Resuscitation in a multiple casualty event

Advancing the scientific study of prehospital mass casualty response through a Translational Science process: the T1 scoping literature review stage

PURPOSE

The European Union Horizon 2020 research and innovation funding program awarded the NIGHTINGALE grant to develop a toolkit to support first responders engaged in prehospital (PH) mass casualty incident (MCI) response. To reach the projects' objectives, the NIGHTINGALE consortium used a Translational Science (TS) process. The present work is the first TS stage (T1) aimed to extract data relevant for the subsequent modified Delphi study (T2) statements.

METHODS

The authors were divided into three work groups (WGs) MCI Triage, PH Life Support and Damage Control (PHLSDC), and PH Processes (PHP). Each WG conducted simultaneous literature searches following the PRISMA extension for scoping reviews. Relevant data were extracted from the included articles and indexed using pre-identified PH MCI response themes and subthemes.

RESULTS

The initial search yielded 925 total references to be considered for title and abstract review (MCI Triage 311, PHLSDC 329, PHP 285), then 483 articles for full reference review (MCI Triage 111, PHLSDC 216, PHP 156), and finally 152 articles for the database extraction process (MCI Triage 27, PHLSDC 37, PHP 88). Most frequent subthemes and novel concepts have been identified as a basis for the elaboration of draft statements for the T2 modified Delphi study.

CONCLUSION

The three simultaneous scoping reviews allowed the extraction of relevant PH MCI subthemes and novel concepts that will enable the NIGHTINGALE consortium to create scientifically anchored statements in the T2 modified Delphi study.

The Multiple Casualty Scenario: Role of the Anesthesiologist

Purpose of Review

Mass casualty disasters (natural and man-made) present an acute, critical situation that taxes healthcare resources and clinician acumen. This review summarizes the characteristics and management skill sets that anesthesiologists possess that make them valuable clinicians during mass casualty events and why we as anesthesiologists must continually educate ourselves on this important topic.

Recent Findings

Anesthesiologists should be involved in all aspects of emergency preparedness—mitigation, planning, response, and recovery. The anesthesia department should have a plan for how it will deal with managing patients during natural and man-made (unintentional or intentional) disasters, one that takes into account a risk hazard analysis and institutional goals. Unfortunately, most practicing anesthesiologists have not had training and ongoing education for such events, and few academic centers train anesthesiology residents and staff to prepare for mass casualty scenarios.

Summary

The everyday clinical practice of anesthesiologists involves the utilization of some of the skills (vascular access, tracheal intubation) commonly required to successfully manage mass casualty scenarios. Anesthesiologists’ knowledge of anti-cholinesterases makes them subject matter experts on nerve agent poisoning, and their experience managing trauma patients will serve them well, depending on the nature of the mass casualty event. Practicing anesthesiologists however need to continually educate themselves on their role during mass casualty events. and current anesthesiology residency programs should develop a curriculum and incorporate simulation training to better prepare future generations of anesthesiologists.

What is new in the blood bank for trauma resuscitation

PURPOSE OF REVIEW

The aim of the present review was to describe recent changes in blood banking thinking, practice, and products that affect trauma care.

RECENT FINDINGS

Prompt balanced hemostatic resuscitation of major hemorrhage from trauma improves outcome and reduces blood use. New blood processes and products can help deliver appropriate doses of procoagulant plasma and platelets quicker and more safely. New processes include holding larger inventories of thawed plasma with risk of wastage and rapid plasma thawers. New products in the blood bank include group A or group A low-titer B thawed plasma and AB or A liquid (never-frozen) plasma for resuscitation, prepooled cultured whole blood-derived platelets in plasma, and prepooled cryoprecipitate in varying pool sizes. Single-donor apheresis or pooled whole blood-derived platelets in additive solution, designed to reduce plasma-related transfusion reactions, are also increasingly available but are not an appropriate blood component for hemorrhage control resuscitation because they reduce the total amount of administered plasma coagulation factors by 10%.

SUMMARY

Early initiation of balanced massive transfusion protocols leading to hemostatic resuscitation is lifesaving. Changing blood product availability and composition will lead to higher complexity of massive transfusion. It is critical that anesthesiologists understand the composition of the available new blood products to use them correctly.

Portable ultrasound in disaster triage: a focused review

Ultrasound technology has become ubiquitous in modern medicine. Its applications span the assessment of life-threatening trauma or hemodynamic conditions, to elective procedures such as image-guided peripheral nerve blocks. Sonographers have utilized ultrasound techniques in the pre-hospital setting, emergency departments, operating rooms, intensive care units, outpatient clinics, as well as during mass casualty and disaster management. Currently available ultrasound devices are more affordable, portable, and feature user-friendly interfaces, making them well suited for use in the demanding situation of a mass casualty incident (MCI) or disaster triage. We have reviewed the existing literature regarding the application of sonology in MCI and disaster scenarios, focusing on the most promising and practical ultrasound-based paradigms applicable in these settings.
