ABSTRACT
Objective:To explore the independent risk factors of in-hospital cardiac arrest (IHCA) in critically ill patients and construct a nomogram model to predict the risk of IHCA based on the identified risk factors.Methods:Patients who were admitted to the intensive care units (ICUs) from 2008 to 2019 were retrospectively enrolled from the Medical Information Mart for Intensive Care -Ⅳ database. The patients were excluded if they (1) were younger than 18 years old, (2) had repeated ICU admission records, or (3) had an ICU stay shorter than 24 h. The patients were randomly divided into the training and internal validation cohorts (7 : 3). Univariate and multivariate logistic regression models were used to identify independent risk factors of IHCA, and a nomogram was constructed based on these independent risk factors. Calibration curve, receiver operating characteristic (ROC) curve, and decision curve analysis (DCA) were used to evaluate the nomogram model. Finally, the nomogram was externally validated using the emergency ICU collaborative research database.Results:A total of 41,951 critically ill patients were enrolled (training cohort, n=29 366; internal validation cohort, n=12 585). Multivariate analysis showed that myocardial infarction, pulmonary heart disease, cardiogenic shock, respiratory failure, acute kidney injury, respiratory rate, glucose, hematocrit, sodium, anion gap, vasoactive drug use, and invasive mechanical ventilation were independent risk factors of IHCA. Based on the above risk factors, a nomogram for predicting IHCA was constructed. The area under the ROC curve (AUC) of the nomogram was 0.817 (95% CI: 0.785–0.847). The calibration curve showed that the predicted and actual probabilities of the nomogram were consistent. Moreover, DCA showed that the nomogram had clinical benefits for predicting IHCA. In the internal validation cohort, the nomogram had a similar predictive value of IHCA (AUC=0.807, 95% CI: 0.760–0.862). In an external validation cohort of 87,626 critically ill patients, the nomogram had stable ability for predicting IHCA (AUC=0.804, 95% CI: 0.786–0.822). In addition, the nomogram also had predictive value for in-hospital mortality (AUC=0.818, 95% CI: 0.802-0.834). Conclusions:The nomogram is constructed based on identified independent risk factors, which has good predictive value for IHCA. Moreover, the performance of the nomogram in the external validation cohort is robust. The study findings may help clinicians to assess the risk of IHCA in critically ill patients.
ABSTRACT
Abstract The erector spinae plane (ESP) block is an interfascial block described in 2016 by Forero and collaborators, with wide clinical uses and benefits when it comes to analgesic control in different surgeries. This block consists of the application of local anesthetic (LA) in a deep plane over the transverse process, anterior to the erector spinae muscle in the anatomical site where dorsal and ventral branches of the spinal nerve roots are located. This review will cover its clinical uses according to different surgical models, the existing evidence and complications described to date.

ABSTRACT
Abstract Adult In-hospital Cardiac Arrest (IHCA) is defined as the loss of circulation of an in-patient. Following high-quality cardiopulmonary resuscitation (CPR), if the return of spontaneous circulation (ROSC) is achieved, the post-cardiac arrest syndrome develops (PCAS). This review is intended to discuss the current diagnosis and treatment of PCAS. To approach this topic, a bibliography search was conducted through direct digital access to the scientific literature published in English and Spanish between 2014 and 2020, in MedLine, SciELO, Embase and Cochrane. This search resulted in 248 articles from which original articles, systematic reviews, meta-analyses and clinical practice guidelines were selected for a total of 56 documents. The etiologies may be divided into 56% of in-hospital cardiac, and 44% of non-cardiac arrests. The incidence of this physiological collapse is up to 1.6 cases/1,000 patients admitted, and its frequency is higher in the intensive care units (ICU), with an overall survival rate of 13% at one year. The primary components of PCAS are brain injury, myocardial dysfunction and the persistence of the precipitating pathology. The mainstays for managing PCAS are the prevention of cardiac arrest, ventilation support, control of peri-cardiac arrest arrythmias, and interventions to optimize neurologic recovery. A knowledgeable healthcare staff in PCAS results in improved patient survival and future quality of life. Finally, there is clear need to do further research in the Latin American Population.
