Filter by:A decreased level of consciousness is a common reason for presentation to the emergency department (ED) and is often the result of intoxication (up to 1% of all ED visits and 3% of ICU admission). In France, approximately 165 000 poisoned patients are managed each year. Originally developed in head injured patients, the Glasgow Coma Scale (GCS) is a validated reproducible score evaluating the level of consciousness: a GCS ≤ 8 is strongly associated with reduced gag reflex and increased incidence of aspiration pneumonia. Although recommended for patients with traumatic brain injury and coma, it remains unknown whether the benefit of an invasive management of airways with sedation, intubation and mechanical ventilation should be applied to other causes of coma in particular for acute poisoned patients. The investigator hypothesize that a conservative management with close monitoring without immediate endotracheal intubation of these patients is effective and associated with less in-hospital complications (truncated at 28 days) compared to routine practice management (in which the decision of immediate intubation is left to the discretion of the emergency physician).
Background: Sedation and therapeutic hypothermia (TH) delay neurological responses and might reduce the accuracy of clinical examination to predict outcome after cardiac arrest (CA). Electroencephalography (EEG) and somato-sensory evoked potentials (SSEP) might significantly improve prognostication of post-CA coma, however, EEG and SSEP are not always available and require specific expertise for their interpretation. Automated video pupillometry is a novel electronic device that contains an infrared light camera which enables to measure quantitatively the percentage of pupillary reaction to a calibrated light stimulation. In a recent study of a cohort of comatose CA survivors (n=50 patients) it was found that quantitative PLR was more accurate than standard PLR (manual pen light) in predicting 3-month outcome, irrespective of temperature and sedation, and had comparable prognostic accuracy than electrophysiological exams, including electroencephalography (EEG) and somato-sensory evoked potentials (SSEP). Aim of the study: In light of these promising results, the investigators would like to confirm the prognostic value of quantitative PLR in a large multicenter cohort of comatose post-CA patients. Design of the study: Prospective, multicenter, observational outcome trial.
The study will investigate the effect of the oral antiplatelet agent ticagrelor (Brilique) when it is administrated through a nasogastric tube in comatose patients. The platelet function can be determined by various platelet function tests (PFT), Multiplate and VerifyNow . As control, the reference intervals from the literature are used. Futhermore, plasma concentrations of the active metabolite will be determined at aeveral timepoints after first intake of a bolus dose.
The purpose of this study is to determine if the Life Recovery Systems Thermosuit(R) System is able to quickly and conveniently cool patients who are comatose after resuscitation from cardiac arrest.
