resuscitation

摘要： Background:Anoxic brain injuries represent the main determinant of poor outcome after cardiac arrest(CA).Large animal models have been described to investigate new treatments during CA and post-resuscitation phase,but a detailed model that includes extensive neuromonitoring is lacking.Method:Before an electrically-induced 10-minute CA and resuscitation,46 adult pigs underwent neurosurgery for placement of a multifunctional probe(intracranial pressure or ICP,tissue oxygen tension or PbtO_(2) and cerebral temperature)and a bolt-based technique for the placement and securing of a regional blood flow probe and two sEEG electrodes;two modified cerebral microdialysis(CMD)probes were also inserted in the frontal lobes and accidental misplacement was prevented using a perforated head support.Result:42 animals underwent the CA procedure and 41 achieved the return of spontaneous circulation(ROSC).In 4 cases(8.6%)an adverse event took place during preparation,but only in two cases(4.3%)this was related to the neurosurgery.In 6 animals(13.3%)the minor complications that occurred resolved after probe repositioning.Conclusion:Herein we provide a detailed comprehensive neuromonitoring approach in a large animal model of CA that might help future research.

摘要： Abdominal distention after cardiopulmonary resuscitation(CPR)is a common phenomenon that presents in the emergency department.It is caused by a long period of bag-valve mask ventilation or esophageal intubation.However,a rare but life-threating diagnosis should be considered when distention progresses rapidly.Here,we reported a patient who developed a fever and abdominal pain that couldn’t be relieved by gastric decompression.

摘要： OBJECTIVES To assess the effect of vasopressin,steroid and epinephrine(VSE)combination therapy on return of spontan-eous circulation(ROSC)after in-hospital cardiac arrest(IHCA),and test the conclusiveness of evidence using trial sequential ana-lysis(TSA).METHODS The systematic search included PubMed,EMBASE,Scopus,and Cochrane Central Register of Controlled Trials.Randomized controlled trials(RCTs)that included adult patients with IHCA,with at least one group receiving combined VSE therapy were selected.Data was extracted independently by two reviewers.The main outcome of interest was ROSC.Other out-comes included survival to hospital discharge or survival to 30 and 90 days,with good neurological outcomes.RESULTS We included a total of three RCTs(n=869).Results showed that VSE combination therapy increased ROSC(risk ra-tio=1.41;95%CI:1.25-1.59)as compared to placebo.TSA demonstrated that the existing evidence is conclusive.This was also validated by the alpha-spending adjusted relative risk(1.32[1.16,1.49],P<0.0001).Other outcomes could not be meta-analysed due to differences in timeframe in the included studies.CONCLUSIONS VSE combination therapy administered in cardiopulmonary resuscitation led to improved rates of ROSC.Fu-ture trials of VSE therapy should evaluate survival to hospital discharge,neurological function and long-term survival.

摘要： Dear editor,Pulmonary thromboembolism(PTE)has become the third most lethal type of thrombotic disease in the world.[1]Thrombolysis has been advised for high-risk PTE patients,however due to its unique pathophysiology,which differs from other atherosclerotic diseases,this can still be a challenge for PTE patients.[2]We reported two cases with a high-risk of PTE that had the onset of or progressed to cardiac arrest(CA)during hospitalization and were successfully managed with cardiopulmonary resuscitation(CPR)combined with thrombolytic therapy.

摘要： For about a quarter of a century,monitoring lactate levels and/or lactate clearance has been an unquestionable cornerstone in sepsis management.The elevated lactate level appeared to be an independent predictor of mortality,and the consequent metabolic acidosis was thought to explain a number of pathophysiological changes seen in septic shock.Recent physiological and clinical findings seem to challenge the adverse role of lactic acidosis in sepsis.Evidence suggests that lactate levels are not necessarily directly proportional to either tissue or cellular hypoxia,and conversely,despite high lactate levels,increased peripheral tissue oxygen pressure can be measured in adult patients with septic shock.According to the most recent understanding of in vitro and in vivo evidence,the elevated lactate level in sepsis might be a normal reaction due to adrenergic stress with potential beneficial/protective physiological effects,as well.On the one hand,burning lactic may help fuel the body during critical illness,but on the other hand,with a slight drop in pH,the body may counteract certain deleterious changes during the dysregulated host response;reduce the chances of reperfusion myocardial injury,and improve tissue oxygenation by shifting the haemoglobin dissociation curve to the right.Understanding the pathophysiological process in sepsis resulting in elevated lactate levels may aid management in an emergency,medicine,and intensive care settings.With more in-depth physiological knowledge,physicians may inevitably surpass normalisation heuristics and deliver personalized rather than protocolised sepsis resuscitation.

