Experimental model for low level laser therapy on ischemic random skin flap in rats

Abstract: Purpose:To develop an experimental model to be used in the study of low level Laser therapy on viability of random skin flap in rats. Methods: The sample was 24 Wistar-EPM rats. The random skin flap measured 10 x 4 cm and a plastic sheet was interposed between the flap and donor site. Group 1 (control) underwent sham irradiation with diode laser (830 nm). Group 2 was submitted to laser irradiation with diode laser (830 nm). The animals were submitted to Laser therapy with 36 J/cm 2 energy density (72 seconds) … Show more

“…A eficácia da fototerapia na aceleração da reparação de feridas cutâneas é amplamente conhecida (Walker et al, 2000). A radiação eletromagnética, coerente e não-coerente, aumenta, significativamente, a neovascularização em tecido lesionado, acelerando o processo de reparo e diminuindo a área de necrose, indicando um aumento do fluxo sanguíneo em locais de lesão (Kubota, 2002;Prado et al, 2006;Schindl et al, 2002;Yu et al, 2006).…”

“…A área de lesão no grupo irradiado pode estar relacionada com maior celularidade (número de fibroblastos), observada na análise quantitativa. Segundo Kubota (2002), Prado et al (2006), Schindl et al (2002) e Yu et al (2006), a fototerapia pode aumentar significativamente a neovascularização e o fluxo sanguíneo em locais de lesão.…”

“…The studies found in the literature dealing with this topic used lasers operating at wavelengths of 632.8 5,7,9 , 660 19 and 830 nm 3,4,6,8 , and emitting continuous light (Table 3). In the present study, the increase in survival observed in irradiated skin flaps agrees with previous studies [19][20][21][22] , except for Smith, 9 who did not find any significant effect in the use of laser therapy.…”

“…Furthermore, the use of "energy delivered to the tissue" instead of "energy density" as a parameter for analysis may be necessary since many studies [3][4][5][6][7][8] show apparent contradictions in the results when the parameter energy density is evaluated. The World Association for Laser Therapy (WALT) 29 recommends on their website the use of energy dose delivered to the tissue as a dosimetric parameter in the treatment of pain.…”
