Latest 7vs 6th edition of the new coronary pneumonia treatment plan comparisonSIFIC Infection Team SIFIC Infection Evidence-Based Information 4 days agoThe new part below is marked with bold red, please note Time is short, if there is a omission please understandKey points of the seventh update:1. Increase the reminder for importing new cases 2. Increased child and pregnancy concerns 3. Increased support for patients with severe illness 4. Increased pathological changes 5. Increase in early warning indicators for critical and critical illness 6. Serological diagnostic methods incorporatedComparison of the sixth and seventh editions of the new coronary pneumonia treatment planWei Yanni, Zhou Miaoqing, Shi Qingfeng, Zhou, Han Ling-like ProofreadingSince December 2019, a new type of coronavirus pneumonia outbreak has occurred in Wuhan, Hubei Province, and with the spread of the epidemic, such cases have been detected in other parts of China and in many countries abroad. As an acute respiratory infectious disease, the disease has been included in the "Chinese People's Republic of Infectious Diseases Prevention and Control Act" provisions of the Class B infectious diseases, according to the management of Class A infectious diseases. Through a series of preventive control and medical treatment measures, the rising momentum of the epidemic in China has been curbed to a certain extent, the epidemic in most provinces has eased, but the number of cases abroad is on the rise. With the in-depth clinical manifestations of the disease, pathological understanding and the accumulation of medical experience, in order to further strengthen the early diagnosis and treatment of the disease, improve the cure rate, reduce the mortality rate, the greatest possible avoidance of hospital infection, while reminding attention to the spread and spread of imported cases abroad, we revised the "new coronavirus pneumonia diagnosis and treatment program (trial sixth edition) " to form a new coronary disease pneumonia treatment program (trial seventh edition).01 PART Pathogen characteristicsThe new coronavirus belongs to the beta genus coronavirus, has a film, particles are round or oval, often polymorphic, diameter 60-140 nm. Its genetic characteristics are significantly different from SARS-CoV and MERS-CoV (SARSr-CoV and MERSr-CoV in version 6). Current studies have shown that the bat-SL-CoVZC45 is more than 85% homogenous. In vitro isolation culture, the new coronavirus can be found in the human respiratory epithelial cells for about 96 hours, while in the Vero E6 and Huh-7 cell lines isolated culture takes about 6 days.Much of the understanding of coronary virus physical and chemical properties comes from the study of SARS-CoV and MERS-CoV. Viruses are sensitive to UV rays and heat, 56 degrees C for 30 minutes, ether, 75% ethanol, chlorine disinfectants, peroxyacetic acid and chloroform and other lipid solvents can effectively inactivate the virus, chlorine can not effectively inactivate the virus.02 PART Epidemiological characteristics(i) The source of infection. At present, the main sources of infection seen are patients with new coronavirus infection. Asymptomatic infected people can also be a source of infection.(ii) Means of communication. Transmission through respiratory droplets and close contact is the main route of transmission. There is a possibility of aerosol propagation in a relatively closed environment exposed to high concentrations of aerosols for long periods of time. Increase: Because new coronaviruses can be isolated in feces and urine, it should be noted that feces and urine cause aerosols or contact transmission to environmental pollution.