Management of children in the deployed intensive care unit at Camp Bastion, Afghanistan
Background The deployed Intensive Therapy Unit (ITU) in the British military field hospital in Camp Bastion, Afghanistan, admits both adults and children. The purpose of this paper is to review the paediatric workload in the deployed ITU and to describe how the unit copes with the challenge of looking after critically injured and ill children.
Methods Retrospective review of patients <16 years of age admitted to the ITU in the British military field hospital in Camp Bastion, Afghanistan, over a 1-year period from April 2011 to April 2012.
Results 112/811 (14%) admissions to the ITU were paediatric (median age 8 years, IQR 6–12, range 1–16).80/112 were trauma admissions, 13 were burns, four were non-trauma admissions and 15 were readmissions.
Mechanism of injury in trauma was blunt in 12, blast (improvised explosive device) in 45, blast (indirect fire) in seven and gunshot wound in 16. Median length of stay was 0.92 days (IQR 0.45–2.65). 82/112 admissions (73%) were mechanically ventilated, 16/112 (14%) required inotropic support. 12/112 (11%) died before unit discharge. Trauma scoring was available in 65 of the 80 trauma admissions. Eight had Injury Severity Score or New Injury Severity Score >60, none of whom survived. However, of the 16 patients with predicted mortality >50% by Trauma Injury Severity Score, seven survived. Seven cases required specialist advice and were discussed with the Birmingham Children’s Hospital paediatric intensive care retrieval service. The mechanisms by which the Defence Medical Services support children admitted to the deployed adult ITU are described, including staff training in clinical, ethical and child protection issues, equipment, guidelines and clinical governance and rapid access to specialist advice in the UK.
Conclusions With appropriate support, it is possible to provide intensive care to children in a deployed military ITU.
Infectious, traumatic, or neoplastic processes in the chest often result in fluid collections within the pleural, parenchymal, or mediastinal spaces. The same fundamental principles that guide drainages of the abdomen can be applied to the chest. This review discusses various pathologic conditions of the thorax that can result in the abnormal accumulation of fluid or air, and their management using image-guided methods.
Amelioration of Acute Sequelae of Blast Induced Mild Traumatic Brain Injury by N-Acetyl Cysteine: A Double- Blind, Placebo Controlled Study
Background: Mild traumatic brain injury (mTBI) secondary to blast exposure is the most common battlefield injury in Southwest Asia. There has been little prospective work in the combat setting to test the efficacy of new countermeasures. The goal of this study was to compare the efficacy of N-acetyl cysteine (NAC) versus placebo on the symptoms associated with blast exposure mTBI in a combat setting.
Methods: This study was a randomized double blind, placebo-controlled study that was conducted on active duty service members at a forward deployed field hospital in Iraq. All symptomatic U.S. service members who were exposed to significant ordnance blast and who met the criteria for mTBI were offered participation in the study and 81 individuals agreed to participate. Individuals underwent a baseline evaluation and then were randomly assigned to receive either N- acetyl cysteine (NAC) or placebo for seven days.
4 g per os puis 18-24h après 2X2 g jusqu'à J4 puis 1,5 g X2 jusqu'à J7
Each subject was re-evaluated at 3 and 7 days. Outcome measures were the presence of the following sequelae of mTBI: dizziness, hearing loss, headache, memory loss, sleep disturbances, and neurocognitive dysfunction. The resolution of these symptoms seven days after the blast exposure was the main outcome measure in this study. Logistic regression on the outcome of ‘no day 7 symptoms’ indicated that NAC treatment was significantly better than placebo (OR = 3.6, p = 0.006). Secondary analysis revealed subjects receiving NAC within 24 hours of blast had an 86% chance of symptom resolution with no reported side effects versus 42% for those seen early who received placebo.
Conclusion: This study, conducted in an active theatre of war, demonstrates that NAC, a safe pharmaceutical countermeasure, has beneficial effects on the severity and resolution of sequelae of blast induced mTBI. This is the first demonstration of an effective short term countermeasure for mTBI. Further work on long term outcomes and the potential use of NAC in civilian mTBI is warranted

Chemical Terrorism for the Intensivist
The use of chemical agents for terrorist attacks or military warfare is a major concern at the presenttime. Chemical agents can cause signiﬁcant morbidity, are relatively inexpensive, and are easy to store and use.Weaponization of chemical agents is only limited by the physicochemical properties of some agents. Recent incidentsinvolving toxic industrial chemicals and chemical terrorist attacks indicate that critical care services are frequentlyutilized. For obvious reasons, the critical care literature on chemical terrorism is scarce. This article reviews the clinicalaspects of diagnosing and treating victims of chemical terrorism while emphasizing the critical care management. Theintensivist needs to be familiar with the chemical agents that could be used in a terrorist attack. The military classiﬁcation divides agents into lung agents, blood agents, vesicants, and nerve agents. Supportive critical care is the cornerstoneof treatment for most casualties, and dramatic recovery can occur in many cases. Speciﬁc antidotes are available forsome agents, but even without the antidote, aggressive intensive care support can lead to favorable outcome in manycases. Critical care and emergency services can be overwhelmed by a terrorist attack as many exposed but not ill willseek care.
Death on the battlefield (2001-2011): Implications for the future of combat casualty care.
Une publication n'est pas récente mais qui a pour intérêt d'actualiser la question à l'aulne de la dizaine d'années de combats asymétriques en afghanistan et en irak.
