    The American Heart Association and the European Resuscitation Council recently recommended that vasopressin can be used for cardiopulmonary resuscitation, instead of epinephrine. However, the guidelines do not discuss the effects of vasopressin during cerebral resuscitation. In this study, we intraperitoneally injected epinephrine and/or vasopressin during cardiopulmonary resuscitation in a rat model of asphyxial cardiac arrest. The results demonstrated that, compared with epinephrine alone, ...

    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.

    Full Text Available Cardiopulmonary arrest is a medical emergency in which the lapse of time between event onset and the initiation of measures of basic and advanced support, as well as the correct care based on specific protocols for each clinical situation, constitute decisive factors for a successful therapy. Cardiopulmonary arrest care cannot be restricted to the hospital setting because of its fulminant nature. This necessitates the creation of new concepts, strategies and structures, such as the concept of life chain, cardio-pulmonary resuscitation courses for professionals who work in emergency medical services, the automated external defibrillator, the implantable cardioverter-defibrillator, and mobile intensive care units, among others. New concepts, strategies and structures motivated by new advances have also modified the treatment and improved the results of cardiopulmonary resuscitation in the hospital setting. Among them, we can cite the concept of cerebral resuscitation, the application of the life chain, the creation of the universal life support algorithm, the adjustment of drug doses, new techniques - measure of the end-tidal carbon dioxide levels and of the coronary perfusion pressure - and new drugs under research.

    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.

    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.

    2016-01-01

    Background The use of extracorporeal life support (ECLS) in the setting of cardiopulmonary resuscitation (CPR) has shown improved outcomes compared with conventional CPR. The aim of this study was to determine factors predictive of survival in extracorporeal CPR (E-CPR). Methods Consecutive 85 adult patients (median age, 59 years; range, 18 to 85 years; 56 males) who underwent E-CPR from May 2005 to December 2012 were evaluated. Results Causes of arrest were cardiogenic in 62 patients (72.9%), septic in 18 patients (21.2%), and hypovolemic in 3 patients (3.5%), while the etiology was not specified in 2 patients (2.4%). The survival rate in patients with septic etiology was significantly poorer compared with those with another etiology (0% vs. 24.6%, p=0.008). Septic etiology (hazard ratio [HR], 2.84; 95% confidence interval [CI], 1.49 to 5.44; p=0.002) and the interval between arrest and ECLS initiation (HR, 1.05 by 10 minutes increment; 95% CI, 1.02 to 1.09; p=0.005) were independent risk factors for mortality. When the predictive value of the E-CPR timing for in-hospital mortality was assessed using the receiver operating characteristic curve method, the greatest accuracy was obtained at a cutoff of 60.5 minutes (area under the curve, 0.67; 95% CI, 0.54 to 0.80; p=0.032) with 47.8% sensitivity and 88.9% specificity. The survival rate was significantly different according to the cutoff of 60.5 minutes (p=0.001). Conclusion These results indicate that efforts should be made to minimize the time between arrest and ECLS application, optimally within 60 minutes. In addition, E-CPR in patients with septic etiology showed grave outcomes, suggesting it to be of questionable benefit in these patients. PMID:27525236

    Full Text Available Abstract Background Acute posthypoxic myoclonus (PHM can occur in patients admitted after cardiopulmonary resuscitation (CPR and is considered to have a poor prognosis. The origin can be cortical and/or subcortical and this might be an important determinant for treatment options and prognosis. The aim of the study was to investigate whether acute PHM originates from cortical or subcortical structures, using somatosensory evoked potential (SEP and electroencephalogram (EEG. Methods Patients with acute PHM (focal myoclonus or status myoclonus within 72 hours after CPR were retrospectively selected from a multicenter cohort study. All patients were treated with hypothermia. Criteria for cortical origin of the myoclonus were: giant SEP potentials; or epileptic activity, status epilepticus, or generalized periodic discharges on the EEG (no back-averaging was used. Good outcome was defined as good recovery or moderate disability after 6 months. Results Acute PHM was reported in 79/391 patients (20%. SEPs were available in 51/79 patients and in 27 of them (53% N20 potentials were present. Giant potentials were seen in 3 patients. EEGs were available in 36/79 patients with 23/36 (64% patients fulfilling criteria for a cortical origin. Nine patients (12% had a good outcome. A broad variety of drugs was used for treatment. Conclusions The results of this study show that acute PHM originates from subcortical, as well as cortical structures. Outcome of patients admitted after CPR who develop acute PHM in this cohort was better than previously reported in literature. The broad variety of drugs used for treatment shows the existing uncertainty about optimal treatment.

  20. Cardiopulmonary resuscitation and contrast media reactions in a radiology department

    International Nuclear Information System (INIS)

    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).

    2013-01-01

    Full Text Available Wrist pain in rescuers performing chest compressions as part of cardiopulmonary resuscitation has been reported anecdotally and recently in the literature. Studies have indicated that rescuers apply as much as 644 N of force to the victim′s chest with each compression, while standards require one hundred compressions per minute. Recent research suggests that forces transmitted through the rescuers′ wrists of less than 10% of those seen during the performance of chest compressions significantly strain the scapholunate ligament. Biomechanical research should be performed to further evaluate this possible correlation. Compensation for worker injury maybe involved.

Pulsatile force was applied to the sternum in increments to determine the effects of increasing compression on chest geometry and intrathoracic vascular pressures. In 2-wk- and 1-mo-old piglets, permanent changes in chest shape developed due to incomplete recoil of the chest along the anteroposterior axis, and large intrathoracic vascular pressures were generated. In 3-mo-old animals, permanent chest deformity did not develop, and large intrathoracic vascular pressures were not produced. We propose a theoretical model of the chest as an elliptic cylinder. Pulsatile displacement along the minor axis of an ellipse produces a greater decrease in cross-sectional area than displacement of a circular cross section. As thoracic cross section became less circular due to deformity, greater changes in thoracic volume, and hence pressure, were produced. With extreme deformity at high force, pulsatile displacement became limited, diminishing pressure generation. We conclude that changes in chest geometry are important in producing intrathoracic intravascular pressure during conventional cardiopulmonary resuscitation in piglets. PMID:3610916

    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

    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.

    Full Text Available Abstract Background Optimal manual closed chest compressions are difficult to give. A mechanical compression/decompression device, named LUCAS, is programmed to give compression according to the latest international guidelines (2005 for cardiopulmonary resuscitation (CPR. The aim of the present study was to compare manual CPR with LUCAS-CPR. Methods 30 kg pigs were anesthetized and intubated. After a base-line period and five minutes of ventricular fibrillation, manual CPR (n = 8 or LUCAS-CPR (n = 8 was started and run for 20 minutes. Professional paramedics gave manual chest compression's alternating in 2-minute periods. Ventilation, one breath for each 10 compressions, was given to all animals. Defibrillation and, if needed, adrenaline were given to obtain a return of spontaneous circulation (ROSC. Results The mean coronary perfusion pressure was significantly (p Conclusions LUCAS-CPR gave significantly higher coronary perfusion pressure and significantly fewer rib fractures than manual CPR in this porcine model.

  15. 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.

  16. Family presence during cardiopulmonary resuscitation: who should decide?

    2014-05-01

    Whether to allow the presence of family members during cardiopulmonary resuscitation (CPR) has been a highly contentious topic in recent years. Even though a great deal of evidence and professional guidelines support the option of family presence during resuscitation (FPDR), many healthcare professionals still oppose it. One of the main arguments espoused by the latter is that family members should not be allowed for the sake of the patient's best interests, whether it is to increase his chances of survival, respect his privacy or leave his family with a last positive impression of him. In this paper, we examine the issue of FPDR from the patient's point of view. Since the patient requires CPR, he is invariably unconscious and therefore incompetent. We discuss the Autonomy Principle and the Three-Tiered process for surrogate decision making, as well as the Beneficence Principle and show that these are limited in providing us with an adequate tool for decision making in this particular case. Rather, we rely on a novel principle (or, rather, a novel specification of an existing principle) and a novel integrated model for surrogate decision making. We show that this model is more satisfactory in taking the patient's true wishes under consideration and encourages a joint decision making process by all parties involved. PMID:23557910

  17. Do Radiologists Want/Need Training in Cardiopulmonary Resuscitation?

    International Nuclear Information System (INIS)

    Purpose: Prompt and effective cardiopulmonary resuscitation (CPR) decreases morbidity and mortality following cardiopulmonary arrest. Radiologists are frequently confronted with severely ill patients, who may deteriorate at any time. Furthermore, they have to be aware of life-threatening reactions towards contrast media. This study was designed to assess experience and self-estimation of German-speaking radiologists in CPR and cardiac defibrillation (CD). Material and Methods: 650 German-speaking radiologists were audited by a specially designed questionnaire, which was sent via e-mail. The answers were expected to be re-mailed within a 2-month period. Results: The response rate was 12.6%. 72.8% of the responders had performed at least 1 CPR (range 9.5 ± 13.1) and 37% at least 1 CD. 67.9% had had opportunities to attend training courses, which had been utilized by 41.8% of them. The last training of the responders was more than 2 years ago in 69.2% and more than 5 years ago in 37%. Of all responders 75.6% expressed the need for further education. Conclusion: The small response rate indicates the small importance of CPR in the subpopulation surveyed. The vast majority of the responders, however, showed interest in basic and advanced life support and advocated regular updates. It seems reasonable that radiological Dept. themselves should organize courses in order to cope with their specific situations

    Full Text Available Objectives. Studies have shown that healthcare personnel hesitate to perform defibrillation due to individual or organisational attitudes. We aimed to assess trainers’ attitudes towards cardiopulmonary resuscitation and defibrillation (CPR-D, Current Care Guidelines, and associated training. Methods. A questionnaire was distributed to CPR trainers attending seminars in Finland (N=185 focusing on the updated national Current Care Guidelines 2011. The questions were answered using Likert scale (1 = totally disagree, 7 = totally agree. Factor loading of the questionnaire was made using maximum likelihood analysis and varimax rotation. Seven scales were constructed (Hesitation, Nurse’s Role, Nontechnical Skill, Usefulness, Restrictions, Personal, and Organisation. Cronbach’s alphas were 0.92–0.51. Statistics were Student’s t-test, ANOVA, stepwise regression analysis, and Pearson Correlation. Results. The questionnaire was returned by 124/185, 67% CPR trainers, of whom two-thirds felt that their undergraduate training in CPR-D had not been adequate. Satisfaction with undergraduate defibrillation training correlated with the Nontechnical Skills scale (p<0.01. Participants scoring high on Hesitation scale (p<0.01 were less confident about their Nurse’s Role (p<0.01 and Nontechnical Skills (p<0.01. Conclusion. Quality of undergraduate education affects the work of CPR trainers and some feel uncertain of defibrillation. The train-the-trainers courses and undergraduate medical education should focus more on practical scenarios with defibrillators and nontechnical skills.

    2014-01-01

    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.

  2. A Reliable Method for Rhythm Analysis during Cardiopulmonary Resuscitation

    2014-01-01

    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 Background The number of casualties and critically ill patients referred to radiology departments increased during the past decade, which caused the risk of cardiac arrest in radiology departments to increase considerably. Objectives The current study aimed to evaluate the knowledge and attitude of radiology technologists regarding Cardiopulmonary Resuscitation (CPR. Patients and Methods After approval a cross sectional study was designed. Ninety five radiology technologists (male and female were selected in four tertiary referral hospitals in Ahvaz, Iran. Accordingly, 87 radiologic technologists of which agreed to participate in the study. The researchers developed a questionnaire. The questionnaire consisted of three distinct sections including demographic data, attitude, and technical knowledge questions. Reliability of the technical knowledge questions were evaluated using Cronbach’s alpha (76%. Data collection was performed using interview method. Results Of the total 87 questionnaires, one was incomplete. None of the participants had attended a training program since employment. The average scores of attitude towards CPR and technical knowledge were 80 ± 8.9 and 8.8 ± 2.3, respectively. A correlation was observed between age and work experience (r = 0.866, P ≤ 0.0001, age and technical knowledge (r = 0.380, P ≤ 0.0001, work experience and technical knowledge (r = 0.317, P = 0.003, and attitude and technical knowledge (r = 0.397, P ≤ 0.0001. Also a correlation was observed between work experience and attitude (r = 0.385, P ≤ 0.0001. No significant difference was observed between male and female subjects’ technical knowledge (P ≥ 0.05 and attitude (P ≥ 0.05. Conclusions It can be concluded that, although the attitude of participants towards CPR was positive in general, their technical knowledge was poor. This finding should urge decision-makers to consider delivering in-service training courses to radiology technologists

    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

    The objective of this prospective study was to assess the incidence and magnitude of fat emboli after cardiopulmonary resuscitation and intraosseous infusions. An animal laboratory at a university center was used to study 33 mixed-breed piglets. The piglets underwent hypoxic cardiac arrest followed by chest compressions and mechanical ventilation for a minimum of 30 minutes. The animals were divided in groups: group 1 (n = 5), which had no intraosseous cannulas, group 2 (n = 6), which had intraosseous cannulas with infusion, groups 3 (n = 6), 4 (n = 6), and 5 (n = 8), which had intraosseous cannulas with infusion of epinephrine, normal saline, and sodium bicarbonate respectively, and group 6 (n = 2), which was a sham group with no intraosseous cannulas and no cardiopulmonary resuscitation. At cessation of cardiopulmonary resuscitation, representative lung samples were collected from upper and lower lobes of each lung and observed for fat globules and bone marrow elements. Fat globules were seen in the peribronchial blood vessels and intravascular areas throughout all lung fields of groups 1 through 5. There was no difference in appearance or distribution of fat globules among the 5 treatment groups. Analysis of variance showed no statistical significance (P fat embolization over cardiopulmonary resuscitation alone in this animal model. The benefits of using this procedure in critically ill children as a means of rapid vascular access for resuscitation is well established. However, the risk of fat embolism in this population needs further study. PMID:9258208

    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.

    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.

    Objective: To measure end-tidal carbon dioxide pressure (PetCO2) in preset interval in order to evaluate the efficiency of cardiopulmonary resuscitation (CPR) performed on patients in cardiopulmonary arrest, evaluate the validity of PetCO2 in predicting the mortality and finally assess the PetCO2 levels of the patients in cardiopulmonary arrest based on the initial presenting rhythm. Methods: This prospective study was conducted at the Ankara Training and Research Hospital on patients who presented with cardiopulmonary arrest. Standard ACLS (Advanced Cardiac Life Support) protocols were performed. Patients were categorized in two groups based on their rhythms as Ventricular Fibrillation and Asystole. Patients’ PetCO2 values were recorded. Results: PetCO2 levels of the Return of Spontaneous Circulation (ROSC) group in the 5th, 10th, 15th and 20th minutes were significantly higher compared to the exitus group (p<0.001). In distinguishing ROSC and exitus, PetCO2 measurements within 5-20 minute intervals showed highest performance on the 20th and lowest on the 5th minutes. Conclusion: PetCO2 values are higher in the ROSC group. During the CPR, the most reliable time for ROSC estimation according to PetCO2 values is 20th minute. None of the patients who had PetCO2 levels less than 14 mmHg survived. PMID:24639823

    Parents of premature infants often receive infant cardiopulmonary resuscitation (CPR) training prior to discharge from the hospital, but one study showed that 27.5% of parents could not demonstrate adequate CPR skills after completing an instructor-led class. We hypothesized that parents who viewed an instructional video on infant CPR before attending the class would perform better on a standardized skills test than parents who attended the class with no preparation. Parents randomized to the...

    Cardiopulmonary resuscitation (CPR) is an effective intervention for prehospital cardiac arrest. Despite all available training opportunities for CPR, disparities exist in participation in CPR training, CPR knowledge, and receipt of bystander CPR for certain ethnic groups. We conducted five focus groups with Chinese immigrants who self-reported limited English proficiency (LEP). A bilingual facilitator conducted all the sessions. All discussions were taped, recorded, translated, and trans...

    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 performi...

    Postcardiac arrest syndrome yields poor neurological outcomes, but the mechanisms underlying this condition remain poorly understood. This study investigated whether endoplasmic reticulum (ER) stress-mediated apoptosis is induced in injured brain after resuscitation. Sprague-Dawley rats were subjected to 6 min of cardiac arrest (CA) and then resuscitated successfully. In the first experiment, animals were sacrificed 1, 3, 6, 12, or 24 h (n = 3 per group) after successful cardiopulmonary resuscitation. Brain tissues were analyzed by real-time polymerase chain reaction and Western blotting. In the second experiment, either dimethyl sulfoxide or salubrinal (Sal; 1 mg/kg), an ER stress inhibitor, was injected 30 min before the induction of CA (n = 10 per group). Neurological deficits were evaluated 24 h after CA. Brain specimens were analyzed using electron microscopy, terminal deoxynucleotidyl transferase dUTP nick end labeling assays and immunohistochemistry. We found that the messenger RNA and protein levels of glucose-regulated protein 78, X-box binding protein 1, C/EBP homologous protein, and caspase 12 were significantly elevated after resuscitation. We also observed that rats treated with Sal exhibited an improved neurological deficit score (32.3 ± 15.5 in the Sal group vs. 49.8 ± 20.9 in controls, P < 0.05). In addition, morphological improvements in the hippocampal ER were observed in the Sal group compared with the dimethyl sulfoxide group 24 h after reperfusion. Furthermore, in situ immunostaining revealed that markers of ER stress were significantly inhibited by Sal pretreatment. Our findings suggested that ER stress and the associated apoptotic pathways were activated in the hippocampus after resuscitation. Administration of Sal 30 min before cardiopulmonary resuscitation ameliorated neurological dysfunction 24 h after CA, possibly through the inhibition of ER stress after postresuscitation brain injury.

    Full Text Available Aim We have studied epidemiology of in-hospital cardiac arrest, characteristics of organizing a reanimationand its,procedures as well as its documenting.Methods We analyzed all resuscitation procedure data where anesthesiology reanimation teams (RT providedcardiopulmonary resuscitation (CPR during one-year period. We included resuscitation attemptsthat were initiated outside the Department of Anesthesiology, excluding incidents in operation rooms andIntensive Care Unit (ICU. Data on every cardiac arrest and CPR were entered in a special form.Results During one-year period 87 CPR were performed. Victims of cardiac arrest were principallyelderly patients (age 60 – 80, mostly male (60%. Most frequent victims were neurological patients(42%, surgical patients (21% and neurosurgical patients (10%. The leading cause of cardiac arrestwas primary heart disease, following neurological diseases and respiration disorders of severe etiology.In over 90% cases CPR was initiated by medical personnel in their respective departments, RT arrivedwithin 5 minutes in 73,56% cases. Initially survival was 32%, but full recovery was accomplished in 4patients out of 87 (4,6%.Conclusion Victims of cardiac arrest are patients whose primary disease contributes to occurrence ofcardiorespiratory complications. High mortality and low percentage of full recovery can be explainedby characteristics of patients (old age, nature and seriousness of primary disease which significantly affectthe outcome of CPR. In some cases a question is raised whether to initiate the CPR at all. We wouldlike to point out that continous monitoring of potentially critical patients may prevent cardiorespiratoryincidents whereas the quality and success of CPR may be improved by training of staff and better technicalequipment on the relevant locations in the in the hospital where such incidents usually occur.

    Automatic suspension of do-not-resuscitate (DNR) orders during general anesthesia does not sufficiently address a patient's right to self-determination and is a practice still observed among anesthesiologists today. To provide an evidence base for ethical management of DNR orders during anesthesia and surgery, the authors performed a systematic review of the literature to quantify the survival after perioperative cardiopulmonary resuscitation (CPR). Results show that the probability of surviving perioperative CPR ranged from 32.0 to 55.7% when measured within the first 24 h after arrest with a neurologically favorable outcome expectancy between 45.3 and 66.8% at follow-up, which suggests a viable survival of approximately 25%. Because CPR generally proves successful in less than 15% of out-of-hospital cardiac arrests, the altered outcome probabilities that the conditions in the operating room bring on warrant reevaluation of DNR orders during the perioperative period. By preoperatively communicating the evidence to patients, they can make better informed decisions while reducing the level of moral distress that anesthesiologists may experience when certain patients decide to retain their DNR orders.

  13. Are the current guideline recommendations for neonatal cardiopulmonary resuscitation safe and effective?

    2016-08-01

    A recently published review of approaches to optimize chest compressions in the resuscitation of asphyxiated newborns discussed the current recommendations and explored potential determinants of effective neonatal cardiopulmonary resuscitation (CPR). However, not all potential determinants of effective neonatal CPR were explored. Chest compression shallower than the current guideline recommendation of approximately 33% of the anterior-posterior (AP) chest diameter may be safer and more effective. From a physiological standpoint, high-velocity brief duration shallower compression may be more effective than current recommendations. The application of a 1- or 2-finger method of high-impulse CPR, which would depend on the size of the subject, may be more effective than using a 2-thumb (TT) encircling hands method of CPR. Adrenaline should not be used in the treatment of asphyxiated neonates and when necessary titrated vasopressin should be used. PMID:27220864

    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.

    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.

    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.

    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.

    Full Text Available Despite efforts to save more people suffering from in-hospital cardiac arrest, rates of survival after in-hospital cardiopulmonary resuscitation (CPR are no better today than they were more than a decade ago. This study was undertaken to assess the demographics, clinical parameters and outcomes of patients undergoing CPR by the code blue team at our center during 2001 to 2008. Data were collected retrospectively from adult patients (n=2262 who underwent CPR. Clinical outcomes of interest were survival at the end of CPR and survival at discharge from the hospital. Factors associated with survival were evaluated using binomial and Chi Square tests. Of the patients included (n=2262, 741 patients (32.8% had successful CPR. The number of male patients requiring CPR was more than females in need of the procedure. The majority of patients requiring CPR were older than 60 years (56.4±17.9. The number of successful CPR cases in long-day shift (7:00 to 19:00 was more than that in the night shift (19:00 to 7:00. Furthermore, 413 (18.4% cases were resuscitated on holidays and 1849 (81.7% on the working days. The duration of CPR was 10 min or less in 710 (31.4% cases. Cardiopulmonary resuscitations which lasted less than 10 minutes were associated with better outcomes. The findings of the present study indicate that some manageable factors including the duration of CPR, working shift, working day (holiday or non-holiday could affect the CPR outcomes. The findings might also be taken as evidence to suggest that the allocation of more personnel in each shift especially in night shifts and holidays, planning to increase the personnel's CPR skills, and decreasing the waste time would result in the improvement of CPR outcome.

    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. PMID:27017090

    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. PMID:27015887

    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.

    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.

    2016-06-01

    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.

    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.

    Cardiac arrest can occur in any health care setting at any time, requiring nursing staff to be prepared to quickly and adequately perform basic cardiopulmonary resuscitation (CPR). Currently, the American Heart Association certifies health care providers in Basic Life Support (BLS) for a 2-year period, but evidence indicates that psychomotor skills decline well before the end of the certification time frame. Nurses in the ambulatory surgery setting expressed concern regarding their ability to implement CPR successfully, given the infrequent occurrence of cardiac and respiratory arrests. Using a study by Niles et al. as a model, the authors piloted the implementation of brief CPR refresher training at the bedside of an ambulatory surgery center to assess and increase nurse confidence in BLS skills.

    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

    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.

    Full Text Available Objective: Important studies of cardiopulmonary resuscitation (CPR techniques influence the development of new guidelines. We systematically reviewed the efficacy of some important studies of CPR. Data Sources: The data analyzed in this review are mainly from articles included in PubMed and EMBASE, published from 1964 to 2014. Study Selection: Original articles and critical reviews about CPR techniques were selected for review. Results: The survival rate after out-of-hospital cardiac arrest (OHCA is improving. This improvement is associated with the performance of uninterrupted chest compressions and simple airway management procedures during bystander CPR. Real-time feedback devices can be used to improve the quality of CPR. The recommended dose, timing, and indications for adrenaline (epinephrine use may change. The appropriate target temperature for targeted temperature management is still unclear. Conclusions: New studies over the past 5 years have evaluated various aspects of CPR in OHCA. Some of these studies were high-quality randomized controlled trials, which may help to improve the scientific understanding of resuscitation techniques and result in changes to CPR guidelines.

    Ventricular fibrillation (VF) is observed as the initial rhythm in the majority of patients suffering from sudden cardiac arrest. It is vitally important to accurately recognize the initial VF rhythm and then implement electrical defibrillation. However, artifacts produced by chest compression during cardiopulmonary resuscitation (CPR) make the VF detection algorithms utilized by current automated external defibrillators (AEDs) unreliable. CPR must be traditionally interrupted for a reliable diagnosis. However, interruptions in chest compression have a deleterious effect on the success of defibrillation. The elimination of the CPR artifacts would enable compressions to continue during AED VF detection and thereby increase the likelihood of resuscitation success. We have estimated a model of this artifact by adaptively incorporating noise-assisted multivariate empirical mode decomposition (NA-MEMD) and least mean squares (LMS) and then removing the artifact from the corrupted ECGs. The simulation experiment indicated that the CPR artifact could be accurately modeled without any reference channels. We constructed a BP neural network to evaluate the results. A total of 372 VF and 645 normal sinus rhythm (SR) ECG samples were included in the analysis, and 24 CPR artifact signals were used to construct corrupted ECGs. The results indicated that at different SNR levels ranging from 0 to -12 dB, the sensitivity and specificity were always above 95 and 80 %, respectively. PMID:26831488

    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.