Resumen El paro cardiaco intrahospitalario en el adulto (IHCA) se define como el cese de circulación ocurrido dentro de las instalaciones hospitalarias. Después de la reanimación cardiopulmonar (RCP) de alta calidad, si se logra el retorno de circulación espontánea (ROSC), aparece entonces el síndrome posparo cardiaco (SPPC). En esta revisión se pretende presentar el estado actual del diagnóstico y tratamiento del SPPC. Para abordar este tema, se realizó una búsqueda bibliográfica mediante la consulta digital directa de la literatura científica publicada entre 2014 y 2020 en inglés y español recogida en las bases de datos MedLine, SciELO, Embase y Cochrane. La búsqueda inicial arrojó 248 artículos, de los cuales se eligieron artículos originales, revisiones sistemáticas, metaanálisis y guías de práctica clínica, para una selección final de 56 documentos. Las etiologías del paro cardiaco intrahospitalario se pueden dividir en cardiacas y no cardiacas, en el 56 % y 44 %, respectivamente. El colapso fisiológico tiene incidencias de hasta 1,6 casos/1.000 pacientes admitidos, y es más frecuente en las unidades de cuidado intensivo (UCI), con una tasa de supervivencia general de 1 año del 13 %. Los componentes principales del SPPC son la lesión cerebral, la disfunción miocárdica y la persistencia de la patología precipitante. Los pilares del manejo del SPPC son la prevención del paro cardiaco, soporte ventilatorio, control de arritmias periparo cardiaco y las intervenciones para optimizar la recuperación neurológica. El conocimiento del SPPC por parte del personal de la salud ofrece mejor sobrevida y futura calidad de vida a los pacientes. Finalmente, se resalta la clara necesidad de ahondar en mayores investigaciones en la población latinoamericana.

Objective:To establish early warning indicators for Chinese nurses to recognize in-hospital cardiac arrest (IHCA) of adult inpatients.Methods:Computer retrieval of Chinese and English databases such as CNKI, Wanfang Database, VIP, National Medical Library of the United States PubMed Database, Web of Science, Embase Database of the Netherlands Medical Abstracts, Cochrane Library Database and other international guidelines collaboration network (GIN), National Institute for Health and Clinical Optimization (NICE), Scottish Intercollegiate Guidelines Network (SIGN), BMJ best clinical practice and other guidelines was performed. The retrieval time limit for respiratory and cardiac arrest early warning indicators or risk identification related content of the adult inpatient in the professional website was until June 30, 2020. After literature research and expert group analysis, the research group drew up an expert correspondence questionnaire, and selected 32 medical and nursing experts from Beijing, Tianjin, Jilin, Shandong, Shaanxi, Sichuan, Zhejiang and other grade three first-class general hospitals from July to September 2022. The Delphi method was used to conduct two rounds of expert correspondence, forming the final version of the early warning index of cardiac arrest in adult inpatients.Results:Five first-level indicators, 23 second-level indicators and 41 third-level indicators including vital signs, consciousness and pupils, postoperative blood drainage volume, lab results and other five aspects were initially formed. The effective response rates of the two rounds of expert correspondence were 100% (32/32) and 93.75% (30/32), respectively, the Kendall coordination coefficients W of the first round and the second round were 0.340 and 0.462, respectively, the expert authority coefficients Cr were 0.88 and 0.89, respectively, the mean value of importance assignment was 3.94-5.00, 4.07-5.00, and the coefficient of variation was 0-0.16, 0-0.14, with statistically significant differences (all P < 0.05). Finally, 5 primary indicators, 23 secondary indicators and 43 tertiary indicators were formed, including five aspects of vital signs, consciousness and pupils, postoperative blood drainage, lab results, symptoms and chief complaints. Conclusion:The expert consultation on the early warning indicators of IHCA for adult patients tends to be consistent and scientific, which is applicable to help nurses detect the changes of patients' condition as early as possible.
