    Full Text Available ECPR is defined as the rapidly-deployed application of venoarterial extracorporeal membrane oxygenation, in patients with cardiac arrest, during cardiopulmonary resuscitation before the return of ROSC. ECPR is one of the most rapidly growing segments of ECLS, and is becoming more widespread. Consideration for institution of ECPR is given to patients with witnessed arrest, good quality CPR instituted within 5 min of arrest, in whom ROSC does not occur within 15 min, and who can complete cannulation within 30–60 min. Patients from both inpatient and out-of-hospital settings are candidates if they meet these criteria. Deep hypothermic cardiac arrest, such as cold-water drowning, should receive consideration for ECPR even after considerable duration of arrest. Available outcome data are based on retrospective observation studies, some with propensity matching, and suggests a higher chance for survival with ECPR. Published outcomes from ECPR, however, are difficult to interpret, since many centers classify their use of ECLS after ROSC, in addition to ECLS before ROSC, as ECPR. Both children and adults are candidates for ECPR, but the experience in children is weighted heavily toward those with a diagnosis of cardiac disease and arrest occurring within closely monitored units.

    Objective:To investigate application of cardiopulmonary resuscitation(CPR) measures within the golden minutes inEurope.Methods:The material was taken from theUniversityClinical Center ofKosovo -EmergencyCentre inPristina, during the two(2) year period(2010-2011).The collected date belong to the patients with cardiac arrest have been recorded in the patients' log book protocol at the emergency clinic.Results:During the2010 to2011 in the emergency center of theCUCK inPristina have been treated a total of269 patients with cardiac arrest, of whom159 or59.1% have been treated in2010, and110 patients or40.9% in2011.Of the269 patients treated in the emergency centre,93 or34.6% have exited lethally in the emergency centre, and176 or 65.4% have been transferred to other clinics.In the total number of patients with cardiac arrest, males have dominated with186 cases, or69.1%.The average age of patients included in the survey was56.7 year oldSD±16.0 years.Of the269 patients with cardiac arrest, defibrillation has been applied for93 or34.6% of patients.In the outpatient settings defibrillation has been applied for3 or3.2% of patients.Patients were defibrillated with application of one to four shocks. Of27 cases with who have survived cardiac arrest, none of them have suffered cardiac arrest at home,3 or11.1% of them have suffered cardiac arrest on the street, and24 or88.9% of them have suffered cardiac arrest in the hospital.5 out of27 patients survived have ended with neurological impairment.Cardiac arrest cases were present during all days of the week, but frequently most reported cases have been onMonday with32.0% of cases, and onFriday with24.5% of cases. Conclusions:All survivors from cardiac arrest have received appropriate medical assistance within10 min from attack, which implies that if cardiac arrest occurs near an institution health care(with an opportunity to provide the emergent health care) the rate of survival is higher.

  6. Ethical issues in cardiopulmonary resuscitation.

    If patients are to benefit from resuscitation, they must regain consciousness and their full faculties. In recent years, we have acquired important information about the natural history of neurological recovery from circulatory arrest. There are clinical tests that predict the outcome, both during ongoing cardiopulmonary resuscitation (CPR) and in the period after restoration of spontaneous circulation. The ability to predict neurological outcome at this stage offers a basis for certain ethical considerations, which are not exclusively centered on "do-not-attempt-resuscitation" (DNAR)- orders. Instead of being forced to make the decision that "I do not want CPR", the patient should be able to decide that "I want resuscitation to be discontinued, if you predict that I will not recover to a level of neurological function that is acceptable to me". Ideally, no competent patient should be given a DNAR-status without his or her consent. No CPR-attempt should be stopped, and no treatment decision for a patient recovering after CPR should be taken without knowing and assessing the available information. Good ethical decision-making requires reliable facts, which we now know are available.

  7. Airway management during cardiopulmonary resuscitation.

    2015-06-01

    This article evaluates the latest scientific evidence regarding airway management during in-hospital and out-of-hospital cardiopulmonary resuscitation (CPR). In the in-hospital setting, observational research suggested that the quality of CPR using 'no flow ratio' as a surrogate marker was improved when advanced airway techniques were used. A registry study demonstrated that an initial failed intubation attempt was associated with an average delay of 3 min in time to return of spontaneous circulation. A prospective observational study showed that the Glide Scope videolaryngoscope was associated with a first-pass success rate of 93%, with no differences between less and more experienced physicians. In the out-of-hospital setting, a registry study suggested that intubation leads to a better outcome compared with supraglottic airway devices. However, no advanced airway devices showed a better outcome than basic airway techniques. An observational study reported that the i-gel supraglottic airway device offers a first-pass insertion success rate of 90%, and was easier to establish than the Portex Soft Seal laryngeal mask airway. Other out-of-hospital observational studies showed that the laryngeal tube offers a lower first-pass insertion success rate than expected, and complications of this device may influence later definitive airway management and the outcome as a whole. Recent studies of airway management during CPR rely mostly on registry and observational designs. Prospective randomized trials are needed to determine the optimal approach to airway management during cardiac arrest, but have not yet been completed.

    Healthcare professionals, patients and their relatives are expected to discuss resuscitation together. This study aims to identify the differences in the knowledge base and understanding of these parties. Questionnaires examining knowledge and opinion on resuscitation matters were completed during interviews of randomly selected doctors, nurses and the general public. 70% doctors, 24% nurses and 0% of a public group correctly estimated survival to discharge following in-hospital resuscitation attempts. Deficiencies were identified in doctor and nurse knowledge of ethics governing resuscitation decisions. Public opinion often conflicts with ethical guidelines. Public understanding of the nature of cardiopulmonary arrests and resuscitation attempts; and of the implications of a \\'Do Not Attempt Resuscitation (DNAR)\\' order is poor. Television medical dramas are the primary source of resuscitation knowledge. Deficiencies in healthcare professionals\\' knowledge of resuscitation ethics and outcomes may compromise resuscitation decisions. Educational initiatives to address deficiencies are necessary. Parties involved in discussion on resuscitation do not share the same knowledge base reducing the likelihood of meaningful discussion. Public misapprehensions surrounding resuscitation must be identified and corrected during discussion.

    Despite substantial efforts to make cardiopulmonary resuscitation (CPR) algorithms known to healthcare workers, the outcome of CPR has remained poor during the past decades. Resuscitation teams often deviate from algorithms of CPR. Emerging evidence suggests that in addition to technical skills of individual rescuers, human factors such as teamwork and leadership affect adherence to algorithms and hence the outcome of CPR. This review describes the state of the science linking team interactions to the performance of CPR. Because logistical barriers make controlled measurement of team interaction in the earliest moments of real-life resuscitations challenging, our review focuses mainly on high-fidelity human simulator studies. This technique allows in-depth investigation of complex human interactions using precise and reproducible methods. It also removes variability in the clinical parameters of resuscitation, thus letting researchers study human factors and team interactions without confounding by clinical variability from resuscitation to resuscitation. Research has shown that a prolonged process of team building and poor leadership behavior are associated with significant shortcomings in CPR. Teamwork and leadership training have been shown to improve subsequent team performance during resuscitation and have recently been included in guidelines for advanced life support courses. We propose that further studies on the effects of team interactions on performance of complex medical emergency interventions such as resuscitation are needed. Future efforts to better understand the influence of team factors (e.g., team member status, team hierarchy, handling of human errors), individual factors (e.g., sex differences, perceived stress), and external factors (e.g., equipment, algorithms, institutional characteristics) on team performance in resuscitation situations are critical to improve CPR performance and medical outcomes of patients.

    Full Text Available Background: During recent years, cardiopulmonary resuscitation (CPR in hospital has received much attention. However, the survival rate of CPR in Iran’s hospitals is unknown. This study was designed to evaluate outcome of in-hospital CPR in Kashan. Methods: A longitudinal case registry study was conducted on all cases of in-hospital CPR during 6 months at 2002. Necessary data including; age, sex, underlying disease, working shift, time from cardiac arrest until initiating of CPR and until defibrillation, duration and result of CPR, frequency of tracheal intubations and time served for it were collected in a checklist. Results: In six months study, 206 cases of cardiopulmonary resuscitation attempted. The survival rate was similar for both sexes. Short-term survival observed in19.9% of cases and only 5.3% survived to discharge. Conclusions: Duration of CPR, time of the first defibrillation, response time and the location of cardiac arrest are the key predictors of survival to hospital discharge and in-hospital CPR strategies require improvement. This study promotes a national study on post CPR survival for accurate data on our performance in attention to chain of survival. KeyWords: Cardiopulmonary Resuscitation (CPR, Survival rate, Iran

    Rates of survival after cardiac arrest are low and correlate with the quality of cardiopulmonary resuscitation (CPR). Devices that deliver automated CPR (A-CPR) can provide sustained and effective chest compressions, which are especially useful during patient transfer and while simultaneous invasive procedures are being performed. The use of such devices can also release members of resuscitation teams for other work. This article presents a case study involving a man with acute myocardial infarction complicated by cardiogenic shock and pulmonary oedema. It describes how ED nursing and medical teams worked together to deliver A-CPR, discusses the use of A-CPR devices in a tertiary cardiac centre, and highlights the advantages of using such devices.

    Attempts at cardiopulmonary resuscitation (CPR) date from antiquity, but it is only in the last 50 years that a scientifically-based methodology has been developed. External chest compressions is the standard method for managing circulatory arrest, however, numerous alterations of this technique have been proposed in attempts to improve outcome from CPR. Defibrillation is the single most important therapy for the management of ventricular fibrillation or pulseless ventricular tachycardia. Adrenergic agents used to improve myocardial and cerebral perfusion are also the subject of considerable investigation with new agents entering clinical study. This paper reviews the history, current techniques and pharmacotherapy as well as controversial issues in the management of patients with cardiac arrest.

    Background Coma after cardiopulmonary resuscitation (CPR) is commonly seen in daily clinical practice. How to objectively evaluate brain function after CPR is essential to the following treatment. Coma patients after CPR had been studied prospectively at the Neuro-Intensive Care Unit of Xuanwu Hospital since 2002. In this study, we focused on the topic of how to evaluate the severity of coma after CPR .Methods From April 2002 to November 2004, patients in coma 24 hours after CPR were monitored, the evaluation methods included Glasgow coma score (GCS),brain stem reflection, and spinal reflection. Laboratory evaluation included electroencephalography (EEG),brainstem auditory evoked potential (BAEP), short latency somatosensory evoked potential (SLSEP), and transcranial Doppler (TCD) .Results Twenty-four of 35 patients(68.57%)were in deep coma. The GCS was 3 except for 2 patients;EEG was evaluated not less than grade Ⅳ except for 4 patients, BAEP was evaluated as grade Ⅲ except for 3 patients, and SLSEP was evaluated as grade Ⅲ except for 1 patient.Twenty-four patients died within 1 month and 11 of them(45.83%)were determined as brain death. Glasgow outcome score (GOS) was evaluated as grade Ⅰ. Eleven of the 35 patients survived and their consciousness changed from deep coma to coma vigil. EEG was evaluated as gradeⅠin 5 patients, BAEP and SLSEP were evaluated as grade Ⅰ in 3 patients, and GOS was all evaluated as grade Ⅱ among the 11 patients.Two patients(18.18%)regained consciousness in 35 and 90 days after cardiopulmonary resuscitation and GOS was evaluated as grade Ⅳ and Ⅲ, respectively.Conclusion Combined or continuous evaluation of clinical examinations and laboratory tests can accurately and objectively determine brain function after CPR.

    Infection of healthcare workers with the severe acute respiratory syndrome-associated coronavirus (SARS-CoV) is thought to occur primarily by either contact or large respiratory droplet transmission. However, infrequent healthcare worker infections occurred despite the use of contact and droplet precautions, particularly during certain aerosol-generating medical procedures. We investigated a possible cluster of SARS-CoV infections in healthcare workers who used contact and droplet precautions during attempted cardiopulmonary resuscitation of a SARS patient. Unlike previously reported instances of transmission during aerosol-generating procedures, the index case-patient was unresponsive, and the intubation procedure was performed quickly and without difficulty. However, before intubation, the patient was ventilated with a bag-valve-mask that may have contributed to aerosolization of SARS-CoV. On the basis of the results of this investigation and previous reports of SARS transmission during aerosol-generating procedures, a systematic approach to the problem is outlined, including the use of the following: 1) administrative controls, 2) environmental engineering controls, 3) personal protective equipment, and 4) quality control.

    Full Text Available Abstract The ability to respond quickly and effectively to a cardiac arrest situation rests on nurses being competent in the emergency life-saving procedure of cardiopulmonary resuscitation. The objective of the current study was to evaluate the types of trauma and survival of patients that require immediate cardiopulmonary resuscitation in trauma emergencies. A total of 13301 patients treated as accident victims between July 2004 and December 2006 were evaluated in a prospective study. Patients requiring immediate cardiopulmonary resuscitation at admission were identified. The type of injury and the survival of these patients were evaluated. Of the 65 patients included in the study, 30% had suffered from gunshot wounds, 19% had been run over, 18% had been involved in car crashes, 13% in motor cycle accidents, 9% stabbings, 1% by cycle accidents and 10% other types of accidents including burns, hangings and falls. In only 12 of these patients, immediate resuscitation was successful and procedure such as chest drainage, exploratory laparotomy and interventions in the surgical center were performed. However all patients evolved to death; eight within 24 hours, two between 24 and 48 hours and the other 2 after 48 hours. Immediate cardiopulmonary resuscitation after accidents is a sign of high mortality requiring further studies to review indication and the ethical aspects involved.

    Full Text Available Objective: To identify literature evidences related to actions to promote family's presence during cardiopulmonary resuscitation and invasive procedures in children hospitalized in pediatric and neonatal critical care units. Data sources : Integrative literature review in PubMed, SciELO and Lilacs databases, from 2002 to 2012, with the following inclusion criteria: research article in Medicine, or Nursing, published in Portuguese, English or Spanish, using the keywords "family", "invasive procedures", "cardiopulmonary resuscitation", "health staff", and "Pediatrics". Articles that did not refer to the presence of the family in cardiopulmonary resuscitation and invasive procedures were excluded. Therefore, 15 articles were analyzed. Data synthesis : Most articles were published in the United States (80%, in Medicine and Nursing (46%, and were surveys (72% with healthcare team members (67% as participants. From the critical analysis, four themes related to the actions to promote family's presence in invasive procedures and cardiopulmonary resuscitation were obtained: a to develop a sensitizing program for healthcare team; b to educate the healthcare team to include the family in these circumstances; c to develop a written institutional policy; d to ensure the attendance of family's needs. Conclusions: Researches on these issues must be encouraged in order to help healthcare team to modify their practice, implementing the principles of the Patient and Family Centered Care model, especially during critical episodes.

    AIM: To assess current knowledge and training in the management of contrast media reactions and cardiopulmonary resuscitation within a radiology department. MATERIALS AND METHODS: The standard of knowledge about the management of contrast media reactions and cardiopulmonary resuscitation among radiologists, radiographers and nurses were audited using a two-section questionnaire. Our results were compared against nationally accepted standards. Repeat audits were undertaken over a 28-month period. Three full audit cycles were completed. RESULTS: The initial audit confirmed that although a voluntary training programme was in place, knowledge of cardiopulmonary resuscitation techniques were below acceptable levels (set at 70%) for all staff members. The mean score for radiologists was 50%. Immediate changes instituted included retraining courses, the distribution of standard guidelines and the composition and distribution of two separate information handouts. Initial improvements were complemented by new wallcharts, which were distributed throughout the department, a series of lectures on management of contrast reactions and regular reviews with feedback to staff. In the third and final audit all staff groups had surpassed the required standard. CONCLUSION: Knowledge of contrast media reactions and resuscitation needs constant updating. Revision of skills requires a prescriptive programme; visual display of advice is a constant reminder. It is our contention all radiology departmental staff should consider it a personal duty to maintain their resuscitation skills at appropriate standards. O'Neill, J.M., McBride, K.D.(2001).

    For decades, survival rates of cardiac arrest following trauma were reported between 0 and 2 %. Since 2005, survival rates have increased with a wide range up to 39 % and good neurological recovery in every second person injured for unknown reasons. Especially in children, high survival rates with good neurologic outcomes are published. Resuscitation following traumatic cardiac arrest differs significantly from nontraumatic causes. Paramount is treatment of reversible causes, which include massive bleeding, hypoxia, tension pneumothorax, and pericardial tamponade. Treatment of reversible causes should be simultaneous. Chest compression is inferior following traumatic cardiac arrest and should never delay treatment of reversible causes of the traumatic cardiac arrest. In massive bleeding, bleeding control has priority. Damage control resuscitation with permissive hypotension, aggressive coagulation therapy, and damage control surgery represent the pillars of initial treatment. Cardiac arrest due to hypoxia should be resolved by airway management and ventilation. Tension pneumothorax should be decompressed by finger thoracostomy, pericardial tamponade by resuscitative thoracotomy. In addition, resuscitative thoracotomy allows direct and indirect bleeding control. Untreated impact brain apnea may rapidly lead to cardiac arrest and requires quick opening of the airway and effective oxygenation. Established algorithms for treatment of cardiac arrest following trauma enable a safe, structured, and effective management.

    To discuss risks and benefits of interhospital transport of children in cardiac arrest undergoing cardiopulmonary resuscitation. Narrative review. Not applicable. Transporting children in cardiac arrest with ongoing cardiopulmonary resuscitation between hospitals is potentially lifesaving if it enables access to resources such as extracorporeal support, but may risk transport personnel safety. Research is needed to optimize outcomes of patients transported with ongoing cardiopulmonary resuscitation and reduce risks to the staff caring for them.

    "Electrical shock is the physiological reaction or injury caused by electric current passing through the human body. It occurs upon contact of a human body part with any source of electricity that causes a sufficient current through the skin, muscles, or hair causing undesirable effects ranging from simple burns to death." Ventricular fibrillation is believed to be the most common cause of death after electrical shock. "The ideal duration of cardiac resuscitation is unknown. Typically prolonged cardiopulmonary resuscitation is associated with poor neurologic outcomes and reduced long term survival. No consensus statement has been made and traditionally efforts are usually terminated after 15-30 minutes." The case under discussion seems worthy of the somewhat detailed description given. It is for a young man who survived after 65 minutes after electrical shock (ES) after prolonged high-quality cardiopulmonary resuscitation (CPR), multiple defibrillations, and artificial ventilation without any sequelae. Early start of adequate chest compressions and close adherence to advanced cardiac life support protocols played a vital role in successful CPR.

    Full Text Available Background: Cardiopulmonary resuscitation (CPR is a series of actions performed on cardiac arrest patients. Not all patients receiving CPR can survive. The outcome of CPR is influenced by several factors. This study was conducted to determine the success rate of CPR and the factors influencing it in Dr. Hasan Sadikin General Hospital in 2013. Methods: This study was conducted by using 168 patient medical records who underwent CPR and met the inclusion criteria in the Resuscitation Room of Dr. Hasan Sadikin General Hospital from January to December 2013. The collected data consisted of age, gender, pre-arrest diagnosis, initial rhythm, response time and clinical outcome of CPR. The results were expressed in frequencies and percentage. The data were analyzed using the chi-square test. Results: The Success rate of CPR was 15.5%. The success rate was higher in patients with cardiac prearrest diagnoses (8.33%, p=0.024. The most common initial rhythm was unshockable rhythms (83.92%, yet patients with shockable heart rhythms had higher success rates (40.74%, p<0.001. All of the surviving patients had response time within the first minute from cardiac arrest. Conclusions: Success rate of CPR in the resuscitation room of Dr. Hasan Sadikin General Hospital during 2013 is still low. The factors influencing the survival rate are the pre-arrest diagnosis and initial heart rhythm.

    1997-06-06

    In light of the medically relevant features of the ancient Egyptian mouth-opening ceremony, the question of the effectiveness of medical practices in Egypt thousands of years ago is examined, whereby the religious and cultural framework also plays a significant role. In the Land on the Nile myth and reality clearly generated special conditions which favoured the systematic treatment of questions of resuscitation. Numerous examples show that this had practical consequences in the area of everyday medicine. In addition, rebirth and resurrection were central elements of the cult of the dead which had exact medical equivalents. These equivalents may demonstrate the advanced state of resuscitation practices in Egypt at that time. In this context, a reconstruction of an ancient Egyptian mouth-opening instrument is presented. In the cult of the dead, this instrument played a role which can be compared to the function of a modern laryngoscope. It appears possible that at the time of the pyramids the Egyptians already had an understanding of the technology required to perform instrument-aided artificial respiration. Whether or not they actually possessed a fundamental knowledge of the principles of cardio-pulmonary resuscitation remains unclear. Nevertheless, the astonishingly functional characteristics of the reconstructed mouth-opening instrument suggest that it was developed for more than purely symbolic purposes.

    Cardiopulmonary resuscitation (CPR) during ambulance transport can be a safety risk for providers and can affect CPR quality. In many Asian countries with basic life support (BLS) systems, patients experiencing out-of-hospital cardiac arrest (OHCA) are routinely transported in ambulances in which CPR is performed. This paper aims to make recommendations on best practices for CPR during ambulance transport in BLS systems. A panel consisting of 20 experts (including 4 North Americans) in emergency medical services (EMS) and resuscitation science was selected, and met over two days. We performed a literature review and selected 33 candidate issues in five core areas. Using Delphi methodology, the issues were classified into dichotomous (yes/no), multiple choice, and ranking questions. Primary consensus between experts was reached when there was more than 70% agreement. Questions with 60-69% agreement were made more specific and were submitted for a second round of voting. The panel agreed upon 24 consensus statements with more than 70% agreement (2 rounds of voting). The recommendations cover the following: length of time on the scene; advanced airway at the scene; CPR prior to transport; rhythm analysis and defibrillation during transport; prehospital interventions; field termination of resuscitation (TOR); consent for TOR; destination hospital; transport protocol; number of staff members; restraint systems; mechanical CPR; turning off of the engine for rhythm analysis; alternative CPR; and feedback for CPR quality. Recommendations for CPR during ambulance transport were developed using the Delphi method. These recommendations should be validated in clinical settings.

    2017-01-01

    BACKGROUND: Dentists as health care providers should maintain a competence in resuscitation. This cannot be overemphasized by the fact that the population in our country is living longer with an increasing proportion of medically compromised persons in the general population. This preliminary study aimed to assess the knowledge and attitude of general dentists towards cardiopulmonary resuscitation (CPR). METHODS: A cross-sectional study was carried out among 250 licensed general dental practitioners working in ministry of health. Data were obtained through electronic self-administered questionnaire consisting of demographic data of general dentists, and their experience, attitude and knowledge about CPR based on the 2010 American Heart Association guidelines update for CPR. RESULTS: Totally 208 general dentists took part in the present study giving a response rate of 83.2%. Only 36% of the participants demonstrated high knowledge on CPR, while 64% demonstrated low knowledge. Participants’ age, gender, nationality, years of experience, career hierarchy, and formal CPR training were associated significantly with CPR knowledge. Almost all the participants (99%) felt that dentists needed to be competent in basic resuscitation skills and showed a positive attitude towards attending continuing dental educational programs on CPR. CONCLUSION: This study showed that majority of general dental practitioners in Kuwait had inadequate knowledge on CPR. It was also found that CPR training significantly influenced the CPR knowledge of the participants. Therefore, training courses on CPR should be regularly provided to general dentists in the country.

    Despite widespread training in basic life support (BLS) and advanced cardiovascular life support (ACLS) among hospital personnel, the likelihood of survival from in-hospital cardiac arrests remains low. In 2006 a university-affiliated tertiary medical center initiated a cardiopulmonary (CPR) resuscitation redesign project. REDESIGNING THE HOSPITAL'S RESUSCITATION SYSTEM: The CPR Committee developed the interventions on the basis of a large-scale view of the process of delivering BLS and ACLS, identification of key decision nodes and actions, and compartmentalization of specific functions. It was proposed that arrest management follow a steady progression in a two-layer scheme from BLS to ACLS. Handouts describing team structure and specific roles were given to all code team providers and house staff at the start of their month-long rotations. To further increase role clarity and team organization, daily morning and evening meetings of the arrest team were instituted. Site-specific BLS training, on-site ACLS refresher training, and defibrillator training were initiated. Project elements also included use of unannounced mock codes to provide system oversight; preparation and distribution of cognitive aids (printed algorithms, dosing guides, and other checklists to ensure compliance with ACLS protocols), identification of patients who may be unstable or a source of concern, event review and analysis of arrests and other critical events, and a CPR website. A mature hospital-based resuscitation system should include definition of arrest trends and resuscitation needs, development of local methods for approaching the arresting patient, an emphasis on prevention, establishment of training programs tailored to meet specific hospital needs, system examination and oversight, and administrative processes that maximize interaction between all components.

    BACKGROUND: Batroxobin has been found to have protective effect on cerebral ischemia-reperfusion,and cardiopulmonary resuscitation (CPR) is the common cause of global brain ischemia-reperfusion.OBJECTIVE: To observe the effect of Batroxobin on the morphological results of cerebral cortex and hippocampus in rabbit models of CPR, and the changes of serum concentration of tumor necrosis factor alpha (TNF- α) after CPR.DESIGN: A randomized controlled observation.SETTING: Laboratory of the Department of Burns, Changhai Hospital affiliated to the Second Military Medical University of Chinese PLA.MATERIALS: Thirty healthy New Zealand rabbits of 2.5 - 3.0 kg, either male or female, were used. Kits for TNF- α determination were provided by LIFEKEY BioMeditech Company (USA).METHODS: The experiments were carried out in the laboratory of Department of Burns, Changhai Hospital from February 2001 to January 2002. The 32 rabbits were randomly divided into sham-operated group (n=8),conventional resuscitation group (n=12) and Batroxobin-treated group (n=12). The animals in the conventional resuscitation group and Batroxobin-treated group were anesthetized, then induced into modified Pittsburg's model of mechanical ventricular fibrillation. Sham-operated group was discharged on the chest wall, which did not cause ventricular fibrillation. Conventional resuscitation group and Batroxobin-treated group were exposed to 6 minutes of cardiac arrest induced by ventricular fibrillation, then the resuscitation began. A dosage of 0.3 Bu/kg of Batroxobin was administered to the rabbits in the Batroxobin-treated group at the beginning of resuscitation. Blood sample was collected at 4 and 12 hours after CPR to determine the concentration of TNF- α in serum. After the second blood collection, brain tissue was taken out immediately,and the forms of nerve cells in cerebral cortex and hippocampal CA1 region were observed under light microscope.MAIN OUTCOME MEASURES: ① TNF-α concentration in

    Full Text Available OBJECTIVE: To assess survival of patients undergoing cerebral cardiopulmonary resuscitation maneuvers and to identify prognostic factors for short-term survival. METHODS: Prospective study with patients undergoing cardiopulmonary resuscitation maneuvers. RESULTS: The study included 150 patients. Spontaneous circulation was re-established in 88 (58% patients, and 42 (28% were discharged from the hospital. The necessary number of patients treated to save 1 life in 12 months was 3.4. The presence of ventricular fibrillation or tachycardia (VF/VT as the initial rhythm, shorter times of cardiopulmonary resuscitation maneuvers and cardiopulmonary arrest, and greater values of mean blood pressure (BP prior to cardiopulmonary arrest were independent variables for re-establishment of spontaneous circulation and hospital discharge. The odds ratios for hospital discharge were as follows: 6.1 (95% confidence interval [CI] = 2.7-13.6, when the initial rhythm was VF/VT; 9.4 (95% CI = 4.1-21.3, when the time of cerebral cardiopulmonary resuscitation was 70 mmHg. CONCLUSION: The presence of VF/VT as the initial rhythm, shorter times of cerebral cardiopulmonary resuscitation and of cardiopulmonary arrest, and a greater value of BP prior to cardiopulmonary arrest were independent variables of better prognosis.

    Objective To evaluate the efficacy of the continuation of cardiopulmonary resuscitation (CPR) following transportation to the emergency department in a Chinese hospital after unsuccessful emergency medical services (EMS) CPR. Methods From January 2002 to December 2007, emergency records of non-traumatic patients who were transported to a tertiary teaching hospital after unsuccessful EMS CPR were reviewed. Results Eigty-five patients were included, and 13 patients (15%) accomplished restoration of spontaneous circulation in our emergency department. Resuscitative possibility reached zero at around 23 minutes. One patient was discharged with a favourable neurologic outcome. Conclusions This study shows that the continuation of CPR is not futile and may improve outcomes. The outcomes should be re-evaluatad in the future when prehospital information can be combined with in-hospital information.

  8. Cardiopulmonary resuscitation for cardiac arrest: the importance of uninterrupted chest compressions in cardiac arrest resuscitation.

    2012-10-01

    Over the last decade, the importance of delivering high-quality cardiopulmonary resuscitation (CPR) for cardiac arrest patients has become increasingly emphasized. Many experts are in agreement concerning the appropriate compression rate, depth, and amount of chest recoil necessary for high-quality CPR. In addition to these factors, there is a growing body of evidence supporting continuous or uninterrupted chest compressions as an equally important aspect of high-quality CPR. An innovative resuscitation protocol, called cardiocerebral resuscitation, emphasizes uninterrupted chest compressions and has been associated with superior rates of survival when compared with traditional CPR with standard advanced life support. Interruptions in chest compressions during CPR can negatively impact outcome in cardiac arrest; these interruptions occur for a range of reasons, including pulse determinations, cardiac rhythm analysis, electrical defibrillation, airway management, and vascular access. In addition to comparing cardiocerebral resuscitation to CPR, this review article also discusses possibilities to reduce interruptions in chest compressions without sacrificing the benefit of these interventions.

  9. Cardiopulmonary resuscitation in the elderly: a clinical and ethical perspective

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    The daily practice of cardiopulmonary resuscitation (CPR) in elderly patients has brought up the attention of outcome research and resource allocation. Determinants to predict survival have been well identified. There has been empirical evidence that CPR is of doubtful utility in the geriatric population, more studies have showed controversial data. Sometimes situations in which CPR needs to be given in the elderly, causes stress to healthcare providers, due to lack of communication of the patient's wishes and the belief that it will not be successful. It is of importance to state that we have the duty to identify on time the patients that will most likely benefit from CPR, and find out the preferences of the same. Whenever it is possible to institute these guidelines, we will avoid patient suffering.

  11. Coronary blood flow during cardiopulmonary resuscitation in swine

    Energy Technology Data Exchange (ETDEWEB)

    Bellamy, R.F.; DeGuzman, L.R.; Pedersen, D.C.

    1984-01-01

    Recent papers have raised doubt as to the magnitude of coronary blood flow during closed-chest cardiopulmonary resuscitation. We will describe experiments that concern the methods of coronary flow measurement during cardiopulmonary resuscitation. Nine anesthetized swine were instrumented to allow simultaneous measurements of coronary blood flow by both electromagnetic cuff flow probes and by the radiomicrosphere technique. Cardiac arrest was caused by electrical fibrillation and closed-chest massage was performed by a Thumper (Dixie Medical Inc., Houston). The chest was compressed transversely at a rate of 66 strokes/min. Compression occupied one-half of the massage cycle. Three different Thumper piston strokes were studied: 1.5, 2, and 2.5 inches. Mean aortic pressure and total systemic blood flow measured by the radiomicrosphere technique increased as Thumper piston stroke was lengthened (mean +/- SD): 1.5 inch stroke, 23 +/- 4 mm Hg, 525 +/- 195 ml/min; 2 inch stroke, 33 +/- 5 mm Hg, 692 +/- 202 ml/min; 2.5 inch stroke, 40 +/- 6 mm Hg, 817 +/- 321 ml/min. Both methods of coronary flow measurement (electromagnetic (EMF) and radiomicrosphere (RMS)) gave similar results in technically successful preparations (data expressed as percent prearrest flow mean +/- 1 SD): 1.5 inch stroke, EMF 12 +/- 5%, RMS 16 +/- 5%; 2 inch stroke, EMF 30 +/- 6%, RMS 26 +/- 11%; 2.5 inch stroke, EMF 50 +/- 12%, RMS 40 +/- 20%. The phasic coronary flow signal during closed-chest compression indicated that all perfusion occurred during the relaxation phase of the massage cycle. We concluded that coronary blood flow is demonstrable during closed-chest massage, but that the magnitude is unlikely to be more than a fraction of normal.

  12. Cardiopulmonary resuscitation decisions in the emergency department: An ethnography of tacit knowledge in practice.

    Despite media images to the contrary, cardiopulmonary resuscitation in emergency departments is often unsuccessful. The purpose of this ethnographic study was to explore how health care professionals working in two emergency departments in the UK, make decisions to commence, continue or stop resuscitation. Data collection involved participant observation of resuscitation attempts and in-depth interviews with nurses, medical staff and paramedics who had taken part in the attempts. Detailed case examples were constructed for comparative analysis. Findings show that emergency department staff use experience and acquired tacit knowledge to construct a typology of cardiac arrest categories that help them navigate decision making. Categorisation is based on 'less is more' heuristics which combine explicit and tacit knowledge to facilitate rapid decisions. Staff then work as a team to rapidly assimilate and interpret information drawn from observations of the patient's body and from technical, biomedical monitoring data. The meaning of technical data is negotiated during staff interaction. This analysis was informed by a theory of 'bodily' and 'technical' trajectory alignment that was first developed from an ethnography of death and dying in intensive care units. The categorisation of cardiac arrest situations and trajectory alignment are the means by which staff achieve consensus decisions and determine the point at which an attempt should be withdrawn. This enables them to construct an acceptable death in highly challenging circumstances.

    Cardio-pulmonary resuscitation (CPR) may generate sufficient cerebral perfusion pressure to make the patient conscious. The incidence and management of this phenomenon are not well described. This systematic review aims to identifying cases where CPR-induced consciousness is mentioned in the literature and explore its management options. The databases Medline, PubMed, EMBASE, Cinahl and the Cochrane Library were searched from their commencement to the 8th July 2014. We also searched Google (scholar) for grey literature. We combined MeSH terms and text words for consciousness and CPR, and included studies of all types. The search yielded 1997 unique records, of which 50 abstracts were reviewed. Nine reports, describing 10 patients, were relevant. Six of the patients had CPR performed by mechanical devices, three of these patients were sedated. Four patients arrested in the out-of-hospital setting and six arrested in hospital. There were four survivors. Varying levels of consciousness were described in all reports, including purposeful arm movements, verbal communication, and resuscitation interference. Management strategies directed at consciousness were offered to six patients and included both physical and chemical restraints. CPR-induced consciousness was infrequently reported in the medical literature, and varied in management. Given the increasing use of mechanical CPR, guidelines to identify and manage consciousness during CPR are required. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    Although it is widely known that adults may sustain fractures of the anterior and/or lateral aspects of the ribs due to cardiopulmonary resuscitation (CPR) efforts, relatively little is written about the generation of CPR-related rib fractures in the infant age range. In a series of 70 consecutive autopsies in infants ranging in age from 2 weeks to 8 months, with no history or indications of injury, the parietal pleura of the thoracic cage was stripped and the ribs carefully examined for fracture. Subtle fractures of the anterolateral aspects of the ribs were discovered in 8 (11%) of the 70 cases. In 7 of the 8 cases, multiple ribs were fractured (ranging up to 10 rib fractures), and in 5 of these cases, the rib fractures were bilateral. All of the rib fractures were subtle, had little if any associated blood extravasation, and would have been easily missed had the parietal pleura not been stripped. These anterolateral rib fractures in infants are the likely correlate of anterolateral rib fractures that are not uncommonly seen in the adult population, resulting from resuscitation efforts. The rib fractures are subtle and may not be identified unless the parietal pleura is stripped.

    Mass cardiopulmonary resuscitation (CPR) 99 in Singapore was a large-scale multi-organisational effort to increase awareness and impart basic cardiac life support skills to the lay public. Mass CPR demonstrations followed by small group manikin practice with instructor guidance was conducted simultaneously in three centres, four times a day. The exercise enlisted 15 community organisations and received the support of 19 other organisations. Three hundred and ninety-eight manikins and 500 instructors ('I's) were mobilised to teach an audience of 6000 participants ('P's). Two surveys, for 'I's and 'P's were conducted with respondent rates of 65.8% and 50%, respectively. 73.6% of the P-respondents ('P-R's) indicated that they attended the event to increase their knowledge. 66.9% were willing to attend a more comprehensive CPR course. Concerns and perceptions in performing bystander CPR were assessed.

    Rescuers' psychological competence, particularly their motivation, can improve the cardiopulmonary resuscitation outcomes. Data were collected using semistructured interviews with 24 cardiopulmonary resuscitation team members and analyzed through deductive content analysis based on Vroom's expectancy theory. Nine generic categories were developed: (i) estimation of the chance of survival; (ii) estimation of self-efficacy; (iii) looking for a sign of effectiveness; (iv) supportive organizational structure; (v) revival; (vi) acquisition of external incentives; (vii) individual drives; (viii) commitment to personal values; and (ix) avoiding undesirable social outcomes. When professional rescuers were called to perform cardiopulmonary resuscitation, they subjectively evaluated the patient's chance of survival, the likelihood of achieving of the desired outcome, and the ability to perform cardiopulmonary resuscitation interventions. If their evaluations were positive, and the consequences of cardiopulmonary resuscitation were considered favorable, they were strongly motivated to perform it. Beyond the scientific aspects, the motivation to perform cardiopulmonary resuscitation was influenced by intuitive, emotional, and spiritual aspects. © 2017 John Wiley & Sons Australia, Ltd.

    Full Text Available Interruptions in cardiopulmonary resuscitation (CPR compromise defibrillation success. However, CPR must be interrupted to analyze the rhythm because although current methods for rhythm analysis during CPR have high sensitivity for shockable rhythms, the specificity for nonshockable rhythms is still too low. This paper introduces a new approach to rhythm analysis during CPR that combines two strategies: a state-of-the-art CPR artifact suppression filter and a shock advice algorithm (SAA designed to optimally classify the filtered signal. Emphasis is on designing an algorithm with high specificity. The SAA includes a detector for low electrical activity rhythms to increase the specificity, and a shock/no-shock decision algorithm based on a support vector machine classifier using slope and frequency features. For this study, 1185 shockable and 6482 nonshockable 9-s segments corrupted by CPR artifacts were obtained from 247 patients suffering out-of-hospital cardiac arrest. The segments were split into a training and a test set. For the test set, the sensitivity and specificity for rhythm analysis during CPR were 91.0% and 96.6%, respectively. This new approach shows an important increase in specificity without compromising the sensitivity when compared to previous studies.

    Full Text Available Capnography continues to be an important tool in measuring expired carbon dioxide (CO 2 . Most recent Advanced Cardiac Life Support (ACLS guidelines now recommend using capnography to ascertain the effectiveness of chest compressions and duration of cardiopulmonary resuscitation (CPR. Based on an extensive review of available published literature, we selected all available peer-reviewed research investigations and case reports. Available evidence suggests that there is significant correlation between partial pressure of end-tidal CO 2 (PETCO 2 and cardiac output that can indicate the return of spontaneous circulation (ROSC. Additional evidence favoring the use of capnography during CPR includes definitive proof of correct placement of the endotracheal tube and possible prediction of patient survival following cardiac arrest, although the latter will require further investigations. There is emerging evidence that PETCO 2 values can guide the initiation of extracorporeal life support (ECLS in refractory cardiac arrest (RCA. There is also increasing recognition of the value of capnography in intensive care settings in intubated patients. Future directions include determining the outcomes based on capnography waveforms PETCO 2 values and determining a reasonable duration of CPR. In the future, given increasing use of capnography during CPR large databases can be analyzed to predict outcomes.

    This simulation trial aimed to compare the quality of cardiopulmonary resuscitation (CPR) with and without the newly-developed CPR support application on smartphones. In this trial, participants were randomly assigned to either the CPR support application group or the control group, stratified by sex and previous CPR training. Participants' CPR skills were evaluated by a 2-min case-based scenario test using the Leardal Resusci Anne PC Skill reporting Manikin System(®). The outcome measures were the proportion of chest compressions performed in each group and the number of total chest compressions and appropriate chest compressions performed during the 2-min test period. A total of 84 participants were enrolled and completed the protocol. All participants in the CPR support application group performed chest compressions, compared with only 31 (75.6%) in the control group (Psmartphones contributed to increasing the implementation rate and the number of total chest compressions performed and may assist in improving the survival rate for out-of-hospital cardiac arrests (UMIN000004740).

    To understand perceived barriers to providing cardiopulmonary resuscitation (CPR) education, implementation processes, and practices in high schools. Iowa has required CPR as a graduation requirement since 2011 as an unfunded mandate. A cross-sectional study was performed through multiple choice surveys sent to Iowa high schools to collect data about school demographics, details of CPR programs, cost, logistics, and barriers to implementation, as well as automated external defibrillator training and availability. Eighty-four schools responded (26%), with the most frequently reported school size of 100-500 students and faculty size of 25-50. When the law took effect, 51% of schools had training programs already in place; at the time of the study, 96% had successfully implemented CPR training. Perceived barriers to implementation were staffing, time commitment, equipment availability, and cost. The average estimated startup cost was <$1000 US, and the yearly maintenance cost was <$500 with funds typically allocated from existing school resources. The facilitator was a school official or volunteer for 81% of schools. Average estimated training time commitment per student was <2 hours. Automated external defibrillators are available in 98% of schools, and 61% include automated external defibrillator training in their curriculum. Despite perceived barriers, school CPR training programs can be implemented with reasonable resource and time allocations. Copyright © 2016 Elsevier Inc. All rights reserved.

    Objective The objective of this study was to analyze the clinical profile of patients with in-hospital cardiac arrest using the Utstein style. Methods This study is an observational, prospective, longitudinal study of patients with cardiac arrest treated in intensive care units over a period of 1 year. Results The study included 89 patients who underwent cardiopulmonary resuscitation maneuvers. The cohort was 51.6% male with a mean age 59.0 years. The episodes occurred during the daytime in 64.6% of cases. Asystole/bradyarrhythmia was the most frequent initial rhythm (42.7%). Most patients who exhibited a spontaneous return of circulation experienced recurrent cardiac arrest, especially within the first 24 hours (61.4%). The mean time elapsed between hospital admission and the occurrence of cardiac arrest was 10.3 days, the mean time between cardiac arrest and cardiopulmonary resuscitation was 0.68 min, the mean time between cardiac arrest and defibrillation was 7.1 min, and the mean duration of cardiopulmonary resuscitation was 16.3 min. Associations between gender and the duration of cardiopulmonary resuscitation (19.2 min in women versus 13.5 min in men, p = 0.02), the duration of cardiopulmonary resuscitation and the return of spontaneous circulation (10.8 min versus 30.7 min, p < 0.001) and heart disease and age (60.6 years versus 53.6, p < 0.001) were identified. The immediate survival rates after cardiac arrest, until hospital discharge and 6 months after discharge were 71%, 9% and 6%, respectively. Conclusions The main initial rhythm detected was asystole/bradyarrhythmia; the interval between cardiac arrest and cardiopulmonary resuscitation was short, but defibrillation was delayed. Women received cardiopulmonary resuscitation for longer periods than men. The in-hospital survival rate was low. PMID:28099640

    Background: One dilemma in the end-of-life care is making decisions for conducting cardiopulmonary resuscitation (CPR). This dilemma is perceived in different ways due to the influence of culture and religion. This study aimed to understand the experiences of CPR team members about the do-not-resuscitate order. Methods: CPR team members were interviewed, and data were analyzed using a conventional content analysis method. Results: Three categories and six subcategories emerged: “The dilemma between revival and suffering” with the subcategories of “revival likelihood” and “death as a cause for comfort;” “conflicting situation” with the subcategories of “latent decision” and “ambivalent order;” and “low-quality CPR” with the subcategories of “team member demotivation” and “disrupting CPR performance.” Conclusion: There is a need for the development of a contextual guideline, which is required for respecting the rights of patients and their families and providing legal support to health-care professionals during CPR.