    Little is known about life-threatening events during gastrointestinal endoscopy (GIE). This study aimed to evaluate the clinical characteristics of emergency conditions requiring cardiopulmonary resuscitation (CPR) in GIE units and to assess the risk factors for mortality in these cases.We retrospectively collected life-threatening cases that occurred in the GIE units of 6 tertiary hospitals from January 2012 to June 2014. Cases were defined as alert calls for resuscitation teams in emergency situations of respiratory failure or cardiac arrest. Demographic data, clinical features, and probable causes were assessed. Factors associated with mortality were elucidated using logistic regression analysis.Among 263,426 endoscopies, 40 cases of CPR (0.015%) occurred during the period (male 67.5%, median age 62 yr). Gastrointestinal bleeding (GIB), such as hematemesis or melena, was the most common indication for endoscopy (55%). The types of clinical situations encountered were as follows: respiratory insufficiency (47.5%), decreased blood pressure (25%), and cardiac arrhythmia (25%). Although most of these conditions were detected during endoscopy (67.5%), one-third of cases (32.5%) were found before or after procedures. The most frequent probable cause of cases was aggravation of underlying diseases (57.5%), such as uncontrolled bleeding or exacerbation of lung disease. Despite efforts to resuscitate, 18 patients (45%) died. GIB was the single independent risk factor for mortality (odds ratio 28.45, 95% confidence interval 1.55-523.33, P = 0.024).Life-threatening situations requiring CPR can occur during endoscopy, even before or after the procedure. Greater attention should be paid while endoscopy is performed for GIB. PMID:26512621

    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

    International Nuclear Information System (INIS)

    Objective: To assess the level of awareness regarding basic and practical knowledge of cardiopulmonary resuscitation and its importance in the eyes of medical/dental students and doctors. Methods: The cross-sectional study was conducted in medical and dental colleges as well as hospitals of Rawalpindi and Islamabad, Pakistan, from June to September 2011. Non-probability convenience sampling was used and structured questionnaires on basic and practical knowledge of the procedure were distributed. The questionnaire had 26 items related to basic and advanced knowledge of the required skills. Doctors were divided into two groups based on their years of service and practice. Those with less than 5 years' experience were grouped as junior doctors, while rest as senior doctors. Descriptive statistics were employed to analyse the data using SPPS version 17 and Microsoft Excel. Percentages were worked out and the results were interpreted. Result: Of the 1000 questionnaires distributed, 646 (64.6%) were received duly filled and represented the study sample. Of the 646 participants, 34 (5.26%) were dentists, 424 (65.63%) were medical students, 92 (14.24%) were doctors and 96 (14.86%) were dental students. Basic knowledge of doctors was found to be better than that of dentists (n=96; 50% vs. n=8; 23%). Similarly, the advance knowledge of doctors was better than the dentists (n=53; 58% vs. n=11; 31%). The basic knowledge of junior doctors was found to be almost equal to the senior doctors (n=26; 44.75% vs. n=15; 45.5%). The advance knowledge of junior doctors was found to be better than the senior doctors (n=27; 45.37% vs. n=10; 29.48%). Among the students, 157 (37%) of the medical students had basic knowledge of CPR, while 36 (38%) dental students had basic knowledge of the topic. Medical students had more advanced knowledge (n=157; 37%) than dental students (n=34; 35%). Conclusion: The awareness of basic and advance knowledge of cardiopulmonary resuscitation skills in medical

    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.

    Vasopressin administration may be a promising therapy in the management of various shock states. In laboratory models of cardiac arrest, vasopressin improved vital organ blood flow, cerebral oxygen delivery, the rate of return of spontaneous circulation, and neurological recovery compared with epinephrine (adrenaline). In a study of 1219 adult patients with cardiac arrest, the effects of vasopressin were similar to those of epinephrine in the management of ventricular fibrillation and pulseless electrical activity; however, vasopressin was superior to epinephrine in patients with asystole. Furthermore, vasopressin followed by epinephrine resulted in significantly higher rates of survival to hospital admission and hospital discharge. The current cardiopulmonary resuscitation guidelines recommend intravenous vasopressin 40 IU or epinephrine 1mg in adult patients refractory to electrical countershock. Several investigations have demonstrated that vasopressin can successfully stabilize hemodynamic variables in advanced vasodilatory shock. Use of vasopressin in vasodilatory shock should be guided by strict hemodynamic indications, such as hypotension despite norepinephrine (noradrenaline) dosages >0.5 mug/kg/min. Vasopressin must never be used as the sole vasopressor agent. In our institutional routine, a fixed vasopressin dosage of 0.067 IU/min (i.e. 100 IU/50 mL at 2 mL/h) is administered and mean arterial pressure is regulated by adjusting norepinephrine infusion. When norepinephrine dosages decrease to 0.2 microg/kg/min, vasopressin is withdrawn in small steps according to the response in mean arterial pressure. Vasopressin also improved short- and long-term survival in various porcine models of uncontrolled hemorrhagic shock. In the clinical setting, we observed positive effects of vasopressin in some patients with life-threatening hemorrhagic shock, which had no longer responded to adrenergic catecholamines and fluid resuscitation.

    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

    Cerebral metabolic alterations during cardiac arrest, cardiopulmonary resuscitation (CPR) and extracorporeal cardiopulmonary life support (ECLS) are poorly explored. Markers are needed for a more personalized resuscitation and post—resuscitation care. Aim of this study was to investigate early metabolic changes in the hippocampal CA1 region during ventricular fibrillation cardiac arrest (VF-CA) and ECLS versus conventional CPR. Male Sprague-Dawley rats (350g) underwent 8min untreated VF-CA followed by ECLS (n = 8; bloodflow 100ml/kg), mechanical CPR (n = 18; 200/min) until return of spontaneous circulation (ROSC). Shams (n = 2) were included. Glucose, glutamate and lactate/pyruvate ratio were compared between treatment groups and animals with and without ROSC. Ten animals (39%) achieved ROSC (ECLS 5/8 vs. CPR 5/18; OR 4,3;CI:0.7–25;p = 0.189). During VF-CA central nervous glucose decreased (0.32±0.1mmol/l to 0.04±0.01mmol/l; p<0.001) and showed a significant rise (0.53±0.1;p<0.001) after resuscitation. Lactate/pyruvate (L/P) ratio showed a 5fold increase (31 to 164; p<0.001; maximum 8min post ROSC). Glutamate showed a 3.5-fold increase to (2.06±1.5 to 7.12±5.1μmol/L; p<0.001) after CA. All parameters normalized after ROSC with no significant differences between ECLS and CPR. Metabolic changes during ischemia and resuscitation can be displayed by cerebral microdialysis in our VF-CA CPR and ECLS rat model. We found similar microdialysate concentrations and patterns of normalization in both resuscitation methods used. Institutional Protocol Number: GZ0064.11/3b/2011 PMID:27175905

    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

    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.

    Full Text Available Cardiopulmonary resuscitation (CPR is an effective intervention for prehospital cardiac arrest. Despite all available training opportunities for CPR, disparities exist in participation in CPR training, CPR knowledge, and receipt of bystander CPR for certain ethnic groups. We conducted five focus groups with Chinese immigrants who self-reported limited English proficiency (LEP. A bilingual facilitator conducted all the sessions. All discussions were taped, recorded, translated, and transcribed. Transcripts were analyzed by content analysis guided by the theory of diffusion. The majority of participants did not know of CPR and did not know where to get trained. Complexity of CPR procedure, advantages of calling 9-1-1, lack of confidence, and possible liability discourage LEP individuals to learn CPR. LEP individuals welcome simplified Hands-Only CPR and are willing to perform CPR with instruction from 9-1-1 operators. Expanding the current training to include Hands-Only CPR and dispatcher-assisted CPR may motivate Chinese LEP individuals to get trained for CPR.

    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.

    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.

    2016-01-01

    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 CPR-IMFs amplitude differences. PMID:27529068

    We present an original method using a low cost accelerometer and a Kalman-filter based algorithm to monitor cardiopulmonary resuscitation chest compressions (CC) depth. A three-axis accelerometer connected to a computer was used during CC. A Kalman filter was used to retrieve speed and position from acceleration data. We first tested the algorithm for its accuracy and stability on surrogate data. The device was implemented for CC performed on a manikin. Different accelerometer locations were tested. We used a classical inertial navigation algorithm to reconstruct CPR depth and frequency. The device was found accurate enough to monitor CPR depth and its stability was checked for half an hour without any drift. Average error on displacement was ±0.5mm. We showed that depth measurement was dependent on the device location on the patient or the rescuer. The accuracy and stability of this small low-cost accelerometer coupled to a Kalman-filter based algorithm to reconstruct CC depth and frequency, was found well adapted and could be easily implemented.

    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.

    AIM: To introduce new applications into the ILCOR-cardiopulmonary resuscitation (CPR) “chain” sequence. METHODS: Stages of the CPR sequence (“chain”): prior to the application of chest massage: assess the victim’s state of consciousness and lung-heart failure; seek help (call 911), or in situations in which it is impossible to start the ILCOR protocol: (1) if the victim is trapped in car crash, overturned car, landslide, massive number of victims or catastrophe; or (2) delayed CPR. During chest compression: Yongquan is simultane- ously stimulated by a third rescuer. During defibrillator application: activate K-1 Yongquan through needles before defibrillation. Unsuccessful CPR: “gold standard” for legal clinical death. RESULTS: Implies comparing two hypotheses: Ho (null hypothesis) demonstrates no association between the two variables studied; Ha (alternative hypothesis) implies some degree of relation between them. Difference between the two treatments is observed. If it is greater than the standard error multiplied by a coefficient of security, the difference is significant: Ha will be accepted and Ho rejected. First we will compare CPR without defibrillator (method “A”) and K-1 Yongquan method (method “B”), using percentages of representative samples (treatment “A”: 6.4% response, treatment “B”: 85% response). If │PA - PB│ is greater than the product of 1.96 times the standard error, the difference is significant. Because │PA - PB│ = 0.786 is greater than 0.098, the difference between 0.064 and 0.85 is statistically significant. Thus, we reject Ho and accept Ha as correct. Thus, it is improbable that chance was responsible for this association. This analysis shows that K-1 Yongquan method has a “quality guarantee”. Second, we compare defibrillators (“A”) with K-1 Yongquan method (“B”) (treatment “A”: 48%, treatment “B”: 84%, │PA - PB│= 0.36; │PA - PB│ = 0.36 is greater than SE × 1.96 = 0.0148 and

    Full Text Available Aim: This study was undertaken to assess the demographics, clinical parameters and outcomes of patients undergoing cardiopulmonary resuscitation (CPR, by the code blue team at our center to compare with other centers. Materials and Methods: Data were collected retrospectively from all adult patients who underwent CPR at our hospital from 2007 to 2008. CPR was performed on 290 patients and it was given 313 times. Clinical outcomes of interest were survival at the end of CPR and survival at discharge from the hospital. Factors associated with survival were evaluated via binomial and chi square-tests. Results: Of the 290 patients included, 95 patients (30.4% had successful CPR. However, only 35 patients (12% were alive at discharge. The majority requiring CPR were above 60 years of age (61.7%. Males required CPR more than females. There were 125 women (43.1% and 165 males (56.9% aged 3 to 78 (average 59.6 years. Majority (179 of the cases (61.7% were above 60 years of age. Regarding the various wards, 54 cases (17.3% were in the internal medicine ward, 63 cases (20.1% in the surgery ward, 1 case (0.3% in the clinic, 11 cases (3.5% in the paraclinic, 116 cases (37.1% in the emergency (ER, 55 cases (17.5% in the Intensive Care Unit (ICU and Coronary Care Unit (CCU, and 13 cases (4.2% were in other wards. Cardiac massage was done in 133 cases (42.5%, defibrillation only via electroshock 3 cases (1%, and both were used in177 cases (56.5%. The ER had the most cases of CPR. Both cardiac massage and electroshock defibrillation were needed in most cases. Conclusion: In-hospital CPR for cardiopulmonary arrest was associated with 30.4% success at our center at the end of CPR but only 12% were alive at discharge. Duration of CPR> 10 minutes was predictive of significantly decreased survival to discharge.

    Objective 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. Design 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. Setting 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. Participants The study population comprised 25 participants, 9 school leadership members and 16 teachers. Results 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. Conclusions 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

    Nineteen anaesthetized piglets were investigated. After catheterization and a stabilization period, ventricular fibrillation was induced with a transthoracic DC shock, after which a 10-min period of cardiopulmonary resuscitation (CPR) took place. CPR included manual chest compression and mechanical ventilation with pure oxygen. After 1 min of CPR, an infusion of alkaline buffer was begun and completed within 5 min. A total of 50 mmol of either sodium bicarbonate (n = 6) or tris buffer mixture (n = 7) were given. These two groups were compared with a third control group (n = 6) receiving the same volume of normal saline. After 8 min of CPR all animals were given 0.5 mg adrenaline i.v., and after 10 min DC shocks were used to revert the heart back to normal sinus rhythm. Our results demonstrate that blood flow and not ventilation is the limiting factor for the efficient disposal of CO2 during CPR. This also applied when the demand for CO2 transport was increased by administration of sodium bicarbonate. The respiratory exchange ratio increased 1.9-fold, indicating that the transport of carbon dioxide was less affected than that of oxygen. The estimated alveolo-arterial oxygen tension difference, shunt, and overall ventilation/perfusion ratio increased, creating an inverse hyperbolic relationship between arterial PCO2 and PO2. The difference between mixed venous and arterial PCO2 correlated well to the mixed venous PCO2, implying more efficient pulmonary elimination of PCO2 when the mixed venous PCO2 was high. Pulmonary gas exchange during CPR appears to be independent of alkaline buffer therapy in the form of sodium bicarbonate or tris buffer mixture.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:1632165

    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.

    近年来,由于心肺复苏(cardiopulmonary resuscitation,CPR)后的低生存率状况始终没有得到根本性的改善,使人们开始更多的关注那些可能改善自主循环恢复(return of spontaneous circulation,ROSC)后的治疗手段.复苏后常规使用但又被忽视的治疗方式——氧疗(oxygen therapy)开始受到了关注.通过研究发现,不同的复苏后氧疗策略甚至可以影响心肺复苏的预后,为我们探索如何提高心肺复苏的成功率提供了新的研究方向.%In recent years, the people has shifted the focus from the interventions that improve success of cardiopulmonary resuscitation (CPR) to the methods that may modify the outcome favorably after return of spontaneous circulation ( ROSC) because of the disappointingly low survival rate following cardiac arrest. Oxygen therapy routinely administered during CPR has been paid attention. In light of the limited and conflicting data available from oxygen therapy strategy after CPR or ROSC, oxygen therapy even affects the prognosis, which provides a new way for us to explore in this field.

    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.

    In this series of animal experiments on resuscitation after cardiac arrest we had a unique opportunity to measure hyperspectral near-infrared spectroscopy (hNIRS) parameters directly on the brain dura, or on the brain through the intact pig skull, and simultaneously the muscle hNIRS parameters. Simultaneously the arterial blood pressure and carotid and femoral blood flow were recorded in real time using invasive sensors. We used a novel hyperspectral signalprocessing algorithm to extract time-dependent concentrations of water, hemoglobin, and redox state of cytochrome c oxidase during cardiac arrest and resuscitation. In addition in order to assess the validity of the non-invasive brain measurements the obtained results from the open brain was compared to the results acquired through the skull. The comparison of hNIRS data acquired on brain surface and through the adult pig skull shows that in both cases the hemoglobin and the redox state cytochrome c oxidase changed in similar ways in similar situations and in agreement with blood pressure and flow changes. The comparison of simultaneously measured brain and muscle changes showed expected differences. Overall the results show feasibility of transcranial hNIRS measurements cerebral parameters including the redox state of cytochrome oxidase in human cardiac arrest patients.

    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.

    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. PMID:27181515

    Cardiopulmonary resuscitation (CPR) is an effective way to rescue patients with cardiac arrest (CA) whose incidence rate has been increasing with the increase of cardiovascular and cerebrovascular diseases in recent years. After 50 years of exploration and practice of CPR, the survival rate on discharge of CA is far from satisfactory. While more efforts are being made to perfect CPR approach, the experience should be summarized and the misunderstanding should be avoided. We suggest that the main misunderstanding of CPR lies in stereotyped CPR procedure, CPR ventilation, CPR compression, open chest cardiac massage, CPR access, CPR back veneer and time limit are not adaptable to practice. We should work out a better method to guide CPR application in clinical practice.%心脏骤停威胁人们的生命健康,且近年随着心脑血管疾病增加其发病率逐渐攀升,心肺复苏(cardiopulmonaryresuscitation,CPR)作为抢救心脏骤停的有效方法,经过50余年的探索实践,患者的生存出院率仍不理想,故在发掘完善新方法的同时,亦应不断总结经验教训,找出CPR进程中的误区,笔者认为当前临床主要存在CPR程序“刻板化”、CPR通气“死腔化”、CPR按压“形式化”、CPR开胸“概念化”、CPR通路“单一化”、CPR背板“无声化”及CPR时限“教条化”,并结合经验积极尝试修正,以指导临床正确把握并实施CPR.

    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.

    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.

    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.

    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.

    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

    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.

    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.

    2008-11-01

    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

    Full Text Available JUSTIFICATIVA E OBJETIVOS: As novas diretrizes contêm modificações significativas para tentar melhorar a prática da reanimação e a sobrevida de pacientes com parada cardíaca. Este artigo teve por objetivo revisar as principais alterações na reanimação praticada pelo profissional de saúde. CONTEÚDO: São várias as novas recomendações quanto à reanimação cardiopulmonar (RCP, a maioria com a finalidade de prover boa circulação durante a parada cardíaca. A alteração mais importante é a ênfase na qualidade das compressões torácicas. A relação universal de 30:2 é recomendada para simplificar o treinamento, alcançar ótima freqüência delas e reduzir as interrupções. Choque único é aplicado quando indicado, seguido imediatamente de RCP. Este choque deve ser de 120 a 200J, quando onda bifásica ou 360J quando onda monofásica. Os socorristas nunca devem interromper as compressões torácicas para verificar o ritmo antes de terminar os 5 ciclos, ou aproximadamente 2 minutos de RCP. Após este período, se um ritmo organizado estiver presente, o profissional de saúde deve observar o pulso. Existem várias e pequenas alterações quanto aos fármacos administrados durante a RCP de acordo com o ritmo. Dada a falta de evidência de qualquer destes fármacos melhorar a sobrevida em longo prazo durante a parada cardíaca, a seqüência de RCP enfatiza muito mais o suporte básico de vida. CONCLUSÕES: É importante a atualização quanto às novas diretrizes de RCP para melhorar a qualidade da reanimação e alcançar melhores taxas de sobrevida dos pacientes críticos.BACKGROUND AND OBJECTIVES: New resuscitation guidelines contain significant changes intended to improve resuscitation practice and survival from cardiac arrest.

    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.

    Although some minor modifications were forged, the general consensus was to maintain most of the current guidelines for phone first/phone fast, no-assisted-ventilation CPR, the A-B-C (vs C-A-B) sequence of CPR, and the recovery position. The decisions to leave these guidelines as they are were based on a lack of evidence to justify the proposed changes, coupled with a reluctance to make revisions that would require major changes in worldwide educational practices without such evidence.Nonetheless, some major changes were made. The time-honored procedure ol pulse check by lay rescuers was eliminated altogether and replaced with an assessment for other signs of circulation. Likewise, it was recommended that even the professional rescuer now check for these other signs of circulation. Although professional rescuers may simultaneously check for a pulse, they should do so only for a short period of time (within 10 seconds). There was also enthusiasm for deleting the ventilation aspect of EMS dispatcher-assisted CPR instructions that are provided to rescuers at the scene who are inexperienced in CPR. lt was made clear, though, that the data are applicable only to adult patients who are receiving CPR and that the data are appropriate most for EMS systems with rapid response times.

    2009-01-01

    背景与目的 心搏骤停时,传统的胸外按压心肺复苏(CPR)方法 容易使1/3被救者发生肋骨骨折,不能保证CPR时进行标准力度和幅度的胸外按压,且此时胸廓复张受限,均使心泵和胸泵机制不能得到理想发挥,从而影响了复苏效果.近年来受到关注的腹部按压CPR方法 只能使膈肌自然回至原位,不能最大限度地增加膈肌移动幅度,难以保证有效的循环和呼吸.为此,我们发明设计一种新的CPR装置,即腹部提压CPR装置.方法 腹部提压CPR装置通过吸盘吸附于腹部,利用相连的手柄有节律地提拉和按压进行CPR.结果 该方法 在避免肋骨骨折等并发症发生的同时,充分利用了"心泵"和"胸泵"的作用,同时又能起到一定的通气作用.结论 腹部提压CPR装置是迄今为止CPR方法 的一次重大创新,将可能成为主流的CPR方法.%Background and Objective When cardiac arrest occurs, in about 1/3 patients may suffer from fracture of ribs as a result of the traditional method of cardiopulmonary resuscitation (CPR) with strong compression of the chest wall. Consequently, there would be a marked decrease in amplitude of chest compression and expansion, thus reducing the effect of CPR. Rhythmic abdominal compression, which is a new mothod recently recognized to be effective for CPR, only allows the diaphragm to fall back to its original position, therefore the extent of its movement is not enough to affect lung expansion. Thus, the maneuver could not restore effective heart beat and respiration. We have invented a new equipment which is called abdominal lifting and compression equipment for CPR. Methods The new equipment for CPR consists a sucking device to attach on the abdominal wall, and with a handle, the abdominal wall can be lifted and compressed rhymically to produce the effect of CPR. Results The method readily got rid of the defects of the conventional CPR such as the risk of rib fracture, and made full use of

    The American Heart Association and the European Resuscitation Council recently recommend-ed that vasopressin can be used for cardiopulmonary resuscitation, instead of epinephrine. However, the guidelines do not discuss the effects of vasopressin during cerebral resuscitation. In this study, we intraperitoneally injected epinephrine and/or vasopressin during cardiopul-monary resuscitation in a rat model of asphyxial cardiac arrest. The results demonstrated that, compared with epinephrine alone, the pathological damage to nerve cells was lessened, and the levels of c-Jun N-terminal kinase and p38 expression were signiifcantly decreased in the hippo-campus after treatment with vasopressin alone or the vasopressin and epinephrine combination. No signiifcant difference in resuscitation effects was detected between vasopressin alone and the vasopressin and epinephrine combination. These results suggest that vasopressin alone or the vasopressin and epinephrine combination suppress the activation of mitogen-activated protein kinase and c-Jun N-terminal kinase signaling pathways and reduce neuronal apoptosis during cardiopulmonary resuscitation.

    Cardiac and pulmonary diseases are primary causes of global morbidity and mortality. Since the prevalence of both cardiac and pulmonary diseases increases with age, cardiopulmonary comorbidities inflict especially the elderly. Due to the tight physiological connection of the heart and the lung, diseases of both organs affect each other beyond a mere coincidence. At the same time, due to the similarity of their respective symptoms, their differentiation is challenging in clinical practice and therefore, comorbidities can be easily overlooked. This article provides an overview on the characteristics of cardiopulmonary comorbidities and their specific-, but also mutual pathophysiology. PMID:26886042

    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.

    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.

    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.

    院外心脏性猝死(out of hospital cardiac arrest,OHCA)发生率高,但是OHCA患者的生存率却很低.对旁观者开展心肺复苏(CPR)培训是改善实际CPR质量、提高OHCA生存率的重要手段.CPR培训质量的评估包括即时的理论与技能掌握效果以及中长期的知识巩固程度.通过理论考核以及模拟人技能操作评估培训效果,评估指标包括反映CPR质量的大部分参数.不同的教学方法、方式及学员本身的因素(如年龄、性别、身体因素、动机与态度等)也会影响CPR的培训质量.希望通过端正学员学习动机,根据其自身特点综合运用各种教学辅助器材开展个性化的CPR教学,同时建立标准化的考评指标体系,定期进行重复更新训练,以此优化即时的教学效果,巩固中长期的技能掌握程度.%Lots of people experience out of hospilal cardiac arrest (OHCA) , but the survival rale from OHCA was very low. Byslander - initialed cardiopulmonary resuscilalion ( CPR) plays a major role in the " chain of survival" to save the OHCA, therefore, the quality of CPR training is very important. We assess the quality of CPR training that comprised the short - term effect and skill retention by theoretical examination and skill performance on the manikin. The quality of CPR training is affected by different education means or method and the students' factors themselves such as age, gender, motivation, attitude and so on. Improving students'motivation and attitude, personalized training and tutoring program, application all kinds of training auxiliary instrument, establishment of the standard assessment system and recurrent training can optimize the short - term teaching effectiveness and consolidatethe retention.