ABSTRACT
Objective:To verify the clinical value of the good outcome following attempted resuscitation (GO-FAR) score in predicting the neurological status of patients with in-hospital cardiac arrest (IHCA) in the Chinese population.Methods:The clinical data of patients with IHCA who were admitted to the Zigong Fourth People's Hospital from January 1 to December 31, 2020 were retrospectively analyzed. Used Glasgow-Pittsburgh cerebral performance category (CPC) score 1 point as the end point, the subjects were divided into 4 groups according to the score: ≤ 0 group, 1-8 group, 9-20 group and ≥ 21 group. Taken the group which GO-FAR score ≤ 0 as the reference group, the odds ratio ( OR) of the other three groups compared with this group was calculated. The receiver operator characteristic curve (ROC curve) was performed to evaluate the predictive value of the GO-FAR score in favorable neurological outcome. A calibration curve was drawn for the Hosmer-Lemeshow test to analyze the degree of calibration of the GO-FAR score for predicting good neurological outcome. Results:A total of 230 IHCA patients were enrolled in the study, including 130 males, aged 74 (65, 81) years old, and 23 case (10.0%) had good neurological prognosis. There were statistically significant differences in GO-FAR-related variables, including age, a normal neurological function on admitted, acute stroke, metastatic cancer, septicemia, medical noncardiac admission, hepatic insufficiency, hypotension, renal insufficiency or dialysis, respiratory insufficiency, pneumonia, etc (all P < 0.05). Taken the GO-FAR score ≤ 0 group as the reference group, the OR values of good neurological prognosis in the GO-FAR score 1-8 group were 0.54 [95% confidence interval (95% CI) was 0.17-1.53, P = 0.250], 9-20 group were 0.17 (95% CI was 0.02-0.67, P = 0.009) and ≥ 21 group were 0.25 (95% CI was 0.05-0.85, P = 0.025). The area under the ROC curve (AUC) of the GO-FAR score for predicting favorable neurological outcome in IHCA patients was 0.653 (95% CI was 0.529-0.777, P = 0.015) and there was no significant difference in Hosmer-Lemeshow test ( P = 0.311). All these suggested that there was no significant difference between the predicted value and the actual value. Conclusions:GO-FAR score can be applied to predict neurological prognosis of IHCA patients in Chinese population. It can help clinicians to predict the prognosis of cardio-pulmonary resuscitation (CPR) and propose critical recommendations in treatment for these patients or their families.
ABSTRACT
Objective To systematically evaluate the effects of mechanical chest compression (CC) combined with manual CC and single-manual CC on the outcome indexes of cardiopulmonary resuscitation (CPR) for patients with in-hospital cardiac arrest (IHCA). Methods The relevant publicly published literatures about the effects of mechanical CC combined with manual CC and single-manual CC on the outcome of CPR were searched by using the following Chinese keywords for retrieval: "cardiac arrest, asystole, sudden death, artificial recovery, artificial press, artificial CC, unarmed CPR, unarmed resuscitation, unarmed compressions, unarmed chest compressions, unarmed, artificial, resuscitation instrument, resuscitation machine, resuscitator, CPR, LUCAS, Autopulse, Thumper, MSCPR-1A"in databases such as China Biomedical Literature (CBM), VIP, Wanfang, and China National Knowledge Internet (CNKI) from their dates of foundation to March 11, 2019, and using the following key words in English "heart arrest, cardiac arrest, cardiopulmonary arrest, Cardiopulmonary Resuscitation, Resuscitation, Cardio-Pulmonary Resuscitation, CPR, compression, mechanical, automatic, automated, load distributing band, LBD, Autopulse, LUCAS" to retrieve all the published articles especially concerning the topics on the application effects of mechanical combined with manual CC for IHCA patients' CPR in the America National Library database (PubMed), Excerpta Medica (EMbase), Web of Science, and Cochrane Library from the establishment of the databases to March 11, 2019. The indexes of outcomes included return of spontaneous circulation (ROSC) rate, survival rate after hospital discharge and incidence of complications. The literatures were extracted independently by two reviewers, the qualities of the included randomized controlled trials (RCTs) were evaluated according to the Cochrane bias risk assessment tool, and the qualities of the included observational studies were evaluated according to the literature quality assessment form (NOS). Meta analysis was performed by using RevMan 5.3 software, and publication bias was assessed by using funnel plot. Results Twenty-one studies were enrolled, including 11 RCT articles and 10 observational studies; there were 2 005 participants. The results of this Meta-analysis showed that compared with manual CC, the ROSC rate and after discharge survival rate of IHCA patients were obviously higher in combined CC group [ROSC: odds ratio (OR) = 2.50, 95% confidence interval (95%CI) = 2.03-3.09, P < 0.000 01; discharge survival rate: OR = 2.71, 95%CI = 1.91-3.85, P < 0.000 01]; the incidence of complications of combined CC was lower than that in single manual CC (OR = 0.30, 95%CI = 0.13-0.68, P = 0.004). The funnel plots indicated that there was no apparent bias in the ROSC; because the enrolled studies were relatively few, it was difficult to evaluate the symmetrical characteristics of the funnel plots for discharge survival rate and the complication rate. Conclusions For IHCA patients, combined CC can improve ROSC, discharge survival rate, and reduce the occurrence of complications. It is suggested that during the actual rescue of IHCA patients, it is better to use combined CC, that is to say, manual CC should be adopted immediately in the early stage and then replace the mechanical CC device as soon as possible.
