Perioperative Factors Associated with Delayed Graft Function in Adults Undergoing Deceased Donor Kidney Transplantation

Introduction: In adult patients undergoing deceased donor kidney transplantation, anesthesia management impacts graft function and survival and is influenced by various donor and recipient clinical factors. The aim of this study was to describe the perioperative factors and to evaluate their association with delayed graft function (DGF) during the first seven days after transplantation. Materials and Methods: This cross-sectional study of adult patients who underwent deceased donor kidney transplantation at a tertiary care hospital from 2022–2023 was performed to evaluate pre-, trans- and postoperative patient’s characteristics. Comparisons or association tests were implemented between patient characteristics grouped by the absence or presence of DGF. In the case of the variables with clinical relevance, univariate and multivariate logistic models were constructed to evaluate the predictive capacity of these variables to predict delayed graft function. Crude and adjusted odds ratio (ORs) with 95% confidence intervals were calculated for each variable. Results: DGF was present in 25/69 (36.23%) patients. The anesthesia time was significantly longer (310.28 vs. 273.55 min; p = 0.043) and the post-transplantation stay was significantly longer (11.04 vs. 8.11 days; p < 0.001) in patients with delayed graft function. In univariable analyses, male sex (p = 0.018), platelet count (p = 0.025), and surgical time (p = 0.062) showed significant or borderline associations with DGF. In the multivariable model, male sex remained independently associated with DGF (adjusted OR 10.64; 95% CI 1.23–92.1; p = 0.031). Platelet count (per 50 × 103 µL increase) demonstrated a borderline inverse association (adjusted OR 0.57; 95% CI 0.32–1.02; p = 0.057). Conclusions: Our results suggest that male sex was independently associated with delayed graft function after deceased donor kidney transplantation, while platelet count showed a borderline association.