    Objective To investigate the efficiency and safety of the automated external defibrillator (AED); and to compare the defibrillating efficacy between the domestic AED and the imported AED. Method Fourteen Peking white swine weighed (30 ± 1 ) kg, were anaesthetized and arterial cannula was inserted into the left femoral artery for collecting blood samples and measuring artery blood pressure, cardiac output (CO) and external vascular lung water index (EVWI) by using PiCCO monitor, and another cannula was inserted into the left femoral vein to place an electrode as a temporary pace maker, and then ventricular fibrillation (VF) was induced by using a programmed electrical stimulation instrument. The swine were divided into two groups randomly ( random number) after VF was confirmed by electrocardio-monitor,and the domestic made AED (M group, n = 7) or imported AED (Z group, n = 7) were used respectively in 7 swine of each group. The electrodes of defibrillator were stuck to the precordium and sternum separately, and defibrillation was delivered by the AED signal. The entire procedure of defibrillation was repeated four times. The number of defibrillation delivery required to get normal cardiac rhythm was recorded. Twenty minutes after restoration of spontaneous circulation (ROSC), blood sample was taken to measure myocardial enzyme. The CO and EVWI were measured too. Measurement data was analyzed by repeated ANOVA and enumeration data was analyzed by Chi-square test. A value of P <0.05 was regarded as being significant statistical difference. Results There were 54 episodes of VF induced in 14 swine and only one swine in Z group was dead after 2nd episode of VF, resulting in 98.1% success rate of resuscitation. There were 37 defibrillation deliveries given to swine of M group, and 75.0% produced normal cardiac rhythm after the first delivery of defibrillation,whereas 80.0% in Z group after 32 defibrillation deliveries. The length of time from AED turned on to the

    Children have unique physiologic, physical, psychological, and social needs compared with adults. Although adhering to the basic tenets of burn resuscitation, resuscitation of the burned child should be modified based on the child's age, physiology, and response to injury. This article outlines the unique characteristics of burned children and describes the fundamental principles of pediatric burn resuscitation in terms of airway, circulatory, neurologic, and cutaneous injury management.

    More than 4 decades after the creation of the Brooke and Parkland formulas, burn practitioners still argue about which formula is the best. So it is no surprise that there is no consensus about how to resuscitate a thermally injured patient with a significant comorbidity such as heart failure or cirrhosis or how to resuscitate a patient after an electrical or inhalation injury or a patient whose resuscitation is complicated by renal failure. All of these scenarios share a common theme in that the standard rule book does not apply. All will require highly individualized resuscitations. PMID:27600129

    Objective To investigate the changes of the expression of HIF-1α (hypoxia induciblefactor-1a) mRNA in myocardium of rats after cardiopulmonary resuscitation (CPR) and the intervention effects of exogenous hydrogen sulfide on it. Method Forty five male SD rats were randomly divided into three groups: control group ( n = 15 ), cardiopulmonary resuscitation group ( CPR group, n = 15 ) and NaHS + CPR group (n = 15 ) . Rats of control group were anesthetized and intubated without asphyxia and cardiac arrest. The rats of CPR group and NaHS + CPR group were operated to induce cardiac arrest by asphyxiation. In the rats of NaHS + CPR group, NaHS in dose of 50 ug/kg was administrated via the femoral venous line 1 minute before CPR. Hemodynamic was monitored continuously. The expression of HIF - lα mRNA in myocardium of rats in each group was determined by using RT-PCR and the activity of myeloperoxidase (MPO) in the myocardium of rats in each group was assayed by using a patent reagent box 6 h after CPR. The histopathological changes of myocardium were also observed. The t- test was used for statistical analysis. Results There was no statistically significant difference in hemodynamic changes between CPR group and CPR + NaHS group ( P > 0. 05 ) . When compared with the control group, the activity of MPO and the expression of HIF-1α mRNA in CPR group and CPR + NaHS group were both increased, and those increased in CPR + NaHS group was more significant (P < 0. 05) . When compared with CPR group, the expression of HIF-1α mRNA in CPR + NaHS group was higher, however, the activity of MPO in CPR + NaHS group was lower ( P < 0. 05) . There were various histopathological changes of myocardium of rats found in CPR group and CPR + NaHS group, and the damage of myocardium of rats in CPR group was more obvious than that in CPR + NaHS group. Conclusions The expression of HIF-1α mRNA in myocardium of rats was increased after CPR. Exogenous hydrogen sulfide can protect

    Objective To compare the hemodynamic effect of standard-cardiopulmonary resuscitation (S-CPR) and of CPR by cardiac massage under the diaphragmatic muscle (D-CPR), and to evaluate the feasibility of D-CPR. Methods Twenty healthy New Zealand rabbits were randomly divided into two groups, one group receiving S-CPR (n= 10) and the other group receiving D-CPR (n=10). Cardiac arrest was induced by asphyxiation at the end expiration for 8 minutes. After the hemodynamic situation was stable for 5 minutes before asphyxiation, the readings of ascending aorta systolic pressure (AOS) and diastolic pressure (AOD), transcutaneous oxygen saturation (SpO2), right atrial systolic pressure (RASP), right atrial diastolic pressure (RADP), and electrocardiogram were recorded consecutively to the end of the experiment. The mean arterial pressure (MAP) of ascending aorta and coronary perfusion pressure (CPP) were calculated, The rate of restoration of spontaneous circulation (ROSC) and the survival rate in a short duration of 6 hours were observed. Results Five rabbits in S-CPR group and 8 in D-CPR group were successfully resuscitated and obtained ROSC (50%, 80%, P=20. 05). Six hours survival rate was 400% in S-CRP group and 500% in D-CPR group. The comparisons between the two groups on AOS, AOD, MAP and CPP respectively showed that at 1 minute and 5 minutes during resuscitation the respective variables were higher in the D-CPR group than that in the S-CPR group (all P<0. 05). Compared to the bemodynamics before asphyxiation, the MAP and CPP in the D-CPR group increased 54. 1% and 33.4% of basic value at 1 minute, and they were 60. 0% and 41.8% at 5 minutes, while the AOS and AOD in the S-CPR group only increased by an average of 37. 3% and 16.5% at 1 minute, and they were 38. 5% and 17. 1% at 5 minutes, respectively. After ROSC, the hemodynamic variations of the D-CPR rabbits were more stable than those of S-CPR rabbits. Conclusion D-CPR can provide higher arterial pressure, cardiac

    We report the case of successful resuscitation after prolonged cardiac arrest during orthotopic liver transplantation. After reperfusion, the patient developed ventricular tachycardia, complicated by intracardiac clot formation and massive hemorrhage. Transesophageal echocardiography demonstrated stunned and nonfunctioning right and left ventricles, with developing intracardiac clots. Treatment with heparin, massive transfusion and prolonged cardiopulmonary resuscitation ensued for 51 minutes. Serial arterial blood gases demonstrated adequate oxygenation and ventilation during cardiopulmonary resuscitation. Cardiothoracic surgery was consulted for potential use of extracorporeal membrane oxygenation, however, the myocardial function improved and the surgery was completed without further intervention. On postoperative day 6, the patient was extubated without neurologic or cardiac impairment. The patient continues to do well 2 years posttransplant, able to perform independent daily activities of living and his previous job. This case underscores the potential for positive outcomes with profoundly prolonged, effective advanced cardiovascular life support in patients who experience postreperfusion syndrome. PMID:27233818

    Objective To explore the effects of beta-amyloid precursor protein (APP17) peptide on the changes in the expressions of phosphoinositide 3-kinase(PI3K), protein kinase B(PKB) and phosphorylation of cAMP response element binding protein (p-CREB) in the neurons of hippocampal gyms in rats after cardiopulmonary resuscitation. Method Twenty-one Wistar rats were randomly divided into three groups, namely the sham-operated control group, the resuscitation group and resuscitation with APP17 peptide-treated group. The rat model of asphyxial cardiac arrest was made by clamping the endotracheal tube and the standard external cardiopulmonary resuscitation ( CPR) was performed until the restoration of spontaneous circulation ( ROSC) observed.ROSC was defined by the appearance of normal QRS waves of electrocardiogram and mean artery pressure ( MAP)≥60 mmHg for more than 10 minutes. Rats of resuscitation group and control group received intravenous 0.9%NaCl, and the rats of the APP17 peptide group were treated with APP17 peptide(10μg·300 g~(-1), i. v.) after ROSC. Rats were sacrificed by decapitation after reperfusion 2 hours and then the cerebral hippocampal gyrus was immediately separated to detect PI3K, PKB and p-CREB by immunohistochemistry ( IHC) and Western-blot analysis. Statistical comparisons were made by one-way analysis of variance (ANOVA) . Results IHC showed that there was no significant difference in PDK positive cells between resuscitation group and control group (2.75 ±1.80 vs. 2.53 ± 1.53, P > 0.05) . The PDK obviously more increased in the APP17 peptide group than in resuscitation group(5.85 ± 2.83 vs. 2.75 ± 1.80, P < 0.01) .The counts of PKB and p-CREB positive cells were obviously lower in resuscitation group than those in control group (2.45 ± 1.36 vs. 5.22 ± 2.50, P < 0.05);(2.41 ± 1.11 vs. 8.31 ±3.02, P < 0.01 ). The PKB and p-CREB positive cells were significantly higher in the APP17 peptide group than in resuscitation group (9.66±4.32 vs. 2

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

    2010-01-01

    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

    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.

    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

    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

    Enhanced measures for resuscitation of adults are based on basic measures of resuscitation. The central elements are highly effective chest compressions and avoidance of disruptions that are associated with poor patient outcomes that occur within seconds. The universal algorithm distinguishes the therapy for ventricular fibrillation from the therapy in asystole or pulseless electrical activity (PEA) by the need of defibrillation, and amiodarone administration in the former. Defibrillation is biphasic. In all other aspects, there are no differences in therapy. In each episode of cardiac arrest, reversible causes should be excluded or treated. For the diagnosis during resuscitation, sonography can be helpful. What is new in the 2015 ERC recommendations is the use of capnography, which can be used for the assessment of ROSC (return of spontaneous circulation), ventilation, resuscitation and intubation quality. Mechanical resuscitation devices can be used in selected situations. Successful primary resuscitation should be directly followed by measures of the post-resuscitation care. PMID:27022698

  12. Witnessed resuscitation: a concept analysis.

    Science.gov (United States)

    Walker, Wendy Marina

    2006-03-01

    The science and practice of resuscitation is recognised and endorsed on an international level, yet for more than a decade it has appeared in the literature alongside words such as witnessing or witnessed to signify the practice of family presence during a resuscitation attempt. This paper explores the meaning of witnessed resuscitation using the process for concept analysis proposed by Rodgers. The term resuscitation is explored, followed by identification of relevant uses of the concept of witnessed resuscitation. The reader is introduced to conceptual variations that challenge the way in which the concept has become associated with family or relatives presence in the resuscitation room of an accident and emergency department. Conceptual clarity is further enhanced through the identification of references, antecedents and consequences of witnessed resuscitation and by providing a model case of the concept that includes its defining attributes.

    2016-01-01

    Hemorrhagic shock is a principal cause of death among trauma patients within the first 24 hours after injury. Optimal fluid resuscitation strategies have been examined for nearly a century, more recently with several randomized controlled trials. Hypotensive resuscitation, also called permissive hypotension, is a resuscitation strategy that uses limited fluids and blood products during the early stages of treatment for hemorrhagic shock. A lower-than-normal blood pressure is maintained until operative control of the bleeding can occur. The randomized controlled trials examining restricted fluid resuscitation have demonstrated that aggressive fluid resuscitation in the prehospital and hospital setting leads to more complications than hypotensive resuscitation, with disparate findings on the survival benefit. Since the populations studied in each randomized controlled trial are slightly different, as is the timing of intervention and targeted vitals, there is still a need for a large, multicenter trial that can examine the benefit of hypotensive resuscitation in both blunt and penetrating trauma patients.

    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). Flow cytometry(FCM)was used to detect the neurocyte apoptotic rate. Results Compared between normal control and sham operation groups,there were no significant differences in the expression of apoptosis-related miRNA and neurocyte apoptosis rate of cerebral cortex(both P>0.05). Compared with sham operation group,in CA-CPR group, 16 miRNA expressions were up-regulated,including Let-7c,miR-15a,miR-21,miR-24,miR-29,miR-29b, miR-34a, miR-103, miR-200a, miR-200b, miR-200c, miR-210, miR-326, miR-338-3p, miR-494 and miR-497,and there were 22 down-regulated,being Let-7a,Let-7b,Let-7d,Let-7e,miR-19a,miR-19b-1, miR-20a,miR-20b,miR-23a,miR-23b,miR-25,miR-98,miR-107,miR-122a,miR-125a,miR-125b, miR-145,miR-181a,miR-181c,miR-335,miR-384-5p and miR-422a. Eight miRNA had significant changes at 24 hours after ROSC,in which miR-15a,miR-21,miR-34a,miR-497 were up-regulated respectively for 6.831±2.625,8.122±3.442,5.349±2.010,6.590±3

    Anaphylactoid reactions to iodinated contrast media can cause life-threatening events and even death. A 44-year-old woman presented with cardiopulmonary arrest (CPA) immediately following the administration of nonionic iodinated contrast media for an intravenous pyelography. Her cardiac rhythm during CPA was asystole. She was successfully resuscitated by the radiologists supported by paged emergency physicians using the prompt intravenous administration of 1 mg of epinephrine. Neither laryngeal edema nor bronchial spasm was observed during the course of treatment, and she was discharged on the 4th day without any complications. The patient did not have a history of allergy, but had experienced a myocardial infarction and aortitis. She had undergone 11 angiographies and had been taking a beta-adrenergic receptor antagonist. Planned emergency medical backup is advisable to ensure resuscitation in the event of an anaphylactoid reaction to the use of contrast media in-hospital settings. PMID:12009227

    Objective To investigate the effect on electrical restitution of β1-adrenergic receptor antagonist esmolol administered during cardiopulmonary resuscitation in the porcine ventricular fibrillation model. Method Ventricular fibrillation untreated for four minutes was induced by dynamic steady state pacing protocol in 40 healthy male pigs, in which local unipolar electrograms were recorded using one 10-electrode catheter that was sutured to the left ventrieular epicarditan. During CPR, animals were randomized into two groups to receive saline as placebo or esmolol after two standards doses of epinephrine. At postresuscitation 2-hour, six pigs were randomly selected from each group and the second VF induction was performed. Local activation-recovery intervals (ARI) restitutions and the VF inducibility between control group and esmolol group were compared. Western blotting was performed to determine cardiac ryanodine receptor (RyR2) protein expression, and their phosphorylation status. Results No sig-nificant differences were observed at the restoration of spontaneous circulation between two groups. Higher postre-suseitation 2-hour survival rate was observed in the esmolol group. Esmolol significantly flattened ARI restitution slope, lessened regional difference of ARI restitution, decreased the VF inducibility, and alleviated RyR2 hyper-phosphorylation. Conclusions Esmolol given during CPR significantly improved postresuscitation 2-hour survival rate. Its effects on modulating electrical restitution property and intracellular calcium handling make up the most important reasons why β1-blockade significantly reduced the onset and maintenance of VF.%目的 探讨在心室颤动心肺复苏模型中联合应用肾上腺素和艾司洛尔对心肌动作电位恢复性质的影响,了解β1-肾上腺素能受体拈抗剂艾司洛尔防治室颤的潜在机制.方法 稳定动态刺激健康雄性大Yorkshire猪发生心室颤动,心外膜接

  18. Fluid resuscitation in trauma

    2006-01-01

    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.

    Science.gov (United States)

    Cancio, Leopoldo C; Salinas, Jose; Kramer, George C

    2016-10-01

    Fluid resuscitation of burn patients is commonly initiated using modified Brooke or Parkland formula. The fluid infusion rate is titrated up or down hourly to maintain adequate urine output and other endpoints. Over-resuscitation leads to morbid complications. Adherence to paper-based protocols, flow sheets, and clinical practice guidelines is associated with decreased fluid resuscitation volumes and complications. Computerized tools assist providers. Although completely autonomous closed-loop control of resuscitation has been demonstrated in animal models of burn shock, the major advantages of open-loop and decision-support systems are identifying trends, enhancing situational awareness, and encouraging burn team communication.

    The cardiopathic patient can sustain acute heart failure during pregnancy. In such cases, if open heart operation is necessary to save the patient's life, the fetus could be seriously compromised after exposure to cardiopulmonary bypass. From 1958 to 1992, 69 reports of cardiac operations during pregnancy with the aid of cardiopulmonary bypass have been published. Maternal mortality was 2.9%. Embryofetal mortality was 20.2%. Examining only the last 40 patients, maternal and embryofetal mortality were 0.0% and 12.5%, respectively. Embryofetal mortality was 24.0% when hypothermia was used, compared with 0.0% while operating in normothermia. Maternal mortality did not change. The use of hypothermia during cardiopulmonary bypass provoked uterine contractions in several patients. Hypothermia decreases O2 exchange through the placenta. Pump flow and mean arterial pressure during cardiopulmonary bypass seem to be the most important parameters that influence fetal oxygenation. We speculate that cardiac operation is not a contraindication to pregnancy prolongation. PMID:8561577

    Life sciences research in the cardiopulmonary discipline must identify possible consequences of space flight on the cardiopulmonary system, understand the mechanisms of these effects, and develop effective and operationally practical countermeasures to protect crewmembers inflight and upon return to a gravitational environment. The long-range goal of the NASA Cardiopulmonary Discipline Research Program is to foster research to better understand the acute and long-term cardiovascular and pulmonary adaptation to space and to develop physiological countermeasures to ensure crew health in space and on return to Earth. The purpose of this Discipline Plan is to provide a conceptual strategy for NASA's Life Sciences Division research and development activities in the comprehensive area of cardiopulmonary sciences. It covers the significant research areas critical to NASA's programmatic requirements for the Extended-Duration Orbiter, Space Station Freedom, and exploration mission science activities. These science activities include ground-based and flight; basic, applied, and operational; and animal and human research and development. This document summarizes the current status of the program, outlines available knowledge, establishes goals and objectives, identifies science priorities, and defines critical questions in the subdiscipline areas of both cardiovascular and pulmonary function. It contains a general plan that will be used by both NASA Headquarters Program Offices and the field centers to review and plan basic, applied, and operational (intramural and extramural) research and development activities in this area.

    As trauma systems develop, more patients can potentially benefit from immediate surgery. With in-house surgeons available, enthusiasm for direct transfer from the scene to the operating room (OR) has developed in many institutions. The purpose of this study was to define precisely which patients should be taken to the OR for resuscitation. Three hundred twenty-three patients were taken to the OR directly from the field during a 4-year period (6.9% of trauma activations). Indications included the following: (1) cardiac arrest--one vital sign present, (2) persistent hypotension despite field intravenous fluid, and (3) uncontrolled external hemorrhage. A board-certified surgeon and resuscitation team met the field transport team in the OR in all cases. Cardiopulmonary resuscitation for patients with blunt trauma was not accompanied by survival even with immediate surgery by a trained surgeon and it wastes valuable OR resources. Patients with prehospital hypotension unresponsive to fluid resuscitation indicate the need for rapid surgery. Patients with blunt injuries even with hypotension infrequently undergo operations in less than 20 minutes and can be resuscitated in traditional areas where better roentgenograms are obtained. Penetrating injuries to the chest and abdomen with hypotension are the primary indications for OR resuscitation. It can be anticipated with field communication and accompanied by enhanced survival.

    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.

    Since the 1940s, the resuscitation of burn patients has evolved with dramatic improvements in mortality. The most significant achievement remains the creation and adoption of formulae to calculate estimated fluid requirements to guide resuscitation. Modalities to attenuate the hypermetabolic phase of injury include pharmacologic agents, early enteral nutrition, and the aggressive approach of early excision of large injuries. Recent investigations into the genomic response to severe burns and the application of computer-based decision support tools will likely guide future resuscitation, with the goal of further reducing mortality and morbidity, and improving functional and quality of life outcomes.

    Various diseases often result in decompensation requiring resuscitation. In infants moderate hypoxia evokes a compensatory augmented breath – sigh and more severe hypoxia results in a solitary gasp. Progressive asphyxia provokes gasping respiration saving the healthy infant – autoresuscitation by gasping. A neonate with sudden infant death syndrome, however, usually will not survive. Our systematic research in animals indicated that airway reflexes have similar resuscitation potential as gasp...

  12. Thrombin during cardiopulmonary bypass.

    Science.gov (United States)

    Edmunds, L Henry; Colman, Robert W

    2006-12-01

    Cardiopulmonary bypass (CPB) ignites a massive defense reaction that stimulates all blood cells and five plasma protein systems to produce a myriad of vasoactive and cytotoxic substances, cell-signaling molecules, and upregulated cellular receptors. Thrombin is the key enzyme in the thrombotic portion of the defense reaction and is only partially suppressed by heparin. During CPB, thrombin is produced by both extrinsic and intrinsic coagulation pathways and activated platelets. The routine use of a cell saver and the eventual introduction of direct thrombin inhibitors now offer the possibility of completely suppressing thrombin production and fibrinolysis during cardiac surgery with CPB.

    Giving family members the option of being present during resuscitation has been shown to be beneficial for both family and staff. However, only a small percentage of intensive care units have policies promoting family-witnessed resuscitation. This article reviews current research showing the benefits of family-witnessed resuscitation, outlines how to successfully integrate a family facilitator during resuscitation, and includes research that has been effective in changing the prevailing attitudes of staff. The authors also argue for the resuscitation team to practice ethical and cultural humility when involving family members so that all resuscitation efforts are a success, whether the patient lives or dies.

    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.

    that, for every minute delayed on defibrillating a heart arrest patient, survival chances decrease by 10%, and that the same chances of survival are 98% effective when it is employed within 30 seconds. 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.

    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.

    The inflammatory state after burn injury is characterized by an increase in capillary permeability that results in protein and fluid leakage into the interstitial space, increasing resuscitative requirements. Although the mechanisms underlying increased capillary permeability are complex, damage from reactive oxygen species plays a major role and has been successfully attenuated with antioxidant therapy in several disease processes. However, the utility of antioxidants in burn treatment remains unclear. Vitamin C is a promising antioxidant candidate that has been examined in burn resuscitation studies and shows efficacy in reducing the fluid requirements in the acute phase after burn injury.

    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.

    Intravenous (IV) cannulation and sterile IV salt solutions may not be options in resource-limited settings (RLSs). This article presents recipes for fluid resuscitation in the aftermath of burns occurring in RLSs. Burns of 20% total body surface area (TBSA) can be resuscitated, and burns up to 40% TBSA can most likely be resuscitated, using oral resuscitation solutions (ORSs) with salt supplementation. Without IV therapy, fluid resuscitation for larger burns may only be possible with ORSs. Published global experience is limited, and the magnitude of burn injuries that successfully respond to World Health Organization ORSs is not well-described. PMID:27600127

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.

  6. Statins for post resuscitation syndrome.

    After sudden cardiac arrest, successful resuscitation and return of spontaneous circulation, a multi-faceted ischaemia/reperfusion related disorder develops. This condition now known as post resuscitation syndrome is characterised by marked increases in the inflammatory response and changes in coagulation profile and vascular reactivity. Additionally, the production of reactive oxygen species and activation of cytotoxic cascades of metabolism add to these injury mechanisms resulting in multiorgan perfusion deficits and dysfunction. Especially in the cerebrum these injuries may be the cause of significant morbidity and mortality. Recent evidence has shown that statins (3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors) exert numerous beneficial effects in cardiovascular diseases irrespective of the lipid status. Remarkably, these pleiotropic effects seem to extended beyond cardiovascular diseases such as immunomodulative and antioxidative properties. We hypothesised that administration of statins early in the post resuscitation phase would prove beneficial in the resuscitated patient via several pleiotropic effects. These include inhibition of excessive coagulation and inflammatory response, suppression of oxygen radical production and improved vascular reactivity. The discussed effects are mediated via multiple pathways activated in the cardiac arrest victim, to which statins have been shown to have a beneficial modulating effect in experimental settings and non-cardiac arrest patients. To test this hypothesis in clinical practice, a randomized, controlled trial with sufficient power and standardised post resuscitation treatment would be necessary. The generally good tolerance of statin therapy with minimal adverse effects would support this experiment, although a parenteral form of the drug to ensure adequate dosage might be a prerequisite.

