Objective This consensus aims to provide evidence-based recommendations on common questions in the diagnosis and treatment of acute respiratory failure (ARF) for critically ill cancer patients.Methods We developed six clinical questions using the PICO (Population, Intervention, Comparison, and Outcome) principle in diagnosis and treatment for critical ill cancer patients with ARF. Based on literature searching and meta-analyses, recommendations were devised. The GRADE (Grading of Recommendation Assessment, Development and Evaluation) method was applied to each question to reach consensus in the expert panel. Results The panel makes strong recommendations in favor of (1) metagenomic next-generation sequencing (mNGS) tests may aid clinicians in rapid diagnosis in critically ill cancer patients suspected of pulmonary infections; (2) extracorporeal membrane oxygenation (ECMO) therapy should not be used as a routine rescue therapy for acute respiratory distress syndrome in critically ill cancer patients but may benefit highly selected patients after multi-disciplinary consultations; (3) cancer patients who have received immune checkpoint inhibitor therapy have an increased incidence of pneumonitis compared with standard chemotherapy; (4) critically ill cancer patients who are on invasive mechanical ventilation and estimated to be extubated after 14 days may benefit from early tracheotomy; and (5) high-flow nasal oxygen and noninvasive ventilation therapy can be used as a first-line oxygen strategy for critically ill cancer patients with ARFs. A weak recommendation is: (6) for critically ill cancer patients with ARF caused by tumor compression, urgent chemotherapy may be considered as a rescue therapy only in patients determined to be potentially sensitive to the anticancer therapy after multidisciplinary consultations. Conclusions The recommendations based on the available evidence can guide diagnosis and treatment in critically ill cancer patients with acute respiratory failure and improve outcomes.

Acute severe ammonia inhalation can seriously affect oxygenation and ventilation function of patients, and even cause acute respiratory distress syndrome (ARDS). Extracorporeal membrane oxygenation (ECMO) technology is increasingly used in treating patients with ARDS caused by infection, cardiogenic shock, trauma, and drowning with achieved certain effects, but its usage for ARDS caused by ammonia is rarely reported. On July 7, 2018, a case of ARDS caused by ammonia inhalation was admitted to the emergency ICU of the First Affiliated Hospital of Zhengzhou University. After admission, the patient was treated with ECMO immediately on the basis of anti-infection, anti-oxidation, suctioning and nebulization treatments. After 8 days, he was weaned from ECMO and transferred to a general ward for continued rehabilitation. After 23 days, his condition improved and was discharged without complaining of any discomfort during the follow-up till March 2019. The successful experience was summarized in order to provide reference for the treatment of such patients in the future.

OBJECTIVE: To observe the therapeutic effect of acupuncture combined with western conventional therapy on type Ⅱ respiratory failure of acute exacerbation of chronic obstructive pulmonary disease (AECOPD) and evaluate the effect of acupuncture on diaphragmatic function and prognosis by bedside ultrasound. METHODS: A total of 111 patients with AECOPD type Ⅱ respiratory failure were randomized into an acupuncture group, a conventional treatment group and a non-acupoint acupuncture group, 37 cases in each one. The routine AECOPD nursing care and treatment with western medicine were provided in the 3 groups. Additionally, in the acupuncture group, acupuncture was applied at Dingchuan (EX-B 1), Feishu (BL 13), Taiyuan (LU 9), Danzhong (CV 17) and Zhongwan (CV 12), etc. In the non-acupoint acupuncture group, acupuncture was given at the points 5 to 10 mm lateral to each of the acupoints selected in the acupuncture group. Acupuncture was given once every day, 30 min each time, consecutively for 10 days in the above two groups. Separately, before treatment, on day 3, 7 and 10 of treatment, arterial partial pressure of oxygen (PaO RESULTS: On day 3, 7 and 10 of treatment, PaO CONCLUSION Acupuncture as adjunctive therapy achieves significant therapeutic effect on AECOPD type Ⅱ respiratory failure. It improves diaphragmatic function, promotes oxygenation and relieves carbon dioxide retention of artery, alleviates clinical symptoms and reduces the time of mechanic ventilation and hospitalization. Besides, the bedside ultrasound detection can objectively reflect the effect of acupuncture on diaphragmatic function in the patients with AECOPD complicated with typeⅡrespiratory failure.

