Hepatic artery pseudoaneurysm rupture: A case report.

Hepatic artery pseudoaneurysms are an uncommon complication of blunt hepatic trauma typically presenting in a delayed fashion. A 40-year-old male presented to a trauma centre after a 6-metre fall from a construction site with multiple injuries including a grade IV liver laceration centred around the porta hepatis. This liver injury was managed non-operatively.

Risk factors for breast cancer-related lymphedema in patients undergoing 3 years of prospective surveillance with intervention.

Background: To evaluate risk factors (treatment-related, comorbidities, and lifestyle) for breast cancer-related lymphedema (BCRL) within the context of a Prospective Surveillance and Early Intervention (PSEI) model of care for subclinical BCRL.

Methods: The parent randomized clinical trial assigned patients newly diagnosed with breast cancer to PSEI with either bioimpedance spectroscopy (BIS) or tape measurement (TM). Surgical, systemic and radiation treatments, comorbidities, and lifestyle factors were recorded.

Blunt thoracic aortic injury resulting in free rupture into the pleural space and cardiac arrest, managed successfully with endovascular stenting.

Blunt thoracic aortic injury (BTAI) is an uncommon yet serious diagnosis in trauma patients, with high on-scene mortality. BTAI typically occurs from rapid deceleration such as in motor vehicle collisions or high-altitude falls shearing the aorta just proximal to the ligamentum arteriosum. We report a case of a man in his 50s falling from a height of 15 m who presented hypotensive with retrosternal chest pain.

Utility of venous blood gases for the assessment of traumatic shock: a prospective observational study.

Background: ABG samples are often obtained in trauma patients to assess shock severity. Venous blood gas (VBG) sampling, which is less invasive, has been widely used to assess other forms of shock. The study aim was to determine the agreement between VBG and ABG measurements in trauma.

The Road to Survival for Haemodynamically Unstable Patients With Open Pelvic Fractures.

Management of haemodynamically unstable pelvic ring injuries has been simplified into treatment algorithms to streamline care and emergent decision making in order to improve patient outcomes whilst decreasing mortality and morbidity. Pelvic ring injuries are most commonly a result of high-velocity and energy forces that exert trauma to the pelvic bones causing not only damage to the bone but the surrounding soft-tissue, organs, and other structures and are usually accompanied by injuries to other parts of the body resulting in a polytraumatised patient. Open pelvic fractures are a rare subset of pelvic ring fractures that are on the more severe end of the pelvic fracture continuum and usually produce uncontrolled haemorrhage from fractured bone, retroperitoneal haematomas, intraabdominal bleeding from bowel injury, soft tissue injuries to the anus, perineum, and genitals, fractures of the pelvic bones, causing bleeding from cancellous bone, venous, and arterial injuries combined with bleeding from concomitant injuries.

Efficacy of high-flow nasal prong therapy in trauma patients with rib fractures and high-risk features for respiratory deterioration: a randomized controlled trial.

Background: Patients with rib fractures require analgesia, oxygen supplementation and physiotherapy. This combination has been shown to reduce morbidity and mortality due to rib fractures. There has been movement towards the use of high-flow nasal prong (HFNP) oxygen.

Process measure aimed at reducing time to haemorrhage control: outcomes associated with Code Crimson activation in exsanguinating truncal trauma.

Background: Major trauma activation is a process that mobilizes personnel and resources required to care for severely injured patients. Exsanguinating truncal trauma patients require an additional response beyond major trauma activation aimed at expediting haemorrhage control. To address this requirement, 'Code Crimson' (CC) activation was developed.

The swing shift: Opportunity to enhance trauma training in Australia.

Background: Training in trauma forms a fundamental component of general surgical training in Australia. It faces a number of challenges, including the limitations of working hours and increasing use of non-operative management techniques. Adjustment of rosters to encompass a "swing shift" (12pm-midnight) is one proposed solution to maximise exposure of junior surgical doctors to trauma.

Donor white blood cell survival and cytokine profiles following red blood cell transfusion in Australian major trauma patients.