    The lung is profoundly affected by gravity. The absence of gravity (microgravity) removes the mechanical stresses acting on the lung paranchyma itself, resulting in a reduction in the deformation of the lung due to its own weight, and consequently altering the distribution of fresh gas ventilation within the lung. There are also changes in the mechanical forces acting on the rib cage and abdomen, which alters the manner in which the lung expands. The other way in which microgravity affects the lung is through the removal of the gravitationally induced hydrostatic gradients in vascular pressures, both within the lung itself, and within the entire body. The abolition of a pressure gradient within the pulmonary circulation would be expected to result in a greater degree of uniformity of blood flow within the lung, while the removal of the hydrostatic gradient within the body should result in an increase in venous return and intra-thoracic blood volume, with attendant changes in cardiac output, stroke volume, and pulmonary diffusing capacity. During the 9 day flight of Spacelab Life Sciences-1 (SLS-1) we collected pulmonary function test data on the crew of the mission. We compared the results obtained in microgravity with those obtained on the ground in both the standing and supine positions, preflight and in the week immediately following the mission. A number of the tests in the package were aimed at studying the anticipated changes in cardiopulmonary function, and we report those in this communication.

    In order to study the occurrence of postbypass hyperamylasemia, 75 patients undergoing cardiopulmonary bypass (CPB) were studied from March 1989 to January 1990. There were 49 males and 26 females. Among them, 27 had congenital heart disease, 30 had valvular disease, and 18 had coronary artery disease. There were 27 patients with at least one elevated serum amylase sample after operation. Thus, the overall incidence of hyperamylasemia was 36%. As compared with the preoperative data (1.3%), there was a statistically significant difference in the occurrence of hyperamylasemia (p less than 0.05). Three patients had overt clinical pancreatitis postoperatively. There was no positive correlation between the serum amylase level and the occurrence of pancreatitis (p greater than 0.05). Forty-two cases had a significant elevation of the amylase creatinine clearance ratio (ACCR) after CPB. However, there was no significant difference between the groups with pulsatile and nonpulsatile CPB (p greater than 0.05). Three patients (4%) died in our series. The causes of death were heart failure in two and fulminant pancreatitis associated with low cardiac output in one. Although our experience in dealing with pancreatitis improved survival, mortality was still high (33.3%) in our series. Nevertheless, there was no apparent correlation between mortality and postbypass hyperamylasemia (p greater than 0.05). Logistic regression analysis was used to analyze the risk factors of the occurrence of hyperamylasemia, and the analysis revealed that patients with coronary artery disease were susceptible to postbypass hyperamylasemia. Our studies indicate that the use of total serum amylase or ACCR to monitor for the occurrence of pancreatitis in postbypass patients is inadequate.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:1377742

    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.

    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.

  11. Resuscitation of newborn in high risk deliveries

    International Nuclear Information System (INIS)

    High risk deliveries are usually associated with increased neonatal mortality and morbidity. Neonatal resuscitation can appreciably affect the outcome in these types of deliveries. Presence of personnel trained in basic neonatal resuscitation at the time of delivery can play an important role in reducing perinatal complications in neonates at risk. The study was carried out to evaluate the effects of newborn resuscitation on neonatal outcome in high risk deliveries. Methods: This descriptive case series was carried out at the Department of Obstetrics and Gynecology, Jinnah Hospital, Lahore. Ninety consecutive high risk deliveries were included and attended by paediatricians trained in newborn resuscitation. Babies delivered by elective Caesarean section, normal spontaneous vaginal deliveries and still births were excluded. Neonatal resuscitation was performed in babies who failed to initiate breathing in the first minute after birth. Data was analyzed using SPSS-16.0. Results: A total of 90 high risk deliveries were included in the study. Emergency caesarean section was the mode of delivery in 94.4% (n=85) cases and spontaneous vaginal delivery in 5.6% (n=5). Preterm pregnancy was the major high risk factor. Newborn resuscitation was required in 37.8% (n=34) of all high risk deliveries (p=0.013). All the new-borns who required resuscitation survived. Conclusion: New-born resuscitation is required in high risk pregnancies and personnel trained in newborn resuscitation should be available at the time of delivery. (author)

    Almost one quarter of newborn deaths are attributed to birth asphyxia. Systematic implementation of newborn resuscitation programs has the potential to avert many of these deaths as basic resuscitative measures alone can reduce neonatal mortality. Simplified resuscitation training provided through Helping Babies Breathe decreases early neonatal mortality and stillbirth. However, challenges remain in providing every newborn the needed care at birth. Barriers include ineffective educational systems and programming; inadequate equipment, personnel and data monitoring; and limited political and social support to improve care. Further progress calls for renewed commitments to closing gaps in the quality of newborn resuscitative care. PMID:27524455

  14. 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

    Bokeriya, L.A.; Sokolova, N.A.; Konikova, A.S.

    At the present time, improvement of the system of medical care of cosmonauts is an important problem. For this reason, there are plans for development of a set of resuscitation measures that would be necessary in the case of onset of acute hypoxic and anoxic states, which may occur in sudden emergency situations. The purpose of the experiment was to examine the mechanism of transition from life to death on the molecular level. Renewal of proteins and nucleic acids, and change in their conformation (spatial arrangement) were used as the main indicators of changes in metabolic processes in case of death due to anoxic anoxia (exsanguination). With this procedure it was possible to reflect some patterns of biopolymer conversions related to processes of dying and resuscitation. Processes examined were the intensity of synthesis and dissociation of proteins and nucleic acids in the basic organs and tissues of experimental animals: different parts of the brain, myocardium and skeletal muscles, liver, kidneys, lung, spleen, adrenals, thyroid and pancreas, blood, bile and urine.

    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

    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.

    2014-01-01

    Full Text Available Current automated external defibrillators mandate interruptions of chest compression to avoid the effect of artifacts produced by CPR for reliable rhythm analyses. But even seconds of interruption of chest compression during CPR adversely affects the rate of restoration of spontaneous circulation and survival. Numerous digital signal processing techniques have been developed to remove the artifacts or interpret the corrupted ECG with promising result, but the performance is still inadequate, especially for nonshockable rhythms. In the present study, we suppressed the CPR artifacts with an enhanced adaptive filtering method. The performance of the method was evaluated by comparing the sensitivity and specificity for shockable rhythm detection before and after filtering the CPR corrupted ECG signals. The dataset comprised 283 segments of shockable and 280 segments of nonshockable ECG signals during CPR recorded from 22 adult pigs that experienced prolonged cardiac arrest. For the unfiltered signals, the sensitivity and specificity were 99.3% and 46.8%, respectively. After filtering, a sensitivity of 93.3% and a specificity of 96.0% were achieved. This animal trial demonstrated that the enhanced adaptive filtering method could significantly improve the detection of nonshockable rhythms without compromising the ability to detect a shockable rhythm during uninterrupted CPR.

    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 is critical for saving lives.Based on the experience of our team,we consider prompt exploratory laparotomy,irrespective of the results of the diagnostic tests,is the only way to provide objective assessment and adequate treatment,leading to dramatic reduction in the mortality rate.

  11. Cardiopulmonary Bypass and Oxidative Stress

    Directory of Open Access Journals (Sweden)

    Mustafa Zakkar

    2015-01-01

    Full Text Available The development of the cardiopulmonary bypass (CPB revolutionized cardiac surgery and contributed immensely to improved patients outcomes. CPB is associated with the activation of different coagulation, proinflammatory, survival cascades and altered redox state. Haemolysis, ischaemia, and perfusion injury and neutrophils activation during CPB play a pivotal role in oxidative stress and the associated activation of proinflammatory and proapoptotic signalling pathways which can affect the function and recovery of multiple organs such as the myocardium, lungs, and kidneys and influence clinical outcomes. The administration of agents with antioxidant properties during surgery either intravenously or in the cardioplegia solution may reduce ROS burst and oxidative stress during CPB. Alternatively, the use of modified circuits such as minibypass can modify both proinflammatory responses and oxidative stress.

    This review analyzes the literature dealing with cardiopulmonary function during and pulmonary function following laparoscopic cholecystectomy in order to describe the patterns of changes in these functions and the mechanisms involved as well as to identify areas of concern and lacunae in our knowledge. Information was obtained from a Medline literature search and the annual meeting supplements of Anesthesiology, Anesth Analg, Br J Anaesth, and Can J Anaesth. The principal findings were that changes in cardiovascular function due to the insufflation are characterized by an immediate decrease in cardiac index and an increase in mean arterial blood pressure and systemic vascular resistance. In the next few minutes there is partial restoration of cardiac index and resistance but blood pressure and heart rate do not change. The pattern is the result of the interaction between increased abdominal pressure, neurohumoral responses and absorbed CO2. Pulmonary function changes are characterized by reduced compliance without large alterations in PaO2, but tissue oxygenation can be adversely affected due to reduced O2 delivery. A major difficulty in maintaining normocarbia is due to the abdominal distention reducing pulmonary compliance and to CO2 absorption. End tidal CO2 tension is not a reliable index of PaCO2, particularly in ASA III-IV patients. The pattern of lung function following LC is characterized by a transient reduction in lung volumes and capacities with a restrictive breathing pattern and the loss of the abdominal contribution to breathing. Atelectasis also occurs. These changes are qualitatively similar to but of a lesser magnitude than those following "open" abdominal operations. It is concluded that the changes in cardiopulmonary function during laparoscopic upper abdominal surgery lead us to suggest judicious invasive monitoring and careful interpretation in ASA III-IV patients. Lung function following extensive procedures in sick patients has not been

    Background The choice of a defibrillation or a cardiopulmonary resuscitation (CPR)-first strategy in the treatment of prolonged cardiac arrest (CA) is still controversial.The purpose of this study was to compare the effects of defibrillation or CPR administered first on neurological prognostic markers in a porcine model of prolonged CA.Methods After 8 minutes of untreated ventricular fibrillation (VF),24 inbred Chinese Wuzhishan minipigs were randomized to receive either defibrillation first (ID group,n=12) or chest compression first (IC group,n=12).In the ID group,a shock was delivered immediately.If defibrillation failed to attain restoration of spontaneous circulation (ROSC),manual chest compressions were rapidly initiated at a rate of 100 compressions/min and a compression-to-ventilation ratio of 30:2.If VF persisted after five cycles of CPR,a second defibrillation attempt was made.In the IC group,chest compressions were delivered first,followed by a shock.After successful ROSC,hemodynamic status and blood samples were obtained at 0.5,1,2,4,6,and 24 hours after ROSC.Porcine-specific neuron-specific enolase (NSE) and S100B were measured from sera using enzyme-linked immunosorbent assays.Porcine cerebral performance category scores were used to evaluate preliminary neurological function following 24 hours recovery.Surviving pigs were sacrificed at 24 hours after ROSC and brains were removed for electron microscopy analysis.Results The number of shocks,total defibrillation energy,and time to ROSC were significantly lower in the ID group compared with the IC group.Compared with the IC group,S100B expression was decreased at 2 and 4 hours after ROSC,and NSE expression decreased at 6 and 24 hours after ROSC in the ID group.Brain tissue analysis showed that injury was attenuated in the ID group compared with the IC group.There were no significant differences between 6 and 24 hours survival rates.Conclusion Defibrillation first may result in a shorter time to ROSC and

    Hemorrhage is the second most common cause of death among trauma patients and almost half of the deaths occur within 24 hours after arrival.Damage control resuscitation is a new paradigm for patients with massive bleeding.It consists of permissive hypotension,hemostatic resuscitation and transfusion strategies,and damage control surgery.Permissive hypotension seems to have better results before the bleeding is controlled.The strategy of fluid resuscitation is minimizing crystalloid infusion and increasing early transfusion with a high ratio of fresh frozen plasma to packed red cells.Damage control surgery is done when the patient's condition is unfit for definitive surgery.Hemorrhage and contamination control with temporary abdominal closure is performed before transferring the patients to intensive care unit and the operating room for a permanent laparotomy.

    2006-01-01

    Full Text Available More than twenty-five years have elapsed since the first Do Not Resuscitate (DNR policies were proposed. A historical review of the application of DNR policies is provided with its rationale and perceived effects. A viewpoint is presented, that acceptance of implied consent for cardiopulmonary resuscitation (CPR in hospitalized patients was responsible for drawing up of DNR policies. Unfortunately, the principle of informed consent as related to CPR and DNR policies, has had unintended consequences. Practical results do not indicate that medical practices have become more humane. Abuses of the process go beyond matters of style and experience, in communicating with surrogate decision-makers. Instead of generating compassion and respect for the patient, policies may contribute to cynicism and lack of caring amongst physicians. Overly optimistic dependence on advance directives to reform medical practices, appears unjustified. The concept of futility to limit demands for non-beneficial care is examined. It is unlikely that physicians can routinely invoke futility, as an argument to limit treatments. A re-examination of DNR policies as a defense against technologic imperative is warranted.

    2014-01-01

    Full Text Available The optimal treatment of a severe hemodynamic instability from shock to cardiac arrest in late term pregnant women is subject to ongoing studies. However, there is an increasing evidence that early “separation” between the mother and the foetus may increase the restoration of the hemodynamic status and, in the cardiac arrest setting, it may raise the likelihood of a return of spontaneous circulation (ROSC in the mother. This treatment, called Perimortem Cesarean Section (PMCS, is now termed as Resuscitative Hysterotomy (RH to better address the issue of an early Cesarean section (C-section. This strategy is in contrast with the traditional treatment of cardiac arrest characterized by the maintenance of cardiopulmonary resuscitation (CPR maneuvers without any emergent surgical intervention. We report the case of a prehospital perimortem delivery by Caesarean (C section of a foetus at 36 weeks of gestation after the mother’s traumatic cardiac arrest. Despite the negative outcome of the mother, the choice of performing a RH seems to represent up to date the most appropriate intervention to improve the outcome in both mother and foetus.

    This study aimed to assess the effects of early fluid resuscitation (EFR) combined with high volume hemofiltration (HVHF) on the cardiopulmonary function and removal of inflammatory mediators in a septic shock swine model. Eighteen swine were randomized into three groups: control (n = 6) (extracorporeal circulating blood only), continuous renal replacement therapy (CRRT) (n = 6; ultrafiltration volume = 25 mL/Kg/h), and HVHF (n = 6; ultrafiltration volume = 85 mL/Kg/h). The septic shock model was established by intravenous infusion of lipopolysaccharides (50 µg/kg/h). Hemodynamic parameters (arterial pressure, heart rate, cardiac output, stroke volume variability, left ventricular contractility, systemic vascular resistance, and central venous pressure), vasoactive drug parameters (dose and time of norepinephrine and hourly fluid intake), pulmonary function (partial oxygen pressure and vascular permeability), and cytokines (interleukin-6 and interleukin-10) were observed. Treatment resulted in significant changes at 4-6 h. HVHF was beneficial, as shown by the dose of vasoactive drugs, fluid intake volume, left ventricular contractility index, and partial oxygen pressure. Both CRRT and HVHF groups showed improved removal of inflammatory mediators compared with controls. In conclusion, EFR combined with HVHF improved septic shock in this swine model. The combination decreased shock progression, reduced the need for vasoactive drugs, and alleviated the damage to cardiopulmonary functions.

    Full Text Available Introduction. Pulmonary embolism as a possible cause of acute heart failure is a potentially fatal condition that can cause death in all age groups. Patients successfully resuscitated after cardiac arrest have a high risk of increased mortality and their poor long­term outcome is often associated with severe neurological complications. Case Outline. This is a case report of a 67­year­old man after a successful cardiopulmonary resuscitation (CPR which was followed by therapeutic hypothermia (TH. The patient visited the dermatological outpatients’ department with clinical presentation of pain and swelling of the right leg, shortness of breath and chest pain. During examination the patient lost consciousness, stopped breathing and had cardiac arrest. ECG was done which registered asystole. We began CPR. After 59 minutes of resuscitation return of heartbeat was achieved. The patient was transported to the Emergency Department. On admission, after computerized tomography (CT of the chest confirmed massive pulmonary embolism (PE, the patient was administered thrombolytic therapy with Metalyse (tenecteplase and anti­coagulation therapy (heparin. After stabilization, therapeutic hypothermia was applied. Combination of EMCOOLSpad on the chest and abdomen and cold Ringer lactate 500 ml at 4°C was flushed. Temperature was decreased to 33°C and kept stabile for 24 hours. After eight days the patient was conscious with a minimal neurological deficit. Conclusion. As shown in this case report, and according to the rich experience elsewhere, cooling therapy after out­of­hospital cardiac arrest and successful CRP may be useful in preventing neurological complications.

    Background Hypoxic-ischemic brain injury (HIBI) after cardiopulmonary resuscitation is one of the most devastating neurological conditions that causing the impaired consciousness.However,there were few studies investigated the changes of brain metabolism in patients with vegetative state (VS) after post-resuscitated HIBI.This study aimed to analyze the change of overall brain metabolism and elucidated the brain area correlated with the level of consciousness (LOC) in patients with VS after post-resuscitated HIBI.Methods We consecutively enrolled 17 patients with VS after HIBI,who experienced cardiopulmonary resuscitation.Overall brain metabolism was measured by F-18 fluorodeoxyglucose positron emission tomography (F-18 FDG PET) and we compared regional brain metabolic patterns from t7 patients with those from 15 normal controls using voxel-by-voxel based statistical parametric mapping analysis.Additionally,we correlated the LOC measured by the JFK-coma recovery scale-revised of each patient with brain metabolism by covariance analysis.Results Compared with normal controls,the patients with VS after post-resuscitated HIBI revealed significantly decreased brain metabolism in bilateral precuneus,bilateral posterior cingulate gyrus,bilateral middle frontal gyri,bilateral superior parietal gyri,bilateral middle occipital gyri,bilateral precentral gyri (PFEw correctecd <0.0001),and increased brain metabolism in bilateral insula,bilateral cerebella,and the brainstem (PFEw correctecd <0.0001).In covariance analysis,the LOC was significantly correlated with brain metabolism in bilateral fusiform and superior temporal gyri (P uncorrected <0.005).Conclusions Our study demonstrated that the precuneus,the posterior cingulate area and the frontoparietal cortex,which is a component of neural correlate for consciousness,may be relevant structure for impaired consciousness in patient with VS after post-resuscitated HIBI.In post-resuscitated HIBI,measurement of brain

    Full Text Available Although emergency resuscitative thoracotomy is performed as a salvage maneuver for critical blunt trauma patients, evidence supporting superior effectiveness of emergency resuscitative thoracotomy compared to conventional closed-chest compressions remains insufficient. The objective of this study was to investigate whether emergency resuscitative thoracotomy at the emergency department or in the operating room was associated with favourable outcomes after blunt trauma and to compare its effectiveness with that of closed-chest compressions.This was a retrospective nationwide cohort study. Data were obtained from the Japan Trauma Data Bank for the period between 2004 and 2012. The primary and secondary outcomes were patient survival rates 24 h and 28 d after emergency department arrival. Statistical analyses were performed using multivariable generalized mixed-effects regression analysis. We adjusted for the effects of different hospitals by introducing random intercepts in regression analysis to account for the differential quality of emergency resuscitative thoracotomy at hospitals where patients in cardiac arrest were treated. Sensitivity analyses were performed using propensity score matching.In total, 1,377 consecutive, critical blunt trauma patients who received cardiopulmonary resuscitation in the emergency department or operating room were included in the study. Of these patients, 484 (35.1% underwent emergency resuscitative thoracotomy and 893 (64.9% received closed-chest compressions. Compared to closed-chest compressions, emergency resuscitative thoracotomy was associated with lower survival rate 24 h after emergency department arrival (4.5% vs. 17.5%, respectively, P < 0.001 and 28 d after arrival (1.2% vs. 6.0%, respectively, P < 0.001. Multivariable generalized mixed-effects regression analysis with and without a propensity score-matched dataset revealed that the odds ratio for an unfavorable survival rate after 24 h was lower for

    Morris, Richard W; Pybus, David A

    2007-12-01

    In this paper we describe a high-fidelity perfusion simulation system intended for use in the training and continuing education of perfusionists. The system comprises a hydraulic simulator, an electronic interface unit and a controlling computer with associated real-time computer models. It is designed for use within an actual operating theatre, or within a specialized simulation facility. The hydraulic simulator can be positioned on an operating table and physically connected to the circuit of the institutional heart-lung machine. The institutional monitoring system is used to display the arterial and central venous pressures, the ECG and the nasopharyngeal temperature using appropriate connections. The simulator is able to reproduce the full spectrum of normal and abnormal events that may present during the course of cardiopulmonary bypass. The system incorporates a sophisticated blood gas model that accurately predicts the behavior of a modern, hollow-fiber oxygenator. Output from this model is displayed in the manner of an in-line blood gas electrode and is updated every 500 msecs. The perfusionist is able to administer a wide variety of drugs during a simulation session including: vasoconstrictors (metaraminol, epinephrine and phenylephrine), a vasodilator (sodium nitroprusside), chronotropes (epinephrine and atropine), an inotrope (epinephrine) and modifiers of coagulation (heparin and protamine). Each drug has a pharmacokinetic profile based on a three-compartment model plus an effect compartment. The simulation system has potential roles in the skill training of perfusionists, the development of crisis management protocols, the certification and accreditation of perfusionists and the evaluation of new perfusion equipment and/or techniques.

    2016-09-01

    Although there are known detrimental effects of obesity on the heart and lungs, few data exist showing obesity as risk factor for cardiopulmonary disorders in dogs and cats. It is probable that increased abdominal fat is detrimental as it is in humans, and there is evidence of negative effects of increased intrathoracic fat. As well as physical effects of fat, increased inflammatory mediators and neurohormonal effects of obesity likely contribute to cardiopulmonary disorders. Weight loss in overweight individuals improves cardiac parameters and exercise tolerance. Obesity in patients with obstructive airway disorders is recognized to increase disease severity.

    To find out the optimal concentration, infusion rate and dosage of saline for resuscitation. Methods: Forty-five dogs were used to establish hypovolemic shock models. The dogs were resuscitated with saline of different concentrations and different dosages under different infusion rates, and the resuscitation results were compared. Results: The best concentration was 7.5%, the best rate of infusion 20 ml/min (a volume equivalent to 15% of the shed blood) and the best dosage 5.71 ml/kg. The method was effective for resuscitation, the mean arterial pressure (MAP) could be elevated to 89% of the baseline, and this MAP could be kept for more than one hour. Conclusions: Using 7.5% sodium chloride solution equivalent to 15% of the shed blood at an infusion rate of 20 ml/min can achieve a best resuscitation result.

    ObjectiveTo study the application of positron emission tomography (PET) in detection of myocardial metabolism in pig ventricular fibrillation and asphyxiation cardiac arrest models after resuscitation. MethodsThirty-two healthyminiature pigs were randomized into aventricular fibrillation cardiac arrest (VFCA) group (n=16) and an asphyxiation cardiac arrest (ACA)group (n=16). Cardiac arrest (CA) was induced byprogrammed electric stimulationorendotracheal tube clamping followed by cardiopulmonary resuscitation (CPR) anddefibrillation. At four hours and 24 h afterspontaneous circulation was achieved, myocardial metabolism was assessed by PET.18F-FDG myocardial uptake in PET was analyzed and the maximum standardized uptake value (SUVmax) was measured. ResultsSpontaneous circulation was 100% and 62.5% in VFCA group and ACA group, respectively.PET demonstrated that the myocardial metabolism injuries was more severe and widespread after ACA than after VFCA. The SUVmax was higher in VFCA group than in ACA group (P<0.01).In VFCA group,SUVmaxat 24h after spontaneous circulation increased to the level of baseline. ConclusionACA causes more severe cardiac metabolism injuries than VFCA. Myocardial dysfunction is associated with less successful resuscitation. Myocardial stunning does occur with VFCA but not with ACA.

    Full Text Available Pectus excavatum is a chest wall deformity that produces significant cardiopulmonary disability and is typically seen in younger patients. Minimally invasive repair of pectus excavatum or Nuss procedure has become a widely accepted technique for adult and pediatric patients. Although it is carried out through a thoracoscopic approach, the procedure is associated with a number of potential intraoperative and post-operative complications. We present a case of cardiac perforation requiring emergent cardiopulmonary bypass in a 29-year-old male with Marfan syndrome and previous mitral valve repair undergoing a Nuss procedure for pectus excavatum. This case illustrates the importance of vigilance and preparation by the surgeons, anesthesia providers as well as the institution to be prepared with resources to handle the possible complications. This includes available cardiac surgical backup, perfusionist support and adequate blood product availability.

    Full Text Available Clinically relevant animal models capable of simulating traumatic hemorrhagic shock are needed. We developed a hemorrhagic shock model with male New Zealand rabbits (2200-2800 g, 60-70 days old that simulates the pre-hospital and acute care of a penetrating trauma victim in an urban scenario using current resuscitation strategies. A laparotomy was performed to reproduce tissue trauma and an aortic injury was created using a standardized single puncture to the left side of the infrarenal aorta to induce hemorrhagic shock similar to a penetrating mechanism. A 15-min interval was used to simulate the arrival of pre-hospital care. Fluid resuscitation was then applied using two regimens: normotensive resuscitation to achieve baseline mean arterial blood pressure (MAP, 10 animals and hypotensive resuscitation at 60% of baseline MAP (10 animals. Another 10 animals were sham operated. The total time of the experiment was 85 min, reproducing scene, transport and emergency room times. Intra-abdominal blood loss was significantly greater in animals that underwent normotensive resuscitation compared to hypotensive resuscitation (17.1 ± 2.0 vs 8.0 ± 1.5 mL/kg. Antithrombin levels decreased significantly in normotensive resuscitated animals compared to baseline (102 ± 2.0 vs 59 ± 4.1%, sham (95 ± 2.8 vs 59 ± 4.1%, and hypotensive resuscitated animals (98 ± 7.8 vs 59 ± 4.1%. Evidence of re-bleeding was also noted in the normotensive resuscitation group. A hypotensive resuscitation regimen resulted in decreased blood loss in a clinically relevant small animal model capable of reproducing hemorrhagic shock caused by a penetrating mechanism.