    The alleviation of brain injury is a key issue following cardiopulmonary resuscitation (CPR). Hydrogen sulfide (H2S) is hypothesized to be involved in the pathophysiological process of ischemia-reperfusion injury, and exerts a protective effect on neurons. The aim of the present study was to investigate the effects of H2S on neural functions following cardiac arrest (CA) in rats. A total of 60 rats were allocated at random into three groups. CA was induced to establish the model and CPR was performed after 6 min. Subsequently, sodium hydrosulfide (NaHS), hydroxylamine or saline was administered to the rats. Serum levels of H2S, neuron-specific enolase (NSE) and S100β were determined following CPR. In addition, neurological deficit scoring (NDS), the beam walking test (BWT), prehensile traction test and Morris water maze experiment were conducted. Neuronal apoptosis rates were detected in the hippocampal region following sacrifice. After CPR, as the H2S levels increased or decreased, the serum NSE and S100β concentrations decreased or increased, respectively (P<0.0w. The NDS results of the NaHS group were improved compared with those of the hydroxylamine group at 24 h after CPR (P<0.05). In the Morris water maze experiment, BWT and prehensile traction test the animals in the NaHS group performed best and rats in the hydroxylamine group performed worst. At day 7, the apoptotic index and the expression of caspase-3 were reduced in the hippocampal CA1 region, while the expression of Bcl-2 increased in the NaHS group; and results of the hydroxylamine group were in contrast. Therefore, the results of the present study indicate that H2S is able to improve neural function in rats following CPR. PMID:26893650

    Full Text Available Background: Insufficient knowledge of the risks and complications of cardiopulmonary resuscitation (CPR may be an obstructive factor for CPR, however, particularly for patients who are not clearly suffering out of hospital cardiopulmonary arrest (OH-CPA. The object of this study was to clarify the potential complication, the safety of bystander CPR in such cases. Materials and Methods: This study was a population-based observational case series. To be enrolled, patients had to have undergone CPR with chest compressions performed by lay persons, had to be confirmed not to have suffered OHCPA. Complications of bystander CPR were identified from the patients′ medical records and included rib fracture, lung injury, abdominal organ injury, and chest and/or abdominal pain requiring analgesics. In our emergency department, one doctor gathered information while others performed X-ray and blood examinations, electrocardiograms, and chest and abdominal ultrasonography. Results: A total of 26 cases were the subjects. The mean duration of bystander CPR was 6.5 minutes (ranging from 1 to 26. Nine patients died of a causative pathological condition and pneumonia, and the remaining 17 survived to discharge. Three patients suffered from complications (tracheal bleeding, minor gastric mucosal laceration, and chest pain, all of which were minimal and easily treated. No case required special examination or treatment for the complication itself. Conclusion: The risk and frequency of complications due to bystander CPR is thought to be very low. It is reasonable to perform immediate CPR for unconscious victims with inadequate respiration, and to help bystanders perform CPR using the T-CPR system.

    To examine the effectiveness of a "cardiopulmonary resuscitation song" in improving the basic life support skills of secondary school students. This pre-test/post-test control design study enrolled secondary school students from two middle schools randomly chosen in Córdoba, Andalucia, Spain. The study included 608 teenagers. A random sample of 87 students in the intervention group and 35 in the control group, aged 12-14 years were selected. The intervention included a cardiopulmonary resuscitation song and video. A questionnaire was conducted at three-time points: pre-intervention, one month and eight months post-intervention. On global knowledge of cardiopulmonary resuscitation, there were no significant differences between the intervention group and the control group in the trial pre-intervention and at the month post-intervention. However, at 8 months there were significant differences with a p-value = 0.000 (intervention group, 95% CI: 6.39 to 7.13 vs. control group, 95% CI: 4.75 to 5.92), F(1,120)=16.644, p=0.000). In addition, significant differences about students' basic life support knowledge about chest compressions at eight months post-intervention (F(1,120)=15.561, p=0.000) were found. Our study showed that incorporating the song component in the cardiopulmonary resuscitation teaching increased its effectiveness and the ability to remember the cardiopulmonary resuscitation algorithm. Our study highlights the need for different methods in the cardiopulmonary resuscitation teaching to facilitate knowledge retention and increase the number of positive outcomes after sudden cardiac arrest.

    Current automated external defibrillations require interruptions in chest compressions to avoid artifacts during electrocardiographic analyses and to minimize the risk of accidental delivery of an electric shock to the rescuer. The earlier three-shock algorithm, with prolonged interruptions of chest compressions, compromised outcomes and increased severity of postresuscitation myocardial dysfunction. In the present study, we investigated the effect of timing of minimal automated external defibrillation-mandated interruptions of chest compressions on cardiopulmonary resuscitation outcomes, using a single-shock algorithm. We hypothesized that an 8-sec interruption of chest compressions for a single shock, as mandated by automated external defibrillations, would not impair initial resuscitation and outcomes of cardiopulmonary resuscitation. Randomized prospective animal study. University affiliated research laboratory. Domestic pigs. In 24 domestic male pigs weighing 41 +/- 2 kg, ventricular fibrillation was induced by left anterior descending coronary artery occlusion and untreated for 7 min. Cardiopulmonary resuscitation, including chest compressions and ventilation with oxygen, was then performed for an interval of 2 min before attempted defibrillation. Animals were randomized into three groups: A) interruption immediately before defibrillation; B) interruption after 1 min of cardiopulmonary resuscitation; or C) no interruption. Chest compressions were delivered with the aid of a mechanical chest compressor at a rate of 100 compressions/min and compression/ventilation ratio of 30:2. Defibrillation was attempted with a single biphasic 150-J shock. Each animal was successfully resuscitated and survived for >72 hr. No differences in the number of shocks before return of spontaneous circulation, frequency of recurrent ventricular fibrillation, duration of cardiopulmonary resuscitation, and severity of postresuscitation myocardial dysfunction were observed.

    Tension pneumothorax can occur at any time during cardiopulmonary resuscitation (CPR) with external cardiac massage and invasive ventilation either from primary or iatrogenic rib fractures with concomitant pleural or parenchymal injury. Airway injury can also cause tension pneumothorax during CPR. This article presents the case of a 41-year-old woman who suffered cardiopulmonary arrest after undergoing elective mandibular surgery. During CPR the upper airway could not be secured by orotracheal intubation due to massive craniofacial soft tissue swelling. A surgical airway was established with obviously unrecognized iatrogenic tracheal perforation and subsequent development of tension pneumomediastinum and tension pneumothorax during ventilation. Neither the tension pneumomediastinum nor the tension pneumothorax were decompressed and accordingly resuscitation efforts remained unsuccessful. This case illustrates the need for a structured approach to resuscitate patients with ventilation problems regarding decompression of tension pneumomediastinum and/or tension pneumothorax during CPR.

    1994-09-01

    The cognitions of 20 emergency-physicians while working on a mobile resuscitation unit were examined by means of questionnaire in over 260 situations of resuscitation. A pattern of cognitions could be detected: Emergency physicians appear not to think very much during resuscitation. If there are thoughts, these usually concern the obvious, or what is immediately present in the situation, i.e. the patient or the patient's relatives; repression may also play a role. Cognitions which are reflective of self are rare and only develop late in the situation, depending on the surroundings and the amount of stress. The cognitions concerning the relatives are frequent in those situations with direct physician-relative contact. The physicians often report in retrospect having felt compelled to a decision for resuscitation by the presence of the relatives; nevertheless, the decision itself appears to be a result, rather, of their cognitions of the relatives. Distancing by means of cognition was ubiquitously employed as a coping strategy by physicians when in situations which were perceived as not having a positive outcome. Thoughts about "own death" or "about the patient" are specific, however, for certain groups of doctors. Results of the present investigation suggest that physicians have cognitions about relatives during the process of decision making, and cognitions about the patient during the resuscitation manoeuvre.

    Delayed responses during cardiac arrest are common. Timely interventions during cardiac arrest have a direct impact on patient survival. Integration of technology in nursing education is crucial to enhance teaching effectiveness. The goal of this study was to investigate the effect of animation on nursing students' response time to cardiac arrest, including initiation of timely chest compression. Nursing students were randomized into experimental and control groups prior to practicing in a high-fidelity simulation laboratory. The experimental group was educated, by discussion and animation, about the importance of starting cardiopulmonary resuscitation upon recognizing an unresponsive patient. Afterward, a discussion session allowed students in the experimental group to gain more in-depth knowledge about the most recent changes in the cardiac resuscitation guidelines from the American Heart Association. A linear mixed model was run to investigate differences in time of response between the experimental and control groups while controlling for differences in those with additional degrees, prior code experience, and basic life support certification. The experimental group had a faster response time compared with the control group and initiated timely cardiopulmonary resuscitation upon recognition of deteriorating conditions (P < .0001). The results demonstrated the efficacy of combined teaching modalities for timely cardiopulmonary resuscitation. Providing opportunities for repetitious practice when a patient's condition is deteriorating is crucial for teaching safe practice.

    We wanted to identify incidents that led or could have led to patient harm during prehospital cardiopulmonary resuscitation. A nationwide anonymous and Internet-based critical incident reporting system gave the data. During a 4-year period we received 548 reports of which 74 occurred during cardiopulmonary resuscitation. Human error was responsible for 85% of the incidents, whereas equipment failure contributed to 15% of the reports. Equipment failure was considered to be preventable in 61% of all the cases, whereas incidents because of human error could have been prevented in almost all the cases. In most cases, prevention can be accomplished by simple strategies with the Poka-Yoke technique. Insufficient training of emergency medical service physicians in Germany requires special attention. The critical incident reports raise concerns regarding the level of expertize provided by emergency medical service doctors.

    A 64-year-old man with a history of ascending aortic surgery and pulmonary embolus presented with shortness of breath. He rapidly decompensated, prompting intubation, after which he lost pulses. Manual resuscitation was initiated immediately, with subsequent use of a LUCAS-2 mechanical compression device. The patient was given bolus thrombolytic therapy and regained pulses after 7 min of CPR. Compressions were reinitiated with the LUCAS-2 twice more during resuscitation over the subsequent hour for brief episodes of PEA. After confirmation of massive pulmonary embolism on CT, the patient underwent interventional radiology-guided ultrasonic catheter placement with local thrombolytic therapy and experienced immediate improvement in oxygenation. He later developed abdominal compartment syndrome, despite cessation of thrombolytic and anticoagulation therapy. Bedside exploratory abdominal laparotomy revealed a ruptured subcapsular haematoma of the liver. The patient's haemodynamics improved following surgery and he was extubated 11 days postarrest with intact neurological function.

    Most patients with post-anoxic coma after resuscitation have a poor prognosis. Reliable prediction of poor outcomes (death or vegetative state after 1 month; death, vegetative state or severe disability after at least 6 months) at an early stage is important for both family members and treating physicians. Poor outcome can be predicted with 100% reliability in the first 3 days after resuscitation in about 80% of patients using pupillary and corneal reflexes and motor response from the neurological examination, cortical responses from somatosensory evoked potentials and EEG. The predictive value of a status epilepticus or serum levels of neuron-specific enolase is uncertain at this time. In contrast to poor outcomes, good neurological recovery cannot be predicted reliably at this time.

    Bioavailability of clopidogrel in the form of crushed tablets administered via nasogastric tube (NGT) has not been established in patients after cardiopulmonary resuscitation. Therefore, we performed a study comparing pharmacokinetic and pharmacodynamic response to high loading dose of clopidogrel in critically ill patients after cardiopulmonary resuscitation (CPR) with patients scheduled for elective coronary angiography with stent implantation. In the NGT group (nine patients, after cardiopulmonary resuscitation, mechanically ventilated, therapeutic hypothermia), clopidogrel was administered in the form of crushed tablets via NGT. Ten patients undergoing elective coronary artery stenting took clopidogrel per os (po) in the form of intact tablets. Pharmacokinetics of clopidogrel was measured with high-performance liquid chromatography (HPLC) before and at 0.5, 1, 6, 12, 24 h after administration of a loading dose of 600 mg. In five patients in each group, antiplatelet effect was measured with thrombelastography (TEG; Platelet Mapping) before and 24 h after administration. The carboxylic acid metabolite of clopidogrel was detected in all patients in the po group. In eight patients, the maximum concentration was measured in the range of 0.5-1 h after the initial dose. In four patients in the of NGT group, the carboxylic acid metabolite of clopidogrel was undetectable and in the remaining patients was significantly delayed (peak values at 12 h). All patients in the po group reached clinically relevant (>50 %) inhibition of thrombocyte adenosine diphosphate (ADP) receptor after 24 h compared with only two in the NGT group (p = 0.012). There was a close correlation between peak of inactive clopidogrel metabolite plasmatic concentration and inhibition of the ADP receptor (r = 0.79; p < 0.001). The bioavailability of clopidogrel in critically ill patients after cardiopulmonary resuscitation is significantly impaired compared with stable patients. Therefore

    Mechanical compression of coronary artery stents may be associated with a fatal outcome as the result of refractory myocardial ischemia. We present the history of an 83-yr-old patient, who died owing to hemorrhagic shock 3 days after stent implantation, despite immediate cardiopulmonary resuscitation (CPR). Postmortem examination showed stent compression, probably due to mechanical deformation during CPR. This complication has been reported in two other cases in the literature, suggesting that CPR may be hazardous to patients with coronary artery stents.

    Social laws and religious beliefs throughout history underscore the leaps and bounds that the science of resuscitation has achieved from ancient times until today. The effort to resuscitate victims goes back to ancient history, where death was considered a special form of sleep or an act of God. Biblical accounts of resuscitation attempts are numerous. Resuscitation in the Middle Ages was forbidden, but later during Renaissance, any prohibition against performing cardiopulmonary resuscitation (CPR) was challenged, which finally led to the Enlightenment, where scholars attempted to scientifically solve the problem of sudden death. It was then that the various components of CPR (ventilation, circulation, electricity, and organization of emergency medical services) began to take shape. The 19th century gave way to hallmarks both in the ventilatory support (intubation innovations and the artificial respirator) and the open-and closed chest circulatory support. Meanwhile, novel defibrillation techniques had been employed and ventricular fibrillation described. The groundbreaking discoveries of the 20th century finally led to the scientific framework of CPR. In 1960, mouth-to-mouth resuscitation was eventually combined with chest compression and defibrillation to become CPR as we now know it. This review presents the scientific milestones behind one of medicine's most widely used fields.

    BACKGROUND: Because most cardiac arrests occur at home, widespread training is needed to increase the incidence of cardiopulmonary resuscitation (CPR) by lay persons. The aim of this study was to evaluate the effect of mass distribution of CPR instructional materials among schoolchildren. METHODS...... the project did not increase significantly compared with the previous year (25.0% versus 27.9%; P=0.16). CONCLUSIONS: CPR training can be disseminated in a population by distributing personal resuscitation manikins among children in primary schools. The teachers felt able to easily facilitate CPR training...... AND RESULTS: We distributed 35,002 resuscitation manikins to pupils (12 to 14 years of age) at 806 primary schools. Using the enclosed 24-minute instructional DVD, they trained in CPR and subsequently used the kit to train family and friends (second tier). They completed a questionnaire on who had trained...

    Cardiopulmonary resuscitation manikins are used for training personnel in performing cardiopulmonary resuscitation. State-of-the-art cardiopulmonary resuscitation manikins are still anatomically and physiologically low-fidelity designs. The aim of this research was to design a manikin that offers high anatomical and physiological fidelity and has a cardiac and respiratory system along with integrated flow sensors to monitor cardiac output and air displacement in response to cardiopulmonary resuscitation. This manikin was designed in accordance with anatomical dimensions using a polyoxymethylene rib cage connected to a vertebral column from an anatomical female model. The respiratory system was composed of silicon-coated memory foam mimicking lungs, a polyvinylchloride bronchus and a latex trachea. The cardiovascular system was composed of two sets of latex tubing representing the pulmonary and aortic arteries which were connected to latex balloons mimicking the ventricles and lumped abdominal volumes, respectively. These balloons were filled with Life/form simulation blood and placed inside polyether foam. The respiratory and cardiovascular systems were equipped with flow sensors to gather data in response to chest compressions. Three non-medical professionals performed chest compressions on this manikin yielding data corresponding to force-displacement while the flow sensors provided feedback. The force-displacement tests on this manikin show a desirable nonlinear behaviour mimicking chest compressions during cardiopulmonary resuscitation in humans. In addition, the flow sensors provide valuable data on the internal effects of cardiopulmonary resuscitation. In conclusion, scientifically designed and anatomically high-fidelity designs of cardiopulmonary resuscitation manikins that embed flow sensors can improve physiological fidelity and provide useful feedback data.

    2004-01-01

    INTRODUCTION: The International Space Station will need to be as capable as possible in providing Advanced Cardiac Life Support (ACLS) and cardiopulmonary resuscitation (CPR). Previous studies with manikins in parabolic microgravity (0 G) have shown that delivering CPR in microgravity is difficult. End tidal carbon dioxide (PetCO2) has been previously shown to be an effective non-invasive tool for estimating cardiac output during cardiopulmonary resuscitation. Animal models have shown that this diagnostic adjunct can be used as a predictor of survival when PetCO2 values are maintained above 25% of pre-arrest values. METHODS: Eleven anesthetized Yorkshire swine were flown in microgravity during parabolic flight. Physiologic parameters, including PetCO2, were monitored. Standard ACLS protocols were used to resuscitate these models after chemical induction of cardiac arrest. Chest compressions were administered using conventional body positioning with waist restraint and unconventional vertical-inverted body positioning. RESULTS: PetCO2 values were maintained above 25% of both 1-G and O-G pre-arrest values in the microgravity environment (33% +/- 3 and 41 +/- 3). No significant difference between 1-G CPR and O-G CPR was found in these animal models. Effective CPR was delivered in both body positions although conventional body positioning was found to be quickly fatiguing as compared with the vertical-inverted. CONCLUSIONS: Cardiopulmonary resuscitation can be effectively administered in microgravity (0 G). Validation of this model has demonstrated that PetCO2 levels were maintained above a level previously reported to be predictive of survival. The unconventional vertical-inverted position provided effective CPR and was less fatiguing as compared with the conventional body position with waist restraints.

    Full Text Available Introduction: A high leve of skill & knowledge is required in circumstances of cardiopulmonary resucitation which represents the most urgent clinical situations. The difficulties for pediatric residents who are fronted with the most cases of pediatric & neonatal resucitation are due to different causes of cardiorespiratory arrest in camparison to adults. This study aimed to assess the knowledge & their personal attitude toward the neonatal & pediatric cardiopulmonary resuscitatin. Methods: By cross - sectional multicenter study between the pediatric residents who were studied in the teaching hospitals in Tehran (1378-90. Data were gathered among 140 residents by self-completed questionnaires which were included three parts as. demographic information assessment of their attitude by summation of score via ranking list questions and total score from assessment to their knowledge by different scenarios which were formatted in the multiple choice questions. Results: 35.7% of the residents studied in the first year of residency 35.0% in the second year and the remainder (29/3% in the third year More than 90% of them considered their knowledge about neonatal and pediatric cardiopulmonary resuscitation low & less than average. Net only 80% of the residents self - assessed their actual ability about this issue low but also declaired the insufficient education during the medical training. The total score of knowledge assessment was 14.7 + 1_0.54 from 30 without any significant relations among the residents in different hospitals or various levels of pediatric residency. (P value= 0.1 , 0.7 There was not significant correlation between the total score from their attitude & their knowledge. Conclusion: Pediatric residents as the key personnel in the management of cardiopulmonary resuscitation of the neonates and children should have enough knowledge and skills about this topic.

    Post-resuscitation myocardial dysfunction is an important cause of death in the intensive care unit after initially successful cardiopulmonary resuscitation (CPR) of pre-hospital cardiac arrest (CA) patients. Volatile anaesthetics reduce ischaemic-reperfusion injury in regional ischaemia in beating hearts. This effect, called anaesthetic-induced pre- or postconditioning, can be shown when the volatile anaesthetic is given either before regional ischaemia or in the reperfusion phase. However, up to now, little data exist for volatile anaesthetics after global ischaemia due to CA. Therefore, the goal of this study was to clarify whether Sevoflurane improves post-resuscitation myocardial dysfunction after CA in rats. Following institutional approval by the Governmental Animal Care Committee, 144 male Wistar rats (341±19g) were randomized either to a control group or to one of the 9 interventional groups receiving 0.25 MAC, 0.5 MAC or 1 MAC of Sevoflurane for 5min either before resuscitation (SBR), during resuscitation (SDR) or after resuscitation (SAR). After 6min of electrically induced ventricular fibrillation CPR was performed. Before CA (baseline) as well as 1h and 24h after restoration of spontaneous circulation (ROSC), continuous measurement of ejection fraction (EF), and preload adjusted maximum power (PAMP) as primary outcome parameters and end systolic pressure (ESP), end diastolic volume (EDV) and maximal slope of systolic pressure increment (dP/dtmax) as secondary outcome parameters was performed using a conductance catheter. EF was improved in all Sevoflurane treated groups 1h after ROSC in comparison to control, except for the 0.25 MAC SDR and 0.25 MAC SAR group (0.25 MAC SBR: 38±8, p=0.02; 0.5 MAC SBR: 39±7, p=0.04; 1 MAC SBR: 40±6, p=0.007; 0.5 MAC SDR: 38±7, p=0.02; 1 MAC SDR: 40±6, p=0.006; 0.5 MAC SAR: 39±6, p=0.01; 1 MAC SAR: 39±6, p=0.002, vs. 30±7%). Twenty-four hours after ROSC, EF was higher than control in all interventional groups

    To determine the outcome of apparently stillborn infants who received cardiopulmonary resuscitation, we studied the short- and long-term outcome of 93 infants who had an Apgar score of 0 at 1 minute of age and were resuscitated at birth. Sixty-two (66.6%) responded and left the delivery room alive; 26 (42%) of the 62 infants died in the neonatal period and 36 infants were discharged home; of the 36 infants, three subsequently died during infancy. Of the 33 survivors, ten were lost to follow-up after discharge. Developmental assessment of 23 of 33 long-term survivors revealed normal outcome in 14 (61.7%), abnormal results in 6 (26%), and suspect status in 3 (13%). Fifty-eight infants had an Apgar score of 0 at greater than or equal to 10 minutes of age and all except one died; the surviving infant has an abnormal developmental outcome. We conclude that 39% of apparently stillborn infants who were resuscitated survived beyond the neonatal period and that 61% of the 23 survivors who were available for developmental follow-up had normal development at the time of last examination. Survival was unlikely if there was no response after 10 minutes of resuscitation.

    The administration of cardiopulmonary resuscitation (CPR) was taught to a group of 12 adults. The Tennessee Self-concept Scale Form-C and the Fundamental Interpersonal Relations Orientation-Behavior Scale (FIRO-B) were administered before and after their training. A control group of 12 was administered both scales twice with one day between administrations. Analysis indicated both groups showed significant differences between the pre- and posttest administrations on expressed affection on the FIRO-B. However, participants in a brief CPR course did not score significantly differently from a control group on these measures, as expected.

    A report of a 62-year-old female patient with severe Mallory-Weiss syndrome after successful cardiopulmonary resuscitation (CPR) by health care providers in the emergency department is presented. The bleeding continued for five days, and the patient’s total blood loss was estimated to be approximately 3 000 mL. After 7 days, the patient died due to respiratory distress syndrome. Severe Mallory-Weiss syndrome afterCPR may occur and should be considered as a potentially serious complication afterCPR.

    Empirical evidence suggests that family presence during cardiopulmonary resuscitation (CPR) has beneficial effects. Although many American professional organizations have endorsed the idea of family presence, there is less formal support in Europe. In addition, the attitude of nurses from Anglo-Saxon countries, such as United Kingdom and Ireland, is more positive toward family presence than the attitude of nurses of mainland Europe. In order to support existing guidelines and to stimulate health care organizations to develop a formal policy with respect to family witnessed CPR, 3 important European nursing organizations have recently developed a joint position statement.

    Dose calculations using three variations of patient weight estimates (actual body weight [ABW], ideal body weight [IBW], and the Broselow Pediatric Emergency Tape [BPET, a length-based weight estimation tool]) were compared to administered doses of cardiopulmonary resuscitation medications in overweight and obese children to assess for differences in dose. This retrospective cohort analysis included 54 consecutive pediatric patients who underwent emergency resuscitation at UMass Memorial Medical Center between January 2000 and October 2008. Patients were identified using ICD-9 codes related to cardiopulmonary resuscitation. Patients were included if they were overweight or obese, less than 12 years of age, less than 146 centimeters in length, and received emergency resuscitation medication(s). Doses of administered medications were recorded and compared to potential doses calculated based on ABW, IBW and the dose recommended by the BPET. Dose differences greater than 10% were considered clinically significant and dose differences greater than 20% were considered to be potential medication errors. Out of 54 possible patients, four overweight patients were included; none were obese. Ten total medication doses were assessed (minimum two per patient). In all patients, at least one comparator dose varied by greater than 20% from the administered dose. Four out of 10 doses calculated according to ABW, eight out of 10 doses calculated with IBW, and eight out of 10 doses recommended by the BPET all differed by greater than 20% from the administered dose. Dosing variations were observed when the dose received was compared to dosing using three variants of patient weight estimates. The largest dosing differences were observed upon comparison of the administered dose versus the dose recommended by the BPET.

Methods: In this prospective interventional study, pa-tients presenting with PEA cardiac arrest were randomized into two groups. In Group A, ultrasound trained emergency physicians performed echocardiography evaluating cardiac activity, right ventricle dilation, left ventricle function, peri-cardial effusion/tamponade and IVC size along with the ad-vanced cardiac life support (ACLS protocol. Patients in Group B solely underwent ACLS protocol without applying echocardiography. The presence or absence of mechanical ventricular activity (MVA and evidences of PEA reversible causes were recorded. The return of spontaneous circulation (ROSC and death were evaluated in both groups. Results: One hundred patients with the mean age of (58±6.1 years were enrolled in this study. Fifty patients (Group A had echocardiography detected in parallel with cardiopulmonary resuscitation (CPR. Among them, 7 pa-tients (14% had pericardial effusion, 11 (22% had hypovolemia, and 39 (78% were revealed the presence of MVA. In the pseudo PEA subgroup (presence of MVA, 43% had ROSC (positive predictive value and in the true PEA subgroup with cardiac standstill (absence of MVA, there was no recorded ROSC (negative predictive value. Among patients in Group B, no reversible etiology was detected. There was no significant difference in resuscitation results between Groups A and B observed (P=0.52. Conclusion: Bedside echocardiography can identify some reversible causes of PEA. However, there are no sig-nificant changes in survival outcome between the echo group and those with traditional CPR.

    OBJECTIVE: to analyze determinant factors for the immediate survival of persons who receive cardiopulmonary resuscitation from the advanced support units of the Mobile Emergency Medical Services (SAMU) of Belo Horizonte. METHOD: this is a retrospective, epidemiological study which analyzed 1,165 assistance forms, from the period 2008 - 2010. The collected data followed the Utstein style, being submitted to descriptive and analytical statistics with tests with levels of significance of 5%. RESULTS: the majority were male, the median age was 64 years, and the ambulance response time, nine minutes. Immediate survival was observed in 239 persons. An association was ascertained of this outcome with "cardiac arrest witnessed by persons trained in basic life support" (OR=3.49; p<0.05; CI 95%), "cardiac arrest witnessed by Mobile Emergency Medical Services teams" (OR=2.99; p<0.05; CI95%), "only the carry out of basic life support" (OR=0.142; p<0.05; CI95%), and "initial cardiac rhythm of asystole" (OR=0.33; p<0.05; CI 95%). CONCLUSION: early access to cardiopulmonary resuscitation was related to a favorable outcome, and the non-undertaking of advanced support, and asystole, were associated with worse outcomes. Basic and advanced life support techniques can alter survival in the event of cardiac arrest. PMID:25296138

    Cardiopulmonary resuscitation rates and survival from out-of-hospital cardiac arrest are poor in the UK compared with areas abroad that deliver mandatory training to all school children. We sought to identify barriers to training and develop a strategy to enable delivery of this training. Qualitative analysis, comprising semistructured interviews and group discussions, covering 14 schools in the metropolitan borough of Calderdale in West Yorkshire. Only three schools out of 14 were delivering training to entire year groups. Barriers include lack of resources, lack of training for teachers and difficulty in initiating a programme. Strategies were developed to overcome these barriers with the result that four additional schools are now teaching a whole year group. There is no single solution and bespoke plans may be needed for each school. The establishment of cardiopulmonary resuscitation training in secondary schools in the UK is achievable. The commonly perceived barriers to establishment of training are all surmountable, but solving them does not necessarily ensure universal coverage. Support from healthcare professionals, in particular public health, is essential to ensure that the training is as widespread as possible. Mandatory inclusion of this training on the school curriculum, as seen in other countries, would result in significantly improved survival rates from out-of-hospital cardiorespiratory arrest. Solutions to improve training have been proposed, which could be used in other parts of Europe where such training is not a mandatory requirement.

  1. Marginally effective medical care: ethical analysis of issues in cardiopulmonary resuscitation (CPR)

    Hilberman, M; Kutner, J; Parsons, D; Murphy, D J

    1997-12-01

    Outcomes from cardiopulmonary resuscitation (CPR) remain distressingly poor. Overuse of CPR is attributable to unrealistic expectations, unintended consequences of existing policies and failure to honour patient refusal of CPR. We analyzed the CPR outcomes literature using the bioethical principles of beneficence, non-maleficence, autonomy and justice and developed a proposal for selective use of CPR. Beneficence supports use of CPR when most effective. Non-maleficence argues against performing CPR when the outcomes are harmful or usage inappropriate. Additionally, policies which usurp good clinical judgment and moral responsibility, thereby contributing to inappropriate CPR usage, should be considered maleficent. Autonomy restricts CPR use when refused but cannot create a right to CPR. Justice requires that we define which medical interventions contribute sufficiently to health and happiness that they should be made universally available. This ordering is necessary whether one believes in the utilitarian standard or wishes medical care to be universally available on fairness grounds. Low-yield CPR fails justice criteria. Cardiopulmonary resuscitation should be performed when justified by the extensive outcomes literature; not performed when not desired by the patient or not indicated; and performed infrequently when relatively contraindicated.

The maneuvers of basic resuscitation are easy to realise, any person can learn them and she does not need specific equipment.The sanitary professionals we are convinced of the prevention through the education and the basic formation of the population before situations critics. Starting off of these premises, our work group considers that the diffusion and education of the knowledge and abilities of the basic CPR between the general population are one of the main methods to improve the rates of survival and to diminish sequels.Our course of CPR is theoretical-practical is directed to parents of children with cardiac, pulmonary, neurological problems at the risk of suffering episodes of vital commitment. Its purpose is that the students secure to resuscitation abilities and action criteria. The theoretical part has as objectives to facilitate the decision making and the understanding of the maneuvers. The practical part consists of the sequential repetition of the maneuvers to practice the coordination and the abilities before diverse situations that can be found the parents.

    Multiple interventions have been tested in models of cardiopulmonary resuscitation (CPR) to optimize drug use, chest compressions, and ventilation. None has studied the effects of positive end-expiratory pressure (PEEP) on outcome. We hypothesized that because PEEP can reverse pulmonary atelectasis, lower pulmonary vascular resistance, and potentially improve cardiac output, its use during CPR would increase survival.

    Advanced cardiovascular life support guidelines exist, yet there are variations in clinical practice. Our study aims to describe the utilization of medications during resuscitation from in-hospital cardiopulmonary arrest. A retrospective review of patients who suffered a cardiopulmonary arrest from May 2008 to June 2014 was performed. Clinical and resuscitation data, including timing and dose of medications used, were extracted from the electronic medical record and comparisons made. A total of 94 patients were included in the study. Patients were divided into different groups based on the medication combination used during resuscitation: (1) epinephrine; (2) epinephrine and bicarbonate; (3) epinephrine, bicarbonate, and calcium; (4) epinephrine, bicarbonate, and epinephrine drip; and (5) epinephrine, bicarbonate, calcium, and epinephrine drip. No difference in baseline demographics or clinical data was present, apart from history of dementia and the use of calcium channel blockers. The number of medications given was correlated with resuscitation duration (Spearman's rank correlation = 0.50, p <0.001). The proportion of patients who died during the arrest was 12.5% in those who received epinephrine alone, 30.0% in those who received only epinephrine and bicarbonate, and 46.7% to 57.9% in the remaining groups. Patients receiving only epinephrine had shorter resuscitation durations compared to that of the other groups (p <0.001) and improved survival (p = 0.003). In conclusion, providers frequently use nonguideline medications in resuscitation efforts for in-hospital cardiopulmonary arrests. Increased duration and mortality rates were found in those resuscitations compared with epinephrine alone, likely due to the longer resuscitation duration in the former groups.

    Cardiopulmonary resuscitation in patients with severe sepsis and septic shock is challenging and usually unsuccessful. The aim of the present study is to describe our swine model of cardiac arrest and resuscitation in severe sepsis and septic shock. In this prospective randomized animal study, 10 healthy female Landrace-Large White pigs with an average weight of 20 ± 1 kg (aged 19 - 21 weeks) were the study subjects. Septicemia was induced by an intravenous infusion of a bolus of 20-mL bacterial suspension in 2 min, followed by a continuous infusion during the rest of the experiment. After septic shock was confirmed, the animals were left untreated until cardiac arrest occurred. All animals developed pulseless electrical activity between the fifth and sixth hours of septicemia, whereas five (50%) of 10 animals were successfully resuscitated. Coronary perfusion pressure was statistically significantly different between surviving and nonsurviving animals. We found a statistically significant correlation between mean arterial pressure and unsuccessful resuscitation (P = 0.046), whereas there was no difference in end-tidal carbon dioxide (23.05 ± 1.73 vs. 23.56 ± 1.70; P = 0.735) between animals with return of spontaneous circulation and nonsurviving animals. During the 45-min postresuscitation monitoring, we noted a significant decrease in hemodynamic parameters, although oxygenation indices and lactate clearance were constantly increased (P = 0.001). This successful basic swine model was for the first time developed and may prove extremely useful in future studies on the periarrest period in severe sepsis and septic shock.

    This randomized controlled trial, conducted in a UK University nursing department, compared student nurses' performance during a simulated cardiac arrest. Eighteen teams of four students were randomly assigned to one of three scenarios: 1) no family witness; 2) a "quiet" family witness; and 3) a family witness displaying overt anxiety and distress. Each group was assessed by observers for a range of performance outcomes (e.g. calling for help, timing to starting cardiopulmonary resuscitation), and simulation manikin data on the depth and timing of three cycles of compressions. Groups without a distressed family member present performed better in the early part of the basic life support algorithm. Approximately a third of compressions assessed were of appropriate pressure. Groups with a distressed family member present were more likely to perform compressions with low pressure. Groups with no family member present were more likely to perform compressions with too much pressure. Timing of compressions was better when there was no family member present. Family presence appears to have an effect on subjectively and objectively measured performance. Further study is required to see how these findings translate into the registered nurse population, and how experience and education modify the impact of family member presence.

    2013-01-01

    Full Text Available Various filtering strategies have been adopted and investigated to suppress the cardiopulmonary resuscitation (CPR artifact. In this article, two types of artifact removal methods are reviewed: one is the method that removes CPR artifact using only ECG signals, and the other is the method with additional reference signals, such as acceleration, compression depth and transthoracic impedance. After filtering, the signal-to-noise ratio is improved from 0 dB to greater than 2.8 dB, the sensitivity is increased to > 90% as recommended by the American Heart Association, whereas the specificity was far from the recommended 95%, which is considered to be the major drawback of the available artifact removal methods. The overall performance of the adaptive filtering methods with additional reference signal outperforms the methods using only ECG signals. Further research should focus on the refinement of artifact filtering methods and the improvement of shock advice algorithms with the presence of CPR.

    BACKGROUND: Initiation of early bystander cardiopulmonary resuscitation (CPR) depends on bystanders' or medical dispatchers' recognition of out-of-hospital cardiac arrest (OHCA). The primary aim of our study was to investigate if OHCA recognition during the emergency call was associated...... with bystander CPR, return of spontaneous circulation (ROSC), and 30-day survival. Our secondary aim was to identify patient-, setting-, and dispatcher-related predictors of OHCA recognition. METHODS: We performed an observational study of all OHCA patients' emergency calls in the Capital Region of Denmark from...... the association between OHCA recognition and bystander CPR, ROSC, and 30-day survival. Univariable logistic regression analyses were applied to identify predictors of OHCA recognition. RESULTS: We included 779 emergency calls in the analyses. During the emergency calls, 70.1% (n=534) of OHCAs were recognised...

    Early defibrillation in cardiopulmonary resuscitation (CPR) receives increasing emphasis on its priority and rapidity. This is an experience report about the implementation of a training program in CPR using a defibrillator in a private university. The training program in basic CPR maneuvers was based on global guidelines, including a theorical course with practical demonstration of CPR maneuvers with the defibrillator, individual practical training and theoretical and practical assessments. About the performance of students in the practical assessment the mean scores obtained by students in the first stage of the course was 26.4 points, while in the second stage the mean was 252.8 points, in the theoretical assessment the mean in the first stage was 3.06 points and in the second 9.0 points. The implementation of programs like this contribute to the effective acquisition of knowledge (theory) and skill (pratice) for the care of CPR victims.

    Cardiac arrest (CA) patients can experience neurological sequelae or even death after successful cardiopulmonary resuscitation (CPR) due to cerebral hypoxia- and ischemia-reperfusion-mediated brain injury. Thus, it is important to perform early prognostic evaluations in CA patients. Electroencephalography (EEG) is an important tool for determining the prognosis of hypoxic-ischemic encephalopathy due to its real-time measurement of brain function. Based on EEG, burst suppression, a burst suppression ratio >0.239, periodic discharges, status epilepticus, stimulus-induced rhythmic, periodic or ictal discharges, non-reactive EEG, and the BIS value based on quantitative EEG may be associated with the prognosis of CA after successful CPR. As measures of neural network integrity, the values of small-world characteristics of the neural network derived from EEG patterns have potential applications.

    Survival rates after out-of-hospital cardiac arrest (OHCA) vary considerably among regions. The chance of survival is increased significantly by lay rescuer cardiopulmonary resuscitation (CPR) before Emergency Medical Services (EMS) arrival. It is well known that for bystanders, reasons for not providing CPR when witnessing an OHCA incident may be fear and the feeling of being exposed to risk. The aim of this study was to gain a better understanding of why barriers to providing CPR are overcome. Using a semi-structured interview guide, 10 lay rescuers were interviewed after participating in eight OHCA incidents. Qualitative content analysis was used. The lay rescuers were questioned about their CPR-knowledge, expectations, and reactions to the EMS and from others involved in the OHCA incident. They also were questioned about attitudes towards providing CPR in an OHCA incident in different contexts. The lay rescuers reported that they were prepared to provide CPR to anybody, anywhere. Comprehending the severity in the OHCA incident, both trained and untrained lay rescuers provided CPR. They considered CPR provision to be the expected behavior of any community citizen and the EMS to act professionally and urgently. However, when asked to imagine an OHCA in an unclear setting, they revealed hesitation about providing CPR because of risk to their own safety. Mutual trust between community citizens and towards social institutions may be reasons for overcoming barriers in providing CPR by lay rescuers. A normative obligation to act, regardless of CPR training and, importantly, without facing any adverse legal reactions, also seems to be an important factor behind CPR provision.

    To determine the relationship between acid-base findings, such as pH, pCO2, and serum lactate levels, obtained immediately after starting cardiopulmonary resuscitation and the return of spontaneous circulation (ROSC).A prospective observational study of adult, nontraumatic out-of-hospital cardiac arrest (OHCA) patients was conducted at an urban academic teaching institution between April 1, 2013 and March 31, 2015. Arterial blood sample for acid-base data was taken from all OHCA patients on arrival to the emergency department. Of 224 OHCA patients, 88 patients with unavailable blood samples or delayed blood sampling or ROSC within 4 minutes were excluded, leaving 136 patients for analysis.The pH in the ROSC group was significantly higher than in the non-ROSC group (6.96 vs. 6.85; P = 0.009). pCO2 and lactate levels in the ROSC group were significantly lower than those in the non-ROSC group (74.0 vs. 89.5 mmHg, P < 0.009; 11.6 vs. 13.6 mmol/L, P = 0.044, respectively). In a multivariate regression analysis, pCO2 was the only independent biochemical predictor for sustained ROSC (OR 0.979; 95% CI 0.960-0.997; P = 0.025) and pCO2 of <75 mmHg was 3.3 times more likely to achieve ROSC (OR 0.302; 95% CI 0.146-0.627; P = 0.001).pCO2 levels obtained during cardiopulmonary resuscitation on ER arrival was associated with ROSC in OHCA patients. It might be a potentially marker for reflecting the status of the ischemic insult. These preliminary results need to be confirmed in a larger population.

    2009-07-01

    Full Text Available Abstract Background Hands-Only cardiopulmonary resuscitation (CPR is recommended for use on adult victims of witnessed out-of-hospital (OOH sudden cardiac arrest or in instances where rescuers cannot perform ventilations while maintaining minimally interrupted quality compressions. Promotion of Hands-Only CPR should improve the incidence of bystander CPR and, subsequently, survival from OOH cardiac arrest; but, little is known about a rescuer's ability to deliver continuous chest compressions of adequate rate and depth for periods typical of emergency services response time. This study evaluated chest compression rate and depth as subjects performed Hands-Only CPR for 10 minutes. For comparison purposes, each also performed chest compressions with ventilations (30:2 CPR. It also evaluated fatigue and changes in body biomechanics associated with each type of CPR. Methods Twenty healthy female volunteers certified in basic life support performed Hands-Only CPR and 30:2 CPR on a manikin. A mixed model repeated measures cross-over design evaluated chest compression rate and depth, changes in fatigue (chest compression force, perceived exertion, and blood lactate level, and changes in electromyography and joint kinetics and kinematics. Results All subjects completed 10 minutes of 30:2 CPR; but, only 17 completed 10 minutes of Hands-Only CPR. Rate, average depth, percentage at least 38 millimeters deep, and force of compressions were significantly lower in Hands-Only CPR than in 30:2 CPR. Rates were maintained; but, compression depth and force declined significantly from beginning to end CPR with most decrement occurring in the first two minutes. Perceived effort and joint torque changes were significantly greater in Hands-Only CPR. Performance was not influenced by age. Conclusion Hands-Only CPR required greater effort and was harder to sustain than 30:2 CPR. It is not known whether the observed greater decrement in chest compression depth associated

    To describe the design and to present the results of a paediatric and neonatal cardiopulmonary resuscitation (CPR) training program adapted to Latin-America. A paediatric CPR coordinated training project was set up in several Latin-American countries with the instructional and scientific support of the Spanish Group for Paediatric and Neonatal CPR. The program was divided into four phases: CPR training and preparation of instructors; training for instructors; supervised teaching; and independent teaching. Instructors from each country participated in the development of the next group in the following country. Paediatric Basic Life Support (BLS), Paediatric Intermediate (ILS) and Paediatric Advanced (ALS) courses were organized in each country adapted to local characteristics. Five Paediatric Resuscitation groups were created sequentially in Honduras (2), Guatemala, Dominican Republican and Mexico. During 5 years, 6 instructors courses (94 students), 64 Paediatric BLS Courses (1409 students), 29 Paediatrics ILS courses (626 students) and 89 Paediatric ALS courses (1804 students) were given. At the end of the program all five groups are autonomous and organize their own instructor courses. Training of autonomous Paediatric CPR groups with the collaboration and scientific assessment of an expert group is a good model program to develop Paediatric CPR training in low- and middle income countries. Participation of groups of different countries in the educational activities is an important method to establish a cooperation network.

    Full Text Available Cardiopulmonary resuscitation (CPR is a first-aid key survival technique used to stimulate breathing and keep blood flowing to the heart. Its effective administration can significantly increase the survival chances of cardiac arrest victims. We propose 30 : 2, a videogame designed to introduce the main steps of the CPR protocol. It is not intended for certification and training purpose. Driven by the 2010 European Resuscitation Council guidelines we have designed a game composed of eight mini games corresponding to the main steps of the protocol. The player acts as a helper and has to solve a different challenge. We present a detailed description of the game creation process presenting the requirements, the design decisions, and the implementation details. In addition, we present some first impressions of our testing users (25 children, five of each age from 8 to 12 years old and 12 males and 13 females. We evaluated clarity of instructions and three settings of the game: the aesthetics of scenarios, the playability, and the enjoyability of each mini game. All games were well punctuated, and there are no significantly differences between their sex. The proposed game can be a suitable tool to disseminate and promote CPR knowledge.

