Eficácia da terapia a laser de tecido profundo na cicatrização de úlceras por pressão em paciente com tetraplegia: relato de caso

CONTEXT:  Pressure ulcers (PU) are the most common complication noted in bed-ridden patients. The purpose of this case report is to explore the efficacy of class IV near-infrared laser therapy in the treatment of large and severe pressure ulcers.  FINDINGS:  A 53-years-old male diagnosed with quadriplegia due to cervical spine tuberculosis at level C5-C6 was admitted to a hospital with an unstageable pressure ulcer over the sacrum and National Pressure Ulcer Advisory Panel Pressure stage 3 ulcers over the right trochanteric area for pressure injury. No associated comorbidities like diabetes mellitus and hypertension were present. The Lite Cure Gallium-Aluminum-Arsenide (GaAlAs) class IV near-infrared laser, non-contact, continuous beam emission (non-pulsing) at 980nm wavelength, was used. The dosage parameters used were: 7.5 - 10 watts power; dose range 7 J/cm2 - 9 J/cm2; sacral area (13×9) cm2 and trochanteric area (10×8) cm2; at varying energy densities; treatment time ranges between 8 to 15 minutes for each ulcer. Total 19 sessions over 6 weeks were given to treat pressure ulcers. Dimensions (area) and severity stage of pressure ulcer were noted pre-intervention and after the intervention. The post-treatment data revealed the clinical improvement in both outcomes.  CONCLUSION/CLINICAL SIGNIFICANCE : This case report demonstrates the anti-inflammatory, analgesic, and bio-stimulative healing effects of Class IV laser therapy treatment showing a reduction in the dimensions and severity of pressure ulcers.