    Objective: To study the changes between cerebral oxygen (O2) delivery and uptake in dogs resuscitated under normotension or hypertension for 4 h. Methods: The model of ventricular fibrillation of 8 min in 12 dogs was made,followed by open cardiopulmonary resuscitation, reperfnsion with normal or high mean arterial pressure (MAP), and controlled ventilation to 4 h. Animals were randomly assigned into Group NT (normotensive reperfusion, n = 6) and Group HT(hypertensive reperfusion, n = 6). Cerebral arteriovenous (sagittal sinus) O2 content difference (Ca-ssO2) and venous(sagittal sinus) PO2(PssO2) were determined before cardiac arrest (CA) and 30, 60, 120, and 240 min after CA. Results: In Group NT, Ca-ssO2 was lower at 30 min ( P < 0.05) but higher at 240 min ( P < 0.01 ) after CA than that before CA. In Group HT, Ca-ssO2 was not significantly different from that in Group NT before CA but was lower than that in Group NT at 30 min after CA ( P < 0.01 ). Ca-ssO2 was not significantly different in Group NT and HT thereafter. In both groups,PssO2 was both higher at 30 min after reperfnsion ( P < 0.01 ) and at 240 min after reperfnsion lower ( P < 0.05) than those before CA .At 30 min after reperfusion, PssO2 was higher (P<0.01) in Group HT than that in Group NT, with insignificant difference between two groups. Conclusion: Cerebral O2 delivery and uptake are mismatched after CA and resuscitation. Hypertensive reperfusion improves oxygen delivery to the brain early after CA.

    2012-02-01

    BACKGROUND: Advances in neonatal care continue to lower the limit of viability. Decision making in this grey zone remains a challenging process. OBJECTIVE: To explore the opinions of healthcare providers on resuscitation and outcome in the less than 28-week preterm newborn. DESIGN\\/METHODS: An anonymous postal questionnaire was sent to health care providers working in maternity units in the Republic of Ireland. Questions related to neonatal management of the extreme preterm infant, and estimated survival and long-term outcome. RESULTS: The response rate was 55% (74% obstetricians and 70% neonatologists). Less than 1% would advocate resuscitation at 22 weeks, 10% of health care providers advocate resuscitation at 23 weeks gestation, 80% of all health care providers would resuscitate at 24 weeks gestation. 20% of all health care providers would advocate cessation of resuscitation efforts on 22-25 weeks gestation at 5 min of age. 65% of Neonatologists and 54% trainees in Paediatrics would cease resuscitation at 10 min of age. Obstetricians were more pessimistic about survival and long term outcome in newborns delivered between 23 and 27 weeks when compared with neonatologists. This difference was also observed in trainees in paediatrics and obstetrics. CONCLUSION: Neonatologists, trainees in paediatrics and neonatal nurses are generally more optimistic about outcome than their counterparts in obstetrical care and this is reflected in a greater willingness to provide resuscitation efforts at the limits of viability.

    Full Text Available Introduction: The American Heart Association (AHA recommends regionalized care following out-of-hospital cardiac arrest (OHCA at cardiac resuscitation centers (CRCs. Key level 1 CRC criteria include 24/7 percutaneous coronary intervention (PCI capability, therapeutic hypothermia capability, and annual volume of ≥40 patients resuscitated from OHCA. Our objective was to characterize the availability and utilization of resources relevant to post-cardiac arrest care, including level 1 CRCs in California. Methods: We combined data from the AHA, the California Office of Statewide Health Planning and Development (OSHPD, and surveys to identify CRCs. We surveyed emergency department directors and nurse managers at all 24/7 PCI centers identified by the AHA to determine their post-OHCA care capabilities. The survey included questions regarding therapeutic hypothermia use and specialist availability and was pilot-tested prior to distribution. Cases of OHCA were identified in the 2011 OSHPD Patient Discharge Database using a “present on admission” diagnosis of cardiac arrest (ICD-9-CM code 427.5. We defined key level 1 CRC criteria as 24/7 PCI capability, therapeutic hypothermia, and annual volume ≥40 patients admitted with a “present on admission” diagnosis of cardiac arrest. Our primary outcome was the proportion of hospitals meeting these criteria. Descriptive statistics and 95% CI are presented. Results: Of the 333 acute care hospitals in California, 31 (9.3%, 95% CI 6.4-13% met level 1 CRC criteria. These hospitals treated 25% (1937/7780; 95% CI 24-26% of all admitted OHCA patients in California in 2011. Of the 125 hospitals identified as 24/7 PCI centers by the AHA, 54 (43%, 95% CI 34-52% admitted ≥40 patients following OHCA in 2011. Seventy (56%, 95% CI 47-65% responded to the survey; 69/70 (99%, 95% CI 92-100% reported having a therapeutic hypothermia protocol in effect by 2011.

    Endotracheal intubation to resuscitate neonates was used by Scheel in 1798. A century before endotracheal anesthesia was developed, inventive obstetricians constructed devices for endotracheal intubation of infants and mastered their insertion, localization, and airtight sealing. Fell's laryngoscope, Magill's intubation forceps and tissue-friendly materials were significant contributions of the 20th century to endotracheal intubation of the newborn. The striking absence of scientific studies on the most efficient resuscitation techniques for neonates can be explained by the difficulty to adjust for the personal skills of the resuscitator.

    Since October 1986, 6 hospital survivors who were salvaged from cardiopulmonary bypass (CPB) with the Sarns centrifugal pump were observed. Centrifugal assist was employed only after failure to wean with usual resuscitative measures, including multiple high dose inotropes and intraaortic balloon pumping. There were five men and one woman, 46-59 years of age (mean 61 years). All patients had undergone coronary artery bypass grafting, with two patients having had concomitant left ventricular aneurysmectomy and two aortic valve replacement. Five patients had left ventricular assist only and one had biventricular assist. Duration of assist ranged from 26 to 72 hr (mean 48 hr). Complications were ubiquitous, and the resultant prolonged hospitalization was resource intensive. All hospital survivors remain alive and are in New York Heart Association functional Class II, with an average follow-up of 24 months, (6-41 months). Compared with preoperative values, current left ventricular function is improved in 2 patients, has deteriorated in 3, and is unchanged in 1. Thus, the Sarns centrifugal pump will allow salvage of some patients who otherwise are not weanable from CPB. Survivors can expect a reasonable functional capacity as reflected by this experience.

In this paper, we describe the application of simulation in pediatric resuscitation training and review the evidence for the use of simulation in neonatal resuscitation, pediatric advanced life support, procedural skills training, and crisis resource management training. We also highlight studies supporting several key instructional design elements that enhance learning, including the use of high-fidelity simulation, distributed practice, deliberate practice, feedback, and debriefing. Simulation-based training is an effective modality for teaching pediatric resuscitation concepts. Current literature has revealed some research gaps in simulation-based education, which could indicate the direction for the future of pediatric resuscitation research.

  19. Assessing Exercise Limitation Using Cardiopulmonary Exercise Testing

    Directory of Open Access Journals (Sweden)

    Michael K. Stickland

    2012-01-01

    Full Text Available The cardiopulmonary exercise test (CPET is an important physiological investigation that can aid clinicians in their evaluation of exercise intolerance and dyspnea. Maximal oxygen consumption (V˙O2max is the gold-standard measure of aerobic fitness and is determined by the variables that define oxygen delivery in the Fick equation (V˙O2 = cardiac output × arterial-venous O2 content difference. In healthy subjects, of the variables involved in oxygen delivery, it is the limitations of the cardiovascular system that are most responsible for limiting exercise, as ventilation and gas exchange are sufficient to maintain arterial O2 content up to peak exercise. Patients with lung disease can develop a pulmonary limitation to exercise which can contribute to exercise intolerance and dyspnea. In these patients, ventilation may be insufficient for metabolic demand, as demonstrated by an inadequate breathing reserve, expiratory flow limitation, dynamic hyperinflation, and/or retention of arterial CO2. Lung disease patients can also develop gas exchange impairments with exercise as demonstrated by an increased alveolar-to-arterial O2 pressure difference. CPET testing data, when combined with other clinical/investigation studies, can provide the clinician with an objective method to evaluate cardiopulmonary physiology and determination of exercise intolerance.

    The management of trauma-related coagulopathy and haemorrhage is changing from a reactive strategy to a proactive early intervention with blood products and haemostatic agents. Although major haemorrhage and massive transfusion are associated with higher mortality, the pattern of this association with modern trauma care is poorly described. In addition, early predictors of massive transfusion, which might trigger a proactive haemostatic resuscitation strategy, are not currently available. We review recent literature relating to predictors of massive transfusions and the relationship between transfusion and mortality. PMID:21371347

    The need for a portable extracorporeal support system that can be rapidly initiated for various types of cardiopulmonary failure is well known. The authors report on a system consisting of 3/8 inch tubing, a Sci-Med membrane oxygenator, Omnitherm heat exchanger, Biomedicus or Sarns centrifugal pump, portable battery, and oxygen tanks. The system is mounted on a cart for easy mobility and can be primed in 5-10 min. USCI, DLP, or Axiom cannulas can be inserted femorally. Over 30 months, 29 patients, aged 19-78 years, underwent extracorporeal membrane oxygenation (ECMO) support for cardiac arrest during catheterization (10 patients), shock secondary to acute myocardial infarction (MI) (10 patients), elective percutaneous transluminal coronary angioplasty (PTCA) support (four patients), postcardiotomy failure (four patients), and exposure hypothermia (one patient). Adequate support was achieved in all but one patient. Device flows ranged from 0.2 to 6.0 l/min. There were six survivors (elective PTCA support, three patients; cardiac arrest during catheterization, three patients). Complications included bleeding (15 patients), deep venous thrombosis (three patients), and pump failure (one patient). A portable ECMO system has been developed that allows rapid institution of circulatory support.

    Abstract: We present a case of a patient with factor V Leiden with an antithrombin III activity of 67% who received a successful aortic valve replacement supported by cardiopulmonary bypass (CPB). A safe level of anticoagulation was achieved by monitoring activated clotting time (ACT) and heparin concentration ensuring adequate anticoagulation throughout the procedure. Results from ACT, heparin dose response, heparin protamine titration, and thrombelastography are given. Factor V Leiden patients can be safely anti-coagulated using heparin for CPB procedures when monitored with ACT, heparin protamine titration, and thrombelastography. Postoperative chest tube losses were 360 mL, less than half our institutional average. Anticoagulation for the pre-and post-operative phase is also discussed. PMID:26834284

    a device that provides positive pressure ventilation. Surveys conducted to assess the adequacy of manual resuscitators to American Society for Testing and Materials standards show that several factors affect manual ventilation. However, results are conflicting. The aim of this study was to verify evidence of factors that influence pediatric/adult pulmonary ventilation with manual resuscitator by a systematic review. DATA SOURCE: Original articles indexed in Medline, Lilacs and SciELO published from January 1986 to March 2011. The key-words used were: "manual resuscitator", "manual ventilation", "positive pressure ventilation" in Portuguese and English, as well as "bag-valve". DATA SYNTHESIS: 45 articles were selected, most of them experimental. The studies compared manual resuscitator brands and models, and analyzed the physical characteristics of professionals. The effectiveness of ventilation with manual resuscitator depends on the brand, model and functional characteristics of the equipment. Ventilation also varies with the education, training and experience of the professional who handles the equipment. Other factors that can influence effectiveness are the manual resuscitator compression form, the use of a pressure relief valve and the flow of oxygen provided to the manual resuscitator. CONCLUSIONS: The variability of ventilatory parameters during manual resuscitation does not allow a standardization of the technique, being harmful to cardiopulmonary resuscitation. Although most manual resuscitator seem to follow international standards, the equipment must be evaluated in the clinical settings. There are few studies about pediatric and neonatal manual resuscitator models.

    Full Text Available Birth Asphyxia is considered to be one of the leading causes of neonatal mortality around the world. Asphyxiated neonates require skilled resuscitation to survive the neonatal period. The project aims to train health professionals in a basic newborn care using a prototype with an ultimate objective to have one person at every delivery trained in neonatal resuscitation. This prototype will be a user-friendly device with which one can get trained in performing neonatal resuscitation in resource-limited settings. The prototype consists of a Force Sensing Resistor (FSR that measures the pressure applied and is interfaced with Arduino® which controls the Liquid Crystal Display (LCD and Light Emitting Diode (LED indication for pressure and compression counts. With the increase in population and absence of proper medical care, the need for neonatal resuscitation program is not well addressed. The proposed work aims at offering a promising solution for training health care individuals on resuscitating newborn babies under low resource settings.

    Full Text Available Introduction: The objective of our study was to estimate the incidence of prescribing medication errors specifically made by a trainee and identify factors associated with these errors during the simulated resuscitation of a critically ill child. Methods: The results of the simulated resuscitation are described. We analyzed data from the simulated resuscitation for the occurrence of a prescribing medication error. We compared univariate analysis of each variable to medication error rate and performed a separate multiple logistic regression analysis on the significant univariate variables to assess the association between the selected variables. Results: We reviewed 49 simulated resuscitations . The final medication error rate for the simulation was 26.5% (95% CI 13.7% - 39.3%. On univariate analysis, statistically significant findings for decreased prescribing medication error rates included senior residents in charge, presence of a pharmacist, sleeping greater than 8 hours prior to the simulation, and a visual analog scale score showing more confidence in caring for critically ill children. Multiple logistic regression analysis using the above significant variables showed only the presence of a pharmacist to remain significantly associated with decreased medication error, odds ratio of 0.09 (95% CI 0.01 - 0.64. Conclusion: Our results indicate that the presence of a clinical pharmacist during the resuscitation of a critically ill child reduces the medication errors made by resident physician trainees.

    Full Text Available Abstract Background Healthcare professionals have shown concern about performing mouth-to-mouth ventilation due to the risks to themselves with the procedure. However, little is known about healthcare professionals' fears and attitudes to start CPR and the impact of training. Objective To examine whether there were any changes in the attitudes among healthcare professionals to performing CPR from before to after training. Methods Healthcare professionals from two Swedish hospitals were asked to answer a questionnaire before and after training. The questions were relating to physical and mental discomfort and attitudes to CPR. Statistical analysis used was generalized McNemar's test. Results Overall, there was significant improvement in 10 of 11 items, reflecting various aspects of attitudes to CPR. All groups of health care professionals (physicians, nurses, assistant nurses, and "others" = physiotherapists, occupational therapists, social welfare officers, psychologists, biomedical analysts felt more secure in CPR knowledge after education. In other aspects, such as anxiety prior to a possible cardiac arrest, only nurses and assistant nurses improved. The concern about being infected, when performing mouth to mouth ventilation, was reduced with the most marked reduction in physicians (75%; P Conclusion In this hospital-based setting, we found a positive outcome of education and training in CPR concerning healthcare professionals' attitudes to perform CPR. They felt more secure in their knowledge of cardiopulmonary resuscitation. In some aspects of attitudes to resuscitation nurses and assistant nurses appeared to be the groups that were most markedly influenced. The concern of being infected by a disease was low.

    2015-12-01

    Cardiac arrest is the most common cause of death in North America. Neurocritical care interventions, including targeted temperature management (TTM), have significantly improved neurological outcomes in patients successfully resuscitated from cardiac arrest. Therefore, resuscitation following cardiac arrest was chosen as an emergency neurological life support protocol. Patients remaining comatose following resuscitation from cardiac arrest should be considered for TTM. This protocol will review induction, maintenance, and re-warming phases of TTM, along with management of TTM side effects. Aggressive shivering suppression is necessary with this treatment to ensure the maintenance of a target temperature. Ancillary testing, including electrocardiography, computed tomography and/or magnetic resonance imaging of the brain, continuous electroencephalography monitoring, and correction of electrolyte, blood gas, and hematocrit changes, are also necessary to optimize outcomes.

    Initial management of minor and moderate, uncomplicated burn injury focuses on wound management and patient comfort. Initial management of patients with major burn injury requires airway support, fluid resuscitation for burn shock, treatment for associated trauma and preexisting medical conditions, management of adynamic ileus, and initial wound treatment. Fluid resuscitation, based on assessment of the extent and depth of burn injury, requires administration of intravenous fluids using resuscitation formula guidelines for the initial 24 hours after injury. Inhalation injury complicates flame burns and increases morbidity and mortality. Electrical injury places patients at risk for cardiac arrest, metabolic acidosis, and myoglobinuria. Circumferential full-thickness burns to extremities compromise circulation and require escharotomy or fasciotomy. Circumferential torso burns compromise air exchange and cardiac return. Loss of skin function places patients at risk for hypothermia, fluid and electrolyte imbalances, and systemic sepsis. The first 24 hours after burn injury require aggressive medical management to assure survival and minimize complications. PMID:8489882

    Oxygen was used in neonatal resuscitation from 1780, within 5 years of its detection. It rapidly gained general acceptance and infiltrated delivery rooms and, a century later, neonatal special care units. After 217 years without scientific evidence, the use of oxygen for neonatal resuscitation has recently been questioned. Continuous distending airway pressure for oxygen administration was available at the beginning of the 20th century, but was not widely accepted. Alkali and analeptic drugs gained widespread but short-lived use after the Second World War.

We report a case of successful prolonged resuscitation of a pediatric patient in hypothermic cardiac arrest who showed severe metabolic derangements and went on to make a rapid and full neurologic recovery without the use of extracoproreal rewarming or mechanical cardiac support. Many ground and air medical emergency medical service programs have policies against interfacility transfer of patients in hypothermic cardiac arrest, calling into question the need to revise current protocols.

    Damage control resuscitation (DCR) has become a more widely adopted acute management strategy over the past decade. A cornerstone of this strategy is the performance of an initial limited surgical intervention for the control of active bleeding and contamination. This technique is indicated where significant physiological compromise exists and immediate surgical intervention is required. This damage control surgery itself is completed judiciously to allow a period of resuscitative stabilisation before later definitive surgical solutions. This discussion describes the three further principles of DCR and then explores the rationale and drivers behind the development of this approach. PMID:26315261

    IMV is a combination of spontaneous and mechanical ventilation. For numerous reasons, IMV is potentially more advantageous than conventional techniques. By maintaining spontaneous breathing, mechanical augmentation can be titrated to adjust alveolar minute ventilation levels to normal, thereby decreasing the incidence of respiratory alkalemia. There are major differences between the cardiopulmonary effects of IMV and conventional mechanical ventilation. Spontaneous inspiration decreases Ppl and results in better distribution of inspired gas, a better V/Q, and less physiological dead space. In addition, transmural filling pressures, venous return, and cardiac output are more normal than during conventional mechanical ventilation. Maintenance of spontaneous ventilation lowers mean Paw and pulmonary vascular resistance. If venous admixture occurs, it can be minimized by titrating PEEP. Thus, more effective therapy for hypoxemia is possible. If spontaneous breathing is to persist and be efective, work-of-breathing must be minimized. This can be accomplished best when a continuous flow of gas provides optimal CPAP to maintain FRC and to minimize the effects of decreased compliance without depressing cardiac function.

    Full Text Available Abstract Background To summarize the diagnostic and therapeutic experiences on the patients who suffered abdominal complications after cardiovascular surgery with cardiopulmonary bypass(CPB. Methods A total of 2349 consecutive patients submitted to cardiovascular surgery with CPB in our hospital from Jan 2004 to Dec 2010 were involved. The clinical data of any abdominal complication, including its incidence, characters, relative risks, diagnostic measures, medical or surgical management and mortality, was retrospectively analyzed. Results Of all the patients, 33(1.4% developed abdominal complications postoperatively, including 11(33.3% cases of paralytic ileus, 9(27.3% of gastrointestinal haemorrhage, 2(6.1% of gastroduodenal ulcer perforation, 2(6.1% of acute calculus cholecystitis, 3(9.1% of acute acalculus cholecystitis, 4(12.1% of hepatic dysfunction and 2(6.1% of ischemia bowel diseases. Of the 33 patients, 26 (78.8% accepted medical treatment and 7 (21.2% underwent subsequent surgical intervention. There were 5(15.2% deaths in this series, which was significantly higher than the overall mortality (2.7%. Positive history of peptic ulcer, advanced ages, bad heart function, preoperative IABP support, prolonged CPB time, low cardiac output and prolonged mechanical ventilation are the risk factors of abdominal complications. Conclusions Abdominal complications after cardiovascular surgery with CPB have a low incidence but a higher mortality. Early detection and prompt appropriate intervention are essential for the outcome of the patients.

  3. The Cardiopulmonary effect of passive movement

    Full Text Available Eleven articles were reviewed on the cardiopulmonary effects of passive movements. These included two articles on theneurological effects of passive movements. Of the eleven articles, four were considered to have level II evidence in accordance with Sackett’s rules of evidence. There was little consensus regarding the rate or duration of passive movements. There were some suggestions that upper limb movement produces a greater ventilatory response than lower limb movement. There was a statistically significant increase (p< 0.05 in minute ventilation when the movement was done at a rate of 40 repetitions per minute or more, but this change may not be clinically significant. Passive movements were not detrimental to neurosurgical patients with a normal or slightly elevated intracranial pressure, although the values of the intracranial pressure were not stated.  The studies were limited in that eight of the eleven had small sample sizes and most studies were conducted using normal subjects. Further studies with higher levels of evidence need to be  conducted to verify any results reported to date in the literature. Studies that are relevant to clinical practice also need to be conducted in populations such as sedated intensive care patients.

    Exercise intolerance, indicated by dyspnea and fatigue during exertion, is a cardinal manifestation of heart failure (HF). Cardiopulmonary exercise testing (CPET) precisely defines maximum exercise capacity through measurement of peak oxygen uptake (VO2). Peak VO2 values have a critical role in informing patient selection for advanced HF interventions such as heart transplantation and ventricular assist devices. Oxygen uptake and ventilatory patterns obtained during the submaximal portion of CPET are also valuable to recognize because of their ease of ascertainment during low-level exercise, relevance to ability to perform activities of daily living, independence from volitional effort, and strong relationship to prognosis in HF. The ability of peak VO2 and other CPET variables to be measured reproducibly and to accurately reflect HF severity is increasingly recognized and endorsed by scientific statements. Integration of CPET with invasive hemodynamic monitoring and cardiac imaging during exercise provides comprehensive characterization of multisystem reserve capacity that can inform prognosis and the need for cardiac interventions. Here, we review both practical aspects of conducting CPETs in patients with HF for clinical and research purposes as well as interpretation of gas exchange patterns across the spectrum of preclinical HF to advanced HF.

    Hantavirus cardiopulmonary syndrome has a high mortality rate, and early connection to extracorporeal membrane oxygenation has been suggested to improve outcomes. We report the case of a patient with demonstrated Hantavirus cardiopulmonary syndrome and refractory shock who fulfilled the criteria for extracorporeal membrane oxygenation and responded successfully to high volume continuous hemofiltration. The implementation of high volume continuous hemofiltration along with protective ventilation reversed the shock within a few hours and may have prompted recovery. In patients with Hantavirus cardiopulmonary syndrome, a short course of high volume continuous hemofiltration may help differentiate patients who can be treated with conventional intensive care unit management from those who will require more complex therapies, such as extracorporeal membrane oxygenation.

    2009-08-01

    Full Text Available Abstract Background Traumatic injury is a leading cause of morbidity and mortality in developed countries worldwide. Recent studies suggest that many deaths are preventable if injuries are recognized and treated in an expeditious manner – the so called 'golden hour' of trauma. Ultrasound revolutionized the care of the trauma patient with the introduction of the FAST (Focused Assessment with Sonography for Trauma examination; a rapid assessment of the hemodynamically unstable patient to identify the presence of peritoneal and/or pericardial fluid. Since that time the use of ultrasound has expanded to include a rapid assessment of almost every facet of the trauma patient. As a result, ultrasound is not only viewed as a diagnostic test, but actually as an extension of the physical exam. Methods A review of the medical literature was performed and articles pertaining to ultrasound-assisted assessment of the trauma patient were obtained. The literature selected was based on the preference and clinical expertise of authors. Discussion In this review we explore the benefits and pitfalls of applying resuscitative ultrasound to every aspect of the initial assessment of the critically injured trauma patient.

