Topical Tranexamic Acid on Donor Wounds in Burn Patients: A Randomized Placebo-controlled Trial.

Background: Patients with major burn injuries are prone to massive blood loss owing to tangential excision of burn wounds and donor skin harvesting. In general, topical application of the antifibrinolytic drug tranexamic acid (TXA) to surgical wounds reduces bleeding; however, its effect on bleeding and re-epithelialization in superficial wounds of burns has not been explored.

Methods: This study aimed to investigate the therapeutic potential of topical TXA in reducing blood loss and its effect on wound re-epithelialization in burn surgery.

A new high-efficiency earmould.

The problems associated with earmoulds currently used by hearing-impaired persons, particularly children, are outlined. A new type of earmould which combines high efficiency with minimal feedback is described and evaluated.
