  • Article: [Jugular venous and arterial concentrations of serum S100B protein in patients with severe head injury].
    [show abstract] [hide abstract]
    ABSTRACT: It is important for physicians in intensive care units to be able to predict the presence and severity of central nervous system injury in patients with severe head injury (SHI). The extent of S100B elevation has been found to be useful in predicting clinical outcome after brain injury. However, only two studies were realized with jugular venous blood samples. The purpose of our study is to compare the interest between jugular venous and arterial concentrations evaluation of serum S100B protein in patients with SHI. We recruited 17 patients with a SHI, admitted to the intensive care unit. Paired arterial and jugular venous samples were taken at kinetically after injury. S100B median was 0.16 μg/L in arterial and 0.25 μg/L in jugular. This arterio-jugular difference is significant. However, there was any significant arterio-jugular difference in the patients group showing an unfavourable outcome or for the earlier samples (earlier than 24h). We observed there was no significant decrease of S100B in jugular, unlike in arterial, 24h after the head injury in the patients group showing an unfavourable outcome. Determination of S100B concentration in jugular samples appears to be better than in arterial to predict clinical outcome after brain injury.

  • Article: Combined nitric oxide inhalation, prone positioning and almitrine infusion improve oxygenation in severe ARDS
    [show abstract] [hide abstract]
    ABSTRACT: PurposeTo determine the efficacy and side effects of prone positioning (PP) and nitric oxide (NO) inhalation, alone, associated, or combined withiv almitrine for the treatment of hypoxaemia in severe acute respiratory distress syndrome (ARDS). MethodsOver a period of 20 months, 27 consecutive critically ill patients with severe ARDS (Murray score > 2.5, PaO2/FiO2 < 170 after alveolar recruitment) were prospectively and randomly included. They inhaled NO for two hours at concentrations of 5 and 10 ppm for one hour each (H0–H2). One hour later, they were returned to the prone position for four hours (H3–H7). During the last two hours in this position (H5–H7), they were assigned to further inhalation of 10 ppm NO (Group B, n = 9) or to no further inhalation (Group A, n = 9). In group C (n = 9), the procedure for group B was combined with perfusion of 16 mg · kg−1 · min−1 almitrine throughout the study. ResultsCompared with control values, two hours NO inhalation improves PaO2/FiO2 and shunt effect by +28% and −9%, PP by +88% and −27%, PP + almitrine by + 132% and −28%, NO + almitrine by + 153 and −28%, PP + NO by +94% and −29%, NO + PP + almitrine by +327 and −48%. NO inhalation reduces pulmonary vascular resistance. Other haemodynamic parameters remain unchanged, whatever the treatment. NO inhalation improves PaO2/FiO2 by over 20% in 50% of the patients and PP is effective in 78% of the cases. ConclusionProne Position improves PaO2/FiO2 significantly more than NO alone but less than PP+ almitrine or NO+ almitrine. The best results are obtained with the association of NO + Prone position + Almitrine. ObjectifApprécier et comparer l’intérêt du décubitus ventral (DV), de l’inhalation de NO et de l’administration continue d’almitrine, seuls ou en association, dans le traitement de l’hypoxémie au cours du syndrome de détresse respiratoire aiguë (SDRA). MéthodeSur une période de 20 mois, 27 patients hospitalisés en réanimation avec un SDRA grave (score de Murray > 2,5, PaO2/FiO2 < 170 après recrutement alvéolaire) ont été inclus prospectivement et de manière randomisée. Ils ont bénéficié de l’inhalation de NO pendant 2 heures à la posologie de 5ppm pendant une heure puis I0ppm (H0–H2). Après une heure d’arrêt, on les a retournés 4 heures en décubitus ventral (H3–H7). De H5 à H7 un groupe A (n = 9) était traité par DV seul tandis que l’on ajoutait dans un groupe B (n = 9) l’inhalation de NO à 10 ppm. Un troisième groupe C (n = 9) bénéficiait d’une perfusion continue d’almitrine (16 mg · kg−1 · min−1) associée à cette même séquence thérapeutique. RésultatsPar rapport à H0, 2 heures de NO améliorent le rapport PaO2/FiO2 et diminuent le shunt de +28% et −9%, le DV de +88% et −27%, les associations DV + almitrine de + 132% et −28%, NO + almitrine de +153 et −28%, DV + NO de +94% et −29%, NO + PP + almitrine de +327 et −48%. L’inhalation de NO diminue les resistances vasculaires pulmonaires. Les autres paramètres hémodynamiques restent inchangés quel que soit le traitement institué. L’inhalation de NO améliore le rapport PaO2/FiO2 de plus de 20% chez 50% des patients tandis qu’avec le même critère d’efficacité, 78% des malades sont répondeur au DV ConclusionLe DV s’avère plus efficace que le NO seul pour ce qui est d’améliorer le rapport PaO2/FiO2, mais moins que les associations DV + almitrine ou NO + almitrine. Les meilleurs résultats sont obtenus avec latrithérapie DV + NO + almitrine.