    Full Text Available Background. Basic life support (BLS training with hands-on practice can improve performance during simulated cardiac arrest, although the optimal duration for BLS training is unknown. This study aimed to assess the effectiveness of various BLS training durations for acquiring cardiopulmonary resuscitation (CPR and automated external defibrillator (AED skills. Methods. We randomised 485 South Korean nonmedical college students into four levels of BLS training: level 1 (40 min, level 2 (80 min, level 3 (120 min, and level 4 (180 min. Before and after each level, the participants completed questionnaires regarding their willingness to perform CPR and use AEDs, and their psychomotor skills for CPR and AED use were assessed using a manikin with Skill-Reporter™ software. Results. There were no significant differences between levels 1 and 2, although levels 3 and 4 exhibited significant differences in the proportion of overall adequate chest compressions (p<0.001 and average chest compression depth (p=0.003. All levels exhibited a greater posttest willingness to perform CPR and use AEDs (all, p<0.001. Conclusions. Brief BLS training provided a moderate level of skill for performing CPR and using AEDs. However, high-quality skills for CPR required longer and hands-on training, particularly hands-on training with AEDs.

    This research investigated leadership and effectiveness of teams operating in a high-velocity environment, specifically trauma resuscitation teams. On the basis of the literature and their own ethnographic work, the authors proposed and tested a contingency model in which the influence of leadership on team effectiveness during trauma resuscitation differs according to the situation. Results indicated that empowering leadership was more effective when trauma severity was low and when team experience was high. Directive leadership was more effective when trauma severity was high or when the team was inexperienced. Findings also suggested that an empowering leader provided more learning opportunities than did a directive leader. The major contribution of this article is the linkage of leadership to team effectiveness, as moderated by relatively specific situational contingencies.

    Full Text Available Functional systemic approach to the resuscitation and intensive care may be considered as a direct correlation between analysis and synthesis, induction and deduction, and, in general, between the formal and dialectical categories. The realization of this system should be started with the interaction and formation of the final beneficial result. Therefore the experience assessment on the basis of functional systematic approach will enable us to formulate more precisely the subject and methods of resuscitation from the philosophical point of view taking into consideration the interaction of the human life integrity with death phenomenon as fixed in ontogenesis and will allow to methodically justify the distinguishing of functional systems and standard processes both in sanogenesis and thanatogenesis.

  18. The ebb and flow of fluid (as in resuscitation).

    2015-04-01

    Since the early 1960's "resuscitation" following major trauma involved use of replacement crystalloid fluid/estimated blood loss in volumes of 3/1, in the ambulance, emergency room, operating room and surgical intensive care unit. During the past 20 years, MAJOR paradigm shifts have occurred in this concept. As a result hypotensive resuscitation with a view towards restriction of crystalloid, and prevention of complications has occurred. Improved results in both civilian and military environments have been reported. As a result there is new focus on trauma surgical involvement in all aspects of trauma patient management, focus on early aggressive surgical approaches (which may or may not involve an operation), and movement from crystalloid to blood, plasma, and platelet replacement therapy.

    Neonatal resuscitation is one of the most frequently performed procedures, and it is often successful if the ventilation applied is adequate. Over the last decade, interest in seeking objectivity in evaluating the infant's condition at birth or the adequacy and effect of the interventions applied has markedly increased. Clinical parameters such as heart rate, color, and chest excursions are difficult to interpret and can be very subjective and subtle. The use of ECG, pulse oximetry, capnography, and respiratory function monitoring can add objectivity to the clinical assessment. These physiological parameters, with or without the combination of video recordings, can not only be used directly to guide care but also be used later for audit and teaching purposes. Further studies are needed to investigate whether this will improve the quality of delivery room management. In this narrative review, we will give an update of the current developments in monitoring neonatal resuscitation. PMID:27148507

  3. Metabolic resuscitation in sepsis: a necessary step beyond the hemodynamic?

    2016-07-01

    Despite the advances made in monitoring and treatment of sepsis and septic shock, many septic patients ultimately develop multiple organ dysfunction (MODS) and die, suggesting that other players are involved in the pathophysiology of this syndrome. Mitochondrial dysfunction occurs early in sepsis and has a central role in MODS development. MODS severity and recovery of mitochondrial function have been associated with survival. In recent clinical and experimental investigations, mitochondrion-target therapy for sepsis and septic shock has been suggested to reduce MODS severity and mortality. This intervention, which might be named "metabolic resuscitation", would lead to improved mitochondrial activity afforded by pharmacological and nutritional agents. Of particular interest in this therapeutic strategy is thiamine, a water-soluble vitamin that plays an essential role in cellular energy metabolism. Critical illness associated with hypermetabolic states may predispose susceptible individuals to the development of thiamine deficiency, which is not usually identified by clinicians as a source of lactic acidosis. The protective effects of thiamine on mitochondrial function may justify supplementation in septic patients at risk of deficiency. Perspectives of supplementation with other micronutrients (ascorbic acid, tocopherol, selenium and zinc) and potential metabolic resuscitators [coenzyme Q10 (CoQ10), cytochrome oxidase (CytOx), L-carnitine, melatonin] to target sepsis-induced mitochondrial dysfunction are also emerging. Metabolic resuscitation may probably be a safe and effective strategy in the treatment of septic shock in the future. However, until then, preliminary investigations should be replicated in further researches for confirmation. Better identification of groups of patients presumed to benefit clinically by a certain intervention directed to "mitochondrial resuscitation" are expected to increase driven by genomics and metabolomics.

    2016-09-01

    Since 1968, when Baxter and Shires developed the Parkland formula, little progress has been made in the field of fluid therapy for burn resuscitation, despite advances in haemodynamic monitoring, establishment of the 'goal-directed therapy' concept, and the development of new colloid and crystalloid solutions. Burn patients receive a larger amount of fluids in the first hours than any other trauma patients. Initial resuscitation is based on crystalloids because of the increased capillary permeability occurring during the first 24 h. After that time, some colloids, but not all, are accepted. Since the emergence of the Pharmacovigilance Risk Assessment Committee alert from the European Medicines Agency concerning hydroxyethyl starches, solutions containing this component are not recommended for burns. But the question is: what do we really know about fluid resuscitation in burns? To provide an answer, we carried out a non-systematic review to clarify how to quantify the amount of fluids needed, what the current evidence says about the available solutions, and which solution is the most appropriate for burn patients based on the available knowledge.

    The need for delivery resuscitation of the newborn cannot be predicted in most cases; therefore it is judicious to train all providers who may be involved in the delivery of newborns to follow guidelines developed to improve outcome, especially in the presence of transitional asphyxia. The Neonatal Resuscitation Program emphasizes basic steps of warming, drying, suctioning, and adequately ventilating the newborn. It also addresses current theories regarding resuscitation of the low birthweight newborns, infants with meconium aspiration, and medication use. The NRP applies to all acute-care hospitals that provide delivery services and those at which a respiratory therapist is likely to be present in the high-risk delivery or unanticipated delivery-room resuscitation. Outcomes have not been well documented and more clinical research is needed to identify which therapeutic strategies promote the best survival in this population. A topic that should be included in the NRP of the future is exogenous surfactant delivery. Respiratory distress syndrome has been a significant cause of death and morbidity in prematurely born neonates. Exogenous surfactant therapy has had a dramatic effect on the death rate of premature infants and on the incidence of respiratory distress syndrome. Current methods of surfactant administration demand that personnel proficient in management of the low birthweight newborn be present. As hospitals with all levels of nurseries continue to receive the prematurely delivered newborn and better methods to administer surfactant are discovered, the NRP could add information and a skills laboratory on surfactant administration. A trained cadre of health professionals who are proficient in the specific resuscitation skills required in pediatric patients can make a difference. The infant and child have different anatomy, physiology, and disease etiology that need to be emphasized and understood by the pediatric caregiver. The Pediatric Advanced Life

    Percutaneous cardiopulmonary support (PCPS) is a widely accepted treatment for severe cardiopulmonary failure. This system, which uses a percutaneous approach and autopriming devices, can be rapidly applied in emergency situations. We sought to identify the risk factors that could help predict in-hospital mortality, and to assess its outcomes in survivors. During a 2-yr period, 50 patients underwent PCPS for the treatment of severe cardiopulmonary failure, and of those, 22 (44%) were classified as survivors and 28 (56%) as non-survivors. We compared the 2 groups for risk factors of in-hospital mortality and to establish proper PCPS timing. Twenty patients underwent PCPS for acute myocardial infarction, 20 for severe cardiopulmonary failure after cardiac surgery, 7 for acute respiratory distress syndrome, and 3 for acute myocarditis. Multivariate analysis showed that an acute physiology, age, and chronic health evaluation (APACHE) III score >or=50 prior to PCPS was the only significant predictor of in-hospital mortality (P=0.001). Overall 18-month survival was 42.2%. Cox analysis showed patients with APACHE III scores >or=50 had a poor prognosis (P=0.001). Earlier application of PCPS, and other preemptive strategies designed to optimize high-risk patients, may improve patient outcomes. Identifying patients with high APACHE scores at the beginning of PCPS may predict in-hospital mortality. Survivors, particularly those with higher APACHE scores, may require more frequent follow-up to improve overall survival.

    Full Text Available Background: Basic Life Support (BLS/Cardiopulmonary Resuscitation (CPR is an important part of emergency medical care. This study is done among medical undergraduate students, to know their knowledge and perceptions about BLS, as they are going to face such situations in future, as doctors. Materials and Methods: A questionnaire-based study was conducted among 377 medical undergraduate students. The questionnaire included the following parts: (1 Basic characteristics of the study participants, (2 Knowledge about BLS/CPR, (3 Perceptions about BLS/CPR. The components of knowledge and perception based questions were scored. The data was analyzed using SPSS version 12. Results were expressed as proportions in appropriate tables and graphs. Student's Independent 't' test was used to compare means between students who had undergone previous training if any and those who had no such training. Results: Out of 377 students, majority (84.6% had heard of BLS/CPR. Some of them (30.6% could give the correct order of performing CPR as per the AHA guidelines (Year 2010. Few (18.9% had undergone prior training in BLS, whereas, only 17.7% had been in a situation that needed BLS/CPR. Nearly half (50.2% were not confident of performing BLS/CPR. Comparison of the students revealed that students who had training had higher mean scores for 'response to a situation needing BLS/CPR' and 'signs of successful resuscitation', though there was little difference in their knowledge of 'indications for BLS/CPR. Overall perception was not favourable and the students were not confident of performing BLS/CPR. Conclusions: The students need to be taught and trained in the CPR/BLS early in the curriculum to improve their knowledge. Repeated training would increase their confidence.

    To change the stretch on cardiopulmonary mechanoreceptors, large shifts of blood in the capacity space were elicited by tilting and by exerting positive lower body pressure in the tilted position. Twelve volunteers underwent invasive hemodynamic studies and in 10 other subjects cardiac size was determined by radionuclide cardiography. In all 22 subjects tilting caused the expected increase of renin, which was abolished by lower body compression. Decompression caused renin to increase again. Right atrial pressure in invasive studies and end-systolic and end-diastolic counts in noninvasive studies showed a significant and strong negative correlation with renin and norepinephrine levels. Thus, the degree of stretch of the cardiopulmonary mechanoreceptors is a major determinant of reflex regulation of renin release in humans.

    Perioperative hyperglycemia, aggravated by cardiopulmonary bypass, is associated with adverse outcome in adult and pediatric patients. Whereas hyperglycemia was originally perceived as an adaptive response to surgical stress, it is now clear that glycemic control is a strategy to reduce adverse outcomes after cardiac surgery and cardiopulmonary bypass. The optimal blood glucose target, whether or not glycemic control should be initiated already intraoperatively, and whether or not perioperative glucose administration affects the impact of glycemic control on ischemia-reperfusion damage remain open questions. Hypoglycemia, the risk of which is increased with glycemic control, is also associated with adverse outcomes. However, it remains controversial whether brief episodes of hypoglycemia, rapidly corrected during glycemic control, have adverse effects on outcome. This review gives an overview of the currently available literature on glycemic control during and after cardiac surgery and focuses on the indicated open questions about this intervention for this specific patient population.

  19. Lethal systemic Degos disease with prominent cardio-pulmonary involvement

    International Nuclear Information System (INIS)

    Degos disease (DD) is a rare obstructive vasculopathy characterized by distinctive skin lesions. Involvement of the soles, palms and genitalia is rare. In most cases disease has an unfavorable course and involves gastrointestinal tract, central nervous system and occasionally other organs. Pleural and pericardial involvements are usually minor manifestations with prolonged course. Death occurs in approximately 50% of the patients usually due to intestinal perforation or central nervous system bleeding. We describe a 48-year-old man of lethal systemic DD. Widespread skin lesions with involvement of palm plantar surfaces, genitalia and scalp were ignored for 3 years, whereas the disease revealed its own malignant nature. The disorder progressed to nervous, gastrointestinal and cardiopulmonary system that led to death after 5 months from onset of systemic involvement as severe restrictive cardio-pulmonary insufficiency. Autopsy showed diffuse fibrotic changes in serial membranes and internal organs. (author)

    The Utstein model for evaluating cardio pulmonary resuscitation (CPR) has been continuously improved since it was established in 1991 and has become the international Utstein model for evaluating CPR. But the promotion and application of Utstein model lag behind those of international CPR & cardiovascular emergency guide. Clinicians should strengthen the understanding and application of Utstein model for evaluating CPR in order to exactly evaluate implementary effect, standardize operational procedures of CPR and improve resurgent prognosis of patients with cardiac arrest.%心肺复苏(cardiopulmonary resuscitation,CPR)结果评估Utstein模式自1991年制定以来不断完善与提高,从而形成了国际共识的CPR结果评估Utstein模式.然而CPR结果评估Utstein模式在推广及应用方面远不及国际CPR与心血管急救指南.为准确评估CPR实施效果,规范CPR操作程序,有必要加强临床医生对CPR结果评估Utstein模式的认识并积极推广应用,以改善心脏骤停患者复苏预后.

    Objectives The goal of our study was to shed light on educational methods to strengthen medical students' cardiopulmonary resuscitation (CPR) leadership and team skills in order to optimise CPR understanding and success using didactic videos and high-fidelity simulations. Design An observational study. Setting A tertiary medical centre in Northern Taiwan. Participants A total of 104 5–7th year medical students, including 72 men and 32 women. Interventions We provided the medical students with a 2-hour training session on advanced CPR. During each class, we divided the students into 1–2 groups; each group consisted of 4–6 team members. Medical student teams were trained by using either method A or B. Method A started with an instructional CPR video followed by a first CPR simulation. Method B started with a first CPR simulation followed by an instructional CPR video. All students then participated in a second CPR simulation. Outcome measures Student teams were assessed with checklist rating scores in leadership, teamwork and team member skills, global rating scores by an attending physician and video-recording evaluation by 2 independent individuals. Results The 104 medical students were divided into 22 teams. We trained 11 teams using method A and 11 using method B. Total second CPR simulation scores were significantly higher than first CPR simulation scores in leadership (p<0.001), teamwork (p<0.001) and team member skills (p<0.001). For methods A and B students' first CPR simulation scores were similar, but method A students' second CPR simulation scores were significantly higher than those of method B in leadership skills (p=0.034), specifically in the support subcategory (p=0.049). Conclusions Although both teaching strategies improved leadership, teamwork and team member performance, video exposure followed by CPR simulation further increased students' leadership skills compared with CPR simulation followed by video exposure.

    Objective To study the hormonal and metabolic responses of fetal lamb during cardiopulmonary bypass.Methods Six pregnant ewes underwent fetal cardiopulmonary bypasses with artificial oxygenators and roller pumps for 30 minutes, which maintained the blood gas value at the fetal physiological level. The fetal blood pressure, heart rate, pH value and blood lactate levels were monitored. The levels of catecholamine, cortisol and insulin were measured pre-bypass and then again 30 minutes later. The blood glucose and free fatty acid levels were monitored continuously during the bypass. Fetal hepatic PAS staining was also carried out.Results There were no changes before and during the bypass in fetal blood pressure, heart rate and blood gas. However, pH values decreased and blood lactate levels increased (P<0.05). The fetal catecholamine and cortisol levels increased significantly (P<0.01), while the levels of insulin did not change. The blood glucose and free fatty acid levels increased at the beginning of the bypass (P<0.01), and then gradually slowed down during the bypass. The fetal hepatic PAS staining showed that hepatic glycogen was consumed in large amounts. After 30 minutes of bypass, the fetal lamb would not survive more than 1 hour.Conclusion The fetal lamb has a strong negative reaction to cardiopulmonary bypass.

    Both the 1992 and the 1997 recovery positions were demonstrated to 100 employees attending for Basic Life Support resuscitation training at a district general hospital (Chesterfield and North Derbyshire Royal Hospital NHS Trust). They used both positions, experiencing being the first-aider and the casualty and then completed a closed questionnaire. The results were evaluated from this 100% response. In every aspect the 1992 or 'How' position was preferred both in terms of ease of use and comfort during the procedure by the majority of each sample group. In every comparison the 1992 position was preferred highly significantly, (P < 0.001) using chi-square statistical analysis. PMID:10078805

    Resuscitation has the ability to reverse premature death. It can also prolong terminal illness, increase discomfort, and consume resources. The do-not-resuscitate (DNR) order and advance directives are still a debated issue in critical care. This review will focus on several aspects, regarding withholding and/or withdrawing therapies and advance directives in different continents. It is widely known that there is a great diversity of cultural and religious beliefs in society, and therefore, some critical ethical and legal issues have still to be solved. To achieve a consensus, we believe in the priority of continuing education and training programs for health care professionals. It is our opinion that a serious reflection on ethical values and principles would be useful to understand the definition of medical professionalism to make it possible to undertake the best way to avoid futile and aggressive care. There is evidence of the lack of DNR order policy worldwide. Therefore, it appears clear that there is a need for standardization. To improve the attitude about the DNR order, it is necessary to achieve several goals such as: increased communication, consensus on law, increased trust among patients and health care systems, and improved standards and quality of care to respect the patient's will and the family's role.

    Acute pancreatitis (AP) is a frequent disease with degrees of increasing severity responsible for high morbidity. Despite continuous improvement in care, mortality remains significant. Because hypovolemia, together with microcirculatory dysfunction lead to poor outcome, fluid therapy remains a cornerstone of the supportive treatment. However, poor clinical evidence actually support the aggressive fluid therapy recommended in recent guidelines since available data are controversial. Fluid management remains unclear and leads to current heterogeneous practice. Different strategies may help to improve fluid resuscitation in AP. On one hand, integration of fluid therapy in a global hemodynamic resuscitation has been demonstrated to improve outcome in surgical or septic patients. Tailored fluid administration after early identification of patients with high-risk of poor outcome presenting inadequate tissue oxygenation is a major part of this strategy. On the other hand, new decision parameters have been developed recently to improve safety and efficiency of fluid therapy in critically ill patients. In this review, we propose a personalized strategy integrating these new concepts in the early fluid management of AP. This new approach paves the way to a wide range of clinical studies in the field of AP. PMID:25473163

    Background: Adequate ventilation is the key to successful neonatal resuscitation. Positive pressure ventilation (PPV) is initiated with manual ventilation devices via face masks. These devices may be used with a manometer to measure airway pressures delivered. The expiratory tidal volume measured at the mask (VTE(mask)) is a good estimate of the tidal volume delivered during simulated neonatal resuscitation. Aim: To assess the effect of viewing a manometer on the peak inspiratory pressures used, the volume delivered, and leakage from the face mask during PPV with two manual ventilation devices in a model of neonatal resuscitation. Methods: Participants gave PPV to a modified resuscitation mannequin using a Laerdal infant resuscitator and a Neopuff infant resuscitator at specified pressures ensuring adequate chest wall excursion. Each participant gave PPV to the mannequin with each device twice, viewing the manometer on one occasion and unable to see the manometer on the other. Data from participants were averaged for each device used with the manometer and without the manometer separately. Results: A total of 7767 inflations delivered by the 18 participants were recorded and analysed. Peak inspiratory pressures delivered were lower with the Laerdal device. There were no differences in leakage from the face mask or volumes delivered. Whether or not the manometer was visible made no difference to any measured variable. Conclusions: Viewing a manometer during PPV in this model of neonatal resuscitation does not affect the airway pressure or tidal volumes delivered or the degree of leakage from the face mask.

    Effective resuscitation is critical in reducing mortality and morbidity rates of patients with acute burns. To this end, guidelines and formulas have been developed to define infusion rates and volume requirements during the first 48 hours postburn. Even with these standardized resuscitation guidelines, however, over- and under-resuscitation are not uncommon. Two approaches to adjust infusion rate are decision-assist and closed-loop algorithms based on levels of urinary output. Specific decision assist guidelines or a closed-loop system using computer-controlled feedback technology that supplies automatic control of infusion rates can potentially achieve better control of urinary output. In a properly designed system, closed-loop control has the potential to provide more accurate titration rates, while lowering the incidence of over- and under-resuscitation. Because the system can self-adjust based on monitoring inputs, the technology can be pushed to environments such as combat zones where burn resuscitation expertise is limited. A closed-loop system can also assist in the management of mass casualties, another scenario in which medical expertise is often in short supply. This article reviews the record of fluid balance of contemporary burn resuscitation and approaches, as well as the engineering efforts, animal studies, and algorithm development of our most recent autonomous systems for burn resuscitation.

    2015-01-01

    Full Text Available Background: Transfusion of blood remains the gold standard for fluid resuscitation from hemorrhagic shock. Hemoglobin (Hb within the red blood cell transports oxygen and modulates nitric oxide (NO through NO scavenging and nitrite reductase. Aims: This study was designed to examine the effects of incorporating a novel NO modulator, RRx-001, on systemic and microvascular hemodynamic response after blood transfusion for resuscitation from hemorrhagic shock in a hamster window chamber model. In addition, to RRx-001 the role of low dose of nitrite (1 × 10−9 moles per animal supplementation after resuscitation was studied. Materials and Methods: Severe hemorrhage was induced by arterial controlled bleeding of 50% of the blood volume (BV and the hypovolemic state was maintained for 1 h. The animals received volume resuscitation by an infusion of 25% of BV using fresh blood alone or with added nitrite, or fresh blood treated with RRx-001 (140 mg/kg or RRx-001 (140 mg/kg with added nitrite. Systemic and microvascular hemodynamics were followed at baseline and at different time points during the entire study. Tissue apoptosis and necrosis were measured 8 h after resuscitation to correlate hemodynamic changes with tissue viability. Results: Compared to resuscitation with blood alone, blood treated with RRx-001 decreased vascular resistance, increased blood flow and functional capillary density immediately after resuscitation and preserved tissue viability. Furthermore, in RRx-001 treated animals, both mean arterial pressure (MAP and met Hb were maintained within normal levels after resuscitation (MAP >90 mmHg and metHb <2%. The addition of nitrite to RRx-001 did not significantly improve the effects of RRx-001, as it increased methemoglobinemia and lower MAP. Conclusion: RRx-001 alone enhanced perfusion and reduced tissue damage as compared to blood; it may serve as an adjunct therapy to the current gold standard treatment for resuscitation from

    Full Text Available Introduction: Respiratory failure is a common problem in emergency medicine (EM and critical care medicine (CCM. However, little is known about the resuscitation of critically ill patients prior to emergency endotracheal intubation (EETI. Our aim was to describe the resuscitation practices of EM and CCM physicians prior to EETI. Methods: A cross-sectional survey was developed and tested for content validity and retest reliability by members of the Canadian Critical Care Trials Group. The questionnaire was distributed to all EM and CCM physician members of three national organizations. Using three clinical scenarios (trauma, pneumonia, congestive heart failure, we assessed physician preferences for use and types of fluid and vasopressor medication in pre-EETI resuscitation of critically ill patients. Results: In total, 1,758 physicians were surveyed (response rate 50.2%, 882/1,758. Overall, physicians would perform pre-EETI resuscitation using either fluids or vasopressors in 54% (1,193/2,203 of cases. Most physicians would “always/often” administer intravenous fluid pre-EETI in the three clinical scenarios (81%, 1,484/1,830. Crystalloids were the most common fluid physicians would “always/often” administer in congestive heart failure (EM 43%; CCM 44%, pneumonia (EM 97%; CCM 95% and trauma (EM 96%; CCM 96%. Pre-EETI resuscitation using vasopressors was uncommon (4.9%. Training in CCM was associated with performing pre-EETI resuscitation (odds ratio, 2.20; 95% CI, [1.44-3.36], p<0.001. Conclusion: Pre-EETI resuscitation is common among Canadian EM and CCM physicians. Most physicians use crystalloids pre-EETI as a resuscitation fluid, while few would give vasopressors. Physicians with CCM training were more likely to perform pre-EETI resuscitation.

