Filter by:Patients at risk of developing life-threatening heart rhythms may require the implantation of a small device called a cardioverter-defibrillator (ICD), which constantly monitors the heart rhythm and delivers an electrical shock to the heart when indicated, in order to return the heart back to a normal rhythm. Many thousands of these devices have been implanted and are electrically active in patients who collapse and need resuscitation. When a patient with an ICD collapses, the device may discharge without warning while a rescuer is performing external chest compressions (cardiac massage). Conventional ICDs placed below the left collar bone typically deliver 35-50 J energy when they discharge, but newer ICDs placed under the skin (S-ICD) alongside the breastbone deliver a larger energy when discharging; typically 50-80J energy. Rescuers performing external chest compressions on a patient during conventional ICD discharge have reported the sensation of a painful electrical shock and permanent nerve damage. In these situations, rescuers appear to have been exposed to electrical current from the ICD considerably in excess of that which is considered a safe threshold. Studies of surface current resulting from discharge of conventional ICDs have been reported in excess of 100 mA which is far in excess of the safe 1 mA limit, and puts the rescuer at considerable risk of tissue damage and possible dangerous heart rhythms. The newer S-ICDs deliver approximately 50% more energy and have the potential to result in exposure of a rescuer to even higher currents. With increasing numbers of the S-ICDs being implanted, and the inevitability that rescuers will soon find themselves exposed to leakage current from these devices, there is a need to examine the leakage currents arising from these devices and assess any subsequent risk to a rescuer performing external chest compressions.
This is a study to determine if surveillance monitoring of general ward patients can reduce cardio-pulmonary arrest while maintaining an acceptable false alarms rate for nursing workload.
Background: Central Venous catheter insertion technique and indwelling time are major risk factors for CVC colonisation. Colonisation occurs through microbial migration and biofilm formation along the catheter insertion tract. This study set out to determine the prevalence and associated factors for central venous catheter colonisation among critically ill patient. No data exists in this clinical setting addressing this topic. Methods: The study population included 100 participants with central venous catheters in situ for at least 24 hours. Catheter tip (distal 5-cm segment) and blood cultures (10mls peripheral blood) were obtained at the time of catheter removal.
Objective: To assess neurologic prognostication by early Transcranial Doppler Sonography (TCD) in comatose survivors after cardiac arrest. Design: Prospective study between May 2016 and November 2017 in a medical intensive care unit and cardiac intensive care unit in a university hospital. Patients: all comatose patients older than 18 years successfully resuscitated from an out-of-hospital cardiac arrest (OHCA). Patients for whom OHCA is associated with traumatic brain injury, no window for TCD measurements, or dead before neurological prognostication are excluded.
This is a clinical study based on the analysis of video-clip data of cardiopulmonary resuscitation (CPR) and clinical data for out of hospital cardiac arrest patients between 2011 and 2015. Aim of study is to compare the endotracheal intubation performance and CPR outcomes between videolaryngoscopy (VL) and direct laryngoscopy (DL) users.
Cardiac arrest is one of the most stressful situations to be managed. Our first study (MAX, accepted for publication BJA) clearly showed that it could not be compared to other urgent and stressful situations (malignant hyperthermia, anaphylactic shock, acute toxicity of local anesthetics, severe and symptomatic hyperkaliemia) whose management was significantly improved with the help of a digital cognitive aid. The present study exclusively deals with the management of cardiac arrest (recovery ward, or in the delivery room.) with the second generation of our digital cognitive aid, and explores new insights on how to better manage cardiac arrest with a digital cognitive aid in the hand of the leader.
This is a clinical study based on collected video-clip data of cardiopulmonary resuscitation for patients with suspected neck injury in multiple trauma between 2011 and 2015. The study aimed to compare all possible factors relating to ETI performance during CPR for truma patients between experienced video-laryngoscopy and direct- laryngoscopy users.
Post-resuscitation neurological impairment is associated with morbidity and especially with late mortality. Thus, because good neurological outcome is vital for a successful resuscitation, it is essential to have sufficient cerebral tissue perfusion and oxygenation during its application. Near-Infrared Spectroscopy (NIRS) is used to evaluate such conditions. NIRS is a non-invasive technique which provides real-time, continuous information about regional cerebral tissue oxygen saturation levels (regional SO2/rSO2). Research on NIRS has been done in many studies including cardiovascular surgery, neurosurgery and their intensive care processes and its effectiveness has been approved. However, there is limited data on its use in cardiac arrests. As stated in the current guidelines, sufficient speed and depth of chest compressions, few interruptions of compressions are key to a successful outcome of resuscitation. The studies with the mechanical chest compression devices showed that the earlier it was applied in out-of-hospital cases, the higher the rates of survival until hospitalization. There is not sufficient number of studies on the routine use of mechanical chest compression devices for in-hospital cases. In case the application of manual resuscitation is not convenient (during patient relocation, procedure at the angiography laboratory, and rush hours of emergency services when staff might fall short), alternative methods will be required. The aim of our study is to compare rSO2 levels measured during resuscitation with manual and mechanical devices in in-hospital (at the emergency department) witnessed cardiac arrest cases and to analyze the impact of both application method and perfusion levels on survival and neurological outcome.
The overall aim of this thesis is to identify the factors that may affect 13 year old students' acquisition of CPR skills and their willingness to act. The primary hypothesis is that the training method (intervention) influences the participants' acquisition of practical CPR skills and willingness to intervene. The study used a cluster randomized design, based on a randomization list generated by an independent statistician. The school classes were randomly assigned to different CPR training interventions. A strategic sample, where invitation to participate in the study was sent to the headmasters of all council schools, with seventh grade students, in two Swedish municipalities (140,000). Thus, the sample consists of participants with different cultural as well as socio-economic background. Eighteen of 24 schools agreed to participate. Four schools did not respond and two schools had a routine to offer CPR education only for grade nine (all six schools from the same municipality). The eighteen schools who agreed to participate consisted of sixty-eight classes with 1547 students. Prior to study participation, students and their guardians obtained a letter with study information. Study participation of the individual students was voluntary and all participants gave an oral informed consent. Inclusion criteria: seventh grade student in one of the participating schools. Exclusion criteria: student does not want to participate, student with a physical handicap that limited the physical performance, classes of students with development disabilities (these classes are age-integrated and have fewer students per class).
Optimal chest compression depth during CPR is 4.56cm which is at variance with the current guidelines of 5.0-6.0cm. A change in guidelines is only worthwhile if healthcare professionals can accurately judge a subtle reduction in chest compression depth during CPR by a relatively small amount.