    2015-01-01

    To review UK newspaper reports relating to Do Not Attempt Cardiopulmonary Resuscitation (DNACPR) decisions in order to identify common themes and encourage dialogue. An online media database (LexisNexis(®)) was searched for UK Newspaper articles between 1993 and 2013 that referenced DNACPR decisions. Legal cases, concerning resuscitation decisions, were identified using two case law databases (Lexis Law(®) and Westlaw(®)), and referenced back to newspaper publications. All articles were fully reviewed. Three hundred and thirty one articles were identified, resulting from 77 identifiable incidents. The periods 2000-01 and 2011-13 encompassed the majority of articles. There were 16 high-profile legal cases, nine of which resulted in newspaper articles. Approximately 35 percent of newspaper reports referred to DNACPR decisions apparently made without adequate patient and/or family consultation. "Ageism" was referred to in 9 percent of articles (mostly printed 2000-02); and "discrimination against the disabled" in 8 percent (mostly from 2010-12). Only five newspaper articles (2 percent) discussed patients receiving CPR against their wishes. Eighteen newspaper reports (5 percent) associated DNACPR decisions with active euthanasia. Regarding DNACPR decision-making, the predominant theme was perceived lack of patient involvement, and, more recently, lack of surrogate involvement. Negative language was common, especially when decisions were presumed unilateral. Increased dialogue, and shared decision-making, is recommended. Copyright © 2014 Elsevier Ireland Ltd.

    2014-07-01

    Full Text Available Introduction: The purpose of this study was to determine cardiopulmonary resuscitation (CPR knowledge of hospital providers and whether knowledge affects performance of effective compressions during a simulated cardiac arrest. Methods: This cross-sectional study evaluated the CPR knowledge and performance of medical students and ED personnel with current CPR certification. We collected data regarding compression rate, hand placement, depth, and recoil via a questionnaire to determine knowledge, and then we assessed performance using 60 seconds of compressions on a simulation mannequin. Results: Data from 200 enrollments were analyzed by evaluators blinded to subject knowledge. Regarding knowledge, 94% of participants correctly identified parameters for rate, 58% for hand placement, 74% for depth, and 94% for recoil. Participants identifying an effective rate of ≥100 performed compressions at a significantly higher rate than participants identifying <100 (µ=117 vs. 94, p<0.001. Participants identifying correct hand placement performed significantly more compressions adherent to guidelines than those identifying incorrect placement (µ=86% vs. 72%, p<0.01. No significant differences were found in depth or recoil performance based on knowledge of guidelines. Conclusion: Knowledge of guidelines was variable; however, CPR knowledge significantly impacted certain aspects of performance, namely rate and hand placement, whereas depth and recoil were not affected. Depth of compressions was poor regardless of prior knowledge, and knowledge did not correlate with recoil performance. Overall performance was suboptimal and additional training may be needed to ensure consistent, effective performance and therefore better outcomes after cardiopulmonary arrest.

    Full Text Available Abstract OBJECTIVE To identify, in the perception of nurses, the factors that affect the quality of cardiopulmonary resuscitation (CPR in adult inpatient units, and investigate the influence of both work shifts and professional experience length of time in the perception of these factors. METHOD A descriptive, exploratory study conducted at a hospital specialized in cardiology and pneumology with the application of a questionnaire to 49 nurses working in inpatient units. RESULTS The majority of nurses reported that the high number of professionals in the scenario (75.5%, the lack of harmony (77.6% or stress of any member of staff (67.3%, lack of material and/or equipment failure (57.1%, lack of familiarity with the emergency trolleys (98.0% and presence of family members at the beginning of the cardiopulmonary arrest assistance (57.1% are factors that adversely affect the quality of care provided during CPR. Professional experience length of time and the shift of nurses did not influence the perception of these factors. CONCLUSION The identification of factors that affect the quality of CPR in the perception of nurses serves as parameter to implement improvements and training of the staff working in inpatient units.

    Objective The aim of this study was to evaluate the relative frequency of pediatric in-hospital CPR events occurring in intensive care units (ICUs) compared to general wards. We hypothesized that the proportion of pediatric CPR provided in ICUs versus general wards has increased over the past decade and this shift is associated with improved resuscitation outcomes. Design Prospective, observational study. Setting Total of 315 hospitals in the American Heart Association’s Get With The Guidelines-Resuscitation (GTWG-R) database. Patients Total of 5,870 pediatric cardiopulmonary resuscitation (CPR) events between January 1, 2000 and September 14, 2010. CPR events were defined as external chest compressions >1minute. Measurements and Results The primary outcome was proportion of total ICU versus general ward CPR events over time evaluated by chi square test for trend. Secondary outcome included return of spontaneous circulation (ROSC) following the CPR event. Among 5870 pediatric CPR events, 5477 (93.3%) occurred in ICUs compared to 393 (6.7%) on inpatient wards. Over time, significantly more of these CPR events occurred in the ICU compared to the wards (test for trend: p<0.01), with a prominent shift noted between 2003 and 2004 (2000-2003: 87 - 91% vs. 2004-2010: 94 - 96%). In a multivariable model controlling for within center variability and other potential confounders, ROSC increased in 2004-2010 compared with 2000-2003 (RR 1.08, 95% confidence interval: 1.03-1.13). Conclusions In-hospital pediatric CPR is much more commonly provided in ICUs vs. Wards and the proportion has increased significantly over the past decade with concomitant increases in return of spontaneous circulation.

    Counseling patients about the risks and benefits of in-hospital cardiopulmonary resuscitation (CPR) can potentially reduce patient suffering and hospital costs. However, there is currently much disagreement regarding the overall rate of in-hospital CPR survival and characteristics that identify patients more or less likely to survive CPR. The charts of all adults who were pulseless and received basic CPR at a 720-bed university hospital during 1990 and 1991 were reviewed. Patients were excluded if cardiac arrest occurred outside the hospital or in the emergency department, operating room, recovery room, or cardiac catheterization laboratory. Each patient's chart was reviewed to determine the presence of explicitly defined clinical characteristics. Overall, 50 (16.0%) of 313 patients survived to discharge. Before arrest, only impaired functional capacity and sepsis identified patients unlikely to survive CPR. Of adults suffering cardiac arrest during the study period, only 22% underwent CPR, including 13.0% of those with cancer and 18.1% of those 70 years or older. The use of do-not-resuscitate orders to exclude patients who were inappropriate candidates for CPR may explain why the survival rate reported here is higher than similar reports and why more clinical characteristics were not found to predict CPR survival. Investigators of in-hospital CPR should use explicit criteria to describe the conditions studied and report survival for patients who receive basic CPR. The impact of do-not-resuscitate orders on survival rates must be considered. Functional capacity deserves further investigation as a predictor of CPR survival.

    Objective: To examine the utility of bedside echocardiography in detecting the reversible causes of pulseless electrical activity (PEA) cardiac arrest and predicting the resuscitation outcomes.Methods: In this prospective interventional study,patients presenting with PEA cardiac arrest were randomized into two groups.In Group A,ultrasound trained emergency physicians performed echocardiography evaluating cardiac activity,right ventricle dilation,left ventricle function,pericardial effusion/tamponade and ⅣC size along with the advanced cardiac life support (ACLS) protocol.Patients in Group B solely underwent ACLS protocol without applying echocardiography.The presence or absence of mechanical ventricular activity (MVA) and evidences of PEA reversible causes were recorded.The return of spontaneous circulation (ROSC) and death were evaluated in both groups.Results: One hundred patients with the mean age of (58±6.1) years were enrolled in this study.Fifty patients (Group A) had echocardiography detected in parallel with cardiopulmonary resuscitation (CPR).Among them,7 patients (14%) had pericardial effusion,11 (22%) had hypovolemia,and 39 (78%) were revealed the presence of MVA.In the pseudo PEA subgroup (presence of MVA),43% had ROSC (positive predictive value) and in the true PEA subgroup with cardiac standstill (absence of MVA),there was no recorded ROSC (negative predictive value).Among patients in Group B,no reversible etiology was detected.There was no significant difference in resuscitation results between Groups A and B observed (P=0.52).Conclusion: Bedside echocardiography can identify some reversible causes of PEA.However,there are no significant changes in survival outcome between the echo group and those with traditional CPR.

    Background Cardiopulmonary resuscitation (CPR) is an emergency procedure used to treat victims following cardiopulmonary arrest. Graduate health professionals at the University of Gondar Teaching Hospital manage many trauma and critically ill patients. The chance of survival after cardiopulmonary arrest may be increased with sufficient attitude and skill levels. The study aimed to assess the attitude and skill levels of graduate health professionals in performing CPR. Methods A hospital-based cross-sectional study was conducted from May 1 to 30, 2013, at the University of Gondar Teaching Hospital. The mean attitude and skill scores were compared for sex, original residence, and department of the participants using Student’s t-test and analysis of variance (Scheffe’s test). P-values attitude scores of nurse, interns, health officer, midwifery, anesthesia, and psychiatric nursing graduates were 1.15 (standard deviation [SD] =1.67), 8.21 (SD =1.24), 7.2 (SD =1.49), 6.69 (SD =1.83), 8.19 (SD =1.77), and 7.29 (SD =2.01), respectively, and the mean skill scores were 2.34 (SD =1.95), 3.77 (SD =1.58), 1.18 (SD =1.52), 2.16 (SD =1.93), 3.88 (SD =1.36), and 1.21 (SD =1.77), respectively. Conclusion and recommendations Attitude and skill level of graduate health professionals with regard to CPR were insufficient. Training on CPR for graduate health professionals needs to be given emphasis.

    Full Text Available With the increasing number of old people in all western countries and increasing life expectancy at birth, many seniors spend the last period of their life with various afflictions that may lead to cardiac arrest. Bystander cardiopulmonary resuscitation (CPR increases survival rates. Octogenarians are the fastest growing segment of the population and despite empirical evidence that CPR is of questionable effectiveness in seniors with comorbidities, it is still the only treatment among life-sustaining ones. Cardiopulmonary resuscitation is frequently unsuccessful, but if survival is achieved, a fairly good quality of life can be expected. Various papers analyzed the effect of CPR in hospitalized patients or in cardiac arrest occurring at home or in public places, while less is known about events occurring in the emergency room (ER. We performed a retrospective analysis of cardiac arrest events occurred in ER within 54 months: we analyzed 415,001 records of ER visits (from 01/01/1999 to 30/06/2003 in San Giovanni Addolorata Hospital. Data were analyzed in terms of age and outcome. We identified 475 records with the outcome of death in ER or death on arrival. Out of them, we selected 290 medical records which had sufficient data to be analyzed. Of the 290 patients evaluated, 225 died in ER, 18 were deemed to die on arrival, and 47 survived the cardiac arrest and were admitted to intensive care unit (ICU. The overall mortality was 0.11%, while the incidence of the selected events was 0.072%. The mean age of the analyzed population was 71.3 years. The only possible diagnosis was often cardiac arrest, though most of the times we could specify and group the diagnosis even better. The analysis of the procedures showed that cardiac arrest treated by direct current (DC shock was similarly distributed in different age groups, and no difference was detectable between the two groups. The mean age of the patients who underwent tracheal intubation (TI was

    Summary: The changes of tumor necrosis factor-α (TNF-α) and brain ultrastructure during cardiopulmonary resuscitation and the effects of ulinastation injection were observed, and the mechanism was investigated. Twenty-four adult healthy Sprague-Dawley rats were randomly divided into.control group (8 rats), resuscitation group (8 rats) and ulinastatin (UTI) group (8 rats). Rats in control group underwent tracheotomy without clipping the trachea to induce circulatory and respiratory standstill. Rats in resuscitation and ulinastatin group were subjected to the procedure of establishing the model of cardiopulmonary cerebral resuscitation (CPCR). Rats in ulinastatin group were given with UTI 104 U/kg once after CPCR. In the control group, the plasma was collected immediate,30 min, 2 h, 4 h, and 6 h after tracheotomy. In resuscitation group and UTI group, plasma was collected immediate after tracheotomy, 30 min, 2 h, 4 h and 6 h after successful resuscitation. The plasma levels of TNF-α were determined by radioimmunoassay (RIA). At the end of the experi-ment, 2 rats were randomly selected from each group and were decapitated. The cortex of the brain was taken out immediately to observe the ultrastructure changes. In control group, there were nosignificant differences in the level of TNF-α among different time points (P>0.05). In resuscitation group, the level of TNF-α was increased obviously after resuscitation (P<0.01) and reached its peak 2 h later after resuscitation. An increasing trend of TNF-α showed in UTI group. There were no differences in TNF-α among each sample taken after successful resuscitation and that after tracheotomy. The utrastructure of brains showed the injury in UTI group was ameliorated as compared with that in resuscitation group. In early period of CPCR, TNF-α was expressed rapidly and kept increasing. It indicated that TNF-α might take part in the tissue injury after CPCR. The administration of UTI during CACR could depress TNF

    Every general dental practitioner and oral and maxillofacial surgeon needs a thorough knowledge of the diagnosis and management of medical emergencies. Cardiopulmonary arrest is the most urgent of emergencies and diagnosis must be done as soon as possible. This paper discusses the importance of the International Liaison Committee on Resuscitation which forms the guidelines for cardiopulmonary resuscitation (CPR), highlighting the important changes in the guidelines of CPR from the year 2000 to 2010, the basic sequence of performing CPR and also the role of defibrillation and the use of automated external defibrillators. Finally the five part chain of survival which is of utmost importance to dental health care professionals and oral and maxillofacial surgeons. All dental health care personnel and oral & maxillofacial surgeons should recognize the importance of the changes in the guidelines of CPR, be trained and allowed to use a properly maintained defibrillator, to respond to cardiac arrest victims.

    Thoracic injury in the paediatric population is a relatively common cause of severe injury and has an accompanying high mortality rate. However, no anatomically accurate, complex paediatric chest finite element (FE) component model is available for a 10-year old in the published literature. In this study, a 10-year-old thorax FE model was developed based on internal and external geometries segmented from medical images. The model was then validated against published data measured during cardiopulmonary resuscitation performed on paediatric subjects.

    A study was conducted to determine the level of knowledge about cardiopulmonary resuscitation and automated external defibrillation (AED) in sport instructors working in public sport centers in Asturias. A cross-sectional study was conducted on sports instructors in May 2014, by completing a self-administered questionnaire on cardiopulmonary resuscitation and use of AED, with 25 items and four possible answers, only one valid, divided into five categories (emergency medical system in Asturias, initial assessment, circulation,airway and use of AED). Age, gender, work experience as sports instructor, previous training courses, education and training and employment contract were studied as epidemiological variables. A total 26 questionnaires (52%) were collected in public sports centers, and 84% of total responses were correct. It should be emphasized that among the wrong answers, 42.30% did not know what was the first action in a cardiac arrest, and 36.62% did not know how to perform a complete cardiopulmonary resuscitation if the person affected had a perioral injury, with 46.15% not knowing how to respond to a cardiac arrest due to drowning. It is recommended to include the management of cardiac arrest in their workplace in the training plans and the continuing education of sports instructors, at least every two years, according to national laws and laws from Asturias, including also training on the use and management of AED.

    Updated life-support guidelines were published by the European Resuscitation Council (ERC) in 2010, increasing the required depth and rate of chest compression delivery. This study sought to determine the impact of these guidelines on rescuer fatigue and cardiopulmonary resuscitation (CPR) performance. 62 Health science students performed 5 min of conventional CPR in accordance with the 2010 ERC guidelines. A SkillReporter manikin was used to objectively assess temporal change in determinants of CPR quality. Participants subjectively reported their end-fatigue levels, using a visual analogue scale, and the point at which they believed fatigue was affecting CPR delivery. 49 (79%) participants reported that fatigue affected their CPR performance, at an average of 167 s. End fatigue averaged 49.5/100 (range 0-95). The proportion of chest compressions delivered correctly decreased from 52% in min 1 to 39% in min 5, approaching significance (p=0.071). A significant decline in chest compressions reaching the recommended depth occurred between the first (53%) and fifth (38%) min (p=0.012). Almost half this decline (6%) was between the first and second minutes of CPR. Neither chest compression rate, nor rescue breath volume, were affected by rescuer fatigue. Fatigue affects chest compression delivery within the second minute of CPR under the 2010 ERC guidelines, and is poorly judged by rescuers. Rescuers should, therefore, be encouraged to interchange after 2 min of CPR delivery. Team leaders should be advised to not rely on rescuers to self-report fatigue, and should, instead, monitor for its effects.

    Toll-like receptor 4 (TLR4) activation mediates renal injury in regional ischemia and reperfusion (I/R) models generated by clamping renal pedicles. However, it remains unclear whether TLR4 is causal in the kidney injury following global I/R induced by cardiac arrest (CA) and cardiopulmonary resuscitation (CPR). The present study used wild-type (C3H/HeN) and TLR4-mutant (C3H/HeJ) mice to produce the CA/CPR model. CA was induced by injection of cold KCl and left untreated for different time periods. After resuscitation (72 h), the level of blood urea nitrogen (BUN) and serum creatinine (Scr), as well as histological changes in renal tissue were assessed to evaluate the severity of acute kidney injury (AKI). The expression of TLR4, intercellular adhesion molecule-1 (ICAM-1), myeloperoxidase (MPO) and growth-regulated oncogene-β (GRO-β) in kidney tissues was detected. The results demonstrated that the levels of Scr and BUN increased significantly in C3H/HeN and C3H/HeJ mice after CPR. CPR also resulted in increased expression of TLR4, ICAM-1, GRO-β and MPO in a CA-duration dependent manner. However, there was decreased expression of ICAM-1, GRO-β and MPO in C3H/HeJ mice compared with that in C3H/HeN mice. C3H/HeJ mice were resistant to AKI as demonstrated by the minor changes in renal histology and function following CPR. In conclusion, mice suffered from AKI after successful CPR and severe AKI occurred in mice with prolonged CA duration. TLR4 and its downstream signaling events that promote neutrophil infiltration via ICAM-1 and GRO-β may be important in mediating inflammatory responses to renal injury after CPR. PMID:27510583

    Full Text Available Abstract Background Suboptimal bag ventilation in cardiopulmonary resuscitation (CPR has demonstrated detrimental physiological outcomes for cardiac arrest patients. In light of recent guideline changes for resuscitation, there is a need to identify the efficacy of bag ventilation by prehospital care providers. The objective of this study was to evaluate bag ventilation in relation to operator ability to achieve guideline consistent ventilation rate, tidal volume and minute volume when using two different capacity self-inflating bags in an undergraduate paramedic cohort. Methods An experimental study using a mechanical lung model and a simulated adult cardiac arrest to assess the ventilation ability of third year Monash University undergraduate paramedic students. Participants were instructed to ventilate using 1600 ml and 1000 ml bags for a length of two minutes at the correct rate and tidal volume for a patient undergoing CPR with an advanced airway. Ventilation rate and tidal volume were recorded using an analogue scale with mean values calculated. Ethics approval was granted. Results Suboptimal ventilation with the use of conventional 1600 ml bag was common, with 77% and 97% of participants unable to achieve guideline consistent ventilation rates and tidal volumes respectively. Reduced levels of suboptimal ventilation arouse from the use of the smaller bag with a 27% reduction in suboptimal tidal volumes (p = 0.015 and 23% reduction in suboptimal minute volumes (p = 0.045. Conclusion Smaller self-inflating bags reduce the incidence of suboptimal tidal volumes and minute volumes and produce greater guideline consistent results for cardiac arrest patients.

    Background Mechanical ventilation via automated in-hospital ventilators is quite common during cardiopulmonary resuscitation. It is not known whether different inspiratory triggering sensitivity settings of ordinary ventilators have different effects on actual ventilation, gas exchange and hemodynamics during resuscitation. Methods 18 pigs enrolled in this study were anaesthetized and intubated. Continuous chest compressions and mechanical ventilation (volume-controlled mode, 100% O2, respiratory rate 10/min, and tidal volumes 10ml/kg) were performed after 3 minutes of ventricular fibrillation. Group trig-4, trig-10 and trig-20 (six pigs each) were characterized by triggering sensitivities of 4, 10 and 20 (cmH2O for pressure-triggering and L/min for flow-triggering), respectively. Additionally, each pig in each group was mechanically ventilated using three types of inspiratory triggering (pressure-triggering, flow-triggering and turned-off triggering) of 5 minutes duration each, and each animal matched with one of six random assortments of the three different triggering settings. Blood gas samples, respiratory and hemodynamic parameters for each period were all collected and analyzed. Results In each group, significantly lower actual respiratory rate, minute ventilation volume, mean airway pressure, arterial pH, PaO2, and higher end-tidal carbon dioxide, aortic blood pressure, coronary perfusion pressure, PaCO2 and venous oxygen saturation were observed in the ventilation periods with a turned-off triggering setting compared to those with pressure- or flow- triggering (all P<0.05), except when compared with pressure-triggering of 20 cmH2O (respiratory rate 10.5[10/11.3]/min vs 12.5[10.8/13.3]/min, P = 0.07; coronary perfusion pressure 30.3[24.5/31.6] mmHg vs 27.4[23.7/29] mmHg, P = 0.173; venous oxygen saturation 46.5[32/56.8]% vs 41.5[33.5/48.5]%, P = 0.575). Conclusions Ventilation with pressure- or flow-triggering tends to induce hyperventilation and

    Background Neuroprotective strategies following cardiopulmonary resuscitation (CPR) are an important focus in emergency and critical care medicine. Matrix metalloproteinases (MMPs), especially MMP9 attracted much attention because of its function in focal brain ischemia/reperfusion injury. In the focal cerebral ischemia model in rats, SB-3CT can suppress the expression of MMP9, relieving brain edema, and there was no studies on global cerebral ischemia-reperfusion injury after CPR.Methods One hundred and twenty rats were randomly assigned to sham-operated (n=40), resuscitation treatment (n= 40), and resuscitation control (n= 40) groups. Sham-operated group rats were anesthetized only and intubated tracheally, while the resuscitation treatment and resuscitation control groups also received cardiac arrest by asphyxiation. In the resuscitation treatment group, SB-3CT was injected intraperitoneally after restoring spontaneous circulation (ROSC), defined as restoration of supraventricular rhythm and mean arterial pressure (MAP) ≥ 60 mm Hg for more than 5 minutes. The resuscitation control group also implemented ROSC without injection of SB-3CT. The rats were executed and samples were taken immediately after death, then at 3, 9, 24, and 48 hours (n=8). Brain tissue expression of MMP9 protein, MMP9 mRNA, water content, Evans blue content, TNF-a, IL-1, and IL-6 was measured, and the brain tissue ultramicrostructure studied with electron microscopy.Results In the resuscitation control group, brain tissue expression of MMP9 protein and mRNA, water content, Evans blue content, TNF-a, IL-1, and IL-6 were significantly elevated at 3 hours, and peaked at 24 hours after resuscitation, when compared with the sham-operated group (P <0.05). Tissue ultramicrostructure also changed in the resuscitation control group. By contrast, although all these indexes were increased in the resuscitation treatment group compared with the sham-operated group (P<0.05), they were lower than in the

    It has been reported as an ethical problem within prehospital emergency care that ambulance professionals administer physiologically futile cardiopulmonary resuscitation (CPR) to patients having suffered cardiac arrest to benefit significant others. At the same time it is argued that, under certain circumstances, this is an acceptable moral practice by signalling that everything possible has been done, and enabling the grief of significant others to be properly addressed. Even more general moral reasons have been used to morally legitimize the use of futile CPR: That significant others are a type of patient with medical or care needs that should be addressed, that the interest of significant others should be weighed into what to do and given an equal standing together with patient interests, and that significant others could be benefited by care professionals unless it goes against the explicit wants of the patient. In this article we explore these arguments and argue that the support for providing physiologically futile CPR in the prehospital context fails. Instead, the strategy of ambulance professionals in the case of a sudden death should be to focus on the relevant care needs of the significant others and provide support, arrange for a peaceful environment and administer acute grief counselling at the scene, which might call for a developed competency within this field.

    Full Text Available Good quality cardiopulmonary resuscitation (CPR is the mainstay of treatment for managing patients with out-of-hospital cardiac arrest (OHCA. Assessment of the quality of the CPR delivered is now possible through the electrocardiography (ECG signal that can be collected by an automated external defibrillator (AED. This study evaluates a nonlinear approximation of the CPR given to the asystole patients. The raw ECG signal is filtered using ensemble empirical mode decomposition (EEMD, and the CPR-related intrinsic mode functions (IMF are chosen to be evaluated. In addition, sample entropy (SE, complexity index (CI, and detrended fluctuation algorithm (DFA are collated and statistical analysis is performed using ANOVA. The primary outcome measure assessed is the patient survival rate after two hours. CPR pattern of 951 asystole patients was analyzed for quality of CPR delivered. There was no significant difference observed in the CPR-related IMFs peak-to-peak interval analysis for patients who are younger or older than 60 years of age, similarly to the amplitude difference evaluation for SE and DFA. However, there is a difference noted for the CI (p<0.05. The results show that patients group younger than 60 years have higher survival rate with high complexity of the CPR-IMFs amplitude differences.

    Full Text Available Objective: Cardiopulmonary resuscitation (CPR has been known in its present form since 1960. Different studies have reported variable outcomes among different countries. Therefore, the purpose of this study was to assess the rate of CPR success and the survival rate in managing cardiac arrest among patients in an educational medical center. Methods: This cross-sectional study was performed at Imam Hosein hospital, Tehran, Iran. All patients, admitted to the emergency department with cardiac arrest between March 2007 and January 2008 were included. We used a formerly designed registration form and hospital documentation to retrieve the data of included patients. The main outcomes were the rate of CPR success and the survival rate of these patients. Results: Totally 855 patients were included, from which 510 (59.64% were males. The mean age of included patients was 63 ± 17.6. The CPR process was successful among 364 (42.58% patients. A total number of 101 (11.82% patients were discharged from the hospital. Different factors as the cause of cardiac arrest and past medical problems affected the probability of CPR success and the survival of patients with cardiac arrest. Conclusion: Survival rate at hospital discharge was less than one-third of patients and nearly half of the patients received successful CPR. More intensive care unit (ICU facilities and educational interventions for the emergency staff and the community can enhance the survival of cardiac arrest patients in our health system

    2014-01-01

    Full Text Available Postcardiac arrest brain injury significantly contributes to mortality and morbidity in patients suffering from cardiac arrest (CA. Evidence that shows that mitochondrial dysfunction appears to be a key factor in tissue damage after ischemia/reperfusion is accumulating. However, limited data are available regarding the cerebral mitochondrial dysfunction during CA and cardiopulmonary resuscitation (CPR and its relationship to the alterations of high-energy phosphate. Here, we sought to identify alterations of mitochondrial morphology and oxidative phosphorylation function as well as high-energy phosphates during CA and CPR in a rat model of ventricular fibrillation (VF. We found that impairment of mitochondrial respiration and partial depletion of adenosine triphosphate (ATP and phosphocreatine (PCr developed in the cerebral cortex and hippocampus following a prolonged cardiac arrest. Optimal CPR might ameliorate the deranged phosphorus metabolism and preserve mitochondrial function. No obvious ultrastructural abnormalities of mitochondria have been found during CA. We conclude that CA causes cerebral mitochondrial dysfunction along with decay of high-energy phosphates, which would be mitigated with CPR. This study may broaden our understanding of the pathogenic processes underlying global cerebral ischemic injury and provide a potential therapeutic strategy that aimed at preserving cerebral mitochondrial function during CA.

    Background The purpose of this study was to determine the effect of mild hypothermia therapy on gastric mucosa after cardiopulmonary resuscitation (CPR) and the underlying mechanism. Material/Methods Ventricular fibrillation was induced in pigs. After CPR, the surviving pigs were divided into mild hypothermia-treated and control groups. The changes in vital signs and hemodynamic parameters were monitored before cardiac arrest and at intervals of 0.5, 1, 2, 4, 6, 12, and 24 h after restoration of spontaneous circulation. Serum IL-6 was determined at the same time, and gastroscopy was performed. The pathologic changes were noted, and the expression of IL-6 was determined by hematoxylin and eosin (HE) staining and immunohistochemistry under light. Results The heart rate, mean arterial blood pressure, and cardiac output in both groups did not differ significantly. The gastric mucosa ulcer index evaluated by gastroscopy 2 h and 24 h after restoration of spontaneous circulation (ROSC) in the mild hypothermic group was lower than that the control group (Pgastric mucosa in the mild hypothermic group 6–24 h after ROSC was lower than that in the control group (Pgastric mucosa IL-6 expression 0.5–4 h and 6, 12, and 24 h after ROSC was lower in the mild hypothermic group than in the control group (Pgastric mucosa after ROSC via inhibiting IL-6 production and relieving the inflammatory reaction.

    Performance of efficient single-person cardiopulmonary resuscitation (CPR) is vital to maintain cardiac and cerebral perfusion during the 2-4 min it takes for deployment of advanced life support during a space mission. The aim of the present study was to investigate potential differences in upper body muscle activity during CPR performance at terrestrial gravity (+1Gz) and in simulated microgravity (μG). Muscle activity of the triceps brachii, erector spinae, rectus abdominis and pectoralis major was measured via superficial electromyography in 20 healthy male volunteers. Four sets of 30 external chest compressions (ECCs) were performed on a mannequin. Microgravity was simulated using a body suspension device and harness; the Evetts-Russomano (ER) method was adopted for CPR performance in simulated microgravity. Heart rate and perceived exertion via Borg scores were also measured. While a significantly lower depth of ECCs was observed in simulated microgravity, compared with +1Gz, it was still within the target range of 40-50 mm. There was a 7.7% decrease of the mean (±SEM) ECC depth from 48 ± 0.3 mm at +1Gz, to 44.3 ± 0.5 mm during microgravity simulation (p muscular and cardiovascular deconditioning that occurs during space travel.

    We investigated the use of blood color brightness and blood gas variables for discriminating arterial from venous puncture during cardiopulmonary resuscitation (CPR). The study's aims were to determine if discrimination using Po2 is superior to using blood color brightness, and if blood color brightness, Po2, and acid-base variables derived from blood gas analysis accurately discriminate arterial from venous blood during CPR. Fifteen pigs underwent ventricular fibrillation followed by CPR. During CPR, paired femoral arterial and venous blood samples were obtained, and 2 blinded observers were asked to identify the blood's origin. Blood color brightness was measured using a blood brightness scale (BBS). The discriminatory performances of the BBS and blood gas variables were evaluated by calculating the area under receiver operating characteristic curves (AUC). The observers accurately discriminated arterial from venous blood with a sensitivity of 97.0% (84.7%-99.5%) and specificity of 84.9% (69.1%-93.4%). The BBS (AUC = 0.983) and Po2 (AUC = 0.981) methods both showed comparable and excellent discriminatory performances. pH, Pco2, and HCO3(-) all discriminated arterial from venous blood (AUC = 0.831, 0.971, and 0.652, respectively). The AUC for Pco2 was comparable to that for Po2 but significantly larger than that for pH (P = .002) or HCO3(-) (P arterial from venous blood during CPR with statistical significance.

    We evaluated the association of body temperature patterns with neurological outcomes after extracorporeal cardiopulmonary resuscitation (ECPR). Between December 2013 and December 2015, we enrolled 48 patients with cardiac arrest who survived for at least 24 hours after ECPR. Based on their body temperature patterns and the intention to control fever, we divided the patients into those in whom fever was actively controlled (N = 25), those with normothermia (N = 17), and those with unintended hypothermia (N = 6). The primary outcome was the Cerebral Performance Categories (CPC) scale at discharge. Of the 48 ECPR patients, 23 patients (47.9%) had good neurological outcomes (CPC 1 and 2) and 27 patients (56.3%) survived to discharge. The normothermia group showed a pattern of higher temperatures compared with the other groups during 48 hours after ECPR. Not only poor neurological outcomes but also intensive care unit (ICU) mortality occurred more often in the unintended hypothermia group than in the other two groups, regardless of the fever control strategy (p = 0.023 and p = 0.002, respectively). There were no differences in neurological outcomes and ICU mortality between the actively controlled fever group and the normothermia group (p = 0.845 and p = 0.616, respectively). Unintentionally sustained hypothermia may be associated with poor neurological outcomes after ECPR. These findings suggest that patients who are unable to generate a fever following ECPR may incur severe hypoxic brain injury. PMID:28114337

    Full Text Available Road traffic accident victims, as well as persons experiencing cardiac and other medical emergencies, might lose their lives due to the non-availability of trained personnel to provide effective cardio-pulmonary resuscitation (CPR with functional equipment and adequate resources.The objectives of the study were to identify unit managers’ perceptions about challenges encountered when performing CPR interventions in the two referral public hospitals in Botswana. These results could be used to recommend more effective CPR strategies for Botswana’s hospitals. Interviews, comprising two quantitative sections with closed ended questions and one qualitative section with semi-structured questions, were conducted with 22 unit managers. The quantitative data indicated that all unit managers had at least eight years’ nursing experience, and could identify CPR shortcomings in their hospitals. Only one interviewee had never performed CPR. The qualitative data analysis revealed that the hospital units sometimes had too few staff members and did not have fully equipped emergency trolleys and/or equipment. No CPR teams and no CPR policies and guidelines existed. Nurses and doctors reportedly lacked CPR knowledge and skills. No debriefing services were provided after CPR encounters. The participating hospitals should address the following challenges that might affect CPR outcomes: shortages of staff, overpopulation of hospital units, shortcomings of the emergency trolleys and CPR equipment, absence of CPR policies and guidelines, absence of CPR teams, limited CPR competencies of doctors and nurses and the lack of debriefing sessions after CPR attempts.

    The success rate of cardiopulmonary resuscitation (CPR) may differ from institution to institution, even within different sites in the same institution. A variety of factors may influence the outcome. In this study, we assessed the adequacy of CPR attempts guided by the current standards and aimed to define the factors influencing the outcome following in-hospital cardiac arrest. One hundred and thirty-four patients who required CPR were studied prospectively. Different variables for the CPR performance were recorded using forms designed for this study in the light of the guidelines. In these CPR forms various data including the demographics, history, monitoring, number, composition and experience of the anaesthesiologists, the site of CPR, time of day, the delay before onset of CPR, tracheal intubation, duration of arrest, initial rhythm in ECG monitored patients, management of CPR, drug administration and reversible causes of cardiac arrest were recorded. Our rates of immediate survival, survival at 24 h and survival to discharge 49.3%, 28.5% and 13.4%, respectively. The extent of monitoring prior to arrest, the attendance of one or more experienced anesthesiologists in the CPR team, CPR during office hours, CPR in ICU or operating room, early initiation of CPR and tracheal intubation prior to arrest were found as the factors increasing discharge survival. We conclude that early initiation of CPR with an experienced team in a well-equipped hospital sites increases the discharge survival rate following cardiac arrest.

    Outcomes of cardiopulmonary resuscitation (CPR) in hospitalized patients with ESRD requiring maintenance dialysis are unknown. Outcomes of in-hospital CPR in these patients were compared with outcomes in the general population using data from the Nationwide Inpatient Sample (NIS; 2005-2011). The study population included all adults (≥ 18 years old) from the general population and those with a history of ESRD. Baseline characteristics, in-hospital complications, and discharge outcomes were compared between the two groups. The effects of in-hospital CPR on mortality, length of stay, hospitalization charges, and discharge destination were analyzed. Yearly national trends in survival, discharge to home, and length of stay were also examined using the Cochran-Armitage trend test. During the study period, 56,069 patients with ESRD underwent in-hospital CPR compared with 323,620 patients from the general population. Unadjusted in-hospital mortality rates were higher in patients with ESRD (73.9% versus 71.8%, PCPR improved in the year 2011 compared with 2005 (31% versus 21%, PCPR are improving in patients with ESRD but remain worse than outcomes in the general population. Patients with ESRD who survive are more likely to be discharged to nursing homes.

    Full Text Available Objective. There are many smartphone-based applications (apps for cardiopulmonary resuscitation (CPR training. We investigated the conformity and the learnability/usability of these apps for CPR training and real-life supports. Methods. We conducted a mixed-method, sequential explanatory study to assess CPR training apps downloaded on two apps stores in South Korea. Apps were collected with inclusion criteria as follows, Korean-language instruction, training features, and emergency supports for real-life incidents, and analyzed with two tests; 15 medical experts evaluated the apps’ contents according to current Basic Life Support guidelines in conformity test, and 15 nonmedical individuals examined the apps using System Usability Scale (SUS in the learnability/usability test. Results. Out of 79 selected apps, five apps were included and analyzed. For conformity (ICC, 0.95, p<0.001, means of all apps were greater than 12 of 20 points, indicating that they were well designed according to current guidelines. Three of the five apps yielded acceptable level (greater than 68 of 100 points for learnability/usability. Conclusion. All the included apps followed current BLS guidelines and a majority offered acceptable learnability/usability for layperson. Current and developmental smartphone-based CPR training apps should include accurate CPR information and be easy to use for laypersons that are potential rescuers in real-life incidents.

    The decision whether to receive cardiopulmonary resuscitation (CPR) is a decision in which the personal values of the patient must be considered along with information about the risks and benefits of the treatment. A decision aid can be used to provide patient decision support to a patient who is seriously ill and needs to consider CPR options. The goal of this project was to identify the barriers and facilitators to using a CPR decision aid, through evaluating nursing perceptions on providing patient decision support. Using a needs assessment, it was determined that implementing a patient decision aid for CPR status in the Acute Monitor Area (AMA) of The Ottawa Hospital would be an excellent quality improvement project. The nurses who chose to participate were given an education session regarding patient decision support. Questionnaires were distributed to evaluate their views of patient decision support and decision aids before and after the education session and implementation of the CPR decision aid. Questionnaire results did not indicate a significant change between before or after education session and decision aid implementation. Qualitative reports did indicate that nurses generally have positive attitudes toward patient decision support and decision aids. The nurses identified specific barriers and facilitators in their commentaries. This clinically relevant data supports the idea that patient decision support should be integrated into daily nursing practice.

    Foundation Year One (FY1) doctors are often the first medical staff responders at in-hospital cardiac arrests. The study objectives were to assess the cardiopulmonary resuscitation (CPR) skills of FY1 doctors at a Belfast teaching hospital and to highlight factors that influence their performance. A group of FY1 doctors working in a Belfast teaching hospital were asked to participate in this study. These junior doctors were regularly on-call for acute medical emergencies including cardiac arrest. Participants were instructed to perform two, 3 minute sessions of CPR on a skills reporter manikin. Each session was separated by a 5 minute rest period, one session using a compression-to-ventilation ratio of 15:2 and the other using a ratio of 30:2. Performance was gauged both objectively, by measuring the depth of chest compressions, and subjectively by a panel of 5 Advanced Life Support (ALS) instructors who reviewed the tracings of each CPR session. Overall, 85% of medical FY1's working in the hospital participated in the study. Objective results determined that males performed significantly better than their female counterparts using both the 15:2 and 30:2 ratios. The male FY1 doctors performed equally well using both 15:2 and 30:2 ratios, in comparison to female doctors who were noted to be better using the 15:2 ratio. Individuals with a Body mass index (BMI) greater than the mean for the group, performed significantly better than those with a lower BMI when using the 30:2 ratio. BMI was an important factor and correlated with chest compression depth. Females with a low BMI performed less well when using a ratio of 30:2. Overall, expert opinion significantly favoured the 15:2 ratio for the FY1 doctor group. CPR performance can be influenced by factors such as gender and BMI, as such the individual rescuer should take these into account when determining which compression to ventilation ration to perform in order to maximise patient outcome. This study showed that

  11. Feedback on the Rate and Depth of Chest Compressions during Cardiopulmonary Resuscitation Using Only Accelerometers.

    Full Text Available Quality of cardiopulmonary resuscitation (CPR is key to increase survival from cardiac arrest. Providing chest compressions with adequate rate and depth is difficult even for well-trained rescuers. The use of real-time feedback devices is intended to contribute to enhance chest compression quality. These devices are typically based on the double integration of the acceleration to obtain the chest displacement during compressions. The integration process is inherently unstable and leads to important errors unless boundary conditions are applied for each compression cycle. Commercial solutions use additional reference signals to establish these conditions, requiring additional sensors. Our aim was to study the accuracy of three methods based solely on the acceleration signal to provide feedback on the compression rate and depth.We simulated a CPR scenario with several volunteers grouped in couples providing chest compressions on a resuscitation manikin. Different target rates (80, 100, 120, and 140 compressions per minute and a target depth of at least 50 mm were indicated. The manikin was equipped with a displacement sensor. The accelerometer was placed between the rescuer's hands and the manikin's chest. We designed three alternatives to direct integration based on different principles (linear filtering, analysis of velocity, and spectral analysis of acceleration. We evaluated their accuracy by comparing the estimated depth and rate with the values obtained from the reference displacement sensor.The median (IQR percent error was 5.9% (2.8-10.3, 6.3% (2.9-11.3, and 2.5% (1.2-4.4 for depth and 1.7% (0.0-2.3, 0.0% (0.0-2.0, and 0.9% (0.4-1.6 for rate, respectively. Depth accuracy depended on the target rate (p < 0.001 and on the rescuer couple (p < 0.001 within each method.Accurate feedback on chest compression depth and rate during CPR is possible using exclusively the chest acceleration signal. The algorithm based on spectral analysis showed the

    Cardiopulmonary resuscitation (CPR) improves outcomes after cardiac arrest. Much of the lay public is untrained in CPR skills. We evaluated the effectiveness of a compression-only CPR video self-instruction (VSI) with a personal manikin in the lay public. Adults without prior CPR training in the past year or responsibility to provide medical care were randomized into one of three groups: 1) Untrained before testing, 2) 10-minute VSI in compressions-only CPR (CPR Anytime, American Heart Association, Dallas, TX), or 3) 22-minute VSI in compressions and ventilations (CPR Anytime). CPR proficiency was assessed using a sensored manikin. The primary outcome was composite skill competence of 90% during five minutes of skill demonstration. Evaluated were alternative cut-points for skill competence and individual components of CPR. 488 subjects (143 in untrained group, 202 in compressions-only group and 143 in compressions and ventilation group) were required to detect 21% competency with compressions-only versus 7% with untrained and 34% with compressions and ventilations. Analyzable data were available for the untrained group (n = 135), compressions-only group (n = 185) and the compressions and ventilation group (n = 119). Four (3%) achieved competency in the untrained group (p-value = 0.57 versus compressions-only), nine (4.9%) in the compressions-only group, and 12 (10.1%) in the compressions and ventilations group (p-value 0.13 vs. compressions-only). The compressions-only group had a greater proportion of correct compressions (p-value = 0.028) and compressions with correct hand placement (p-value = 0.0004) compared to the untrained group. VSI in compressions-only CPR did not achieve greater overall competency but did achieve some CPR skills better than without training.

    Most pediatric in-hospital cardiac arrests (IHCAs) occur in ICUs where invasive hemodynamic monitoring is frequently available. Titrating cardiopulmonary resuscitation (CPR) to the hemodynamic response of the individual improves survival in preclinical models of adult cardiac arrest. The objective of this study was to determine if titrating CPR to systolic blood pressure (SBP) and coronary perfusion pressure (CoPP) in a pediatric porcine model of asphyxia-associated ventricular fibrillation (VF) IHCA would improve survival as compared to traditional CPR. After 7min of asphyxia followed by VF, 4-week-old piglets received either hemodynamic-directed CPR (HD-CPR; compression depth titrated to SBP of 90mmHg and vasopressor administration to maintain CoPP ≥20mmHg); or Standard Care (compression depth 1/3 of the anterior-posterior chest diameter and epinephrine every 4min). All animals received CPR for 10min prior to the first defibrillation attempt. CPR was continued for a maximum of 20min. Protocolized intensive care was provided to all surviving animals for 4h. The primary outcome was 4-h survival. Survival rate was greater with HD-CPR (12/12) than Standard Care (6/10; p=0.03). CoPP during HD-CPR was higher compared to Standard Care (point estimate +8.1mmHg, CI95: 0.5-15.8mmHg; p=0.04). Chest compression depth was lower with HD-CPR than Standard Care (point estimate -14.0mm, CI95: -9.6 to -18.4mm; pCPR vs. Standard Care (median 5 vs. 2; pCPR improves short-term survival compared to standard depth-targeted CPR in a porcine model of pediatric asphyxia-associated VF IHCA.

