  Purpose
Surgical site infection (SSI) after breast and axillary surgery occurs more often than for other clean surgical procedures. Infection in the setting of a tissue expander can be devastating and can lead to early implant loss and failed reconstruction. Surgical drains have been noted as a potential source for surgical site infections. Hypothesis: Bacteria present in surgical drains after tissue expander reconstruction may be decreased by simple and inexpensive local antiseptic interventions.

Nonmalignant Breast Conditions Breast Cancer Device: Sodium hypochlorite (Dakin's Solution) Device: Chlorhexidine gluconate disk Procedure: Control Device: Occlusive Adhesive Dressing Phase 2

Primary Outcome Measures:
  • Number of Subjects With Drain Bulb Fluid Bacterial Colonization at Approximately 1 Week [ Time Frame: Approximately 1 week after surgery ]
    Bacterial growth was defined as plate growth of 1+ or greater. Drains were removed at variable times across patients, per clinical indication. When clinically indicated, some patients did have their drains removed at the one week visit, in which case they only had one bulb fluid culture.

  • Per Drain Analysis: Drain Bulb Fluid Colonization at Approximately 1 Week [ Time Frame: Approximately 1 week after surgery ]

Secondary Outcome Measures:
  • Number of Subjects With Drain Tubing Colonization at Removal [ Time Frame: Approximately two weeks after surgery ]
    Drain tubing colonization was defined as greater than 50 colony forming units. Drains were removed at variable timepoints based on the clinical situation.

  • Number of Subjects With Drain Bulb Fluid Bacterial Colonization at Removal [ Time Frame: Approximately 2 weeks after surgery ]
    Bacterial growth was defined as plate growth of 1+ or greater. Drains were removed a variable times across patients, per clinical indication. A second bulb culture was obtained later than 1 week ONLY in those drains that were not removed at 1 week.

  • Number of Subjects With Surgical Site Infection Within 30 Days [ Time Frame: Approximately 30 days after surgery ]
  • Number of Subjects With Surgical Site Infection Within 1 Year [ Time Frame: Approximately one year after surgery ]
  • Per Drain Analysis: Drain Tubing Colonization at Removal [ Time Frame: Approximately one month after surgery ]
  • Per Drain Analysis: Drain Bulb Fluid Colonization at Removal [ Time Frame: Approximately one month after surgery ]

Arms Assigned Interventions
Experimental: Antisepsis Side
A chlorhexidine gluconate disk (BioPatch) covered by an occlusive adhesive dressing (Tegaderm) will be applied to the intervention drain sites and changed every three days. The drainage bulb will be irrigated with 10ml of 0.125% sodium hypochlorite (Dakin's solution) twice a day.
Device: Sodium hypochlorite (Dakin's Solution)
10 ml of 0.125% sodium hypochlorite (Dakin's solution) irrigation to the drainage bulb two times a day
Other Names:
  • Dakin's solution
  • Wound cleanser
Device: Chlorhexidine gluconate disk
Apply one chlorhexidine disk to the intervention drain site(s) and change every three days
Other Name: BioPatch Protective Disk with CHG
Device: Occlusive Adhesive Dressing
A chlorhexidine gluconate disk (BioPatch) covered by an occlusive adhesive dressing (Tegaderm) will be applied to the intervention drain sites and changed every three days.
Other Name: Tegaderm CHG Dressing
Control Side
Standard drain care will be performed twice a day or three times if bulb is full and needs to be emptied. Standard drain care consists of stripping the tubing, emptying the drainage bulb, recording the volume of fluid, and cleaning the drain site with a cotton swab dipped in rubbing alcohol. The drain exit will be covered with a dry sterile gauze dressing and changed after each episode of drain care.
Procedure: Control
Standard drain care will be performed twice a day or three times if bulb is full and needs to be emptied. Standard drain care consists of stripping the tubing, emptying the drainage bulb, recording the volume of fluid, and cleaning the drain site with a cotton swab dipped in rubbing alcohol. The drain exit will be covered with a dry sterile gauze dressing and changed after each episode of drain care.

Detailed Description:

Surgical Site infection after breast surgical procedures occurs more frequently than for other clean surgical procedures. Considering the large numbers of patients who undergo breast-related procedures per year and the increasing use of immediate breast reconstruction with placement of tissue expanders or immediate implant reconstruction, a surgical site infection involving the implant can result in its removal and a failed reconstruction.

The primary aim of the study is to determine if chlorhexidine disk application and irrigation of the drainage bulb with dilute Dakin's solution (buffered sodium hypochlorite solution)after tissue expander breast reconstruction or immediate implant reconstruction, effectively decreases rates of bacterial colonization in drain fluid compared to standard care.

Methods:

Patients undergoing bilateral immediate reconstruction with tissue expander placement will have one surgical site treated with standard drain care and the other treated with a drain antisepsis regimen. Drain antisepsis intervention will consist of two measures: 1) placement of a chlorhexidine sponge dressing at the drain exit site, and 2) twice daily irrigation of the drainage bulb with dilute Dakin's solution (buffered hypochlorite).

All patients will undergo semiquantitative cultures of the drain bulb at one week postoperatively. This culture will be repeated at the time of drain removal, with simultaneous cultures of the fluid in the bulb as well as an internal segment of each removed drainage tube. All patients will be evaluated for clinical signs of infection and for any adverse reactions to the drain antisepsis at the follow-up visits.
