Abstract
L’intubation trachéale (IT) est un geste fréquent en médecine d’urgence extra-hospitalière (MUEH) mais elle est associée à un taux élevé d’échec de la première tentative et à certaines complications graves. Le taux de ces dernières augmente avec le nombre de tentative d’IT. La Société française d’anesthésie et de réanimation (SFAR) et la Société de réanimation de langue française (SRLF) avec la collaboration de la Société française de médecine d’urgence (SFMU) ont publié en 2016 des recommandations formalisées d’experts (RFE) sur l’intubation du patient de réanimation. La question qui se pose est la pertinence de ces recommandations pour la MUEH. En effet, la mesure du risque de difficulté est basée sur le score de MACOCHA et en cas de difficulté prévue les outils à utiliser d’emblée sont le vidéo-laryngoscope ou le mandrin long béquillé en laryngoscopie directe. Or il apparait que le score de MACOCHA n’est pas adapté à la MUEH et de façon plus générale, il est complexe de mesurer le risque d’intubation difficile (ID) dans ce contexte. La vidéolaryngoscopie n’a pas encore fait la preuve de sa supériorité par rapport à la laryngoscopie directe en MUEH. Par contre des travaux récents en médecine d’urgence ont démontré que l’utilisation en première intention du mandrin long béquillé augmente significativement le taux de succès de la première tentative de l’IT, même en l’absence de facteur de risque d’ID. Au total, on pourrait considérer chaque IT en MUEH comme a priori à risque de difficulté ce qui justifierait une utilisation d’emblée du mandrin long béquillé. Il semble nécessaire de proposer des recommandations spécifiques à la médecine d’urgence.

Abstract
OBJECTIVES In France, medical students regularly complain about the shortcomings of their theoretical training and the necessity of its adaptation to better fit the needs of students. The goal was to evaluate the theoretical teaching practices in postgraduate medical studies by: 1) collecting data from medical students in different medical faculties in France; 2) comparing this data with expected practices when it is possible; 3) and proposing several lines of improvement. METHODS A survey of theoretical practices in the 3rd cycle of medical studies was conducted by self-administered questionnaires which were free of charge, anonymous, and administered electronically from July 3 to October 31, 2013 to all medical students in France. RESULTS National, inter-regional, regional and field internship educational content was absent in respectively 50.5%, 42.8%, 26.0% and 30.2% of cases. Medical students follow complementary training due to insufficient DES and/or DESC 2 training in 43.7% of cases or as part of a professional project in 54.9% of cases. The knowledge sought by medical students concerns the following crosscutting topics: career development (58.9%), practice management (50.7%), medical English (50.4%) and their specialty organization (49.9%). Fifty-four point one percent would like to be evaluated on their theoretical training on an annual basis. CONCLUSION The results of this first national survey give insights into the theoretical teaching conditions in postgraduate medical education in France and the aspirations of medical students.

Abstract
OBJECTIVES As far as the reform of the "Diplômes d'études spécialisées" (DES) is approaching, a first national evaluation of the Medical Gynecology diploma was necessary. The objective was to evaluate the practices of the theoretical teaching with the whole students, by receiving their opinions and their wishes of changing, and by proposing some improving measures. PATIENTS AND METHODS The self-evaluation form made by members of the Association of residents (AIGM) and the Teacher's College (CNEGM) was submitted to the students during the national teaching session of June 2014. RESULTS Fifty-six results were gathered among 145 students enrolled at the DES (38.6 %). Twelve half days of national theoretical training are yearly scheduled. The accordance of the national theoretical training to the level of the students was assessed on average at 7.8 (VAS from 0 to 10). The scientific and pedagogical skills of the speakers are evaluated at 8.9 and 7.8. The theoretical training of the diploma was considered as satisfying for 76.6 % of the respondents. DISCUSSION AND CONCLUSION Despite a globally satisfying evaluation, some points can be improved in the organization of the diploma. The introduction of courses about establishment, medical acts and imaging, the implementation of gradual progress teaching, the development of hands-on training and practical works, reciprocal evaluation of the students and the teachings/teachers, should be set up.