(iii) Vulnerable groups. Crowds are generally susceptible.03 PART Pathological changesThis chapter is all new, please noteAccording to the limited autopsy and puncture hispathological observations, the results are summarized below.(i) The lungs.The lungs showed varying degrees of real change.The alveolar cavity is characterized by slurry, fibrin oozing and transparent membrane formation; Type II alveoli epithelial cells significantly increased, and some cells fell off. Type II alveoli epithelial cells and macrophages are visible in the inclusion. The alveoli is filled with blood vessels and edema, and it can be seen that mononucleosis and lymphocytes are immersed and transparent thrombosis in the blood vessels. Pulmonary tissue lesions bleed, necrosis, and hemorrhagic infarction can occur. Partial alveolar cavity oozing metabolites and pulmonary fibrosis.The epithelial part of the branch branch mucosa part of the lung falls off, and mucus and mucus hydrants are visible in the cavity. A small number of alveoli is overinflated, alveoli breaks or cysts are formed.Coronary virus particles are visible in the broncochle mucous epithelial and type II alveoli epithelial cytoplasm under the electroscope. Immunohislification staining showed that partial alveoli epithelial and macrophages were positive for the new coronavirus antigen, and RT-PCR tested positive for the new coronavirus nucleic acid.(ii) Spleen, pulmonary lymph nodes and bone marrow.The spleen is significantly reduced. The number of lymphocytes was significantly reduced, lesions of hemorrhage and necrosis, macrophages in the spleen were proliferation and visible phage; Immunized staining showed a decrease in both CD4-T and CD8-T cells in the spleen and lymph nodes. The number of three-line cells in the bone marrow decreased.(iii) Heart and blood vessels.Myocardial cells are visible to denaturation, necrosis, and a small number of mononucleocytes, lymphocytes, and/or neutrophils are immersed in the interstitial. Part of the endothelial fall, inflammation of the lining and thrombosis.(iv) Liver and gallbladder.The volume increases and the dark red. Hepatocellular denaturation, lesions necrosis accompanied by neutrophil leaching; hepatic blood sinuses are congested, conciliator areas see lymphocytes and monocytocell leaching, microthofcardia formation. The gallbladder is highly charged.(v) Kidneys.The glomerular balloon cavity sees protein oozing, the epithelial degeneration of the kidney tube, shedding, visible transparent tube type. Interstitial congestion, microthrombostosis and lesions fibrosis can be seen.(vi) Other organs.Brain tissue is congestive, edema, and part of the neurons are denatured. Adrenal glands see lesionne. The epithelial epithelial of the esophagus, stomach and intestinal tract is denatured, necrosis, and shedding to varying degrees.04 PART Clinical characteristics(i) Clinical performance.Based on the current epidemiological investigation, the incubation period is 1 to 14 days, mostly 3 to 7 days.To fever, dry cough, fatigue as the main performance. A small number of patients have symptoms such as nasal congestion, runny nose, sore throat, myalgia and diarrhea. Most of the seriously ill patients appear breathing difficulties and/ or hypoxemia after one week of the onset of the disease, the severe case can quickly progress to acute respiratory distress syndrome, sepsis shock, difficult to correct metabolic acidosis and blood clotting dysfunction and multi-organ failure. It is worth noting that the course of heavy, critical patients can be low-to-medium fever, or even no obvious fever.New: Some children and newborn cases of symptoms may be atypical, as vomiting, diarrhea and other digestive symptoms or only manifested as mental weakness, shortness of breath.Light patients showed only low fever, mild fatigue, and no pneumonia.From the current case situation, most patients have a good prognosis, a few patients are in critical condition. Older people and people with chronic underlying diseases have a poorer prognosis. New: The clinical process of maternal pneumonia with the new coronavirus is similar to that of patients of the same age. The symptoms in children are relatively mild.(ii) Laboratory examination.1. General check (new subheading)The total number of peripheral white blood cells in the early stages of the disease is normal or decreased, it can be seen (new) lymphocyte count decreased, some patients can appear hepatic enzymes, lactic acid dehydrogenase (LDH), myosise and myoglobin increase; Most patients have C-reactive protein (CRP) and elevated blood, and calcite is normal. Severed D-dipolymer selevated, peripheral blood lymphocytes reduced sexuality. Heavy, critically ill patients often have elevated inflammatory factors.2. Pathogen and serological examination (new subheading)(1) Pathogen examination: New coronavirus nucleic acid can be detected in samples of nasopharyngeal swabs, sputum and other lower respiratory secretions, blood, feces, etc. using RT-PCR or/and NGS (new examination methods). It is more accurate to detect lower respiratory tract specimens (sputum or airway extracts). The specimen is collected and sent for examination as soon as possible. (Revised text)New: (2) Serological examination: The new coronavirus-specific IgM antibody is more positive after 3-5 days of onset, And the Recovery period of IgG antibody is 4 times and above higher than that of the acute period.(iii) Chest imaging.Early appearance of multiple small patch shadow and interstitial changes, with lung band obvious. Then developed into double lung multiple grinding glass shadow, soaked shadow, serious can appear lung real change, chest cavity fluid is rare.05 PART Diagnostic standards(i) Suspected cases.Combined with the following epidemiological history and clinical manifestations:Epidemiological history(1) The travel or residence history of Wuhan City and surrounding areas, or other reported communities, within 14 days of the onset of the disease; (2) A history of exposure with a new coronavirus infection (nucleic acid detection) within 14 days prior to the onset of the disease; (3) Have been exposed to patients from Wuhan city and surrounding areas within 14 days of the onset of the disease, or from patients with fever or respiratory symptoms in the community with case reports; (4) New incidence of clustering: (2 cases of fever and above and/or respiratory symptoms occurred within 2 weeks in small areas such as homes, offices, school classes, etc.).2. Clinical performance(1) Fever and/or respiratory symptoms; (2) with the imaging characteristics of the above-mentioned new coronavirus pneumonia; (3) The total number of white blood cells in the early stages of the disease is normal or decreased, and the lymphocytes count is normal or decreased.There is any one in the history of epidemiology and conforms to any 2 in clinical performance. If there is no clear epidemiological history, it is consistent with the 3 articles in clinical performance.