    Initiation of early bystander cardiopulmonary resuscitation (CPR) depends on bystanders' or medical dispatchers' recognition of out-of-hospital cardiac arrest (OHCA). The primary aim of our study was to investigate if OHCA recognition during the emergency call was associated with bystander CPR, return of spontaneous circulation (ROSC), and 30-day survival. Our secondary aim was to identify patient-, setting-, and dispatcher-related predictors of OHCA recognition. We performed an observational study of all OHCA patients' emergency calls in the Capital Region of Denmark from 01/01/2013-31/12/2013. OHCAs were collected from the Danish Cardiac Arrest Registry and the Mobile Critical Care Unit database. Emergency call recordings were identified and evaluated. Multivariable logistic regression analyses were applied to all OHCAs and witnessed OHCAs only to analyse the association between OHCA recognition and bystander CPR, ROSC, and 30-day survival. Univariable logistic regression analyses were applied to identify predictors of OHCA recognition. We included 779 emergency calls in the analyses. During the emergency calls, 70.1% (n=534) of OHCAs were recognised; OHCA recognition was positively associated with bystander CPR (odds ratio [OR]=7.84, 95% confidence interval [CI]: 5.10-12.05) in all OHCAs; and ROSC (OR=1.86, 95% CI: 1.13-3.06) and 30-day survival (OR=2.80, 95% CI: 1.58-4.96) in witnessed OHCA. Predictors of OHCA recognition were addressing breathing (OR=1.76, 95% CI: 1.17-2.66) and callers located by the patient's side (OR=2.16, 95% CI: 1.46-3.19). Recognition of OHCA during emergency calls was positively associated with the provision of bystander CPR, ROSC, and 30-day survival in witnessed OHCA. Copyright © 2017 The Authors.

    Full Text Available Context: Cardiopulmonary resuscitation (CPR and emergency cardiovascular care guidelines are periodically renewed and published by the American Heart Association. Formal training programs are conducted based on these guidelines. Despite widespread training CPR is often poorly performed. Hospital educators spend a significant amount of time and money in training health professionals and maintaining basic life support (BLS and advanced cardiac life support (ACLS skills among them. However, very little data are available in the literature highlighting the long-term impact of these training. Aims: To evaluate the impact of formal certified CPR training program on the knowledge and skill of CPR among nurses, to identify self-reported outcomes of attempted CPR and training needs of nurses. Setting and Design : Tertiary care hospital, Prospective, repeated-measures design. Subjects and Methods: A series of certified BLS and ACLS training programs were conducted during 2010 and 2011. Written and practical performance tests were done. Final testing was undertaken 3-4 years after training. The sample included all available, willing CPR certified nurses and experience matched CPR noncertified nurses. Statistical Analysis Used: SPSS for Windows version 21.0. Results: The majority of the 206 nurses (93 CPR certified and 113 noncertified were females. There was a statistically significant increase in mean knowledge level and overall performance before and after the formal certified CPR training program (P = 0.000. However, the mean knowledge scores were equivalent among the CPR certified and noncertified nurses, although the certified nurses scored a higher mean score (P = 0.140. Conclusions: Formal certified CPR training program increases CPR knowledge and skill. However, significant long-term effects could not be found. There is a need for regular and periodic recertification.

    The passive leg-raising (PLR) maneuver has been used for patients with circulatory failure to improve hemodynamic responsiveness by increasing cardiac output, which should also be beneficial and may exert synergetic effects during cardiopulmonary resuscitation (CPR). However, the impact of the PLR maneuver on CPR remains unclear due to difficulties in monitoring cardiac output in real-time during CPR and a lack of clinical evidence. We developed a computational model that couples hemodynamic behavior during standard CPR and the PLR maneuver, and simulated the model by applying different angles of leg raising from 0° to 90° and compression rates from 80/min to 160/min. The simulation results showed that the PLR maneuver during CPR significantly improves cardiac output (CO), systemic perfusion pressure (SPP) and coronary perfusion pressure (CPP) by ∼40-65% particularly under the recommended range of compression rates between 100/min and 120/min with 45° of leg raise, compared to standard CPR. However, such effects start to wane with further leg lifts, indicating the existence of an optimal angle of leg raise for each person to achieve the best hemodynamic responses. We developed a CPR-PLR model and demonstrated the effects of PLR on hemodynamics by investigating changes in CO, SPP, and CPP under different compression rates and angles of leg raising. Our computational model will facilitate study of PLR effects during CPR and the development of an advanced model combined with circulatory disorders, which will be a valuable asset for further studies.

    Cardiopulmonary resuscitation (CPR) training in schools is recommended to increase bystander CPR and thereby survival of out-of-hospital cardiac arrest, but despite mandating legislation, low rates of implementation have been observed in several countries, including Denmark. The purpose of the study was to explore barriers to implementation of CPR training in Danish secondary schools. A qualitative study based on individual interviews and focus groups with school leadership and teachers. Thematic analysis was used to identify regular patterns of meaning both within and across the interviews. 8 secondary schools in Denmark. Schools were selected using strategic sampling to reach maximum variation, including schools with/without recent experience in CPR training of students, public/private schools and schools near to and far from hospitals. The study population comprised 25 participants, 9 school leadership members and 16 teachers. School leadership and teachers considered it important for implementation and sustainability of CPR training that teachers conduct CPR training of students. However, they preferred external instructors to train students, unless teachers acquired the CPR skills which they considered were needed. They considered CPR training to differ substantially from other teaching subjects because it is a matter of life and death, and they therefore believed extraordinary skills were required for conducting the training. This was mainly rooted in their insecurity about their own CPR skills. CPR training kits seemed to lower expectations of skill requirements to conduct CPR training, but only among those who were familiar with such kits. To facilitate implementation of CPR training in schools, it is necessary to have clear guidelines regarding the required proficiency level to train students in CPR, to provide teachers with these skills, and to underscore that extensive skills are not required to provide CPR. Further, it is important to familiarise

    Full Text Available Percutaneous cardiopulmonary support (PCPS has been applied for cardiopulmonary arrest (CPA. We have developed a novel method of cardiopulmonary resuscitation using PCPS combined with liposome-encapsulated hemoglobin (TRM645 to improve oxygen delivery to vital organs. Ventricular fibrillation was electrically induced to an adult goat for 10 min. Next, PCPS (30 ml/kg/min, V/Q: 1 was performed for 20 min. Then, external defibrillation was attempted and observed for 120 min. The TRM group (n5 was filled with 300 mL of TRM645 for the PCPS circuit. The control group (n5 was filled with the same volume of saline. The delivery of oxygen (DO2 and oxygen consumption (VO2 decreased markedly by PCPS after CPA, compared to the preoperative values. DO2 was kept at a constant level during PCPS in both groups, but VO2 slowly decreased at 5, 10, and 15 min of PCPS in the control groups, demonstrating that systemic oxygen metabolism decreased with time. In contrast, the decreases in VO2 were small in the TRM group at 5, 10, and 15 min of PCPS, demonstrating that TRM645 continuously maintained systemic oxygen consumption even at a low flow rate. AST and LDH in the TRM group were lower than the control. There were significant differences at 120 min after the restoration of spontaneous circulation (p<0.05.

    In a recently published German multicenter study, 25% of the patients with witnessed cardiac arrest outside the hospital were resuscitated successfully and discharged from the hospital. Approximately 100,000 people suffer a fatal cardiac arrest in Germany annually, which is approximately tenfold the number of deaths from motor vehicle accidents. Cardiopulmonary resuscitation (CPR) performed by bystanders is an important part of the chain of survival to minimize the time interval without artificial circulation and ventilation in a cardiac arrest victim. This is especially important in areas with long response times of the emergency medical service (EMS). Early examples of ventilation have been described throughout history. References to mouth-to-mouth ventilation (MTMV) are found in the Bible, in a description of the resuscitation of a coal miner in 1744, and in an experiment in 1796 demonstrating that exhaled gas was safe for breathing. In 1954, Elam and colleagues described artificial respiration with the exhaled gas of a rescuer using a mouth-to-mask ventilation method. The modern CPR era started with the combination of MTMV and chest compressions 35 years ago. However, the value of MTMV is currently under discussion because of a widespread fear of transmission of infectious diseases. Healthcare professionals have stated in several studies that they may withhold MTMV when confronted with a cardiac arrest in a stranger. Although an infection with Mycobacterium tuberculosis is more likely than one with HIV via MTMV, the fear of the public is understandable. An expert committee of the American Heart Association stated that MTMV may be omitted in the initial phase of cardiac arrest, and considered recommending chest compressions only if the EMS will arrive rapidly. In paralyzed volunteers, however, ventilation induced by chest compressions was not able to provide sufficient gas exchange, especially when the airway was not protected.

    Possible correlations between the circulatory and neurological responses to cardiopulmonary resuscitation (CPR) and the influence of pre-arrest factors (demographic data, medical history and aetiology of circulatory arrest) and arrest factors (location of arrest, ECG configurations, and duration of resuscitation) on the course of circulatory and neurological recovery were investigated in 111 victims of circulatory arrest. At the start of resuscitation 57 patients (Group I) had some brain function and 54 (Group II) had no brain function. Sixty nine patients (62%) had circulation restored but 54 (78%) were left with heart failure. Forty one patients (39%) survived the first day, 26 (63%) with heart failure; only 34 (31%) were alive after 48 h, 17 (50%) with heart failure. Half of the patients surviving 24 or 48 h had awakened. Consciousness returned in 32 patients (29%) during the first 48 h, more frequently in Group I than in Group II. Patients in Group I had a higher incidence of in-hospital arrest and had their circulation restored more often than those in Group II. Survival and post-resuscitation heart failure was alike in the groups. The pre-arrest factors explored did not modify the circulatory or neurological outcome whereas initial ventricular fibrillation was significantly related to recovery of consciousness. The revivability of spontaneous circulation and of neurological functions was found thus mainly to be determined by global ischaemia sustained prior to and during CPR.

    A head-to-head trial was conducted to compare laypersons' long-term retention of life-saving psychomotor and cognitive skills learned in the traditional multi-hour training format for basic cardiopulmonary resuscitation and automated external defibrillator use to those learned in an abbreviated (30 min) course. Laypersons were randomized to either: (1) the traditional multi-hour Heartsaver-Automated External Defibrillator (Heartsaver-AED) group; or (2) the 30-min course group (cardiopulmonary resuscitation, choking, and automated external defibrillator use). Immediately after training, and at 6 months, participants were provided identical individual testing scenarios. In addition to audio-video recordings, computerized recordings of compression rate/depth, ventilation rates, and related pauses were obtained and subsequently rated by blinded reviewers. Performance following 30-min training was either equivalent or superior (p<0.007) to the multi-hour Heartsaver-Automated External Defibrillator training in all measurements, both immediately and 6 months after training. Although retention of certain skills deteriorated over the 6 months among a significant number of participants from both groups, 84% of the 30-min training group still was judged, overall, to perform cardiopulmonary resuscitation adequately. Moreover, 93% still were performing chest compressions adequately and 93% continued to apply the automated external defibrillator and deliver shocks correctly. Using innovative learning techniques, 30-min cardiopulmonary resuscitation and automated external defibrillator training is as effective as traditional multi-hour courses, even after 6 months. Thirty-minute courses should decrease labor intensity, demands on resources, and time commitments for cardiopulmonary resuscitation courses, thus facilitating more widespread and frequent retraining.

    2014-09-12

    Sudden cardiac arrest (SCA) is a common health problem associated with high levels of mortality. Cardiac arrest is caused by three groups of dysrhythmias: ventricular fibrillation (VF) or pulseless ventricular tachycardia (VT), pulseless electric activity (PEA) and asystole. The most common dysrhythmia found in out-of-hospital cardiac arrest (OHCA) is VF. During VF or VT, cardiopulmonary resuscitation (CPR) provides perfusion and oxygenation to the tissues, whilst defibrillation restores a viable cardiac rhythm. Early successful defibrillation is known to improve outcomes in VF/VT. However, it has been hypothesized that a period of CPR before defibrillation creates a more conducive physiological environment, increasing the likelihood of successful defibrillation. The order of priority of CPR versus defibrillation therefore remains in contention. As previous studies have remained inconclusive, we conducted a systematic review of available evidence in an attempt to draw conclusions on whether CPR plus delayed defibrillation or immediate defibrillation resulted in better outcomes in OHCA. To examine whether an initial one and one-half to three minutes of CPR administered by paramedics before defibrillation versus immediate defibrillation on arrival influenced survival rates, neurological outcomes or rates of return of spontaneous circulation (ROSC) in OHCA. We searched the following databases: the Cochrane Central Register of Controlled trials (CENTRAL) (2013, Issue 6); MEDLINE (Ovid) (1948 to May 2013); EMBASE (1980 to May 2013); the Institute for Scientific Information (ISI) Web of Science (1980 to May 2013) and the China Academic Journal Network Publishing Database (China National Knowledge Infrastructure (CNKI), 1980 to May 2013). We included studies published in all languages. We also searched the Current Controlled Trials and Clinical Trials databases for ongoing trials. We screened the references lists of studies included in our review against the reference

    Full Text Available Introduction: Out-of-hospital cardiac arrest (OHCA is the most stressful lifetime event for the victims and an important issue for the emergency physicians. The status of the hypothalamic pituitary- adrenal axis (HPA function in successfully resuscitated victims of cardiopulmonary arrest has been recently of an interest for the researchers. Methods: In a prospective cohort study, 50 successfully resuscitated OHCA victims’ serum cortisol levels were measured 5 minutes and 1 hour after return of spontaneous circulation (ROSC. The data were analyzed comparing the one-week neurologic survival. Results: Fifty blood samples were obtained for serum cortisol levels after 5 minutes of ROSC. Fourteen patients (28% pronounced death during one hour after CPR. Blood sample from living 36 patients after one hour post-CPR were obtained for second cortisol assay. Eleven patients (22% were neurologically survived after one week. Seven patients (14% were discharged finally from hospital with good neurologic recovery. The serum cortisol levels in both the neurologically surviving and the non-surviving after 5 minutes of ROSC patients were 63.4 ±13.6 and 43.2±25.5(microg/ml, (mean±S.D., respectively and after 1 hour of ROSC patients’ serum cortisol levels were 64.9±13.1 and 47.3±27.1(microg/ml, (mean±S.D., respectively. The difference was significantly higher in neurologically survived group in both 5 minutes and 1 hour after ROSC (P= 0.015 and 0.013 respectively. Conclusion: serum cortisol levels after 5 minutes and one hour of ROSC in victims of cardiopulmonary arrest are significantly higher in neurologically survived than non-survived patients.

    The American Heart Association (AHA) guidelines for cardiopulmonary resuscitation (CPR) are nowadays recognized as the world's most authoritative resuscitation guidelines. Adherence to these guidelines optimizes the management of critically ill patients and increases their chances of survival after cardiac arrest. Despite their availability, suboptimal quality of CPR is still common. Currently, the median hospital survival rate after pediatric in-hospital cardiac arrest is 36%, whereas it falls below 10% for out-of-hospital cardiac arrest. Among emerging information technologies and devices able to support caregivers during resuscitation and increase adherence to AHA guidelines, augmented reality (AR) glasses have not yet been assessed. In order to assess their potential, we adapted AHA Pediatric Advanced Life Support (PALS) guidelines for AR glasses. The study aimed to determine whether adapting AHA guidelines for AR glasses increased adherence by reducing deviation and time to initiation of critical life-saving maneuvers during pediatric CPR when compared with the use of PALS pocket reference cards. We conducted a randomized controlled trial with two parallel groups of voluntary pediatric residents, comparing AR glasses to PALS pocket reference cards during a simulation-based pediatric cardiac arrest scenario-pulseless ventricular tachycardia (pVT). The primary outcome was the elapsed time in seconds in each allocation group, from onset of pVT to the first defibrillation attempt. Secondary outcomes were time elapsed to (1) initiation of chest compression, (2) subsequent defibrillation attempts, and (3) administration of drugs, as well as the time intervals between defibrillation attempts and drug doses, shock doses, and number of shocks. All these outcomes were assessed for deviation from AHA guidelines. Twenty residents were randomized into 2 groups. Time to first defibrillation attempt (mean: 146 s) and adherence to AHA guidelines in terms of time to other

    The use of extracorporeal life support (ECLS) in cardiopulmonary resuscitation (CPR; ECPR) has been repeatedly published as non-randomized studies, mainly case series and case reports. The aim of this article is to support physicians, perfusionists, nurses and extracorporeal membrane oxygenation (ECMO) specialists who regularly perform ECPR or are willing to start an ECPR program by establishing standards for safe and efficient ECPR procedures. This article represents the experience and recommendations of physicians who provide ECPR routinely. Based on its survival and outcome rates, ECPR can be considered when determining the optimal treatment of patients who require CPR. The successful performance of ECLS cannulation during CPR is a life-saving measure and has been associated with improved outcome (including neurological outcome) after CPR. We summarize the general structure of an ECLS team and describe the cannulation procedure and the approaches for post-resuscitation care. The differences in hospital organizations and their regulations may result in variations of this model. © The Author(s) 2015.

    Cardiopulmonary resuscitation (CPR) is used widely to rescue cardiac arrest patients, yet some physiological aspects of the procedure remain poorly understood. We conducted this study to characterize the dynamic mechanical properties of the thorax during CPR in a swine model. This is an important step toward determining optimal CPR chest compression mechanics with the goals of improving the fidelity of CPR simulation manikins and ideally chest compression delivery in real-life resuscitations. This paper presents a novel nonlinear model of the thorax that captures the complex behavior of the chest during CPR. The proposed model consists of nonlinear elasticity and damping properties along with frequency dependent hysteresis. An optimization technique was used to estimate the model coefficients for force-compression using data collected from experiments conducted on swine. To track clinically relevant, time-dependent changes of the chest's properties, the data was divided into two time periods, from 1 to 10 min (early) and greater than 10 min (late) after starting CPR. The results showed excellent agreement between the actual and the estimated forces, and energy dissipation due to viscous damping in the late stages of CPR was higher when compared to the earlier stages. These findings provide insight into improving chest compression mechanics during CPR, and may provide the basis for developing CPR simulation manikins that more accurately represent the complex real world changes that occur in the chest during CPR.

    Reducing hands-off time during cardiopulmonary resuscitation (CPR) is believed to increase survival after cardiac arrests because of the sustaining of organ perfusion. The aim of our study was to investigate whether charging the defibrillator before rhythm analyses and shock delivery significantly reduced hands-off time compared with the European Resuscitation Council (ERC) 2010 CPR guideline algorithm in full-scale cardiac arrest scenarios. The study was designed as a full-scale cardiac arrest simulation study including administration of drugs. Participants were randomized into using the Stop-Only-While-Shocking (SOWS) algorithm or the ERC2010 algorithm. In SOWS, chest compressions were only interrupted for a post-charging rhythm analysis and immediate shock delivery. A Resusci Anne HLR-D manikin and a LIFEPACK 20 defibrillator were used. The manikin recorded time and chest compressions. Sample size was calculated with an α of 0.05 and 80% power showed that we should test four scenarios with each algorithm. Twenty-nine physicians participated in 11 scenarios. Hands-off time was significantly reduced 17% using the SOWS algorithm compared with ERC2010 [22.1% (SD 2.3) hands-off time vs. 26.6% (SD 4.8); P<0.05]. In full-scale cardiac arrest simulations, a minor change consisting of charging the defibrillator before rhythm check reduces hands-off time by 17% compared with ERC2010 guidelines.

    The two-thumb encircling (TTE) technique often results in suboptimal cardiac compression and does not meet the requirements of current resuscitation guidelines. We compared this technique with the vertical two-thumb (VTT) technique, our novel modification of the TTE technique. This was a prospective randomised crossover simulation study of out-of-hospital infant cardiopulmonary resuscitation (CPR). Participants who had completed a basic life support course performed 10 cycles of cardiac compressions on a manikin for each technique. We enrolled 36 medical doctors who had applied for a hospital internship in this study. The VTT generated significantly higher pressure than the TTE and the pressure difference ranged from 26.8 to 62.9 mmHg for each cycle, with a mean difference of 43.5 mmHg (95% CI, 37.8-49.2). The difference in pressure showed a tendency to increase with increasing cycles of cardiac compressions. The participants' heart and respiratory rate was higher with the VTT, but they said that it was easier to perform cardiac compressions with this technique. The VTT technique generated more pressure than the TTE technique in a simulated model of infant out-of-hospital CPR. It can provide an alternative compression technique for effective infant CPR, especially for the rescuers with small hands or a weak grip. ©2014 Foundation Acta Paediatrica.

    Bystander resuscitation efforts, such as cardiopulmonary resuscitation (CPR) and use of an automatic external defibrillator (AED), save lives in cardiac arrest cases. School training in CPR and AED use may increase the currently low community rates of bystander resuscitation. The study objective was to determine the rates of CPR and AED training in Toronto secondary schools and to identify barriers to training and training techniques. This prospective study consisted of telephone interviews conducted with key school staff knowledgeable about CPR and AED teaching. An encrypted Web-based tool with prespecified variables and built-in logic was employed to standardize data collection. Of 268 schools contacted, 93% were available for interview and 83% consented to participate. Students and staff were trained in CPR in 51% and 80% of schools, respectively. Private schools had the lowest training rate (39%). Six percent of schools provided AED training to students and 47% provided AED training to staff. Forty-eight percent of schools had at least one AED installed, but 25% were unaware if their AED was registered with emergency services dispatch. Cost (17%), perceived need (11%), and school population size (10%) were common barriers to student training. Frequently employed training techniques were interactive (32%), didactic instruction (30%) and printed material (16%). CPR training rates for staff and students were moderate overall and lowest in private schools, whereas training rates in AED use were poor in all schools. Identified barriers to training include cost and student population size (perceived to be too small to be cost-effective or too large to be implemented). Future studies should assess the application of convenient and cost-effective teaching alternatives not presently in use.

    to compare the rate of return of spontaneous circulation (ROSC) and death after cardiac arrest, with and without the use of a metronome during cardiopulmonary resuscitation (CPR). case-control study nested in a cohort study including 285 adults who experienced cardiac arrest and received CPR in an emergency service. Data were collected using In-hospital Utstein Style. The control group (n=60) was selected by matching patients considering their neurological condition before cardiac arrest, the immediate cause, initial arrest rhythm, whether epinephrine was used, and the duration of CPR. The case group (n=51) received conventional CPR guided by a metronome set at 110 beats/min. Chi-square and likelihood ratio were used to compare ROSC rates considering p≤0.05. ROSC occurred in 57.7% of the cases, though 92.8% of these patients died in the following 24 hours. No statistically significant difference was found between groups in regard to ROSC (p=0.2017) or the occurrence of death (p=0.8112). the outcomes of patients after cardiac arrest with and without the use of a metronome during CPR were similar and no differences were found between groups in regard to survival rates and ROSC. comparar a taxa de retorno da circulação espontânea e óbito após parada cardiorrespiratória, com e sem a utilização do metrônomo durante ressuscitação cardiopulmonar. estudo caso-controle aninhado a estudo de coorte, com 285 adultos atendidos em parada cardíaca em um serviço de emergência e submetidos à ressuscitação cardiopulmonar.

    In cases of out-of hospital cardiac arrest (OHCA), falling to the ground can cause brain and neck trauma to the patient. We present a case of a man in his mid-60s who suffered from an OHCA resulting in a violent collapse. The patient received immediate cardiopulmonary resuscitation, but his spine was immobilised only after a large frontal haematoma was found. The resuscitation efforts resulted in return of spontaneous circulation and discharge from hospital. After this, doctors performed angioplasty, followed by a cardiopulmonary bypass. Later, CT scan examination reported a displaced and unstable fracture of the 6th vertebra without bone marrow involvement. The patient underwent a second operation. 40 days later, he was able to return home without sequela. This case shows the importance of analysing the circumstances of a fall, considering the possibility of two concomitant diagnoses and prioritising investigations and treatment.

    Although extracorporeal cardiopulmonary resuscitation (E-CPR) can result in survival after failed conventional CPR (C-CPR), no large, systematic comparison of pediatric E-CPR and continued C-CPR has been reported. Consecutive patients CPR events ≥10 minutes in duration reported to the Get With the Guidelines-Resuscitation registry between January 2000 and December 2011 were identified. Hospitals were grouped by teaching status and location. Primary outcome was survival to discharge. Regression modeling was performed, conditioning on hospital groups. A secondary analysis was performed with the use of propensity score matching. Of 3756 evaluable patients, 591 (16%) received E-CPR and 3165 (84%) received C-CPR only. Survival to hospital discharge and survival with favorable neurological outcome (Pediatric Cerebral Performance Category score of 1-3 or unchanged from admission) were greater for E-CPR (40% [237 of 591] and 27% [133 of 496]) versus C-CPR patients (27% [862 of 3165] and 18% [512 of 2840]). Odds ratios (ORs) for survival to hospital discharge and survival with favorable neurological outcome were greater for E-CPR versus C-CPR. After adjustment for covariates, patients receiving E-CPR had higher odds of survival to discharge (OR, 2.80; 95% confidence interval, 2.13-3.69; PCPR. This association persisted when analyzed by propensity score-matched cohorts (OR, 1.70; 95% confidence interval, 1.33-2.18; PCPR of ≥10 minutes duration, E-CPR was associated with improved survival to hospital discharge and survival with favorable neurological outcome compared with C-CPR. © 2015 American Heart Association, Inc.

    The quality of cardiopulmonary resuscitation (CPR) affects hemodynamics, survival, and neurological outcomes following pediatric cardiopulmonary arrest (CPA). Most health care professionals fail to perform CPR within established American Heart Association guidelines. To determine whether "just-in-time" (JIT) CPR training with visual feedback (VisF) before CPA or real-time VisF during CPA improves the quality of chest compressions (CCs) during simulated CPA. Prospective, randomized, 2 × 2 factorial-design trial with explicit methods (July 1, 2012, to April 15, 2014) at 10 International Network for Simulation-Based Pediatric Innovation, Research, & Education (INSPIRE) institutions running a standardized simulated CPA scenario, including 324 CPR-certified health care professionals assigned to 3-person resuscitation teams (108 teams). Each team was randomized to 1 of 4 permutations, including JIT training vs no JIT training before CPA and real-time VisF vs no real-time VisF during simulated CPA. The proportion of CCs with depth exceeding 50 mm, the proportion of CPR time with a CC rate of 100 to 120 per minute, and CC fraction (percentage CPR time) during simulated CPA. The quality of CPR was poor in the control group, with 12.7% (95% CI, 5.2%-20.1%) mean depth compliance and 27.1% (95% CI, 14.2%-40.1%) mean rate compliance. JIT training compared with no JIT training improved depth compliance by 19.9% (95% CI, 11.1%-28.7%; P 89.0%) in all groups. Combining both interventions showed the highest compliance with American Heart Association guidelines but was not significantly better than either intervention in isolation. The quality of CPR provided by health care professionals is poor. Using novel and practical technology, JIT training before CPA or real-time VisF during CPA, alone or in combination, improves compliance with American Heart Association guidelines for CPR that are associated with better outcomes. clinicaltrials.gov Identifier: NCT02075450.

    Conclusion: Although the initial resuscitation success rate was not affected by age, a longer time interval between the last medical staffs’ visit and the onset of resuscitation did result in a worse success rate in elderly patients. Our data suggest that more frequent staff visits to the elderly population during hospitalization could alter initial resuscitation results.

    Full Text Available Background: Performing immediate bystander Cardio Pulmonary Resuscitation (CPR is the most important factor that determines survival from cardiac arrest. Recommended mouth to mouth ventilation maneuver during CPR has led to lower rate of CPR performance in the population. Objectives: The present survey aimed to evaluate the willingness of nurses at Shiraz University of Medical Sciences for performing CPR versus chest-compression-only CPR. Patients and Methods: During a CPR course, we performed a survey on 25 nurses from Shiraz University of Medical Sciences, Iran. This survey included age and gender of the participants. In the first question, they were asked about their willingness to perform CPR with mouth to mouth breathing for witnessed cardiac arrest victims. In the second question, they were asked about their willingness to perform chest compression only for cardiac arrest victims. Results: Among the participating nurses, 96% were female with a mean age of 31 years. Only 40% were willing to perform CPR that requires mouth to mouth ventilation. On the other hand, 92% were willing to perform chest compression only without mouth to mouth ventilation. The mean age of the nurses who would do CPR was lower compared to those who would not. Conclusions: In this survey, we demonstrated that eliminating mouth to mouth ventilation maneuver could lead to markedly higher willingness to perform CPR for witnessed cardiac arrest victims in CPR trained nursing personnel. Our study is in agreement with other studies advocating that chest-compression-only CPR could lead to higher bystander resuscitation efforts.

    Full Text Available Abstract Non-occlusive colonic ischaemia is a recognized albeit rare entity related to low blood flow within the visceral circulation and in most reported cases the right colon was affected. This is the second case report in the literature of extensive colonic necrosis following cardiac arrest and cardiopulmonary resuscitation (CPR. A 83-year-old Caucasian woman was admitted to our hospital due to a low energy hip fracture. On her way to the radiology department she sustained a cardiac arrest. CPR started immediately and was successful. A few hours later, the patient developed increasing abdominal distension and severe metabolic acidocis. An abdominal multidetector computed tomography (MDCT scan was suggestive of intestinal ischaemia. At laparotomy, the terminal ileum was ischaemic and extensive colonic necrosis was found, sparing only the proximal third of the transverse colon. The rectum was also spared. The terminal ileum and the entire colon were resected and an end ileostomy was fashioned. Although the patient exhibited a transient improvement during the immediate postoperative period, she eventually died 24h later from multiple organ failure. Histology showed transmural colonic necrosis with no evidence of a thromboembolic process or vasculitis. Therefore, this entity was attributed to a low flow state within the intestinal circulation secondary to the cardiac arrest.

    Electroencephalogram reactivity (EEG-R) is a positive predictive factor for assessing outcomes in comatose patients. Most studies assess the prognostic value of EEG-R utilizing visual analysis; however, this method is prone to subjectivity. We sought to categorize EEG-R with a quantitative approach. We retrospectively studied consecutive comatose patients who had an EEG-R recording performed 1-3 days after cardiopulmonary resuscitation (CPR) or during normothermia after therapeutic hypothermia. EEG-R was assessed via visual analysis and quantitative analysis separately. Clinical outcomes were followed-up at 3-month and dichotomized as recovery of awareness or no recovery of awareness. A total of 96 patients met the inclusion criteria, and 38 (40%) patients recovered awareness at 3-month followed-up. Of 27 patients with EEG-R measured with visual analysis, 22 patients recovered awareness; and of the 69 patients who did not demonstrated EEG-R, 16 patients recovered awareness. The sensitivity and specificity of visually measured EEG-R were 58% and 91%, respectively. The area under the receiver operating characteristic curve for the quantitative analysis was 0.92 (95% confidence interval, 0.87-0.97), with the best cut-off value of 0.10. EEG-R through quantitative analysis might be a good method in predicting the recovery of awareness in patients with post-anoxic coma after CPR.

    Bystander cardiopulmonary resuscitation (CPR) is a crucial therapy for sudden cardiac arrest (SCA), yet rates of bystander CPR are low. This is especially the case for SCA occurring in the home setting, as family members of at-risk patients are often not CPR trained. To evaluate the feasibility of a novel hospital-based CPR education program targeted to family members of patients at increased risk for SCA. Prospective, multicenter, cohort study. Inpatient wards at 3 hospitals. Family members of inpatients admitted with cardiac-related diagnoses. Family members were offered CPR training via a proctored video-self instruction (VSI) program. After training, CPR skills and participant perspectives regarding their training experience were assessed. Surveys were conducted one month postdischarge to measure the rate of "secondary training" of other individuals by enrolled family members. At the 3 study sites, 756 subjects were offered CPR instruction; 280 agreed to training and 136 underwent instruction using the VSI program. Of these, 78 of 136 (57%) had no previous CPR training. After training, chest compression performance was generally adequate (mean compression rate 90 ± 26/minute, mean depth 37 ± 12 mm). At 1 month, 57 of 122 (47%) of subjects performed secondary training for friends or family members, with a calculated mean of 2.1 persons trained per kit distributed. The hospital setting offers a unique "point of capture" to provide CPR instruction to an important, undertrained population in contact with at-risk individuals.

    Full Text Available Background. Procurement of hearts from cardiopulmonary arrest and resuscitated (CPR donors for transplantation is suboptimal. We studied the influences of donor factors and regional wait times on CPR donor heart utilization. Methods. From UNOS database (1998 to 2012, we identified 44,744 heart donors, of which 4,964 (11% received CPR. Based on procurement of heart for transplantation, CPR donors were divided into hearts procured (HP and hearts not procured (HNP groups. Logistic regression analysis was used to identify predictors of heart procurement. Results. Of the 4,964 CPR donors, 1,427 (28.8% were in the HP group. Donor characteristics that favored heart procurement include younger age (25.5 ± 15 yrs versus 39 ± 18 yrs, P≤0.0001, male gender (34% versus 23%, P≤0.0001, shorter CPR duration (30 min, P≤0.0001, and head trauma (60% versus 15%. Among the 11 UNOS regions, the highest procurement was in Region 1 (37% and the lowest in Region 3 (24%. Regional transplant volumes and median waiting times did not influence heart procurement rates. Conclusions. Only 28.8% of CPR donor hearts were procured for transplantation. Factors favoring heart procurement include younger age, male gender, short CPR duration, and traumatic head injury. Heart procurement varied by region but not by transplant volumes or wait times.

    AIM: The aim of this survey was to establish prevalence of cardiopulmonary resuscitation (CPR) training within the last 5 years and reasons preventing training and initiation of CPR in Ireland as well as awareness of the emergency numbers. METHODS: An in-home omnibus survey was undertaken in 2008 with quota sampling reflecting the age, gender, social class and geography of Ireland. RESULTS: Of the 974 respondents, 23.5% had undergone CPR training in the previous 5 years with lower social class and age 65 years and older significantly less likely to be trained. The workplace was both a major source of awareness as well as training for those trained. In the untrained group lack of awareness of the need for CPR training was the most significant reason for non-training. Cost was not cited as a barrier. 88.9% of people gave a correct emergency number with geographical variation. Notably, the European emergency number 112 was not well known. CONCLUSION: Previous Irish and American population targets for CPR training have been surpassed in Ireland in 2008. New internationally agreed targets are now required. Meanwhile older people and those in lower socio-economic groups should be targeted for training. Awareness of at least one emergency number is very high in Ireland. Some geographical variation was found and this should be studied further.

    Dantrolene was introduced for treatment of malignant hyperthermia. It also has antiarrhythmic properties and may thus be an alternative to amiodarone for the treatment of ventricular fibrillation (VF). Aim of this study was to compare the return of spontaneous circulation (ROSC) with dantrolene and amiodarone in a pig model of cardiac arrest. VF was induced in anesthetized pigs. After 8 min of untreated VF, chest compressions and ventilation were started and one of the drugs (amiodarone 5 mg kg−1, dantrolene 2.5 mg kg−1 or saline) was applied. After 4 min of initial CPR, defibrillation was attempted. ROSC rates, hemodynamics and cerebral perfusion measurements were measured. Initial ROSC rates were 7 of 14 animals in the dantrolene group vs. 5 of 14 for amiodarone, and 3 of 10 for saline). ROSC persisted for the 120 min follow-up in 6 animals in the dantrolene group, 4 after amiodarone and 2 in the saline group (n.s.). Hemodynamics were comparable in both dantrolene group amiodarone group after obtaining ROSC. Dantrolene and amiodarone had similar outcomes in our model of prolonged cardiac arrest, However, hemodynamic stability was not significantly improved using dantrolene. Dantrolene might be an alternative drug for resuscitation and should be further investigated. PMID:28098197

    The concept of a medical emergency, i.e., a time when immediate action is required to stabilize and restore the vital functions, is absent in the tradition of ancient medicine, which seeks to cure the sick. The theoretical and conceptual development of a prompt medical assistance definitely owes much to the refinement of instruments and surgical techniques that were develop in the early modern age, allowing the extension of therapeutic action to "healthy" individuals who are suddenly life-threatened due to an accident or to some external events that affect their vital functions. But it is especially in the eighteenth century that the epistemic basis of medical emergency is structured, when the Enlightenment gave rise to the ethical and political imperative of public assistance that required the planning of first aid at multiple levels, and medicine developed the concept of life-saving treatment. In particular, eighteenth century medicine, studying systems to assure immediate relief to the victims of accidents-especially to the drowned-allowed the development of specific and methodological systems of resuscitation and emergency treatment.

    Objective:To establish a good recoverable rat model of cardiopulmonary bypass (CPB) to lay the foundation for studying the pathophysiology of CPB.Methods:Twenty adult male Sprague-Dawley rats weighing 480 g um via the right jugular vein and further transferred by a miniaturized roller pump to a hollow fiber oxgenator and back to the rat via the left carotid artery. Priming consisted of 8 ml of homologous blood and 6 ml of colloid. The surface of the hollow fiber oxgenator was 0.075 m2. Rats were catheterized and brought in bypass for 120 min at a flow rate of 100-120 ml/kg/min. Oxygen flow/ perfusion flow was 0. 8 to 1. 0, the mean arterial pressure (MAP) kept in 60-80 mmHg. Blood gas analysis, lactate dehydrogenase (LDH), and survival rate were examined subsequently.Results: All CPB rats recovered from the operative process without incident and remained uneventful within one week. Normal cardiac function after successful weaning was confirmed by electrocardiography and blood pressure measurements. MAP remained stable. The results of blood gas analysis at different time points were within a normal range. No significant haemolysis could be detected in the given time frame under bypass condition by using LDH.Conclusions: The rat model of CPB can principally simulate the clinical setting of human CPB. The nontransthoracic model is easy to establish and is associated with excellent recovery. This well reproducible model may open the field for various studies on pathophysiological process of CPB and also of systemic ischemia-reperfusion injury in vivo.

    Improved Cardiopulmonary Resuscitation (CPR) approaches will largely benefit the children in need. The constant peak displacement and constant peak force loading methods were analyzed on hard bed for pediatric CPR by an anatomically-detailed 10 year-old (YO) child thorax finite element (FE) model. The chest compression and rib injury risk were studied for children with various levels of thorax stiffness. We created three thorax models with different chest stiffness. Simulated CPR׳s in the above two conditions were performed. Three different compression rates were considered under the constant peak displacement condition. The model-calculated deflections and forces were analyzed. The rib maximum principle strains (MPS׳s) were used to predict the potential risk of rib injury. Under the constant peak force condition, the chest deflection ranged from 34.2 to 42.2mm. The highest rib MPS was 0.75%, predicted by the compliant thorax model. Under the normal constant peak displacement condition, the highest rib MPS was 0.52%, predicted by the compliant thorax model. The compression rate did not affect the highest rib MPS. Results revealed that the thoracic stiffness had great effects on the quality of CPR. To maintain CPR quality for various children, the constant peak displacement technique is recommended when the CPR is performed on the hard bed. Furthermore, the outcome of CPR in terms of rib strains and total work are not sensitive to the compression rate. The FE model-predicted high strains were in the ribs, which have been found to be vulnerable to CPR in the literature. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Non-technical skills, such as task management, leadership, situational awareness, communication and decision-making refer to cognitive, behavioural and social skills that contribute to safe and efficient team performance. The importance of these skills during cardiopulmonary resuscitation (CPR) is increasingly emphasised. Nonetheless, the relationship between non-technical skills and technical performance is poorly understood. We hypothesise that non-technical skills become increasingly important under stressful conditions when individuals are distracted from their tasks, and investigated the relationship between non-technical and technical skills under control conditions and when external stressors are present. In this simulator-based randomised cross-over study, 30 anaesthesiologists and anaesthesia residents from the VU University Medical Center, Amsterdam, the Netherlands, participated in two different CPR scenarios in random order. In one scenario, external stressors (radio noise and a distractive scripted family member) were added, while the other scenario without stressors served as control condition. Non-technical performance of the team leader and technical performance of the team were measured using the 'Anaesthetists' Non-technical Skill' score and a recently developed technical skills score. Analysis of variance and Pearson correlation coefficients were used for statistical analyses. Non-technical performance declined when external stressors were present (adjusted mean difference 3.9 points, 95% CI 2.4 to 5.5 points). A significant correlation between non-technical and technical performance scores was observed when external stressors were present (r=0.67, 95% CI 0.40 to 0.83, pskills of the team leader. This may have important implications for training of CPR teams. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017. All rights reserved.

    Advance cardiopulmonary resuscitation (CPR) decision-making and escalation of care discussions are variable in routine clinical practice. We aimed to explore physician barriers to advance CPR decision-making in an inpatient hospital setting and develop a pragmatic intervention to support clinicians to undertake and document routine advance care planning discussions. Two focus groups, which involved eight consultants and ten junior doctors, were conducted following a review of the current literature. A subsequent iterative consensus process developed two intervention elements: (i) an updated 'Goals of Patient Care' (GOPC) form and process; (ii) an education video and resources for teaching advance CPR decision-making and communication. A multidisciplinary group of health professionals and policy-makers with experience in systems development, education and research provided critical feedback. Three key themes emerged from the focus groups and the literature, which identified a structure for the intervention: (i) knowing what to say; (ii) knowing how to say it; (iii) wanting to say it. The themes informed the development of a video to provide education about advance CPR decision-making framework, improving communication and contextualising relevant clinical issues. Critical feedback assisted in refining the video and further guided development and evolution of a medical GOPC approach to discussing and recording medical treatment and advance care plans. Through an iterative process of consultation and review, video-based education and an expanded GOPC form and approach were developed to address physician and systemic barriers to advance CPR decision-making and documentation. Implementation and evaluation across hospital settings is required to examine utility and determine effect on quality of care.

    Posterior rib fractures are highly indicative of non-accidental trauma (NAT) in infants. Since 2000, the "two-thumbs" technique for cardiopulmonary resuscitation (CPR) of newborns and infants has been recommended by the American Heart Association (AHA). This technique is similar to the grip on an infant's thorax while shaking. Is it possible that posterior rib fractures in newborns and infants could be caused by the "two-thumbs" technique? Using computerized databases from three German children's hospitals, we identified all infants less than 12 months old who underwent professional CPR within a 10-year period. We included all infants with anterior-posterior chest radiographs taken after CPR. Exclusion criteria were sternotomy, osteopenia, various other bone diseases and NAT. The radiographs were independently reviewed by the Chief of Pediatric Radiology (MB) and a Senior Pediatrician, Head of the local Child Protection Team (IF). Eighty infants with 546 chest radiographs were identified, and 50 of those infants underwent CPR immediately after birth. Data concerning the length of CPR was available for 41 infants. The mean length of CPR was 11min (range: 1-180min, median: 3min). On average, there were seven radiographs per infant. A total of 39 infants had a follow-up radiograph after at least 10 days. No rib fracture was visible on any chest X-ray. The results of this study suggest rib fracture after the use of the "two-thumbs" CPR technique is uncommon. Thus, there should be careful consideration of abuse when these fractures are identified, regardless of whether CPR was performed and what technique used. The discovery of rib fractures in an infant who has undergone CPR without underlying bone disease or major trauma warrants a full child protection investigation. Copyright © 2014 Elsevier Ltd.

    Extracorporeal life support (ECLS) devices maintain the circulation and oxygenation of organs during acute right ventricular failure and cardiogenic shock, bypassing the lungs. A pulmonary embolism can cause this life-threatening condition. ECLS is a considerably less invasive treatment than surgical embolectomy. Whether to bridge embolectomy or for a therapeutic purpose, ECLS is used almost exclusively following failure of all other therapeutic options. From January 1, 2008 to June 30, 2014, five patients in cardiac arrest and with diagnosed pulmonary embolism (PE) were cannulated with the ECLS system. PE was diagnosed using computer tomography scanning or echocardiography. Cardiac arrest was witnessed in the hospital in all cases and CPR (cardiopulmonary resuscitation) was initiated immediately. Cannulation of the femoral vein and femoral artery was always performed under CPR conditions. Right heart failure regressed during the ECLS therapy, usually under a blood flow of 4-5 L/min after 48 hours. Three patients were weaned from ECLS and one patient became an organ donor. Finally, two of the five PE patients treated with ECLS were discharged from inpatient treatment without neurological dysfunction. The duration of ECLS therapy depends on the patient's condition. Irreversible damage to the organs after hypoxemia limits ECLS treatment and leads to futile multiorgan failure. Hemorrhages after thrombolysis and cerebral dysfunction were further complications. Veno-arterial cannulation for ECLS can be feasibly achieved and should be established during active CPR for cardiac arrest. In the case of PE, the immediate diagnosis and rapid implantation of the system are decisive for therapeutic success. © The Author(s) 2015.