Abstract
This prospective study was conducted to describe the signs on transesophageal echocardiography (TEE) associated with traumatic aortic injury (TAI). Twenty-eight patients with TAI underwent TEE, and they were compared with a control group of 30 thoracic trauma patients without aortic injury. The TEE signs were classified as direct or indirect signs, and the quality of imaging was assessed. Patients' TEE images were compared with their anatomic lesions. The direct signs were thick stripes (n=19), false aneurysm (n=7), aortic dissection (n=6), free-edge intimal flap (n=15), aortic wall hematoma (n=2), fusiform aneurysm (n=13), and complete aortic obstruction (n=2). The indirect signs included minor increases in aortic diameter (n=7), impairment of the aortic Doppler color flow (n= 18), and an increase of aorta-probe distance, indicating hemomediastinum (n=23). TEE allowed diagnosis of recently described limited intimal lesions frequently missed by other conventional methods, and permitted rapid diagnosis of complete rupture in which fast degeneration means that more time-consuming methods are not practicable. Significant blurring of the aortic outline was noted in 20% of cases and intraluminal artifacts were observed in 36% of cases, but neither sign impaired accurate diagnosis of TAI. The echocardiographic signs of aortic injury are complex and may be confined to a short section of the aorta. Therefore, examination by a physician highly trained in echocardiography is necessary in such cases.

Abstract
BACKGROUND Left ventricular fractional area changes (FAC) can be derived from transesophageal echocardiography using an automated border detection system. However, FAC has not yet been compared to left ventricular ejection fraction (EF) evaluated by a reference technique. The aim of this study was to correlate transesophageal echocardiography automated FAC to EF derived from radionuclide angiography to obtain a quantifying method of global left ventricular systolic function at the bedside. METHODS Ten critically ill patients, whose lungs were mechanically ventilated, were included in this prospective study. Patients were scheduled for radionuclide EF evaluation when at least 75% of the endocardium was clearly visualized on transesophageal echocardiography. Patients with esophageal pathology or cardiac dysrhythmia were excluded. Ejection fraction derived from radionuclide angiography was measured using technetium 99m. Echocardiographic data were obtained using an ultrasound system with automated border capabilities. Simultaneous measurements of left ventricular EF and FAC were obtained for each patient, both before and after starting a dobutamine intravenous infusion to modify left ventricular contractility. RESULTS Mean values for radionuclide EF and transesophageal echocardiography FAC were, respectively: 55% +/- 19% (range 19-89%) and 46% +/- 18% (range 17-80%). Left ventricular EF and FAC were significantly correlated (r = 0.85, SEE = 9.6%). Variations of EF and FAC, induced by dobutamine, were also correlated (r = 0.70, SEE = 4.9%). CONCLUSIONS Fractional area changes determined by transesophageal echocardiography using automated border detection correlate well with radionuclide EF and may be used at the bedside to quantify left ventricular function in selected intensive care unit patients.

Abstract
OBJECTIVE To assess if two different forms of upper airway topical anaesthesia induce similar changes in airway flow resistance (Rrs). DESIGN Serial measurements of Rrs before and after topical anaesthesia with acqueous or paste lidocaine. SETTING Lung function test laboratory. PARTICIPANTS 9 normal men with documented normal lung function tests. INTERVENTIONS 2 different session of topical upper airway anaesthesia with 100 mg of liquid 5% lidocaine and 100 mg of 2% lidocaine paste, respectively. MEASUREMENTS AND RESULTS Rrs was measured by the random noise forced oscillation technique. Fiberoptic upper airway examination was performed in two subjects. Rrs increased on average by 81% after lidocaine spray and by 68% after lidocaine paste (p < 0.005, respectively) with no difference in the magnitude of Rrs increase between the two modes of anaesthesia studied. This increase lasted 13 +/- 3 min (spray) and 12 +/- 3 min (paste), respectively (p = ns). Fiberoptic examination of the two most responders showed inspiratory laryngeal collapse. CONCLUSIONS Topical upper airway anaesthesia transiently increases Rrs with no specific effects regarding the drug presentation. Laryngeal dysfunction may be one mechanisms involved in Rrs increase following upper airway topical anaesthesia. Such findings may explain some poor respiratory tolerance reported during endoscopy.

