Lung transplantation has been proved to be an effective treatment after more than forty years of fast development, while more than 4000 cases of lung transplantation performed globally each year. Recently, lung transplantation in China has been advanced rapidly, and the number of transplants has increased year by year. Respiratory and Critical Care Medicine team has been recognized to play a crucial role in lung transplantation. It has an irreplaceable role and status in promoting lung transplantation, improving the preoperative evaluation of lung transplantation and the maintenance of donors, and carrying out perioperative management, as well as long-term follow-up. Lung transplantation is a systematic project, requiring the perfect cooperation and collaboration of team members and contributing to recipients’ recovery.
ObjectiveTo investigate the clinical characteristics and contribution factors in severe coronavirus disease 2019 (COVID-19).MethodsThe clinical symptoms, laboratory findings, radiologic data, treatment strategies, and outcomes of 110 COVID-19 patients were retrospectively analyzed in these hospitals from Jan 20, 2020 to Feb 28, 2020. All patients were confirmed by fluorescence reverse transcription polymerase chain reaction. They were classified into a non-severe group and a severe group based on their symptoms, laboratory and radiologic findings. All patients were given antivirus, oxygen therapy, and support treatments. The severe patients received high-flow oxygen therapy, non-invasive mechanical ventilation, invasive mechanical ventilation or extracorporeal membrane oxygenation. The outcomes of patients were followed up until March 15, 2020. Contribution factors of severe patients were summarized from these clinical data.ResultsThe median age was 50 years old, including 66 males (60.0%) and 44 females (40.0%). Among them, 45 cases (40.9%) had underlying diseases, and 108 cases (98.2%) had different degrees of fever. The common clinical manifestations were cough (80.0%, 88/110), expectoration (33.6%, 37/110), fatigue (50.0%, 55/110), and chest tightness (41.8%, 46/110). Based on classification criteria, 78 (70.9%) non-severe patients and 32 (29.1%) severe patients were identified. Significant difference of the following parameters was found between two groups (P<0.05): age was 47 (45, 50) years vs. 55 (50, 59) years (Z=–2.493); proportion of patients with underlying diseases was 27 (34.6%) vs. 18 (56.3%) (χ2=4.393); lymphocyte count was 1.2 (0.9, 1.5)×109/L vs. 0.6 (0.4, 0.7)×109/L (Z=–7.26); C reactive protein (CRP) was 16.2 (6.5, 24.0) mg/L vs. 45.3 (21.8, 69.4) mg/L (Z=–4.894); prothrombin time (PT) was 15 (12, 19) seconds vs. 18 (17, 19) seconds (Z=–2.532); D-dimer was 0.67 (0.51, 0.82) mg/L vs. 0.98 (0.80, 1.57) mg/L (Z=–5.06); erythrocyte sedimentation rate (ESR) was 38.0 (20.8, 59.3) mm/1 h vs. 75.5 (39.8, 96.8) mm/1 h (Z=–3.851); lactate dehydrogenase (LDH) was 218.0 (175.0, 252.3) U/L vs. 325.0 (276.5, 413.5) U/L (Z=–5.539); neutrophil count was 3.1 (2.1, 4.5)×109/L vs. 5.5 (3.7, 9.1)×109/L (Z=–4.077). Multivariable logistic analysis showed that there was positive correlation in elevated LDH, CRP, PT, and neutrophil count with the severity of the disease. Currently, 107 patients were discharged and 3 patients died. Total mortality was 2.7%.ConclusionsOld age, underlying diseases, low lymphocyte count, elevated CPR, high D-dimer and ESR are relevant to the severity of COVID-19. LDH, CPR, PT and neutrophil count are independent risk factors for the prognosis of COVID-19.