    The performance of high-quality chest compressions with minimal interruptions is one of the most important elements of the "Chain of Survival." To evaluate the impact of a novel CPR PRO(®) (CPRO) device for manual chest compression on rescuer fatigue, pain, and cardiopulmonary resuscitation (CPR) quality. Randomized crossover trial of 24 health care professionals performing continuous chest compression CPR for 10 min with a CPRO device and conventional manual CPR (MCPR). Data about chest compressions were recorded using a manikin. Rescuers' physiologic signs were recorded before and after each session, and heart rate (HR) data were tracked continuously. Fatigue was assessed with ratings of perceived exertion, and pain questionnaire. All subjects completed 10 min of CPR with both methods. Significantly more rest breaks were taken during MCPR sessions (1.7 ± 2 vs. 0.21 ± 0.72). Subjects' perceived exertion was higher after MCPR, as well as the average (120.7 ± 16.8 vs. 110.8 ± 17.6) and maximal HR (134.3 ± 18.5 vs. 123.42 ± 16.5) during testing. Subjects reported more pain in the hands, especially the wrist, after performing MCPR. Average depth of compressions was higher with the CPRO device (4.6 ± 7.0 vs. 4.3 ± 7.9) and declined more slowly over time. Other CPR quality parameters, such as the correct position and complete release of pressure, were also better for CPRO CPR. CPRO device reduces rescuer fatigue and pain during continuous chest compression CPR, which results in a higher quality of CPR in a simulation setting. Copyright © 2013 Elsevier Inc.

    Bystander cardiopulmonary resuscitation (CPR) more than doubles the chance of surviving an out-of-hospital cardiac arrest. Recent data have shown considerable regional variation in bystander CPR rates across the Australian state of Victoria. This study aims to determine whether there is associated regional variation in rates of CPR training and willingness to perform CPR in these communities. We categorized each Victorian postcode as either a low or high bystander CPR region using data on adult, bystander-witnessed, out-of-hospital cardiac arrests of presumed cardiac etiology (n=7175) from the Victorian Ambulance Cardiac Arrest Registry. We then surveyed adult Victorians (n=404) and compared CPR training data of the respondents from low and high bystander CPR regions. Of the 404 adults surveyed, 223 (55%) resided in regions with low bystander CPR. Compared with respondents from high bystander CPR regions, respondents residing in regions with low bystander CPR had lower rates of CPR training (62% versus 75%, P=0.009) and lower self-ratings for their overall knowledge of CPR (76% versus 84%, P=0.04). There were no differences between the regions in their reasons for not having undergone CPR training or in their willingness to perform CPR. Rates of survival for bystander-witnessed, out-of-hospital cardiac arrests were significantly lower in low bystander CPR regions (15.7% versus 17.0%, Pbystander CPR in Victoria, Australia. Targeting these regions with CPR training programs may improve bystander CPR rates and out-of-hospital cardiac arrest outcomes. © 2017 The Authors.

    Full Text Available Background: Guidelines on performing cardiopulmonary resuscitation (CPR have been published from time to time, and formal training programs are conducted based on these guidelines. Very few data are available in world literature highlighting the impact of these trainings on CPR outcome. Aim: The aim of our study was to evaluate the impact of the American Heart Association (AHA-certified basic life support (BLS and advanced cardiac life support (ACLS provider course on the outcomes of CPR in our hospital. Materials and Methods : An AHA-certified BLS and ACLS provider training programme was conducted in our hospital in the first week of October 2009, in which all doctors in the code blue team and intensive care units were given training. The retrospective study was performed over an 18-month period. All in-hospital adult cardiac arrest victims in the pre-BLS/ACLS training period (January 2009 to September 2009 and the post-BLS/ACLS training period (October 2009 to June 2010 were included in the study. We compared the outcomes of CPR between these two study periods. Results: There were a total of 627 in-hospital cardiac arrests, 284 during the pre-BLS/ACLS training period and 343 during the post-BLS/ACLS training period. In the pre-BLS/ACLS training period, 52 patients (18.3% had return of spontaneous circulation, compared with 97 patients (28.3% in the post-BLS/ACLS training period (P < 0.005. Survival to hospital discharge was also significantly higher in the post-BLS/ACLS training period (67 patients, 69.1% than in the pre-BLS/ACLS training period (12 patients, 23.1% (P < 0.0001. Conclusion : Formal certified BLS and ACLS training of healthcare professionals leads to definitive improvement in the outcome of CPR.

    We studied the outcome of cardiopulmonary resuscitation (CPR) in patients undergoing coronary angiography (CA) and/or percutaneous coronary interventions (PCI). Of 51,985 CA and PCI patients treated between January 1, 1990, and December 31, 2000, 114 required CPR. Records were reviewed for relationships between patient characteristics and various procedures and short-term survival. Long-term survival was compared with that of a matched cohort of patients who did not have an arrest during catheterization and a matched cohort from the general Minnesota population. Over the 11-year period, the overall incidence of CPR was 21.9 per 10,000 procedures. This rate decreased from 33.9 per 10,000 before 1995 to 13.1 per 10,000 after 1995. Overall survival to hospital discharge after CPR was 56.1%. Survival to discharge was less frequent with a history of congestive heart failure, previous coronary artery bypass graft surgery, hemodynamic instability during the procedure, and with prolonged or emergent catheterizations. Pulseless electrical activity (versus asystole or ventricular fibrillation) indicated very poor short-term survival. Interestingly, short-term survival was not related to the extent of coronary artery disease. Long-term survival of patients who survived cardiac arrest was comparable to that of those who did not have arrest during catheterization. In conclusion, the incidence of periprocedural CPR during diagnostic or interventional coronary procedures decreased after 1995. Patients who received CPR in the cardiac catheterization lab have a remarkably frequent survival to hospital discharge rate. Long-term survival of these patients is only minimally reduced.

    Background Emergency medical practices are often team efforts. Training for various tasks and collaborations may be carried out in virtual environments. Although promising results exist from studies of serious games, little is known about the subjective reactions of learners when using multiplayer virtual world (MVW) training in medicine. Objective The objective of this study was to reach a better understanding of the learners’ reactions and experiences when using an MVW for team training of cardiopulmonary resuscitation (CPR). Methods Twelve Swedish medical students participated in semistructured focus group discussions after CPR training in an MVW with partially preset options. The students’ perceptions and feelings related to use of this educational tool were investigated. Using qualitative methodology, discussions were analyzed by a phenomenological data-driven approach. Quality measures included negotiations, back-and-forth reading, triangulation, and validation with the informants. Results Four categories characterizing the students’ experiences could be defined: (1) Focused Mental Training, (2) Interface Diverting Focus From Training, (3) Benefits of Practicing in a Group, and (4) Easy Loss of Focus When Passive. We interpreted the results, compared them to findings of others, and propose advantages and risks of using virtual worlds for learning. Conclusions Beneficial aspects of learning CPR in a virtual world were confirmed. To achieve high participant engagement and create good conditions for training, well-established procedures should be practiced. Furthermore, students should be kept in an active mode and frequent feedback should be utilized. It cannot be completely ruled out that the use of virtual training may contribute to erroneous self-beliefs that can affect later clinical performance. PMID:27986645

    To investigate (1) cardiopulmonary resuscitation (CPR) adequacy during simulated cardiac arrest of equipped football players and (2) whether protective football equipment impedes CPR performance measures. Exploratory crossover study performed on Laerdal SimMan 3 G interactive manikin simulator. Temple University/St Luke's University Health Network Regional Medical School Simulation Laboratory. Thirty BCLS-certified ATCs and 6 ACLS-certified emergency department technicians. Subjects were given standardized rescuer scenarios to perform three 2-minute sequences of compression-only CPR. Baseline CPR sequences were captured on each subject. Experimental conditions included 2-minute sequences of CPR either over protective football shoulder pads or under unlaced pads. Subjects were instructed to adhere to 2010 American Heart Association guidelines (initiation of compressions alone at 100/min to 51 mm). Dependent variables included average compression depth, average compression rate, percentage of time chest wall recoiled, and percentage of hands-on contact during compressions. Differences between subject groups were not found to be statistically significant, so groups were combined (n = 36) for analysis of CPR compression adequacy. Compression depth was deeper under shoulder pads than over (P = 0.02), with mean depths of 36.50 and 31.50 mm, respectively. No significant difference was found with compression rate or chest wall recoil. Chest compression depth is significantly decreased when performed over shoulder pads, while there is no apparent effect on rate or chest wall recoil. Although the clinical outcomes from our observed 15% difference in compression depth are uncertain, chest compression under the pads significantly increases the depth of compressions and more closely approaches American Heart Association guidelines for chest compression depth in cardiac arrest.

    Emergency medical practices are often team efforts. Training for various tasks and collaborations may be carried out in virtual environments. Although promising results exist from studies of serious games, little is known about the subjective reactions of learners when using multiplayer virtual world (MVW) training in medicine. The objective of this study was to reach a better understanding of the learners' reactions and experiences when using an MVW for team training of cardiopulmonary resuscitation (CPR). Twelve Swedish medical students participated in semistructured focus group discussions after CPR training in an MVW with partially preset options. The students' perceptions and feelings related to use of this educational tool were investigated. Using qualitative methodology, discussions were analyzed by a phenomenological data-driven approach. Quality measures included negotiations, back-and-forth reading, triangulation, and validation with the informants. Four categories characterizing the students' experiences could be defined: (1) Focused Mental Training, (2) Interface Diverting Focus From Training, (3) Benefits of Practicing in a Group, and (4) Easy Loss of Focus When Passive. We interpreted the results, compared them to findings of others, and propose advantages and risks of using virtual worlds for learning. Beneficial aspects of learning CPR in a virtual world were confirmed. To achieve high participant engagement and create good conditions for training, well-established procedures should be practiced. Furthermore, students should be kept in an active mode and frequent feedback should be utilized. It cannot be completely ruled out that the use of virtual training may contribute to erroneous self-beliefs that can affect later clinical performance.

    The case of a 29 year-old man who suffered a cardiac arrest due to a massive pulmonary embolism while he was undergoing surgical repair of a complex tibial plateau fracture is presented. After 70 min of unsuccessful cardiopulmonary resuscitation a bolus of 20 mg tenecteplase was given, with a return of spontaneous circulation 2 min after administration of the drug. Pulmonary embolism was subsequently demonstrated on a pulmonary angiogram. To our knowledge this is the first report to show that the use of a low dose of tenecteplase might be useful to achieve the return of spontaneous circulation in the resuscitation of patients with cardiac arrest secondary to massive pulmonary embolism. Previously reported cases are reviewed.

    We present two cases of a pericardial tear as a consequence of cardiopulmonary resuscitation involving chest compressions in fatal acute type A aortic dissection (AoD) with hemopericardium. For each case, postmortem computed tomography revealed a hematoma in the false lumen of the ascending aorta with a slight hemopericardium and a large left hemothorax, as well as focal pericardial dimpling and discontinuity around the left ventricle. At autopsy, we confirmed a convex lens-shape gaping pericardial tear at the left posterolateral site of the pericardium and a massive volume of bloody fluid in the left thoracic cavity. It has been hypothesized that the pericardium ruptured due to chest compressions during resuscitation in these cases of acute type A AoD with hemopericardium and that intrapericardial blood leakage through the pericardial tear resulted in a hemothorax.

    Between 1995 and 1998 the Berlin-Friedrichshain-Ambulance (BFA) started 785 cardiopulmonary resuscitations (CPR) (96,2 % adults). Registered are 498 (66,0 %) male and 257 (34,0 %) female persons at the age between 18 and 94 years (ys) (63,7 ± 16,7 ys). In 40,7 % the CPR has been initial successful. 37 patients have been discharged from the hospital. That means only 4,9 % of all registered adults (n = 755) have been discharged, it also means that 12,1 % of the initial successful treated...

    End-tidal carbon dioxide (ETCO(2)) measurements during cardiopulmonary resuscitation (CPR) reflect variable cardiac output over time, and low values have been associated with decreased survival. The goals of this review are to confirm and quantify this relationship and to determine the mean ETCO(2) value among patients with return of spontaneous circulation (ROSC) as an initial step toward determining an appropriate target for intervention during resuscitation in the absence of prospective data. The PubMed database was searched for the key words "end-tidal carbon dioxide" or "capnometry" or "capnography" and "resuscitation" or "return of spontaneous circulation." Randomized controlled trials, cohort studies, or case-control studies that reported ETCO(2) values for participants with and without ROSC were included. Twenty-seven studies met the inclusion criteria for qualitative synthesis. Twenty studies were included in determination of average ETCO(2) values. The mean ETCO(2) in participants with ROSC was 25.8 ± 9.8 mm Hg versus 13.1 ± 8.2 mm Hg (P = .001) in those without ROSC. Nineteen studies were included in a meta-analysis. The mean difference in ETCO(2) was 12.7 mm Hg (95% confidence interval: 10.3-15.1) between participants with and without ROSC (P levels of ETCO(2). The average ETCO(2) level of 25 mm Hg in participants with ROSC is notably higher than the threshold of 10 to 20 mm Hg to improve delivery of chest compressions. The ETCO(2) goals during resuscitation may be higher than previously suggested and further investigation into appropriate targets during resuscitation is needed to diminish morbidity and mortality after cardiorespiratory arrest. © The Author(s) 2014.

    This study was conducted to identify the educational effects of a blended e-learning program for graduating nursing students on self-efficacy, problem solving, and psychomotor skills for core basic nursing skills. A one-group pretest/posttest quasi-experimental design was used with 79 nursing students in Korea. The subjects took a conventional 2-week lecture-based practical course, together with spending an average of 60 minutes at least twice a week during 2 weeks on the self-guided e-learning content for basic cardiopulmonary resuscitation and defibrillation using Mosby's Nursing Skills database. Self- and examiner-reported data were collected between September and November 2014 and analyzed using descriptive statistics, paired t test, and Pearson correlation. The results showed that subjects who received blended e-learning education had improved problem-solving abilities (t = 2.654) and self-efficacy for nursing practice related to cardiopulmonary resuscitation and defibrillation (t = 3.426). There was also an 80% to 90% rate of excellent postintervention performance for the majority of psychomotor skills, but the location of chest compressions, compression rate per minute, artificial respiration, and verification of patient outcome still showed low levels of performance. In conclusion, blended E-learning, which allows self-directed repetitive learning, may be more effective in enhancing nursing competencies than conventional practice education.

    Conventional cardiopulmonary resuscitation (CPR) (chest compression and rescue breathing) has been recommended for pediatric out-of-hospital cardiac arrest (OHCA) because of the asphyxial nature of the majority of pediatric cardiac arrest events. However, the clinical effectiveness of additional rescue breathing (conventional CPR) compared with compression-only CPR in children is uncertain. This nationwide population-based study of pediatric OHCA patients was based on data from the All-Japan Utstein Registry. We included all pediatric patients who experienced OHCA in Japan from January 1, 2011, to December 31, 2012. The primary outcome was a favorable neurological state 1 month after OHCA defined as a Glasgow-Pittsburgh Cerebral Performance Category score of 1 to 2 (corresponding to a Pediatric Cerebral Performance Category score of 1-3). Outcomes were compared with logistic regression with uni- and multivariable modeling in the overall cohort and for a propensity-matched subset of patients. A total of 2157 patients were included; 417 received conventional CPR, 733 received compression-only CPR, and 1007 did not receive any bystander CPR. Among these patients, 213 (9.9%) survived with a favorable neurological status 1 month after OHCA, including 108/417 (25.9%) for conventional, 68/733 (9.3%) for compression-only, and 37/1007 (3.7%) for no-bystander CPR. In unadjusted analyses, conventional CPR was superior to compression-only CPR in neurologically favorable survival (odds ratio [OR] 3.42, 95% confidence interval [CI] 2.45-4.76; PCPR that was no longer statistically significant after multivariable adjustment (ORadjusted 1.52, 95% CI 0.93-2.49), and with further attenuation of the difference in a propensity-matched subset (OR 1.20, 95% CI 0.81-1.77). Both conventional and compression-only CPR were associated with higher odds for neurologically favorable survival compared with no-bystander CPR (ORadjusted 5.01, 95% CI 2.98-8.57, and ORadjusted 3.29, 95% CI 1

    Bystander-initiated cardiopulmonary resuscitation (CPR) increases patient survival after out-of-hospital cardiac arrest, but it is unknown to what degree bystander CPR remains positively associated with survival with increasing time to potential defibrillation. The main objective was to examine the association of bystander CPR with survival as time to advanced treatment increases. We studied 7623 out-of-hospital cardiac arrest patients between 2005 and 2011, identified through the nationwide Danish Cardiac Arrest Registry. Multiple logistic regression analysis was used to examine the association between time from 911 call to emergency medical service arrival (response time) and survival according to whether bystander CPR was provided (yes or no). Reported are 30-day survival chances with 95% bootstrap confidence intervals. With increasing response times, adjusted 30-day survival chances decreased for both patients with bystander CPR and those without. However, the contrast between the survival chances of patients with versus without bystander CPR increased over time: within 5 minutes, 30-day survival was 14.5% (95% confidence interval [CI]: 12.8-16.4) versus 6.3% (95% CI: 5.1-7.6), corresponding to 2.3 times higher chances of survival associated with bystander CPR; within 10 minutes, 30-day survival chances were 6.7% (95% CI: 5.4-8.1) versus 2.2% (95% CI: 1.5-3.1), corresponding to 3.0 times higher chances of 30-day survival associated with bystander CPR. The contrast in 30-day survival became statistically insignificant when response time was >13 minutes (bystander CPR vs no bystander CPR: 3.7% [95% CI: 2.2-5.4] vs 1.5% [95% CI: 0.6-2.7]), but 30-day survival was still 2.5 times higher associated with bystander CPR. Based on the model and Danish out-of-hospital cardiac arrest statistics, an additional 233 patients could potentially be saved annually if response time was reduced from 10 to 5 minutes and 119 patients if response time was reduced from 7 (the median

    Geographic clustering of bystander cardiopulmonary resuscitation (CPR) is associated with demographic and socioeconomic features of the community where out-of-hospital cardiac arrest (OHCA) occurred, although this association remains largely untested in rural areas. With a significant rural component and relative racial homogeneity, Kent County, Michigan, provides a unique setting to externally validate or identify new community features associated with bystander CPR. Using a large, countywide data set, we tested for geographic clustering of bystander CPR and its associations with community socioeconomic features. Secondary analysis of adult OHCA subjects (2010-2015) in the Cardiac Arrest Registry to Enhance Survival (CARES) data set for Kent County, Michigan. After linking geocoded OHCA cases to U.S. census data, we used Moran's I-test to assess for spatial autocorrelation of population-weighted cardiac arrest rate by census block group. Getis-Ord Gi statistic assessed for spatial clustering of bystander CPR and mixed-effects hierarchical logistic regression estimated adjusted associations between community features and bystander CPR. Of 1,592 subjects, 1,465 met inclusion criteria. Geospatial analysis revealed significant clustering of OHCA in more populated/urban areas. Conversely, bystander CPR was less likely in these areas (99% confidence) and more likely in suburban and rural areas (99% confidence). Adjusting for clinical, demographic, and socioeconomic covariates, bystander CPR was associated with public location (odds ratio [OR] = 1.19; 95% confidence interval [CI] = 1.03-1.39), initially shockable rhythms (OR = 1.48; 95% CI = 1.12-1.96), and those in urban neighborhoods (OR = 0.54; 95% CI = 0.38-0.77). Out-of-hospital cardiac arrest and bystander CPR are geographically clustered in Kent County, Michigan, but bystander CPR is inversely associated with urban designation. These results offer new insight into bystander CPR patterns in mixed urban and rural

    School cardiopulmonary resuscitation (CPR) training has become mandatory in many countries, but whether legislation has translated into implementation of CPR training is largely unknown. We assessed CPR training of students following 8 years of legislative mandates in Denmark. A nationwide cross-sectional survey of Danish school leadership (n=1240) and ninth-grade homeroom teachers (n=1381) was carried out for school year 2013-2014. Qualitative interviews and the Theory of Planned Behavior were used to construct the survey. Logistic regression models were employed to identify factors associated with completed CPR training. Information from 63.1% of eligible schools was collected: 49.3% (n=611) of leadership and 48.2% (n=665) of teachers responded. According to teachers, 28.4% (95% CI 25.0% to 32.0%) and 10.3% (95% CI 8.1% to 12.8%) of eligible classes had completed CPR and automated external defibrillator training, respectively. Among leadership, 60.2% (95% CI 56.2% to 64.1%) reported CPR training had occurred during the 3 years prior to the survey. Factors associated with completed CPR training included believing other schools were conducting training (odds ratio [OR] 9.68 [95% CI 4.65-20.1]), awareness of mandating legislation (OR 4.19 [95% CI 2.65-6.62]), presence of a school CPR training coordinator (OR 3.01 [95% CI 1.84-4.92]), teacher feeling competent to conduct training (OR 2.78 [95% CI 1.74-4.45]), and having easy access to training material (OR 2.08 [95% CI 1.57-2.76]). Despite mandating legislation, school CPR training has not been successfully implemented. Completed CPR training was associated with believing other schools were conducting training, awareness of mandating legislation, presence of a school CPR training coordinator, teachers teacher feeling competent to conduct training, and having easy access to training material. Facilitating these factors may increase rates of school CPR training. © 2017 The Authors. Published on behalf of the

    2012-01-01

    Without bystander cardiopulmonary resuscitation (CPR), cardiac arrest survival decreases 7%-10% for every minute of delay until defibrillation. Dispatcher-assisted CPR (D-CPR) has been shown to increase the rates of bystander CPR and cardiac arrest survival. Other reports suggest that the most critical component of bystander CPR is chest compressions with minimal interruption. Beginning with version 11.2 of the Medical Priority Dispatch System (MPDS) protocols, instructions for mouth-to-mouth ventilation (MTMV) and pulse check were removed and a compression-first pathway was introduced to facilitate rapid delivery of compressions. Additionally, unconscious choking and third-trimester pregnancy decision-making criteria were added in versions 11.3 and 12.0, respectively. However, the effects of these changes on time to first compression (TTFC) have not been evaluated. We sought to quantify the TTFC of MPDS versions 11.2, 11.3, and 12.0 for all calls identified as cardiac arrest on call intake that did not require MTMV instruction. Audio recordings of all D-CPR events for October 2005 through May 2010 were analyzed for TTFC. Differences in TTFC across versions were compared using the Kruskal-Wallis test. A total of 778 cases received D-CPR. Of these, 259 were excluded because they met criteria for MTMV (pediatric patients, allergic reaction, etc.), were missing data, or were not initially identified as cardiac arrest. Of the remaining 519 calls, the mean TTFC was 240 seconds, with no significant variation across the MPDS versions (p = 0.08). Following the removal of instructions for pulse check and MTMV, as well as other minor changes in the MPDS protocols, we found the overall TTFC to be 240 seconds with little variation across the three versions evaluated. This represents an improvement in TTFC compared with reports of an earlier version of MPDS that included pulse checks and MTMV instructions (315 seconds). However, the MPDS TTFC does not compare favorably with

    Background The influences of intrathoracic pressure (ITP) to hemodynamic and respiratory parameters during cardiopulmonary resuscitation (CPR) are confusing.In this research,we investigated the phasic changes of ITP during CPR and reveal the relationships among the hemodynamics,respiratory parameters,and ITP.Methods After 8 minutes of untreated ventricular fibrillation,which was induced in twenty intubated male domestic pigs,12 minutes of 30:2 CPR was performed.Continuous respiratory variables,hemodynamics,ITP and blood gas analysis were measured during CPR.After that,defibrillation was done and prognostic indicators after CPR was recorded.Results Average ITP at baseline was -(14.1±1.6) mmHg (1 mmHg=0.133 kPa).When gasping inspirations were going on,it decreased sharply to near -50 mmHg.ITP fluctuated up and down quickly from near -20 mmHg to 20 mmHg when compressions were performed.These phasic changes became mild as the CPR was performed,the contrast of high and low ITP decreased to (12.95±2.91) mmHg at the end of 12 minutes of CPR.Total alveolus minute volume decreased too,because of the decrease of compression and gasp related ventilations.Curve correlation was found between the tidal volume of compression and ITP:ITP=607.33/(1+3134×e-0.58×TV),(e:natural constant,R2=0.895).Negative correlations were found between the right atrial diastolic pressure and ITP (r=-0.753,P <0.01); and positive correlations were found between the coronary perfusion pressure and ITP (r=-0.626,P<0.01 ).Conclusions ITP is one of the key factors which can influence the prognosis of CPR.Correlations were found between the changes of ITP and the tidal volumes of compressions,right atrial diastolic pressure and coronary perfusion pressure during CPR.More positive ITP during compression and more negative during decompression were good to ventilation and perfusion.

    Full Text Available Objectives: To determine the correlation between the success rates of the cardiopulmonary cerebral resuscitation (CPCR and the team’s leader education and skill level in Shiraz, southern Iran. Method: This cross-sectional study was conducted during a 6-month period from October 2007 to March 2008 in Nemazee hospital of Shiraz. We included all the patients who underwent CPCR due to cardiopulmonary arrest in emergency room of Nemazee hospital during the study period. We recorded the rates of return of spontaneous circulation (ROSC and discharge rate (DR of all the patients. The correlation between these two parameters and the team leader’s education and skill level was evaluated. Results: Overall we included total number 600 patients among whom there were 349 men (58.1% and 251(41.8% women with mean age of 58.9±42.6. We found that 270 (45.1% patients had ROSC, while 330 (54.9% patients died. Overall 18 (6.6% patients were discharged from hospital (3% of all participants. We found that the ROSC was significantly higher in those with specialist leader (anesthesiologist or pediatrician when compared to those in whom CPCR was conducted by technicians (55.2% vs. 30.7%; p=0.001. Conclusion: Conducting CPCR by persons with higher medical degrees resulted in higher rate of ROSC but not in more discharge rate. Inspite of the fact that the rate of ROSC following CPCR was closely analogous to that of developed countries, discharge rate was lower. This indicates that in our region, much more attention needs to be paid to post-resuscitation care and organizing training programs and to cover more resuscitation by CPCR team, conducted by the specialists.

    Full Text Available Background: The survival rate of out-of-hospital cardiac arrest (OHCA victims in Lebanon is low. A national policy on resuscitation practice is lacking. This survey explored the practices of emergency physicians related to the resuscitation of OHCA victims in Lebanon. Methods: A sample of 705 physicians working in emergency departments (EDs was recruited and surveyed using the LimeSurvey software (Carsten Schmitz, Germany. Seventy-five participants responded, yielding 10.64% response rate. Results: The most important factors in the participants' decision to initiate or continue resuscitation were presence of pulse on arrival (93.2%, underlying cardiac rhythm (93.1%, the physician's ethical duty to resuscitate (93.2%, transport time to the ED (89%, and down time (84.9%. The participants were optimistic regarding the survival of OHCA victims (58.1% reporting > 10% survival and reported frequent resuscitation attempts in medically futile situations. The most frequently reported challenges during resuscitation decisions were related to pressure or presence of victim's family (38.8% and lack of policy (30%. Conclusion: In our setting, physicians often rely on well-established criteria for initiating/continuing resuscitation; however, their decisions are also influenced by cultural factors such as victim's family wishes. The findings support the need for a national policy on resuscitation of OHCA victims.

    The quality of cardiopulmonary resuscitation (CPR) has been recently shown to affect clinical outcome. The Resuscitation Outcomes Consortium (ROC) Prehospital Resuscitation Impedance Valve and Early Versus Delayed Analysis (PRIMED) trial showed no differences in outcomes with an active vs. sham impedance threshold device (ITD), a CPR adjunct that enhances circulation. It was hypothesized the active ITD would improve survival with favorable neurological outcomes in witnessed out-of-hospital cardiac arrest patients when used with high-quality CPR. Using the publicly accessible ROC PRIMED database, a post-hoc analysis was performed on all witnessed subjects with both compression rate and depth data (n=1,808) who received CPR within the study protocol definition of adequate CPR quality (compression rate 80-120/min and depth 4-6 cm; n=929). Demographics were similar between sham and active ITD groups. In witnessed subjects who received quality CPR, survival with favorable neurological function was 11.9% for the active ITD subjects (56/470) vs. 7.4% for the sham (34/459) (odds ratio 1.69 [95% confidence interval 1.08, 2.64]). There were no statistically significant differences for this primary outcome when CPR was performed outside the boundaries of the definition of adequate CPR quality. Multivariable models did not change these associations. An active ITD combined with adequate-quality conventional CPR has the potential to significantly improve survival after witnessed cardiac arrest. (Circ J 2016; 80: 2124-2132).

    To explore the experiences, emotions and coping skills among emergency medical technicians and emergency nurses after performing out-of-hospital cardiopulmonary resuscitation manoeuvres resulting in death. An exploratory qualitative research was performed. Seven emergency medical technicians and six emergency nurses were selected by non-probability sampling among emergency medical system workers. The meetings took place up to information saturation, achieved after six individual interviews and a focal group. The meetings were then transcribed and a manual and inductive analysis of the contents performed. After a failed resuscitation several short and long-term reactions appear. They can be negatives, such as sadness or uncertainty, or positives, such as the feeling of having done everything possible to save the patient's life. Emotional stress increases when ambulance staff have to talk with the deceased's family or when the patient is a child. The workers don't know of a coping strategy other than talking about their emotions with their colleagues. Death after a failed resuscitation can be viewed as a traumatic experience for rescuers. Being in contact with the suffering of others is an emotional, stress-generating factor with direct repercussions on the working and personal lives of emergency staff. Nevertheless, structured coping techniques are not common among those professionals. Copyright © 2016 Sociedad Española de Enfermería Intensiva y Unidades Coronarias (SEEIUC).

    As one of the cornerstones of modern cardiopulmonary resuscitation (CPR), ventilation received controversy and challenges in the past two decades. From 2000 to 2015, the changes in CPR guidelines of American Heart Association (AHA) showed that the position of ventilation declined gradually as compared to chest compressions. Chest compressions only CPR has been strongly advocated in recent years, especially in witnessed cardiogenic cardiac arrest (CA). Passive oxygenation and cardiocerebral resuscitation (CCR) also showed good effect in the early stage of cardiogenic CA. However, clinical validation in a larger context is still needed. An impedance threshold device (ITD) transiently blocks air from entering the lungs during recoil, decreases the intrathoracic pressure, facilitates venous return to the chest and increases coronary blood flow. However, the relevant research findings are not consistent, and the guidelines do not recommend routine use of ITD. Positive-pressure ventilation, which can increases intrathoracic pressure, affects the coronary perfusion pressure (CPP) and cerebral perfusion, is thought to be not only useless, but also has adverse effects within the first few minutes of CPR. This view is accepted by many scholars, however, ventilation is essential in late-start CPR, prolonged CPR and non-cardiogenic CA. Mechanical ventilation, especially special ventilation modes for CPR showed some prospects. Positive-pressure ventilation remains the gold standard in CPR in clinical practice at present. It was shown by existing research that hyperventilation significantly reduce the success rate of resuscitation, thus a consensus had been reached about avoiding hyperventilation. Currently, the number of studies on ventilation during CPR is very limited, and many of the conclusions are not consistent among studies. Therefore, more high-quality studies are needed in future to further clarify the application of ventilation during CPR.%作为现代心肺复苏

    An analysis of literature results reveals differences concerning the need for rescue breathing in lay-rescuer cardiopulmonary-resuscitation (CPR). Observational studies on large registries have shown improved survival rates with standard CPR (chest compressions and rescue breathing) compared to continuous chest compressions (CCC). This applies especially for cardiac arrests of non-cardiac origin or prolonged EMS-arrival times. In contrast a public program for lay-rescuers focusing on CCC lead to improved success rates of bystander-CPR, followed by improved survival rates. The 2010 ERC guidelines have resolved this controversy by integrating both aspects. CCC is recommended for everyone. Trained bystanders should use standard-CPR as method of choice. For dispatcher-assisted CPR the results are clear. Giving instructions for mouth-to-mouth ventilation is too complicated and time consuming, thus impairing survival rates. Therefore CCC is recommended for dispatcher-assisted CPR. © Georg Thieme Verlag Stuttgart · New York.

    This voluntary, anonymous questionnaire survey was performed to assess the willingness of Basic Life Support (BLS) participants to perform bystander cardiopulmonary resuscitation (CPR). A total of 55 dental students and 73 school teachers were assessed on their willingness to perform bystander CPR after completion of their BLS training. In general, only 29.0% of the total 128 participants said that they would offer to perform CPR under any cardiac arrest condition and 69.0% said that they would just offer to call the ambulance but they would not offer to perform CPR. When analyzed separately, only 16.4% of school teachers said that they would perform CPR as compared to 45.5% of dental students (p < 0.001). Knowing how to perform CPR does not necessarily translate into willingness to perform CPR.

    Survival from out-of-hospital resuscitation depends on the strength of each component of the chain of survival. We studied, on the scene, witnessed, nontraumatic resuscitations of patients older than 17 years. The influence of the chain of survival and potential predictors on survival was analyzed by logistic regression modeling. From 1030 patients, 139 survived to hospital discharge. Three prediction models of survival were developed from the perspective of the different contributors active in out-of-hospital resuscitation: model I, bystanders; model II, first responders; and model III, paramedics. Predictors for survival (with odds ratio) were: in model I (bystanders): emergency medical service (EMS) witnessed arrest (0.50), delay to basic cardiopulmonary resuscitation (CPR) (0.74/min) and delay to EMS arrival (0.87/min); in model II (first responders): initial recorded heart rhythm (0.02 for nonshockable rhythm), delay to basic CPR (0.71/min and 0.87/min for shockable and nonshockable rhythms) and to defibrillation (0.89/min), and in model III (paramedics): need for advanced CPR (4.74 for advanced CPR not-needed), initial recorded heart rhythm (0.05 for nonshockable rhythm), and delay to basic CPR (0.77/min and 0.72/min for shockable and nonshockable rhythms), to defibrillation and to advanced CPR for shockable rhythms (0.85/min), and to advanced CPR for nonshockable rhythm (0.85/min). The area under the receiver-operator characteristic curve for model I was 0.763, for model II was 0.848, and for model III was 0.896. Of survivors, 50% had restoration of circulation without need for advanced CPR. Three survival models for witnessed nontraumatic out-of-hospital resuscitation based on the information known by bystanders, first responders and paramedics explained survival with increasing precision. Early defibrillation can restore circulation without the need for advanced CPR. When advanced CPR is needed, its delay leads to a markedly reduced survival.

    Mild hypothermia improves survival and neurological recovery after cardiac arrest (CA) and cardiopulmonary resuscitation (CPR). However, the mechanism underlying this phenomenon is not fully elucidated. The aim of this study was to determine whether mild hypothermia alleviates early blood–brain barrier (BBB) disruption. We investigated the effects of mild hypothermia on neurologic outcome, survival rate, brain water content, BBB permeability and changes in tight junctions (TJs) and adherens junctions (AJs) after CA and CPR. Pigs were subjected to 8 min of untreated ventricular fibrillation followed by CPR. Mild hypothermia (33°C) was intravascularly induced and maintained at this temperature for 12 h, followed by active rewarming. Mild hypothermia significantly reduced cortical water content, decreased BBB permeability and attenuated TJ ultrastructural and basement membrane breakdown in brain cortical microvessels. Mild hypothermia also attenuated the CPR-induced decreases in TJ (occludin, claudin-5, ZO-1) and AJ (VE-cadherin) protein and mRNA expression. Furthermore, mild hypothermia decreased the CA- and CPR-induced increases in matrix metalloproteinase-9 (MMP-9) and vascular endothelial growth factor (VEGF) expression and increased angiogenin-1 (Ang-1) expression. Our findings suggest that mild hypothermia attenuates the CA- and resuscitation-induced early brain oedema and BBB disruption, and this improvement might be at least partially associated with attenuation of the breakdown of TJ and AJ, suppression of MMP-9 and VEGF expression, and upregulation of Ang-1 expression.

    To determine the frequency of cardiopulmonary resuscitation education using high-fidelity patient simulators during pediatric residency training. Randomized controlled trial. Suburban tertiary care children's hospital residency training program. Twenty-four second year pediatric residents. Twenty-four second year pediatric residents were randomized into two study groups, 12 residents in each. Both groups completed a formal resuscitation training course utilizing lectures, skill stations, and six scenarios on high-fidelity patient stimulators. Group A was retested on three scenarios 4 months after training and group B was similarly retested 8 months after training. Time intervals from induction of a clinical problem to its definitive management were recorded for each resident. Residents were also asked to complete surveys following each episode of training and testing. The mean time intervals, for group A, to start effective bag mask ventilation and chest compressions in response to apnea and cardiac arrest were 17.75 secs (± 3.39 secs) and 23.42 secs (± 9.33 secs), respectively. These were significantly shorter than 32.7 secs (± 18.6 secs) and 81.2 secs (± 74.9 secs), for group B, respectively (p training, when compared to 4 months after training. These results may indicate that residents require more frequent training than currently recommended.

    Cardiopulmonary resuscitation (CPR) artifacts caused by chest compressions and ventilations interfere with the rhythm diagnosis of automated external defibrillators (AED). CPR must be interrupted for a reliable diagnosis. However, pauses in chest compressions compromise the defibrillation success rate and reduce perfusion of vital organs. The removal of the CPR artifacts would enable compressions to continue during AED rhythm analysis, thereby increasing the likelihood of resuscitation success. We have estimated the CPR artifact using only the frequency of the compressions as additional information to model it. Our model of the artifact is adaptively estimated using a least mean-square (LMS) filter. It was tested on 89 shockable and 292 nonshockable ECG samples from real out-of-hospital sudden cardiac arrest episodes. We evaluated the results using the shock advice algorithm of a commercial AED. The sensitivity and specificity were above 95% and 85%, respectively, for a wide range of working conditions of the LMS filter. Our results show that the CPR artifact can be accurately modeled using only the frequency of the compressions. These can be easily registered after small changes in the hardware of the CPR compression pads.

    Poor quality cardiopulmonary resuscitation (CPR) predicts adverse outcome. During invasive cardiac procedures automated-CPR (A-CPR) may help maintain effective resuscitation. The use of A-CPR following in-hospital cardiac arrest (IHCA) remains poorly described. Firstly, we aimed to assess the efficiency of healthcare staff using A-CPR in a cardiac arrest scenario at baseline, following re-training and over time (Scenario-based training). Secondly, we studied our clinical experience of A-CPR at our institution over a 2-year period, with particular emphasis on the details of invasive cardiac procedures performed, problems encountered, resuscitation rates and in-hospital outcome (AutoPulse-CPR Registry). Scenario-based training: Forty healthcare professionals were assessed. At baseline, time-to-position device was slow (mean 59 (±24) s (range 15-96s)), with the majority (57%) unable to mode-switch. Following re-training time-to-position reduced (28 (±9) s, pCPR Registry: 285 patients suffered IHCA, 25 received A-CPR. Survival to hospital discharge following conventional CPR was 28/260 (11%) and 7/25 (28%) following A-CPR. A-CPR supported invasive procedures in 9 patients, 2 of whom had A-CPR dependant circulation during transfer to the catheter lab. A-CPR may provide excellent haemodynamic support and facilitate simultaneous invasive cardiac procedures. A significant learning curve exists when integrating A-CPR into clinical practice. Further studies are required to better define the role and effectiveness of A-CPR following IHCA. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available Abstract Background Cardiac arrest is the leading cause of mortality in Canada, and the overall survival rate for out-of-hospital cardiac arrest rarely exceeds 5%. Bystander cardiopulmonary resuscitation (CPR has been shown to increase survival for cardiac arrest victims. However, bystander CPR rates remain low in Canada, rarely exceeding 15%, despite various attempts to improve them. Dispatch-assisted CPR instructions have the potential to improve rates of bystander CPR and many Canadian urban communities now offer instructions to callers reporting a victim in cardiac arrest. Dispatch-assisted CPR instructions are recommended by the International Guidelines on Emergency Cardiovascular Care, but their ability to improve cardiac arrest survival remains unclear. Methods/Design The overall goal of this study is to better understand the factors leading to successful dispatch-assisted CPR instructions and to ultimately save the lives of more cardiac arrest patients. The study will utilize a before-after, prospective cohort design to specifically: 1 Determine the ability of 9-1-1 dispatchers to correctly diagnose cardiac arrest; 2 Quantify the frequency and impact of perceived agonal breathing on cardiac arrest diagnosis; 3 Measure the frequency with which dispatch-assisted CPR instructions can be successfully completed; and 4 Measure the impact of dispatch-assisted CPR instructions on bystander CPR and survival rates. The study will be conducted in 19 urban communities in Ontario, Canada. All 9-1-1 calls occurring in the study communities reporting out-of-hospital cardiac arrest in victims 16 years of age or older for which resuscitation was attempted will be eligible. Information will be obtained from 9-1-1 call recordings, paramedic patient care reports, base hospital records, fire medical records and hospital medical records. Victim, caller and system characteristics will be measured in the study communities before the introduction of dispatch

    Out-of-hospital cardiac arrest (OHCA) is a major cause of death worldwide. Cardiac arrest can be subdivided into asphyxial and non asphyxial etiologies. An asphyxia arrest is caused by lack of oxygen in the blood and occurs in drowning and choking victims and in other circumstances. A non asphyxial arrest is usually a loss of functioning cardiac electrical activity. Cardiopulmonary resuscitation (CPR) is a well-established treatment for cardiac arrest. Conventional CPR includes both chest compressions and 'rescue breathing' such as mouth-to-mouth breathing. Rescue breathing is delivered between chest compressions using a fixed ratio, such as two breaths to 30 compressions or can be delivered asynchronously without interrupting chest compression. Studies show that applying continuous chest compressions is critical for survival and interrupting them for rescue breathing might increase risk of death. Continuous chest compression CPR may be performed with or without rescue breathing. To assess the effects of continuous chest compression CPR (with or without rescue breathing) versus conventional CPR plus rescue breathing (interrupted chest compression with pauses for breaths) of non-asphyxial OHCA. We searched the Cochrane Central Register of Controlled Trials (CENTRAL; Issue 1 2017); MEDLINE (Ovid) (from 1985 to February 2017); Embase (1985 to February 2017); Web of Science (1985 to February 2017). We searched ongoing trials databases including controlledtrials.com and clinicaltrials.gov. We did not impose any language or publication restrictions. We included randomized and quasi-randomized studies in adults and children suffering non-asphyxial OHCA due to any cause. Studies compared the effects of continuous chest compression CPR (with or without rescue breathing) with interrupted CPR plus rescue breathing provided by rescuers (bystanders or professional CPR providers). Two authors extracted the data and summarized the effects as risk ratios (RRs), adjusted risk

    The occurrence of an unexpected sudden death puts the witnesses of this event in a situation of high emotional impact. The benefit to allow the families of victims to dispense the first resuscitation techniques has been emphasized. However, little data exist on the emotional impact of a cardio-respiratory arrest outside the hospital on the witness, who is often a close family member. Recently, we investigated the presence of psychological distress and the factors influencing it, in the active practice of basic resuscitation gestures by the witnesses guided by the operator 112. Resuscitation by a person not belonging to the medical corps seems not to be devoid of psychological impact. Indeed, the presence of psychological distress is observed for most of witnesses questioned 6 to 10 days after the call but also 3 months later. This work highlights therefore the importance of identifying the coping strategies involved, in order to promote potentially beneficial strategies and limit the trauma associated with this type of event.