    2016-09-01

    Historically, recommendations for neonatal resuscitation were largely based on dogma, but there is renewed interest in performing resuscitation studies at birth. The emphasis for resuscitation following birth asphyxia is administering effective ventilation, as adequate lung aeration leads not only to an increase in oxygenation but also increased pulmonary blood flow and heart rate. To aerate the lung, an initial sustained inflation can increase heart rate, oxygenation, and blood pressure recovery much faster when compared with standard ventilation. Hyperoxia should be avoided, and extra oxygen given to restore cardiac function and spontaneous breathing should be titrated based on oxygen saturations. PMID:27524447

    Full Text Available Abstract A treatment strategy of a difficult and unusual problem is presented. We are reporting a case of a patient who had a documented allergy to heparin and required Cardiac surgery for an ASD closure. The anticoagulation regime used during cardiopulmonary bypass was lepirudin based. This report indicates that r-hirudin provides effective anticoagulation, however unless ECT is monitoring, post operative hemorrhage is encountered. Therefore this case is unique not only because of its rarity but also by the fact that it presents the caveats encountered when ECT is not available.

  17. Metabolic resuscitation in sepsis: a necessary step beyond the hemodynamic?

    2016-01-01

    Despite the advances made in monitoring and treatment of sepsis and septic shock, many septic patients ultimately develop multiple organ dysfunction (MODS) and die, suggesting that other players are involved in the pathophysiology of this syndrome. Mitochondrial dysfunction occurs early in sepsis and has a central role in MODS development. MODS severity and recovery of mitochondrial function have been associated with survival. In recent clinical and experimental investigations, mitochondrion-target therapy for sepsis and septic shock has been suggested to reduce MODS severity and mortality. This intervention, which might be named “metabolic resuscitation”, would lead to improved mitochondrial activity afforded by pharmacological and nutritional agents. Of particular interest in this therapeutic strategy is thiamine, a water-soluble vitamin that plays an essential role in cellular energy metabolism. Critical illness associated with hypermetabolic states may predispose susceptible individuals to the development of thiamine deficiency, which is not usually identified by clinicians as a source of lactic acidosis. The protective effects of thiamine on mitochondrial function may justify supplementation in septic patients at risk of deficiency. Perspectives of supplementation with other micronutrients (ascorbic acid, tocopherol, selenium and zinc) and potential metabolic resuscitators [coenzyme Q10 (CoQ10), cytochrome oxidase (CytOx), L-carnitine, melatonin] to target sepsis-induced mitochondrial dysfunction are also emerging. Metabolic resuscitation may probably be a safe and effective strategy in the treatment of septic shock in the future. However, until then, preliminary investigations should be replicated in further researches for confirmation. Better identification of groups of patients presumed to benefit clinically by a certain intervention directed to “mitochondrial resuscitation” are expected to increase driven by genomics and metabolomics.

Methods 396 patients (except the late-stage cancer, the end-stage chronic disease) with a complete record of cardiac arrest (CA) in the emergency department from December 2006 to November 2011 were retrospectively analyzed, including the analysis of the statistical data of the CPR start time, place, electric defibrillation, tracheal intubation, and mechanical ventilation. Results 165 cases begin to CPR within 5 minutes, 86 cases were successfully rescued and the success rate was 52.1%; 85 cases begin to CPR between 5 to 10 minutes, 29 cases were successfully rescued and the success rate was 34.1%; the other 140 cases begin to CPR after 10 minutes, 0 cases were successfully rescued, which indicates that the success rate within 5 minutes was significantly higher than after 5 minutes; 140 hospital treatment CPR cases, 80 cases were successfully rescued and the success rate was 57.1%, and 256 pre-hospital treatment CPR cases, 35 cases were successfully rescued and the success rate was 13.7%, which indicates the success rate of hospital treatment was significantly higher than that of the pre-hospital treatment; the success rate of CPR using electric defibrillation within 2 minutes was 54.2%, which was much higher than 34.0% success rate of CPR using electric defibrillation after 2 minutes ; the success rate of CPR with endolracheal intubation was 34.1%, much higher than a 13.0% success rate of CPR without endotracheal intubation; the success rate of CPR with both endotracheal intubation and breathing apparatus was 39.1%, much higher than a 10.7% success rate of CPR without breathing apparatus (including patients with and without endotracheal intubation), differences were statistically significant (all P < 0.01). Conclusion Early correct and effective CPR, electric defibrillation and endotracheal intubation are the keys to the success of CPR. To improve the success rate of CPR, professional first aid team construction was strenghened, emergency network was established and improved, and cooperate hospital treatment closely with pre-hospital treatment and the national first aid was popularized so as to further improve the success rate of CPR.

    2009-02-01

    Full Text Available Abstract Background Cardiac arrests are handled by teams rather than by individual health-care workers. Recent investigations demonstrate that adherence to CPR guidelines can be less than optimal, that deviations from treatment algorithms are associated with lower survival rates, and that deficits in performance are associated with shortcomings in the process of team-building. The aim of this study was to explore and quantify the effects of ad-hoc team-building on the adherence to the algorithms of CPR among two types of physicians that play an important role as first responders during CPR: general practitioners and hospital physicians. Methods To unmask team-building this prospective randomised study compared the performance of preformed teams, i.e. teams that had undergone their process of team-building prior to the onset of a cardiac arrest, with that of teams that had to form ad-hoc during the cardiac arrest. 50 teams consisting of three general practitioners each and 50 teams consisting of three hospital physicians each, were randomised to two different versions of a simulated witnessed cardiac arrest: the arrest occurred either in the presence of only one physician while the remaining two physicians were summoned to help ("ad-hoc", or it occurred in the presence of all three physicians ("preformed". All scenarios were videotaped and performance was analysed post-hoc by two independent observers. Results Compared to preformed teams, ad-hoc forming teams had less hands-on time during the first 180 seconds of the arrest (93 ± 37 vs. 124 ± 33 sec, P Conclusion Hands-on time and time to defibrillation, two performance markers of CPR with a proven relevance for medical outcome, are negatively affected by shortcomings in the process of ad-hoc team-building and particularly deficits in leadership. Team-building has thus to be regarded as an additional task imposed on teams forming ad-hoc during CPR. All physicians should be aware that early structuring of the own team is a prerequisite for timely and effective execution of CPR.

    Quality standards no longer allow physicians to delay discussing goals of care and resuscitation. We propose 2 novel strategies for discussing goals and resuscitation on admission. The first, SPAM (determine Surrogate decision maker, determine resuscitation Preferences, Assume full care, and advise them to expect More discussion especially with clinical changes), helps clinicians discover patient preferences and decision maker during routine admissions. The second, UFO-UFO (Understand what they know, Fill in knowledge gaps, ask about desired Outcomes, Understand their reasoning, discuss the spectrum Feasible Outcomes), helps patients with poor or uncertain prognosis or family-team conflict. Using a challenging case example, this article illustrates how SPAM and UFO-UFO can help clinicians have patient-centered resuscitation and goals of care discussions at the beginning of care.

    1987-01-01

    A statewide survey of nurses in perinatal centers was conducted to assess the prevalence of do-not-resuscitate (DNR) policies in neonatal intensive care units (NICUs) and to examine factors influencing nurses in those centers in their compliance with DNR orders. Three nurses in each of 10 perinatal centers were asked to complete a questionnaire on DNR policies and nurses' compliance and to respond to four hypothetical clinical situations. Eighteen of the 27 responding nurses reported the existence of a DNR policy. Factors affecting compliance with DNR orders were agreement that the infant should not be resuscitated (n = 24) or respect for the parents' wishes (n = 19). Nurses' intention to resuscitate despite a DNR order varied, depending on the description of the infant. Multiple regression analyses showed that subjective norms (beta = .41 to .82) rather than attitudes (beta = .17 to .39) exerted a more powerful influence on nurses' decisions not to resuscitate.

    2015-01-01

    Background:Hemorrhagic shock (HS) results in myocardial contractile dysfunction.Studies showed that 17β-estradiol protects the myocardium against contractile dysfunction.The study investigated the cardioprotective effects of treatment with 17β-estradiol before resuscitation following 1 h of HS and resuscitation.Methods:Male Sprague-Dawley rats were assigned to 2 sets of experimental protocols:Ex vivo and in vivo treatment and resuscitation.Each set had three experimental groups (n =6 per group):Normotensive (N),HS and resuscitation (HS-R) and HS rats treated with 17β-estradiol (E) and resuscitated (HS-E-R).Rats were hemorrhaged over 60-min to reach a mean arterial blood pressure of 40 mmHg.In the ex vivo group,hearts were resuscitated by perfusion in the Langendorff system.In the 17β-estradiol treated group,17β-estradiol 280 μg/kg was added for the first 5 min.Cardiac function was measured.Left ventricular generated pressure (LVGP) and +dP/dt were calculated.In the in vivo group,rats were treated with 17β-estradiol 280 μg/kg s.c.after 60-min HS.Resuscitation was performed in vivo by the reinfusion of the shed blood for 30-min to restore normotension.Results:Treatment with 17β-estradiol before resuscitation in ex vivo treated and resuscitated isolated hearts and in the in vivo treated and resuscitated rats following HS improved myocardial contractile function.In the in vivo treated group,LVGP and +dP/dt max were significantly higher in 17β-estradiol treated rats compared to the untreated group (LVGP 136.40 ± 6.61 compared to 47.58 ± 17.55,and +dP/dt 661.85 ± 49.88 compared to 88.18 ± 0.85).Treatment with 17β-estradiol improved LVGP following HS.Conclusions:The results indicate that treatment with 17β-estradiol before resuscitation following HS protects the myocardium against dysfunction.

    2012-02-01

    Physiological investigations of snakes have established the importance of heart position and pulmonary structure in contexts of gravity effects on blood circulation. Here we investigate morphological correlates of cardiopulmonary physiology in contexts related to ecology, behavior and evolution. We analyze data for heart position and length of vascular lung in 154 species of snakes that exhibit a broad range of characteristic behaviors and habitat associations. We construct a composite phylogeny for these species, and we codify gravitational stress according to species habitat and behavior. We use conventional regression and phylogenetically independent contrasts to evaluate whether trait diversity is correlated with gravitational habitat related to evolutionary transitions within the composite tree topology. We demonstrate that snake species living in arboreal habitats, or which express strongly climbing behaviors, possess relatively short blood columns between the heart and the head, as well as relatively short vascular lungs, compared to terrestrial species. Aquatic species, which experience little or no gravity stress in water, show the reverse - significantly longer heart-head distance and longer vascular lungs. These phylogenetic differences complement the results of physiological studies and are reflected in multiple habitat transitions during the evolutionary histories of these snake lineages, providing strong evidence that heart-to-head distance and length of vascular lung are co-adaptive cardiopulmonary features of snakes.

    Objective To evaluate surgical methods and results of extracardiac conduit total cavopulmonary anastomosis (ECTCPA) without cardiopulmonary bypass (CPB).Methods From May 2000 to April 2003, 11 patients with functional univentricle underwent off-pump EC-TCPA (noCPB group). Their postoperative outcome was retrospectively compared with a 17-patient group who underwent EC-TCPA with cardiopulmonary bypass (CPB group) over a concurrent time period.Results There was 1 operative death in no-CPB group and 2 in CPB group; early postoperative hemodynamics appeared to significantly improve in no-CPB group. Blood and platelet transfusions decreased and blood plasma transfusion significantly lowered in no-CPB group compared with CPB group (P = 0.036). Postoperative courses of patients in no-CPB group were smooth and event free, and extubation time was substantially short. Intensive cares unit stay (P=0.04) and hospital stay (P= 0.02) postoperation were significantly shorter, hospital costs were significantly reduced (P= 0.004) in no-CPB group compared with CPB group.Conclusions EC-TCPA without use of CPB is not a difficult procedure; the procedure results in improvement in postoperative hemodynamics, and decreased use of blood and blood products. It is a more efficient operation with more short recovery time and reduced hospital stay.

    Full Text Available Abstract Background Hemodynamic function may be depressed in the early postoperative stages after cardiac surgery. The aim of this study was the analysis of the myocardial contractility in neonates after cardiopulmonary bypass (CPB and mild hypothermia. Methods Three indices of left ventricular myocardial contractile function (dP/dt, (dP/dt/P, and wall thickening were studied up to 6 hours after CPB in neonatal piglets (CPB group; n = 4. The contractility data were analysed and then compared to the data of newborn piglets who also underwent median thoracotomy and instrumentation for the same time intervals but without CPB (non-CPB group; n = 3. Results Left ventricular dP/dtmax and (dP/dtmax/P remained stable in CPB group, while dP/dtmax decreased in non-CPB group 5 hours postoperatively (1761 ± 205 mmHg/s at baseline vs. 1170 ± 205 mmHg/s after 5 h; p max and (dP/dtmax/P there were no statistically significant differences between the two groups. Comparably, although myocardial thickening decreased in the non-CPB group the differences between the two groups were not statistically significant. Conclusions The myocardial contractile function in survived neonatal piglets remained stable 6 hours after cardiopulmonary bypass and mild hypothermia probably due to regional hypercontractility.

  14. Cardiopulmonary Circuit Models for Predicting Injury to the Heart

    2004-11-01

    Circuit models have been used extensively in physiology to describe cardiopulmonary function. Such models are being used in the DARPA Virtual Soldier (VS) Project* to predict the response to injury or physiological stress. The most complex model consists of systemic circulation, pulmonary circulation, and a four-chamber heart sub-model. This model also includes baroreceptor feedback, airway mechanics, gas exchange, and pleural pressure influence on the circulation. As part of the VS Project, Oak Ridge National Laboratory has been evaluating various cardiopulmonary circuit models for predicting the effects of injury to the heart. We describe, from a physicist's perspective, the concept of building circuit models, discuss both unstressed and stressed models, and show how the stressed models are used to predict effects of specific wounds. *This work was supported by a grant from the DARPA, executed by the U.S. Army Medical Research and Materiel Command/TATRC Cooperative Agreement, Contract # W81XWH-04-2-0012.

  1. Comparison of the T-piece resuscitator with other neonatal manual ventilation devices: A qualitative review.

    LENUS (Irish Health Repository)

    2012-01-31

    AIM: To review the literature surrounding various aspects of T-piece resuscitator use, with particular emphasis on the evidence comparing the device to other manual ventilation devices in neonatal resuscitation. DATA SOURCES: The Medline, EMBASE, Cochrane databases were searched in April 2011. Ongoing trials were identified using www.clinicaltrials.gov and www.controlled-trials.com. Additional studies from reference lists of eligible articles were considered. All studies including T-piece resuscitator use were eligible for inclusion. RESULTS: Thirty studies were included. There were two randomised controlled trials in newborn infants comparing the devices, one of which addressed short and intermediate term morbidity and mortality outcomes and found no difference between the T-piece resuscitator and self inflating bag. From manikin studies, advantages to the T-piece resuscitator include the delivery of inflating pressures closer to predetermined target pressures with least variation, the ability to provide prolonged inflation breaths and more consistent tidal volumes. Disadvantages include a technically more difficult setup, more time required to adjust pressures during resuscitation, a larger mask leak and less ability to detect changes in compliance. CONCLUSIONS: There is a need for appropriately designed randomised controlled trials in neonates to highlight the efficacy of one device over another. Until these are performed, healthcare providers should be appropriately trained in the use of the device available in their departments, and be aware of its own limitations.

    We investigated the relation between left ventricular dysfunction and myocardial edema in dogs with heartworm (Dirofilaria immitis) infection that were undergoing cardiopulmonary bypass. Dogs with and without D immitis were anesthetized by continuous thiopental infusion and were mechanically ventilated. Sonomicrometry crystals were placed on the long and short axes of the left ventricle, and a Millar pressure transducer was placed in the left ventricular chamber. Pressure-volume loops were digitized and continuously recorded. Dogs with and without D immitis were placed on standard hypothermic cardiopulmonary bypass, with 1 hour of aortic cross-clamp. Wet-to-dry weight ratio corrected for residual blood volume was used to quantitate the volume of myocardial edema. Preload recruitable stroke work was used as a preload-independent index of systolic function. Tau, the isovolumic relaxation time constant, was determined to assess diastolic relaxation. Dogs with D immitis had increased baseline myocardial wet-to-dry weight ratio. After cardiopulmonary bypass, myocardial edema increased in all dogs. Acute edema attributable to cardiopulmonary bypass decreased preload recruitable stroke work in all dogs of both groups, and dogs with D immitis could not be weaned from cardiopulmonary bypass. Myocardial edema increased diastolic relaxation times (tau) in dogs with and without D immitis. We conclude that cardiopulmonary bypass and heartworm infection induce myocardial edema. This edema compromises left ventricular systolic and diastolic function making D immitis an important confounding factor in weaning dogs from cardiopulmonary bypass. PMID:7717590

    Because of their physical size and physiological immaturity, resuscitation of extremely very low birth weight premature infants is a big dilemma for neonatologists in any hospital. The resuscitation may present an additional challenge to the caregiver if it is undertaken in a remote community hospital with limited technical facilities and health personnel. We present the case of successful resuscitation of a 23-week-old premature infant, with a birth weight of 650 g, at Delma Island Community...

Material and methods: In-hospital cardiac arrest teams at our hospital were instructed to complete a questionnaire following every emergency call between July 2011 and June 2013. Data on all resuscitation attempts were collected and analyzed. Results: A total of 65 in-hospital resuscitations were recorded in 42 males (64.6% and 23 females (35.4% (mean age 72.0±14.3 years. A total of 54 (83.1% cardiac arrests were witnessed; seven (10.8% showed a shockable rhythm at the time of the first ECG. Resuscitation attempts lasted 29.3±41.3 minutes, and 4.1±3.1 mg epinephrine was given. Return of spontaneous circulation could be achieved in 38 patients (58.5%; 29 (44.6% survived the first day, 23 (35.4% the seventh day, and 15 patients (23.1% were discharged alive. Significantly more in-hospital resuscitations were obtained for those performed during non-regular working hours (P<0.001, with higher neuron-specific enolase levels at 72 hours after resuscitation during nonregular working hours (P=0.04. Patients who were discharged alive were significantly younger (P=0.01, presented more often with an initial shockable rhythm (P=0.04, and had a shorter duration of resuscitation (P<0.001 with the need of a lower dose of epinephrine (P<0.001. Discussion: Survival rates following in-hospital resuscitation were poor at any time, but appear to depend less on time-dependent effects of the quality of resuscitation and more on time-dependent effects of recognition of cardiac arrests

    The inv/inv mouse carries an insertional mutation in the inversin gene, (inv, for inversion of embryonic turning). Previously it had been reported that almost 100% of the homozygous offspring (inv/inv) were characterized by situs inversus totalis. In this report we identify the spectrum of cardiopulmonary anatomical abnormalities in inv/inv mice surviving to birth to determine whether the abnormalities seen are of the categories classically associated with human situs abnormalities. Stillborn mice, offspring that died unexpectedly (within 48 hr after birth), and neonates with phenotypic characteristics of situs inversus (right-sided stomachs, growth failure or jaundice) were processed for standard histological examination. Of 173 offspring, 34 (20%) neonates (11 stillborn, 9 unexpected deaths, and 14 mice with situs inversus phenotype) were examined, 27 of which were genotyped to be inv/inv. Interestingly, three inv/inv mice (11%) were found to have situs solitus. Twenty-four had situs inversus with normal, mirror-image cardiac anatomy (dextrocardia with atrioventricular concordance, ventriculoarterial concordance and a right aortic arch). The overall incidence of cardiovascular anomalies observed was 10 out of 27 (37%). The most frequent severe malformation, identified in 3 out of 27 animals, was a complex consisting of pulmonary infundibular stenosis/atresia with absence of pulmonary valve tissue and a ventricular septal defect. The pulmonary phenotype in inv/inv mice was situs inversus with occasional minor lobar abnormalities. We conclude that 1) cardiopulmonary malformations in inv/inv mice are not rare (37%), 2) the cardiopulmonary malformations observed in inv/inv specimens are not of the spectrum typically associated with human heterotaxia. In particular, inv/inv mice have a propensity for defects in the development of the right ventricular outflow tract and the interventricular septum, and 3) approximately one out of ten inv/inv mice is born with situs

    Background Despite recovery of hemodynamics by fluid resuscitation after hemorrhage, development of the systemic inflammatory response and multiple organ dysfunction syndromes can nonetheless lead to death. Minocycline and doxycycline are tetracycline derivatives that are protective in models of hypoxic, ischemic and oxidative stress. Our Aim was to determine whether minocycline and doxycycline protect liver and kidney and improve survival in a mouse model of hemorrhagic shock and resuscitation. Methods Mice were hemorrhaged to 30 mm Hg for 3 h and then resuscitated with shed blood followed by half the shed volume of lactated Ringer's solution containing tetracycline (10 mg/kg), minocycline (10 mg/kg), doxycycline (5 mg/kg) or vehicle. For pre-plus post-treatment, drugs were administered intraperitoneally prior to hemorrhage followed by second equal dose in Ringer's solution after blood resuscitation. Blood and tissue were harvested after 6 h. Results Serum alanine aminotransferase (ALT) increased to 1988 and 1878 U/L after post-treatment with vehicle and tetracycline, respectively, whereas minocycline and doxycycline post-treatment decreased ALT to 857 and 863 U/L. Pre-plus post-treatment with minocycline and doxycycline also decreased ALT to 849 and 834 U/L. After vehicle, blood creatinine increased to 279 μM, which minocycline and doxycycline post-treatment decreased to 118 and 112 μM. Minocycline and doxycycline pre- plus post-treatment decreased creatinine similarly. Minocycline and doxycycline also decreased necrosis and apoptosis in liver and apoptosis in both liver and kidney, the latter assessed by TUNEL and caspase-3 activation. Lastly after 4.5 h of hemorrhage followed by resuscitation, minocycline and doxycycline (but not tetracycline) post-treatment improved 1-week survival from 38%(vehicle) to 69% and 67%, respectively. Conclusion Minocycline and doxycycline were similarly protective when given before as after blood resuscitation and might therefore

    Over the past decade, simulation-based education has emerged as a new and exciting adjunct to traditional bedside teaching and learning. Simulation-based education seems particularly relevant to emergency medicine training where residents have to master a very broad skill set, and may not have sufficient real clinical opportunities to achieve competence in each and every skill. In 2006, the Emergency Medicine program at Queen's University set out to enhance our core curriculum by developing and implementing a series of simulation-based teaching sessions with a focus on resuscitative care. The sessions were developed in such as way as to satisfy the four conditions associated with optimum learning and improvement of performance; appropriate difficulty of skill, repetitive practice, motivation, and immediate feedback. The content of the sessions was determined with consideration of the national training requirements set out by the Royal College of Physicians & Surgeons of Canada. Sessions were introduced in a stepwise fashion, starting with a cardiac resuscitation series based on the AHA ACLS guidelines, and leading up to a more advanced resuscitation series as staff became more adept at teaching with simulation, and as residents became more comfortable with this style of learning. The result is a longitudinal resuscitation curriculum that begins with fundamental skills of resuscitation and crisis resource management (CRM) in the first 2 years of residency and progresses through increasingly complex resuscitation cases where senior residents are expected to play a leadership role. This paper documents how we developed, implemented, and evaluated this resuscitation-based simulation curriculum for Emergency Medicine postgraduate trainees, with discussion of some of the challenges encountered.

    Background Seventeen million births occur in China each year.Neonatal mortality is the leading cause of under 5-year-old child deaths,and intrapartum-related injury accounts for much of mental retardation in young children.The Chinese Ministry of Health sought to improve infant and child survival through a nationwide initiative to have at least one person trained in neonatal resuscitation at every birth.The aim of the current study was to evaluate the impact of China Neonatal Resuscitation Program (NRP) on policy and infrastructure changes and its effectiveness in decreasing the incidence of mortality among newborn infants.Methods The Chinese NRP incorporated policy change,professional education,and creation of a sustainable health system infrastructure for resuscitation.Multidisciplinary teams from all 31 provinces and municipal states disseminated NRP in a train-the-trainer cascade.The intervention targeted 20 provinces with high neonatal mortality and programs to reduce maternal mortality.Program evaluation data came from 322 representative hospitals in those provinces.Results Changes in policy permitted midwives to initiate resuscitation and required resuscitation training for licensure.From 2004 through 2009 more than 110659 professionals received NRP training in the 20 target provinces,with 94% of delivery facilities and 99% of counties reached.Intrapartum-related deaths in the delivery room decreased from 7.5 to 3.4per 10000 from 2003 to 2008,and the incidence of Apgar ≤7 at 1 minute decreased from 6.3% to 2.9%.Conclusions The Chinese NRP achieved policy changes promoting resuscitation,trained large numbers of professionals,and contributed to reduction in delivery room mortality.Improved adherence to the resuscitation algorithm,extension of training to the township level,and coverage of births now occurring outside health facilities can further increase the number of lives saved.

