: Anaerobic bacteria like can lead to severe and life-threatening infections. The inherent complexities in the isolation of these bacteria may result in diagnostic and therapeutic delays, thereby escalating both morbidity and mortality rates. We aimed to examine data from patients with infections due to to gain insights into the epidemiology and clinical outcomes of patients with these infections.

Does frailty impact failure-to-rescue in geriatric trauma patients?

Background: Failure-to-rescue (FTR), defined as death following a major complication, is a metric of trauma quality. The impact of patient frailty on FTR has not been fully investigated, especially in geriatric trauma patients. This study hypothesized that frailty increased the risk of FTR in geriatric patients with severe injury.

Predictors of thrombosis during VV ECMO: an analysis of 9809 patients from the ELSO registry.

Venovenous extracorporeal membrane oxygenation (VV-ECMO) is a life-saving therapy for critically ill patients, but it carries an increased risk of thrombosis due to blood interacting with non-physiological surfaces. While the relationship between clinical variables and thrombosis remains unclear, our study aimed to identify which factors are most predictive of thrombosis. The Extracorporeal Life Support Organization Registry was queried to obtain a cohort of VV-ECMO patients aged 18 years and older from 2015 to 2019.

Comparison of bleeding and thrombotic outcomes in veno-venous extracorporeal membrane oxygenation: Heparin versus bivalirudin.

Methods: We performed a retrospective cohort study of adult patients placed on V-V ECMO with intravenous anticoagulation with either heparin or bivalirudin. Time to thrombotic event and major bleed were analyzed in addition to related outcomes.

Balloon Rises Above: REBOA at Zone 1 May Be Superior to Resuscitative Thoracotomy.

Background: The use of Zone 1 REBOA for life-threatening trauma has increased dramatically.

Study Design: The Aortic Occlusion for Resuscitation in Trauma and Acute Care Surgery database was queried for blunt and penetrating trauma between 2013 and 2021. Outcomes were examined both for mechanisms of injury combined and separately and for combinations of abdominal injury with and without traumatic brain injury and chest injuries (Abbreviated Injury Scale [AIS] score >2).

Expert consensus on training and accreditation for extracorporeal cardiopulmonary resuscitation an international, multidisciplinary modified Delphi Study.

Background: A multidisciplinary group of stakeholders were used to identify: (1) the core competencies of a training program required to perform in-hospital ECPR initiation (2) additional competencies required to perform pre-hospital ECPR initiation and; (3) the optimal training method and maintenance protocol for delivering an ECPR program.

Methods: A modified Delphi process was undertaken utilising two web based survey rounds and one virtual meeting. Experts rated the importance of different aspects of ECPR training, competency and governance on a 9-point Likert scale.

Use of Tranexamic Acid With Resuscitative Endovascular Balloon Occlusion of the Aorta is Associated With Higher Distal Embolism Rates: Results From the American Association of Surgery for Trauma Aortic Occlusion and Resuscitation for Trauma and Acute Care Surgery Trial.

Introduction: Tranexamic acid (TXA) use has been associated with thrombotic complications.

Objective: We aim to investigate outcomes associated with TXA use in the setting of high- (HP) and low-profile (LP) introducer sheaths for resuscitative endovascular balloon occlusion of the aorta (REBOA).

Participants: The Aortic Occlusion and Resuscitation for Trauma and Acute Care Surgery (AORTA) database was queried for patients who underwent REBOA using a low-profile 7 French (LP) or high-profile, 11-14 French (HP) introducer sheaths between 2013 and 2022.

Optimal positive end-expiratory pressure reduces right ventricular dysfunction in COVID-19 patients on venovenous extracorporeal membrane oxygenation: A retrospective single-center study.

While mechanical ventilation practices on venovenous extracorporeal membrane oxygenation (VV ECMO) are variable, most institutions utilize a lung rest strategy utilizing relatively low positive end-expiratory pressure (PEEP). The effect of PEEP titration using esophageal manometry during VV ECMO on pulmonary and cardiac function is unknown. This was a retrospective study of 69 patients initiated on VV ECMO between March 2020 through November 2021.

Evaluating Predictive Value of Surgical Resected Proximal Bone Margins in Diabetic Foot Osteomyelitis With Clinical Outcomes at 1 Year.

Background: Osteomyelitis of the diabetic foot remains a significant complication that may result in the need for amputation. Proximal surgical margin histopathology after limb-sparing amputation could be used to guide antimicrobial duration and prognostic management but remains debatable. Here we evaluate if negative proximal bone margins predict outcomes of diabetic foot osteomyelitis at 1 year.

Intimate Partner Violence and Pregnancy: Nationwide Analysis of Injury Patterns and Risk Factors.

Background: Intimate partner violence (IPV) is a significant cause of injury, and in pregnant patients (PIPV) poses a risk to both mother and fetus. Characteristics and outcomes for PIPV patients have not been well described. We hypothesize that PIPV patients have higher admission rates and mortality than non-IPV pregnant trauma (PT) patients and nonpregnant female IPV patients of childbearing age.

Case volume and rate are associated with outcomes in geriatric trauma: A case for geriatric trauma centers?

Background: Increased morbidity and mortality in geriatric trauma patients are usually due to decreased physiologic reserve and increased comorbidities. It is unclear whether geriatric trauma case volume and rates correlate with survival. We hypothesized that geriatric patients would have increased survival when treated in high-case volume and rate trauma centers.

Objective: Development of a standardized online assessment tool to evaluate the effectiveness of didactic and simulation-based ECMO courses on participants' confidence, knowledge, and simulation-based skills; participant satisfaction; and course educational benefits.

Starting and Sustaining an Extracorporeal Membrane Oxygenation Program.

The use of extracorporeal membrane oxygenation (ECMO) is growing rapidly in all patient populations, especially adults for both acute lung or heart failure. ECMO is a complex, high risk, resource-intense, expensive modality that requires appropriate planning, training, and management for successful outcomes. This article provides an optimal approach and the basic framework for initiating a new ECMO program, which can be tailored to meet local needs.

Novel method for left ventricular unloading utilizing percutaneous pulmonary artery drainage in cardiorespiratory failure due to COVID-19 infection.

Left ventricular (LV) unloading is an important concept in patients undergoing peripheral venoarterial extracorporeal membrane oxygenation (VA-ECMO). We present a case of a 32-year-old male in acute cardiorespiratory collapse due to coronavirus disease (COVID-19) who underwent VA-ECMO cannulation in the setting of cardiogenic shock and acute respiratory distress syndrome. Due to inability to utilize percutaneous LV assist device (pLVAD) for LV unloading due to small end diastolic dimension, alternative strategies were explored.
