In the context of continuously deepening medical and health system reforms and comprehensively promoting the "Healthy China" strategy, Henan Provincial People's Hospital has established a regional collaborative and vertically integrated critical care service structure and network. This initiative aims to enhance information empowerment, strengthen regional collaboration, improve the insufficient primary medical services, and ensure timely and effective treatment for critically ill patients. By establishing a comprehensive dispatch service platform for regional collaborative critical care, building a "top-down" remote medical collaboration network, and forming a cross-regional specialty alliance for critical care, the hospital has improved the efficiency of medical services and enhanced regional capabilities for treating critically ill patients. Simultaneously, for critically serious patients and those with complex diseases at primary medical institutions, a one-stop consultation and referral service has been implemented. This service adopts a "three specialists" approach and a multidisciplinary consultation mechanism within the hospital, constructs a multi-dimensional critical care transfer mode integrating air, ground, and the internet, creates a regional collaborative rescue mode, and implements full-cycle treatment for critically serious patients. The comprehensive, flexible, and efficient service pathway for regional collaborative critical care established by this system ensures timely and safe treatment for critically ill patients, promotes the distribution of high-quality medical resources, and effectively addresses issues such as uneven distribution of high-quality medical resources and varying levels of critical care capabilities. It has facilitated the formation of a new tiered diagnosis and treatment order characterized by "first diagnosis at the primary level, two-way referral, separate treatment for acute and chronic diseases, and vertical integration". This approach has enhanced the diagnostic and comprehensive service capabilities of primary medical institutions. Currently, by strengthening information empowerment and sharing, creating a full-process critical care diagnosis and treatment model, providing medical assistance and cultivating primary-level critical care talent, and promoting appropriate technologies, the hospital has gradually overcome challenges such as barriers to information exchange and sharing between hospitals, overloaded critical care teams, high pressure on patient reception and transfer, and limited critical care capabilities at primary medical institutions. This article summarizes the construction and practical application of this regionally coordinated critical care system, aiming to provide a reference for the management of critical care treatment.

OBJECTIVE: To explore the effects of veno-venous extra corporeal carbon dioxide removal (V-V ECCO₂R) on local mechanical power and gas distribution in the lungs of patients with mild to moderate acute respiratory distress syndrome (ARDS) receiving non-invasive ventilation. METHODS: Retrospective research methods were conducted. Sixty patients with mild to moderate ARDS complicated with renal insufficiency who were transferred to the respiratory intensive care unit (RICU) through the 96195 platform critical care transport green channel from January 2018 to January 2020 at the collaborative hospitals of Henan Provincial People's Hospital were enrolled. According to different treatment methods, they were divided into a conventional treatment group and an ECCO₂R group, with 30 patients in each group. Both groups received standard treatments including primary disease treatment, airway management, and non-invasive ventilation. The conventional treatment group received bedside continuous renal replacement therapy (CRRT), and the ECCO₂R group received V-V ECCO₂R treatment. General information of patient such as gender, age, cause of disease, and acute physiology and chronic health evaluation II (APACHE II) were recorded; arterial blood gas analysis was performed before treatment and at 12 hours and 24 hours during treatment, recording arterial partial pressure of oxygen (PaO₂), arterial partial pressure of carbon dioxide (PaCO₂), and oxygenation index (PaO₂/FiO₂). Respiratory mechanics parameters [tidal volume, respiratory rate, maximal inspiratory pressure (MIP), and maximal expiratory pressure (MEP)] were recorded, and the rapid shallow breathing index (RSBI) was calculated; electrical impedance tomography (EIT) was used to measure regional of interest (ROI) values in different lung areas at 12 hours and 24 hours of treatment, and the pulmonary mechanical energy was calculated. RESULTS: The arterial blood gas analysis indicators, respiratory mechanics parameters, and pulmonary mechanical energy of patients in the conventional treatment group and ECCO₂R group improved significantly after 24 hours of treatment compared to 12 hours of treatment (all P < 0.05). The levels of PaCO₂, RSBI, total mechanical power, and non-dependent zone mechanical power in the ECCO₂R group were significantly lower than those in the conventional treatment group at both 12 hours and 24 hours during the treatment [PaCO₂ (mmHg, 1 mmHg ≈ 0.133 kPa): 44.03±2.96 vs. 49.96±2.50 at 12 hours, 41.65±3.21 vs. 48.53±2.33 at 24 hours; RSBI (times×min^-1×L^-1): 88.67±4.05 vs. 92.35±4.03 at 12 hours, 77.66±4.64 vs. 90.98±4.21 at 24 hours; total mechanical power (mJ): 10.40±1.15 vs. 12.93±1.68 at 12 hours, 11.13±1.18 vs. 14.05±1.69 at 24 hours; non-dependent zone mechanical power (mJ): 7.15±0.84 vs. 7.98±0.75 at 12 hours, 7.77±0.93 vs. 9.13±1.10 at 24 hours], and MEP and MIP in the ECCO₂R group were significantly higher than those in the conventional treatment group at both 12 hours and 24 hours during the treatment [MEP (cmH₂O, 1 cmH₂O ≈ 0.098 kPa): 89.88±5.04 vs. 86.09±5.57 at 12 hours, 96.57±2.59 vs. 88.66±2.98 at 24 hours; MIP (cmH₂O): 47.64±2.82 vs. 41.93±2.44 at 12 hours, 60.11±6.53 vs. 43.63±2.80 at 24 hours], the differences were statistically significant (all P < 0.05). CONCLUSIONS V-V ECCO₂R combined with non-invasive ventilation can effectively reduce the regional tidal volume, mechanical power, and respiratory rate in the non-gravitational dependent zones of patients with mild to moderate ARDS, and improve respiratory distress and oxygenation status.

