Study summary

Abscesses or "boils" are becoming more common every year and are a common reason children come to the Emergency Department. For the abscess to heal the skin needs to be opened to let the pus come out. Often doctors put something called "packing material" or gauze into the abscess space to help aid in healing. It is not known if the type of "packing" that is done is necessary or if a more simple treatment is as good or better. With informed consent we randomly place a child into one (1) of two (2) groups in this study that will say if the child's abscess/boil is packed with gauze in the traditional way or if a wick (small piece) of gauze is placed after the abscess/boil is opened and the fluid is drained. After treatment in the emergency department the child will be scheduled to follow-up in the Pediatric Acute Wound Service (PAWS) clinic as all other children with this infection are scheduled. At this visit the healing of the wound will be checked by the staff in the clinic and will be scored. With this evaluation of the wound the hypothesis that for a simple superficial (skin) abscess/boil a gauze wick placement into the abscess/boil is as effective as placement of traditional gauze packing.

What researchers measure

Primary outcomes

  1. Abscess healing based upon clinical criteria and clinical judgement

    Abscesses are assessed for pus accumulation, erythema from the wound, if the patient has a fever and the overall clinical judgment of the evaluating health care professional at the time of follow-up.

    Time frame: 24-72 hours

Secondary outcomes

  1. Pain since abscess drainage

    Time frame: 24-72 hours

  2. Parent/guardian comfort with removing the packing material or wick from the abscess cavity

    Time frame: 24-72 hours

  3. Parent/guardian assessment of the abscess wound at 2 weeks

    Time frame: 2 weeks

  4. Parent/guardian assessment of pus drainage at 2 weeks

    Time frame: 2 weeks

  5. Need for further treatment of same abscess within 2 weeks

    Time frame: 2 weeks
