NCT01126359

Brief Summary

The purpose of this prospective study is to compare pain levels and pain medication dose requirements in patients with topical negative pressure (TNP) dressings removed in a standard manner (i.v. or p.o. pain meds) compared to dressings removed with lidocaine analgesia, via injection 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 or medication requirements when patients receive a saline, control injection and pain medications, compared to when their dressings are changed with a lidocaine injection into the sponge, with pain medications. Our objective is to disprove this null hypothesis with statistical significance.

Outcome Measures

Primary Outcomes (1)

  • Visual Analog Scale Pain Score

    Visial Analog Pain Scores (VAS) range from 0 (no pain) - 10 (worst pain ever). Visial Analog Pain Scores are determined at each pain measurement time point (during/after VAC dressing removal).

    20 minutes

Secondary Outcomes (1)

  • Break-through Narcotic Requirement

    20 minutes

Study Arms (2)

Interventions

Interventional dressing change: iv or po pain medication with injection of 1% lidocaine retrograde up the suction tube into the sponge.

Limitations and Caveats

Overall subjectivity of pain and dosing of narcotic medications, all male cohort, timing of wound VAC changes, did not define the ideal lidocaine dosing for VAC changes or dosing method.