Stroke rescue features strong time sensitivity and high complexity. Minimizing the time of consumption in pre-hospital and in-hospital stroke rescue is key to improve stroke rescue efficiency and reduce the disability rate. In December 2017, a tertiary hospital launched the construction of a one-stop stroke rescue platform. This platform was centered on " multi-mode image fusion operating room" , operating as a one-stop rescue mode integrating emergency admission, imaging examination, intravenous thrombolytic therapy, mechanical thrombolytic therapy, postoperative evaluation, and so on. The seamless convergence workflow of pre-hospital, in-hospital and post-hospital could effectively optimize the physical rescue pathway. In order to ensure the efficient and orderly operation of the platform, the hospital adopted such measures as multidisciplinary integration, pre-hospital and in-hospital integration construction, and regional stroke care network. Since its operation in September 2019, the platform has treated more than 1 000 patients by December 2021. The application of the platform had effectively improved the efficiency of stroke rescue, led the development of regional stroke rescue system, and provided the reference for raising the stroke rescue capacity and management level in China.

Objective:To assess the application of extracorporeal membrane oxygenation (ECMO) regional treatment pattern in patients with severe cardiopulmonary diseases.Methods:A retrospective analysis was conducted. Patients with severe cardiopulmonary disease who were transferred to Henan Provincial People's Hospital after ECMO treatment in cooperative hospitals were selected. The patients who received regular ECMO treatment from June 2017 to May 2018 were enrolled as the control group, and the patients who received ECMO regional treatment from June 2018 to May 2019 were selected as the observation group. The ECMO regional treatment pattern referred to implement a referral program for critical patients in primary hospitals, which mainly included the establishment of ECMO regional cooperative treatment network and ECMO referral team, the formulation of ECMO referral management standards, and the promotion of the merging of high-quality medical resources. Time of establishment of ECMO, ECMO regional treatment satisfaction, and the incidence of adverse events were also compared.Results:There were 27 patients enrolled in the control group and 64 patients in the observation group. There were no significant differences in gender, age, body mass index (BMI), ECMO mode, hypertension or coronary heart disease history between the two groups. Compared with the control group, the time for establishment of ECMO in the observation group was significantly shorter (minutes: 38.10±17.19 vs. 54.67±41.30, t = 2.715, P = 0.008), the ECMO treatment satisfaction of the observation group was also significantly higher than that of the control group (98.4% vs. 88.9%, χ 2 = 4.120, P = 0.042), and the incidence of ECMO referral adverse events was significantly lower than that of the control group (6.25% vs. 25.93%, χ 2 = 6.918, P = 0.009). Conclusion:The ECMO regional collaborative pattern in patients with severe cardiopulmonary diseases can shorten the time for establishment of ECMO, improve the satisfaction of ECMO treatment, and reduce the incidence of adverse events in ECMO referral.

Objective    To investigate the safety and effectiveness of minimally invasive coronary artery bypass grafting (MICABG) through comparing the perioperative clinical effects of conventional surgery and MICABG. Methods    A total of 543 patients in the single medical group of Beijing Anzhen Hospital who underwent beating coronary artery bypass grafting from January 2017 to September 2020 were collected, including 161 patients receiving MICABG (a minimally invasive group, 143 males and 18 females, aged 60.08±9.21 years), 382 patients receiving median thoracotomy (a conventional group, 284 males and 98 females, aged 61.68±8.81 years). The propensity score was used to match 143 patients in each of the two groups, and the perioperative data of the two groups were summarized and analyzed. Results    There was no death, perioperative myocardial infarction or stroke in the minimally invasive group. Compared with the conventional group, the minimally invasive group had longer operation time (296.36±89.4 min vs. 217.80±50.63 min, P=0.000), less number of bypass grafts (2.86±1.03 vs. 3.17±0.78, P=0.005), shorter postoperative hospital stay (6.29±1.46 d vs. 6.78±2.61 d, P=0.031), less drainage on postoperative day 1 (339.57±180.63 mL vs. 441.92±262.63 mL, P=0.001) and lower usage rate of inotropic drugs (9.09% vs. 26.57%, P=0.001). There was no statistical difference between the two groups in postoperative ICU stay ventilator assistance time, blood transfusion rate, secondary thoracotomy rate, or use of mechanical equipment. Conclusion    Reasonable clinical strategies can ensure the satisfactory overall safety of MICABG. In addition, it has the advantages of shorter postoperative hospital stay, less bleeding and smaller dosage of inotropic drugs.

