Resuscitative thoracotomy (RT) is a critical, time-sensitive procedure that may be performed by emergency medicine (EM) physicians. The left anterolateral thoracotomy (LAT) is the technique traditionally used in the United States. However, its limited exposure may hinder effective intervention. The modified bilateral clamshell thoracotomy (MCT), developed by Barts Health NHS Trust clinicians at London's Air Ambulance (LAA), offers greater exposure and may be more suitable for EM physicians. This study aimed to determine the optimal RT technique for EM physicians while also assessing technical challenges, procedural concerns, and provider preferences. EM staff and resident physicians from a level one trauma center participated after receiving standardized training on both MCT and LAT techniques. Participants were randomized to perform each technique on live tissue swine with a novel penetrating injury model. Success was defined as heart delivery from the pericardial sac, cardiac hemorrhage control, and full thoracic aorta occlusion. The primary outcome was time to successful RT completion. Secondary outcomes included procedural success rates, adequate exposure, hemorrhage control, cross-clamping success, iatrogenic injuries, and participant feedback. Ten EM physicians completed the study. There was not a significant difference in time to successful completion of the MCT and LAT techniques (585 s vs 664.9 s, hazard ratio 0.63, CI 95 % 0.27 to 1.49). Success rates were similar (80 % vs 70 %, difference − 10 %, 95 % CI -50.6 % to 30.6 %). Provider procedure preference favored the MCT over the LAT (100 % vs 0 %). Though participants were more experienced with the LAT, the MCT performed as well and was universally preferred. The MCT may be the ideal technique for EM physicians confronting a penetrating thoracic injury with pulselessness or extremis in the absence of a surgical provider.

Amid the ongoing U.S. opioid crisis, achieving safe and effective chronic pain management while reducing opioid-related morbidity and mortality is likely to require multi-level efforts across health systems, including the Military Health System (MHS), Department of Veterans Affairs (VA), and civilian sectors. We conducted a series of qualitative panel discussions with national experts to identify core challenges and elicit recommendations toward improving the safety of opioid prescribing in the U.S. We invited national experts to participate in qualitative panel discussions regarding challenges in opioid risk mitigation and how best to support providers in delivery of safe and effective opioid prescribing across MHS, VA, and civilian health systems. Eighteen experts representing primary care, emergency medicine, psychology, pharmacy, and public health/policy participated. Six qualitative panel discussions were conducted via teleconference with experts. Transcripts were coded using team-based qualitative content analysis to identify key challenges and recommendations in opioid risk mitigation. Panelists provided insight into challenges across multiple levels of the U.S. health system, including the technical complexity of treating chronic pain, the fraught national climate around opioids, the need to integrate surveillance data across a fragmented U.S. health system, a lack of access to non-pharmacological options for chronic pain care, and difficulties in provider and patient communication. Participating experts identified recommendations for multi-level change efforts spanning policy, research, education, and the organization of healthcare delivery. Reducing opioid risk while ensuring safe and effective pain management, according to participating experts, is likely to require multi-level efforts spanning military, veteran, and civilian health systems. Efforts to implement risk mitigation strategies at the patient level should be accompanied by efforts to increase education for patients and providers, increase access to non-pharmacological pain care, and support use of existing clinical decision support, including state-level prescription drug monitoring programs.

Toxic alcohol ingestion is a rare but serious condition that carries with it a high rate of morbidity and mortality. This review highlights the pearls and pitfalls of toxic alcohol ingestion, including presentation, diagnosis, and management in the emergency department (ED) based on current evidence. Toxic alcohols include ethylene glycol, methanol, isopropyl alcohol, propylene glycol, and diethylene glycol. These substances can be found in several settings including hospitals, hardware stores, and the household, and ingestion can be accidental or intentional. Toxic alcohol ingestion presents with various degrees of inebriation, acidemia, and end-organ damage depending on the substance. Timely diagnosis is critical to prevent irreversible organ damage or death and is based primarily on clinical history and consideration of this entity. Laboratory evidence of toxic alcohol ingestion includes worsening osmolar gap or anion-gap acidemia and end organ injury. Treatment depends on the ingestion and severity of illness but includes alcohol dehydrogenase blockade with fomepizole or ethanol and special considerations for the initiation of hemodialysis. An understanding of toxic alcohol ingestion can assist emergency clinicians in diagnosing and managing this potentially deadly disease.

Ketamine administration in patients experiencing or at risk for hypotension is common based upon the presumption of this agent's favorable hemodynamic profile. The Compensatory Reserve Measurement (CRM) is a novel algorithm that accurately tracks systemic adequacy for delivery of oxygen (DO2) to the tissues. We present a case series of trauma patients receiving ketamine with CRM measurements to offer insight into the DO2 during resuscitation. We captured vital signs along with analog arterial waveform data from trauma patients meeting major activation criteria using a prospective study design. Study team members tracked interventions and vital signs including systolic blood pressure (SBP), mean arterial pressure (MAP), and heart rate (HR) throughout their emergency department stay. Our study included 8 patients who received ketamine for intubation or analgesia (20-300 mg) and had adequate data for analysis. Most were male (88%) with a median age of 28. The most common mechanisms of injury were motor vehicle collisions (MVCs) (38%) and gunshot wounds (38%). After ketamine administration SBP, MAP, and HR all increased while the CRM exhibited minimal change. SBP, MAP, and HR generally appeared to increase while the CRM remained unchanged. Our findings suggest that while standard vital sign measurements appear to increase, ketamine may not improve delivery of oxygen to the tissues. This warrants further study to better understand the effects of ketamine on hemodynamics.

