Filter by:Chest compression (CC) feedback devices are used to perform CC measurements effectively and accurately on patients in hospital beds. However, these devices do not take account of the compression of the mattress, which results in overestimation of CC depth. This study is the validation study to demonstrate that a new method using one accelerometer(U-cpr) is useful to overcome this limitation and thus measure compression depth more accurately when performing cardiopulmonary resuscitation (CPR) on patients.
The objective of the COOLCATH study is to compare the effect of the RhinoChill transnasal cooling system to current standard Blanketrol III cooling blanket in its ability to achieve therapeutic hypothermia (TH) induction for patients undergoing TH after cardiac arrest. The COOLCATH study will be a prospective, open-label randomized controlled trial comparing induction of TH efficacy and outcomes of patients following cardiac arrest. Any patient with return of spontaneous circulation (ROSC) following a cardiac arrest within the Essex Cardiothoracic Centre (CTC), or who is brought to the Essex CTC and is a candidate for TH will be considered for this study.
This PhD study is a sub study in a randomized clinical controlled multicenter trial named "TTH48" (ClinicalTrials.gov Identifier: NCT01689077). The TTH48 trial examines prolonged mild therapeutic hypothermia ("MTH") at 32-34°C in 24 versus 48 hours with the primary outcome Cerebral Performance Category after 6 month in comatose out-of-hospital cardiac arrest patients. THE OVERALL AIM OF THIS PhD STUDY IS TO INVESTIGATE THE CARDIAC FUNCTION AND THE HEMODYNAMICS BY BIOCHEMICAL CARDIAC MARKERS, ECHOCARDIOGRAPHY, BY ANALYZING THE USAGE OF INOTROPES/VASOPRESSORS AND BY ANALYZING ECG DATA FOR ARRHYTHMIAS IN THE 24 VERSUS 48 HOURS MTH GROUPS.
Clinical audit of in-hospital cardiac arrest management by in situ simulation Objectives: correct latent safety threats, knowledge gap, and crisis resource management (CRM) Design: clinical audit, observational sudy. Primary outcome: In Hospital resuscitation scale. Exploratory outcomes: non technical skills, validated stress inventory, and questionnaire on perceptions of the simulation and organisational changes needed.
Background: In cardiac arrest survival rates dramatically increase when bystanders are present and initiate Basic Life Support (BLS). However, even though serious efforts have been made, skill retention after a traditional time-based BLS course for laypeople remains suboptimal. In contrast, a mastery learning-based educational approach was shown to be efficacious and might be promising even for laypersons. Therefore the investigators aim to evaluate the impact of a mastery learning-based BLS course on skills retention of BLS in laypeople. Methods: Forty laypeople without previous BLS experiences will be randomized into the traditional time-based BLS course group (Control - TB group) or mastery learning-based group (Intervention - ML group). Both groups will receive BLS training consisting of 6 successive stations including diagnosis of cardiac arrest, chest compression, ventilation, one-rescuer BLS, two-rescuer BLS and AED use. In the ML group, subjects will deliberately practice and receive feedback at each station until a pre-set target level is reached. Subjects will be allowed to proceed to the next station only when they achieve the required target level of performance. In contrast, participants of the TB group will be taught the same 6 stations in two hours, according to standard American Heart Association BLS criteria. All subjects will have an assessment of knowledge and skills immediately after teaching (immediate post-test) and at four months (retention post-test). Implications: Previous research has shown that mastery learning-based education improves learners' procedural skill performance. The investigators study will determine the impact of a mastery learning-based BLS course on skill retention in laypeople.
The purpose of this study is to estimate the effect of medical treatment of electro-encephalographic status epilepticus on neurological outcome of patients with postanoxic encephalopathy after cardiac arrest.
Cardiac arrest is a major public health problem, with 700 000 cases per year , and a survival ranging from 4 to 33%. The post- anoxic encephalopathy remains the most serious complication with only a third of survivors . It is due to a series of phenomena involving microcirculation disorders . Cerebral oximetry is a new technique to evaluate the microcirculatory status . To this day it is used in cardiovascular surgery at risk of cerebral hypoperfusion where desaturation of cerebral oximetry is synonymous with ischemia and microcirculatory disorders. Therapeutic hypothermia is the only treatment improves the outcome of patients after extra- hospital cardiac arrest resuscitation . Its mechanisms of action seem to change all the phenomena responsible for microcirculatory reperfusion disorders . Currently it is recommended to practice hypothermia between 32 and 34 ° C. However, a recent study suggests a superiority of hypothermia at 32 ° C rather than 34 ° C. The hypothesis of this study is that cerebral oximetry value will be different in patients subjected to two different levels of therapeutic hypothermia in the aftermath of an extra- hospital cardiac arrest. These data allow a better understanding of the mechanisms underlying the benefit of this technique.
Compare the quality performance of rescuers and resuscitation outcomes of cardiac arrest patients in both groups with and without capnography feedback
To perform chest compression (CC) in the kneeling posture in hospital, we designed a stage with stairs, named the 'kneeling stool', on which a CC performer kneels beside a patient on a bed.This work is the validation study to demonstrate that the kneeling stool could be used for high quality hospital cardiopulmonary resuscitation (CPR) with the kneeling posture. We hypothesized that the quality of chest compression with a kneeling posture using the kneeling stool is equal to or superior to CC with a standing posture using the height adjustment mechanism of the bed.
