Effect of comprehensive nursing based on evidence-based nursing on reducing the incidence of pressure ulcers in patients undergoing posterior orthopedic surgery

To analyze the effect of comprehensive nursing based on evidence-based nursing during the perioperative period on reducing the incidence of pressure ulcers in patients undergoing posterior orthopedic surgery. Data on 120 patients who underwent orthopedic posterior surgery in our hospital from February 2021 to December 2022 were retrospectively analyzed. The patients were divided into an observation group (n = 60) and a control group (n = 60) based on different nursing methods. Patients in the control group received routine nursing, whereas those in the observation group received comprehensive nursing under the guidance of the concept of evidence-based nursing. The incidence of postoperative pressure ulcer was also recorded. Fasting venous blood (5 mL) was collected from patients before and after surgery and used to measure levels of myeloperoxidase (MPO) and superoxide dismutase (SOD) using enzyme-linked immunosorbent assay. Ulcer tissue samples of patients with pressure ulcers were collected and used to detect the expression of caspase-3 protein, vascular endothelial growth factor (VEGF) mRNA, tumor necrosis factor-α (TNF-α) mRNA, and interleukin-1β (IL-1β) mRNA. The incidence of postoperative pressure ulcers was 8% in the observation group and 23% in the control group (P = .024). The scores of sensory perceptions of the patients in the observation group were significantly lower than those in the control group (P < .001), as were the scores for moisture (P < .001), activity (P = .008), mobility (P < .001), nutrition (P = .003), friction, and shear (P < .001). After surgery, the serum MPO level in the observation group was significantly lower than that in the control group (P < .001), whereas the SOD level in the observation group was significantly higher than that in the control group (P < .001). The expression of TNF-α, IL-1β, VEGF mRNA, and caspase-3 protein in pressure ulcer tissues in the observation group was significantly lower than that in the control group. Comprehensive nursing based on the concept of evidence-based nursing can significantly reduce the incidence of postoperative pressure ulcers following posterior orthopedic surgery.
