Primary Outcome Measures:
  • Infection rate in colorectal surgeries in each of two treatment arms as compared to historic controls [ Time Frame: 30 days after surgery ] [ Designated as safety issue: No ]
    pilot study to evaluate 1. pressurized irrigation of the superficial surgical wound after fascial closure in 40 patients and 2. subcutaneous gentamicin into the surgical area prior to initial incision in 40 patients and compare rates of surgical site infections after 30 days to historic controls.

Estimated Enrollment: 120
Study Start Date: August 2010
Estimated Study Completion Date: December 2012
Estimated Primary Completion Date: September 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Pressurized irrigation
first group-After closure of patients abdominal wall fascia, Hydrostatic irrigation with 3 liters of normal saline with Simpulse Solo irrigation system (Davol) at less than 15PSI will be applied to subcutaneous tissues prior to closure
Procedure: Normal saline pressurized irrigation
Other Name: 1st group
Experimental: Sub Q Antibiotic
second group of patients will receive 2mg/lg of gentamicin in 20 ml of sterile saline injected into the superficial tissues above the ABD wall fascia prior to initial incision
Drug: sub-q gentamicin
2mg/kg of gentamicin in 20 ml of sterile saline up to max dose of 120mg injected above the abdominal wall fascia- the length of the incision will be marked and injection made with intent being to evenly distribute the volume of injection in the subcutaneous tissues in immediate vicinity of and prior to the initial incision- analogous to the technique employed when using local anesthetic
Other Name: 2nd group

Detailed Description:

The population for inclusion for this study will be drawn from the patients undergoing elective transabdominal colorectal surgery. This population was chosen due to its inherently high rate of superficial-incisional infection.Colorectal procedures stand out as a particularly highrisk surgery with respect to SSI. Several studies have reported rates of infection of 25% or more making colorectal surgeries an excellent opportunity for testing new strategies to reduce SSI.

This pilot project seeks to preliminarily evaluate two new strategies that are inexpensive and could be readily incorporated into current practice. The strategies are pressurized irrigation of the superficial surgical wound (above the fascia) and subcutaneous injection of gentamicin into the surgical wound prior to initial skin incision. Comparison will be made between prospectively enrolled patients and historic controls.The hypothesis to be tested is that these interventions will significantly reduce superficial incisional infection rates compared with historic control.


Ages Eligible for Study:   18 Years to 95 Years

  • willing and capable of giving self informed consent

Exclusion Criteria:

  • patients unable to give informed consent
  • emergency colorectal procedures
  • transanal procedures
  • patients who have contaminated or dirty wounds that would preclude attempts at skin closure at the conclusion of the procedure
  • patients undergoing appendectomy

  • patients with pre/op creatinine clearance less than 20ml/min
  • patients with known allergy or hypersensitivity to gentamicin
  • patients that have received gentamicin within 2 weeks of potential study date
