ABSTRACT
OBJETIVO: Analisar a dosimetria do laser de baixa intensidade no processo de cicatrização de úlcera venosa. MÉTODO: Trata-se de um protocolo de revisão sistemática registrado no International Prospective Register of Systematic Reviews (PROSPERO) sob código de registro CRD420211256286. Serão realizadas buscas por evidências científicas em 11 bases de dados, utilizando os idiomas português, inglês e espanhol. A exportação das publicações seguirá as etapas de identificação e seleção dos estudos, e extração dos dados. As divergências serão resolvidas por consenso dos dois revisores, e caso persistam, um terceiro revisor será consultado para decidir sobre a inclusão do material. A ferramenta Risk of Bias 2 (RoB 2) será utilizada para avaliar o risco de viés dos estudos dos ensaios clínicos randomizados, ao passo que a ferramenta Risk of Bias in Non-randomized Studies of Interventions (ROBINS-I) será utilizada para avaliar o risco de viés dos ensaios clínicos não randomizados. A análise crítica dos materiais selecionados quanto à dosimetria do laser de baixa intensidade para cicatrização de úlcera venosa resultará em uma síntese narrativa, sem metanálise.
OBJECTIVE: To analyze the dosimetry of low-level laser therapy in the healing process of venous ulcers. METHOD: This is a protocol for systematic review registered in the International Prospective Register of Systematic Reviews under registry code CRD420211256286. Articles will be searched in 11 databases using Portuguese, English, and Spanish languages. The export of publications will follow the steps of study identification, selection, and data extraction. Disagreements will be resolved by consensus among reviewers; if they persist, a third reviewer will be consulted to decide whether to include the material. The Risk of Bias 2 (RoB 2) tool will be used to assess the validity of randomized clinical trials, while the Risk of Bias in Non-randomized Studies of Interventions (ROBINS-I) tool will be used to assess the risk of bias in non-randomized clinical trials. The critical analysis of selected materials on dosimetry of low-level laser therapy for venous ulcer healing will result in a narrative synthesis without meta-analysis.

BACKGROUND: Different methods are available for the treatment of venous ulcers. Most current approaches focus on a combination of topical and compressive therapy. Adjuvant low-level laser therapy may be helpful in lesions with a protracted healing course, but evidence for its use is still limited. This paper describes the protocol of a randomized controlled trial designed to compare the effect of adjuvant low-level laser therapy versus conventional venous ulcer tissue repair, evaluated by a nurse using clinical indicators from the Nursing Outcomes Classification (NOC). METHODS/DESIGN: For this prospective randomized controlled trial, 40 adult patients of both sexes with active venous ulcers will be recruited. Subjects will be selected by the sealed-envelope method without any annotation or external identification that might refer to the type of study group. At the time of unblinding, a label with the description of the group to which the patient belongs (that is, control or intervention) will be found inside the envelope. Conventional treatment (topical medication and compressive therapy) will be offered to both groups. Additionally, the intervention group will receive adjuvant low-level laser therapy. All patients will be followed weekly until ulcer healing or for a maximum of 16 weeks. Evaluation of tissue repair will be based on 14 clinical indicators drawn from NOC for wound healing (secondary intention) and tissue integrity (skin and mucous membranes). The primary endpoint will be decreased wound size and scar formation. This laser therapy is expected to enhance the quality, speed, and effectiveness of the treatment of venous ulcers, a chronic condition. This should reduce associated costs to the health service and allow patients to resume their daily activities sooner. DISCUSSION: This randomized clinical trial will use a validated method to investigate the effect of a novel intervention for the treatment of venous ulcers. TRIAL REGISTRATION: ClinicalTrials.gov, NCT03229330 . Registered on July 2017.

Se exponen los resultados obtenidos con el empleo de la laserpuntura a un total de 21 casos remitidos por el Servicio de Angiología con el diagnóstico de úlceras de tipo flebotónicas y postraumáticas al Hospital General "Ciro Redondo"de Artemisa. La información sobre los pacientes se registró en un documento confeccionado al efecto. En la investigación se usó un modelo de grupo único, lineal, y se les aplicó a las tablas el cálculo de X2, así como el valor promedio. Los resultados que se obtuvieron fueron de 95,2 por ciento de mejoría y cura de las lesiones y el 90 por ciento de confianza en afirmar que las úlceras de causa traumática evolucionan de manera favorable y más rápida que las de causa venosa, y reafirman la ventaja de esta modalidad de tratamiento(AU)
The results obtained using laser-puncture in a total of 21 cases referred to the Angiology Service of "Ciro Redondo" General Hospital, in Artemisa province, are shown. Information on patients was registered in a document designed for that purpose. In research, we used a form of linear unique group and the X2 estimate and the average value were applied to the tables. It was obtained 95.2 percent of improvement and cure of lesions and 90 percent of confidence on guaranteeing that the ulcers of traumatic origin evolve in a favorable way and more quickly than those of venous origin, which reaffirms the advantages of this treatment modality(AU)