Abstract
The effects of a pure benzodiazepine antagonist (Flumazenil) on the responses R1 and R2 of the blink reflex, psychomotor tests, and Event Related Potentials (ERP), in six healthy volunteers sedated with Midazolam have been compared. Measurements were made during each of four successive phases. Phase 0 corresponded to control recordings. Midazolam was administered rapidly during phase 1 and slowly during phase 2. Phase 3 corresponded to spontaneous waking once the administration of Midazolam had been stopped. Flumazenil was administered during phase 2. As the subjects fell asleep, R1 and R2 were the last parameters to disappear. Under the influence of Flumazenil, R1 was the first to reappear, while R2 did not recur until complete waking, and the other tests were unpracticable. During phase 3, R1 reappeared before R2 once more, the psychomotor test responses and ERP returning only later. The modifications of both R1 and R2 of the blink reflex are a good criterion of the presence of BZD in a toxic coma and a good test to indicate the depth of a coma or a sedation with BZD, whilst ERP, since they require the cooperation of the patient, are a test of vigilance and not of awakening.

Abstract
A prospective study assessing the interest in and the results of systematic transesophageal echocardiography (TEE) examination in nonselected intubated multiple injury patients was carried out from January 1992 through June 1993. Seventy patients were included and divided into two groups according to the results of admission screening, including clinical examination, EKG, CK-MB and chest radiograph. Group 1 (60 patients) had abnormalities on initial screening, while group 2 (10 patients) had no symptom of thoracic or mediastinal injury. TEE was performed within 48 hours following admission and its results were compared with those of the initial screening. TEE usefulness was evaluated on a score grade from 0 (no interest) to 4 (outstanding interest). Myocardial contusion was suspected in 25 patients. TEE invalidated 18 suspected and found 5 unsuspected myocardial contusions. Pericardial effusion was suspected in only one case, while TEE documented 13 additional cases. A mediastinal enlargement was seen in 13 patients, but TEE invalidated aortic lesions in all these cases and made an unsuspected diagnosis of aortic tears. Eight cases of severe hypovolemia and seven cases of left ventricle dysfunction were detected by TEE. The score of interest showed that TEE allowed new interesting diagnoses in 70% of group I patients and in 33% of group II patients. TEE is of utmost importance in multiple injury patients, with or without any evidence of thoracic or mediastinal injury, providing a safe and rapid examination of the mediastinal structures and an evaluation of the hemodynamic status.

Abstract
The effects of apnea testing-induced respiratory acidosis on left ventricular function (LVF) are still controversial. The aim of the study was to assess LVF during apnea testing using transesophageal echocardiography (TEE). Twenty consecutive patients suspected of brain death, hemodynamically stable, and considered as potential organ donors were prospectively studied. A 20-min apnea test was performed after obtaining a PaCO2 > 35 mmHg and 20 min of FIO2 1 ventilation. LVF was assessed using TEE with a CFM 750 (Diasonic) connected to a 5 MHz probe. Heart rate (HR), mean arterial pressure (MAP), left ventricle end-diastolic and systolic area (LVEDA, LVESA), and LVF assessed by fractional area changes (FAC), systolic wall motion (SWM) scores, and blood gases were recorded at baseline, and after 5, 10, 15, and 20 min of apnea testing. In 19 patients, no spontaneous respiratory movement occurred during the standard 20-min period. In one patient (No. 15), the apnea test had to be stopped after 10 min because of hypoxia. HR, LVEDA, LVESA, and SWM were not significantly modified during the study. There was a progressive statistically significant decrease in MAP during apnea (from 77 +/- 10 to 63 +/- 11 mmHg), associated with a statistically significant increase in FAC at 20 min (from 48 +/- 13 to 56 +/- 8%). PaCO2 progressively rose (from 40 +/- 3 to 95 +/- 11 mmHg), associated with a decrease in pH (from 7.42 +/- 0.06 to 7.09 +/- 0.08). At the same time, PaO2 decreased slightly in all patients, but values remained well above hypoxic levels, except for one patient. Despite severe respiratory acidosis the increase in FAC suggests that apnea testing is well tolerated for brain death assessment.

