Abstract:Objective To study the risk factors of pulmonary infection after elderly hip fracture surgery and the predictive value of immune inflammatory factors on infection. Methods 283 patients with hip fracture surgery in the hospital from January 2020 to December 2021 were selected as samples to conduct a retrospective study. The medical records of patients were sorted out and the related data were collected in detail, and the patients were divided into infection group and control group according to whether pulmonary infection occurred within 28 days after surgery. The various indicators were compared between the two groups and the risk factors of pulmonary infection were analyzed, and then the predictive value of immune inflammatory factors on pulmonary infection and relationship with infection degree were discussed. Results Among 283 elderly patients with hip fractures, 46 cases (16.25%) developed pulmonary infection after surgery. Age, number of complications≥3, time from fracture to hospital admission, intensive care unit (ICU) admission and systemic immune inflammation index (SII) were independent risk factors of postoperative pulmonary infection in elderly patients with hip fractures (P<0.05). Neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and SII all had certain reference value on predicting pulmonary infection (P<0.05). NLR, PLR and SII showed increasing trends with the increase of pulmonary infection degree, and the differences between both groups were statistically significant (P<0.05). The NLR, PLR and SII were significantly positively correlated with PCIS score in elderly patients with hip fractures and postoperative pulmonary infection (r=0.372, 0.633, 0.574, P<0.05). Conclusion The risk factors of postoperative pulmonary infection in elderly patients with hip fractures include age, number of complications≥3, time from fracture to hospital admission, ICU admission and SII. The detection of NLR, PLR and SII can provide reference for determining the risk and severity of pulmonary infection.