ABSTRACT
The Life Support Course for Nurses (LSCN) equips nurses with the resuscitation skills to be first responders in in-hospital cardiac arrests. Seventeen years after the initiation of the LSCN, a confidential cross-sectional Qualtrics™ survey was conducted in May 2016 on LSCN graduands to assess the following: confidence in nurse-initiated resuscitation post-LSCN; defibrillation experience and outcomes; and perceived barriers and usefulness of the LSCN. The majority of respondents reported that the course was useful and enhanced their confidence in resuscitation. Skills retention can be enhanced by organising frequent team-based resuscitation training. Resuscitation successes should be publicised to help overcome perceived barriers.
ABSTRACT
Objective To evaluate the prognostic value of the first documented rhythm in patients with in-hospital cardiac arrest.Methods The clinical data of 62 in-hospital cardiac arrest patients collected from May 2011 to April 2016 were reviewed.Multiple regression analysis was performed for determination of the factors relevant to ROSC.The patients were divided into defibrillative rhythm group [ventricular fibrillation (VF) /ventricular tachycardia (VT)] and non-defibrillative rhythm group [pulseless electrical activity (PEA) /asystole] according to the first documented rhythm after cardiac arrest.The differences in rate of restoration of spontaneous circulation,number of survival at hospital discharge and those discharged with favorable neurological outcome were compared between groups.Results Logistic regression analysis showed that non-defibrillative rhythm was related to low rate of ROSC.Rate of ROSC (x2 =6.90,P =0.01),number of survival at hospital discharge (x2 =10.49,P =0.00) and those discharged with favorable neurological outcome (x2 =14.70,P =0.00) were higher in the defibrillative rhythm group,while there was no difference in outcomes between the VF and VT groups.There was no difference in consequence found between the PEA and asystole groups.Conclusion Rate of restoration of spontaneous circulation,number of survival at hospital discharge and those discharged with favorable neurological consequence were higher with defibrillative initial rhythm.
ABSTRACT
OBJECTIVES: This study analyzed the incidence and characteristics of in-hospital cardiac arrest (IHCA) in Korea based on a sample group of patients that is representative of the population. METHODS: The incidence of IHCA in adults was extracted from HIRA-NIS-2009, a sample of all patients using medical services in Korea. IHCA patients were analyzed according to gender, age, type of medical institute, and classification under the 6th revision of the Korean Standard Classification of Diseases (KCD-6). In addition, to assess the differences arising from the size of medical institutes, the IHCA incidence was analyzed in relation to the number of inpatient beds. RESULTS: Based on the sample data, the total incidence of IHCA in Korea was found to be 2.46 per 1,000 admissions (95% confidence interval [CI], 2.37–2.55). A higher incidence was found among men at 3.18 (95% CI, 3.03–3.33), compared to women at 1.84 (95% CI, 1.74–1.94). The incidence of IHCA was also higher in hospitals that had more than 600 inpatients beds at 5.40 (95% CI, 5.16–5.66) in comparison to those that had less than 600 inpatients beds at 4.09 (95% CI, 3.76–4.36) (p < 0.001). By primary disease, the incidence was the highest for infectious diseases. CONCLUSIONS: We demonstrated that the IHCA incidence based on gender, age, diagnostic group, and number of beds could be analyzed using the insurance claim data from a national representative sample.

Objective To investigate the correlation between mechanical ventilation (MV) initiation time during cardiopulmonary resuscitation (CPR) and the prognosis of patients with in-hospital cardiac arrest (IHCA) in emergency . Methods Retrospective analysis of clinical records of patients with IHCA in emergency from January 2011 to April 2016 treated in Zhangye People's Hospital of Hexi University was performed. Patients with restoration of spontaneous circulation (ROSC) and were on MV with aged over 18 years were divided into early treated group (≤ 10 minutes) and later treated group (> 10 minutes) according to the initiation time of MV. Corneal reflex, pupillary reflex, pain-avoidance responses and motor response 24 hours after CPR, neurological function and cure rate of the two groups were analyzed. Results 210 patients were selected into our study including 130 males and 80 females (mean age: 60.24±13.17 years). There were no significant differences in gender, age, type of heart rate and etiological factor of cardiac arrest (CA) between the MV early stage group (124 cases) and the MV late stage group (86 cases). The restoration of corneal reflex, pupillary reflex, pain-avoidance responses, motor response and achievement ratio of CPR in early group were higher than those of later group (respectively, 59.68% vs. 31.40%, 59.68% vs. 31.40%, 54.84% vs. 24.42%, 54.84% vs. 24.42%, 70.16% vs. 51.16%, all P 0.05); The average hospitalized day of the early group was significantly shorter than that of the later group (days: 24.15±3.04 vs. 30.28±4.17, P < 0.01); Besides, the early group showed a higher survival rate at discharge and had more cases with neurologic level of grade 1-2 than those of the later group (Respectively, 41.94% vs. 26.74%, P < 0.05; 44.35% vs. 15.12%, P < 0.01). Conclusion Initiation MV on IHCA patients in the early stage of CPR (≤ 10 minutes) could help improve the hypoxic condition and prognosis of neurological function, and increase the achievement ratio of CPR.
