Background and Objective: Complications following cardiovascular surgery incision
are common in mediastinitis and wound dehiscence form, a 47% mortality rate
remaining. Low Level Laser Therapy (LLLT) has been employed mainly to its
effectiveness analgesic and anti-inflammatory actions, aiding the tissue repair process.
The aim of this study was to evaluate infrared LLLT onto surgical incision in patients
submitted to cardiovascular surgery. Materials and Methods: 40 patients were divided
in two groups: Placebo Group (G1) – conventional therapy + “Laser pointer” and Laser
Group (G2) - conventional therapy + Infrared Laser irradiation on surgical incision.
Diode Laser was employed, C.W. mode, around the surgical wound bed, on immediate
Post Operative (PO), 1st PO and 3rd PO with the following parameters: wavelength (λ):
830nm, P=35mW, E=0,75J. Results: G2 didn’t present any complication and 5% of
patients in G1 developed incision dehiscence and infection. On 7thPO, still a large
amount of G1 patients showed pain and unquestionable inflammatory signs surrounding
the surgical wound, when compared to G2. Besides, hospital stay in Laser Group was 2
times shorter than in Placebo Group (p-value=0.001). Conclusion: Infrared Laser
denoted to be safe and exceptionally valuable tools in preventing morbidities on post
