ABSTRACT

INTRODUCTION: In the French army, combat casualty care (CCC) training involves the use of simulation. The application of this pedagogic method in a cross-cultural environment has not previously been described. In this report, we explore the challenges highlighted by multiple training sessions for foreign medical providers in West Africa. METHODS: We collected the data from six 2-week courses held in Libreville, Gabon. Our main objective was to describe the course; our secondary objective was to assess our trainees' progress in their knowledge of CCC. RESULTS: The first week involved lectures, technical workshops, and single-patient simulations. The second part emphasized multiple-victim simulations and interactions with combatants and was held in the Gabonese rainforest. Sixty- two trainees undertook the six sessions. Their knowledge improved during the course, from a median score of 4 (of a maximum of 40) before to 9.5 after (p < .05). DISCUSSION: Our study is the first to describe medical-level CCC training in a cross-cultural environment. Challenges are numerous, notably differences in the expected roles of instructors and trainees. Mitigating those difficulties is possible through cultural awareness and self-awareness. Our results are limited by the absence of evaluation of improvement in the actual management of patients. CONCLUSION: CCC training using medical simulation is feasible in a cross-cultural environment.

ABSTRACT

To determine whether a beat-by-beat cardiovascular index (CARDEAN: cardiovascular depth of analgesia, Alpha-2 Ltd, Lyon, France) reduces the incidence of tachycardia in ASA I-III patients undergoing orthopaedic surgery. A total of 76 patients were prospectively randomized into (1) a control group or (2) the CARDEAN group, in which the nurse anaesthetist was blinded to CARDEAN application. In addition to conventional signs, an external observer instructed the nurse anaesthetist to administer sufentanil 0.1 µg kg-1 when the CARDEAN crossed a threshold (≥ 60). The primary outcome was the incidence of tachycardia (> 120% of reference heart rate, HR). Non-invasive blood pressure (BP), electrocardiogram (ECG), O2 saturation-photoplethysmography and the bispectral index (40 < BIS < 60) were monitored. HR and an estimation of beat-by-beat BP changes acquired from photoplethysmography and ECG were combined in an algorithm that detected hypertension followed by tachycardia (index scaled 0-100). Sufentanil 0.1 µg kg-1 was administered when tachycardia, hypertension or movement ("conventional signs") was observed. Data for 66 patients (27 with known hypertension) were analysed. In the CARDEAN group, (a) the dose of sufentanil was higher (control: 0.46 µg kg-1 100 min-1, CARDEAN: 0.57 µg kg-1 100 min-1, p = 0.016), (b) the incidence rates of tachycardia and untoward events were lower (respectively: - 44%; control: 2.52 events 100 min-1 [1.98-3.22]; CARDEAN: 1.42 [1.03-1.96], p = 0.005, hazard ratio: 0.56; movement, muscular contraction, or coughing: control: 0.74 events 100 min-1 [0.47-1.16]; CARDEAN: 0.31 [0.15-0.62], p = 0.038), and (c) extubation occurred more often in the operating room (control: 76.5%, CARDEAN: 97%, p = 0.016). CARDEAN-titrated opioid administration was associated with a higher dose of sufentanil, a reduction in tachycardia and earlier emergence in ASA I-III patients undergoing major orthopaedic surgery.

ABSTRACT

INTRODUCTION: Depending on their theatre of operation, French soldiers may potentially be exposed to scorpion stings and snakebites. Following the recommendations of a French military health service (FMHS) technical committee for envenomation, the FMHS provides antivenoms appropriate to each deployment. This work aimed to evaluate this risk of envenomation and to assess the antivenoms used by the FMHS in operational theatres since the creation of this committee in 2015. METHODS: Cases were identified based on a review of temporary authorization of use application forms for the use of antivenom. Data were collected retrospectively from these forms, and prescribing physicians were contacted for any missing data. RESULTS: Between 2015 and 2017, 28 requests for temporary authorization of use were identified: 19 for Scorpifav (Sanofi-Pasteur, Lyon, France) and 9 for Fav-Afrique (Sanofi-Pasteur). The FMHS treated 15 soldiers and 4 civilians for scorpion envenomation with Scorpifav: 15 in Mali, 3 in Chad, and 1 in Niger. Systemic signs were observed in 7 patients. Two soldiers and 7 civilians were treated with Fav-Afrique for ophidian envenomation: 5 in Djibouti, 3 in Mali, and 1 in the Republic of Côte d'Ivoire. These 28 patients were treated without sequelae. Other than moderate erythema that resolved with an antihistamine, no adverse effects were reported. Medical evacuation to France was unnecessary. CONCLUSIONS: This study shows that the risk of envenomation for soldiers on deployment is low but real. Antivenoms used by the FMHS were efficient and well tolerated, preserving the operational capacity of deployed troops.