Abstract
Pain is a major factor of respiratory decompensation after chest trauma. General and/or regional analgesia improve alveolar ventilation, make physiotherapy easier and often avoid mechanical ventilation. Concerning regional techniques, epidural, intercostal and interpleural routes have their respective indications and contraindications, benefits and risks. When suitable, epidural analgesia appears to be the preferable technique.

Abstract
BACKGROUND Clonidine stops postoperative shivering, but its underlying mechanism of action is unknown. Clonidine may impair central control of thermoregulation or act on peripheral receptors. Accordingly, the authors tested the hypothesis that clonidine reduces both the vasoconstriction and shivering thresholds, a pattern consistent with central thermoregulatory impairment. METHODS Seven healthy volunteers participated in the study. Thermoregulatory vasoconstriction was evaluated using forearm minus fingertip, skin-temperature gradients; values exceeding 4 degrees C were considered to be significant vasoconstriction. Systemic oxygen consumption (VO2) was measured with a canopy system. In addition, shivering was qualitatively evaluated using a simple scale, graduated from 0 (no shivering) to 2 (intense shivering). The tympanic membrane temperatures triggering significant vasoconstriction and grade 1 shivering were considered to be the thresholds for the two thermoregulatory responses. Measurements were performed after a 10-min steady state period and during cooling by central venous infusion of Ringer's lactate solution at 4 degrees C. Each subject was evaluated at two sessions, separated by at least 48 h. They were randomly and blindly assigned to received either an intravenous bolus of 75 micrograms clonidine or a placebo before cooling. When the shivering score equaled 2, 75 micrograms clonidine was injected intravenously, and repeated if necessary, to completely stop shivering.

Abstract
The benefits of transoesophageal echocardiography (TOE) were assessed prospectively in intensive care patients. The doctors carrying out TOE were not the same as those who ordered it. TOE was performed in 32 patients, all of whom but one were intubated and artificially ventilated, to elucidate the cause of circulatory shock, or to search for valvular vegetations or an intracardiac mass. TOE confirmed the diagnosis previously obtained with pulmonary arterial catheterization (10 patients), transthoracic echocardiography (3 patients) or ventriculography (1 patient) in 54% of cases. In 28% of cases, TOE invalidated the suspected diagnosis, and, in the remaining 28% of patients, TOE invalidated provided a previously unsuspected diagnosis. TOE was particularly useful in confirming the presence of valvular vegetations, endocarditis, or intracardiac thrombi, and to assess left ventricular function and preload in patients in shock. Like others, this study confirms the benefits of TOE in the intensive care setting.

Abstract
Preoperative normovolemic hemodilution (PNH) has been proposed for patients scheduled to undergo aortic surgery. Coronary artery disease is frequent in these patients. The aim of the study was to assess the effect of PNH on hemodynamics and segmental wall motion (SWM) evaluated by transesophageal echocardiography in such patients. Twenty patients with coronary artery disease were allocated randomly to either PNH or no PNH; PNH was performed after anesthetic induction using dextran 60,000. Patients were operated on under general anesthesia and monitored intraoperatively with electrocardiographic lead CM5, radial and pulmonary artery catheters, and transesophageal echocardiography positioned to obtain a short-axis view. Hemodynamic and transesophageal echocardiographic data were collected after anesthetic induction and after PNH, before and 5 min after aortic clamping, after unclamping, and at the end of surgery. Aortic clamping induced a significant increase in systemic vascular resistance and arteriovenous difference in oxygen and a decrease in cardiac index (P < 0.05), but the effect of aortic clamping was inversely related to hemodilution. The SWM score (graded from 1 = normal to 5 = dyskinesia) was significantly increased after aortic clamping, mainly in the anterior segment (P < 0.05). Four patients in the control (no PNH) group and one in the PNH group developed new SWM abnormalities indicative of myocardial ischemia during surgery (P = NS). This study suggests that PNH may improve hemodynamic tolerance to aortic clamping in patients with coronary artery disease. The observed changes in SWM indicate that PNH may not worsen myocardial ischemia in patients scheduled to undergo aortic surgery.

