The Effect of Photobiomodulation on Pressure Ulcers

Photobiomodulation Group (Intervention Group): Before the intervention, the patient's skin sensitivity to light will be tested by applying light for 3 minutes to one-fourth of the forearm skin. If redness occurs and persists for more than 2 hours, this indicates photosensitivity, and the intervention will not be performed. The Patient Information Form will be completed during the first meeting with the patients included in the study. Subsequently, blood values will be determined, the Patient Assessment Form will be filled out, vital signs will be measured, and then the intervention will begin. After routine wound care/cleaning procedures in the intensive care unit, without applying any medication, cream, or lotion to the wound area, red light (660 nm wavelength) will be applied to the wound area for 5 minutes at a distance of 55 cm during the first 3 days, and for 10 minutes at the same distance on the following days. This application will continue once daily for 14 days. Wound assessments will be performed, and photographs will be taken on Day 1, Day 4, Day 7, and Day 14 (Baracho et al., 2021; Viecelli et al., 2024; Lima et al., 2020). Control Group: The Patient Information Form will be completed during the first meeting with the patients included in the study. Subsequently, blood values will be determined, the Patient Assessment Form will be filled out, and vital signs will be measured. No intervention will be performed other than the routine wound care procedure carried out in the intensive care unit. Wound assessments will be performed, and photographs will be taken on Day 1, Day 4, Day 7, and Day 14, in the same manner as in the intervention group.
