International cross-sectional survey on current and updated definitions of intra-abdominal hypertension and abdominal compartment syndrome.

Background: The Abdominal Compartment Society (WSACS) established consensus definitions and recommendations for the management of intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) in 2006, and they were last updated in 2013. The WSACS conducted an international survey between 2022 and 2023 to seek the agreement of healthcare practitioners (HCPs) worldwide on current and new candidate statements that may be used for future guidelines.

Methods: A self-administered, online cross-sectional survey was conducted under the auspices of the WSACS to assess the level of agreement among HCPs over current and new candidate statements.

Circulatory Trauma: A Paradigm for Understanding the Role of Endovascular Therapy in Hemorrhage Control.

The pathophysiology of traumatic hemorrhage is a phenomenon of vascular disruption and the symptom of bleeding represents one or more vascular injuries. In the Circulatory Trauma paradigm traumatic hemorrhage is viewed as injury to the circulatory system and suggests the underlying basis for endovascular hemorrhage control techniques. The question "Where is the patient bleeding?" is replaced by "Which blood vessels are disrupted?" and stopping bleeding becomes a matter of selective vessel access and vascular flow control.

The Role of TEG and ROTEM in Damage Control Resuscitation.

Trauma-induced coagulopathy is associated with very high mortality, and hemorrhage remains the leading preventable cause of death after injury. Directed methods to combat coagulopathy and attain hemostasis are needed. The available literature regarding viscoelastic testing, including thrombelastography (TEG) and rotational thromboelastometry (ROTEM), was reviewed to provide clinically relevant guidance for emergency resuscitation.

Limitations of Available Blood Products for Massive Transfusion During Mass Casualty Events at US Level 1 Trauma Centers.

Introduction: Exsanguination remains a leading cause of preventable death in traumatically injured patients. To better treat hemorrhagic shock, hospitals have adopted massive transfusion protocols (MTPs) which accelerate the delivery of blood products to patients. There has been an increase in mass casualty events (MCE) worldwide over the past two decades.

Back to the Future: Whole Blood Resuscitation of the Severely Injured Trauma Patient.

Following advances in blood typing and storage, whole blood transfusion became available for the treatment of casualties during World War I. While substantially utilized during World War II and the Korean War, whole blood transfusion declined during the Vietnam War as civilian centers transitioned to blood component therapies. Little evidence supported this shift, and recent conflicts in Iraq and Afghanistan have renewed interest in military and civilian applications of whole blood transfusion.

Time to Hemorrhage Control in a Hybrid ER System: Is It Time to Change?

Time to hemorrhage control is critical, as mortality in patients with severe hemorrhage that arrive to trauma centers with sign of life remains over 40%. Prompt identification and management of severe hemorrhage is paramount to reducing mortality. In traditional US trauma systems, the early hospital course of a severely hemorrhaging patient typically proceeds from the trauma resuscitation bay to the operating room or angiography suite with a potential stop for radiological imaging.

Endovascular Resuscitation and Trauma Management (EVTM)-Practical Aspects and Implementation.

In recent years there has been a tremendous increase in hemorrhage control by endovascular methods. Traumatic and non-traumatic hemorrhage is being more frequently managed with endografts, embolization agents, and minimal invasive methods. These methods initially were used in hemodynamically stable patients only, whereas now these are being implemented in acute settings and hemodynamically unstable patients.

A “human-proof pointy-end”: a robotically applied hemostatic clamp for care-under-fire.

Providing the earliest hemorrhage control is now recognized as a shared responsibility of all members of society, including both the lay public and professionals, consistent with the Stop the Bleed campaign. However, providing early hemorrhage control in a hostile environment, such as the scene of a mass shooting, is extremely challenging. In such settings, the first access to a bleeding victim may be robotic.

Abbreviated closure for remote damage control laparotomy in extreme environments: A randomized trial of sutures versus wound clamps comparing terrestrial and weightless conditions.

Introduction: Far-Forward Damage Control Laparotomies (DCLs) might provide direct-compression of visceral hemorrhage, however, suturing is a limiting factor, especially for non-physicians. We thus compared abbreviated skin closures comparing skin-suture (SS) versus wound-clamp (WC), on-board a research aircraft in weightlessness (0g) and normal gravity (1g).

Methods: Surgeons conducted DCLs on a surgical-simulator; onboard the hangered-aircraft (1g), or during parabolic flight (0g), randomized to either WC or SS.

Accuracy of clinical, laboratory, and computed tomography findings for identifying hollow viscus injury in blunt trauma patients with unexplained intraperitoneal free fluid without solid organ injury.

Background: We sought to define the accuracy of findings for detecting hollow viscus injury (HVI) in patients with blunt abdominal trauma (BAT) and unexplained intra-peritoneal free fluid without solid organ injury (UIPFFWSOI).

Methods: We screened all consecutive hemodynamically stable patients presenting to a quaternary-care trauma-centre who had an abdominal computed tomography (CT) scan for BAT and UIPFFWSOI (January 2007-December 2014).

Results: Of 3796 patients identified during the study period, 39 presented with UIPFFWSOI.

Intra-abdominal hypertension and the abdominal compartment syndrome: updated consensus definitions and clinical practice guidelines from the World Society of the Abdominal Compartment Syndrome.

Purpose: To update the World Society of the Abdominal Compartment Syndrome (WSACS) consensus definitions and management statements relating to intra-abdominal hypertension (IAH) and the abdominal compartment syndrome (ACS).

Methods: We conducted systematic or structured reviews to identify relevant studies relating to IAH or ACS. Updated consensus definitions and management statements were then derived using a modified Delphi method and the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) guidelines, respectively.

Can cervical spine computed tomography assist in detecting occult pneumothoraces?

Introduction: Screening CT often detects posttraumatic pneumothoraces that were not diagnosed on a preceding supine anteroposterior chest radiograph (occult pneumothoraces (OPTXs)). Because abdominal CT imaging misses OPTXs in the upper thorax, the objective of this study was to evaluate the utility of cervical spine (C-spine) CT screening for diagnosing OPTXs.

Methods: A dual-institution (Foothills Medical Centre and Grady Memorial Hospital) retrospective review of consecutive OPTXs was performed.