ObjectiveTo summarize our experience of critical congenital heart diseases treatment system for the newborn and to report its surgical results.MethodsWe reviewed the clinical data of 97 neonates with congenital heart diseases who admitted to pediatric cardiac center from January 2019 to August 2020 in our hospital. The patients were divided into a prenatal and postnatal diagnosis and treatment integration group (integrated group, n=41), and a postnatal diagnosis and rapid admission by green channel group (non-integrated group, n=56).ResultsThe age of admission in the integrated group was younger than that in the non-integrated group (3.0 d vs. 11.0 d, P<0.001), and the weight was lighter (3.3±0.4 kg vs. 3.6±0.6 kg, P=0.006), operation age was younger (13.0 d vs. 17.5 d, P=0.004), proportion of palliative surgery was smaller (2.4% vs. 8.9%, P=0.396), time for ventilator assistance was longer (153.0 h vs. 65.0 h, P=0.020), hospital mortality was lower (0.0% vs. 7.1%, P=0.135). There was no significant difference in the follow-up (11.0 months vs. 12 months, P=1.000), out-of-hospital mortality (2.4% vs. 1.8%, P=1.000) and total mortality (2.4% vs. 8.9%, P=0.396) between the two groups.ConclusionPrenatal and postnatal diagnosis and treatment integration can significantly shorten the diagnosis and the hospitalization interval of newborn, that surgical intervention could be performed timely. It can reduce the risk of death before surgery but need longer time for recovery after surgery. Patients with postnatal diagnosis and admitted hospital through green channel also can get perfect results if surgical intervention is performed timely.
Massive and severe cerebral infarction can lead to a high mortality and disability rate, and it is the bottleneck of preventing and treating cerebrovascular disease. Once the malignant brain edema of massive cerebral infarction or the critical status of severe cerebral infarction occurs, the treatment effect is very poor. Therefore, we should not only focus on the treatment of critical cerebral infarction, but also prevent its occurrence. It is clinically important to prevent the occurrence of this critical condition in advance and to prevent the occurrence of massive cerebral infarction and severe cerebral infarction. This article points out that some patients with massive or severe cerebral infarction can be prevented from becoming critically ill. The definition, key risk factors and corresponding prevention and treatment strategies of critical cerebral infarction have also been proposed. Critical cerebral infarction can be divided into two categories with or without malignant brain edema, and the risk factors and prediction and prevention strategies by categories andphases can be studied separately.
In order to identify the incidence of nosocomial pulmonary infection in surgical critical care patients in our hospital, we studied 800 patients discharged from surgical intensive care unit between May 1992 to Dec. 1994. One hundred and six episodes of pulmonary infection were found in 96 cases, in which 20 cases had been re-infected. The infection rate was 12.0%. The age of patients, APACHE- Ⅱ score and duration in ICU were closely related to the incidence of pulmonary infection. Tracheal intubation, tracheotomy and mechanical ventilation were the predisposing factors. The prevalent pathogens were pseudomonas aeruginosa, acinetobacter, staphylococcus aureus and candida albicans. 54.7% of cases were infected with more than one pathogens, and 36.8% of cases had fungal infection. The prevention and treatment are also discussed.
Objective To investigate the relationship between the gastrointestinal function and ventilator-associated pneumonia (VAP) in critically ill patients who underwent invasive mechanical ventilation. Methods One-hundred and fifty-three cases of critically ill patients receiving mechanically ventilation were recruited in the study. After 5 days of ventilation, the gastrointestinal function score and the C-reactive protein (CRP) of each patient were recorded. The incidence of VAP was recorded during hospitalization. According to the incidence of VAP, all patients were divided intoaVAP group and a non-VAP group. The relationship between gastrointestinal function score and the incidence of VAP was analyzed. The relationship between CRP level and severity degree of VAP was also analyzed. Results VAP occurred in 42 cases with the incidence of 27.45%. The gastrointestinal function score (1.9±1.0 vs. 0.8±1.0, P < 0.05) and CRP level [(52.38±12.06) mg/L vs. (36.69±11.08)mg/L, P < 0.05] were both higher in the VAP group than those in the non-VAP group. At gastrointestinal function score of 0 - 3, the CRP levels were all higher in the VAP group than those in the non-VAP group (P < 0.05). The incidence of VAP was 8.33%, 23.68%, 45.45%, and 59.09% at gastrointestinal function score of 0, 1, 2 and 3, respectively, with significant differences between each other(P < 0.05). Conclusion For critically ill patients receiving invasive mechanical ventilation, the more severe the damage of gastrointestinal function is, the higher the incidence of VAP is, and the more serious the disease is.
