Instilled Lidocaine vs Placebo for Pain Management During Vacuum Assisted Closure (VAC) Dressing Changes.

• All Burn service patients (inpatients and outpatients in burn clinic) who are receiving VAC therapy will be screened for study inclusion criteria. Those with allergies to lidocaine will be excluded. Participants will be enrolled until a sample size of 80 wound VAC changes is achieved. Up to 4 VAC dressing changes can be included in this study per participant. Subjects will be randomized prospectively for each dressing change. Utilizing a randomized bracketed approach, patients will be assigned to one of two groups: Lidocaine group or Placebo group. The Pharmacy Research Center (PRC) will assign patient a study Identification (ID) number and record it along with their medical record number on the Master Study ID List. They will then randomize the participants by drawing randomly shuffled green vs white index cards. (40 white card = 0.9 normal saline and 40 green card = 5 mg/kg of 1% Lidocaine). They will draw up the appropriate amount of medication to be used, label it with the patients Medical Record (MR) #, date, and administration instructions and deliver it to the nurse who is doing the VAC dressing change. They will keep the Master Randomization Data Collection Tool in a locked drawer in her office.
