Umbral crítico de administración en pacientes con trauma severo y reanimación endovascular: ¿Un concepto útil? / Critical Administration Threshold in severe trauma patients and endovascular resuscitation: A useful concept?

Introducción. Se describe la utilidad del umbral crítico de administración (CAT por su denominación en inglés) como herramienta para la reanimación hemostática en pacientes con trauma severo y oclusión endovascular aórtica. Métodos. Revisión retrospectiva de pacientes adultos con hemorragia por trauma, con o sin oclusión endovascular aórtica (REBOA), atendidos entre enero de 2015 y junio de 2020, en un centro de trauma nivel I en Cali, Colombia. Se registraron variables demográficas, severidad del trauma, estado clínico, requerimiento transfusional, tiempo hasta CAT+ y CAT alcanzado (1, 2 ó 3). Resultados. Se incluyeron 93 pacientes, se utilizó REBOA en 36 y manejo tradicional en 57. El grupo REBOA presentó mayor volumen de sangrado (mediana de 3000 ml, RIC: 1950-3625 ml) frente al grupo control (mediana de1500 ml, RIC: 700-2975ml) (p<0,001) y mayor cantidad de glóbulos rojos transfundidos en las primeras 6 horas (mediana de 5, RIC:4-9); p=0,015 y en las primeras 24 horas (mediana de 6, RIC: 4-11); p=0,005. No hubo diferencias estadísticamente significativas en número de pacientes CAT+ entre grupos o tiempo hasta alcanzarlo. Sin embargo, el estado CAT+ durante los primeros 30 minutos de la cirugía fue mayor en grupo REBOA (24/36, 66,7 %) frente al grupo control (17/57, 29,8 %; p=0,001), teniendo este mayor tasa de mortalidad intrahospitalaria frente a los pacientes CAT-. Conclusión. El umbral crítico de administración es una herramienta útil en la reanimación hemostática de pacientes con trauma y REBOA, que podría predecir mortalidad precoz.

Introduction. The objective is to describe the utility of the Critical Administration Threshold (CAT) as a tool in hemostatic resuscitation in patients with severe trauma and REBOA. Methods. Retrospective review between January 2015 and June 2020 of adult patients with hemorrhage secondary to trauma with or without REBOA in a level I trauma center in Cali, Colombia. Demographic variables, trauma severity, clinical status, transfusion needs, time to CAT+ and number of CAT achieved (1, 2 or 3) were recorded. Results. Ninety-three patients were included, in which REBOA was used in 36 and traditional management in 57. The REBOA group had a higher bleeding volume (3000 ml), IQR: 1950-3625 ml vs the control group (1500 ml, IQR: 700-2975 ml) (p<0.001) and a higher rate of PRBC units transfused in the first 6 hours (median 5, IQR: 4-9); p=0.015 and in the first 24 hours (median 6, IQR: 4-11); p=0.005. There were no statistically significant differences in the number of CAT+ patients between groups or time to CAT+. However, CAT+ status during the first 30 minutes of surgery was higher in the REBOA Group (24/36, 66.7%) vs. the control group (17/57, 29.8%; p=0.001), having this group a higher in-hospital mortality rate vs. CAT- patients. Conclusion. CAT is a useful tool in the hemostatic resuscitation of patients with trauma and REBOA that could predict early mortality.

Research progress in complications and their prevention and treatment strategies during extracorporeal membrane oxygenation support for severe trauma / 中华创伤杂志

Extracorporeal membrane oxygenation (ECMO) is a technique in which breathing and circulation are supported extracorporeally. Severe trauma may induce cardiopulmonary failure, for which ECMO can play an adjunctive role in the salvage treatment of circulatory and respiratory failure when conventional treatments are ineffective. Bypass with ECMO can rapidly improve the state such as circulatory failure and hypoxemia in critically ill patients in short term and can partially or fully replace their cardiopulmonary function in long term, winning valuable time for normal recovery of cardiopulmonary function. Because of the physical state of severe trauma patients and the ECMO equipment, there are still various complications clinically. Trauma patients show high risk of bleeding, vulnerability to wound infection and probability of combined organ injury and dysfunction, so more comprehensive measures for the prevention and treatment of complications during the use of ECMO therapy are required. The authors review the research progress in complications and corresponding prevention and treatment strategies during ECMO support for severe trauma, aiming to provide a reference to prevent and treat these complications.