    This study was designed to examine the results of emergency room resuscitative thoracotomy (ERRT) and to formulate cost-effective indications for this procedure. A retrospective study was performed of 28 patients who had ERRT at St. Elizabeth Hospital Medical Center, Youngstown, Ohio, during the 4 years from July 1985 through June 1989. The prognostic factors analyzed included mechanism and site of injury, signs of life (SOL), vital signs (VS), age, gender, and prehospital care. The overall survival rate of ERRT was 7% (2 of 28 patients). The survival rate was 18% (2 of 11 patients) with penetrating trauma, and 0% (none of 17 patients) with blunt trauma. The best survival rate was 66% in the subgroup of patients with penetrating trauma and SOL present at the scene and in the emergency room (ER), (two of three patients). Our observations were combined with those of 23 studies from the literature involving 2294 trauma patients who had ERRT. Using meta-analysis, the survival rate was 11% overall. Improved survival was noted for patients with penetrating trauma compared with patients with blunt trauma (14% vs. 2%, p ERRTs performed by 41% without decreasing the number of neurologically intact survivors.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:1464921

    Background Physicians are responsible for making decisions about the do not resuscitate (DNR) order of patients; however, most of them are faced with some uncertainty in decision making and ethical aspects. Moreover, there are differences on decision making related to the DNR order among physicians, which may be related to the different attitudes toward this issue. Considering the lack of information, this study was performed to investigate doctors’ attitude about DNR order for patients in their final phases of life. Methods In a descriptive–analytical study, 152 physicians were enrolled as quota sampling subjects from educational hospitals affiliated to the Kermanshah University of Medical Sciences. The tool used was a researcher-developed questionnaire. Data were analyzed using SPSS 16 software by descriptive and inferential statistics. Results The mean of attitude toward DNR was 3.22, for which the univariate t-test showed a significant positive attitude toward DNR (P=0.002); the mean of attitude number toward DNR was higher in physicians with higher education level (P=0.002). But this difference was not found in terms of age group, sex, and experiences in participating in DNR decisions. Conclusion Due to the positive attitude of doctors toward DNR orders and lack of identified guidance, clear guidelines that comply with the Iranian Islamic culture are necessary to be established. Implementing this directive requires comprehensive training to various groups, including patients, doctors, nurses, administrators, and policy makers of the health system. PMID:27418832

    After more than 30 yr of use, electroencephalographic (EEG) monitoring during cardiopulmonary bypass has not gained wide clinical acceptance. To assess its utility to predict central nervous system injury, two-channel recordings were made from 78 patients undergoing cardiopulmonary bypass and anesthetized with fentanyl/diazepam/enflurane. The perfusion regimen included the use of high pump flow, a bubble oxygenator, and no arterial tubing filter. Target values were 28-32 degrees C for the minimum rectal temperature, 60-80 mmHg for mean arterial pressure, and 20-25% for hematocrit. Eight descriptors of the Fourier power spectra of the EEG were calculated off-line, and outcome comparisons were made with the results from neuropsychological tests. Among 58 patients yielding complete data of acceptable quality, a statistically significant reduction in total power was observed from prebypass to postbypass, accompanied by an increase in the fractional power in the theta and beta frequency bands and in the spectral edge frequency. The shifts in total and theta power were weakly associated with short-term but not with long-term changes in neuropsychological scores. Nearly 40% of the patients' EEGs were corrupted with electrical noise at some time during bypass. In 15 patients selected for having high-quality recordings and no neuropsychological deficit, an extensive statistical analysis failed to reveal any consistent variation in the EEG descriptors with hypothermia. Under the conditions studied, it appears that for other than gross signal dropout, the strong background variability in the EEG makes it have little value for detecting harbingers of brain injury.

    AIM: To investigate the antioxidative potential of propofol (an intravenous anesthetic with a chemical structure similar to phenol-based free radical scavengers such as vitamin E) during cardiopulmonary bypass (CPB). METHODS:Thirty adult patients referred for elective cardiac procedure with CPB were included and randomly allocated to a nously for anesthesia maintenance, whereas those allocated to the control group received fentanyl 10 μg/kg intravenously and inhaled enflurane (1%-1.5 %). Blood samples were collected at 7 time points: before the start of CPB,at 30 and 60 min of CPB, at the conclusion of CPB, 10 min after the administration of protamine, and 12 and 24 h after the cessation of CPB. Plasma levels of free F2-isoprostanes (sensitive markers of free radicals production)and complement C5a were determined by mass-spectrometric assay and enzyme immunoassay, respectively. Neutrophil adhesion to endothelial cells was observed at x200 magnification under a light microscope. RESULTS:Levels of F2-isoprostanes, complement C5a and neutrophil adhesion rate increased significantly during and after CPB in both groups. There were significantly higher levels of F2-isoprostanes, C5a, and more neutrophils adhering to endothelial cells in the control group than those in the propofol group, respectively. CONCLUSION: Cardiopulmonary bypass is associated with a great production of damaging free radicals. Propofol may be beneficial both as an anesthetic and as a potent free radical scavenger in patients presenting pathologies associated with free radical reactions during CPB.

    Background Patients with repaired tetralogy of Fallot (TOF) usually experience progressive right ventricle (RV) dysfunction due to pulmonary regurgitation (PR). This could further worsen the cardiopulmonary function. This study aimed to compare the changes in patient exercise cardiopulmonary test and cardiac magnetic resonance imaging, and consider the implication of these changes. Methods Our study examined repaired TOF patients who underwent cardiopulmonary exercise test (CPET) to obtain maximal (peak oxygen consumption, peak VO2) and submaximal parameters (oxygen uptake efficiency plateau, oxygen uptake efficiency plateau (OUEP), and ratio of minute ventilation to carbon dioxide production, VE/VCO2 slope). Additionally, the hemodynamic status was assessed by using cardiac magnetic resonance. Criteria for exclusion included TOF patients with pulmonary atresia, atrioventricular septal defect, or absence of pulmonary valve syndrome. Results We enrolled 158 patients whose mean age at repair was 7.8 ± 9.1 years (range 0.1-49.2 years) and the mean patient age at CPET was 29.5 ± 12.2 years (range 7.0-57.0 years). Severe PR (PR fraction ≥ 40%) in 53 patients, moderate in 55, and mild (PR fraction 163 ml/m2. The mean left ventricular ejection fraction (LVEF) was 63 ± 8%, left ventricular end-diastolic volume index (LVEDVi) was 65 ± 12 ml/m2, and LVESVi was 25 ± 14 ml/m2. CPET revealed significantly decreased peak VO2 (68.5 ± 14.4% of predicted), and fair OUEP (90.3 ± 14.1% of predicted) and VE/VCO2 slope (27.1 ± 5.3). PR fraction and age at repair were negatively correlated with maximal and submaximal exercise indicators (peak VO2 and OUEP). Left ventricular (LV) function and size were positively correlated with peak VO2 and OUEP. Conclusions The results of CPET showed that patients with repaired TOF had a low maximal exercise capacity (peak VO2), but a fair submaximal exercise capacity (OUEP and VE/VCO2 slope), suggesting limited exercise capability in high

    Full Text Available Abstract Background Training of lay first responder personnel situated closer to the potential victims than medical professionals is a strategy potentially capable of shortening the interval between collapse and start of cardiopulmonary resuscitation (CPR in cases of out-of-hospital cardiac arrest. In this study we trained lay first responders personnel in basic life support (BLS and defibrillation for cases of cardiac arrest and suspected acute myocardial infarction (AMI. Methods Forty-two lay first responders living in remote areas or working in industries in the island community of Austevoll, Western Norway, were trained in CPR and defibrillation. We placed particular emphasis on the first responders being able to defibrillate a primary ventricular fibrillation (PVF in patients with AMI. The trainees were organised in four teams to attend victims of AMI and cardiac arrest while awaiting the arrival of the community emergency medical services. The purpose of the study was to find out whether the teams were able to function during the five-year study project, and to examine whether lives could be saved. The first responders completed questionnaires each year on their experiences of participation. Data on the medical actions of the teams were also collected. Results By the end of the project all groups were functioning. The questionnaires evidenced a reasonable degree of motivation and self-evaluated competence in both types of group organisation, but in spite of this attrition effects in the first responders were considerable. The first responders were called out on 24 occasions, for a total of 17 patients. During the study period no case of PVF occurred after the arrival of the first responders, and the number of AMIs was very low, strongly deviating from what was anticipated. No lives were saved by the project. Conclusions The teams were sustained for almost five years without any significant deterioration of self-reported stress or mastering

    Secondary intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) are closely related to fluid resuscitation. IAH causes major deterioration of the cardiac function by affecting preload, contractility and afterload. The aim of this review is to discuss the different interactions between IAH, ACS and resuscitation, and to explore a new hypothesis with regard to damage control resuscitation, permissive hypotension and global increased permeability syndrome. Review of the relevant literature via PubMed search. The recognition of the association between the development of ACS and resuscitation urged the need for new approach in traumatic shock management. Over a decade after wide spread application of damage control surgery damage control resuscitation was developed. DCR differs from previous resuscitation approaches by attempting an earlier and more aggressive correction of coagulopathy, as well as metabolic derangements like acidosis and hypothermia, often referred to as the 'deadly triad' or the 'bloody vicious cycle'. Permissive hypotension involves keeping the blood pressure low enough to avoid exacerbating uncontrolled haemorrhage while maintaining perfusion to vital end organs. The potential detrimental mechanisms of early, aggressive crystalloid resuscitation have been described. Limitation of fluid intake by using colloids, hypertonic saline (HTS) or hyperoncotic albumin solutions have been associated with favourable effects. HTS allows not only for rapid restoration of circulating intravascular volume with less administered fluid, but also attenuates post-injury oedema at the microcirculatory level and may improve microvascular perfusion. Capillary leak represents the maladaptive, often excessive, and undesirable loss of fluid and electrolytes with or without protein into the interstitium that generates oedema. The global increased permeability syndrome (GIPS) has been articulated in patients with persistent systemic inflammation failing

In recent years, there are many researches about cardiac arrest and cardiopulmonary resuscitation and have achieved some progress, however, it they are not enough, the explanation of the pathophysiological changes in different types of cardiac arrest is not very comprehensive, and the effective drugs and treatments which will benefit cardiac arrest also still need further study. The successed establishment of different types of animal model of cardiac arrest and resuscitation that similar to human is not only the important foundation and research approach for further study of the pathophysiology in various tapes of cardiac arrest, but also the necessary means for the research of much more effective drugs and treatment which will benefit the patients who suffered cardiac arrest. This paper mainly focused on the different research methods in various types of cardiac arrest animal model in rabbits.

  1. Utilising cardiopulmonary bypass for cancer surgery. Malignancy-induced protein C deficiency and thrombophilia.

    LENUS (Irish Health Repository)

    Marshall, C

    2012-02-03

    Cardiopulmonary bypass has evolved over the last 30 years. It is an important tool for the cardiac surgeon today and also has applications in non-cardiac operations such as surgery to extract tumours. Such patients undergoing surgery for cancer may be at an increased risk of a thromboembolic event post surgery, due to disturbances in the normal clotting pathway leading to hypercoagulability. One such disturbance is malignancy-induced Protein C deficiency. A deficiency of Protein C can cause hypercoagulabitity. Recent studies have examined cardiopulmonary bypass and inherited Protein C deficiency. However, surgery for cancer patients with a malignancy-induced Protein C deficiency involving cardiopulmonary bypass has not been reported. Surgery using CPB in these patients may result in increased morbidity and mortality. The objective of this article is to review the literature in order to discuss the occurrence, the aetiology and possible management of cancer patients with malignancy-induced Protein C deficiencies that require cardiopulmonary bypass for their surgery.

    Introduction Cardiopulmonary bypass causes a series of inflammatory events that have adverse effects on the outcome. The release of cytokines, including interleukins, plays a key role in the pathophysiology of the process. Simultaneously, cessation of ventilation and pulmonary blood flow contribute to ischaemia–reperfusion injury in the lungs when reperfusion is maintained. Collapse of the lungs during cardiopulmonary bypass leads to postoperative atelectasis, which correlates with the amount...

    Giant hiatus hernia with or without intrathoracic gastric volvulus often presents with symptoms suggestive of both cardiac and pulmonary compression. Cardiopulmonary impairment may be reversible in these patients by laparoscopic crural repair and fundoplication as shown in this case report. Cardiac magnetic resonance and the cardiopulmonary exercise test may help selecting patients for surgery. These preliminary findings led us to start a prospective study using this multimodality diagnostic approach. PMID:26210719

    Advanced renal cell carcinoma (RCC) resection has important anesthetic management implications, particularly when tumor extends, suprahepatic, into the right atrium. Use of transesophageal echocardiogram (TEE) is essential in identifying tumor extension and guiding resection. Latest surgical approach avoids venovenous and cardiopulmonary bypass yet requires special precautions and interventions on the anesthesiologist's part. We present a case of Level IV RCC resected without cardiopulmonary bypass and salvaged by TEE guidance and detection of residual intracardiac tumor. PMID:27716710

    Background Acute kidney injury (AKI) is associated with poor prognosis after cardiopulmonary bypass. The aim of this retrospective study was to investigate whether stent implantation before cardiopulmonary bypass has beneficial effect on development of AKI in renal artery stenosis (RAS) patients.Methods In this retrospective study, patients with abnormal baseline serum creatinine (SCr, >106 μmol/L) were not included. Included patients (n=69) were divided into two groups. Group 1 included 31 RAS patients receiving no stent implantation before cardiopulmonary bypass. Group 2 included 38 RAS patients having received stent implantation just before cardiopulmonary bypass. To assess AKI after cardiopulmonary bypass, serum urea nitrogen, SCr and creatinine clearance were recorded at baseline, at the end of operation, during the first and second postoperative 24 hours.Results Baseline characteristics were similar between groups. Serum urea nitrogen, SCr, creatinine clearance before and after cardiopulmonary bypass were also similar class groups. Incidence of AKI in group 1 was not significantly different from group 2. In group 1, AKI defined by RIFLE between occurred in 7 (22.6%) patients: 5 (16.1%) with RIFLE-R,2 (6.5%) with RIFLE-I, and no patients with RIFLE-F. In group 2, 10 patients (26.3%) had an episode of AKI during hospitalization: 6 (15.8%) had RIFLE-R, 4 (10.5%) had RIFLE-I, and no patients had RIFLE-F.Conclusions There are no data suggesting that it is necessary to stent RAS patients with normal SCr before cardiopulmonary bypass. However, it cannot be concluded that RAS is not associated with AKI after cardiopulmonary bypass.

  8. The Beneficial Effect of Direct Peritoneal Resuscitation on Septic Shock in Rats

    Full Text Available The high mortality associated with conventionally resuscitated septic shock and the subsequent multiple-organ failure remain a very significant and costly clinical problem. Conventional simple intravenous resuscitation (CR from septic shock often fails to restore the progressive splanchnic vasoconstriction and hypoperfusion, and fails to reverse gut-derived systemic inflammatory response and fluid sequestration. Numerous interventions have been used to protect organ systems and cellular viability from the lethal injury accompanying hypoperfusion and ischemia but none of these efforts have been sufficient to halt or reverse the main course of the pathophysiology noted with conventional resuscitated shock. Recently, some studies have found that in hemorrhagic shock, direct peritoneal resuscitation (DPR not only produces sustained hyperperfusion in viscera but also has immunomodulatory and anti-fluid sequestration effects. Although the etiology and pathogenesis of septic shock and hemorrhagic shock differ, both kinds of shock result in hypoperfusion of the intestines and other internal organs. In this paper, we seek to determine whether DPR has a similar therapeutic effect on septic shock/resuscitation.

    Early resuscitation of septic shock patients reduces the sepsis-related morbidity and mortality. The main goals of septic shock resuscitation include volemic expansion, maintenance of adequate tissue perfusion and oxygen delivery, guided by central venous pressure, mean arterial pressure, mixed or central venous oxygen saturation and arterial lactate levels. An aggressive fluid resuscitation, possibly in association with vasopressors, inotropes and red blood cell concentrate transfusion may be necessary to achieve those hemodynamic goals. Nonetheless, even though fluid administration is one of the most common interventions offered to critically ill patients, the most appropriate type of fluid to be used remains controversial. According to recently published clinical trials, crystalloid solutions seem to be the most appropriate type of fluids for initial resuscitation of septic shock patients. Balanced crystalloids have theoretical advantages over the classic solutions, but there is not enough evidence to indicate it as first-line treatment. Additionally, when large amounts of fluids are necessary to restore the hemodynamic stability, albumin solutions may be a safe and effective alternative. Hydroxyethyl starches solutions must be avoided in septic patients due to the increased risk of acute renal failure, increased need for renal replacement therapy and increased mortality. Our objective was to present a narrative review of the literature regarding the major types of fluids and their main drawbacks in the initial resuscitation of the septic shock patients.

    Objective: To investigate the therapeutic effect of cisapride on gastric injury following hemorrhagic shock resuscitation.Methods: 108 Wistar rats weighing (200 g±30 g) were randomly divided into a sham shock (SS) group (n=36), a hemorrhagic shock resuscitation (HS) group (n=36) and a hemorrhagic shock cisapride treated (HSC) group (n=36). Sampling at 1, 2 and 4 hours after resuscitation was done and 6 samples for each observation item were taken. The gastric blood flow volume was measured by isotope label biological microglobulin. Gastric pHi, gastric emptying, MDA and Na+-K+-ATPase of gastric mucosa were measured.Results: In the HSC group, the relative residual rate of gastric pigment decreased significantly, the gastric blood flow volume elevated; gastric pHi increased significantly at 2 hours; the level of mucosal MDA decreased at 4 hours, the activity of Na+-K+-ATPase increased and the lactic acid level in the portal vein decreased significantly compared to the HS group.Conclusions: After hemorrhagic shock resuscitation, cisapride contained the following functions,1) promoting gastric emptying, 2) increasing the blood flow of gastric blood flow volume and gastric pHi, 3) depressing the lactic acid concentration of the portal vein and improving MDA volume and Na+-K+ -ATPase activity of gastric mucosa. It suggests that after comple menting effective circulating blood volume for hemorrhagic shock resuscitation, early use of cisapride for gastric motility is helpful for an improvement of lasting ischemia and hypoxia in stomach.

    Full Text Available Background: Continued hemorrhage remains a major contributor of mortality in massively transfused patients and controversy regarding the optimal management exists although recently, the concept of hemostatic resuscitation, i.e., providing large amount of blood products to critically injured patients in an immediate and sustained manner as part of an early massive transfusion protocol has been introduced. The aim of the present review was to investigate the potential effect on survival of proactive administration of plasma and/or platelets (PLT in trauma patients with massive bleeding. Materials and Methods: English databases were searched for reports of trauma patients receiving massive transfusion (10 or more red blood cell (RBC within 24 hours or less from admission that tested the effects of administration of plasma and/or PLT in relation to RBC concentrates on survival from January 2005 to November 2010. Comparison between highest vs lowest blood product ratios and 30-day mortality was performed. Results: Sixteen studies encompassing 3,663 patients receiving high vs low ratios were included. This meta-analysis of the pooled results revealed a substantial statistical heterogeneity (I 2 = 58% and that the highest ratio of plasma and/or PLT or to RBC was associated with a significantly decreased mortality (OR: 0.49; 95% confidence interval: 0.43-0.57; P<0.0001 when compared with lowest ratio. Conclusion: Meta-analysis of 16 retrospective studies concerning massively transfused trauma patients confirms a significantly lower mortality in patients treated with the highest fresh frozen plasma (FFP and/or PLT ratio when compared with the lowest FFP and/or PLT ratio. However, optimal ranges of FFP: RBC and PLT : RBC should be established in randomized controlled trials.

    the same side as the stimulus, crossing of reflexes, to involve the other side, not occurring till later. As a rule, all reflexes return, and a short period of quiet follows. The anterior part of the cord again becomes irritable to strychnine, but succumbs to its action before the normal part. Spasms, of tonic, clonic, or mixed type, then appear, terminating in (a) death, (b) partial or (c) complete recovery. In partial recovery, disturbances of locomotion, such as walking in a circle, paralysis, dementia, loss of sight, hearing, and general intelligence, characterize the post-convulsive period. After complete recovery, there is a return to normal deportment. No gross lesions of the nervous system, other than a congested appearance of the previously anaemic area, were observed. Transection of the spinal cord stops the spasms below the level of section. Hemisection of the cord stops the spasms on the same side, below the level of section. Death, without any return of the reflexes after release of the cerebral arteries, has followed an occlusion of seven and one-half minutes. Respiration has returned after an occlusion of one hour. Five animals have recovered completely after an occlusion of seven minutes or more. Only one animal has recovered completely after an occlusion of fifteen minutes. No animal has recovered completely after an occlusion of twenty minutes. In Herzen's (26) resuscitation of an animal after several hours of cerebral anaemia, there must have been some anastomotic channels to the brain. Mayer's (27) limit of ten to fifteen minutes of cerebral anaemia, beyond which resuscitation is not practicable, is close to the correct one. It appears to us that, in cases of resuscitation two hours after cessation of the heart-beat, (Prus., loc.cit.) the auricles must have kept up a slow but, in some degree, an efficient movement of the blood through the brain. The truth of this suggestion might be tested by introducing some easily recognized, non

    An application of the KBSIM (Knowledge-Based SIMulation) system to the improved design of fluid resuscitation is described. The system integrates knowledge from three domains, viz. the pathophysiology of traumatized patients represented in a quantitative biodynamic model, the heuristics of fluid resuscitation of such patients as represented in 'production rules', and some 'metaknowledge' reflected in the design of a multi-window user interface. This technique of combining numerical simulation with symbolic reasoning has obvious advantages during the design process and in training, by giving the user a possibility to evaluate his measures by direct feedback from the system. This feature of the system to assist in evaluation of alternative resuscitation procedures should also be useful as a means for decision support. PMID:2060289

    Delayed clamping of the umbilical cord is recommended for term and preterm infants who do not require resuscitation. However, the approach to the newly born infant with signs of fetal compromise, prematurity and extremely low birthweight, or prolonged apnea is less clear. Human and experimental animal data show that delaying the clamping of the umbilical cord until after the onset of respirations promotes cardiovascular stability in the minutes immediately after birth. Rather than regarding delayed cord clamping as a fixed time period before resuscitation begins, a more physiologic concept of transition at birth should encompass the relative timing of onset of respirations and cord occlusion. Further research to explore the potential benefits of resuscitation with the cord intact is needed. PMID:24055300

    To assess the willingness of physicians and nurses with training in basic cardiac life support to provide mouth-to-mouth resuscitation in both hospital and out-of-hospital settings, we surveyed all attendees at a monthly advanced life support course over a 1-year period. Of 622 attendees, 379 (61%) responded to our survey describing a variety of cardiac arrest scenarios. Less than half of the participants surveyed were willing to do mouth-to-mouth resuscitation on an unknown adult, male or fe...

    The Court of Appeal has ruled that patients and their relatives have the right to be consulted prior to a 'do not attempt resuscitation' notice being placed on file by a health professional. Failing to do so would be in breach of the patient's right to respect for a private and family life under the European Convention of Human Rights, article 8. This article sets out the steps that district nurses must take to ensure that 'do not attempt resuscitation' notices placed on the file of their patients are lawful.

    A pulsatile pump driven by a coil spring, which was designed and constructed by us, is described in this report. It consists of two main parts, a disposable blood chamber and a driving section. The blood chamber has two leaflet valves and a piston, which is covered with two bellofram rolling diaphragms and moves into the housing to draw in and eject the blood. The driving section consists of three cams, an electric motor and a coil spring. The ejection force is wholly produced by the compressed coil spring and is transmitted to the piston in the blood chamber by a rod. This pump allows the ejection pressure, the beat rates, and the stroke volume all to be changed independently. The performance of the pump was tested by using a circulation model where the beat rate was adjusted from 30 to 250 bpm. The output subsequently increased from 0.8 l/min to 5.7 l/min and the stroke volume, from 20.4 ml to 36.7 ml. This new pump has been used for clinical cardiopulmonary bypasses in 24 patients of open heart surgery and the pressure traces during perfusion resembled those of the patients' own hearts.

    Full Text Available Background. In IPF, defects in lung mechanics and gas exchange manifest with exercise limitation due to dyspnea, the most prominent and disabling symptom. Aim. To evaluate the role of exercise testing through the 6MWT (6-minute walk test and CPET (cardiopulmonary exercise testing in the survival of patients with IPF. Methods. This is a prospective, observational study evaluating in 25 patients the relationship between exercise variables through both the 6MWT and CPET and survival. Results. By the end of the observational period 17 patients were alive (33% mortality. Observation ranged from 9 to 64 months. VE/VCO2 slope (slope of relation between minute ventilation and CO2 production, VO2 peak/kg (peak oxygen consumption/kg, VE/VCO2 ratio at anaerobic threshold, 6MWT distance, desaturation, and DLCO% were significant predictors of survival while VE/VCO2 slope and VO2 peak/kg had the strongest correlation with outcome. The optimal model for mortality risk estimation was VO2 peak/kg + DLCO% combined. Furthermore, VE/VCO2 slope and VO2 peak/kg were correlated with distance and desaturation during the 6MWT. Conclusion. The integration of oxygen consumption and diffusing capacity proved to be a reliable predictor of survival because both variables reflect major underlying physiologic determinants of exercise limitation.