Abstract
Patients scheduled for vascular surgery are considered at risk for perioperative cardiac complications. Choice of anesthetic in such patients is guided by a desire not to adversely affect myocardial function. On the basis of data from laboratory studies, thoracic epidural anesthesia (TEA) has been advocated to prevent myocardial ischemia. The aim of this study was to assess whether TEA combined with general anesthesia has any effect on segmental wall motion (SWM) monitored by transesophageal echocardiography in these patients. Patients received alfentanil, midazolam, vecuronium, and 50% N2O in oxygen, and ventilation was controlled after orotracheal intubation; 12.5 mL of 2% lidocaine HCl was injected through an epidural catheter placed at T6-7 or T7-8. Hemodynamic measurements and transesophageal echocardiographic recordings were obtained before and 10, 20, 30, 40, and 60 min after lidocaine injection. Segmental wall motion was graded a posteriori by two independent experts on a predetermined scale (from 1 = normal to 5 = dyskinesia). A decrease greater than or equal to 2 grades was considered an SWM abnormality indicative of ischemia. Thoracic epidural anesthesia induced a decrease in systemic arterial blood pressure, heart rate, and cardiac index. The SWM score decreased slightly from 1.34 +/- 0.68 to 1.27 +/- 0.64 (mean +/- SD) (at 10 and 20 min, respectively) (P less than 0.05). Patients were a posteriori analyzed according to whether they had documented coronary artery disease or not. The SWM score before TEA was significantly higher in patients with documented coronary artery disease (1.51 +/- 0.88 vs 1.17 +/- 0.51, respectively; P less than 0.05) and did not change significantly after TEA.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
A case is reported of a patient with a traumatic aneurysm of the intracranial part of the carotid artery occurring after a traffic accident. The patient was admitted in coma (Glasgow score 5), and presented with a depressed fracture of the frontal and parietal bones, a fracture of the left petrous pyramid and of the left anterior clinoid process, as well as of the right tympanic bone and temporomandibular joint. The borders of the left carotid canal seemed unaltered. Despite the lack of localised neurological signs, cervical and transcranial Doppler ultrasonography was carried out. Intracranial carotid blood flow was found to be altered on both sides. Angiography showed a false carotid aneurysm on the left side (carotid siphon portion C3), and a moderate irregular stenosis of the C2 part on the right. There were no brain lesions on the CT scan. Prophylactic treatment with heparin was started. The patient recovered normal consciousness within a fortnight. The false aneurysm increased in volume and was treated by embolisation. Flow speeds in the carotid siphons also returned to normal. The usefulness of routine screening of patients with petrous bone fractures with Doppler ultrasound is discussed.