ABSTRACT

OBJECTIVE: Systemic capillary-leak syndrome is a very rare cause of recurrent hypovolemic shock. Few data are available on its clinical manifestations, laboratory findings, and outcomes of those patients requiring ICU admission. This study was undertaken to describe the clinical pictures and ICU management of severe systemic capillary-leak syndrome episodes. DESIGN, SETTING, PATIENTS: This multicenter retrospective analysis concerned patients entered in the European Clarkson's disease (EurêClark) Registry and admitted to ICUs between May 1992 and February 2016. MEASUREMENTS AND MAIN RESULTS: Fifty-nine attacks occurring in 37 patients (male-to-female sex ratio, 1.05; mean ± SD age, 51 ± 11.4 yr) were included. Among 34 patients (91.9%) with monoclonal immunoglobulin G gammopathy, 20 (58.8%) had kappa light chains. ICU-admission hemoglobin and proteinemia were respectively median (interquartile range) 20.2 g/dL (17.9-22 g/dL) and 50 g/L (36.5-58.5 g/L). IV immunoglobulins were infused (IV immunoglobulin) during 15 episodes (25.4%). A compartment syndrome developed during 12 episodes (20.3%). Eleven (18.6%) in-ICU deaths occurred. Bivariable analyses (the 37 patients' last episodes) retained Sequential Organ-Failure Assessment score greater than 10 (odds ratio, 12.9 [95% CI, 1.2-140]; p = 0.04) and cumulated fluid-therapy volume greater than 10.7 L (odds ratio, 16.8 [1.6-180]; p = 0.02) as independent predictors of hospital mortality. CONCLUSIONS: We described the largest cohort of severe systemic capillary-leak syndrome flares requiring ICU admission. High-volume fluid therapy was independently associated with poorer outcomes. IV immunoglobulin use was not associated with improved survival; hence, their use should be considered prudently and needs further evaluation in future studies.

ABSTRACT

INTRODUCTION: To improve the mortality rate on the battlefield, and especially the potentially survivable pre-Medical Treatment Facility deaths, Tactical Combat Casualty Care (TCCC) is now considered as a reference for management of combat casualty from the point of injury to the first medical treatment facility. TCCC comprises of a set of trauma management guidelines designed for use on the battlefield. The French Military Health Service also standardised a dedicated training programme, entitled "Sauvetage au Combat" (SC) ("forward combat casualty care"), with the characteristic of forward medicalisation on the battlefield, the medical team being projected as close as possible to the casualty at the point of injury. The aim of our article is to describe the process and the result of the SC training. MATERIALS AND METHODS: Records from the French Military Health Service Academy - École du Val-de-Grâce administration, head of the SC teaching programme, defining its guidelines, and supporting its structure and its execution, were examined and analyzed, since the standardisation of the SC training programme in 2008. The total number of trainees was listed following the different courses (SC1, SC2, SC3). RESULTS: At the end of 2013, every deployed combatant underwent SC1 courses (confidential data), 785 health-qualified combatants were graduated for SC2 courses and 672 Role 1 physician-nurse pairs for SC3 courses. CONCLUSION: The SC concept and programmes were defined in France in 2007 and are now completely integrated into the predeployment training of all combatants but also of French Military Health Service providers. Finally, SC teaching programmes enhance the importance of teamwork in forward combat medicalisation settings.

ABSTRACT

INTRODUCTION: The main goal of the North Atlantic Treaty Organization role 3 hospital located in Kabul is to provide comprehensive medical services to troops engaged in Afghanistan. Nevertheless, it also provides care for Afghan National Security Forces and for Afghan and non-Afghan civilians. OBJECTIVES: To describe the patients admitted to the conventional hospitalization unit over a 3-month period, between June 29 and October 1, 2012. RESULTS: A total of 439 patients were admitted, for scheduled surgery, discharged from intensive care unit, or referred by emergency room and primary care physicians. Causes of hospitalization were diverse, particularly for nonscheduled admissions, with mainly war- and traffic-accident-related injuries for Afghan civilians and national security forces, and non-war- and non-traffic-accident-related trauma emergencies and gastroenteritis for non-Afghan patients. Suspected or confirmed cardiovascular diseases were a frequent cause of hospitalization and the leading cause of medical evacuation out of war zone for non-Afghan civilians. The patients admitted for war injuries were mainly Afghan civilians, of whom 36.6% were children and 44.7% had been injured by improvised explosive devices. CONCLUSION: Reasons of admission to the conventional hospitalization unit were numerous. Care provided to Afghan and non-Afghan civilians represented the main activity of this unit.

