Study summary

Emergent abdominal surgeries have very high rate of wound contamination due to exposure to bacteria from GI tract. There are several different approaches to wound management in these patients including wet-to-dry dressing or application vacuum assisted device on the wound. The investigators propose using the vacuum assisted device with Dakin's solution on patients undergoing emergency surgery for hollow viscus perforation installed immediately at the end of operation and remained there for the first 3 postoperative days, followed by delayed primary closure on postoperative day 4. The investigators believe this technique can achieve earlier wound closure, decrease patient discomfort, improve cost savings, and potentially standardize and revolutionize the investigators management of heavily contaminated wounds.

What researchers measure

Primary outcomes

  1. Rate of Surgical Site Infection

    Surgical site infection is defined as the presence of localized inflammatory signs such as hyperthermia, erythema, tenderness, or purulent discharge that results in positive cultures, along with positive wound cultures. Surgical site can also be regarded as infected based on the individual discretion of the treating physician. Surgical sites with \>10\^5 colonization in swab will be considered contaminated.

    Time frame: 2 weeks

Secondary outcomes

  1. Wong-Baker Faces Pain Rating Scale

    The Wong-Baker Faces Pain Rating scale is used to grade pain related to the presence/manipulation of the device. The Wong-Baker scale range is from 0 (No Hurt) to 10 (Hurts Worst) with numbers increasing by 2 (0, 2, 4, 6, 8, 10) and associated face images showing increased pain and sadness. Higher scores indicate increased pain, a worse outcome.

    Time frame: 1 week