Background: The potential for the co-existence of genetically disparate cells (microchimerism) and associated cytokine profiles following red blood cell (RBC) transfusion in trauma patients has not been well characterized to date. This study investigated the incidence of surviving donor white blood cells (known as transfused-associated microchimerism (TAM)) and cytokine changes following blood transfusion in trauma patients.

Study Design And Methods: Trauma patients with an injury severity score (ISS) >12 who had been transfused between 2012-2016 with at least 5 units of RBC units over a 4 h period were recruited.

Lean psoas area does not correlate with clinical outcomes in moderately to severely injured older people.

Objective: Frailty has been associated with worse outcomes in older trauma patients. Specifically, the utility of lean cross-sectional psoas muscle area (LPA) was examined as a potentially simple objective measure of frailty.

Methods: Five hundred and fifty-four patients over the age of 65 were admitted with trauma between 2011 and 2014.

Controlling hemorrhage in exsanguinating pelvic fractures: Utility of extraperitoneal pelvic packing as a damage control procedure.

Introduction: Exsanguinating pelvic fractures are still associated with a significant mortality rate of 28-60%. Extraperitoneal pelvic packing (EPP) has been proposed as an optimal method of early haemorrhage control. The aim of this study was to determine the effect of EPP compared with angioembolization as a primary intervention for patients with exsanguinating pelvic fracture.

Leukodepleted blood components do not remove the potential for long-term transfusion-associated microchimerism in Australian major trauma patients.

Despite the introduction of leukodepleted blood components, it has been shown that donor leukocyte engraftment (microchimerism) remains a long-term consequence of red blood cell (RBC) transfusion. The incidence of microchimerism may be affected by international disparities in blood processing methods or variations in transfusion practices. This study was conducted to determine the prevalence of microchimerism in Australian trauma patients.

Digital health technology and trauma: development of an app to standardize care.

Background: Standardized practice results in less variation, therefore reducing errors and improving outcome. Optimal trauma care is achieved through standardization, as is evidenced by the widespread adoption of the Advanced Trauma Life Support approach. The challenge for an individual institution is how does one educate and promulgate these standardized processes widely and efficiently? In today's world, digital health technology must be considered in the process.

Identifying the bleeding trauma patient: predictive factors for massive transfusion in an Australasian trauma population.

Background: Military and civilian data would suggest that hemostatic resuscitation results in improved outcomes for exsanguinating patients. However, identification of those patients who are at risk of significant hemorrhage is not clearly defined. We attempted to identify factors that would predict the need for massive transfusion (MT) in an Australasian trauma population, by comparing those trauma patients who did receive massive transfusion with those who did not.

Damage control in the injured patient.

The damage control concept is an essential component in the management of severely injured patients. The principles in sequence are as follows: (1) abbreviated surgical procedures limited to haemorrhage and contamination control; (2) correction of physiological derangements; (3) definitive surgical procedures. Although originally described in the management of major abdominal injuries, the concept has been extended to include thoracic, vascular, orthopedic, and neurosurgical procedures, as well as anesthesia and resuscitative strategies.

The accuracy of focused assessment with sonography in trauma (FAST) in blunt trauma patients: experience of an Australian major trauma service.

Unlabelled: Focused assessment with sonography for trauma (FAST) is a method for detecting haemoperitoneum in trauma patients on initial assessment in the Emergency Department. The aim of this paper is to present an Australian trauma centre's experience with FAST as a tool to screen for intraabdominal free fluid in patient's sustaining blunt truncal trauma.

Method: Over a 63-month period, FAST scans were prospectively studied and compared with findings from a gold-standard investigation, either computed tomography (CT) or laparotomy.

Thoracolumbar fracture in blunt trauma patients: guidelines for diagnosis and imaging.

Objective: The aim of the study was to determine a clinical diagnostic pathway for the imaging of the thoracolumbar spine in blunt trauma patients.

Method: A literature review was undertaken to determine the factors important in the detection of thoracolumbar injury and also to produce a trial protocol, which could be tested retrospectively. Two hundred patients admitted between 1998 and 2000 were reviewed retrospectively to form a database of the relevant clinical features.