Characteristics and resuscitation effects of out-of-hospital sudden death: a study based on Internet data / 中华危重病急救医学

Objective:To collect the Internet news about "sudden death", analyze its characteristics and resuscitation effects, so as to provide reference for formulating intervention strategies.Methods:The Internet was used to search for "sudden death" and "cardiac arrest" on "Baidu" and "360" websites. Reports of sudden death events were collected from January 2013 to December 2022. The age, gender, characteristics of sudden death, implementation characteristics of cardiopulmonary resuscitation (CPR), and pre-hospital and final clinical outcomes of sudden death patients were recorded and analyzed. Subgroup analyses were performed for pre-hospital and final clinical outcomes. Unconditional multivariate Logistic regression analysis was used to screen the related factors affecting the pre-hospital and final clinical outcomes in patients with sudden death.Results:177 news reports were finally confirmed, involving 177 sudden death patients, including 152 males (85.9%) and 25 females (14.1%), aged (37.27±16.82) years old, and 53.1% in the 16-45 years old group. Triggering factors included strenuous exercise (29.9%), heart disease history (7.9%), overwork (6.2%), staying up late and insomnia (4.0%), activation of emotion (2.8%), and no obvious inducement (48.0%). After on-site first aid, 104 cases (58.8%) achieved restoration of spontaneous circulation (ROSC) before hospital admission, and 18 cases (10.2%) recovered consciousness. After clinical treatment, 109 cases (61.6%) achieved ROSC, 86 cases (48.6%) recovered consciousness, and 22 cases (12.4%) did not report the final outcome. Subgroup analysis showed that compared with patients who achieved pre-hospital ROSC ( n = 104), sudden death in non-ROSC patients ( n = 73) mainly occurred during sleep, in residence and without immediate CPR, full CPR, or automated external defibrillator (AED); and patients who ultimately did not recover consciousness clinically ( n = 91) showed similar characteristics compared with patients who recovered consciousness ( n = 86). Multifactorial Logistic regression analysis showed that immediate CPR [pre-hospital ROSC: odds ratio ( OR) = 8.06, 95% confidence interval (95% CI) was 2.36-27.46; final recovery of consciousness: OR = 9.10, 95% CI was 2.46-33.68] and AED defibrillation (pre-hospital ROSC: OR = 36.31, 95% CI was 4.53-291.19; final recovery of consciousness: OR = 3.53, 95% CI was 1.45-8.61) facilitated pre-hospital achievement of sudden death patients ROSC and final recovery of consciousness. Conclusions:Out-of-hospital sudden death mainly occurs in young people, and vigorous exercise is one of the potential factors for out-of-hospital sudden death, with nearly half having no obvious cause. Immediate and rapid CPR and defibrillation are the simplest and most effective on-site first aid methods. Strengthening public CPR and defibrillation education and training, and advocating healthy lifestyle are effective ways to improve the survival rate of sudden death and reduce the occurrence of sudden death. Based on practical clinical rescue experience, the implementation of bystander CPR by medical personnel is also a factor that cannot be ignored in affecting the clinical outcomes of sudden death patients.

Development and application of an smart emergency respirator with open airway / 中华危重病急救医学

To solve the problems of insufficient airway opening, insufficient or excessive ventilation, ventilation interruption, and the rescuer's physical strength during the process of cardiopulmonary resuscitation (CPR) outside the hospital and in the hospital, and to ensure the accuracy of ventilation frequency rate and tidal volume. Zhongnan Hospital and School of Nursing, Wuhan University, jointly designed and developed a smart emergency respirator with open airway function, that has been granted National Utility Model Patent of China (ZL 2021 2 1557989.8). The device is structured of pillow, pneumatic booster pump and mask. It can be used simply by plugging the pillow under the patient's head and shoulder, turning on the power supply and wearing the mask. The smart emergency respirator can quickly and effectively open the patient's airway and give accurate ventilation with adjustable ventilation parameters. The default settings are 10 times/min in respiratory rate and 500 mL in tidal volume. The whole operation does not require the operator have professional operation ability, which can be independently applied used in any cases without oxygen source or power supply, therefore, the application scenario has no limit. The device has the advantages of small size, simple operation and low production cost, which can reduce human source, save physical strength and significantly improve the quality of CPR. The device is suitable for respiratory support in multiple scenes outside and inside the hospital, and can significantly improve the success rate of treatment.