(ii) Confirmed cases. (Added simultaneous and or serological)Suspected cases have one of the following pathogen or serological evidence:1. Real-time fluorescent RT-PCR testpositive for new coronavirus nucleic acid; 2. Viral gene sequencing, highly homologous with known new coronaviruses; 3. New: Serum new coronavirus-specific IgM antibodies and IgG antibodies positive;06 PART Clinical type(i) Light.Clinical symptoms were mild, and no manifestations of pneumonia were seen in imaging.(ii) Normal type.With fever, respiratory tract and other symptoms, imaging can be seen pneumonia performance.(iii) Heavy duty.Adults are eligible for any of the following: 1.

Patients who have close contact with new coronavirus infection, even if the common respiratory pathogentest sat positive, it is recommended to promptly enter the new coronavirus pathogen test.New: The suspected cases were tested negative for two consecutive new coronavirus nucleic acids (at least 24 hours apart) and 7 days after the onset of the new coronavirus-specific antibodies IgM and IgG were still negative and the suspected cases could be ruled out.10 PART Treatment(i) Determining the place of treatment on the basis of the condition.1. Suspected and confirmed cases shall be treated in isolated hospitals with effective isolation and protective conditions, suspected cases shall be treated in single-room isolation, and confirmed cases may be treated in the same room by multiple persons. 2. Critical cases should be treated with ICU as early as possible.(ii) General treatment.1. Bed rest, strengthen support for treatment, ensure adequate heat, pay attention to water, electrolyte balance, maintain internal environmental stability, closely monitor vital signs, refertos to oxygen saturation, etc.2.

Timely and effective oxygen therapy measures, including nasal catheterization, mask oxygen feed and high-flow oxygen therapy through the nose. New: Conditional treatment of hydrogen-oxygen mixture inhalation gas (H2/O2: 66.6%/33.3%).4. Antiviral therapy: a-interferon can be tried (adults 5 million U or meta-dose, addster injection water 2nd, 2 times daily atomized inhalation), lopinavir/litonavir (adult 200mg/50mg/capsule, 2 capsules per time, 2 times daily, Treatment not more than 10 days), ribavirin (recommended in combination with interferon or lopinavir/litonnavir, adults 500 mg/time, 2 to 3 intravenous injections per day, treatment not more than 10 days), modified use method: chloroquine phosphate (18-65 years of adults. Those who weigh more than 50 kg, 500 mg each time, 2 times a day, 7 days of treatment, weight less than 50 kg, the first and second day each 500 mg. 2 times a day, the third to seventh day each 500 mg. 1 time per day), Abidor (adult 200 mg, 3 times a day, no more than 10 days of treatment).Modification: Be aware of adverse reactions to the above drugs, contraindications (e.g. the prohibition of chloroquine in people with heart disease), and interactions with other drugs.Further evaluation of the efficacy of the drug currently being tested in clinical applications. It is not recommended to apply 3 or more antiviral drugs at the same time, and stop using the relevant drugs in the event of intolerable side effects.New: The treatment of pregnant patients should consider the number of weeks of pregnancy, as far as possible to choose drugs that have a low impact on the fetus, and whether to terminate the pregnancy after treatment and other issues, and inform informed.5. Antibacterial drug treatment: Avoid the blind or inappropriate use of antimicrobial drugs, especially the combined use of broad-spectrum antimicrobial drugs.