ObjectivesThis project seeks to improve providers’ practices and patient outcomes from prehospital (ie, ambulance-based) trauma care in a middle-income country using a novel implementation strategy to introduce a bundled clinical intervention.DesignWe conduct a two-arm, controlled, mixed-methods, hybrid type II study.SettingThis study was conducted in the Western Cape Government Emergency Medical Services (EMS) system of South Africa.InterventionsWe pragmatically implemented a simplified prehospital bundle of trauma care (with five core elements) using a novel workplace-based, peer-to-peer, rapid training format. We assigned the intervention and control sites.Outcome measuresWe assessed implementation effectiveness among EMS providers and stakeholders, using the RE-AIM framework. Clinical effectiveness was assessed at the patient level, using changes in Shock Index x Age (SIxAge). Indices and cut-offs were established a priori. We performed a difference-in-differences (D-I-D) analysis with a multivariable mixed effects model.Results198 of 240 (82.5%) EMS providers participated, 93 (47%) intervention and 105 (53%) control, with similar baseline characteristics. The overall implementation effectiveness was excellent (80.6%): reach was good (65%), effectiveness was excellent (87%), implementation fidelity was good (72%) and adoption was excellent (87%). Participants and stakeholders generally reported very high satisfaction with the implementation strategy citing that it was a strong operational fit and effective educational model for their organisation. A total of 770 patients were included: 329 (42.7%) interventions and 441 (57.3%) controls, with no baseline differences. Intervention arm patients had more improved SIxAge compared with control at 4 months, which was not statistically significant (−1.4 D-I-D; p=0.35). There was no significant difference in change of SIxAge over time between the groups for any of the other time intervals (p=0.99).ConclusionsIn this quasi-experimental trial of bundled care using the novel workplace rapid training approach, we found overall excellent implementation effectiveness but no overall statistically significant clinical effectiveness.

Head injuries frequently occur in combat. Tactical Combat Casualty Care (TCCC) guidelines recommend pre-hospital use of ketamine for analgesia. Yet the use of this medication in patients with head injuries remains controversial, particularly among pediatric patients. We compare survival to hospital discharge rates among pediatric head injury subjects who received prehospital ketamine versus those who did not. We queried the Department of Defense Trauma Registry (DODTR) for all pediatric (<18 years of age) subjects from January 2007 to January 2016. We performed a sub-analysis of subjects with an abbreviated injury severity score for the head of 3 (serious) or higher and at least one documented Glasgow Coma Score (GCS) ≤13. Of the 3439 pediatric patients within our dataset, 555 subjects met inclusion criteria for head injury – 36 (6.5%) received prehospital ketamine versus 519 (93.5%) who did not. There was no significant difference noted between groups regarding median age (10 versus 8, p = 0.259), percent male gender (72.2% versus 76.3%, p = 0.579), mechanism of injury (p = 0.143), median composite injury scores (22 versus 20, p = 0.082), median ventilator-free days (28 versus 27, p = 0.068), median ICU-free days (27.5 versus 27, p = 0.767), median hospital days (3.5 versus 4, p = 0.876) or survival to discharge (66.7% versus 70.7%, p = 0.607). Within this data set, we were unable to detect any differences in mortality among pediatric head trauma subjects administered ketamine compared to subjects not receiving this medication in the prehospital setting.

In this case report, a 2-year-old girl ingested \"a couple of fingers full\" of Armor Etch glass etching cream (21%-27% ammonium bifluoride) and was taken to the emergency department after 5 episodes of vomiting within an hour of ingestion. Upon arrival to the emergency department (ED) 2 hours after the time of ingestion, the patient was no longer vomiting, and had normal vital signs, a normal physical examination, normal electrocardiogram finding, and an ionized calcium level of 1.21 mmol/L (reference range, 1.24-1.40 mmol/L). The patient did not have a history of vitamin D deficiency, renal failure, or the consumption of other xenobiotics known to cause hypokalemia.

