Evaluation de la prise en charge des cas graves de COVID-19 aux soins intensifs dans un environnement à ressources limitées: expérience du centre de traitement des épidemies (CTE) d'Allada / NA

Introduction : Dans sa politique de riposte contre la pandémie liée à l'infection au SARS-COV2, le Bénin a opté pour la construction d'Hôpitaux dédiés exclusivement à la prise en charge des COVID19. Pendant la première vague de la pandémie en Afrique, les systèmes de santé n'étaient pas encore bien outillés pour faire face à cette pandémie. Nous vous rapportons l'expérience des soins intensifs du Centre de traitement des épidémies (CTE) d'ALLADA. Objectifs : évaluer la prise en charges des cas graves de COVID19 à l'USI du CTE ALLADA. Matériels et méthode : Il s'est agi d'une étude prospective, descriptive et analytique, réalisée aux soins intensifs du centre de traitement des épidémies d'ALLADA, du 1er juin au 31 Août 2020. Résultats : Quatre-vingt-quatorze malades étaient éligibles pour notre étude. L'âge moyen des malades était de 58,41 ans, le sex-ratio 1,61. Les comorbidités les plus représentatives étaient l'hypertension artérielle (70,21%), le diabète (31,91%), l'obésité morbide (21,28%) et l'asthme (15,96%). Selon le score de gravité adopté au Bénin, trente-six malades (38,30%) étaient classés cas graves grade3 et ont bénéficié d'une ventilation mécanique. La VNI était la technique de ventilation la plus utilisée (75% des cas). Le plateau technique était limité et les ressources humaines qualifiées insuffisantes. Les associations chloroquine/azithromycine ou lopinavir/ritonavir/ribavirine étaient les traitements spécifiques utilisés. La mortalité était de 27,66%. Conclusion : Malgré les conditions de travail difficiles, notamment le plateau technique limité et les ressources humaines qualifiées insuffisantes, les résultats obtenus après traitement des cas graves de COVID19 à l'USI du CTE ALLADA étaient encourageants

Introduction: To respond to the pandemic linked to the SARS-COV-2 infection, Benin has opted for the construction of hospitals dedicated exclusively to the treatment of COVID-19. During the first wave of the pandemic in Africa, health systems were not yet well equipped to deal with this pandemic. We here report the Intensive CareUnit (ICU) experience of the Epidemic Treatment Center of ALLADA (ETCA). Purpose: To assess the management of serious cases of COVID-19 in the ICU of ETCA. Materials and method: This was a prospective, descriptive and analytical study, carried out in the ICU of ETCA, from June 1 to August 31, 2020. Results: Ninety-four patients were eligible for our study. The average age of the patients was 58.41 years with a sex ratio of 1.61. The most representative comorbidities were arterial hypertension (70.21%), diabetes (31.91%), morbid obesity (21.28%) and asthma (15.96%). According to the severity score adopted in Benin, thirty-six patients (38.30%) were classified as severe grade III cases and received mechanical ventilation. Non-Invasive Ventilation (NIV) was the most used ventilation technique (75% of cases). The technical platform was limited and the qualified human resources were insufficient. Chloroquine/azithromycin or lopinavir / ritonavir/ribavirine were the specific treatments used. Mortality was 27.66%. Conclusion: Despite the difficult working conditions, especially the limited technical platform and insufficient qualified human resources, the results obtained after treatment of serious cases of COVID-19 at the ICU of ETCA were encouraging

Detection of a Left Superior Vena Cava during a Pacemaker Implantation in Cotonou.

Persistent left superior vena cava (LSVC) is a rare congenital anomaly. Its prevalence in the general population is 0.1 to 0.5%. LSVC is 5 times rarer when accompanied by an absence of the right superior vena cava (RSVC). We present the case of a 54-year-old man who carries a persistent LSVC without RSVC. Clinically, this patient presented a regular bradycardia at 40 per minute associated with a heart failure syndrome. The electrocardiogram diagnosed a complete atrioventricular block and transthoracic echocardiography showed dilated left heart cavities and a left ventricular ejection fraction of 50%. During the procedure of pacemaker implantation, the probe followed an unusual LSVC-coronary sinus-right atrium path and it was not easy to pass through the tricuspid orifice. We propose a review of the literature on this subject, focusing on the clinical implications of this malformation in cardiac stimulation and in other areas of cardiology.

[Loss of capture by myocardial ischemia: A case report]. / Perte de capture par ischémie myocardique : à propos d'un cas.

We report the case of a patient with pacemaker who presented chest pain during exercise followed by fainting. He has a history of arterial hypertension and diabetes. The initial examination was normal; the ventricular stimulation threshold was 1.125 volts (V) and cardiac enzymes were normal. Stress test has reproduced chest pain followed by loss of pacemaker capture and asystole. Coronary angiography showed a tight stenosis of the proximal anterior interventricular artery dilated by a drug-eluting stent. The control of stress test was normal. A stent thrombosis eight days later led to an acute coronary syndrome with recurrent syncope due to the loss of ventricular capture. The ventricular pacing threshold was then 2.25V. After revascularization and stabilization of the patient's clinical status, this threshold returned to 1.125V. This clinic case has confirmed that coronary artery disease could increase pacing threshold. It also highlights the usefulness of automatic capture algorithms in coronary patients. The stress test cannot only help to detect coronary artery disease but also allows the optimization of programming the pacemaker.
