  Purpose

The purpose of this prospective study is to compare pain levels in patients with topical negative pressure (TNP) dressings removed in a standard manner (i.v. or p.o. pain meds) compared to dressings removed after normal saline or lidocaine is injected retrograde up the suction tube into the foam prior to removal. Our null hypothesis is that there will be no difference in overall pain scores between the groups receiving saline injection and pain medications or just pain medications, compared to those with lidocaine injection and pain medications. Our objective is to disprove this null hypothesis with statistical significance.
