Abstract

BACKGROUND
For reducing intraoperative bleeding, epinephrine is commonly used as a vasoconstrictor with infiltration anesthesia. However, the effects of epinephrine on postoperative bleeding complications are still a matter of debate. Bleeding is a potential complication of negative-pressure wound therapy (NPWT), which is widely used in the post-debridement management of pressure ulcers. We hypothesized that the risk of post-debridement bleeding would be greater if negative pressure were applied postoperatively to pressure ulcers while bleeding conditions were masked by the vasoconstrictive effect of epinephrine.
METHODS
A 3-year retrospective chart review of 38 patients who received 204 surgical debridement and NPWT procedures was performed to evaluate the incidence of bleeding complications by type of local infiltration (i.e., no infiltration, lidocaine infiltration only, or infiltration of lidocaine mixed with epinephrine).
RESULTS
A total of 18 postoperative bleeding complications were observed, eight from the non-injection group and five from each of the lidocaine and lidocaine-epinephrine injection groups. Procedures with epinephrine infiltration had a 31.9% higher rate of bleeding complications than others, but the difference was without statistical significance.
CONCLUSION
The use of epinephrine for infiltration led to a higher risk of bleeding complications when NPWT was applied after pressure sore debridement, but this trend did not reach statistical significance. A more detailed and extensive future study would help obtain more conclusive results.
