Research Article: The prevalence and risk factors of acute kidney injury in post-orthopedic surgery patients
Abstract:
This study aimed to investigate the prevalence and identify the risk factors associated with acute kidney injury (AKI) in patients undergoing orthopedic surgery.
A retrospective study was conducted on 2,796 patients admitted to the orthopedic ward for bone tumors, bone injuries, and spinal diseases between 2017 and 2020. Patients were categorized into non-AKI, AKI stage 1–2, and AKI stage 3 groups. Data were analyzed using chi-square, Fisher’s exact, Kruskal-Wallis tests, and logistic regression to compare groups and determine independent risk factors for AKI.
AKI occurred in 97 patients, yielding an overall prevalence of 3.47%. The incidence was highest among patients undergoing bone tumor surgery (11.36%) and lowest in those undergoing spinal surgery (2.46%). Patients in the AKI stage 3 group had a significantly higher proportion of bone tumor surgeries and longer hospital stays compared to other groups ( P < 0.001). Multivariate analysis identified bone tumor surgery, preoperative proteinuria, elevated urea, decreased hemoglobin, and the use of proton pump inhibitors (PPIs) and non-steroidal anti-inflammatory drugs (NSAIDs) as independent risk factors for AKI.
There is a significant risk of AKI following orthopedic surgery, particularly in patients undergoing bone tumor procedures. The study underscores several key modifiable risk factors, including the use of PPIs and NSAIDs, as well as preoperative conditions like proteinuria, anemia, and elevated urea.
Introduction:
Acute kidney injury is a common clinical complication characterized by a rapid decline in renal function in a short period of time. It is closely associated with high mortality, poor prognosis, and a variety of serious complications ( 1 ). In recent years, the prevalence of AKI has been increasing, posing a significant public health challenge. This trend is particularly concerning in perioperative patients, where AKI occurrence leads to prolonged hospital stays, increased medical costs, and a heightened risk of…