Chinese consensus of cardiopulmonary resuscitation guides prevention, treatment and rescue of cardiac arrest in pregnancy / 中华危重病急救医学

Pregnant women are a group of people in a special period, once sudden cardiac arrest (CA) occurs, it will threaten the life of both mother and child. It has become a great challenge for hospital, doctors and nurses to minimize maternal mortality during pregnancy. All the efforts should ensure the safety of both mother and child throughout the perinatal period. Because difference of the cardiopulmonary resuscitation strategies for common CA patients of the same age, the resuscitation strategies for CA patients during pregnancy need consider the patient's gestational age and fetal condition. Different resuscitation techniques, such as manual left uterine displacement (MLUD), will involve perimortem cesarean delivery (PMCD). At the same time, drugs should be reasonably used for different causes of CA during pregnancy, such as hypoxemia, hypovolemia, hyperkalemia or hypokalemia and other electrolyte disorders and hypothermia in 4Hs, as well as thrombosis, pericardial tamponade, tension pneumothorax and toxicosis in 4Ts. In view of the fact that many causes of CA in pregnancy are preventable, it is more necessary to introduce guidelines for CA in pregnancy in line with our national conditions for clinical guidance. This paper systematically reviewed the pathophysiological characteristics of CA during pregnancy, the high-risk factors of CA during pregnancy, and identified the correct resuscitation methods and prevention and treatment strategies of CA during pregnancy.

Relationship between arterial blood partial pressure of carbon dioxide and prognosis of neurological function after cardiopulmonary resuscitation / 中国基层医药

Objective:To investigate the relationship between arterial blood partial pressure of carbon dioxide and neurological outcome after cardiopulmonary resuscitation.Methods:The clinical data of 116 patients who underwent cardiopulmonary resuscitation admitted to the Intensive Care Unit and Emergency Department of the Second People's Hospital of Hefei from January 2018 to January 2020 were retrospectively analyzed. According to the average arterial blood partial pressure of carbon dioxide within 24 hours after admission, patients were divided into normal (35 mmHg ≤ PaCO 2 ≤ 55 mmHg, 1 mmHg = 0.133 kPa, n = 44), hypercapnia (PaCO 2 > 55 mmHg, n = 51), and hypocapnia (PaCO 2 < 35 mmHg, n = 21) groups. ICU stay, in-hospital mortality, and neurological outcome at discharge were compared among groups. A logistic regression analysis model was established. The relationship between PaCO 2 and neurological outcome was determined. Results:There were no significant differences in age, sex, cardiac arrest time, acute physiological and chronic health evaluation II score at admission, 1-hour mean arterial pressure, location of cardiac arrest, and initial heart rhythm among the three groups (all P > 0.05). ICU stay in the normal group [(7.23 ± 2.55) days] was significantly higher than that in the hypercapnia [(12.21 ± 4.12) days] and hypocapnia [(11.78 ± 4.72) days] groups ( t = 6.48, 4.59, both P < 0.01). In-hospital mortality in the normal group was 38.6% (17/44), which was significantly lower than 60.8% (31/51) in the hypercapnia group and 66.7% (14/21) in the hypocapnia group ( χ2 = 4.63, 4.47, both P < 0.05). The good neurological outcome rate in the normal group was 55.6% (15/44), which was significantly higher than 25.0% (5/51) in the hypercapnia group and 28.6% (2/21) in the hypocapnia group ( χ2 = 8.38, 5.14, both P < 0.05). Multivariate logistic regression analysis showed that cardiac arrest time, 1-hour mean arterial pressure, acute physiological and chronic health evaluation II score, and PaCO 2 are important factors for neurological outcomes of resuscitated patients at discharge (all P < 0.01). Conclusion:Within 24 hours after cardiopulmonary resuscitation, maintaining a normal PaCO 2 level can help improve the neurological outcome of patients at discharge.