    In order to improve the quality of our Emergency Medical Services (EMS), to raise bystander cardiopulmonary resuscitation rates and thereby meet what is becoming a universal standard in terms of quality of emergency services, we decided to implement systematic dispatcher-assisted or telephone-CPR (T-CPR) in our medical dispatch center, a non-Advanced Medical Priority Dispatch System. The aim of this article is to describe the implementation process, costs and results following the introduction of this new "quality" procedure. This was a prospective study. Over an 8-week period, our EMS dispatchers were given new procedures to provide T-CPR. We then collected data on all non-traumatic cardiac arrests within our state (Vaud, Switzerland) for the following 12 months. For each event, the dispatchers had to record in writing the reason they either ruled out cardiac arrest (CA) or did not propose T-CPR in the event they did suspect CA. All emergency call recordings were reviewed by the medical director of the EMS. The analysis of the recordings and the dispatchers' written explanations were then compared. During the 12-month study period, a total of 497 patients (both adults and children) were identified as having a non-traumatic cardiac arrest. Out of this total, 203 cases were excluded and 294 cases were eligible for T-CPR. Out of these eligible cases, dispatchers proposed T-CPR on 202 occasions (or 69% of eligible cases). They also erroneously proposed T-CPR on 17 occasions when a CA was wrongly identified (false positive). This represents 7.8% of all T-CPR. No costs were incurred to implement our study protocol and procedures. This study demonstrates it is possible, using a brief campaign of sensitization but without any specific training, to implement systematic dispatcher-assisted cardiopulmonary resuscitation in a non-Advanced Medical Priority Dispatch System such as our EMS that had no prior experience with systematic T-CPR. The results in terms of T-CPR delivery

    Full Text Available Background and Aims: Cardiac arrest has multifactorial aetiology and the outcome depends on timely and correct interventions. We decided to investigate the circumstances, incidence and outcome of cardiopulmonary resuscitation (CPR at a tertiary hospital in India, in relation to various factors, including extensive basic life support and advanced cardiac life support training programme for all nurses and doctors. Methods: It has been over a decade and a half with periodical updates and implementation of newer guidelines prepared by various societies across the world about CPR for both in-hospital and out-of hospital cardiac arrests (IHCA and OHCA. We conducted a prospective study wherein all cardiac arrests reported in the hospital consecutively for 12 months were registered for the study and followed their survival up to 1-year. Statistical analysis was performed by using Chi-square test for significant differences in proportions applied to various parameters of the study. Results: The main outcome measures were; (following CPR return of spontaneous circulation, survival for 24 h, survival from 24 h to 6 weeks or discharge, alive at 1-year. For survivors, an assessment was made about their cerebral performance and overall performance and accordingly graded. All these data were tabulated. Totally 419 arrests were reported in the hospital, out of which 413 were in-hospital arrests. Out of this 260 patients were considered for resuscitation, we had about 27 survivors at the end of 1-year follow-up (10.38%. Conclusion: We conclude by saying there are many factors involved in good clinical outcomes following IHCAs and these variable factors need to be researched further.

    It is unclear how much the length of a cardiopulmonary resuscitation (CPR) training program can be reduced without ruining its effectiveness. The authors aimed to compare CPR skills 6 months and 1 year after training between shortened chest compression-only CPR training and conventional CPR training. Participants were randomly assigned to either the compression-only CPR group, which underwent a 45-minute training program consisting of chest compressions and automated external defibrillator (AED) use with personal training manikins, or the conventional CPR group, which underwent a 180-minute training program with chest compressions, rescue breathing, and AED use. Participants' resuscitation skills were evaluated 6 months and 1 year after the training. The primary outcome measure was the proportion of appropriate chest compressions 1 year after the training. A total of 146 persons were enrolled, and 63 (87.5%) in the compression-only CPR group and 56 (75.7%) in the conventional CPR group completed the 1-year evaluation. The compression-only CPR group was superior to the conventional CPR group regarding the proportion of appropriate chest compression (mean ± SD = 59.8% ± 40.0% vs. 46.3% ± 28.6%; p = 0.036) and the number of appropriate chest compressions (mean ± SD = 119.5 ± 80.0 vs. 77.2 ± 47.8; p = 0.001). Time without chest compression in the compression-only CPR group was significantly shorter than that in the conventional CPR group (mean ± SD = 11.8 ± 21.1 seconds vs. 52.9 ± 14.9 seconds; p training program appears to help the general public retain CPR skills better than the conventional CPR training program.

    In the event of a cardiac arrest, emergency medical dispatchers (EMDs) play a critical role by providing telephone-assisted cardiopulmonary resuscitation (T-CPR) to laypersons. The aim of our investigation was to describe compliance with the T-CPR protocol, the performance of the laypersons in a simulated T-CPR situation, and the communication between laypersons and EMDs during these actions. We conducted a retrospective observational study by analysing 20 recorded video and audio files. In a simulation, EMDs provided laypersons with instructions following T-CPR protocols. These were then analysed using a mixed method with convergent parallel design. If the EMDs complied with the T-CPR protocol, the laypersons performed the correct procedures in 71% of the actions. The single most challenging instruction of the T-CPR protocol, for both EMDs and laypersons, was airway control. Mean values for compression depth and frequency did not reach established guideline goals for CPR. Proper application of T-CPR protocols by EMDs resulted in better performance by laypersons in CPR. The most problematic task for EMDs as well for laypersons was airway management. The study results did not establish that the quality of communication between EMDs and laypersons performing CPR in a cardiac arrest situation led to statistically different outcomes, as measured by the quality and effectiveness of the CPR delivered.

    Drawings made by training children into cardiopulmonary resuscitation (CPR) during the special education week called "School otherwise" can be used as non-verbal means of expression and communication to assess the impact of such training. We analyzed the questionnaires and drawings completed by 327 schoolchildren in different stages of education. After a brief overview of the basic life support (BLS) steps and after watching a video presenting the dynamic performance of the BLS sequence, subjects were asked to complete a questionnaire and make a drawing to express main CPR messages. Questionnaires were filled completely in 97.6 % and drawings were done in 90.2 % cases. Half of the subjects had already witnessed a kind of medical emergency and 96.94 % knew the correct "112" emergency phone number. The drawings were single images (83.81 %) and less cartoon strips (16.18 %). Main themes of the slogans were "Save a life!", "Help!", "Call 112!", "Do not be indifferent/insensible/apathic!" through the use of drawings interpretation, CPR trainers can use art as a way to build a better relation with schoolchildren, to connect to their thoughts and feelings and obtain the highest quality education.

    The survival rate of patients with out-of-hospital cardiac arrest is low, and measures to improve the quality of cardiopulmonary resuscitation (CPR) during ambulance transportation are desirable. We designed a stabilization device, and in a randomized crossover trial we found performing CPR in a moving ambulance with the device (MD) could achieve better efficiency than that without the device (MND), but the efficiency was lower than that in a non-moving ambulance (NM). To evaluate whether a modified version of the stabilization device, can promote further the quality of CPR during ambulance transportation. Participants of the previous study were recruited, and they performed CPR for 10 minutes in a moving ambulance with the modified version of the stabilization device (MVSD). The primary outcomes were effective chest compressions and no-flow fraction recorded by a skill-reporter manikin. The secondary outcomes included back pain, physiological parameters, and the participants' rating about the device after performing CPR. The overall effective compressions in 10 minutes were 86.4±17.5% for NM, 60.9±14.6% for MND, 69.7±22.4% for MD, and 86.6%±13.2% for MVSD (pambulance to a level similar to that in a non-moving condition without increasing the severity of back pain.

    Our objective was to compare the impact of a training program in pediatric cardiopulmonary resuscitation (CPR) on the knowledge and skills of in-service and preservice nurses at prespecified time points. This repeated-measures quasiexperimental study was conducted in the pediatric emergency and ICU of a tertiary care teaching hospital between January and March 2011. We assessed the baseline knowledge and skills of nursing staff (in-service nurses) and final year undergraduate nursing students (preservice nurses) using a validated questionnaire and a skill checklist, respectively. The participants were then trained on pediatric CPR using standard guidelines. The knowledge and skills were reassessed immediately after training and at 6 weeks after training. A total of 74 participants-28 in-service and 46 preservice professionals-were enrolled. At initial assessment, in-service nurses were found to have insignificant higher mean knowledge scores (6.6 versus 5.8, P = 0.08) while the preservice nurses had significantly higher skill scores (6.5 versus 3.2, P nurses performing better in knowledge test (10.5 versus 9.1, P = 0.01) and the preservice nurses performing better in skill test (9.8 versus 7.4, P skills of in-service and preservice nurses in pediatric CPR improved with training. In comparison to preservice nurses, the in-service nurses seemed to retain knowledge better with time than skills.

    Objective To compare the effects of vasopressin and adrenaline on cerebral resuscitation in rats. Method Sixty male SD rats were used to set the animal model of cardiac arrest and were randomly (random number) divided into 4 groups (n = 15/group): sham operation group (sham-gro), negative control group (neg-gro), vasopressin group (vas-gro) and adrenaline group (adr-gro). Blood pressure was recorded, and brain tissue samples were obtained. Results There was no significant difference in the recovery rate between vas-gro and adr-gro 30 min after resuscitation (P <0.05). The mean blood pressure in vasgro was higher than that in adr-gro within 30 min (1,2, 5, 10, 20, 30 min) after restoration of spontaneous circulation. The measured MDA, SOD and GSH were significantly different (P < 0.05) between each two groups among vas-gro, sham-gro and adr-gro. Conclusions The recovery rate was similar between vasopressin group and adrenaline group during cardiopulmonary resuscitation in rats. However, vasopressin can to maintain the mean arterial pressure at a higher level after resuscitation, which can the increase the cerebral perfusion and reduce brain cell damage.%目的 比较血管加压素与肾上腺素对大鼠脑复苏效果的研究.方法 60只雄性SD大鼠建立心搏骤停模型,随机(随机数字法)分为4组(n=15/组):假手术组(sham operated group,shamgro)、阴性对照组(neg-gro)、血管加压素组(vas-gro)、肾上腺素组(adr-gro).分别记录血压变化,并取大鼠脑组织标本.结果 在复苏30 min后vas-gro与adr-gro复苏成功率差异无统计学意义(P>0.05);在自主循环恢复的30 min内(1,2,5,10,20,30 min)vas-gro的平均动脉压均高于adr-gro;测得MDA,SOD,GSH的量vas-gro,sham-gro,adr-gro互相之间差异有统计学意义(P<0.05).结论 血管加压素与肾上腺素在大鼠心肺复苏过程中成功率相近,但血管加压素能维持复苏后平均动脉压在较高水平,继而会更好的增加脑灌注,减轻脑细胞损伤.

    The appropriate duration of cardiopulmonary resuscitation (CPR) for pediatric out-of-hospital cardiac arrests (OHCAs) remains unclear and may differ based on initial rhythm. We aimed to determine the relationship between the duration of prehospital CPR by emergency medical services (EMS) personnel and post-OHCA outcomes. We analyzed the records of 12 877 pediatric patients who experienced OHCAs (CPR duration was defined as the time from CPR initiation by EMS personnel to prehospital return of spontaneous circulation (ROSC) or to hospital arrival when prehospital ROSC was not achieved during prehospital CPR efforts. The rates of 30-day survival and 30-day CPC 1 to 2 were 9.1% (n=1167) and 2.5% (n=325), respectively. Prehospital EMS-initiated CPR duration was significantly and inversely associated with 30-day outcomes (adjusted odds ratio for 1-minute increments: 0.94, 95% confidence interval: 0.93-0.95 for survival; adjusted odds ratio: 0.90, 95% confidence interval: 0.88-0.92 for CPC 1-2). The duration of prehospital EMS-initiated CPR, beyond which the chance for favorable outcomes diminished to CPR durations beyond which the chance for 30-day survival with CPC 1 to 2 diminished to CPR, the prehospital CPR duration, beyond which the chance for favorable outcome diminished to CPR duration for pediatric OHCAs was independently and inversely associated with 30-day favorable outcomes. The duration of prehospital EMS-initiated CPR, beyond which the chance for 30-day favorable outcomes diminished to CPR duration to achieve this proportion of outcomes differed based on initial rhythm. Further research is required to elucidate appropriate CPR duration for pediatric OHCAs, including in-hospital CPR time. URL: https://clinicaltrials.gov.

    Research investigating design effects of instructional tools for learning Basic Life Support (BLS) is almost non-existent. To demonstrate the design of instructional tools matter. The effect of spatial contiguity, a design principle stating that people learn more deeply when words and corresponding pictures are placed close (i.e., integrated) rather than far from each other on a page was investigated on task cards for learning Cardiopulmonary Resuscitation (CPR) during reciprocal peer learning. A randomized controlled trial. A total of 111 students (mean age: 13 years) constituting six intact classes learned BLS through reciprocal learning with task cards. Task cards combine a picture of the skill with written instructions about how to perform it. In each class, students were randomly assigned to the experimental group or the control. In the control, written instructions were placed under the picture on the task cards. In the experimental group, written instructions were placed close to the corresponding part of the picture on the task cards reflecting application of the spatial contiguity principle. One-way analysis of variance found significantly better performances in the experimental group for ventilation volumes (P=.03, ηp2=.10) and flow rates (P=.02, ηp2=.10). For chest compression depth, compression frequency, compressions with correct hand placement, and duty cycles no significant differences were found. This study shows that the design of instructional tools (i.e., task cards) affects student learning. Research-based design of learning tools can enhance BLS and CPR education.

    Background Residents who live in neighborhoods that are primarily African-American, Latino, or poor are more likely to have an out-of-hospital cardiac arrest (OHCA), less likely to receive cardiopulmonary resuscitation (CPR), and less likely to survive. No prior studies have been conducted to understand the contributing factors that may decrease the likelihood of residents learning and performing CPR in these neighborhoods. The goal of this study was to identify barriers and facilitators to learning and performing CPR in three low-income, “high-risk” predominantly African American, neighborhoods in Columbus, Ohio. Methods and Results Community-Based Participatory Research (CBPR) approaches were used to develop and conduct six focus groups in conjunction with community partners in three target high-risk neighborhoods in Columbus, Ohio in January-February 2011. Snowball and purposeful sampling, done by community liaisons, was used to recruit participants. Three reviewers analyzed the data in an iterative process to identify recurrent and unifying themes. Three major barriers to learning CPR were identified and included financial, informational, and motivational factors. Four major barriers were identified for performing CPR and included fear of legal consequences, emotional issues, knowledge, and situational concerns. Participants suggested that family/self-preservation, emotional, and economic factors may serve as potential facilitators in increasing the provision of bystander CPR. Conclusion The financial cost of CPR training, lack of information, and the fear of risking one's own life must be addressed when designing a community-based CPR educational program. Using data from the community can facilitate improved design and implementation of CPR programs. PMID:24021699

    The 2010 American Heart Association Guidelines for Cardiopulmonary Resuscitation (CPR) recommend that chest compression be rotated every 2 min to prevent rescuer fatigue. However, the quality of chest compression using 2-min switched CPR tends to decrease rapidly due to rescuer fatigue. We aimed to compare the effectiveness of use of 2-min switched CPR and rescuer-limited CPR (the person performing compressions is allowed to switch with another rescuer prior to 2 min if feeling fatigued) in the setting of inhospital cardiac arrest. Using a randomised cross-over trial design, 90 medical students were grouped into pairs to perform four cycles of 2-min switched CPR and rescuer-limited CPR (495 s per technique). During each trial, the total number of compressions performed, mean depth of compression and proportion of effective compressions performed (compression depth >5 mm) were recorded for identification of significant differences and changes in pulse rate and RR were measured to determine the extent of exhaustion. Compared with 2-min switched CPR, the mean compression was deeper (51 vs 47 mm, pCPR. Subgroup analysis by 30-s unit showed more consistent compression quality during rescuer-limited CPR. No significant differences in change in pulse rate and RR were found between the two techniques. Rescuer-limited CPR yields a greater number of effective compressions and more consistent quality of CPR than 2-min switched CPR. Rescuer-limited CPR might be a suitable alternative for treating inhospital cardiac arrest. Published by the BMJ Publishing Group Limited.

    Despite increasing use of extracorporeal cardiopulmonary resuscitation (E-CPR) for treatment of refractory cardiac arrest patients, prognosis remains dismal, often resulting in brain-death. However, clinical assessment of brain-death occurence is difficult in post-cardiac arrest patients, sedated, paralyzed, under mild therapeutic hypothermia (MTH). Our objective was to assess the usefulness of Bispectral-Index (BIS) monitoring at bedside for an early detection of brain-death occurrence in refractory cardiac arrest patients treated by E-CPR. This prospective study was performed in an intensive care unit of an university hospital. Forty-six patients suffering from refractory cardiac arrest treated by E-CPR were included. BIS was continuously recorded during ICU hospitalization. Clinical brain-death was confirmed when appropriate by EEG and/or cerebral CT angiography. Twenty-nine patients evolved into brain-death and had average BIS values under MTH and after rewarming (temperature ≥35°C) of 4 (0-47) and 0 (0-82), respectively. Among these, 11 (38%) entered into a procedure of organs donation. Among the 17 non-brain-dead patients, the average BIS values at admission and after rewarming were 39 (0-65) and 59 (22-82), respectively. Two patients had on admission a BIS value equal to zero and evolved to a poor prognostic (CPC 4) and died after care limitations. BIS values were significantly different between patients who developed brain death and those who did not. In both groups, no differences were observed between the AUCs of ROC curves for BIS values under MTH and after rewarming (respectively 0.86 vs 0.83, NS). Initial values of BIS could be used as an assessment tool for early detection of brain-death in refractory cardiac arrest patients treated by mild therapeutic hypothermia and E-CPR.

    The primary purpose of this study was to compare two, shorter, self-directed methods of cardiopulmonary resuscitation (CPR) education for healthcare professionals (HCP) to traditional training with a focus on the trainee's ability to perform two-person CPR. First-year medical students with either no prior CPR for HCP experience or prior training greater than 5 years were randomized to complete one of three courses: 1) HeartCode BLS System, 2) BLS Anytime, or 3) Traditional training. Only data from the adult CPR skills testing station was reviewed via video recording by certified CPR instructors and the Laerdal PC Skill Reporter software program (Laerdal Medical, Stavanger, Norway). There were 180 first-year medical students who met inclusion criteria: 68 were HeartCode BLS System, 53 BLS Anytime group, and 59 traditional group Regarding two-person CPR, 57 (84%) of Heartcode BLS students and 43 (81%) of BLS Anytime students were able to initiate the switch compared to 39 (66%) of traditional course students (p = 0.04). There were no significant differences in the quality of chest compressions or ventilations between the three groups. There was a trend for a much higher CPR skills testing pass rate for the traditional course students. However, failure to "clear to analyze or shock" while using the AED was the most common reason for failure in all groups. The self-directed learning groups not only had a high level of success in initiating the "switch" to two-person CPR, but were not significantly different from students who completed traditional training.

    本文对中西方心肺复苏的历史进行了回顾,分析了古代心肺复苏各种方法的特点与内涵,及其对现代心肺复苏的启示,认为在心肺复苏时体位放置与脑复苏的关系,体温调整在复苏中的意义,人工呼吸的实施要点,四肢与腹部等胸外器官在人工循环中的作用,以及直肠等新的给药途径等方面,应汲取东西方古代复苏的精华,这对指导心肺复苏的理论研究和临床实践有重要意义。%This paper reviewed the key point of cardiopulmonary resuscitation (CPR) history in the east and west world, and analyzed the characteristics and connotation of the various CPR methods and its meaning and the inspiration for the modern CPR study. Many of ancient methods should be pay more attention, such as the patient’s position in the recovery of the brain, body temperature modulation in the CPR, the methods of the artiifcial respiration, and the function of limbs and abdomen in the artiifcial circulation, new administration of the rectum and other aspects. That was important to guide the theoretical study and clinical practice.

    We compared the time to initiation of cardiopulmonary resuscitation (CPR) by lay responders and/or first responders alerted either via Short Message Service (SMS) or by using a mobile application-based alert system (APP). The Ticino Registry of Cardiac Arrest collects all data about out-of-hospital cardiac arrests (OHCAs) occurring in the Canton of Ticino. At the time of a bystander's call, the EMS dispatcher sends one ambulance and alerts the first-responders network made up of police officers or fire brigade equipped with an automatic external defibrillator, the so called "traditional" first responders, and - if the scene was considered safe - lay responders as well. We evaluated the time from call to arrival of traditional first responders and/or lay responders when alerted either via SMS or the new developed mobile APP. Over the study period 593 OHCAs have occurred. Notification to the first responders network was sent via SMS in 198 cases and via mobile APP in 134 cases. Median time to first responder/lay responder arrival on scene was significantly reduced by the APP-based system (3.5 [2.8-5.2]) compared to the SMS-based system (5.6 [4.2-8.5] min, p 0.0001). The proportion of lay responders arriving first on the scene significantly increased (70% vs. 15%, pfirst responder or of a lay responder determined a higher survival rate. The mobile APP system is highly efficient in the recruitment of first responders, significantly reducing the time to the initiation of CPR thus increasing survival rates.

    Junior doctors are often the "first line" doctors called to attend to patients in cardiac arrest. We performed an anonymous questionnaire study from October 2008 to December 2008 to assess the knowledge, attitude and skill of cardiopulmonary resuscitation among junior doctors in Hospital Universiti Sains Malaysia and Hospital Raja Perempuan Zainab II. Out of the 100 questionnaire forms sent out, 70 were returned completed. The majority (85.8%) stated that they were not confident of managing a resuscitation case. There was a statistically significant (p<0.001) association between duration of clinical practice and confidence level. Up to 77.1% said that BLS should be re-certified every two years.

    Full Text Available AIMS: To determine whether the introduction of the Universal Form of Treatment Options (the UFTO, as an alternative approach to Do Not Attempt Cardiopulmonary Resuscitation (DNACPR orders, reduces harms in patients in whom a decision not to attempt cardiopulmonary resuscitation (CPR was made, and to understand the mechanism for any observed change. METHODS: A mixed-methods before-and-after study with contemporaneous case controls was conducted in an acute hospital. We examined DNACPR (103 patients with DNACPR orders in 530 admissions and UFTO (118 decisions not to attempt resuscitation in 560 admissions practice. The Global Trigger Tool was used to quantify harms. Qualitative interviews and observations were used to understand mechanisms and effects. RESULTS: RATE OF HARMS IN PATIENTS FOR WHOM THERE WAS A DOCUMENTED DECISION NOT TO ATTEMPT CPR WAS REDUCED: Rate difference per 1000 patient-days was 12.9 (95% CI: 2.6-23.2, p-value=0.01. There was a difference in the proportion of harms contributing to patient death in the two periods (23/71 in the DNACPR period to 4/44 in the UFTO period (95% CI 7.8-36.1, p-value=0.006. Significant differences were maintained after adjustment for known confounders. No significant change was seen on contemporaneous case control wards. Interviews with clinicians and observation of ward practice revealed the UFTO helped provide clarity of goals of care and reduced negative associations with resuscitation decisions. CONCLUSIONS: Introducing the UFTO was associated with a significant reduction in harmful events in patients in whom a decision not to attempt CPR had been made. Coupled with supportive qualitative evidence, this indicates the UFTO improved care for this vulnerable group.

    Full Text Available Cardiopulmonary resuscitation (CPR is one of the most important skills that every body must know it in medical services. In educational hospitals, the (Newly-arrived residents are in first cell for management of victims, specially in emergency rooms and at nights. Their knowledge and ability for successful CPR have a direct relation with prevalence of total mortality and morbidity. This research has assessed the knowledge and attitude of the new residents about CPR, and for answering to this question: "Is the CPR workshops necessary for all of the new residents in the beginning of their courses". All of the 506 new residents were examined simultaneously in 2 separate years with a questionnaire consist of 50 questions about their CPR secence and skills and 8 questions about their attitude in CPR. These informations were analyzed by SPSS and EPI6 softwares. The mean correct answers were 55%±11.8. The best results were about arrythmias (68.6% and airway management (63.6% and the worst were about IV access (43.1% and pediatric CPR (31.5%. These findings were similar in 2 sequential years.

    Full Text Available Abstract Background Overall survival rates for out-of-hospital cardiac arrest rarely exceed 5%. While bystander cardiopulmonary resuscitation (CPR can increase survival for cardiac arrest victims by up to four times, bystander CPR rates remain low in Canada (15%. Most cardiac arrest victims are men in their sixties, they usually collapse in their own home (85% and the event is witnessed 50% of the time. These statistics would appear to support a strategy of targeted CPR training for an older population that is most likely to witness a cardiac arrest event. However, interest in CPR training appears to decrease with advancing age. Behaviour surrounding CPR training and performance has never been studied using well validated behavioural theories. Methods/Design The overall goal of this study is to conduct a survey to better understand the behavioural factors influencing CPR training and performance in men and women 55 years of age and older. The study will proceed in three phases. In phase one, semi-structured qualitative interviews will be conducted and recorded to identify common categories and themes regarding seeking CPR training and providing CPR to a cardiac arrest victim. The themes identified in the first phase will be used in phase two to develop, pilot-test, and refine a survey instrument based upon the Theory of Planned Behaviour. In the third phase of the project, the final survey will be administered to a sample of the study population over the telephone. Analyses will include measures of sampling bias, reliability of the measures, construct validity, as well as multiple regression analyses to identify constructs and beliefs most salient to seniors' decisions about whether to attend CPR classes or perform CPR on a cardiac arrest victim. Discussion The results of this survey will provide valuable insight into factors influencing the interest in CPR training and performance among a targeted group of individuals most susceptible to

    Background During pediatric cardiopulmonary resuscitation (CPR), vasoactive drug preparation for continuous infusion is both complex and time-consuming, placing children at higher risk than adults for medication errors. Following an evidence-based ergonomic-driven approach, we developed a mobile device app called Pediatric Accurate Medication in Emergency Situations (PedAMINES), intended to guide caregivers step-by-step from preparation to delivery of drugs requiring continuous infusion. Objective The aim of our study was to determine whether the use of PedAMINES reduces drug preparation time (TDP) and time to delivery (TDD; primary outcome), as well as medication errors (secondary outcomes) when compared with conventional preparation methods. Methods The study was a randomized controlled crossover trial with 2 parallel groups comparing PedAMINES with a conventional and internationally used drugs infusion rate table in the preparation of continuous drug infusion. We used a simulation-based pediatric CPR cardiac arrest scenario with a high-fidelity manikin in the shock room of a tertiary care pediatric emergency department. After epinephrine-induced return of spontaneous circulation, pediatric emergency nurses were first asked to prepare a continuous infusion of dopamine, using either PedAMINES (intervention group) or the infusion table (control group), and second, a continuous infusion of norepinephrine by crossing the procedure. The primary outcome was the elapsed time in seconds, in each allocation group, from the oral prescription by the physician to TDD by the nurse. TDD included TDP. The secondary outcome was the medication dosage error rate during the sequence from drug preparation to drug injection. Results A total of 20 nurses were randomized into 2 groups. During the first study period, mean TDP while using PedAMINES and conventional preparation methods was 128.1 s (95% CI 102-154) and 308.1 s (95% CI 216-400), respectively (180 s reduction, P=.002).

    Although both recorded lectures and serious games have been used to pretrain health professionals before simulation training on cardiopulmonary resuscitation, they have never been compared. The aim of this study was to compare an online course and a serious game for pretraining medical students before simulation-based mastery learning on the management of sudden cardiac arrest. A randomised controlled trial. Participants were pretrained using the online course or the serious game on day 1 and day 7. On day 8, each participant was evaluated repeatedly on a scenario of cardiac arrest until reaching a minimum passing score. Department of Simulation in Healthcare in a French medical faculty. Eighty-two volunteer second-year medical students participated between June and October 2016 and 79 were assessed for primary outcome. The serious game used was Staying Alive, which involved a 3D realistic environment, and the online course involved a PowerPoint lecture. The median total training time needed for students to reach the minimum passing score on day 8. This same outcome was also assessed 4 months later. The median training time (interquartile range) necessary for students to reach the minimum passing score was similar between the two groups: 20.5 (15.8 to 30.3) minutes in the serious game group versus 23 (15 to 32) minutes in the online course group, P = 0.51. Achieving an appropriate degree of chest compression was the most difficult requirement to fulfil for students in both groups. Four months later, the median training time decreased significantly in both groups, but no correlation was found at an individual level with the training times observed on day 8. The serious game used in this study was not superior to an online course to pretrain medical students in the management of a cardiac arrest. The absence of any correlation between the performances of students evaluated during two training sessions separated by 4 months suggests that some elements in the

    OBJECTIVE To evaluate the effect of serum brain natriuretic peptide levels on brain damage at the early stage after cardiopulmonary resuscitation (CPR). METHODS There were 34 patients with restoration of spontaneous circulation after successful CPR.After 2 months of successful cardiopulmonary resuscitation (CPR) , patients with GCS score ≥ 12 were mild brain damage (I group, male 6 cases, female 8 cases); GCS score 9 ≤ GCS ≤ 11 were moderate brain damage (II group, male 4 cases, female 6 cases); GCS score 3 ≤ GCS ≤ 8 were severe brain damage (Ⅲ group, male 5 cases, and female 5 cases) . Control group was consisted of 15 healthy volunteers. All of the patients' venous blood were respectively collected and BNP was detected by enzyme linked immunosorbent assay at 2, 8, 12, 24 and 48 h after restoring of independent circulation. RESULTS Compared the age, sex, start time of cardiac arrest to recovery in cardiopulmonary resuscitation (CPR) group and control group, differences were not statistically significant (P> 0.05); at 2, 8, 12, 24 and 48 h, serum BNP levels in I , II and Ⅲ groups were significantly higher than the control group (P < 0.05); And in the trail group, I group was significantly lower than the II group (P< 0.05); II group and was significantly lower than the HI group (P< 0.05). CONCLUSION Serum BNP levels can reflect cardiopulmonary resuscitation (CPR) early after HPC ischemia brain damage, and for the assessment of the recovery cardiopulmonary resuscitation (CPR) has an important value.%目的 探讨血清脑钠肽(BNP)对心肺复苏后脑损伤的预测的价值.方法 34例经心肺复苏后自主循环恢复的患者,以心肺复苏成功后2个月格拉斯哥昏迷评分(GCS)≥12为轻度脑损伤(Ⅰ组),男6例,女8例;9≤GCS≤11为中度脑损伤(Ⅱ组),男4例,女6例;3≤GCS≤8为重度脑损伤(Ⅲ组),男5例,女5例.另外选取14例健康者(女8例,男6例)作为对照组.所有患者均在自主循环恢复后2、8

Methods 60 rats were randomized into 5 groups. Rat models of cardiopulmonary resuscitation were established. Rhodioside was administrated before or after resuscitation at different time. When return of spontaneous circulation sustained for 2 h, heart function was assessed by echocardiography. Cardiac myocytes of adult rats were isolated and cultured with or without Rhodioside, atorvastatin and irbesartan. RT - PCR and Western blot were used to evaluate the expression change of SERCA2a and CaN - Aβ. Results Echocardiography revealed that heart function in model groups was significantly lower than that in false surgery group. Further analysis demonstrated that when given Rhodioside before resuscitation, better improvement of heart function could be observed. RT - PCR and Western blot demonstrated that Rhodioside could down - regulate CaN - Aβ and up - regulate SERCA2a. Conclusion Rhodioside could improve heart function after resuscitation in rats possibly associated with the regulation of SERCA2a and CaN - Aβ.

    The availability of extracorporeal membrane oxygenation (ECMO) assisted cardiopulmonary resuscitation (E-CPR), for use in refractory out-of hospital cardiac arrest (OHCA), is increasing. In parallel, some countries have developed uncontrolled donation after circulatory determination of death (uDCDD) programs using ECMO to preserve organs for transplantation purposes. When facing a refractory OHCA, how does the medical team choose between initiating ECMO as part of an E-CPR protocol or ECMO as part of a uDCDD protocol? To answer these questions we conducted a literature review on E-CPR compared to uDCDD protocols using ECMO and analyzed the raised ethical issues. Our analysis reveals that the inclusion criteria in E-CPR and uDCDD protocols are similar. There may be a non-negligible risk of including patients in a uDCDD protocol, when the patient might have been saved by the use of E-CPR. In order to avoid the fatal error of letting a saveable patient die, safeguards are necessary. We recommend: (1) the development of internationally accepted termination of resuscitation guidelines that would have to be satisfied prior to inclusion of patients in any uDCDD protocol, (2) the choice regarding modalities of ongoing resuscitation during transfer should be focused on the primary priority of attempting to save the life of patients, (3) only centers of excellence in life-saving resuscitation should initiate or maintain uDCDD programs, (4) E-CPR should be clinically considered first before the initiation of any uDCDD protocol, and (5) there should be no discrimination in the availability of access to E-CPR.

    Objective To evaluate the clinical efficacy of extracorporeal cardiopulmonary resuscitation (CPR) for treatment of adult cardiac arrest patients. Methods The clinical records of 20 adult cardiac arrest patients who were admitted to our hospital from January 2011 to June 2013 were retrospectively analyzed. Results The most common cause of cardiac arrest in these patients was cardiovascular disease (40%), followed by trauma (25%). Return of spontaneous circulation had a high success rate of 50%, while cerebral resuscitation was associated with a low success rate of 10%only. Patients who underwent successful CPR had a significantly shorter time to CPR and establishment of an artificial airway and significantly higher epinephrine usage than those who underwent unsuccessful cardiopulmonary resuscitation (P0.05).Conclusion The shorter time to CPR and establishment of an artificial airway and higher adrenaline usage can improve the success rate of treatment for cardiac arrest patients.%目的:分析体外心肺复苏技术救治成人心搏骤停患者的临床效果。方法回顾性分析我院2011年1月至2013年6月收治的20例心搏骤停成人患者的临床资料。结果成年心搏骤停患者最主要的发病原因是心血管系统疾病,其次为外伤,分别占总发病人数的40%和25%;ROSC具有较高的成功率,为50%,而脑复苏成功则具有较低的成功率,仅为10%;成功组患者的心肺复苏开始时间、建立人工气道时间均明显比失败组短,肾上腺素用量明显比失败组多,二者相比具有显著的统计学差异(P0.05)。结论体外心肺复苏技术救治心搏骤停患者时尽可能短的心肺复苏开始时间、人工气道建立时间及较多的肾上腺素用量能够提高救治成功率。

    Cardiac arrest has a high mortality in children. To improve the performance of cardiopulmonary resuscitation, it is essential to disseminate the international recommendations and the training of health professionals and the general population in resuscitation. This article summarises the 2015 European Paediatric Cardiopulmonary Resuscitation recommendations, which are based on a review of the advances in cardiopulmonary resuscitation and consensus in the science and treatment by the International Council on Resuscitation. The Spanish Paediatric Cardiopulmonary Resuscitation recommendations, developed by the Spanish Group of Paediatric and Neonatal Resuscitation, are an adaptation of the European recommendations, and will be used for training health professionals and the general population in resuscitation. This article highlights the main changes from the previous 2010 recommendations on prevention of cardiac arrest, the diagnosis of cardiac arrest, basic life support, advanced life support and post-resuscitation care, as well as reviewing the algorithms of treatment of basic life support, obstruction of the airway and advanced life support.

    In 2007, the Ishikawa Medical Control Council initiated the continuous quality improvement (CQI) project for telephone-assisted cardiopulmonary resuscitation (telephone-CPR), which included instruction on chest-compression-only CPR, education on how to recognise out-of-hospital cardiac arrests (OHCAs) with agonal breathing, emesis and convulsion, recommendations for on-line or redialling instructions and feedback from emergency physicians. This study aimed to investigate the effect of this project on the incidence of bystander CPR and the outcomes of OHCAs. The baseline data were prospectively collected on 4995 resuscitation-attempted OHCAs, which were recognised or witnessed by citizens rather than emergency medical technicians during the period of February 2004 to March 2010. The incidence of telephone-CPR and bystander CPR, as well as the outcomes of the OHCAs, was compared before and after the project. The incidence of telephone-CPR and bystander CPR significantly increased after the project (from 42% to 62% and from 41% to 56%, respectively). The incidence of failed telephone-CPR due to human factors significantly decreased from 30% to 16%. The outcomes of OHCAs significantly improved after the projects. A multiple logistic regression analysis revealed that the CQI project is one of the independent factors associated with one-year (1-Y) survival with favourable neurological outcomes (odds ratio=1.81, 95% confidence interval=1.20-2.76). The CQI project for telephone-CPR increased the incidence of bystander CPR and improved the outcome of OHCAs. A CQI project appeared to be essential to augment the effects of telephone-CPR.

    2010-08-01

    Full Text Available Abstract Background Plate and screw fixation is a recent addition to the sternal wound treatment armamentarium. Patients undergoing cardiac and major vascular surgery have a higher risk of postoperative arrest than other elective patients. Those who undergo sternotomy for either cardiac or major vascular procedures are at a higher risk of postoperative arrest. Sternal plate design allows quick access to the mediastinum facilitating open cardiac massage, but chest compressions are the mainstay of re-establishing cardiac output in the event of arrest. The response of sternal plates and the chest wall to compressions when plated has not been studied. The safety of performing this maneuver is unknown. This study intends to demonstrate compressions are safe after sternal plating. Methods We investigated the effect of chest compressions on the plated sternum using a human cadaveric model. Cadavers were plated, an arrest was simulated, and an experienced physician performed a simulated resuscitation. Intrathoracic pressure was monitored throughout to ensure the plates encountered an appropriate degree of force. The hardware and viscera were evaluated for failure and trauma respectively. Results No hardware failure or obvious visceral trauma was observed. Rib fractures beyond the boundaries of the plates were noted but the incidence was comparable to control and to the fracture incidence after resuscitation previously cited in the literature. Conclusions From this work we believe chest compressions are safe for the patient with sternal plates when proper plating technique is used. We advocate the use of this life-saving maneuver as part of an ACLS resuscitation in the event of an arrest for rapidly re-establishing circulation.

    Full Text Available Purpose. Rapid advanced airway management is important in maternal cardiopulmonary resuscitation (CPR. This study aimed to compare intubation performances among Pentax-AWS (AWS, Glidescope (GVL, and Macintosh laryngoscope (MCL during mechanical chest compression in 15° and 30° left lateral tilt. Methods. In 19 emergency physicians, a prospective randomized crossover study was conducted to examine the three laryngoscopes. Primary outcomes were the intubation time and the success rate for intubation. Results. The median intubation time using AWS was shorter than that of GVL and MCL in both tilt degrees. The time to visualize the glottic view in GVL and AWS was significantly lower than that of MCL (all P<0.05, whereas there was no significant difference between the two video laryngoscopes (in 15° tilt, P=1; in 30° tilt, P=0.71. The progression of tracheal tube using AWS was faster than that of MCL and GVL in both degrees (all P<0.001. Intubations using AWS and GVL showed higher success rate than that of Macintosh laryngoscopes. Conclusions. The AWS could be an appropriate laryngoscope for airway management of pregnant women in tilt CPR considering intubation time and success rate.

    Mechanical chest compression devices have been developed to facilitate continuous delivery of high-quality cardiopulmonary resuscitation (CPR). Despite promising hemodynamic data, evidence on clinical outcomes remains inconclusive. With the completion of 3 randomized controlled trials, we conduct a meta-analysis on the effect of in-field mechanical versus manual CPR on clinical outcomes after out-of-hospital cardiac arrest. With a systematic search (PubMed, Web of Science, EMBASE, and the Cochrane Libraries), we identified all eligible studies (randomized controlled trials and nonrandomized studies) that compared a CPR strategy including an automated mechanical chest compression device with a strategy of manual CPR only. Outcome variables were survival to hospital admission, survival to discharge, and favorable neurologic outcome. Twenty studies (n=21,363) were analyzed: 5 randomized controlled trials and 15 nonrandomized studies, pooled separately. For survival to admission, the pooled estimate of the randomized controlled trials did not indicate a difference (odds ratio 0.94; 95% confidence interval 0.84 to 1.05; P=.24) between mechanical and manual CPR. In contrast, meta-analysis of nonrandomized studies demonstrated a benefit in favor of mechanical CPR (odds ratio 1.42; 95% confidence interval 1.21 to 1.67; PCPR guidelines (2000 versus 2005) and the CPR strategy (P=.27). Survival to discharge and neurologic outcome did not differ between strategies. Although there are lower-quality, observational data that suggest that mechanical CPR used at the rescuer's discretion could improve survival to hospital admission, the cumulative high-quality randomized evidence does not support a routine strategy of mechanical CPR to improve survival or neurologic outcome. These findings are irrespective of the endorsed CPR guidelines during the study periods. Copyright © 2015 American College of Emergency Physicians. Published by Elsevier Inc. All rights reserved.

    Objective To investigate the effect of cardiopulmonary resuscitation in emergency treatment of sudden death.Methods The clinical data of 150 emergency death patients from January 2012 to December 2015 in People’s Hospital of Daxing District were retrospectively analyzed, epidemiological information including:gender, age, previous history of sudden death in patients with aura symptoms before sudden death, incentives, workplace, season occurrence and time characteristics of sudden death, and clinical effect of cardio-pulmonary resuscitation (CPR) was also analyzed.Results Among those patients, number of males was higher than that of females. The incidence of sudden death was higher in patients of following groups: between 60~79 years old, had history of cardiovascular disease, had premonitory symptom or with known risk factors; and it was higher in winter and spring than other seasons (P<0.05). As to the time distribution, 4~12 o’clock was the peak time of sudden death, following a slight increasing during 16~20 o’clock, and 0~4 o’clock was the time of lowest incidence. 142 patients had prehospital sudden death, 11 of them received CPR at the first time by witness at the scene, only 5 patients survived after CPR (3.33%, 5/150).Conclusion Emergency treatment of sudden death is usually given priority to middle-aged male-dominated, sudden cardiac death is the main reason. Cardiopulmonary resuscitation of the first responder on the spot combined with professional defibrillation and drug symptomatic treatment can improve the success rate of recovery of sudden death.%目的:分析急诊猝死流行病学特征并探讨心肺复苏对急诊猝死患者的急救效果。方法回顾性分析2012年1月~2015年12月于北京市大兴区人民医急诊科救治的150例急诊猝死病例的临床资料,从猝死患者的性别、年龄、既往史、猝死前先兆症状、诱因、猝死发生场所、猝死发生季节及时间等方面分析猝死的流行病

We have observed doctors who shorten the CPR intervals during resuscitation attempts. During simulation......-based resuscitation training, the recommended 2-min CPR cycles are often deliberately decreased in order to increase the number of scenarios. The aim of this study was to test if keeping 2-min CPR cycles during resuscitation training ensures better adherence to time during resuscitation in a simulated setting......s) or shortened CPR cycles (30-45s instead of 120s) in the scenarios. Adherence to time was measured using the European Resuscitation Council's Cardiac Arrest Simulation Test (CASTest) in retention tests conducted one and 12 weeks after the course. RESULTS: The real-time group adhered significantly...

    Cardiopulmonary resuscitation (CPR) is an intervention used in cases of cardiac arrest to revive patients whose heart has stopped. Because cardiac arrest can have potentially devastating outcomes such as severe neurological deficits even if CPR is performed, patients must be involved in determining in advance if they want CPR in the case of an unexpected arrest. Shared decision making (SDM) facilitates discussions about goals of care regarding CPR in intensive care units (ICUs). Patient decision aids (DAs) are proven to support the implementation of SDM. Many patient DAs about CPR exist, but they are not universally implemented in ICUs in part due to lack of context and cultural adaptation. Adaptation to local context is an important phase of implementing any type of knowledge tool such as patient DAs. User-centered design supported by a wiki platform to perform rapid prototyping has previously been successful in creating knowledge tools adapted to the needs of patients and health professionals (eg, asthma action plans). This project aims to explore how user-centered design and a wiki platform can support the adaptation of an existing DA for CPR to the local context. The primary objective is to use an existing DA about CPR to create a wiki-based DA that is adapted to the context of a single ICU and tailorable to individual patient's risk factors while employing user-centered design. The secondary objective is to document the use of a wiki platform for the adaptation of patient DAs. This study will be conducted in a mixed surgical and medical ICU at Hôtel-Dieu de Lévis, Quebec, Canada. We plan to involve all 5 intensivists and recruit at least 20 alert and oriented patients admitted to the ICU and their family members if available. In the first phase of this study, we will observe 3 weeks of daily interactions between patients, families, intensivists, and other allied health professionals. We will specifically observe 5 dyads of attending intensivists and alert

    the early recognition and delivery of cardiopulmonary resuscitation maneuvers focused on high-quality thoracic compressions and rapid defibrillation by means of the implementation of public access-to-defibrillation programs. These aspects are of the utmost importance and may make the difference on the patient's outcomes, such as on hospital survival with no permanent neurological damage. Early initiation of the Advanced Cardiology Life Support also plays an essential role by keeping the quality of thoracic compressions; adequate airway management; specific treatment for the different arrest rhythms; defibrillation; and assessment and treatment of the possible causes during all the assistance. More recently, emphasis has been given to post-resuscitation care, with the purpose of reducing mortality by means of early recognition and treatment of the post-cardiac arrest syndrome. Therapeutic hypothermia has provided significant improvement of neurological damage and should be performed in comatose individuals post-cardiac arrest. For physicians working in the emergency department or intensive care unit, it is extremely important to improve the treatment given to these patients by means of specific training, thus giving them the chance of higher success and of better survival rates.

