Objectives: To investigate the current application status and implementation difficulties of extracorporeal cardiopulmonary resuscitation (ECPR) in children with sudden cardiac arrest. Methods: This cross-sectional survey was conducted in 35 hospitals. A Children's ECPR Information Questionnaire on the implementation status of ECPR technology (abbreviated as the questionnaire) was designed, to collect the data of 385 children treated with ECPR in the 35 hospitals. The survey extracted the information about development of ECPR, the maintenance of extracorporeal membrane oxygenation (ECMO) machine, the indication of ECPR, and the difficulties of implementation in China. These ECPR patients were grouped based on their age, the hospital location and level, to compare the survival rates after weaning and discharge. The statistical analysis used Chi-square test and one-way analysis of variance for the comparison between the groups, LSD method for post hoc testing, and Bonferroni method for pairwise comparison. Results: Of the 385 ECPR cases, 224 were males and 161 females. There were 185 (48.1%) survival cases after weaning and 157 (40.8%) after discharge. There were 324 children (84.2%) receiving ECPR for cardiac disease and 27 children (7.0%) for respiratory failure. The primary cause of death in ECPR patients was circulatory failure (82 cases, 35.9%), followed by brain failure (80 cases, 35.0%). The most common place of ECPR was intensive care unit (ICU) (278 cases, 72.2%); ECPR catheters were mostly inserted through incision (327 cases, 84.9%). There were 32 hospitals (91.4%) had established ECMO emergency teams, holding 125 ECMO machines in total. ECMO machines mainly located in ICU (89 pieces, 71.2%), and the majority of hospitals (32 units, 91.4%) did not have pre-charged loops. There were no statistically significant differences in the post-withdrawal and post-discharge survival rates of ECPR patients among different age groups, regions, and hospitals (all P>0.05). The top 5 difficulties in implementing ECPR in non-ICU environments were lack of ECMO machines (16 times), difficulty in placing CPR pipes (15 times), long time intervals between CPR and ECMO transfer (13 times), lack of conventional backup ECMO loops (10 times), and inability of ECMO emergency teams to quickly arrive at the site (5 times). Conclusion: ECPR has been gradually developed in the field of pediatric critical care in China, and needs to be further standardized. ECPR in non-ICU environment remains a challenge.

Targeted temperature management (TTM) has been partially applied in patients with restoration of spontaneous circulation (ROSC) after cardiac arrest (CA). In the 2020 American Heart Association (AHA) cardiopulmonary resuscitation (CPR) guidelines, TTM is used as advanced life support after ROSC for the treatment of patients with CPR. TTM has a protective effect on cardiac function after CA, but the specific mechanism of its protective effect on cardiac function remains unclear. In this paper, the basic experimental progress, clinical trial progress and development prospect of TTM on the protective mechanism of cardiac function after CA are reviewed.

The COVID-19 pandemic has resulted in significant challenges for the resuscitation of paediatric patients, especially for infants and children who are suspected or confirmed to be infected. Thus, the paediatric subcommittee of the Singapore Resuscitation and First Aid Council developed interim modifications to the current Singapore paediatric guidelines using extrapolated data from the available literature, local multidisciplinary expert consensus and institutional best practices. It is hoped that this it will provide a framework during the pandemic for improved outcomes in paediatric cardiac arrest patients in the local context, while taking into consideration the safety of all community first responders, medical frontline providers and healthcare workers.

PURPOSE: The purpose of this study was to examine the effects of an infant cardiopulmonary resuscitation (CPR) training program that applied the 5-step method on the knowledge, attitudes, and performance ability of nursing students in terms of enhancement and sustainability. METHODS: Sixty-one nursing students (28 in the experimental group and 33 in the control group) from D city participated in this study. Data were collected from April 25 to December 15, 2016. The experimental group and control group received infant CPR education using the 5-step method and the traditional method, respectively. The outcome variables were measured 3 times (pretest and posttest at 1 week and 6 months after training). RESULTS: There were significant differences in attitude (t=2.68, p=.009) and performance ability (t=4.56, p < .001) between the groups at 1 week after training, as well as in sustained performance ability at 6 months after training (F=6.76, p=.012). CONCLUSION: The 5-step method of infant CPR training was effective for improving performance ability in a sustained manner and promoting a positive attitude. Therefore, it is recommended that nursing students, as infant CPR novices, receive training using this effective method.

