Filter by:Phase 1 First-in Human randomized, open-label, active control standard of care study of the safety of HBN-1 administered as pharmacologically induced hypothermia as an adjunct to standard of care targeted temperature management in adult patients who have experienced out-of-hospital-cardiac arrest. HBN-1 will be administered IV as a loading dose infusion followed by a 12-hour maintenance infusion.
A small numbers of patients (10-15%) treated with cardiopulmonary resuscitation (CPR) are discharged from hospitals with a favorable neurologic outcome. However, a higher incidence of chest injuries (30-70%), mainly rib and sternum fractures, are observed among the survivors. It's no surprise that 6 months after cardiac arrest (CA) 50-70% of the patients who have survived continue to have pain and stress-related problems. Based on the need for the pain/stress treatment in these patients and several experimental evidences demonstrating neuroprotective features of anesthetics it is logical to presume that application of anesthesia during CPR may be indicated. In rodents exposed to hypoxic gas (5% 02, 95% N2) for 70 min, all seven animals died at the end of the experiments in the naloxone pre-treated group while only one out of seven rats died in the morphine pre-treated group, and five of seven rats died in the control group. In human volunteers, intravenously administered 60 mg of morphine did not alter cerebral blood flow and cerebral vascular resistance but markedly depressed cerebral oxygen uptake. Interestingly, in critical patients, morphine even in low doses is effective in relieving dyspnea by altering central perception and decreasing anxiety. In rats, morphine demonstrates dose- depending reduction of cerebral glucose utilization in limbic and forebrain regions. Thus, the main points of application for morphine in treatment of CA may be a reduction of oxygen/glucose consumption. Pre-treatment of zebrafish with ketamine protects against cardiac arrest-induced brain injury by inhibiting Ca2+ wave propagation and consequently it improves survival rate. Inhibition of NMDA receptors by ketamine reduces neuronal apoptosis and attenuates the systemic inflammatory response to tissue injury. The sympathomimetic effects of ketamine may facilitates recovery of systemic blood pressure during CPR. Retrospective investigations demonstrate that patients who are treated with opioids before or during CA have a statistically significantly higher survival rate and much better neurological outcome compared to untreated patients. Experimental studies have a limitation as all animals are treated with anesthesia and therefore survival rate varies between 50-90%. Thus, prospective research is urgently needed to investigate the influence of morphine or/and ketamine on survival and neurological outcome in patients with CA.
French guidelines for Cardio Pulmonary Resuscitation (CPR) consider Extra-Corporeal Life Support (ECLS) as one option in Refractory out-of hospital Cardiac Arrest (ROHCA) patients with a no-flow less than five minutes and absence of spontaneous circulation 30 minutes after initiation of advanced CPR. Duration of both pre-CPR arrest (no-flow) and of CPR (low-flow) have been systematically highlighted as crucial prognostic factors in all observational studies focused on ROHCA. In order to shorten the time to ECLS initiation, the most recent European Resuscitation Council guidelines recommend, in eligible ROHCA patients, a fast track access to ECLS implantation. CHRU Nancy elaborated an operational strategy which was designed to improve the enrolment of eligible ROHCA patients and to reduce the delay time between recognition and ECLS initiation. The objective of the present register was to assess prospectively the impact of this new operational strategy over a 5 years period.
Early stress-dose steroids are of uncertain efficacy in cardiac arrest. The current authors plan to conduct a pertinent mediation analysis using prospectively collected data from 2 prior randomized clinical trials of in-hospital cardiac arrest. These trials reported positive results on the vasopressin-steroids-epinephrine (VSE) combination. The current analysis is aimed at identifying mediators of the benefit associated with VSE, potentially attributable to its stress-dose steroid subcomponent. Tested mediators will include arterial pressure in the early postresuscitation period (primary), and arterial blood lactate in the early postresuscitation period and renal failure free days (secondary).
The investigators will compare the success rates and time to successful intubation of endotracheal intubation during simulated pediatric and infant resuscitation with and without chest compression using four different video-laryngoscopes.
