This single-center, prospective, randomized, double-blind, controlled pilot study conducted at San Antonio Military Medical Center will evaluate the effectiveness of topical voriconazole for pain relief at autogenous skin donor sites compared to a topical placebo application. The patients will act as their own control. All participants and investigators in the study will be blinded to the treatment arm utilized on each of the patient's donor sites (voriconazole versus placebo). Patients, who are scheduled for skin grafting and have met the inclusion criteria for this study, will be invited to enroll in the study. Only those patients who have been planned for skin graft sites that are approximately symmetrical in size will be allowed to enroll in the study. The donor site wounds will be studied using a paired design consisting of voriconazole or the placebo applied topically to same-patient matched donor sites. Patients will be queried via the pain assessment tool as to perceived pain at timed intervals. Dialysate samples will be collected via microdialysis probes at matching timed intervals in order to measure levels of oxidized linoleic acid metabolites shown in previous studies to be present in peripheral nerves.
