Avaliação dos resultados da aplicação do ultrassom terapêutico em diferentes intensidades na cicatrização tecidual de cães submetidos à orquiectomia

Abstract

The use of alternative techniques that stimulate wound healing has been studied in several areas of biologic sciences. Wounds are solutions of continuity characterized by the loss of tissue integrity and can be classified in several types including surgical wounds. Therapeutic ultrasound (Therapeutic US) is a largely used technique in skeletal muscle system disorders for its pro-inflammatory and analgesic effects. It has been suggested that therapeutic US is also beneficial in the tissue healing stimulation. The present study aimed to evaluate the effects of therapeutic ultrasound on the tissue healing of dogs submitted to orchiectomy at the Hospital Universitário de Medicina Veterinária of UFRB (HUMV-UFRB). 24 animals were randomly divided in 3 groups of 8 animals each where the control group did not receive the therapeutic US, the group 1 received the therapeutic US in a 3MHz frequency and the group 2 received the therapeutic US in a 1MHz frequency. The evolution of the wound was evaluated over a period of 10 days through parameters such as macroscopic effects, tissue contraction rate and pain index. No relevant results were observed using therapeutic ultrasound to accelerate inflammation or for pain control. However, it can be stated that there was a higher rate of tissue contraction in group 1, which received treatment withtherapeutic US in the frequency of 3 MHz.