BACKGROUND: In breast surgery, regional anesthesia rather than primary anesthesia has been mainly used for postoperative analgesia. Serratus anterior plane block is a new method for ultrasound-guided thoracic wall block. It is less invasive and relatively safer than conventional regional anesthetic techniques. CASE: We report a case of breast surgery under serratus anterior plane block as primary anesthesia with monitored anesthesia for a 78-year-old patient with a medical history of cardiopulmonary resuscitation due to stress-induced cardiomyopathy caused by pneumonia. CONCLUSIONS: Serratus anterior plane block might be simple and effective technique for breast surgery when a lesion is located on lateral side.

OBJECTIVE: To evaluate the influence factors of different compression modes on restoration of spontaneous circulation (ROSC) and outcomes in patients with cardiac arrest. METHODS: Based on the national database of emergency cardiac arrest treatment, the clinical data of 517 patients with cardiac arrest admitted to 14 teaching hospitals in 7 provinces from July 2015 to July 2017 were enrolled. According to the way of compression, the patients were divided into mechanical compression group and hands-only compression group. The demographic data, resuscitation parameters [compression frequency, monitored ventilation frequency, duration of resuscitation, drug usage] and physiological parameters [end-expiratory partial pressure of carbon dioxide (P_ETCO₂), pulse oxygen saturation (SpO₂)] were collected. The ROSC rates and 24-hour, 7-day, 28-day survival rates were compared between the two groups. Multivariate Logistic regression model was used to analyze the influencing factors of ROSC according to whether the duration of resuscitation was longer than 60 minutes. RESULTS: Of 517 patients, 24 were excluded because of incomplete data. A total of 493 patients were enrolled in the analysis with 214 patients in the mechanical compression group, and 279 in the hands-only compression group. Compared with hands-only compression group, the patients in mechanical compression group had higher age, proportion of chronic obstructive pulmonary disease (COPD) and P_ETCO₂, fewer un-shockable rhythm, less compression rate, more epinephrine and sodium bicarbonate usage, and longer duration of cardiopulmonary resuscitation (CPR). Although the rate of ROSC in the mechanical compression group was higher than that in the hands-only compression group [36.9% (79/214) vs. 30.5% (85/279)], there was no significant difference in the rate of ROSC between the two groups [odds ratio (OR) = 1.10, 95% confidence interval (95%CI) = 0.68-1.76, P = 0.693], even after adjusted for con-variables by multivariate Logistic regression (OR = 1.21, 95%CI = 0.54-1.88, P = 0.054). Furthermore, 24-hour, 7-day, and 28-day survival rate also showed no significant difference in both univariate model and multivariate model. Comparisons of resuscitation parameters and physiological parameters between the two groups showed that when the duration of CPR < 60 minutes, the pressing frequency of the mechanical compression group was lower, ventilation frequency and adrenaline dosage were higher; and when the duration of CPR ≥ 60 minutes, the adrenaline dosage and P_ETCO₂ of the mechanical compression group were higher. Multivariate Logistic regression analysis showed that among patients with a duration of CPR < 60 minutes, un-shockable rhythm (OR = 0.29, 95%CI = 0.05-0.75, P = 0.015), compression rate > 120 times/min (OR = 0.39, 95%CI = 0.24-0.64, P < 0.001), ventilation frequency > 40 times/min (OR = 0.50, 95%CI = 0.31-0.84, P = 0.034) were independent risk factors for ROSC; while P_ETCO₂ ≥ 20 mmHg (1 mmHg = 0.133 kPa) was protective factor for ROSC (OR = 2.79, 95%CI = 1.88-4.49, P < 0.001). However, for patients with CPR duration ≥ 60 minutes, ≥ 65 years old (OR = 0.33, 95%CI = 0.15-0.67, P = 0.018), admission at night (OR = 0.74, 95%CI = 0.59-0.94, P = 0.035), un-shockable rhythm (OR = 0.38, 95%CI = 0.25-0.65, P = 0.001), non-cardiogenic cardiac arrest (OR = 0.35, 95%CI = 0.25-0.48, P = 0.013), previous history of diabetes mellitus (OR = 0.46, 95%CI = 0.27-0.82, P = 0.015) were independent risk factors for ROSC, and cardiac arrest occurred in emergency room (OR = 2.02, 95%CI = 1.02-2.92, P = 0.023), mechanical compression (OR = 1.41, 95%CI = 1.12-1.75, P = 0.043), P_ETCO₂ ≥ 20 mmHg (OR = 2.94, 95%CI = 1.34-4.54, P = 0.012), previous history of acute coronary syndrome (ACS; OR = 2.47, 95%CI = 1.15-3.78, P = 0.043) were protective factors for ROSC. CONCLUSIONS Mechanical compression CPR had no significant differences in the rate of ROSC and 24-hour, 7-day, 28-day survival rates for cardiac arrest patients in the emergency departments compared with hands-only compression CPR. For those who undergone CPR duration more than 60 minutes, mechanical compression was associated with a higher rate of ROSC.

