Background: Peripheral intravenous (PIV) infiltration and extravasation are common complications of intravenous fluid administration. Here, we aim to investigate risk factors associated with major adverse events following PIV infiltration, which may help risk stratify those who require early surgical consultation.
Methods: Retrospectively, patients were identified who had a documented PIV infiltration or extravasation event at 3 academic hospitals between 2015 and 2022.
Musculoskeletal injuries are common in Cameroon. Negative pressure wound therapy (NPWT) can effectively manage complex wounds including open fractures, however high cost and unavailability prevent its widespread use. We sought to evaluate the feasibility and efficacy in Cameroon of a low-cost NPWT (LCNPWT) device built from an aquarium pump costing less than $100.

The model inputs include atomic force microscopy values and micro-computed tomography on the first-day post osteotomy, which, combined with detailed finite element modeling, enables scrutinizing mechanical and biological interactions in early bone healing and throughout the healing process. The model detailed mesenchymal stem cell migration patterns, which are essential for tissue transformation and vascularization during healing, indicating the vital role of blood supply in the healing process.
View Article and Find Full Text PDFObjectives: This study aimed to determine whether outpatient upper extremity fracture surgery was associated with increased postoperative emergency department (ED) visits and identify related risk factors.
Design: Retrospective cohort.
Setting: This multicenter study was conducted within a single academic institution, encompassing two Level 1, two Level 2, and one Level 3 trauma centers.
Article Synopsis
- The study examined trends in surgical treatment for upper extremity fractures from 2008 to 2021, focusing on both inpatient and outpatient procedures and identifying patient factors influencing outpatient surgery.
- Outpatient surgeries increased by an average of 31%, with the most significant growth in humerus and forearm fractures, while older patients and those with higher comorbidities were more likely to require inpatient care.
- The findings suggest a notable shift toward outpatient management, highlighting the need for healthcare providers to consider socioeconomic disparities when making surgical decisions to ensure equitable access to care.
