Tourniquets are used on distal limb segments. We examined calf and forearm use of four thigh-effective, commercial tourniquets with different widths and tightening systems: 3.8 cm windlass Combat Application Tourniquet® (CAT, combattourrniquet.com) and Special Operations Forces® Tactical Tourniquet-Wide (SOFTTW, www.tacmedsolutions.com), 3.8 cm ratchet Ratcheting Medical Tourniquet - Pediatric (RMT-P, www.ratchetingbuckles. com), and 10.4 cm elastic Stretch-Wrap-And-Tuck Tourniquet® (SWATT, www.swattourniquet.com). ⋯ All four designs can be effective on distal limb segments, the SWATT doing so with the lowest pressures and least pressure losses over time. The pressure change from Occlusion to Completion varies by tourniquet tightening system and can involve a pressure decrease with the windlass tightening systems. Pressure losses occur in as little as 120 seconds following Completion and so can loss of Occlusion. This is especially true for nonelastic strap tourniquet designs.

Excited delirium syndrome (ExDS) is a term used to describe patients experiencing a clinical condition characterized by bizarre and aggressive behavior, often in association with the use of chronic sympathomimetic drug abuse. The agitated and disruptive behavior of persons with ExDS often results in a call to police resulting in an arrest for disorderly conduct. The suspect's inability to comply with police commands during the arrest frequently results in a struggle and the use of physical or chemical control measures, including the use of conductive energy weapons (CEWs). ⋯ Once sedated, patients should undergo a screening medical assessment and undergo initial treatment for conditions such as hyperthermia and dehydration. All patients exhibiting signs of ExDS should be transported rapidly to a medical treatment facility for further evaluation and treatment. This article reviews the epidemiology, clinical presentation, diagnosis, and treatment options for ExDS.

The United States has achieved unprecedented survival rates, as high as 98%, for casualties arriving alive at the combat hospital. Our military medical personnel are rightly proud of this achievement. Commanders and Servicemembers are confident that if wounded and moved to a Role II or III medical facility, their care will be the best in the world. ⋯ Observations for this report were collected from December 2013 to January 2014 and were obtained directly from deployed prehospital providers, medical leaders, and combatant leaders. Significant progress has been made between these two reports with the establishment of a Prehospital Care Division within the JTTS, development of a prehospital trauma registry and weekly prehospital trauma conferences, and CJOA-A theater guidance and enforcement of prehospital documentation. Specific prehospital trauma-care achievements include expansion of transfusion capabilities forward to the point of injury, junctional tourniquets, and universal approval of tranexamic acid.

The current Tactical Combat Casualty Care (TCCC) Guidelines recommend parenteral promethazine as the single agent for the treatment of opioid-induced nausea and/or vomiting and give a secondary indication of "synergistic analgesic effect." Promethazine, however, has a well-documented history of undesired side effects relating to impairment and dysregulation of the central and autonomic nervous systems, such as sedation, extrapyramidal symptoms, dystonia, impairment of psychomotor function, neuroleptic malignant syndrome, and hypotension. These may be particularly worrisome in the combat casualty. Additionally, since 16 September 2009, there has been a US Food and Drug Administration (FDA) black box warning for the injectable form of promethazine, due to "the risk of serious tissue injury when this drug is administered incorrectly." Conversely, ondansetron, which is now available in generic form, has a well-established favorable safety profile and demonstrated efficacy in undifferentiated nausea and vomiting in the emergency department and prehospital settings. ⋯ Ondansetron is available in parenteral form and an orally disintegrating tablet, providing multiple safe and effective routes of administration. Despite the fact that it is an off-label use, ondansetron is being increasingly given for acute, undifferentiated nausea and vomiting and is presently being used in the field on combat casualties by some US and Allied Forces. Considering the risks involved with promethazine use, and the efficacy and safety of ondansetron and ondansetron?s availability in a generic form, we recommend removing promethazine from the TCCC Guidelines and replacing it with ondansetron.

Law enforcement tactical incidents involve high-risk operations that exceed the capabilities of regular, uniformed police. Despite the existence of tactical teams for 50 years, little is known about the frequency or nature of emergency medical services (EMS) response to tactical events in the United States. The purpose of this study was to perform a descriptive analysis of tactical events reported to a national EMS database. ⋯ Approximately 11 EMS responses in support of law enforcement tactical operations occur daily in the United States. The majority occur in homes and involve a single patient. Advanced airway procedures are required in a minority of patients. Cardiac arrest is rare and occurs prior to EMS response in the majority of cases. Better understanding of the nature and location of EMS responses to tactical incidents is required to develop consistent EMS policies in support of law enforcement tactical operations.