OBJECTIVE: To determine the feasibility of ultrasound to measure blood flow on patients with chest compression cardiopulmonary resuscitation (CPR), and to find out a real-time, noninvasive hemodynamic evaluation method. METHODS: A prospective study was conducted. All adult patients undergoing CPR admitted to Department of Emergency and intensive care unit (ICU) of Zhengzhou People's Hospital from May 2016 to November 2018 were enrolled. The blood flow over the right carotid arteries during chest compressions was recorded with a bedside ultrasound machine. The peak systolic flow velocity (PSV) and end diastolic flow velocity (EDV) of carotid artery were recorded at 1 minute after the start of CPR and 1 minute before the end of CPR. The mean compression frequency during the whole recovery period was recorded, the rate of compression reaching the standard was evaluated by ultrasound (the rate of compression 100-120 times/min was defined as up to standard), and the interruption time of compression was calculated retrospectively according to the ultrasound image data recorded during CPR. RESULTS: Thirty-nine patients were enrolled, and 21 patients were successfully rescued, with a successful rate of 53.8%, the time of restoration of spontaneous circulation (ROSC) was (10.9±5.3) minutes. The time from CPR to retrieve an ultrasound image was 1.1-4.9 minutes, with an average of (2.5±1.2) minutes. Satisfactory ultra-sonographic images were obtained in 28 patients during the whole course of chest compression. The acquisition rate was 71.8% (28/39). In the process of compression, if the frequency of compression was less than 100 times/min or the velocity of carotid artery dropped (PSV < 30 cm/s), the chest compressors should be reminded and corrected in time. The PSV at 1 minute after CPR start of 28 patients with satisfactory ultrasound images was (62.9±18.5) cm/s, and the EDV was (13.9±3.5) cm/s, the PSV at 1 minute before the end of CPR was (55.4±18.4) cm/s, and the EDV was (12.9±3.7) cm/s. There was no significant difference in above parameters between the two time points (both P > 0.05), suggesting that satisfactory resuscitation effect was achieved in the whole process of CPR. The compression frequency of 28 patients was 100-149 times/min with an average of (117±47) times/min. The rate of compression with standard was 85.7% (24/28), and the total interruption time of compression accounted for 4.4% of all compression time (25.9 minutes/587.2 minutes). CONCLUSIONS Ultrasound measurement of common carotid artery blood flow during CPR has the advantage of real-time and non-invasive, and it is feasible in clinical work.

BackgroundRecent advances in extracorporeal membrane oxygenation (ECMO) have led to increasing interest in its use during cardiopulmonary resuscitation (CPR). However, decisions regarding extracorporeal CPR (ECPR) in children are difficult as a result of limited studies, especially in Asia Pacific. The objective of this study was to investigate trends in survival and demographic details for children with ECPR in Asia Pacific recorded in the Extracorporeal Life Support Organization (ELSO) registry from 1999 to 2016 and identify the risk factors associated with in-hospital mortality.

MethodsThe data of children younger than 18 years of age who received ECPR over the past 18 years in Asia Pacific were retrospectively analyzed. The data were extracted from the ELSO registry and divided into two 9-year groups (Group 1: 1999-2007 and Group 2: 2008-2016) to assess temporal changes using univariate analysis. Then, univariate and multiple logistic regression analyses were performed between survivors and nonsurvivors to identify factors independently associated with in-hospital mortality.