The application of MOOC combined with peer mutual assistance in cardiopulmonary resuscitation teaching / 中华医学教育探索杂志

Objective:To explore the application effect of massive open online course (MOOC) combined with peer mutual assistance in cardiopulmonary resuscitation teaching.Methods:A total of 140 students in the same class of Batch 2015 were divided into the experimental group and the control group. In the teaching of cardiopulmonary resuscitation, the experimental group was based on the MOOC teaching platform, watched videos and topic tests before class, and used the peer mutual assistance in class. While the control group adopted traditional classroom teaching mode. The teaching effect of the two groups were evaluated by comparing the operation assessment scores and questionnaire survey of students' satisfaction with teaching. SPSS 22.0 was used for t-test and Chi-square test. Results:The operating assessment score of the experimental group was (82.20±2.31), and the operating assessment score of the control group was (75.80±1.72). The difference was statistically significant ( t=3.27, P<0.05). The questionnaire survey showed that the course satisfaction and learning motivation of the experimental group were better than those of the control group. In learning burden, the two groups had similar results ( P=0.739). Conclusion:MOOC combined with peer mutual assistance in cardiopulmonary resuscitation teaching can help students better master skills, improve students' course satisfaction and learning motivation, without increasing their learning burden.

Application of a new type of simulated manikin based on the biomechanical characteristics of the simulated thoracic cavity in the teaching and training of cardiopulmonary resuscitation / 中华医学教育探索杂志

Objective:To simulate the biomechanical characteristics of the real human thoracic cavity with a multi-spring group variable damping structure, and to design a new cardiopulmonary resuscitation training manikin based on the simulated thoracic biomechanical characteristics combined with the original electronic feedback system, and to test its application effect in cardiopulmonary resuscitation (CPR) teaching.Methods:A total of 60 undergraduate students majoring in five-year clinical medicine of Batch 2019 in Naval Medical University were selected as the research objects and were randomly divided into the experimental group and the control group, with 30 students in each group. The control group used the traditional manikin for CPR training, and the experimental group used the new type of manikin for CPR training based on the control group. After the training, the two groups of personnel were assessed for single skill. The single skill was mainly manual CPR operations, including artificial respiration and chest compressions. The theory and skill operation assessment of CPR and satisfaction for teaching method in the two groups were compared. SPSS 23.0 was used for statistical analysis.Results:The students in the experimental group scored (54.33±3.09) points in the single skill operation assessment, which were significantly better than that of the students in the control group [(52.33±3.08) points], and the difference was statistically significant ( P<0.05). The follow-up questionnaire showed that the students in the experimental group had a better evaluation of the teaching and training effect of the new type of manikin. Conclusion:Compared with the traditional manikin, the new CPR manikin can simulate the CPR emergency scene of the real human body, which can effectively improve the CPR teaching effect of standardized training for medical students, and help the standardization, normalization, and popularization of CPR technology in China.

Attitudes and experiences of medical staff regarding the presence of family members during the administration of CPR: a Meta synthesis / 中国实用护理杂志

Objective:To systematically integrate the attitudes and experiences of medical staffs towards the family presence during resuscitation and provide a reference for the development of family presence during resuscitation clinical practice in China.Methods:To search PubMed, Embase, Web of Science, The Cochrane Library, CINAHL, CNKI, CBM and Wanfang database for qualitative studies on medical staff's attitudes and experiences of family presence during resuscitation since its inception to August 2022. The quality of the literature was evaluated using the Australian JBI Centre for Evidence-Based Health Care (2017) quality assessment criteria for qualitative studies, which were integrated using a pooled integration approach.Results:A total of 12 papers were included to distil the findings of 74 studies, which were summarized to form 10 new categories and 4 consolidated findings including medical staffs′ attitudes towards and reasons for family presence during resuscitation, the impact of family presence during resuscitation on the resuscitation team, the impact of family presence during resuscitation on patients and families, and the real-life dilemmas and recommendations for medical staffs to allow family presence during resuscitation.Conclusions:We should pay attention to the difficulties and needs of family presence during resuscitation by medical staff, take into account the medical context in China, and improve the humanistic care system in our hospitals by considering hospital management, clinical practice, and the demands of patients and their families, in order to improve the accessibility of family presence during resuscitation by the medical staff.

Role and mechanism of tubastatin A in alleviating brain injury after cardiopulmonary resuscitation by inhibiting endoplasmic reticulum stress-mediated cell apoptosis in swine / 中华急诊医学杂志

