Maritime Applications of Prolonged Casualty Care Sepsis on a Destroyer During Distributed Maritime Operations.

During distributed maritime operations, individual components of the naval force are more geographically dispersed. As the U.S. Navy further develops this concept, smaller vessels may be operating at a significant time and distance away from more advanced medical capabilities. Therefore, during both current and future contested Distributed Maritime Operations, Role 1 maritime caregivers such as Independent Duty Corpsman will have to manage patients for prolonged periods of time. This manuscript presents an innovative approach to teaching complex operational medicine concepts (including Prolonged Casualty Care [PCC]) to austere Role 1 maritime caregivers using a hypothetical scenario involving a patient with sepsis and septic shock. The scenario incorporates the Joint Trauma System PCC Clinical Practice Guidelines (CPG) and other standard references. The scenario includes a stem clinical vignette, expected clinical changes for the affected patient at specific time points (e.g., time 0, 1, 2, and 48h), and expected interventions based on the PCC CPG and available shipboard equipment. Epidemiology of sepsis in the deployed environment is also reviewed. This process also identifies opportunities to improve training, clinical skills sustainment, and standard shipboard medical supplies.

Maritime Applications of Prolonged Casualty Care: A Series Introduction.

The current United States Navy and North Atlantic Treaty Organization (NATO) maritime strategy is coalescing around the concept of Distributed Maritime Operations (DMOs) to prepare for future large-scale combat operations with peer or near-peer competitors. As a result, individual components of naval forces will be more geographically dispersed and oper- ating at a significant time and distance from higher levels of medical care. We developed a series of educational scenarios informed by real-world events to enhance the ability of Role 1 medical caregivers to apply the principles of Prolonged Ca- sualty Care during current routine, crisis, and contingency DMOs.

Between the devil and the deep blue sea: A review of 25 modern naval mass casualty incidents with implications for future Distributed Maritime Operations.

ABSTRACT: In the future, United States Navy Role 1 and Role 2 shipboard medical departments will be caring for patients during Distributed Maritime Operations in both contested and noncontested austere environments; likely for prolonged periods of time. This literature review examines 25 modern naval mass casualty incidents over a 40-year period representative of naval warfare, routine naval operations, and ship-based health service support of air and land operations. Challenges, lessons learned, and injury patterns are identified to prepare afloat medical departments for the future fight. LEVEL OF EVIDENCE: Literature Review, level V.

Pyogenic Pericarditis and Cardiac Tamponade Due to Streptococcus anginosus in a Combat Theater.

Streptococcus anginosus group pericarditis is rare. A 24-year-old male soldier presented for care at a military clinic in Afghanistan with shock and cardiac tamponade requiring emergent pericardial drainage and aeromedical evacuation. We review the patient's case, the need for serial pericardial drainage, and the available literature on this disorder.

Disseminated vaccine-strain varicella as initial presentation of the acquired immunodeficiency syndrome: a case report and review of the literature.

Varicella-zoster virus (VZV) infections have declined in many industrialized countries due to vaccination with the attenuated Oka strain virus. Rare cases of severe, disseminated vaccine-strain VZV infection have occurred in the immunocompromised, although rarely in HIV-infected persons. We describe a man with previously-undiagnosed human immunodeficiency virus (HIV) infection who received VZV vaccination and subsequently presented to a combat hospital in Afghanistan with disseminated varicella, respiratory failure, and sepsis. The patient recovered with ventilator and hemodynamic support, intravenous acyclovir, and empiric antibiotic therapy. DNA sequencing detected Oka strain virus from patient blood specimens. Although safe in most populations, the VZV vaccine may cause life-threatening disease in immunocompromised patients. Improved detection of HIV infection may be useful in preventing such cases.