ABSTRACT

This work provides a graphic description of the time course of hemostasis tests results during spontaneous evolution of Echis envenoming and correction of hemostasis disorders with antivenom therapy. The dynamics of fibrinogenemia (g L(-1)), prothrombin time (PT, %), activated partial thromboplastin time (aPTT, patient/normal ratio) and platelet count (Giga L(-1)) were collected from coagulopathic envenomed patients of a 12 years prospective study in Africa. Sixty patients were included. 47 of them (78%) received an antivenom (33 ± 12 ml) and 13 did not. Thirty patients (50%) presented bleeding. Only one patient died. The time for fibrinogen to be more than 1 g L(-1) was 181 ± 116 h (7.5 days) in the spontaneous evolution group versus 40 ± 21 h in the antivenom group (p < 0.0001). The times for reaching a PT above 50% were 140 ± 64 min (5.8 days) versus 25 ± 15 h (p < 0.00001) and for reaching an aPTT less than 1.5 times the normal values, 116 ± 76 h (4.7 days) versus 10 ± 9 h respectively (p < 0.0002). Thrombopenia was not a common feature of Echis envenomation. This study is the first one to provide a chart of the evolution of the hemostatic tests during envenomation caused by Echis bites. The plots enable to estimate that, in Echis envenomation, in the absence of antivenom administration, hemostasis remains severely affected until the 8-10th day of evolution. On the contrary, efficient antivenom against African vipers corrects clotting functions within a few hours.

ABSTRACT

BACKGROUND: Viperidae bites represent a public health issue in Africa and are responsible for a hemorrhagic syndrome with fatal outcome in the short term. A research on Medline database does not reveal any data definitively demonstrating the efficiency of antivenom in case of delayed administration. The aim of this study, based on a 12-year survey of viperine syndromes in Republic of Djibouti, was to compare the normalization of the hemostasis disorders with an early administration of antivenin versus a delayed administration. METHODS: A retrospective study was conducted from October 1994 to May 2006 in the intensive care unit of the French military Hospital, in Djibouti. Seventy-three Viperidae-envenomed patients were included. Antivenin efficiency in correcting hemostatic disorders was analyzed in relation to time to treatment (before or after the 24th hour after the bite). RESULTS: Forty-two patients (58%) presented with bleeding. A consumptive coagulopathy was found in 68 patients (93%). Antivenin was observed to be effective in improving hemostasis, and the time to normalization of biologic parameters was similar, whether the treatment was started before or after the 24th hour after the bite. CONCLUSION: Antivenin should ideally be administered as early as possible. However, in Africa, time to treatment generally exceeds 24 hours. The results of the present evidence-based study confirm an empirical concept: a delayed time to treatment should in no way counterindicate the use of antivenin immunotherapy, in the case of African Viperidae bites.

ABSTRACT

BACKGROUND: We sought to determine whether online use of a beat-by-beat cardiovascular index, CARDEAN (Alpha-2, Lyon, France), modifies the incidence of patient movement during colonoscopy under anesthesia. METHODS: Monitoring included an electrocardiogram, oscillometric and noninvasive beat-by-beat arterial blood pressure, O2 saturation, bispectral index (BIS), and CARDEAN. CARDEAN consists of beat-by-beat Finapres (Ohmeda, Madison, WI) combined with an algorithm that detects hypertension followed by tachycardia and produces an index scaled 0 to 100. The anesthesiologist was denied access to Finapres and CARDEAN. Propofol was adjusted to keep 4060. The primary outcome was the number of observed movements. RESULTS: Data were analyzed in 146 patients (control: 75; CARDEAN: 71). The doses of propofol and alfentanil were similar in both groups. When BIS was <60, movements were less frequent in the CARDEAN group (3.3 movements/100 min [2.3-4.8]) than in the control group (6.7 [5.3-8.5]) (odds ratio: 0.5 [0.32; 0.76], P = 0.001). During the first 10 minutes of the procedure, the incidence of movements was 38% and 59% in the CARDEAN and control groups, respectively (P = 0.04). CONCLUSION: With BIS <60, CARDEAN-guided opioid administration is associated with a reduction of 51% of clinically unpredictable movements in unparalyzed patients undergoing colonoscopy. More studies are required to refine the role of CARDEAN in surgical settings.

ABSTRACT

Tetanus is endemic in many developing countries. Although propofol has been proposed for sedation in tetanus, the routine use of this drug has not been clearly documented in published reports. A few studies have reported its beneficial effects but no randomized studies are available. We describe the case of a five-year-old boy who presented with severe tetanus in East Africa. The antispastic therapy consisted of benzodiazepine infusion with the addition of titrated boluses of propofol. Intubation and mechanical ventilation were avoided.