ABSTRACT
Objective To investigate the usefulness of Utstein template to guide the assessment and study of cardiopulmonary resuscitation (CPR) in our medical practice because it has been popularized in many countries since 1991.Methods A prospective observational study using Utstein CPR registry form to evaluate the epidemiological features and outcomes of 511 patients resuscitated in the emergency department.Results Of 511 CPR patients registered,higher cardiac arrest rates were observed in the group of patients aged 40- 70 years. In 511 CPR patients registered,preexisting chronic diseases were common including cardiovascular diseases ( 190,37.2％ ) cerebrovascular diseases (48,9.4％ ) and respiratory diseases (39,7.6％ ).Of them,173 cardiac arrest patients (33.9％) had underlying cardiac causes,such as acute myocardial infarction (AMI) found in 109 (21.3％) patients,and ventricular fibrillation witnessed during first cardiac monitoring in eighty ( 15.7％ ) patients.The restoration of spontaneous circulation (ROSC) rate and survival rate at discharge of in - hospital cardiac arrest (IHCA) patients were 47.0％ and 13.5％respectively,but 16.7％ and 4.7％ respectively in the out - hospital cardiac arrest (OHCA) patients (P ＜0.01,both ). Conclusions This study indicated that the cardiovascular diseases, cerebrovascular diseases,and respiratory diseases were the most common preexisting chronic diseases found in cardiac arrest patients.Myocardial infarct,stroke and trauma were the most common precipitation causes of cardiac arrest in the recruited patients.The rates of ROSC and survival at discharge were significantly higher in statistics in patients with IHCA than those in ones with OHCA.
ABSTRACT
Objective To study the Hainan Utstein templates used for cardiac arrest and resuscitation registries to evaluate the epidemiological characteristics and outcomes of the patients with CPR by multi-center study. Methodsccording to the Utstein templates for cardiac arrest and CPR set by International Liaison Committee on resuscitation in 2004, a Hainan Utstein CPR registry chart was designed and a prospective descriptive study was carried out to evaluate the epidemiological characteristics, impact factors and outcomes of the patients with resuscitation attempt in emergency departments of thirteen hospitals in Hainan Island between January 2007 and December 2010.Results Of 1125 patients with cardiac arrest, male accounted for 73. 8％ and female was 26. 2％. The mean ( ± S. D) age of the cardiac arrest patients was 53.9 ± 13. 1 years old.Coronary heart diseases and hypertension were the most common preexisting chronic diseases in the studied patients. The ROSC rate and discharge rates after survival in 1125 patients with CPR were 23. 8％ and 7.4％ respectively. The ROSC rate and discharge rates after survival were 36. 3％ and 11.6％ in the in-hospital cardiac arrest (IHCA) group, respectively whereas 11.5％ and 3. 3％ in out-hospital cardiac arrest (OHCA) group. Of 188 patients with ventricular fibrillation/Pulseless ventricular tachycardia, the ROSC rate and discharge rate after survival were 58.0％and 21.8％,respectively. Of them, 448 (39. 8％ ) of the cardiac arrest patients had underlying cardiac causes, and the ROSC rate and discharge rate after survival were 36. 3％ and 11.5％ respectively in IHCA group whereas 11.6％ and 3. 3％ in OHCA group. The ROSC rate and discharge rate after survival were 69. 8％ and 7. 4％respectively in the tertiary hospitals whereas 30. 2％ and 7. 3％ in the secondary hospitals. Conclusions Patients experienced cardiac arrest were predominantly male. Coronary heart disease and hypertension were the two most common preexisting chronic diseases. The ROSC rate and discharge rate of patients with IHCA were higher than those with OHCA. ROSC rate and discharge rate after survival were higher in the ventriculat fibrillation/Pulseless ventricular tachycardia group than the other cardiac rhythms first witnessed groups. The time delayed of starting CPR after onset of cardiac arrest had a critical impact on survival and discharge rate in both IHCA and OHCA groups.