Abstract
The effect of oral premedication with 300 micrograms of clonidine on systemic arterial pressure, heart rate, and plasma norepinephrine levels was assessed in a double-blinded, placebo-controlled study conducted in 29 patients subjected to carotid artery surgery (CAS). Anesthesia was induced with thiopental, 6 mg/kg, and alfentanil, 0.05 mg/kg, and maintained with alfentanil and 0.6% isoflurane in 50% N20/O2. The study was divided into five periods as follows: (1) anesthesia to start of surgery; (2) surgery to carotid artery clamping; (3) carotid artery clamping to unclamping; (4) carotid artery unclamping to the end of surgery; and (5) the first 4 postoperative hours in the recovery room. In the clonidine group (n = 14), plasma norepinephrine concentrations were significantly lower before induction of anesthesia and during the operative period. Heart rate and systemic arterial pressure were lower (P less than 0.01) in the clonidine group at 3 different time intervals (control, carotid clamping, carotid unclamping). However, during each of the previously defined periods, the variability of heart rate and systemic arterial pressure, assessed by the coefficient of variation, was not different between the two groups. The lability of these hemodynamic parameters, expressed as the percentage of values, which increased or decreased more than 20% of control values during the corresponding period, was also comparable between the two groups. The number of patients who experienced at least one episode of hypertension (systolic arterial pressure greater than 180 mm Hg), hypotension (systolic arterial pressure less than 100 mm Hg), or bradycardia less than 45 beats/min was not different between the two groups.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
This study was designed to determine whether clonidine has analgesic properties, decreases the minimum alveolar concentration of inhalational anesthetics, or affects the quality and the duration of spinal anesthesia with bupivacaine. The comparative effects of oral and subarachnoid clonidine on spinal anesthesia with bupivacaine were studied in 36 patients scheduled for orthopedic surgery. Patients were allocated randomly into four groups to receive either oral diazepam (10 mg in Groups I and II) or oral clonidine (150 micrograms and 300 micrograms in Groups III and IV, respectively), as premedication. Spinal anesthesia was performed with 15 mg hyperbaric bupivacaine 0.5% plus either 1 ml isotonic saline in Groups I, III, and IV, or 150 micrograms clonidine in Group II. Subarachnoid but not oral clonidine significantly prolonged the duration of sensory block (time for regression to L2 was 157 +/- 21 minutes in Group I and 267 +/- 75 minutes in Group II) and the duration of motor block (duration of Grade 3 motor block--Bromage scale--was 103 +/- 20 minutes in Group I and 175 +/- 68 minutes in Group II). Only the subarachnoid administration of clonidine achieves adequate concentrations to significantly increase the duration of spinal anesthesia.

Abstract
A case is reported of a foramen ovale becoming patent during orthotopic liver transplantation (OLT). The patient had a hepatoma secondary to post-hepatitis cirrhosis. Monitoring included transesophageal echocardiography (TEE). A veno-venous shunt between the right femoral, portal and left axillary veins was used so as to maintain the venous return during portal and caval clamping. The patient's haemodynamic state remained quite stable throughout this period, and no vasoactive drug was required. Five min after graft reperfusion, pulmonary arterial pressure increased suddenly (mean PAP: 27 mmHg). TEE revealed paradoxical movements of the atrial septum. Colour coded Doppler ultrasound showed blood flowing from the right to the left atrium through a patent foramen ovale. Fifteen min later, mean PAP decreased (18 mmHg) and TEE no longer showed any flow between the two atria. Several studies have reported transient pulmonary hypertension after unclamping when the donor liver is reperfused. This could induce right ventricular failure, with transient inversion of the atrial pressure gradient, which, in turn, could result in a right-to-left shunt through a patent foramen ovale. TEE can monitor regional and overall left ventricular function as well as the atrial septum. This technique might therefore to be useful for cardiac monitoring during OLT.

Abstract
A 56-year-old woman was admitted to the Emergency Department for profuse diarrhoea, associated with hypokaliemia and dehydration. A subclavian venous catheter was inserted after she had a cardiac arrest. Six days later, the subclavian and innominate veins were thrombosed. Prophylactic low molecular weight heparin was then replaced by sodium heparinate. The patient's platelet count decreased to 65 G.1-1. It was nevertheless decided to remove her villous tumour. After the operation, the patient became shocked, with worsening thrombocytopaenia (15 G.1-1). She was unresponsive to fluid replacement. Transoesophageal echocardiography (TEE) was carried out, as pulmonary arterial catheterization was considered too dangerous. A "white" thromboembolus was discovered in the right pulmonary artery. Embolectomy was successfully performed without extracorporeal circulation. Flow was completely restored in the main pulmonary artery, but only partially in the right branch. Oral anticoagulation was started postoperatively. It is concluded that TEE might be a very helpful technique to promptly diagnose acute pulmonary embolism; moreover, it could be an alternative to pulmonary angiography, especially in patients in a poor state.
