Nosocomial wound infection with (PA) is a serious complication often responsible for septic mortality of burn patients. High-intensity antimicrobial blue light (aBL) treatment may represent an alternative therapy for PA infections. Antibacterial effects of an light-emitting diode (LED) array (450-460 nm; 300 mW/cm; 15/30 min; 270/540J/cm) against PA were determined by suspension assay, biofilm assay, and a human skin wound model and compared with 15-min topically applied 3% citric acid (CA) and wound irrigation solution (Prontosan; PRT).

Background: Although high-energy trauma mechanisms are generally considered to cause traumatic posterior hip dislocations, femoroacetabular variations are assumed to contribute to low-impact hip dislocations. Thus, the present study aimed to identify morphologic femoral and acetabular risk factors that may also contribute to posterior hip dislocations in high-energy trauma mechanisms.

Methods: The acetabular and femoral morphology of 83 hips with a traumatic posterior dislocation following a high-energy trauma mechanism were analyzed and matched to a control group of 83 patients who sustained high-energy trauma without a hip injury.

Burn surgery on the hands is a difficult procedure due to the complex anatomy and fragility of the area. Enzymatic debridement has been shown to effectively remove burn eschar while minimizing damage to the surrounding tissue and has therefore become a standard procedure in many burn centers worldwide over the past decade. However, surprisingly, our recent literature review showed limited valid data on the long-term scarring after the enzymatic debridement of the hands.

Introduction: Fluid resuscitation has long been a cornerstone of pre-hospital trauma care, yet its optimal approach remains undetermined. Although a liberal approach to fluid resuscitation has been linked with increased complications, the potential survival benefits of a restrictive approach in blunt trauma patients have not been definitively established. Consequently, equipoise persists regarding the optimal fluid resuscitation strategy in this population.

Update on the pathophysiology and management of acute trauma hemorrhage and trauma-induced coagulopathy based upon viscoelastic testing.

Clin Exp Emerg Med

September 2024

Department of Trauma and Orthopedic Surgery, Cologne-Merheim Medical Center (CMMC), Witten/Herdecke University, Cologne, Germany.

Uncontrolled hemorrhage and trauma-induced coagulopathy (TIC) are the two predominant causes of preventable death after trauma. Early control of bleeding sources and rapid detection, characterization and management of TIC have been associated with improved outcomes. However, recent surveys confirm vast heterogeneity in the clinical diagnosis and management of hemorrhage and TIC from acute trauma, even in advanced trauma centers.

The accurate positioning of the femoral tunnel is crucial for the success of anterior cruciate ligament reconstruction. Malpositioning of the tunnel is believed to be one of the most important reasons for graft failure. While use of anatomic landmarks and industry-supplied aiming devices aid the surgeon in placing the drill pin in the correct position, fluoroscopic imaging is an additional tool used intraoperatively to verify pin placement.

Management of patients with proximal femur fractures under DOACs.

Eur J Trauma Emerg Surg

April 2024

Department for Trauma and Orthopedic Surgery, Cologne-Merheim Medical Center (CMMC), Witten/Herdecke University, Campus Cologne-Merheim, Ostmerheimer Str. 200, 51109, Cologne, Germany.

Purpose: In the past, preinjury direct oral anticoagulant (DOAC) intake has led to delays in time to surgery (TTS) in patients with proximal femur fractures and delays in surgery have been associated with impaired outcomes. Although healthcare institutions/federal committees have set rules for treatment within 24 h of injury, comprehensive guidelines for the perioperative management of these patients, in particular when on preinjury DOACs, are still lacking. This contribution aims to summarize the current evidence on the safe time window for surgery in patients with proximal femur fractures on preinjury DOACs and to outline therapeutic options if emergency DOAC reversal becomes necessary.

Purpose Of Review: The diagnosis and treatment of patients with severe traumatic bleeding and subsequent trauma-induced coagulopathy (TIC) is still inconsistent, although the implementation of standardized algorithms/treatment pathways was repeatedly linked to improved outcome. Various evidence-based guidelines for these patients now exist, three of which have recently been updated.

Recent Findings: A synopsis of the three recently updated guidelines for diagnosis and treatment of seriously bleeding trauma patients with TIC is presented: (i) AWMF S3 guideline 'Polytrauma/Seriously Injured Patient Treatment' under the auspices of the German Society for Trauma Surgery; (ii) guideline of the European Society of Anesthesiology and Intensive Care (ESAIC) on the management of perioperative bleeding; and (iii) European guideline on the management of major bleeding and coagulopathy after trauma in its 6th edition (EU-Trauma).

Article Synopsis
  • Doctors have gotten better at taking care of injured patients both before they reach the hospital and in the emergency room, which helps them live longer.
  • However, many people still die from bleeding because there aren't enough treatments specifically for it.
  • There are also big gaps in understanding how injuries affect the body’s response, so researchers are looking for new ways to improve treatments for trauma in the future.