OBJECTIVETo evaluate the value of noninvasive intermittent positive-pressure ventilation (NIPPV) in treatment of patients with pneumoconiosis combined with respiratory failure.

METHODThree were 46 inpatients with pneumoconiosis combined with respiratory failure. Twenty-six inpatients treated with conventional therapy and NIPPV were categorized as treatment group; Twenty inpatients just treated by conventional therapy served as control group. Compared with the changes of HR, RR and arterial blood gas index (PH, PaCO2, PaO2) in two groups after treatment.

RESULTSThe effective ratio of treatment group was 88.5%, control group was 60%, which had significant difference (P < 0.05); The HR in treatment group after treatment was (95.38 +/- 10.75) beats per minute, control group was [(103.00 +/- 12.56) beats per minute; The RR in treatment group was (21.69 +/- 1.37) breaths per minute, control group was [(22.60 +/- 1.57) breaths per minute]; The PaCO2 in treatment group was (52.88 +/- 10.75)mm Hg, control group was [(59.66 +/- 11.49)mm Hg]; All of those were significantly decreased than those in control group (P < 0.05). The PaO2 in treatment group was (100.77 +/- 25.3) mm Hg, control group was [(71.82 +/- 17.94) mmHg]; Compared with the control group, PaO2 in the treatment group increased significantly (P < 0.05).

CONCLUSIONNIPPV is beneficial to pneumoconiosis combined with respiratory failure in different degrees.

Recombinant activated factor VII (rFVIIa) is a novel therapeutic agent for life-threatening massive gastrointestinal bleeding. We report a case of massive gastrointestinal bleeding in a 78-year-old female patient with respiratory and renal failure. After failure of management of the bleeding with routine pharmacotherapy, we gave the patient rFVIIa injection at the dose of 20 µg/kg and the bleeding was rapidly controlled. Adverse side effects of the drug were not observed in this patient.

Thrombolytic therapy is usually reserved for patients with clinically serious or massive pulmonary embolism. In desperated cases, however, pulmonary embolectomy is recommended despite its high mortality rate. We experienced acute respiraory failure after embolectomy performed under cardiopulmonary bypass in patient with chronic massive pulmonary embolism. The patient recovered sucessfully with postoperative management in the intensive care unit.

OBJECTIVEAcute interstitial pneumonia (AIP) is a rare lung interstitial disease in children. This study was conducted to understand the clinical features of the AIP in children.

METHODThe data of the three cases with AIP admitted to our hospital from March 2008 to November 2009 were reviewed. Of the 3 cases, 2 were male, one was female. Their age ranged from 1 year and 4 months to 10 years. The clinical manifestation, pulmonary function test and the high resolution computed tomography (HRCT) and pathology of the lung were studied retrospectively. Tissue specimens of the lung were obtained by video-assisted thoracoscopic biopsy. Viral etiologic examinations for the respiratory syncytial virus, adenovirus, influenza virus, parainfluenza viruses, EB virus, cytomegalovirus, enterovirus and herpes simplex virus were performed. The IgM antibody to Mycoplasma pneumoniae in the serum was also detected.

RESULTAll the 3 cases rapidly developed respiratory failure of unknown origin, none of these cases had failure of any other organs. All three cases had cough and dyspnea. No case had the rales and digital clubbing. The examinations for viruses, bacteria and Mycoplasma pneumoniae infection were all negative. No evidence for the diagnosis of connective tissue disease was obtained. The HRCT of the chest showed diffuse alveolar consolidation, air bronchogram and ground glass appearance in the bilateral lungs, and the traction-associated bronchiectasis in areas. All the three cases had the histological proof of diffuse alveolar damage by the biopsy. All the three cases were treated with CPAP and corticosteroid. Two cases were treated with corticosteroid in early stage of the disease, the condition of these cases were improved obviously. The third case was treated with high-dose steroid pulse therapy days, the condition of this case was improved slightly in a month. One year follow-up showed that case 1 and case 2 had no hypoxemia and the HRCT of the chest showed obvious improvement. The pulmonary function of case 2 had restrictive deficiency.

CONCLUSIONAIP has a rapidly progressive clinical course leading to respiratory failure. The HRCT of the chest showed alveolar consolidation and ground glass-like change. The pathology of the lung includes diffuse alveolar damage. The prognosis of the AIP in children may be improved by the treatment with respiratory assistance and corticosteroids.
