical site infection.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
EXPERIMENTAL: Floraseal
The surgical site will first be cleaned with isopropyl alcohol.
Once the site is dry, alcohol based chlorhexidine gluconate preparatory solution will be applied to the surgical site.
Once dry, the FloraSeal surgical preparatory solution will be applied per the manufacturers recommendations.
The extremity will be draped in sterile fashion however adhesive drapes over the surgical site itself will not be applied.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Appearance of Surgical Site
Time Frame: 90 days from date of surgery
|
The surgical incision will be checked post-operatively for signs of infection or dehiscence.
|
90 days from date of surgery
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Intra-operative cultures
Time Frame: Intra-operative - Cannot be clearly defined as it will depend on the duration of the surgical procedure.
|
Five wound cultures will be obtained at various points during the operation to test for contamination of the surgical site
|
Intra-operative - Cannot be clearly defined as it will depend on the duration of the surgical procedure.
|
Post-operative complication - Antibiotic administration
Time Frame: 90 days from date of surgery
|
Some surgical site infections may be managed with either intravenous or oral antibiotics.
Both groups will be followed to see if either required antibiotic administration.
|
90 days from date of surgery
|
Post-operative complication - Re-operation
Time Frame: 90 days from date of surgery
|
Some surgical site infections require surgical debridement.
Patients will be followed to determine which patients require re-operation.