(iii) Treatment of heavy and critical cases.1. Principles of treatment: On the basis of treatment of the disease, actively prevent and control complications, treat underlying diseases, prevent secondary infections, and provide timely organ functional support.2. Breathing support:(1) Oxygen therapy: Heavy patients should receive nasal catheters or masks to absorb oxygen and promptly assess respiratory distress and/or hypoxemia for relief.(2) High-flow nasal catheter oxygen therapy or noninvasive mechanical ventilation: When the patient is undergoing standard oxygen therapy breathing distress and/or hypoxemia is unable to relieve, consider using high-flow nasal catheter oxygen therapy or noninvasive ventilation. If the condition does not improve or even worsen within a short period of time (1-2 hours), the trachea intubation and invasive mechanical ventilation should be carried out in a timely manner. (3) Invasive mechanical ventilation: the use of pulmonary protective ventilation strategy, i.e. low tide air volume (6-8mL/kg ideal weight) and low-level airway platform pressure (platform pressure 30cmH2O) for mechanical ventilation to reduce ventilator-related lung damage.New: In ensuring that the airway platform pressure W 35cmH2O, can be appropriate lying high PEEP, to maintain the airduction wet, avoid long-term sedation, early wake up patients and lung rehabilitation treatment.More patients exist in the human machine out of sync, should be timely use of sedatives and muscle loose agent.New: According to the airway secretion situation, choose closed sputum, if necessary, bronchoscopy examination to obtain the appropriate treatment.(4) Rescue treatment: For patients with severe ARDS, pulmonary resuscitation is recommended. Where adequate human resources are available, more than 12 hours of lying-down ventilation should be performed daily. Those with poor mechanical ventilation in the lying position should consider the in vitro membrane pulmonary oxygenation (ECMO) as soon as possible if conditions permit.New: Its related indications: (1) at 90% of FiO, oxygenation index is less than 80mmHg, lasting more than 3-4 hours; For patients with pure respiratory failure, the VV-ECMO model is preferred, and the VA-ECMO model is preferred if circulatory support is required. When the underlying disease is under control and cardiopulmonary function shows signs of recovery, the withdrawal test can begin.3. Circulation support: improve microcirculation on the basis of adequate liquid resuscitation, use of vascularly active drugs, added: close monitoring of changes in blood pressure, heart rate and urine volume in patients, as well as lactic acid and alkali surplus in arterial blood gas analysis, noninvasive or invasive hemodynamic monitoring, such as ultrasound doppler method, echocardiogram, invasive blood pressure or persistent cardiolycation (PiCCO) monitoring. In the course of treatment, pay attention to the liquid balance strategy, to avoid excessive and inadequate.New: If it is found that the sudden increase in the patient's heart rate is greater than the base value of 20% or blood pressure drop of about 20% of the base value, if accompanied by poor skin perfusion and decreased urine, etc. , patients should be closely observed whether there is sepsis shock, gastrointestinal bleeding or heart failure.New: 4. Renal failure and renal replacement therapy: Kidney impairment in critically ill patients should actively look for causes of renal impairment, such as low perfusion and medication. Treatment of patients with renal failure should pay attention to body fluid