ResultsA total of 321 children were included in final analysis, with an overall survival rate of 50.8%. Although survival rates were similar between Group 1 and Group 2 (43.1% vs. 52.5%, χ = 1.67, P = 0.196), the median age (1.7 [0.3, 19.2] months for Group 1 vs. 5.6 [0.8, 64.9] months for Group 2, t = -2.93, P = 0.003) and weight (3.7 [3.0, 11.5] kg for Group 1 vs. 6.0 [3.4, 20.3] kg for Group 2, t = -3.14, P = 0.002) of children increased over time, while the proportion of congenital heart disease (75.9% for Group 1 vs. 57.8% for Group 2, χ = 6.52, P = 0.011) and cardiogenic shock (36.2% for Group 1 vs. 7.2% for Group 2, χ = 36.59, P < 0.001) decreased. Patient conditions before ECMO were worse, while ECMO complications decreased across time periods, especially renal complications. Multiple logistic regression analysis of ECMO complications showed that disseminated intravascular coagulation (DIC), myocardial stunning, and neurological complications were independently associated with increased odds of hospital mortality.

ConclusionsThe broader indications and decreased complication rates make EPCR to be applicated more and more extensive in children in Asia Pacific region. ECMO complications such as myocardial stunning are independently associated with decreased survival.

PURPOSE: The purpose of this study was to develop a first aid coaching program (FACP) and to investigate its effects on the first aid knowledge, confidence, and performance of childcare teachers. METHODS: A Delphi survey that included 16 experts was used to develop the FACP. A total of 60 participants were included to test the effectiveness of the program. The FACP developed using the survey results focused on improving first aid knowledge, confidence, and performance using a coaching-based method. First aid and cardiopulmonary resuscitation (CPR) performance was assessed using 39 items from the program content. RESULTS: Using a 3-round Delphi survey, 6 areas and 42 detailed topics for group and individual coaching programs were developed. The knowledge scores were significantly higher in the experimental group than in the control group (t=4.24, p=.001). The confidence scores were significantly higher in the experimental group than in the control group (F=3.89, p < .001). The performance scores were significantly higher in the experimental group than in the control group (t=12.40, p < .001). CONCLUSION: Continuous application of the FACP among child care teachers is expected to minimize the harm caused by minor accidents at child care facilities. This program should be formally implemented on a consistent basis.

PURPOSE: Recent basic life support (BLS) guidelines recommend a 30:2 compression-to-ventilation ratio (CV2) or chest compression-only cardiopulmonary resuscitation (CC); however, there are inevitable risks of interruption of high-quality cardiopulmonary resuscitation (CPR) in CV2 and hypoxemia in CC. In this study, we compared the short-term outcomes among CC, CV2, and 30:1 CV ratio (CV1). MATERIALS AND METHODS: In total, 42 pigs were randomly assigned to CC, CV1, or CV2 groups. After induction of ventricular fibrillation (VF), we observed pigs for 2 minutes without any intervention. Thereafter, BLS was started according to the assigned method and performed for 8 minutes. Defibrillation was performed after BLS and repeated every 2 minutes, followed by rhythm analysis. Advanced cardiac life support, including continuous chest compression with ventilation every 6 seconds and intravenous injection of 1 mg epinephrine every 4 minutes, was performed until the return of spontaneous circulation (ROSC) or 22 minutes after VF induction. Hemodynamic parameters and arterial blood gas profiles were compared among groups. ROSC, 24-hour survival, and neurologic outcomes were evaluated at 24 hours. RESULTS: The hemodynamic parameters during CPR did not differ among the study groups. Partial pressure of oxygen in arterial blood and arterial oxygen saturation were lowest in the CC group, compared to those in the other groups, during the BLS period (p=0.002 and p < 0.001, respectively). The CV1 groups showed a significantly higher rate of favorable neurologic outcome (swine CPC 1 or 2) than the other groups (p=0.044). CONCLUSION: CPR with CV1 could promote better neurologic outcome than CV2 and CC.