    The present study evaluates whether the quality of advanced cardiac life support (ALS) is improved with an interactive prototype assist device. This device consists of an automated external defibrillator linked to a ventilator and provides synchronised visual and acoustic instructions for guidance through the ALS algorithm and assistance for face-mask ventilations. We compared the cardiopulmonary resuscitation (CPR) quality of emergency medical system (EMS) staff members using the study device or standard equipment in a mannequin simulation study with a prospective, controlled, randomised cross-over study design. Main outcome was the effect of the study device compared to the standard equipment and the effect of the number of prior ALS trainings of the EMS staff on the CPR quality. Data were analysed using analyses of covariance (ANCOVA) and binary logistic regression, accounting for the study design. In 106 simulations of 56 two-person rescuer teams, the mean hands-off time was 24.5% with study equipment and 23.5% with standard equipment (Difference 1.0% (95% CI: -0.4 to 2.5%); p = 0.156). With both types of equipment, the hands-off time decreased with an increasing cumulative number of previous CPR trainings (p = 0.042). The study equipment reduced the mean time until administration of adrenaline (epinephrine) by 23 s (p = 0.003) and that of amiodarone by 17 s (p = 0.016). It also increased the mean number of changes in the person doing chest compressions (0.6 per simulation; p trainings, the time intervals in the ALS algorithm until the defibrillations decreased with standard equipment but increased with the study device. EMS staff with limited training in CPR profit from guidance through the ALS algorithm by the study device. However, the study device somehow reduced the ALS quality of well-trained rescuers and thus can only be recommended for ALS provider with limited experience.

    Cardiopulmonary resuscitation (CPR) with the use of mechanical devices is recommended during ambulance transport. However, the CPR quality en route and while in transfer to the emergency department (ED) for out-of-hospital cardiac arrests (OHCAs) remains uncertain. We developed a mechanical CPR device outfitted on a reducible stretcher (M-CPR) and compared with standard manual CPR on a standard stretcher (S-CPR) to evaluate CPR quality. Adult OHCAs transported by five ambulances in a metropolitan area with a population of 3.5 million (many of whom lived in high-rise buildings) from September to October (before-phase) and November to December (after-phase) in 2015 were collected. The reducible stretcher was developed for use in a small elevator during the transfer from scene to ambulance, and the AutoPulse® (ZOLL Medical, Chelmsford, MA, USA) was used for M-CPR. Chest compression fraction (CCF) was measured by transthoracic impedance data using an X-series® cardiac monitor (ZOLL Medical) during time from attachment to patient to arrival to the ED. A comparison of CCF using a Wilcoxon signed-rank test evaluated the difference between the before- and after-phases. Of the eligible 49 OHCAs, 31 (21 in the before-phase and 10 in the after-phase) were analyzed, excluding patients for whom CCF was not measured, for whom M-CPR was not used, who had a return of spontaneous circulation in the field before transport, or who collapsed during transport. There were no differences in demographic data. Median total CCF (median, q1-q3) was significantly higher in the after-phase M-CPR group (85.2, 83.4-86.3) than in the before-phase S-CPR group (80.1, 68.0-85.2) (p = 0.03). Mechanical CPR on the reducible stretcher during the transport of OHCAs to the ED showed a much higher chest compression fraction than standard manual CPR.

    Objective Assessment of outcomes and outcome-related factors of in-hospital cardiopul-monary resuscitation (CPR) based on the " Utstein Style". Methods The study was designed as a prospective, single-institution, registry investigation of 463 patients (included adult and pediatric patients) for whom a CPR was attempted. Results The study population consisted of 320 (69.1 %) male patients and 143 (30. 9%) female patients. The age range of 45- 54, 55- 64, 65- 74 were ranked the first, the second and third highest. In the past medical history, cardiovascular disease and cerebrovascular disorder were two main disorders, accounting for 36. 30% (168/463) and 9. 9% (46/463), respectively. Ventricular fibrillation (VF) was the initial electrocardiographic (ECG) change in 74 patients (16.0%). Two hundred and seventy-three patients received the in-hospital CPR, and 190 patients received the pre-hospital CPR. Spontaneous circulation returned in 34. 6% (160/273) of the in-hospital patients after CPR, and 16. 60% (77/273) survived for 24 hours and 10. 4% (48/273) survived up to the time of discharge. The rates of restoration of spontaneous circulation (ROSC) and survival of the in-hospital CPR were higher than those of the pre-hosptial CPR [47. 6% (130/273) vs. 15. 8% (30/190), 13. 9% (38/273) vs. 5. 3% (10/190), both P<0. 013.

    Since 2005 regular training on cardiopulmonary resuscitation (CPR) has been held long-term.The experienced clinical physicians of the National Mine Emergency Aid Center (Coal General Hospital) are responsible for giving lectures and guiding practical exercises with manikins, based on the American Heart Association Guidelines for CPR and Emergency Cardiac. Care for more than 500 members of more than 60 mine rescue teams from 24 provinces, autonomous regions, and municipalities in China for 5 years. And then similar training at grassroots levels has been held with these persons who are to play a core role. Since 2006 3 sessions of National Mine Rescue Competition were held (2006, 2008, and 2010). The authors of this article participated in 3 Sections on CPR of 3 successive sessions of National Mine Rescue Competition (Sixth to Eighth). The results of the competitions showed that the numbers of general deduct marks in CPR in the Seventh and Eighth Competitions were both less than that in the Sixth Competition (both P<0.05) without significant difference between the results of the latter 2 sessions of competition (P>0.05). The practice showed that since most of the members of the mine rescue teams are from the minors who lack medical knowledge, systematic teaching is necessary, and it is effective to use the experience of one point to lead the whole area.%从2005年开始长期对矿山救护队员进行CPR的培训及训练.根据,国家矿山医疗救护中心(煤炭总医院)经验丰富的临床医师负责讲课,并指导用模拟人实际操作.5年来分批次直接培训全国24个省、市、自治区的重点60余支矿山救护队中核心成员500余名,再通过这些救护队核心成员进行基层的培训及演练.2006年起在全国矿山救援竞赛中进行CPR竞赛,本文作者参与第6~8届CPR竞赛的裁判工作.竞赛结果表明,第七和第八届竞赛中CPR操作扣分均显著低于第六届差异有统计学意义(P0.05).实践表

    Prehospital cardiac arrest is associated with a very poor prognosis. We report a case of complete neurological recovery after prolonged resuscitation involving the use of tenecteplase in a patient with undifferentiated cardiac arrest with a return of spontaneous circulation after 1 hour of resuscitation, where basic life support was commenced immediately by a bystanding family member. Factors associated with an increased chance of survival from out-of-hospital cardiac arrest are discussed as well as the role of thrombolytics in cardiopulmonary resuscitation.

    2002-04-08

    Talking to patients about 'Do Not Attempt Resuscitation' decisions is difficult for many doctors. Communication about 'Do Not Attempt Resuscitation' decisions should occur as part of a wider discussion of treatment goals at an earlier stage in the patient's illness. A doctor should not initiate any treatment, including cardio-pulmonary resuscitation if he/she does not believe it will benefit the patient. An ethical framework is offered which may be of practical help in clarifying decision-making.

    2010-01-01

    Full Text Available Not for resuscitation in India still remains an abstract concept with no clear guidelines or legal frame work. Cardiopulmonary resuscitation is a complex medical intervention which is often used inappropriately in hospitalized patients and usually guided by medical decision making rather than patient-directed choices. Patient autonomy still remains a weak concept and relatives are expected to make this big decision in a short time and at a time of great emotional distress. This article outlines concepts around ethics and medico legal aspects of not for resuscitation, especially in Indian setting.

    Acute poisonings in USA are a leading cause of cardiac arrest, especially in youngsters. Primary survey and cardiopulmonary resuscitation for poisoning is based on ABCDE procedure. One of the most common manifestation of acute poisoning is coma. An open airway should be ensured. Endotracheal intubation should be performed by an experienced person. The mouth-to mouth method of artificial respiration can be applied ultimately. In case of cyanide, hydrogen sulfide, organophosphates and corrosives poisonings a special caution is needed and pocket mask or self-inflating bag with a face mask should be rather used. A quick poison identification and a contact with regional poison information centre regarding patient management are crucial. Different procedures include prolonged cardiopulmonary resuscitation.

    2003-01-01

    To determine the incidence, type, and pattern of injury related to resuscitation attempts in children who die. Retrospective review of ambulance, hospital, and necropsy case records. All children who died aged 0-14 years between 1994 and 1996, and underwent a full necropsy at the Victorian Institute of Forensic Medicine (Melbourne, Australia) were identified. Children who were subject to recognised trauma before resuscitation or died because of a congenital abnormality were excluded. The records of all remaining children were reviewed. Children were grouped according to whether resuscitation was attempted or not. From a total of 346 children who died, 204 (58.6%) were identified as meeting the inclusion criteria. Resuscitation was performed in 153 (75%) children and was started before ambulance arrival in 123 (60.3%) children. Injuries were detected at necropsy in 65 (42.5%) of children who had resuscitation compared with six (11.7%) of children who had no resuscitation (pcauses minor injuries such as superficial bruises and abrasions and the likelihood of such injury increases with the duration of the cardiopulmonary resuscitation. This information should reassure parents and caregivers that basic life support may be instituted without fear of causing significant injury or adversely affecting outcome in the child with cardiorespiratory arrest. Caution must be exercised when attributing significant injuries to resuscitation attempts and alternative causes must be fully investigated.

    Objective To investigate the predictive value of early prognosis of the 40 Hz auditory steady-state response (40 Hz ASSR) in patients with coma following cardiopulmonary resuscitation (CPR). Methods Thirty patients with coma following CPR admitted in the Neurological Intensive Care Unit (NICU) were examined with the 40 Hz ASSR and shortlatency somatosensory evoked potential (SLSEP), and both were graded. Using transferred out of NICU as the short-term outcome end point, the patients with coma following CPR were divided into a survival group (n =21) and a death group (n =9; including brain death). The correlation between the 40 Hz ASSR and SLSEP grading and prognosis was analyzed. Results The grades of the 40 Hz ASSR (r = 0. 722, P = 0.000) or SLSEP (r = 0. 430, P = 0.018) was significantly correlated with the short-term prognosis. The sensitivity, specificity and accuracy of the 40 Hz ASSR for predicting the short-term prognosis were 77. 8%, 100% and 93.3%, respectively; and those of SLSEP were 88. 9%, 61. 9% and 70. 0%, respectively. Conclusions The 40 Hz ASSR has a certain prognostic value in patients with coma following CPR. The higher the grade of the 40 Hz ASSR is, the greater the likelihood of the recent death.%目的 探讨40 Hz听性稳态反应(40 Hz auditory steady-state response,40 Hz ASSR)对心肺复苏(cardiopulmonary resuscitation,CPR)后昏迷患者早期预后的预测价值.方法 对神经重症监护病房(neurological intensive care unit,NICU)收治的30例CPR后昏迷患者进行40 Hz ASSR和短潜伏期体感诱发电位(short-latence somatosensory evoked potentials,SLSEP)检查,并对两者进行分级.以转出NICU时为近期预后评价终点,将CPR后昏迷患者分为存活组(n=21)和死亡组(包括脑死亡,n=9),分析40 Hz ASSR和SLSEP分级与预后的相关性.结果 40 Hz ASSR(r=0.722,P=0.000)和SLSEP(r=0.430,P=0.018)分级与近期预后显著相关.40 Hz ASSR预测近期预后的特异性为100%,敏感性为77.8%,准确性为93

    Objective To investigate the effect of separation of plasma renin activity and aldo⁃sterone on return of spontaneous circulation(ROSC)in patients with cardiopulmonary resuscitation (CPR). Method Thirty patients whose physical examinations were normal were randomly divided into group N; a total of 60 patients with sudden cardiac arrest who were treated with CPR were divided into two groups according to the effect of CPR, 28 patients with restoration of spontaneous circulation were group S, and 32 patients without restoration of spontaneous circulation were group U, at the Guizhou Province People's Hospital from January 2015 to December 2015. Peripheral venous blood of patients with CA 30 minites after CPR was collected, in order to test the plasma renin activity, aldosterone, serum potassium and sodium concentration and to compare each index between different groups. Results ①Compared to group N, plasma renin activity and aldosterone were obviously increased in group S and group U; and plasma renin activity and aldosterone in group U were higher than group S; the difference was statistically significant(P<0.05). ②The proportion of the separation of plasma renin activity and aldosterone in group S was lower than that in group U; the rate of ROSC in the group without separation of aldosterone was higher than the group with separation of aldosterone(2=4.63, P<0.05); and the level of serum potassium concentration in group with separation of aldosterone was higher than that in group with⁃out separation of aldosterone(P<0.01); the level of plasma sodium concentration in group without sepa⁃ration of aldosterone was lower than group with separation of aldosterone(P<0.01). Conclusion The phenomenon of the separation of renin activity and aldosterone exists in the patients who are treated with cardiopulmonary resuscitation, and the separation of plasma renin activity and aldosterone might induce hyponatremia and hyperkalemia, which is the disadvantage of

    For more than a decade, mild induced hypothermia (32 °C-34 °C) has been standard of care for patients remaining comatose after resuscitation from out-of-hospital cardiac arrest with an initial shockable rhythm, and this has been extrapolated to survivors of cardiac arrest with initially nonshockable rhythms and to patients with in-hospital cardiac arrest. Two randomized trials published in 2002 reported a survival and neurological benefit with mild induced hypothermia. One recent randomized trial reported similar outcomes in patients treated with targeted temperature management at either 33 °C or 36 °C. In response to these new data, the International Liaison Committee on Resuscitation Advanced Life Support Task Force performed a systematic review to evaluate 3 key questions: (1) Should mild induced hypothermia (or some form of targeted temperature management) be used in comatose post-cardiac arrest patients? (2) If used, what is the ideal timing of the intervention? (3) If used, what is the ideal duration of the intervention? The task force used Grading of Recommendations Assessment, Development and Evaluation methodology to assess and summarize the evidence and to provide a consensus on science statement and treatment recommendations. The task force recommends targeted temperature management for adults with out-of-hospital cardiac arrest with an initial shockable rhythm at a constant temperature between 32 °C and 36 °C for at least 24 hours. Similar suggestions are made for out-of-hospital cardiac arrest with a nonshockable rhythm and in-hospital cardiac arrest. The task force recommends against prehospital cooling with rapid infusion of large volumes of cold intravenous fluid. Additional and specific recommendations are provided in the document.

    In Mexico, out-of-hospital cardiac arrest is a health problem that represents 33,000 to 150,000 or more deaths per year. The few existent reports show mortality as high as 100% in contrast to some international reports that show higher survival rates. In Queretaro, during the last 5 years there were no successful resuscitation cases. However, in 2012 some patients were reported to have return of spontaneous circulation. We report in this article 3 cases with return of spontaneous circulation and pulse at arrival to the hospital. Two of the patients were discharged alive, one of them with poor cerebral performance category. Community cardiopulmonary resuscitation, early defibrillation and better emergency medical system response times, are related with survival. This poorly explored health problem in Queretaro could be increased with quality and good public education, bystander assisted cardiopulmonary resuscitation, police involvement in cardiopulmonary resuscitation and defibrillation, public access defibrillation programs and measurement of indicators and feedback for better results.

    Background: The history of resuscitation going back thousands of years has been reported in literature throughout history. This concept has undergone several decisive revolutionary changes particularly in pediatrics. Although the cardio-pulmonary resuscitation (CPR) is relatively new in pediatrics, progress has been remarkable in the last a few decades. As it becomes more popular, especially under the influence of globalizing media, CPR also becomes a life requirement that is not restricted t...

  12. Performance of different support surfaces during experimental resuscitation (CPR

    Full Text Available The relationship between the efficacy of resuscitation and the mattresses and backboards used in acute care units, has been studied previously. However, few reports focus on the relative efficacy of resuscitation when using mattresses with different modes of function. This study examines the performance of different support surfaces during experimental cardiopulmonary resuscitation (CPR. The surfaces included a hard surface, a higher specification foam mattress, a dynamic, alternating pressure mattress, and a dynamic, reactive minimum pressure air mattress system. A pressure sensitive mat was placed between the mattresses and each surface and the efficacy of resuscitation measured using differences in compression frequency, compression depth and hands-on time. Our results suggest that the efficacy of resuscitation is dependent on the mode of action of the mattress, while adequate compression frequency and depth do not have a significant effect. In the open system alternating mattress, deflation of the mattress using the CPR function improved the stability of the resuscitation in our study, especially in situations where the height of the air mattress is greater than 20–25 centimeters. Using our experimental system, resuscitation on a closed air system mattress optimally combined stability and effort, while the CPR function converts the air system of the mattress to open, which impairs its functionality during resuscitation. These results indicate that resuscitation is dependent of the mode of action of the mattress and whether the mattress-specific CPR function was used or not. However, the interactions are complex and are dependent on the interaction between the body and the mattress, i.e. its immersion and envelopment properties. Furthermore, this study casts doubt on the necessity of the CPR function in air mattresses.

    Several changes in the way patients with hemorrhagic shock are resuscitated have occurred over the past decades, including permissive hypotension, minimal crystalloid resuscitation, earlier blood transfusion, and higher plasma and platelet-to-red cell ratios. Hemostatic adjuncts, such as tranexamic acid and prothrombin complex, and the use of new methods of assessing coagulopathy are also being incorporated into resuscitation of the bleeding patient. These ideas have been incorporated by many trauma centers into institutional massive transfusion protocols, and adoption of these protocols has resulted in improvements in mortality and morbidity. This article discusses each of these new resuscitation strategies and the evidence supporting their use.

  14. Vascular access in resuscitation: is there a role for the intraosseous route?

    Science.gov (United States)

    Anson, Jonathan A

    2014-04-01

    Intraosseous vascular access is a time-tested procedure which has been incorporated into the 2010 American Heart Association Guidelines for Cardiopulmonary Resuscitation. Intravenous access is often difficult to achieve in shock patients, and central line placement can be time consuming. Intraosseous vascular access, however, can be achieved quickly with minimal disruption of chest compressions. Newer insertion devices are easy to use, making the intraosseous route an attractive alternative for venous access during a resuscitation event. It is critical that anesthesiologists, who are often at the forefront of patient resuscitation, understand how to properly use this potentially life-saving procedure.

    Occasionally, individuals accused of inflicting fatal injuries on infants and young children will claim some variant of the "CPR defense," that is, they attribute the cause of injuries found at autopsy to their "untrained" resuscitative efforts. A 10-year (1994-2003) historical fixed cohort study of all pediatric forensic autopsies at the Miami-Dade County Medical Examiner Department was undertaken. To be eligible for inclusion in the study, children had to have died of atraumatic causes, with or without resuscitative efforts (N(atraumatic) = 546). Of these, 382 had a history of cardiopulmonary resuscitation (CPR; average age of 4.17 years); 248 had CPR provided by trained individuals only; 133 had CPR provided by both trained and untrained individuals; 1 had CPR provided by untrained individuals only. There was no overlap between these 3 distinct groups. Twenty-two findings potentially attributable to CPR were identified in 19:15 cases of orofacial injuries compatible with attempted endotracheal intubation; 4 cases with focal pulmonary parenchymal hemorrhage; 1 case with prominent anterior mediastinal emphysema; and 2 cases with anterior chest abrasions. There were no significant hollow or solid thoracoabdominal organ injuries. There were no rib fractures. The estimated relative risk of injury subsequent to resuscitation was not statistically different between the subset of decedents whose resuscitative attempts were made by trained individuals only, and the subset who received CPR from both trained and untrained individuals. In the single case of CPR application by an untrained individual only, no injuries resulted. The remaining 164 children dying from nontraumatic causes and who did not undergo resuscitative efforts served as a control group; no injuries were identified. This study indicates that in the pediatric population, injuries secondary to resuscitative efforts are infrequent or rare, pathophysiologically inconsequential, and predominantly orofacial in

    The aim of the study was to evaluate the impact of pre-hospital cardio-pulmonary resuscitation, performed by mobile intensive cardiac care units of Magen David Adom (MDA) teams in the framework of a national survey conducted in the period February and March 2000. During the survey, MDA performed 539 resuscitations, 485 of which were performed by mobile intensive care units of MDA, and they constitute the study population of the present analysis. The average age of the patients was 70.5 years, and 68% were men. The mean response time of the mobile intensive care units was 10.3 minutes. In 14% of the cases, a bystander initiated basic cardiac life support before the arrival of the MDA team. Upon arrival of the resuscitation team, 242 patients (50%) had asystole, 19% ventricular tachycardia (VT)/ventricular fibrillation (VF), 13% pulseless electrical activity (PEA), and 18% had other severe arrhythmias. One hundred and ninety-nine patients (41%) were transferred alive to the hospital after successful resuscitation. Hospital summaries were obtained for 148 of these patients. The cause of cardiac arrest was cardiac in 64% of the cases and 48% of the patients who reached the hospital had a previous history of heart disease. Fifty-three patients (11%) were discharged alive from the hospital. Patients discharged alive were younger, more promptly resuscitated, 78% had a cardiac cause of death and 38% of them were in ventricular tachycardia/fibrillation when first seen by the resuscitation team. The rate of successful resuscitation to discharge in the sub-group with VT/VF was 21%, and only 4% for patients in asystole, which is in line with other studies. However, the rate of initiation of resuscitation by bystanders is low in Israel. These data may help the medical staff and the health policy providers in Israel.

    Choking is a common emergency problem. The Heimlich maneuver is unquestionably effective in relieving airway obstruction. Serious and life-threatening complications may arise, however, if the maneuver is applied incorrectly. Two cases of gastric rupture after Heimlich maneuver are reported. Lay public, paramedics and the medical professionals should be educated with the correct technique of Heimlich maneuver and its potential complications. All patients receiving Heimlich maneuver should be examined by an experienced physician.

    To determine whether implementation of Composite Resuscitation Team Training is associated with improvement in survival to discharge and code team performance after pediatric in-hospital cardiopulmonary arrest. We conducted a prospective observational study with historical controls at a 302-bed, quaternary care, academic children's hospital. Inpatients who experienced cardiopulmonary arrest between January 1, 2006, and December 31, 2009, were included in the control group (123 patients experienced 183 cardiopulmonary arrests) and between July 1, 2010, and June 30, 2011, were included in the intervention group (46 patients experienced 65 cardiopulmonary arrests). Code team members were introduced to Composite Resuscitation Team Training and continued training throughout the intervention period (January 1, 2010-June 30, 2011). Training was integrated via in situ code blue simulations (n = 16). Simulations were videotaped and participants were debriefed for education and process improvement. Primary outcome was survival to discharge after cardiopulmonary arrest. Secondary outcome measures were 1) change in neurologic morbidity from admission to discharge, measured by Pediatric Cerebral Performance Category, and 2) code team adherence to resuscitation Standard Operating Performance variables. The intervention group was more likely to survive than the control group (60.9% vs 40.3%) (unadjusted odds ratio, 2.3 [95% CI, 1.15-4.60]) and had no significant change in neurologic morbidity (mean change in Pediatric Cerebral Performance Category 0.11 vs 0.27; p = 0.37). Code teams exposed to Composite Resuscitation Team Training were more likely than control group to adhere to resuscitation Standard Operating Performance (35.9% vs 20.8%) (unadjusted odds ratio, 2.14 [95% CI, 1.15-3.99]). After adjusting for adherence to Standard Operating Performance, survival remained improved in the intervention period (odds ratio, 2.13 [95% CI, 1.06-4.36]). With implementation of Composite

    Full Text Available Non-Hospital Urgent and Emergency Care Units were created to deliver care to patients in chronic or acute situations and to coordinate the flow of urgent care. This descriptive study analyzed the theoretical knowledge of nurses working in these units concerning cardiopulmonary arrest and resuscitation. A questionnaire was applied to 73 nurses from 16 units in seven cities in the region of Campinas, SP, Brazil. The respondents displayed some gaps in their knowledge such as how to detect Cardiopulmonary Arrest (CPA, the ability to list the sequence of basic life support, and how to determine the appropriate compression to ventilation ratio (>60%. They also did not know: the immediate procedures to take after CPA detection (>70%; the rhythm pattern present in a CPA (>80%; and they only partially identified (100% the medication used in cardiopulmonary resuscitation. The average score on a scale from zero to ten was 5.2 (± 1.4.

    Effective resuscitation requires the integration of several cognitive, technical, and behavioral skills. Because resuscitation is performed by teams of health care professionals, these individuals must be able to work together in a coordinated and efficient manner, making teamwork a critical skill for care of patients in distress. Despite the importance of teamwork in health care, little consensus exists as to what it is, how it can most effectively be learned, and how it should be assessed. This article reviews current knowledge on the measurement, training, and importance of teamwork in pediatric resuscitation.

  6. Human factors in resuscitation: Lessons learned from simulator studies

    Full Text Available Medical algorithms, technical skills, and repeated training are the classical cornerstones for successful cardiopulmonary resuscitation (CPR. Increasing evidence suggests that human factors, including team interaction, communication, and leadership, also influence the performance of CPR. Guidelines, however, do not yet include these human factors, partly because of the difficulties of their measurement in real-life cardiac arrest. Recently, clinical studies of cardiac arrest scenarios with high-fidelity video-assisted simulations have provided opportunities to better delineate the influence of human factors on resuscitation team performance. This review focuses on evidence from simulator studies that focus on human factors and their influence on the performance of resuscitation teams. Similar to studies in real patients, simulated cardiac arrest scenarios revealed many unnecessary interruptions of CPR as well as significant delays in defibrillation. These studies also showed that human factors play a major role in these shortcomings and that the medical performance depends on the quality of leadership and team-structuring. Moreover, simulated video-taped medical emergencies revealed that a substantial part of information transfer during communication is erroneous. Understanding the impact of human factors on the performance of a complex medical intervention like resuscitation requires detailed, second-by-second, analysis of factors involving the patient, resuscitative equipment such as the defibrillator, and all team members. Thus, high-fidelity simulator studies provide an important research method in this challenging field.

    Objective To compare the effect of video-based self-instruction (VSI) versus traditional classroom instruction (TCI) on the acquisition and retention of cardiopulmonary resuscitation skills for laypersons. Methods The randomized,controlled clinical trials on CPR instruction for laypersons were collected in the databases such as Cochrane Library, PubMed, and EMBASE. After critical appraisal and analysis of sensitivity and heterogeneity for the involved studies,a meta analysis was conducted to estimate the cumulative effect by RevMan 4.3 software. Results Ten randomized controlled trial (RCT) were involved in the study. Meta analysis showed that there was no significant difference in CPR performance immediately after training by VSI or TCI (OR=l.29,95% confidence interval ranged from 0.44 to 3.75,P>0.05). However,people 40 years old and over in VSI group showed better CPR performance than that of TCI group(OR=4.66,95% confidence interval ranged from 1.12 to 19.32, P0.05). Conclusions Older adults 40 years old and over tend to have better skills acquisition of CPR with VSI than that with TCI. Compared to TCI,VSI is better for short-term but not for long-term retention on CPR skills. It is suggested to further conduct multi-center randomized controlled trials to confirm the effect of VSI on long-term retention of CPR skills.%目的 评价视频自学(VSI)与传统课堂教学(TCI)对公众心肺复苏(CPR)技能获得与保持的效果.方法 采用荟萃分析(meta分析)方法,计算机检索Cochrane图书馆、PubMed、EMBASE等数据库,收集公众CPR培训的随机对照试验,进行文献质量评价后,应用RevMan 4.3软件进行敏感性和异质性分析,计算综合效应.结果 共纳入10篇随机对照试验研究.据meta分析结果显示,VSI组与TCI组CPR技能合格率差异无统计学意义[OR=1.29,95%CI(0.44,3.75),P>0.05].敏感性分析显示,研究对象年龄≥40岁者,VSI组CPR技能合格率明显优于TCI组[OR=4.66,95%CI(1

    ObjectiveTo observe the effects of different doses of Xuebijing on cerebral cortex apoptosis factors bcl-2 and bax in rats at early stage after cardiopulmonary resuscitation (CPR).Methods Thirty-two healthy SD rats aged 12 weeks were divided into four groups by using a random number table method (each,n = 8); all the rats were intubated through the opening of tracheotomy, and the blood pressure was measured through the left/right femoral artery catheter. Asphyxiation was applied to rats, resulting in cardiac arrest (CA), and then cardiopulmonary resuscitation (CPR) was carried out. After restoration of spontaneous circulation (ROSC), 0.9% normal saline 8 mL/kg, 0.9% normal saline 4 mL/kg + Xuebijing 4 mL/kg, 0.9% normal saline 2 mL/kg + Xuebijing 6 mL/kg and Xuebijing 8 mL/kg were given to model group, Xuebijing low dose group, middle dose group and high dose group respectively. The rat body weight, time of CA, CPR-ROSC time, ROSC ratio and the amounts of dopamine and 0.9% saline used in 24 hours were recorded. The positive protein expression levels of bcl-2 and bax in rat cerebral cortex and the ratio of bcl-2/bax was measured at 24 hours after ROSC.Results Compared with the model group, the amount of 0.9% normal saline (mL: 4.2±1.2, 2.6±1.0, 2.5±1.0 vs. 5.5±1.1,P < 0.05) and of dopamine used in 24 hours (μg: 1865±189, 1376±197, 1215±145 vs. 3526±141,P < 0.05), the levels of positive protein expression of bcl-2 (%: 33.4±4.3, 25.5±4.6, 26.1±4.2 vs. 38.5±5.1), and of bax at 24 hours after ROSC (%: 39.5±4.3, 32.8±3.8, 31.9±3.7 vs. 44.3±5.1) and the ratio of bcl-2/bax (0.87±0.16, 0.72±0.13, 0.71±0.14 vs. 0.89±0.11) was significantly decreased in low, middle and high dose groups (allP < 0.05). Compared with the low dose group, the amount of 0.9% normal saline and dopamine used in 24 hours, protein expression levels of bcl-2 and bax at 24 hours and the ratio of bcl-2/bax in middle dose and high dose groups were all lower than those in low dose group

    Objective To assess the feasibility,safety,and effectiveness of early rapid icy normal saline infusion to attain mild hypothermia in cardiac arrest patients. Methods A single-center prospective randomized controlled trial was conducted. From March 2011 to October 2013,patients who had recovery of spontaneous circulation (ROSC)after cardiopulmonary resuscitation (CPR)in Beijing Daxing District People's Hospital were randomly divided into two groups. In icy normal saline group,patients received a rapid infusion of 1 000 mL of 4 ℃ normal saline intravenously to attain a mild hypothermia. In the control group,the patients were treated with ice bag on head,and axillary temperature was monitored. For all patients,rectal temperature was measured and recorded immediately and 1 hour later . The occurrence of pulmonary edema on initial chest X-ray at 6 hours ,occurrence of tremor within 48 hours,ventricular fibrillation recurring within 48 hours,and consciousness or death within 14 days were recorded. Results A total of 45 patients were enrolled,including 23 patients in icy normal saline group and 22 in control group. The patients in icy normal saline group had a rectal temperature descended from(36.7±0.9)℃to(34.9±0.7)℃1 hour later,while the patients in control group had a rectal temperature risen from(36.5±1.0)℃to(37.9±0.9)℃1 hour later. There was significant difference in rectal temperature between two groups (t=2.228,P=0.031). The number of patients who successfully awaken within 14 days in ice normal saline group was significantly larger than that in control group (13 cases vs. 7 cases,χ²=65.710,P=0.021). There was no statistical difference in the occurrence of acute pulmonary edema (4 cases vs . 6 cases),tremor (2 cases vs . 0 case),ventricular fibrillation recurrence (4 cases vs. 5 cases)and death within 14 days (11 cases vs. 12 cases,all P>0.05). Conclusions The study shows that early rapid i.v. infusion of 4℃normal saline is feasible,safe and

    目的 研究大鼠心肺复苏(CPR)后神经细胞线粒体通透性转换孔(MPTP)开放对线粒体呼吸功能的影响,并探讨其可能机制.方法 建立窒息加冰KC1致大鼠心搏骤停(CA)/CPR动物模型,在自主循环恢复(ROSC)后3、6、12、24、48和72 h断头处死大鼠制备大脑皮质内线粒体匀浆.采用分光光度法测定线粒体MPTP的开放程度,用Clark氧电极法分析线粒体呼吸功能,并电镜下观察线粒体超微结构.结果 CA/CPR后大鼠神经细胞线粒体功能明显受损,线粒体呼吸Ⅲ态(R3)速率下降;ROSC后神经细胞MPTP持续处于开放状态,开放程度并不是瞬间增至最大,而是具有时间依赖性.具体表现为:ROSC后6h内神经细胞MPTP开放程度保持低水平,6 h以后开始迅速大量开放,12 h开放程度达到最大,24 h开放程度略有缩小,表明线粒体开始收缩.至48 h开放程度再次加大.72 h又明显缩小,但未达到正常水平(P均<0.05).虽然线粒体R3速率下降.但线粒体呼吸Ⅳ态(R4)速率升高,呼吸控制率(RCR)和磷/氧(P/O)比值明显下降;随着ROSC时间延长,RCR和P/O比值持续在低水平状态(P<0.05或P<0.01).透射电镜下观察细胞有明显损伤.相关分析表明,MPTP开放与RCR呈明显正相关(r=0.025,P<0.05).结论 CPR后MPTP开放是加重神经细胞能量代谢障碍的主要原因,在ROSC后早期即12 h以内如能及时应用抑制MPTP开放的策略,可能会使神经细胞的线粒体功能朝着良性方向发展.为神经功能的恢复赢得机会.%Objective To investigate the effect of opening of neuronal mitochondrial permeability transition pore (MPTP) on respiratory function after cardiopulmonary resuscitation (CPR) in rats and its possible mechanism.Methods Cardiac arrest (CA)/CPR rat model was reproduced by asphyxiation and ice-cold KCI followed resuscitation and restoration of spontaneous circulation (ROSC).

    Objective To assess the effects of hypothermia induced by 4 ℃ normal saline (NS) on biochemical function, enzymology and morphology of liver in swine after the success of cardiopulmonary resuscitation (CPR) for cardiac arrest(CA). Method The swine were resuscitated with standard CPR 4 minutes after ventricular fibrillation(VF) ,and the survived swine were randomly(random number) divided into two groups. In hypothermia(LT) group (n = 5), swine were treated with continuous infusion of 4 ℃ NS at the speed of 1.33 mL/(kg·min) for 22 min, and then slow the speed to 10 mL/(kg·h) for 4 h. In normothermia (NT) group ( n= 5) swine were treated with the infusion of NS with room temperature instead of cryogenic NS at the same speed as the LT group. The hemodynamics and the changes of blood gas were monitored until 4 h after restoration of spontaneous circulation (ROSC), and blood samples were taken to detect serum alanine aminotransferase (ALT), aspartate aminotransferase (AST) and lactate dehydrogenase (LDH) before VF and 10 min, 2 h and 4 h after ROSC. All swine were sacrificed 24 hours after ROSC, and their liver tissues were taken away for detecting Na+ -K + -ATP enzyme and Ca2+ -ATP enzyme as well as the histological changes under both light and electron microscopy. Results The heart rate, MAP, cardiac output(CO) and coronary perfusion pressure(CPP) of swine were stable in LT group ( P > 0.05). The AST, ALT and LDH increased in both groups but less in LT group. The hepatic ATP enzyme activity was much higher in LT group ( P < 0.05). Compared with the NT group, there were less cellularedema,necrosis or inflammatory cells infiltration, and better morphosis of mitochondria of livers found in swine of LT group. Conclusions The continuous administration of 4 ℃ NS after ROSC could quickly lower the core body temperature, and it could keep hemodynamics and oxygen metabolisms stable, protecting the biochemical function,enzymology and morphology of liver in swine

    A 4-month-old boy presented with cardiopulmonary arrest on arrival after a brief period of lethargy. Laboratory examination indicated severe hyperkalemia, hyponatremia, metabolic acidosis, and slightly elevated C-reactive protein. Whole body computed tomography identified left-dominant hydronephrosis, hydroureter and cholelithiasis. Despite cardiac arrest >30 min, he was successfully resuscitated and treated with therapeutic hypothermia. Escherichia coli was detected on urine culture. Renal ultrasound showed bilateral hydronephrosis, grade II in the right and grade IV in the left. Retrospective analysis of the blood sample at admission indicated a high level of aldosterone. The patient recovered almost fully with no electrolyte imbalance and normal plasma renin and aldosterone, leading to the diagnosis of secondary pseudohypoaldosteronism associated with bilateral infected hydronephrosis. In this case, cholelithiasis, which may account for chronic dehydration, was a diagnostic clue in the absence of information of pre-existing situations. © 2014 The Authors.

    Children who require cardiopulmonary resuscitation present high mortality and morbidity. The few studies that have been published on this subject use different terminology and methodology in data collection, which makes comparisons, evaluation of efficacy, and the performance of meta-analyses, etc. difficult. Consequently, standardized data collection both in clinical studies on cardiorespiratory arrest and in cardiopulmonary resuscitation in the pediatric age group are required. The Spanish Group of Pediatric Cardiopulmonary Resuscitation emphasizes that recommendations must be simple and easy to understand. The first step in the elaboration of guidelines on data collection is to develop uniform definitions (glossary of terms). The second step comprises the so-called time intervals that include time periods between two events. To describe the intervals of cardiorespiratory arrest different clocks are used: the patient's watch, that of the ambulance, the interval between call and response, etc.Thirdly, a series of clinical results are gathered to determine whether the efforts of cardiopulmonary resuscitation have a positive effect on the patient, the patient's family and society. With the information gathered a registry of data that includes the patient's personal details, general data of the cardiopulmonary resuscitation, treatment, times of performance and definitive patient outcome is made.

    PURPOSE OF REVIEW: To discuss the recent developments in and evolvement of next generation haemostatic resuscitation in bleeding trauma. RECENT FINDINGS: Mortality from major trauma is a worldwide problem, and massive haemorrhage remains a major cause of potentially preventable deaths. Development...... of coagulopathy further increases trauma mortality emphasizing that coagulopathy is a key target in the phase of bleeding. The pathophysiology of coagulopathy in trauma reflects at least three distinct mechanisms that may be present isolated or coexist: acute traumatic coagulopathy, coagulopathy associated...... with the lethal triad, and consumptive coagulopathy. The concepts of 'damage control surgery' and 'damage control resuscitation' have been developed to ensure early control of bleeding and coagulopathy to improve outcome in bleeding trauma. Haemostatic resuscitation aims at controlling coagulopathy and consists...

  1. A primer on burn resuscitation

    Full Text Available Since the early 1900s, the scope of burn resuscitation has evolved dramatically. Due to various advances in pre-hospital care and training, under-resuscitation of patients with severe burns is now relatively uncommon. Over-resuscitation, otherwise known as "fluid creep", has emerged as one of the most important problems during the initial phases of burn care over the past decade. To avoid the complications of over-resuscitation, careful hourly titration of fluid rates based on compilation of various clinical end points by a bedside provider is vital. The aim of this review is to provide a practical approach to the resuscitation of severely burned patients.

    Vasoplegia syndrome, characterized by hypotension refractory to fluid resuscitation or high-dose vasopressors, low systemic vascular resistance, and normal-to-increased cardiac index, is associated with increased morbidity and mortality after cardiothoracic surgery. Methylene blue inhibits inducible nitric oxide synthase and guanylyl cyclase, and has been used to treat vasoplegia during cardiopulmonary bypass. However, because methylene blue is associated with increased pulmonary vascular resistance, its use in patients undergoing lung transplantion has been limited. Herein, we report the use of methylene blue to treat refractory vasoplegia during cardiopulmonary bypass in a patient undergoing double-lung transplantation.

    Objective To observe the expression changes in apoptosis-related microRNA(miRNA) in cerebral cortex after cardiac arrest-cardiopulmonary resuscitation(CA-CPR)in rats and explore the factors that may affect the mechanism of CPR. Methods 24 clean male Sprague-Dawley(SD)rats were randomly divided into three groups,the normal control group,sham operation group and CA-CPR group(each n=8). The animal model of CA induced by asphyxia was established and CPR was performed. In the normal control group,no special management was performed. In the sham operation group,only abdominal cavity anesthesia,tracheotomy,vascular puncture and electrocardiogram(ECG)were performed without clamping the trachea and resuscitating. Normal feeding in normal control group and 24 hours after tracheotomy in sham operation group,at 24 hours after recovery of spontaneous circulation(ROSC)in CA-CPR group,cerebral cortex specimens were obtained for detection of the expression of miRNA by using real time fluorescence quantitative reverse transcription - polymerase chain reaction(RT-PCR).

    Full Text Available Appropriate fluid replacement is an essential component of trauma fluid resuscitation. Once hemorrhage is controlled, restoration of normovolemia is a priority. In the presence of uncontrolled haemorrhage, aggressive fluid management may be harmful. The crystalloid-colloid debate continues but existing clinical practice is more likely to reflect local biases rather than evidence based medicine. Colloids vary substantially in their pharmacology and pharmacokinetics,and the experimental finding based on one colloid cannot be extrapolated reliably to another. In the initial stages of trauma resuscitation the precise fluid used is probably not important as long as an appropriate volume is given. Later, when the microcirculation is ′leaky′, there may be some advantages to high or medium weight colloids such as hydroxyethyl starch. Hypertonic saline solutions may have some benefit in patients with head injuries. A number of hemoglobin solutions are under development, but one of the most promising of these has been withdrawn recently. It is highly likely that at least one of these solutions will eventually become routine therapy for trauma patient resuscitation. In the meantime, contrary to traditional teaching, recent data suggest that restrictive strategy of red cell transfusion may improve outcome in some critically ill patients.

  13. Colloids in Acute Burn Resuscitation.

    Colloids have been used in varying capacities throughout the history of formula-based burn resuscitation. There is sound experimental evidence that demonstrates colloids' ability to improve intravascular colloid osmotic pressure, expand intravascular volume, reduce resuscitation requirements, and limit edema in unburned tissue following a major burn. Fresh frozen plasma appears to be a useful and effective immediate burn resuscitation fluid but its benefits must be weighed against its costs, and risks of viral transmission and acute lung injury. Albumin, in contrast, is less expensive and safer and has demonstrated ability to reduce resuscitation requirements and possibly limit edema-related morbidity. Copyright © 2016 Elsevier Inc.

    Cardiopulmonary resuscitation (CPR) during flight is challenging and has to be sustained for long periods. In this setting a mechanical-resuscitation-device (MRD) might improve performance. In this study we compared the quality of resuscitation of trained flight attendants practicing either standard basic life support (BLS) or using a MRD in a cabin-simulator. Prospective, open, randomized and crossover simulation study. Study participants, competent in standard BLS were trained to use the MRD to deliver both chest compressions and ventilation. 39 teams of two rescuers resuscitated a manikin for 12 min in random order, standard BLS or mechanically assisted resuscitation. Primary outcome was "absolute hands-off time" (sum of all periods during which no hand was placed on the chest minus ventilation time). Various parameters describing the quality of chest compression and ventilation were analysed as secondary outcome parameters. Use of the MRD led to significantly less "absolute hands-off time" (164±33 s vs. 205±42 s, p<0.001). The quality of chest compression was comparable among groups, except for a higher compression rate in the standard BLS group (123±14 min(-1) vs. 95±11 min(-1), p<0.001). Tidal volume was higher in the standard BLS group (0.48±0.14 l vs. 0.34±0.13 l, p<0.001), but we registered fewer gastric inflations in the MRD group (0.4±0.3% vs. 16.6±16.9%, p<0.001). Using the MRD resulted in significantly less "absolute hands-off time", but less effective ventilation. The translation of higher chest compression rate into better outcome, as shown in other studies previously, has to be investigated in another human outcome study.