balance, acid-base balance and electrolyte balance, and should pay attention to nitrogen balance, heat and trace elements in nutritional support treatment. Patients with severe illness can choose continuous renal replacement therapy (continuous renal therapy, CRRT). Its signs include: (1) hyperkalemia; (2) acidosis; (3) pulmonary edema or overburdened water; and (4) liquid management when multi-organ insufficiency is inexhaustive.5. Rehabilitation plasma treatment: suitable for patients with rapid progress, heavy and critical conditions. The usage reference is the Clinical Treatment Plan for Plasma In the Recovery period of The New Coronary Pneumonia Recovery (Trial 2nd Edition).Added: 6. Blood purification treatment: blood purification system includes plasma replacement, adsorption, irrigation, blood/plasma filtration, etc., can remove inflammatory factors, block "cytokine storm", thus reducing the damage of the inflammatory reaction to the body, can be used for heavy, critical patients in the early and medium period of treatment of cytokinetic factor storm.7. Immunotherapy: For patients with widespread lesions of double lung and heavy patients, and laboratory tests for elevated LEVELs of IL-6, tocoamono-resistance therapy can be tried. The first dose is 4-8 mg/kg, the recommended dose is 400 mg, 0. 9% physiological saline diluted to 100 ml, the injection time is greater than 1 hour, the first drug treatment is not good, can be applied once after 12 hours (the dose is the same, the cumulative number of doses up to 2 times, the maximum amount of a single dose does not exceed 800 mg. Be aware of allergic reactions, which are disabled by people with TB and other activities.8. Other treatment measures: For oxygenation index sexual deterioration, rapid progress in imaging, body inflammation should be overactivated in patients, as appropriate in the short term (3 to 5 days) the use of glucocorticoids, the recommended dose does not exceed the equivalent of metastasis nylon 1 to 2 mg / kg / day, should pay attention to the larger dose of glucocorticoiddue due to immunosuppressive effect, will delay the removal of coronavirus; (Delete section and new duplicates above)New: Heavy, critical cases in children may, as appropriate, consider giving intravenous drips of C globulin.Pregnant women with severe or critical new coronavirus pneumonia should actively terminate their pregnancy, with caesarean section being the first choice.Patients often have anxiety and fear, should strengthen psychological guidance.(4) Chinese medicine treatment.This disease belongs to the category of Chinese medicine "epidemic" disease, because the disease feels the "epidemic" gas, all places can be based on the disease, local climate characteristics and different physical conditions, reference to the following programs for dialectical treatment.

Body temperature returns to normal for more than 3 days; 2. There has been a marked improvement in respiratory symptoms; 3. Pulmonary imaging showed a significant improvement in acute oozing lesions; 4. Two consecutive respiratory samples such as sputum and nasopharyngeal swabs tested negative for nucleic acid (at least 24 hours apart).Those who meet the above conditions may be discharged from the hospital.(2) Precautions after discharge from hospital.1. The designated hospital should make good contact with the primary medical institutionwhere where the patient lives, share the medical records, and promptly push the patient's information to the patient's jurisdiction or place of residence, the neighborhood committee and the primary health care institution.2.

