Preoperative Mild Pericardial Effusion Is Associated With Perioperative Complications In Elderly Patients Following Hip Fracture Surgery.

The prevalence and prognostic value of mild pericardial effusion (MPE) has not been examined in patients undergoing non-cardiac surgery. Our study aimed to assess the frequency and prognostic value of MPE in elderly patients undergoing surgery for hip fracture. This is a single center, and retrospective study including elderly patients who underwent hip fracture surgery. The medical records of all patients, aged ≥65 years with femoral neck, intertrochanteric or subtrochanteric hip fracture undergoing surgery (intramedullary hip screw, sliding compression hip screw, hemiarthroplasty, or total hip arthroplasty) from June 2014 to June 2019 were analyzed. Patients with of multiple trauma and accidents were excluded. The MPE was defined as the presence of <10 mm pericardial effusion. The primary outcomes of the study were perioperative adverse medical events and length of stay in hospital. A total of 462 patients (mean age 75.2 ± 11.7 years, and 53.5% female) were enrolled. MPE was detected in 72 patients (15.6%), and 62 patients (13.4%) experienced perioperative adverse medical events. Patients with MPE were older, had higher prevalence of diabetes, coronary artery disease, and heart failure, and had longer length of stay compared to patients without MPE. Univariate analysis showed a significant association between age, diabetes, coronary artery disease, American Society of Anesthesiologists status, MPE, and perioperative adverse events. After adjustment for age, demographics, and medical history, the presence of MPE remained as significant variable associated with perioperative complications (OR: 2.543, 95% CI: 1.173-3.469,  = 0.003). : Our study is the first to demonstrate that the presence of MPE is associated with perioperative adverse events in elderly patients undergoing hip fracture surgery.