    2012-01-01

    Full Text Available Introduction. The incidence of sudden cardiac death in patients with severe symptomatic aortic stenosis is up to 34% and resuscitation is described as highly unsuccessful. Case report. A 72-year-old female patient with severe aortic stenosis combined with severe mitral regurgitation and three-vessel coronary artery disease was successfully resuscitated following two in-hospital cardiac arrests. The first cardiac arrest occurred immediately after intraarterial injection of low osmolar iodinated agent during coronary angiography. Angiography revealed 90% occlusion of the proximal left main coronary artery and circumflex branch. The second arrest followed induction of anesthesia. Following successful open-chest resuscitation, aortic valve replacement, mitral valvuloplasty and three-vessel aortocoronary bypass were performed. Postoperative pericardial tamponade required surgical revision. The patient recovered completely. Conclusion. Decision to start resuscitation may be justified in selected patients with critical aortic stenosis, even though cardiopulmonary resuscitation in such cases is generally considered futile.

    Survival after traumatic cardiopulmonary arrest (TCPA) is rare and requires significant resource expenditure. Organ donation as an outcome of TCPA resuscitation has not yet been included in a cost analysis. The aims of this study were to identify variables associated with survival and organ donation after TCPA, and to estimate the cost of achieving these outcomes. We hypothesized that the inclusion of organ donation as a potential outcome would make TCPA resuscitation more cost-effective. Adult patients who required resuscitation for TCPA at a level I trauma center were retrospectively reviewed over 36 months. Data were obtained from medical records, hospital accounting records, and the local organ procurement agency. Outcomes included survival to discharge, neurologic function, and organ donor eligibility. An individual-level state-transition cost-effectiveness model was used to evaluate the cost of TCPA resuscitation with and without organ donation included as an outcome. Incremental cost-effectiveness ratio was calculated to determine additional cost per life saved when organ donation is included. Over the study period, 8,932 subjects were evaluated. Traumatic cardiopulmonary arrest occurred in 237 patients (3%). The mortality rate was 97%. Variables associated with survival included emergency department disposition to the operating room (p organ donation with a procurement rate of 2%. Organ donor eligibility was associated with arrest after arrival to the emergency department (p donation was $538,000. The incremental cost-effectiveness ratio was $76,816 per additional life saved including donation as an outcome. The decision to pursue resuscitation should continue to be based on the presence of signs of life, especially pupil reactivity and duration of arrest. If the primary objective is survival, organ procurement will be maximized without conflict of interest. Early fresh frozen plasma transfusion may increase successful organ donation.

    Full Text Available Cardiac surgery carried out on cardiopulmonary bypass (CPB in a pregnant woman is associated with poor neonatal outcomes although maternal outcomes are similar to cardiac surgery in non-pregnant women. Most adverse maternal and fetal outcomes from cardiac surgery during pregnancy are attributed to effects of CPB. The CPB is associated with utero-placental hypoperfusion due to a number of factors, which may translate into low fetal cardiac output, hypoxia and even death. Better maternal and fetal outcomes may be achieved by early pre-operative optimization of maternal cardiovascular status, use of perioperative fetal monitoring, optimization of CPB, delivery of a viable fetus before the operation and scheduling cardiac surgery on an elective basis during the second trimester.

In this review, we will present the current evidence for the use of HES solutions including data from recent high-quality randomized clinical trials. RECENT FINDINGS: Meta-analyses of HES vs. control fluids show clear...... and surgical patients cannot adequately assess safety issues and do not show clear benefit with the use of HES. There is currently no firm evidence that tetrastarch has better safety profile than the former HES solutions. SUMMARY: There is no evidence for an overall beneficial effect of HES in any subgroup...... of critically ill patients, but there are clear signs of harm. As safer alternatives exist, we recommend that HES is no longer used in critically ill patients....

    The quality of education, CPR guidelines and the chain of survival all contribute to patient outcome following cardiac arrest. Increasing concerns about patient safety have focused attention on the methods used to train and prepare doctors for clinical practice. Reductions in clinical exposure at both undergraduate and postgraduate level have been implicated in junior doctors inability to recognise and manage critically ill patients. Simulation is used as a central training tool in contemporary advanced life support teaching. Simulation provides a learning opportunity for controlled clinical practice without putting patients or others at risk. This review examines the history and rationale for simulation training in resuscitation and provides some background to the learning theories that underpin it. The role of task trainers, high and low fidelity patient simulators and computer assisted simulation as teaching tools are discussed.

    Intensive cardiopulmonary management is frequently undertaken in patients with spinal cord injury (SCI), particularly due to the occurrence of neurogenic shock and ventilatory insufficiency and in an attempt to reduce secondary injury. We undertook a systematic review of the literature to examine the evidence that intensive care management improves outcome after SCI and to attempt to define key parameters for cardiopulmonary support/resuscitation. We review the literature in five areas: management of SCI patients in specialized centers, risk in SCI patients of cardiopulmonary complications, parameters for blood pressure and oxygenation/ventilation support following SCI, risk factors for cardiopulmonary insufficiency requiring ICU care after SCI, and preventative strategies to reduce the risks of cardiopulmonary complications in SCI patients. The literature supports that, in light of the significant incidence of cardiorespiratory complications, SCI patients should be managed in a monitored special care unit. There is weak evidence supporting the maintenance of MAP >85 mmHg for a period extending up to 1 week following SCI.

While attending a heart arrest patient, it is crucial that the use of external semi-automated defibrillator (AED is included in the training. The purpose of the present study is to compare Psychomotor Ability and the Theoretical Knowledge of lay people on cardiopulmonary resuscitation (CPR using AED, before and after training. This sample was composed of 40 administrative workers of a public institution that were trained on CPR technique using EAD, as an experiment. The significantly higher scores in the assessment instrument items of Psychomotor Ability and Theoretical Knowledge, after training, indicates that the participants have presented improvements in their performances.

  9. The impact of response time reliability on CPR incidence and resuscitation success: a benchmark study from the German Resuscitation Registry

    Science.gov (United States)

    2011-01-01

    Introduction Sudden cardiac arrest is one of the most frequent causes of death in the world. In highly qualified emergency medical service (EMS) systems, including well-trained emergency physicians, spontaneous circulation may be restored in up to 53% of patients at least until admission to hospital. Compared with these highly qualified EMS systems, markedly lower success rates are observed in other systems. These data clearly show that there are considerable differences between EMS systems concerning treatment success following cardiac arrest and resuscitation, although in all systems international guidelines for resuscitation are used. In this study, we investigated the impact of response time reliability (RTR) on cardiopulmonary resuscitation (CPR) incidence and resuscitation success by using the return of spontaneous circulation (ROSC) after cardiac arrest (RACA) scores and data from seven German EMS systems participating in the German Resuscitation Registry. Methods Anonymised patient data after out-of-hospital cardiac arrest gathered from seven EMS systems in Germany from 2006 to 2009 were analysed with regard to socioeconomic factors (population, area and EMS unit-hours), process quality (RTR, CPR incidence, special CPR measures and prehospital cooling), patient factors (age, gender, cause of cardiac arrest and bystander CPR). End points were defined as ROSC, admission to hospital, 24-hour survival and hospital discharge rate. χ2 tests, odds ratios and the Bonferroni correction were used for statistical analyses. Results Our present study comprised 2,330 prehospital CPR patients at seven centres. The incidence of sudden cardiac arrest ranged from 36.0 to 65.1/100,000 inhabitants/year. We identified two EMS systems (RTR 70%) reached patients within 8 minutes of the call to the dispatch centre 70.4% up to 95.5% of the time. EMS systems arriving relatively later at the patients side (RTR CPR less frequently and admit fewer patients alive to hospital

    Background: Cardiac operations in pregnant patients are a challenge for physicians in multidisciplinary teams due to the complexity of the condition which affects both mother and baby. Management strategies vary on a case-by-case basis. Feto-neonatal and maternal outcomes after cardiopulmonary bypass (CPB) in pregnancy, especially long-term follow-up results, have not been sufficiently described. Methods: This review was based on a complete literature retrieval of articles published between 1991 and April 30, 2013. Results: Indications for CPB during pregnancy were cardiac surgery in 150 (96.8 %) patients, most of which consisted of valve replacements for mitral and/or aortic valve disorders, resuscitation due to amniotic fluid embolism, autotransfusion, and circulatory support during cesarean section to improve patient survival in 5 (3.2 %) patients. During CPB, fetuses showed either a brief heart rate drop with natural recovery after surgery or, in most cases, fetal heart rate remained normal throughout the whole course of CPB. Overall feto-neonatal mortality was 18.6 %. In comparison with pregnant patients whose baby survived, feto-neonatal death occurred after a significantly shorter gestational period at the time of onset of cardiac symptoms, cardiac surgery/resuscitation under CPB in the whole patient setting, or cardiac surgery/resuscitation with CPB prior to delivery. Conclusions: The most common surgical indications for CPB during pregnancy were cardiac surgery, followed by resuscitation for cardiopulmonary collapse. CPB was used most frequently in maternal cardiac surgery/resuscitation in the second trimester. Improved CPB conditions including high flow, high pressure and normothermia or mild hypothermia during pregnancy have benefited maternal and feto-neonatal outcomes. A shorter gestational period and the use of CPB during pregnancy were closely associated with feto-neonatal mortality. It is therefore important to attempt delivery ahead of

    Cardiac arrest induces whole-body ischemia, which causes damage to multiple organs. Understanding how each organ responds to ischemia/reperfusion is important to develop better resuscitation strategies. Because direct measurement of organ function is not practicable in most animal models, we attempt to use mitochondrial respiration to test efficacy of resuscitation on the brain, heart, kidney, and liver following prolonged cardiac arrest. Male Sprague-Dawley rats are subjected to asphyxia-induced cardiac arrest for 30 min or 45 min, or 30 min cardiac arrest followed by 60 min cardiopulmonary bypass resuscitation. Mitochondria are isolated from brain, heart, kidney, and liver tissues and examined for respiration activity. Following cardiac arrest, a time-dependent decrease in state-3 respiration is observed in mitochondria from all four tissues. Following 60 min resuscitation, the respiration activity of brain mitochondria varies greatly in different animals. The activity after resuscitation remains the same in heart mitochondria and significantly increases in kidney and liver mitochondria. The result shows that inhibition of state-3 respiration is a good marker to evaluate the efficacy of resuscitation for each organ. The resulting state-3 respiration of brain and heart mitochondria following resuscitation reenforces the need for developing better strategies to resuscitate these critical organs following prolonged cardiac arrest.

    Full Text Available Background Early recognition of the signs and symptoms of clinical deterioration could diminish the incidence of cardiopulmonary arrest. The present study investigates outcomes with respect to cardiopulmonary arrest rates in institutions with and without rapid response systems (RRSs and the current level of cardiopulmonary arrest rate in tertiary hospitals. Methods This was a retrospective study based on data from 14 tertiary hospitals. Cardiopulmonary resuscitation (CPR rate reports were obtained from each hospital to include the number of cardiopulmonary arrest events in adult patients in the general ward, the annual adult admission statistics, and the structure of the RRS if present. Results Hospitals with RRSs showed a statistically significant reduction of the CPR rate between 2013 and 2015 (odds ratio [OR], 0.731; 95% confidence interval [CI], 0.577 to 0.927; P = 0.009. Nevertheless, CPR rates of 2013 and 2015 did not change in hospitals without RRS (OR, 0.988; 95% CI, 0.868 to 1.124; P = 0.854. National university-affiliated hospitals showed less cardiopulmonary arrest rate than private university-affiliated in 2015 (1.92 vs. 2.40; OR, 0.800; 95% CI, 0.702 to 0.912; P = 0.001. High-volume hospitals showed lower cardiopulmonary arrest rates compared with medium-volume hospitals in 2013 (1.76 vs. 2.63; OR, 0.667; 95% CI, 0.577 to 0.772; P < 0.001 and in 2015 (1.55 vs. 3.20; OR, 0.485; 95% CI, 0.428 to 0.550; P < 0.001. Conclusions RRSs may be a feasible option to reduce the CPR rate. The discrepancy in cardiopulmonary arrest rates suggests further research should include a nationwide survey to tease out factors involved in in-hospital cardiopulmonary arrest and differences in outcomes based on hospital characteristics.

    Nurses in the hospital setting must be knowledgeable about resuscitation procedures and proficient in the delivery of care during an emergency. They must be ready to implement their knowledge and skills at a moment's notice. A common dilemma for many nurses is that cardiopulmonary emergencies (Code Blues) are infrequent occurrences. Therefore, how do nurses remain competent and confident in their implementation of emergency skills while having limited exposure to the equipment and minimal experience in emergency situations? A team of nurse educators at a regional medical center in Washington State applied adult learning theory and accelerated learning techniques to develop and present a series of learning activities to enhance the staff's familiarity with emergency equipment and procedures. The series began with a carnival venue that provided hands-on practice and review of emergency skills and was reinforced with subsequent random unannounced code drills led by both educators and charge nurses.

    To describe the involvement and input of physicians and nurses in cardiopulmonary resuscitation (CPR / do not attempt resuscitation (DNAR) decisions; to analyse decision patterns; and understand the practical implications. A Qualitative Grounded Theory study using one-time open-ended interviews with 40 volunteer physicians and 52 nurses drawn from acute care wards with mixes of heterogeneous cases in seven different hospitals in German-speaking Switzerland. Establishing DNAR orders in the best interests of patients was described as a challenging task requiring the leadership of senior physicians and nurses. Implicit decisions in favour of CPR predominated at the beginning of hospitalisation; depending on the context, they were relieved/superseded by explicit DNAR decisions. Explicit decisions were the result of hierarchical medical expertise, of multilateral interdisciplinary expertise, of patient autonomy and/or of negotiated patient autonomy. Each type of decision, implicit or explicit, potentially represented a team consensus. Non-consensual decisions were prone to precipitate personal or team conflicts, and, occasionally, led to non-compliance. Establishing DNAR orders is a demanding task. Reaching a consensus is of crucial importance in guaranteeing teamwork and good patient care. Communication and negotiation skills, professional and personal life experience and empathy for patients and colleagues are pivotal. Therefore, leadership by experienced senior physicians and nurses is needed and great efforts should be made with regard to multidisciplinary education.

    Leadership skills directly correlate with the quality of technical performance of cardiopulmonary resuscitation (CPR) and clinical outcomes. Despite an improved focus on non-technical skills in CPR training, the leadership of cardiac arrests is often variable. To assess the perceptions of leadership and team working among members of a cardiac arrest team and to evaluate future training needs. Cross-sectional survey of 102 members of a cardiac arrest team at an Acute Hospital Trust in the UK with 892 inpatient beds. Responses sought from doctors, nurses and healthcare assistants to 12 rated statements and 4 dichotomous questions. Of 102 responses, 81 (79%) were from doctors and 21 (21%) from nurses. Among specialist registrars 90% agreed or strongly agreed that there was clear leadership at all arrests compared with between 28% and 49% of nurses and junior doctors respectively. Routine omission of key leadership tasks was reported by as many as 80% of junior doctors and 50% of nurses. Almost half of respondents reported non-adherence with Advanced Life Support (ALS) guidelines. Among junior members of the team, 36% felt confident to lead an arrest and 75% would welcome further dedicated cardiac arrest leadership training. Leadership training is integrated into the ALS (Resus Council, UK) qualification. However, this paper found that in spite of this training; standards of leadership are variable. The findings suggest a pressing need for further dedicated cardiac arrest leadership training with a focus on improving key leadership tasks such as role assignment, team briefing and debriefing.

    In three cases of cardiac arrest in which resuscitation was successful, there were striking similarities. The patients were men with anterior myocardial infarction and the mode of cardiac arrest was ventricular fibrillation. Corrective action was begun promptly after arrest occurred. In each case vasopressor agents were required for three to five days after resuscitation before the cardiovascular system was able to maintain a normal blood pressure without this aid. Convalescence was satisfactory and each patient returned to his usual occupation. The procedure that was used for cardiac resuscitation was based on artifical respiration (by any of several methods) and artificial circulation by external cardiac compression to provide a flow of oxygenated blood to the brain. Once this is established, time is afforded to determine what other steps are needed.

    Mitochondrial dysfunction plays a critical role in brain injury after cardiac arrest and cardiopulmonary resuscitation (CPR). Recent studies demonstrated that hydrogen sulfide (H2S) donor compounds preserve mitochondrial morphology and function during ischemia-reperfusion injury. In this study, we sought to explore the effects of sodium hydrosulfide (NaHS) on brain mitochondria 24h after cardiac arrest and resuscitation. Male Sprague-Dawley rats were subjected to 6min cardiac arrest and then resuscitated successfully. Rats received NaHS (0.5mg/kg) or vehicle (0.9% NaCl, 1.67ml/kg) 1min before the start of CPR intravenously, followed by a continuous infusion of NaHS (1.5mg/kg/h) or vehicle (5ml/kg/h) for 3h. Neurological deficit was evaluated 24h after resuscitation and then cortex was collected for assessments. As a result, we found that rats treated with NaHS revealed an improved neurological outcome and cortex mitochondrial morphology 24h after resuscitation. We also observed that NaHS therapy reduced intracellular reactive oxygen species generation and calcium overload, inhibited mitochondrial permeability transition pores, preserved mitochondrial membrane potential, elevated ATP level and ameliorated the cytochrome c abnormal distribution. Further studies indicated that NaHS administration increased mitochondrial biogenesis in cortex at the same time. Our findings suggested that administration of NaHS 1min prior CPR and followed by a continuous infusion ameliorated neurological dysfunction 24h after resuscitation, possibly through mitochondria preservation as well as by promoting mitochondrial biogenesis.

    Full Text Available Objective To observe the effects of four cardiopulmonary resuscitation (CPR methods on lung ventilation of pigs with respiratory arrest. The four CPR methods included chest compression CPR (C-CPR, compression under the diaphragm CPR (D-CPR, abdominal compression CPR (A-CPR, and abdominal wall lifting and compression CPR (L-CPR. Methods  A total of 28 healthy domestic pigs were randomly divided into four groups. The pig respiratory arrest model was reproduced by intravenous injection of suxamethonium. Instantly after respiratory arrest, one of the 4 CPR methods was performed immediately on the groups of pigs respectively. After 2min of CPR, compression was stopped. The experimental pigs were given assisted respiration using a ventilator until autonomous respiration recovered. The tidal volume (VT in basic status and that during resuscitation by the four respective resuscitation methods was determined, and minute ventilation (MV was calculated. Furthermore, heart rate (HR, mean arterial blood pressure, and recovery time of autonomous respiration were compared between all the groups. Results In basic status, there was no statistical difference (P > 0.05 in VT and MV between the four groups. Approximately 2min after resuscitation, the VT and MV of D-CPR were higher than that of C-CPR; that of A-CPR was higher than that of D-CPR; and that of L-CPR was higher than that of A-CPR. The differences were statistically significant (P 0.05. HR in C-CPR and D-CPR were notably lower than the basic value (P < 0.01. Two minutes after resuscitation, mechanical ventilation was given, and HR in all the groups was close to the basic value 5 min after resuscitation. In the respiratory arrest pig model, L-CPR could provide more effective VT and MV than the other methods. Conclusion For the porcine respiratory arrest model, L-CPR can provide more effective lung ventilation than the other methods.

Materials and Methods: Retrospective hospital-based study. Independent case reviewers using a questionnaire designed to study NFR documentation reviewed documentation of NFR in 88 case records. Results: Prognosis was documented in only 40% of cases and palliative care was offered to two-third of patients with documented NFR. There was no documentation of the cardiopulmonary resuscitation (CPR process or outcomes of CPR in most of the cases. Only in less than 50% of cases studied there was documented evidence to suggest that the reason for NFR documentation was consistent with patient′s choices. Conclusion: Good discussion, unambiguous documentation and clinical supervision of NFR order ensure dignified and quality care to the dying.

    Cardiopulmonary resuscitation (CPR) is relatively novel branch of medical science, however first descriptions of mouth-to-mouth ventilation are to be found in the Bible and literature is full of descriptions of different resuscitation methods - from flagellation and ventilation with bellows through hanging the victims upside down and compressing the chest in order to stimulate ventilation to rectal fumigation with tobacco smoke. The modern history of CPR starts with Kouwenhoven et al. who in 1960 published a paper regarding heart massage through chest compressions. Shortly after that in 1961Peter Safar presented a paradigm promoting opening the airway, performing rescue breaths and chest compressions. First CPR guidelines were published in 1966. Since that time guidelines were modified and improved numerously by two leading world expert organizations ERC (European Resuscitation Council) and AHA (American Heart Association) and published in a new version every 5 years. Currently 2010 guidelines should be obliged. In this paper authors made an attempt to present history of development of resuscitation techniques and methods and assess the influence of previous lifesaving methods on nowadays technologies, equipment and guidelines which allow to help those women and men whose life is in danger due to sudden cardiac arrest.

    Full Text Available Carbon dioxide (CO2 embolism is a rare but potentially fatal complication of laparoscopic surgery. We report a case of presumed CO2 embolism in a 35-year-old female during laparoscopic ureteric reconstructive surgery. After 2 h of operating time, a sudden decrease in end-tidal carbon dioxide and deterioration of hemodynamic status followed by cardiac arrest with pulseless electrical activity suggested gas embolism. Immediate cardiopulmonary resuscitation and inotropic support resulted in successful outcome. Thus, early recognition of the complication and prompt treatment can avoid catastrophy.

    Full Text Available Doctors and nurses working in hospital emergency departments face ethical and moral conflicts more so than in other health care units. Traditional curricular approaches to health professional education have been embedded in a discriminatory societal context and as such have not prepared health professionals adequately for the ethical realities of their practice. Furthermore, the discourse on ethical theories and ethical principles do not provide clear-cut solutions to ethical dilemmas but rather serve as a guide to ethical decision- making. Within the arena of trauma and resuscitation, fundamental ethical principles such as respect for autonomy, beneficence, non-maleficence and justice cannot be taken as absolutes as these may in themselves create moral conflict. Resuscitation room activities require a balance between what is “ ethically" correct and what is “pragmatically required” . Because of the urgent nature of a resuscitation event, this balance is often under threat, with resultant transgression of patients’ rights. This article explores the sources of ethical and moral issues in trauma care and proposes a culture of human rights to provide a context for preserving and protecting trauma patients’ rights during resuscitation. Recommendations for education and research are alluded to in concluding the article.

    The authors have developed an ECPB system, which can be applied quickly, safely and easily under an emergency condition requiring cardiac massage and artificial ventilation. Fundamentally, the ECPB system consists of 3 parts; a portable ECPB apparatus, a pair of percutaneous cannulae and a short circuit connecting an oxygenator with the cannulae. The ECPB apparatus is assembled with commercially available components (i.e., a centrifugal pump, a battery pack, a temperature controller, a compact membrane oxygenator with a heat exchanger, etc) and they are placed on a mobile cart. The circuit is primed with 300 ml of lactated Ringer solution. The priming can be done within 15 minutes via a reservoir. It is also possible to keep the primed circuit to be ready for emergency use at least for a week. The cannulae are placed intravascularly through the femoral artery and vein by using the Seldinger's percutaneous method. In an emergency situation, the arterial and venous cannulations are carried out separately on the both inguinal regions to save time. The tip of the venous cannula is adjusted to be placed near the right atrium under fluoroscopy. Initiation of ECPB via the femoro-femoral V-A cannulae assures instant and stable supply of oxygenated blood to all of the vital organs. At the present time, nothing is more important than a quick supply of oxygenated blood to the brain to ameliorate the post-ischemic brain damage.

    Abstract Patients with multiple traumas associated with cardiopulmonary failure have a high mortality rate; however, such patients can be temporarily stabilized using extracorporeal membrane oxygenation (ECMO), providing a bridge to rescue therapy. Using a retrospective study design, we aimed to clarify the prognostic factors of post-traumatic ECMO support. From March 2006 to July 2016, 43 adult patients (mean age, 37.3 ± 15.2 years; 7 females [16.3%]) underwent ECMO because of post-traumatic cardiopulmonary failure. Pre-ECMO demographics, peri-ECMO events, and post-ECMO recoveries were compared between survivors and nonsurvivors. The most common traumatic insult was traffic collision (n = 30, 69.8%), and involved injury areas included the chest (n = 33, 76.7%), head (n = 14, 32.6%), abdomen (n = 21, 48.8%), and fractures (n = 21, 48.8%). Fifteen patients (34.9%) underwent cardiopulmonary resuscitation and 22 (51.2%) received rescue interventions before ECMO deployment. The mean time interval between trauma and ECMO was 90.6 ± 130.1 hours, and the mode of support was venovenous in 26 patients (60.5%). A total of 26 patients (60.5%) were weaned off of ECMO and 22 (51.6%) survived to discharge, with an overall mean support time of 162.9 ± 182.7 hours. A multivariate regression analysis identified 2 significant predictors for in-hospital mortality: an injury severity score (ISS) >30 (odds ratio [OR], 9.48; 95% confidence interval [CI], 1.04–18.47; P = 0.042), and the requirement of renal replacement therapy (RRT) during ECMO (OR, 8.64; 95% CI, 1.73–26.09; P = 0.020). These two factors were also significant for the 1-year survival (ISS >30: 12.5%; ISS ≤30, 48.1%, P = 0.001) (RRT required, 15.0%; RRT not required, 52.2%, P = 0.006). Using ECMO in selected traumatized patients with cardiopulmonary failure can be a salvage therapy. Prompt intervention before shock-impaired systemic organ perfusion and acute

    Use of cardiopulmonary bypass for emergency resuscitation is not new. In fact, John Gibbon proposed this concept for the treatment of severe pulmonary embolism in 1937. Significant progress has been made since, and two main concepts for cardiac assist based on cardiopulmonary bypass have emerged: cardiopulmonary support (CPS) and extracorporeal membrane oxygenation (ECMO). The objective of this review is to summarize the state of the art in these two technologies. Configuration of CPS is now fairly standard. A mobile cart with relatively large wheels allowing for easy transportation carries a centrifugal pump, a back-up battery with a charger, an oxygen cylinder, and a small heating system. Percutaneous cannulation, pump-driven venous return, rapid availability, and transportability are the main characteristics of a CPS system. Cardiocirculatory arrest is a major predictor of mortality despite the use of CPS. In contrast, CPS appears to be a powerful tool for patients in cardiogenic shock before cardiocirculatory arrest, requiring some type of therapeutic procedures, especially repair of anatomically correctable problems or bridging to other mechanical circulatory support systems such as ventricular assist devices. CPS is in general not suitable for long-term applications because of the small-bore cannulas, resulting in significant pressure gradients and eventually hemolysis. In contrast, ECMO can be designed for longer-term circulatory support. This requires large-bore cannulas and specifically designed oxygenators. The latter are either plasma leakage resistent (true membranes) or relatively thrombo-resistant (heparin coated). Both technologies require oxygenator changeovers although the main reason for this is different (clotting for the former, plasma leakage for the latter). Likewise, the tubing within a roller pump has to be displaced and centrifugal pump heads have to be replaced over time. ECMO is certainly the first choice for a circulatory support system

    Each year in the US, some four hundred thousand newborns need help breathing when they are born. Due to the frequent need for resuscitation at birth, it is vital to have evidence-based care guidelines and to provide effective neonatal resuscitation training. Every five years, the International Liaison Committee on Resuscitation (ILCOR) reviews the science of neonatal resuscitation. In the US, the American Heart Association (AHA) develops treatment guidelines based on the ILCOR science review, and the Neonatal Resuscitation Program (NRP) translates the AHA guidelines into an educational curriculum. In this report, we review recent advances in neonatal resuscitation training and practice. We begin with a review of the new 7th edition NRP training curriculum.

    Objective: Do-not-resuscitate (DNR) orders and advance directives are increasingly prevalent and may affect medical interventions and outcomes. Simple, automated techniques to identify patients with DNR orders do not currently exist but could help avoid costly and time-consuming chart review. This study hypothesized that a decision to withhold cardiopulmonary resuscitation would be included in a patient's dictated reports. The authors developed and validated a simple computerized search method, which screens dictated reports to detect patients with DNR status. Methods A list of concepts related to DNR order documentation was developed using emergency department, hospital admission, consult, and hospital discharge reports of 665 consecutive, hospitalized pneumonia patients during a four-year period (1995–1999). The list was validated in an independent group of 190 consecutive inpatients with pneumonia during a five-month period (1999–2000). The reference standard for the presence of DNR orders was manual chart review of all study patients. Sensitivity, specificity, predictive values, and nonerror rates were calculated for individual and combined concepts. Results The list of concepts included: DNR, Do Not Attempt to Resuscitate (DNAR), DNI, NCR, advanced directive, living will, power of attorney, Cardiopulmonary Resuscitation (CPR), defibrillation, arrest, resuscitate, code, and comfort care. As determined by manual chart review, a DNR order was written for 32.6% of patients in the derivation and for 31.6% in the validation group. Dictated reports included DNR order–related information for 74.5% of patients in the derivation and 73% in the validation group. If mentioned in the dictated report, the combined keyword search had a sensitivity of 74.2% in the derivation group (70.0% in the validation group), a specificity of 91.5% (81.5%), a positive predictive value of 80.9% (63.6%), a negative predictive value of 88.0% (85.5%), and a nonerror rate of 85.9% (77

    Code status discussions are important during a hospitalization, yet variation in its practice exists. No data have assessed the likelihood of patients to change code status following a cardiopulmonary arrest. A retrospective review of all patients that experienced a cardiopulmonary arrest between May 1, 2008 and June 30, 2014 at an academic medical center was performed. The proportion of code status modifications to do not resuscitate (DNR) from full code was assessed. Baseline clinical characteristics, resuscitation factors, and 24-h post-resuscitation, hospital, and overall survival rates were compared between the two subsets. A total of 157 patients survived the index event and were included. One hundred and fifteen (73.2%) patients did not have a change in code status following the index event, while 42 (26.8%) changed code status to DNR. Clinical characteristics were similar between subsets, although patients in the change to DNR subset were older (average age 67.7 years) compared to the full code subset (average age 59.2 years; p = 0.005). Patients in the DNR subset had longer overall resuscitation efforts with less attempts at defibrillation. Compared to the DNR subset, patients that remained full code demonstrated higher 24-h post-resuscitation (n = 108, 93.9% versus n = 32, 76.2%; p = 0.001) and hospital (n = 50, 43.5% versus n = 6, 14.3%; p = 0.001) survival rates. Patients in the DNR subset were more likely to have neurologic deficits on discharge and shorter overall survival. Patient code status wishes do tend to change during critical periods within a hospitalization, adding emphasis for continued code status evaluation. Copyright © 2015 Elsevier Ireland Ltd.

    Full Text Available Initial management of severely burned patient is similar with a trauma victim. Determination of airway patency, evaluation of respiration and circulation, early recognition of concomitant trauma has vital importance in burn patients. In the early phase, mortality mainly depends on missed or un-treated severe injuries or pathologies, but not burn injury itself.In patients that have TBSA greater than 15 %, fluid resuscitation should be started. In the first 24 hours, crystalloid solutions should be preferred. .Several formulas can guide fluid resuscitation; however the amount of fluid that is given to the patient should be individualized according to the patient’s need.

    BACKGROUND: Discussions on ethical aspects of life-and-death decisions within the hospital are often made in plenary. The prehospital physician, however, may be faced with ethical dilemmas in life-and-death decisions when time-critical decisions to initiate or refrain from resuscitative efforts...... need to be taken without the possibility to discuss matters with colleagues. Little is known whether these considerations regarding ethical issues in crucial life-and-death decisions are documented prehospitally. This is a review of the ethical considerations documented in the prehospital medical....... The medical records with possible documentation of ethical issues were independently reviewed by two philosophers in order to identify explicit ethical or philosophical considerations pertaining to the decision to resuscitate or not.

    Full Text Available Background. To propose hypovolemic shock as a possible explanation for the failure to resuscitate some babies after shoulder dystocia and to suggest a change in clinical practice. Case Presentation. Two cases are presented in which severe shoulder dystocia was resolved within five minutes. Both babies were born without a heartbeat. Despite standard resuscitation by expert neonatologists, no heartbeat was obtained until volume resuscitation was started, at 25 minutes in the first case and 11 minutes in the second. After volume resuscitation circulation was restored, there was profound brain damage and the babies died. Conclusion. Unsuspected hypovolemic shock may explain some cases of failed resuscitation after shoulder dystocia. This may require a change in clinical practice. Rather than immediately clamping the cord after the baby is delivered, it is proposed that (1 the obstetrician delay cord clamping to allow autotransfusion of the baby from the placenta and (2 the neonatal resuscitators give volume much sooner.

    Effective cardiopulmonary resuscitation saves lives. Health professionals who care for acutely unwell children need to be prepared to care for a child in arrest. Hospitals must ensure that their staff have the knowledge, confidence and ability to respond to a child in cardiac arrest. RESUS4KIDS is a programme designed to teach paediatric resuscitation to health care professionals who care for acutely unwell children. The programme is delivered in two components: an e-learning component for pre-learning, followed by a short, practical, face-to-face course that is taught using the round-the-table teaching approach. Round-the-table teaching is a novel, evidence-based small group teaching approach designed to teach paediatric resuscitation skills and knowledge. Round-the-table teaching uses a structured approach to managing a collapsed child, and ensures that each participant has the opportunity to practise the essential resuscitation skills of airway manoeuvres, bag mask ventilation and cardiac compressions. Round-the-table teaching is an engaging, non-threatening approach to delivering interdisciplinary paediatric resuscitation education. The methodology ensures that all participants have the opportunity to practise each of the different essential skills associated with the Danger, Response, Send for help, Airway, Breathing, Circulation, Defibrillation or rhythm recognition (DRSABCD) approach to the collapsed child. Round-the-table teaching is based on evidence-based small group teaching methods. The methodology of round-the-table teaching can be applied to any topic where participants must demonstrate an understanding of a sequential approach to a clinical skill. Round-the-table teaching uses a structured approach to managing a collapsed child. © 2014 The Authors.

    To investigate the effects of bed width on the quality of chest compressions during simulated in-hospital resuscitation. Each candidate performed two 2-minute cycles of compression-only cardiopulmonary resuscitation on an adult manikin placed on either an emergency stretcher (narrow bed) or a standard hospital bed (wide bed) in random order at 1 day intervals. We conducted subjective assessments of cardiopulmonary resuscitation quality and rescuer fatigue at the end of each session, using surveys. There were no significant differences between narrow and wide bed sessions in either mean depth or the percentage of compressions with adequate depth (P=.56 and .58, respectively). The mean rate of compressions and the percentage of compressions with adequate rate were also similar between sessions (P=.24 and .27, respectively). However, the percentage of correct hand position and complete chest recoil was significantly higher in the narrow bed session than in the wide bed session (P=.02 and .02, respectively). In addition, survey results showed that rescuers felt more comfortable and less exhausted in the narrow bed session compared with the wide bed session (Phospital bed. Therefore, we propose a narrow bed for critically ill inpatients with high risk of cardiac arrest. Copyright © 2016 Elsevier Inc. All rights reserved.

    Background The current theory of dyspnea perception presumes a multidimensional conception of dyspnea.However,its validity in patients with cardiopulmonary dyspnea has not been investigated.Methods A respiratory symptom checklist incorporating spontaneously reported descriptors of sensory experiences of breathing discomfort,affective aspects,and behavioral items was administered to 396 patients with asthma,chronic obstructive pulmonary disease (COPD),diffuse parenchymal lung disease,pulmonary vascular disease,chronic heart failure,and medically unexplained dyspnea.Symptom factors measuring different qualitative components of dyspnea were derived by a principal component analysis.The separation of patient groups was achieved by a variance analysis on symptom factors.Results Seven factors appeared to measure three dimensions of dyspnea:sensory (difficulty breathing and phase of respiration,depth and frequency of breathing,urge to breathe,wheeze),affective (chest tightness,anxiety),and behavioral (refraining from physical activity) dimensions.Difficulty breathing and phase of respiration occurred more often in COPD,followed by asthma (R2=0.12).Urge to breathe was unique for patients with medically unexplained dyspnea (R2=0.12).Wheeze occurred most frequently in asthma,followed by COPD and heart failure (R2=0.17).Chest tightness was specifically linked to medically unexplained dyspnea and asthma (R2=0.04).Anxiety characterized medically unexplained dyspnea (R2=0.08).Refraining from physical activity appeared more often in heart failure,pulmonary vascular disease,and COPD (R2=0.15).Conclusions Three dimensions with seven qualitative components of dyspnea appeared in cardiopulmonary disease and the components under each dimension allowed separation of different patient groups.These findings may serve as a validation on the multiple dimensions of cardiopulmonary dyspnea.

    2015-06-01

    The development of cardiopulmonary bypass (CPB), thereby permitting open-heart surgery, is one of the most important advances in medicine in the 20th century. Many currently practicing cardiac anesthesiologists, cardiac surgeons, and perfusionists are unaware of how recently it came into use (60 years) and how much the practice of CPB has changed during its short existence. In this paper, the development of CPB and the many changes and progress that has taken place over this brief period of time, making it a remarkably safe endeavor, are reviewed. The many as yet unresolved questions are also identified, which sets the stage for the other papers in this issue of this journal.

  11. Cooling strategies and transport theories for brain hypothermia resuscitation

    The brain is one of the most important organs in a biological body whose normal function depends heavily on an uninterrupted delivery of oxygen.Unlike skeletal muscles that can survive for hours without oxygen,neuron cells in the brain are easily subjected to an irreversible damage within minutes from the onset of oxygen deficiency.With the interruption of cardiopulmonary circulation in many cardiac surgical procedures or accidental events leading to cerebral circulation arrest,an imbalance between energy production and consumption will occur which causes a rapid depletion of oxygen due to the interrupted blood-flow to the brain.Meanwhile,the cooling function of the blood flow on the hot tissue will be stopped,while metabolic heat generation in the tissues still keeps running for awhile.Under such adverse situations,the potential for cerebral protection through hypothermia has been intensively investigated in clinics by lowering brain temperature to restrain the cerebral oxygen demands.The reason can be attributed to the decreased metabolic requirements of the cold brain tissues,which allows a longer duration for the brain to endure reduced oxygen delivery.It is now clear that hypothermia would serve as the principal way for neurologic protection in a wide variety of emergency medicines,especially in cerebral damage,anoxia,circulatory arrest,respiratory occlusion,etc.However,although brain cooling has been found uniquely significant in clinical practices,the serious lack of knowledge on the mechanisms involved prevents its further advancement in brain resuscitation.Compared with the expanded trials in clinics,only very limited efforts were made to probe the engineering issues involved,which turns out to be a major obstacle for the successful operation of brain hypothermia resuscitation.From the viewpoint of biothermal medical engineering,the major theories and strategies for administering brain cooling can generally be classified into three categories:heat transfer

    There is strong evidence to suggest that angiotensin-converting enzyme inhibitors (ACEIs) protect against local myocardial ischemia/reperfusion (I/R) injury. This study was designed to explore whether ACEIs exert cardioprotective effects in a swine model of cardiac arrest (CA) and resuscitation. Male pigs were randomly assigned to three groups: sham-operated group, saline treatment group and enalapril treatment group. Thirty minutes after drug infusion, the animals in the saline and enalapril groups were subjected to ventricular fibrillation (8 min) followed by cardiopulmonary resuscitation (up to 30 min). Cardiac function was monitored, and myocardial tissue and blood were collected for analysis. Enalapril pre-treatment did not improve cardiac function or the 6-h survival rate after CA and resuscitation; however, this intervention ameliorated myocardial ultrastructural damage, reduced the level of plasma cardiac troponin I and decreased myocardial apoptosis. Plasma angiotensin (Ang) II and Ang-(1–7) levels were enhanced in the model of CA and resuscitation. Enalapril reduced the plasma Ang II level at 4 and 6 h after the return of spontaneous circulation whereas enalapril did not affect the plasma Ang-(1–7) level. Enalapril pre-treatment decreased the myocardial mRNA and protein expression of angiotensin-converting enzyme (ACE). Enalapril treatment also reduced the myocardial ACE/ACE2 ratio, both at the mRNA and the protein level. Enalapril pre-treatment did not affect the upregulation of ACE2, Ang II type 1 receptor (AT1R) and MAS after CA and resuscitation. Taken together, these findings suggest that enalapril protects against ischemic injury through the attenuation of the ACE/Ang II/AT1R axis after CA and resuscitation in pigs. These results suggest the potential therapeutic value of ACEIs in patients with CA. PMID:27633002

    There is an increasing interest in human factors within the healthcare environment reflecting the understanding of their impact on safety. The aim of this paper is to explore how human factors might be taught on resuscitation courses, and improve course outcomes in terms of improved mortality and morbidity for patients. The delivery of human factors training is important and this review explores the work that has been delivered already and areas for future research and teaching. Medline was searched using MESH terms Resuscitation as a Major concept and Patient or Leadership as core terms. The abstracts were read and 25 full length articles reviewed. Critical incident reporting has shown four recurring problems: lack of organisation at an arrest, lack of equipment, non functioning equipment, and obstructions preventing good care. Of these, the first relates directly to the concept of human factors. Team dynamics for both team membership and leadership, management of stress, conflict and the role of debriefing are highlighted. Possible strategies for teaching them are discussed. Four strategies for improving human factors training are discussed: team dynamics (including team membership and leadership behaviour), the influence of stress, debriefing, and conflict within teams. This review illustrates how human factor training might be integrated further into life support training without jeopardising the core content and lengthening the courses.

    Quantitative electroencephalogram (EEG) analysis has shown promising results in studying brain injury and functional recovery after cardiac arrest (CA). However, whether the quantitative characteristics of EEG, as potential indicators of neurological prognosis, are influenced by CA causes is unknown. The purpose of this study was designed to compare the quantitative characteristics of early post-resuscitation EEG between asphyxial CA (ACA) and ventricular fibrillation CA (VFCA) in rats. Thirty-two Sprague-Dawley rats of both sexes were randomized into either ACA or VFCA group. Cardiopulmonary resuscitation was initiated after 5-min untreated CA. Characteristics of early post-resuscitation EEG were compared, and the relationships between quantitative EEG features and neurological outcomes were investigated. Compared with VFCA, serum level of S100B, neurological deficit score and brain histopathologic damage score were dramatically higher in the ACA group. Quantitative measures of EEG, including onset time of EEG burst, time to normal trace, burst suppression ratio, and information quantity, were significantly lower for CA caused by asphyxia and correlated with the 96-h neurological outcome and survival. Characteristics of earlier post-resuscitation EEG differed between cardiac and respiratory causes. Quantitative measures of EEG not only predicted neurological outcome and survival, but also have the potential to stratify CA with different causes.

  15. Acute mesenteric ischemia after cardio-pulmonary bypass surgery

    2008-01-01

    Acute mesenteric ischemia (AMI) is a highly-lethal surgical emergency.Several pathophysiologic events (arterial obstruction,venous thrombosis and diffuse vasospasm) lead to a sudden decrease in mesenteric blood flow.Ischemia/reperfusion syndrome of the intestine is responsible for systemic abnormalities,leading to multi-organ failure and death.Early diagnosis is difficult because the clinical presentation is subtle,and the biological and radiological diagnostic tools lack sensitivity and specificity.Therapeutic options vary from conservative resuscitation,medical treatment,endovascular techniques and surgical resection and revascularization.A high index of suspicion is required for diagnosis,and prompt treatment is the only hope of reducing the mortality rate.Studies are in progress to provide more accurate diagnostic tools for early diagnosis.AMI can complicate the post-operative course of patients following cardio-pulmonary bypass (CPB).Several factors contribute to the systemic hypo-perfusion state,which is the most frequent pathophysiologic event.In this particular setting,the clinical presentation of AMI can be misleading,while the laboratory and radiological diagnostic tests often produce inconclusive results.The management strategies are controversial,but early treatment
