Abstract: Introduction: Acute respiratory infection (ARI) can significantly reduce postoperative quality of life and impair the recovery of older adult patients with lower-limb fractures, and its relationship with methods of anesthesia remains inconclusive. Using data from the National Health Insurance Research Database (NHIRD) of Taiwan, this study examined the data of patients who received surgical management for lower-limb fractures and compared those who underwent general anesthesia (GA) with those who underwent regional anesthesia (RA) in terms of their incidence of acute upper and lower respiratory infection during the one-month postoperative period. The study also identified related risk factors. Material and Methods: Approximately two million patients were randomly sampled from the NHIRD registry. We identified and enrolled patients with lower-limb fractures who were over 60 years old and underwent GA or RA during surgeries conducted between 2010 and 2017. We divided these patients into two groups for further analysis. The outcome of this study was the development of ARI during the one-month postoperative period. Results: In total, 45,032 patients (GA group, 19,580 patients; RA group, 25,452 patients) with a mean age of 75.0 ± 8.9 years were included in our study. The incidence of postoperative ARI within one month of surgery was 8.0% (1562 patients) in the GA group and 9.5% (2412 patients) in the RA group, revealing a significant difference. The significant risk factors for the incidence of ARI were the application of RA for surgery, older age, hypertension, liver disease, and chronic obstructive pulmonary disease (COPD). A subgroup analysis revealed that the RA method was associated with a significantly higher ARI incidence relative to the GA method among patients aged between 60 and 80 years, among male patients, among the patients with or without any comorbidity and among the patients without COPD. Conclusion: The incidence of postoperative ARI within one month of surgery was higher among older patients with lower-limb fractures who received RA for surgery than among those who received GA for surgery. The other major risk factors for ARI were older age, hypertension, liver disease, and COPD. Therefore, we should focus on patients with a high risk of developing ARI, especially during the COVID-19 pandemic.