Introduction Analysis of injuries during military operations has focused on those related to combat. Non-combat complaints have received less attention, despite the need for many troops to be evacuated for non-battle illnesses in Iraq. This study aims to further characterize the disease and non-battle injuries (DNBIs) seen at a tertiary combat hospital and to describe the types of procedures and medications used in the management of these cases. In this observational study, patients were enrolled from a convenience sample with non-combat-related diseases and injuries who were evaluated in the emergency department (ED) of a US military tertiary hospital in Iraq from 2007-2008. The treating emergency physician (EP) used a data collection form to enroll patients that arrived to the ED whose injury or illness was unrelated to combat. Data were gathered on 1,745 patients with a median age of 30 years; 84% of patients were male and 85% were US military personnel. The most common diagnoses evaluated in the ED were abdominal disorders, orthopedic injuries, and headache. Many cases involved intravenous access, laboratory testing, and radiographic testing. Procedures performed included electrocardiogram, lumbar puncture, and intubation. Disease and non-battle traumatic injuries are common in a tertiary combat hospital. Emergency providers working in austere settings should have the diagnostic and procedural skills to evaluate and treat DNBIs. Bebarta VS , Mora AG , Ng PC , Mason PE , Muck A , Maddry JK .

Air Force Critical Care Air Transport Teams (CCATTs) provide fixed-wing aeromedical evacuation for combat casualties. Multiple studies have evaluated CCATT trauma patients; however, nearly 50% of patients medically evacuated from combat theaters are for nontraumatic medical illnesses to include stroke, myocardial infarctions, overdose, and pulmonary emboli. Published data are limited regarding illness types, in-flight procedures, and adverse events. The objective of our study was to characterize patients with nontraumatic medical illnesses transferred via CCATT to include a description of in-flight procedures and events. We performed a retrospective review of CCATT medical records of patients with nontraumatic medical illnesses transported via CCATT from theater of operations to Landstuhl Regional Medical Center between January 2007 and April 2015. We abstracted data from CCATT records to include demographics, description of current illness, vital signs, labs, in-flight procedures and medications, and in-flight adverse events. Following descriptive analysis, comparative tests were performed based on service status of patients and primary diagnoses. We reviewed 672 records of critically ill medical patients transported via CCATT, most of whom were male (90%, n = 606). Approximately 56% of the patients were U.S. active duty members; the remainder included U.S. contractors and civilians, and foreign citizens or unknown. The three categories (active duty, contractor/civilian, foreign/unknown) significantly differed from one another in age. Over half of the patients received a primary or secondary cardiac diagnosis. The most common in-flight procedures and medications included supplementary oxygenation, anticoagulant/antiplatelet medications, analgesics, and ventilation. Up to 20% of patients required continuous medication infusions other than analgesics. Patients most frequently experienced in-flight complications related to their primary diagnoses. Fifty-six percent (672) of 1,209 CCATT records that were queried were of patients with medical conditions. The most common primary diagnoses of CCATT medical patients were cardiac, pulmonary, and neurological in etiology. Mechanical ventilation and continuous medication infusions were required in approximately 20% of patients. The data provided by this study may assist in guiding future CCATT training requirements and resource allocation, as well as clinical practice guideline development.

Between 2001 and 2009, opioid analgesic prescriptions in the Military Health System quadrupled to 3.8 million. The sheer quantity of opioid analgesics available sets the stage for issues related to misuse, abuse, and diversion. To address this issue, the Department of Defense implemented several directives and clinical guidelines to improve access to appropriate pain care and safe opioid prescribing. Unfortunately, little has been done to characterize changing patterns of opioid use in active duty service members (ADSM), so little is known about how combat operations and military health care policy may have influenced this significant problem. We examined changes in opioid use for ADSM between 2006 and 2014, compared trends with the civilian population, and explored the potential role of military-specific factors in changes in opioid use in the Military Health System. After obtaining Institutional Review Board approval, administrative prescription records (Pharmacy Data Transaction Records) for non-deployed ADSM were used to determine the number of opioid prescriptions dispensed each year and the proportion of ADSM who received at least one prescription per month between 2006 and 2014. Based on the observation and the literature, we identified December 2011 as the demarcation point (the optimal point to identify the downturn in opioid use) and used it to compare opioid use trends before and after. We used an autoregressive forecast model to verify changes in opioid use patterns before and after 2011. Several interrupted time series models examined whether military system-level factors were associated with changes in opioid use. Between 2006 and 2014, 1,516,979 ADSM filled 7,119,945 opioid prescriptions, either in military treatment facilities or purchased through TRICARE. Both active duty and civilian populations showed signs of decreasing use after 2011, but this change was much more pronounced among ADSM. The forecast model showed a significant difference after 2011 between the projected and actual proportion of ADSM filling an opioid prescription, confirming 2011 as a point of divergence in opioid use. Interrupted time series models showed that the deflection point was associated with significant decreases. A significant increase of 0.261% in opioid prescriptions was seen for every 1,000 wounded in action service members in a given month. Troops returning from Operation Enduring Freedom, Operation Iraqi Freedom, or Operation New Dawn did not appear to influence the rates of use. Even after accounting for returning troops from Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn and wounded in action counts, the deflection point was associated with a lower proportion of ADSM who filled an opioid prescription, leading to a decrease of 1.61% by the end of the observation period (December 2014). After December 2011, opioid use patterns significantly decreased in both civilian and ADSM populations, but more so in the military population. Many factors, such as numbers of those wounded in action and the structural organization of the Military Health System, may have caused the decline, although more than likely the decrease was influenced by many factors inside and outside of the military, including policy directives and cultural changes.