增加重症、危重症预警指标6. 血清学诊断方法纳入新冠肺炎诊疗方案第六、七版对比韦艳妮、周谋清、史庆丰、周密、韩玲样校对2019年12月以来,湖北省武汉市出现了新型冠状病毒肺炎 疫情,随着疫情的蔓延,我国其他地区及境外多个国家也相继 发现了此类病例。该病作为急性呼吸道传染病已纳入《中华人 民共和国传染病防治法》规定的乙类传染病,按甲类传染病管理。通过釆取一系列预防控制和医疗救治措施,我国境内疫情 上升的势头得到一定程度的遏制,大多数省份疫情缓解,但境外的发病人数呈上升态势。随着对疾病临床表现、病理认识的 深入和诊疗经验的积累,为进一步加强对该病的早诊早治,提 高治愈率,降低病亡率,最大可能避免医院感染,同时提醒注意境外输入性病例导致的传播和扩散,我们对《新型冠状病毒 肺炎诊疗方案(试行第六版)》进行修订,形成了《新型冠状病 毒肺炎诊疗方案(试行第七版)》。01 PART 病原学特点新型冠状病毒属于 β属的冠状病毒,有包膜,颗粒呈圆形 或椭圆形,常为多形性,直径60-140nm。其基因特征与SARS-CoV 和MERS-CoV有明显区别(第6版为SARSr-CoV 和MERSr-CoV)。目前研究显示与蝙蝠SARS样冠状病 毒(bat-SL-CoVZC45)同源性达85%以上。体外分离培养时,新 型冠状病毒96个小时左右即可在人呼吸道上皮细胞内发现,而 在Vero E6和Huh-7细胞系中分离培养需约6天。对冠状病毒理化特性的认识多来自对SARS-CoV和MERS-CoV 的研究。病毒对紫外线和热敏感,56°C 30分钟、乙醚、75%乙醇、含氯消毒剂、过氧乙酸和氯仿等脂溶剂均可有效灭活病毒, 氯己定不能有效灭活病毒。02 PART 流行病学特点(一) 传染源。目前所见传染源主要是新型冠状病毒感染的患者。无症状 感染者也可能成为传染源。(二) 传播途径。经呼吸道飞沫和密切接触传播是主要的传播途径。在相对封闭的环境中长时间暴露于高浓度气溶胶情况下存在经气溶胶 传播的可能。增加:由于在粪便及尿中可分离到新型冠状病毒,应注 意粪便及尿对环境污染造成气溶胶或接触传播。(三) 易感人群。人群普遍易感。03 PART 病理改变本章节全部为新增,请留意根据目前有限的尸检和穿刺组织病理观察结果总结如下。(一)肺脏。肺脏呈不同程度的实变。肺泡腔内见浆液、纤维蛋白性渗出物及透明膜形成;渗出 细胞主要为单核和巨噬细胞,易见多核巨细胞。II型肺泡上皮 细胞显著增生,部分细胞脱落。II型肺泡上皮细胞和巨噬细胞 内可见包涵体。肺泡隔血管充血、水肿,可见单核和淋巴细胞 浸润及血管内透明血栓形成。肺组织灶性出血、坏死,可出现 出血性梗死。部分肺泡腔渗出物机化和肺间质纤维化。肺内支气管黏膜部分上皮脱落,腔内可见黏液及黏液栓形成。少数肺泡过度充气、肺泡隔断裂或囊腔形成。电镜下支气管黏膜上皮和II型肺泡上皮细胞胞质内可见冠 状病毒颗粒。免疫组化染色显示部分肺泡上皮和巨噬细胞呈新 型冠状病毒抗原阳性,RT-PCR检测新型冠状病毒核酸阳性。(二)脾脏、肺门淋巴结和骨髓。脾脏明显缩小。淋巴细胞数量明显减少,灶性出血和坏死, 脾脏内巨噬细胞增生并可见吞噬现象;淋巴结淋巴细胞数量较少,可见坏死。免疫组化染色显示脾脏和淋巴结内CD4+T和CD8+T 细胞均减少。骨髓三系细胞数量减少。(三)心脏和血管。心肌细胞可见变性、坏死,间质内可见少数单核细胞、淋巴细胞和(或)中性粒细胞浸润。部分血管内皮脱落、内膜炎症及血栓形成。(四) 肝脏和胆囊。体积增大,暗红色。肝细胞变性、灶性坏死伴中性粒细胞浸润;肝血窦充血,汇管区见淋巴细胞和单核细胞细胞浸润, 微血栓形成。胆囊高度充盈。(五) 肾脏。肾小球球囊腔内见蛋白性渗出物,肾小管上皮变性、脱落, 可见透明管型。间质充血,可见微血栓和灶性纤维化。(六) 其他器官。脑组织充血、水肿,部分神经元变性。肾上腺见灶性坏死。食管、胃和肠管黏膜上皮不同程度变性、坏死、脱落。04 PART 临床特点(一)临床表现。基于目前的流行病学调查,潜伏期1~14天,多为3~7天。以发热、干咳、乏力为主要表现。少数患者伴有鼻塞、流 涕、咽痛、肌痛和腹泻等症状。重症患者多在发病一周后出现 呼吸困难和/或低氧血症,严重者可快速进展为急性呼吸窘迫综 合征、脓毒症休克、难以纠正的代谢性酸中毒和出凝血功能障 碍及多器官功能衰竭等。值得注意的是重型、危重型患者病程

高流量鼻导管氧疗或无创机械通气:当患者接受标准氧疗后呼吸窘迫和/或低氧血症无法缓解时,可考虑使用高流量鼻导管氧疗或无创通气。若短时间(1-2小时)内病情无改善甚至恶化,应当及时进行气管插管和有创机械通气。(3) 有创机械通气:釆用肺保护性通气策略,即小潮气量 (6-8mL/kg理想体重)和低水平气道平台压力(平台压<30cmH2O)进行机械通气,以减少呼吸机相关肺损伤。新增:在保证气道平台压W 35cmH2O时,可适当釆用高PEEP,保持气道温化湿化,避免长时间镇静,早期唤醒患者并进行肺康复治疗。较多患者存在人机不同步,应当及时使用镇静以及肌松剂。新增:根据气道分泌物情况, 选择密闭式吸痰,必要时行支气管镜检查釆取相应治疗。(4) 挽救治疗:对于严重ARDS患者,建议进行肺复张。在人力资源充足的情况下,每天应当进行12小时以上的俯卧位通气。俯卧位机械通气效果不佳者,如条件允许,应当尽快考虑体外膜肺氧合(ECMO)。新增:其相关指征:①在FiO2>90%时,氧 合指数小于80mmHg,持续3-4小时以上;②气道平台压≥35cmH2O。单纯呼吸衰竭患者,首选VV-ECMO模式;若需要循环 支持,则选用VA-ECMO模式。在基础疾病得以控制,心肺功能 有恢复迹象时,可开始撤机试验。3. 循环支持:在充分液体复苏的基础上,改善微循环,使用血管活性药物,新增:密切监测患者血压、心率和尿量的变化,以及动脉血气分析中乳酸和碱剩余,必要时进行无创或有创血流 动力学监测,如超声多普勒法、超声心动图、有创血压或持续 心排血量(PiCCO)监测。在救治过程中,注意液体平衡策略,避免过量和不足。新增:如果发现患者心率突发增加大于基础值的20%或血压下降大约基础值20%以上时,若伴有皮肤灌注不良和尿量减少等表现时,应密切观察患者是否存在脓毒症休克、消化道出血或心功能衰竭等情况。新增:4. 肾功能衰竭和肾替代治疗:危重症患者的肾功能损伤应 积极寻找导致肾功能损伤的原因,如低灌注和药物等因素。对 于肾功能衰竭患者的治疗应注重体液平衡、酸碱平衡和电解质 平衡,在营养支持治疗方面应注意氮平衡、热量和微量元素等 补充。重症患者可选择连续性肾替代治疗(continuous renal replacement therapy, CRRT)。其指征包括:①高钾血症;② 酸中毒;③肺水肿或水负荷过重;④多器官功能不全时的液体管理。5. 康复者血浆治疗:适用于病情进展较快、重型和危重型患者。用法用量参考《新冠肺炎康复者恢复期血浆临床治疗方案(试行第二版)》。新增:6. 血液净化治疗:血液净化系统包括血浆置换、吸附、灌流、血液/血浆滤过等,能清除炎症因子,阻断“细胞因子风暴”, 从而减轻炎症反应对机体的损伤,可用于重型、危重型患者细 胞因子风暴早中期的救治。7. 免疫治疗:对于双肺广泛病变者及重型患者,且实验室检测IL-6水平升高者,可试用托珠单抗治疗。首次剂量 4-8mg/kg,推荐剂量为400mg、0. 9%生理盐水稀释至100ml,输 注时间大于1小时;首次用药疗效不佳者,可在12小时后追加 应用一次(剂量同前),累计给药次数最多为2次,单次最大剂 量不超过800mg。注意过敏反应,有结核等活动性感染者禁用。8. 其他治疗措施 :对于氧合指标进行性恶化、影像学进展迅速、机体炎症反 应过度激活状态的患者,酌情短期内(3〜5日)使用糖皮质激素,建议剂量不超过相当于甲泼尼龙1〜2mg/kg/日,应当注意较大剂量糖皮质激素由于免疫抑制作用,会延缓对冠状病毒的清除;可静脉给予血必净100ml/次,每日2次治疗;可使用肠道微生态调节剂,维持肠道微生态平衡,预防继发细菌感染。(删除部分和上面新增重复内容)新增:儿童重型、危重型病例可酌情考虑给予静脉滴注丙种球蛋白。患有重型或危重型新型冠状病毒肺炎的孕妇应积极终止妊娠,剖腹产为首选。患者常存在焦虑恐惧情绪,应当加强心理疏导。(四)中医治疗。本病属于中医“疫”病范畴,病因为感受“疫戾"之气,各地可根据病情、当地气候特点以及不同体质等情况,参照下列方案进行辨证论治。涉及到超药典剂量,应当在医师指导下使用。1
