AI Article Synopsis
- The study investigates the relationship between intraoperative mean arterial pressure variability (MAPV) and postoperative delirium (POD) in elderly patients after hip fracture surgery.
- Out of 963 patients aged 65 and older, 11.9% experienced POD within a week post-surgery, with a significant association found between high MAPV and increased risk of POD.
- The findings suggest that higher MAPV (over 2.17) could serve as a predictor for POD, indicating that monitoring MAPV during surgery may help identify at-risk patients.
Article Abstract
Background: Postoperative delirium (POD) is a common complication in elderly patients after hip fracture surgery. Our study was to investigate whether intraoperative mean arterial pressure variability (MAPV) was associated with POD in elderly patients after hip fracture surgery.
Methods: In this retrospective cohort study, patients aged 65 years and older undergoing hip fracture surgery were included. The correlation between MAPV and POD was investigated using univariate and multivariate logistic regression. Covariate-related confounding effects were eliminated with propensity score matching (PSM) analysis. Then, a subgroup analysis was conducted to further examine the associations between MAPV and POD.
Results: Nine hundred sixty-three patients with a median age of 80 years (IQR: 73-84) were enrolled. POD occurred in 115/963 (11.9%) patients within 7 days after surgery. According to multivariate regression analysis, MAPV > 2.17 was associated with an increased risk of POD (OR: 2.379, 95% CI: 1.496-3.771, P < 0.001). All covariates between the two groups were well balanced after PSM adjustment. A significant correlation between MAPV and POD was found in the PSM analysis (OR: 2.851, 95% CI: 1.710-4.746, P < 0.001).
Conclusions: An increased intraoperative MAPV may be a predictor for POD.

Spinal Anesthesia in Elderly Patients With Femoral Neck Fractures on Apixaban Therapy: A Case Series.
A A Pract
January 2025
From the Department of Anesthesiology, Sheba Medical Center, Ramat Gan, Israel.
This case series reviews surgeries involving elderly patients with femoral neck fractures on apixaban who underwent spinal anesthesia (SA) within 72 hours of their last dose. Despite patients being on anticoagulation, no neurological complications occurred, suggesting SA may be practical in cases where the benefits of timely surgery outweigh the potential risks, including apixaban discontinuation for a period of less than the recommended 72 hours with detectable levels of the drug remaining in the plasma. Quantitative apixaban measurements offered useful anticoagulation status insights, though safe thresholds remain undefined.

Introduction: Hip fractures are common and are a major cause of significant morbidity and mortality in the elderly population, particularly when treatment is delayed. The British Orthopaedic Association's (BOA) guidelines state that surgical treatment should be performed within 36 hours of admission. This study aimed to investigate the effects of delays in surgery on clinical outcomes and to evaluate mortality rates over a three-year follow-up period following proximal femoral fractures.

Background: Despite multiple studies, less recent literature and data regarding the mortality associated with hip fractures in the elderly population are available.
Objectives: To assess the mortality data and functional outcomes of patients who underwent cemented and uncemented hemiarthroplasty in femoral neck fractures. To evaluate if preoperative (minimum 2 months) calcium and vitamin D supplement intake in patients affects postoperative mobilization with or without walker support.

Aims: The primary aim of this study is to compare mobility status of patients receiving oral oxycodone with those receiving subcutaneous alfentanil as analgesic methods prior to mobilization to help physiotherapy compliance after hip fracture surgery. The secondary aims are to assess postoperative pain, health-related quality of life, in-hospital length of stay, total use of analgesia over postoperative days 1 and 2 (POD 1 and POD 2), complication rates within 30 days, and 30-day mortality rates.
Methods: A single-centre, prospective cohort study of 64 patients will be undertaken.