BACKGROUND: Critical evaluation of all aspects of combat casualty care, including mortality, with a special focus on the incidence and causes of potentially preventable deaths among US combat fatalities, is central to identifying gaps in knowledge, training, equipment, and execution of battlefield trauma care. The impetus to produce this analysis was to develop a comprehensive perspective of battlefield death, concentrating on deaths that occurred in the preYmedical treatment facility (pre-MTF) environment.
METHODS: The Armed Forces Medical Examiner Service Mortality Surveillance Division was used to identify Operation Iraqi Freedom and operation Enduring Freedom combat casualties from October 2001 to June 2011 who died from injury in the deployed environment.bThe autopsy records, perimortem records, photographs on file, and Mortality Trauma Registry of the Armed Forces Medical Examiner Service were used to compile mechanism of injury, cause of injury, medical intervention performed, Abbreviated Injury Scale (AIS)score, and Injury Severity Score (ISS) on all lethal injuries. All data were used by the expert panel for the conduct of the potential for injury survivability assessment of this study.
RESULTS: For the study interval between October 2001 and June 2011, 4,596 battlefield fatalities were reviewed and analyzed. The stratificationof mortality demonstrated that 87.3% of all injury mortality occurred in the pre-MTF environment. Of the pre-MTF deaths, 75.7%(n = 3,040) were classified as nonsurvivable, and 24.3% (n = 976) were deemed potentially survivable (PS). The injury/physiologic focus of PS acute mortality was largely associated with hemorrhage (90.9%). The site of lethal hemorrhage was truncal (67.3%), followed by junctional (19.2%) and peripheral-extremity (13.5%) hemorrhage.
CONCLUSION: Most battlefield casualties died of their injuries before ever reaching a surgeon. As most pre-MTF deaths are nonsurvivable, mitigation strategies to impact outcomes in this population need to be directed toward injury prevention. To significantly impact the outcome of combat casualties with PS injury, strategies must be developed to mitigate hemorrhage and optimize airway management or reduce the time interval between the battlefield point of injury and surgical intervention. Understanding battlefield mortality is a vital component of the military trauma system. Emphasis on this analysis should be placed on trauma system optimization, evidence-based improvements in Tactical Combat Casualty Care guidelines, data-driven research, and development to remediate gaps in care and relevant training and equipment enhancements that will increase the survivability of the fighting force.
Point-of-injury use of reconstituted freeze dried plasma as a resuscitative fluid: A special report for prehospital trauma care
Glassberg E. et All. J J Trauma Acute Care Surg. 2013;75(Suppl 2):S111YS111.
La prise en charge d'hémorrragie catastrophique en phase préhospitalière est particulièrement complexe. Ces dernières années la mise en place d'un réseau structuré de prise en charge, 'application de procédures spécifiques visant à arrêter les hémorragies au plus tôt, le recours à l'acide tranexaminique, la prévention des hypothermies et l'application d'une politique raisonnée de rénaimation/chirurgie ont constitué une grande avancée. Certaines nations ont équipé leurs vecteurs d'évacuations de concentrés érythrocytaires. Le maintien d'une coagulation optimale est un enjeu majeur. Pour cela existe, entre autres, le plasma lyophilisé. Les forces armées israéliennes militent pour l'emploi de ce type de solutions en phase préhospitalière
Mise en condition de survie des blessés en opération extérieure : Procédure et expérience à partir du terrain afghan
Conditions for the survival of combat casualties in overseas operations : procedure and experience from the Afghan out-of-hospital theater
Les conﬂits récents ont amené le service de santé des armées français à préciser la mise en condition de survie des blessés de guerre en opération extérieure. La majorité d’entre eux est victime de blessures par explosion et un contrôle précoce de l’hémorragie est le moyen principal d’améliorer la survie. Une procédure appelée « Sauvetage au Combat » est enseignée pour la mise en condition de survie de ces blessés. Elle est appliquée depuis quelques années sur le terrain afghan.
Recent conﬂicts have led the French Army Health Service to specify the setting condition for the survival of combat casualties in overseas operations. The majority of them are victims of explosion injuries, and an early and effective control of bleeding is the primary means of improving survival. A procedure called ‘‘ Combat Rescue ’’ is taught. This chronological procedure favours external haemostasis and led to speciﬁc equipment, in particular a tourniquet and a haemostatic bandage of high efficiency. It is applied in recent years on the Afghan out-of-hospital theatre. A very front medical presence, which is systematic during evacuations, is a feature of the French Army Health Service operations support.
Army flight medic performance of paramedic level procedures: Indicated vs performed
Bier SA et all. - J Emerg Med. 2013 May;44(5):962-9.
Of 984 interventions found to be indicated on the 406 charts that met inclusion criteria, 36% were rated as EMT-P level. Seventeen percent were indicated but not performed. EMT-Bs failed to perform indicated procedures 35% of the time vs. 3% in the EMT-P group (p < 0.001). For paramedic-level procedures, EMTBs failed to make 76% of appropriate interventions, compared to <1% in the EMT-P group (p < 0.001). Conclusions: There seems to be a substantial number of procedures beyond the scope of standard Army flight medic training being required for Army AMT missions. It seems that when advance interventions are indicated, those trained to the EMT-P level perform them significantly more often than those trained to Army standard. Conclusions: Based on the findings of this study, the authors suggest the Army consider adopting the standards required for civilian AMT