Objective    To study the learning curve of minimal invasive coronary artery bypass grafting (MICS CABG) and the influence on the perioperative clinical effects by analyzing operation time. Methods    From March 2012 to November 2020, 212 patients underwent MICS CABG by the same surgeon. Among them, 59 patients (52 males and average age of 62.89±8.27 years) with single vessel bypass grafting were as a single-vessel group and 153 patients (138 males, average age of 59.80±9.22 years) with multi-vessel bypass grafting were as a multi-vessel group. Two sets of operation time-operation sequence scatter plots were made and learning curve was analyzed by cumulative summation (CUSUM) and regression method of operation time. The surgical data of each group before and after the inflection point of the learning curve were compared with the main clinical outcome events within 30 days after surgery. Results    There was no death, perioperative myocardial infarction and stroke in 212 MICS CABG patients and no transfer to cardiopulmonary bypass or redo thoracotomy. The learning curve conformed to the cubic fitting formula. In the single- vessel group, CUSUM (x operation number)=–1.93+93.45×x–2.33×x2+0.01×x3, P=0.000, R2=0.986, the tipping point was 27 patients. In the multi-vessel group, CUSUM (x)=y=2.87+1.15×x–1.29× x2+3.463×x3, P=0.000, R2=0.993, and the tipping point was 59 patients. The two sets of case data were compared before and after the learning curve and there was no statistical difference in main clinical outcomes within 30 days (mortality, acute myocardial infarction, stroke, perioperative blood transfusion rate), ventilator tube, and intensive care unit retention. Conclusion    The learning curve of MICS CABG conforms to the cubic formula, and the process transitions from single to multiple vessels bypass. To enter the mature stage of the learning phase, a certain number of patients need to be done. Reasonable surgical procedures and quality control measures can ensure the safety during the learning phase.

Background: Most patients including health care workers (HCWs) survived the coronavirus disease 2019 (COVID-19), however, knowledge about the sequelae of COVID-19 after discharge remains limited. Methods: A prospectively observational 3-month follow-up study evaluated symptoms, dynamic changes of severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) IgG and IgM, lung function, and high resolution computed tomography (HRCT) of survivors of COVID-19 after discharge at Wuhan Union Hospital, China. Results: Seventy-six survivors (55 females) with a mean age of 41.3 ± 13.8 years were enrolled, and 65 (86%) were HCWs. A total of 69 (91%) patients had returned to their original work at 3-months after discharge. Most of the survivors had symptoms including fever, sputum production, fatigue, diarrhea, dyspnea, cough, chest tightness on exertion and palpitations in the three months after discharge. The serum troponin-I levels during the acute illness showed high correlation with the symptom of fatigue after hospital discharge (r = 0.782; P = 0.008) and lymphopenia was correlated with the symptoms of chest tightness and palpitations on exertion of patients after hospital discharge (r = −0.285, P = 0.027; r = −0.363, P = 0.004, respectively). The mean values of forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), FEV1/FVC, total lung capacity and diffusion capacity were all normal (> 80% predicted) and lung HRCTs returned to normal in most of the patients (82%), however, 42% of survivors had mild pulmonary function abnormalities at 3-months after discharge. SARS-CoV-2 IgG turned negative in 11% (6 of 57 patients), 8% (4 of 52 patients) and 13% (7 of 55 patients), and SARS-CoV-2 IgM turned negative in 72% (41 of 57 patients), 85% (44 of 52 patients) and 87% (48 of 55 patients) at 1-month, 2-months and 3-months after discharge, respectively. Conclusion Infection by SARS-CoV-2 caused some mild impairments of survivors within the first three months of their discharge and the duration of SARS-CoV-2 antibody was limited, which indicates the necessity of long-term follow-up of survivors of COVID-19.

With the development of society and economy, the disease spectrum of Chinese residents has undergone a major change, and the public health emergencies have occasionally occurred. The new situation has put forward higher requirements on the emergency capacity, professional technical level and treatment quality of critical care treatment system. Combining with the advantages of hospital aviation, ground and Internet emergency, Henan Provincial People's Hospital established a new construction path of emergency and critical care treatment system, namely "trinity" rescue system of aviation, ground and Internet emergency treatment and the "five-ring" model of critical care treatment system in hospital. The purpose of this paper is to summarize the practical experience of the construction of emergency and critical care system in Henan Provincial People's Hospital, so as to provide reference for the management of emergency and critical care in China.