Objective:To explore the role and mechanism of tubastatin A (TubA) in alleviating brain injury after cardiac arrest and cardiopulmonary resuscitation (CA-CPR) by inhibiting endoplasmic reticulum stress-mediated cell apoptosis in swine.Methods:Twenty-three conventional male white swine, weighing 33-40 kg, aged 4 to 6 months, were divided into 3 groups by random number table method: sham group ( n=6), CA-CPR group ( n=9), and TubA group ( n=8). The CA-CPR swine model was established by 9 min of electrically induced CA through pacing catheter in the right ventricle and then 6 min of CPR in the CA-CPR group. The CA-CPR swine model was established by the same method, and then a dose of 4.5 mg/kg of TubA at 5 min after resuscitation was intravenously infused in the TubA group. The serum concentrations of neuron specific enolase (NSE) and S100β protein (S100β) were measured using ELISA before modeling and at 1, 2, 4 and 24 h after resuscitation. Neurological deficit score (NDS) was evaluated at 24 h after resuscitation. Thereafter, the animals were euthanized, and brain cortex tissues were harvested, and the expression levels of caspase-12 and caspase-3 were measured using immunohistochemistry. Cell apoptosis index was detected by TUNEL assay. The variables among the three groups were compared with one-way analysis of variance and the Bonferroni hoc test using SPSS software. Results:Twenty-four h after resuscitation, the serum concentrations of NSE and S100β were significantly increased, and NDS was markedly elevated in the CA-CPR and TubA groups compared with the sham group (all P<0.05). Compared with the CA-CPR group, serum concentration of NSE starting 2 h after resuscitation and serum concentration of S100β starting 1 h after resuscitation were significantly decreased in the TubA group [NSE (ng/mL): (23.1±2.0) vs. (20.2±2.0) at 2 h, (28.4±2.3) vs. (23.7±1.9) at 4 h, (32.1±2.7) vs. (26.6±2.0) at 24 h; S100β (pg/mL): (2239±193) vs. (1923±101) at 1 h, (2817±157) vs. (2360±141) at 2 h, (3384±250) vs. (2691±210) at 4 h, (3965±303) vs. (3119±260) at 24 h, all P<0.05], and NDS was markedly reduced (240±30 vs. 63±44, P<0.05). At 24 h after resuscitation, brain cortex tissue detection showed that the expression levels of caspase-12 and caspase-3 were significantly increased, and cell apoptosis index was markedly elevated in the CA-CPR and TubA groups compared with the sham group (all P<0.05). However, the expression levels of caspase-12 and caspase-3 were significantly decreased [caspase-12:(7.1±0.7) vs. (4.2±0.4); caspase-3: (13.3±1.6) vs. (7.7±0.8), all P<0.05], and cell apoptosis index was markedly reduced in the TubA group compared to the CA-CPR group [(31.1±8.6) vs. (17.3±2.2), P<0.05]. Conclusions:TubA alleviates brain injury and neurological dysfunction after CA-CPR in swine, which may be related to the inhibition of cell apoptosis mediated by endoplasmic reticulum stress.

Application and analysis of competition based training mode for first aid skills in residency program / 中华急诊医学杂志

Objective:To explore the model of first aid skills training based on competition.Method:The second-year residents who participated in the competition in 2021 ( n = 142) were selected. According to whether they attended BLS training in the first year, they were divided into group A ( n = 88) who attended BLS training and group B ( n = 54) who did not. Chi-square test, T test, Wilcoxon rank sum test and Logistic regression were used in our study. Results:There was no significant difference in gender and specialty between both groups (female, 62.5% vs. 68.5%, P= 0.466; TCM, 50% vs. 53.7%, P= 0.668), but the real resuscitation experience of group A was more than that of group B (40.9% vs. 9.3%, P= 0.000). The qualified rate of CPR and the compression score in group A was higher than that in group B [(81.8% vs. 61.1%, P = 0.006; (30±5) vs. (25 ±10), P= 0.001], including compression frequency, depth, rebound and compression/respiration rate (73.9% vs. 55.6%, P= 0.024; 88.6% vs. 70.4%, P= 0.006; 96.6% vs. 87%, P= 0.031). In the theoretical examination, the correct rates of electrocardiogram [(53.63±2.9)% vs. (50.44±2.57)%] and first aid medication [(57.38±3.55)%, P = 0.001] in the two groups were significantly lower than the qualified rate. After adjusting other factors, Logistic regression analysis showed that the CPR qualification rate in group A was 2.769 times higher than that in group B ( P= 0.015, 95% CI 1.215~6.311) Conclusions:The first aid skills training mode based on competition can objectively reflect first aid skills level of residents. We found that the quality of CPR skills was not related to gender, specialty and real CPR experiences but experience of BLS training was an independent influencing factor. And how to identify and manage arrhythmias and how to choose different emergency drugs are urgent emergency skills for residents to improve.