摘要： Emerging evidence suggests that bone marrow-derived mesenchymal stem cell transplantation improves neurological function after cardiac arrest and cardiopulmonary resuscitation;however, the precise mechanisms remain unclear. This study aimed to investigate the effect of bone marrow-derived mesenchymal stem cell treatment on expression profiles of multiple cytokines in the brain after cardiac arrest and cardiopulmonary resuscitation. Cardiac arrest was induced in rats by asphyxia and cardiopulmonary resuscitation was initiated 6 minutes after cardiac arrest. One hour after successful cardiopulmonary resuscitation, rats were injected with either phosphate-buffered saline(control) or 1 × 10~6 bone marrow-derived mesenchymal stem cells via the tail vein. Serum S100 B levels were measured by enzyme-linked immunosorbent assay and neurological deficit scores were evaluated to assess brain damage at 3 days after cardiopulmonary resuscitation. Serum S100 B levels were remarkably decreased and neurological deficit scores were obviously improved in the mesenchymal stem cell group compared with the phosphate-buffered saline group. Brains were isolated from the rats and expression levels of 90 proteins were determined using a RayBio Rat Antibody Array, to investigate the cytokine profiles. Brain levels of the inflammatory mediators tumor necrosis factor-α, interferon-γ, macrophage inflammatory protein-1α, macrophage inflammatory protein-2, macrophage inflammatory protein-3α, macrophage-derived chemokine, and matrix metalloproteinase-2 were decreased ≥ 1.5-fold, while levels of the anti-inflammatory factor interleukin-10 were increased ≥ 1.5-fold in the mesenchymal stem cell group compared with the control group. Donor mesenchymal stem cells were detected by immunofluorescence to determine their distribution in the damaged brain, and were primarily observed in the cerebral cortex. These results indicate that bone marrow-derived mesenchymal stem cell transplantation attenuates brain damage induced by cardiac arrest and cardiopulmonary resuscitation, possibly via regulation of inflammatory mediators. This experimental protocol was approved by the Institutional Animal Care and Use Committee of Fujian Medical University, China in January 2016(approval No. 2016079).

摘要： Background: Both competitive and recreational sports are considered a positive practice that is good for human health and quality of life, so it is difficult to understand how young, energetic and apparently healthy people can die while playing their usual sports. When these events occur in elite athletes during monitored events, they normally receive considerable media attention. Objective: To describe the case of sudden death in a young professional athlete who was successfully aided and resuscitated outside our hospital, and to review the literature about sudden death in sports. Materials and Method: We searched for Sudden Death (according to the International Classification of Diseases (ICD-9 and ICD-10)) in our hospital but found no other relevant cases. We performed a literature search on the state of the art in sudden death (Google Scholar, PubMed, LILACS, Scielo and the Revista Española de Cardiología). Results: Although we observed that the prevalence of sudden death is not very high, it still represents a potentially avoidable event. An adequate medical examination prior to regular sporting practice can decrease the incidence of sudden death in athletes under the age of 35. Data available in the literature support medical check-ups that include history-taking, physical examination and electrocardiogram. The findings of this evaluation may also prompt further assessment (electrocardiograph, ergometry). Conclusions: We could not identify standard, obligatory guidelines for screening possible heart diseases causing cardiorespiratory failure and sudden death. As a measure for primary prevention, we propose a protocol for reducing the risk of sudden death in athletes.

摘要： Introduction: The experience of convulsions is full of myths in our socio-cultural context. Objectives: To determine the frequency of seizures, to identify community practices in the care of seizures and the death risk factors. Methods: We conducted a prospective, descriptive and analytical study between April and August 2015 in the pediatric ward of the Lagoon Mother and Child University Hospital Center (CHUMEL) of Cotonou. We included children aged from 1 month to 15 years old hospitalized for either febrile or non-febrile convulsions happened at home. Results: A total of 102 cases of convulsion were included, 11.3% of hospitalizations. These were mostly children under 5 years, 87/102 (85.3%). Traditional resuscitation procedures were performed on 81 children (79.4%). They consisted of the forced introduction of objects in the mouth in 46 cases (46.1%), the oral administration of various products in 39 cases (38.2%), the ocular instillation of products in 10 cases (9.8%). Nineteen bodily injuries were found. The lethality was 15.8%. The risk factors for death identified were the use of traditional healers and the delay in consultation. Conclusion: The high frequency of seizures, the severity of seizures, the harmful traditional practices performed, and the delay to consultation require to strengthen the education of the population.

摘要： Purposes: Hypofibrinogenemia is usually complicated with severe and massive upper gastrointestinal (GI) bleeding, especially in liver cirrhosis. In Japan, neither fibrinogen concentrate nor cryoprecipitate (CRYO) is available for cases of acquired hypofibrinogenemia to recover the hemostatic level of fibrinogen rapidly. We prepared and produced in-house CRYO from fresh frozen plasma, and compared mortality between pre-implementation and post-implementation of CRYO. Methods: We performed a retrospective cohort study of patients admitted to our single tertiary medical center with upper GI bleeding from January 2011 to December 2016. The observational control period was from January 2011 to February 2013. From March 2013 to December 2016, we implemented the transfusion of CRYO, which was prepared and produced in our hospital. Clinical outcomes were compared between the patients in the two periods. Patients: Eleven patients in the control period and 10 in the intervention period were eligible for analysis. Results: In-hospital mortality (55% vs. 20%, P = 0.238) and mortality within 24 hour after admission (27% vs. 0%, P = 0.246) tended to be lower in the intervention period than in the control period, although the patients had more severe coagulation on admission than those in the control period. The plasma fibrinogen level before the treatment of hemostasis in the intervention period was higher than that in the control period (80 ± 9 mg/dL vs. 127 ± 15 mg/dL, P Conclusion: Implementation of in-house CRYO transfusion may reduce the rate of mortality due to severe upper GI bleeding.
