ABSTRACT
Objective:To investigate the relationship between intestinal flora and acute respiratory distress syndrome in patients with severe acute pancreatitis.Methods:One hundred and six patients with severe acute pancreatitis admitted to a hospital from March 2019 to February 2021 were selected as the observation group for prospective analysis. They were divided into concurrent group (52 cases) and non-concurrent group (54 cases) according to whether they were complicated with acute respiratory distress syndrome. In addition, 100 healthy people in the same period were selected as the control group to analyze the relationship between intestinal flora and acute respiratory distress syndrome in patients with severe acute pancreatitis.Results:There were significant differences in the number of intestinal flora ( Lactobacillus, Bifidobacterium, Escherichia coli) between the observation group and the control group ( t = 49.69, 73.28 and 46.32; P<0.05). There were significant differences in the number of intestinal flora ( Lactobacillus, Bifidobacterium, Escherichia coli) between the concurrent group and the non-concurrent group ( t = 34.85, 39.71 and 23.47; P<0.05). The levels of serum endotoxin, diamine oxidase and D-lactic acid in the concurrent group were significantly higher than those in the non-concurrent group: (0.63 ± 0.16) EU/ml vs. (0.45 ± 0.08) EU/ml, (6.29 ± 1.18) U/ml vs. (4.89 ± 0.91) U/ml, (11.63 ± 2.84) mmol/L vs. (9.33 ± 2.61) mmol/L ( t = 7.37, 6.85 and 4.34, P<0.05). Spearman analysis showed that severe acute pancreatitis complicated with acute respiratory distress syndrome was negatively correlated with the number of intestinal Lactobacillus and Bifidobacterium ( r = - 0.342 and - 0.291, P = 0.011 and 0.021), which was positively correlated with the number of intestinal Escherichia coli flora ( r = 0.263, P = 0.033). Conclusions:Intestinal colony imbalance is common in patients with severe acute pancreatitis, and the imbalance of intestinal colony and the impairment of intestinal mucosal barrier function are more serious in patients with acute respiratory distress syndrome. There is a significant correlation between severe acute pancreatitis complicated with acute respiratory distress syndrome and its intestinal colony.
ABSTRACT
Objective:To evaluate the value of the ROX index [blood oxygen saturation (SpO 2)/fraction of inspiration O 2 (FiO 2)/respiratory rate (RR)], ROX-heart rate (HR) index (ROX index/HR × 100), modified ROX (mROX) index [partial pressure of oxygen in the blood (PaO 2)/FiO 2/RR], and mROX-HR index (mROX index/HR × 100) in predicting prognosis for patients with acute respiratory distress syndrome (ARDS) treated with high-flow nasal cannula oxygen therapy (HFNC). Methods:The clinical data of 100 patients with ARDS who received HFNC between January 2018 and December 2022 at The Third People's Hospital of Hubei Province, Jianghan University, were retrospectively analyzed. These patients were divided into two groups based on whether HFNC treatment was successful or not: a success group with 65 patients and a failure group with 35 patients. The differences in the ROX index, ROX-HR index, mROX index, and mROX-HR index in the observation group were observed at the designated time points: 2, 12, and 24 hours after HFNC treatment. Receiver operating characteristic (ROC) curves were utilized to evaluate the value of ROX index, ROX-HR index, mROX index, and mROX-HR index in predicting the success or failure of HFNC treatment at 2, 12, and 24 hours. Cutoff values were determined.Results:There were no significant differences in age, gender, body mass index, Acute Physiology and Chronic Health Evaluation (APACHE II) score, Sequential Organ Failure Assessment score, or the proportions of underlying diseases and pulmonary causes between the success and failure groups (all P > 0.05). Furthermore, there were no significant differences in baseline HR, RR, FiO 2, SpO 2, partial pressure of carbon dioxide (PaCO 2), PaO 2, pH, lactate, oxygenation index, ROX index, mROX index, ROX-HR index, or mROX-HR index between the two groups (all P > 0.05). The ROX index in the success group at 2, 12, and 24 hours after HFNC treatment was 6.86 ± 1.09, 6.31 ± 1.61, and 8.24 ± 2.29, respectively. These values were significantly higher than those in the failure group (6.36 ± 0.67, 5.65 ± 1.44, and 5.41 ± 0.84) at the corresponding time points ( F = 5.97, 4.04, 49.40, all P < 0.05). At 2, 12, and 24 hours after HFNC treatment, the mROX index in the success group was 5.94 ± 1.28, 5.74 ± 1.23, and 8.51 ± 2.64, respectively. These values were significantly higher than those in the failure group (5.26 ± 0.74, 4.80 ± 0.97, 4.81 ± 1.17) at the corresponding time points ( F = 8.23, 15.38, 61.79, all P < 0.05). At 2, 12, and 24 hours after HFNC treatment, the ROX-HR index in the success group was 6.53 ± 1.32, 6.85 ± 1.44, and 7.57 ± 1.47, respectively. These values were significantly higher than those in the failure group (5.79 ± 1.04, 5.87 ± 1.03, 5.57 ± 0.63) at the corresponding time points ( F = 8.28, 12.61, 58.34, all P < 0.05). At 2, 12, and 24 hours after HFNC treatment, the mROX-HR index in the success group was 6.11 ± 1.30, 6.86 ± 1.13, and 7.79 ± 1.79, respectively. These values were significantly higher than those in the failure group (5.20 ± 1.06, 5.66 ± 1.46, 4.92 ± 0.90) at the corresponding time points ( F = 12.60, 20.87, 78.56, all P < 0.05). The receiver operating characteristic curve analysis revealed that the optimal thresholds were 6.56, 6.02, 6.24, and 5.25 for the ROX index, mROX index, ROX-HR index, and mROX-HR index, respectively. The area under the curve (AUC) values were 0.63, 0.66, 0.68, and 0.72, with sensitivity of 55.4%, 47.7%, 56.9%, and 76.9%, and specificity of 71.4%, 91.4%, 77.1%, and 62.9%, respectively. At 12 hours after treatment, the optimal thresholds were 6.09, 5.53, 6.52, and 5.99, with AUC values of 0.62, 0.70, 0.67, and 0.80, sensitivity of 55.4%, 53.8%, 61.5%, and 80.0%, and specificity of 74.3%, 77.1%, 71.4%, and 74.3%, respectively. At 24 hours after treatment, the optimal thresholds were 6.23, 6.4, 5.99, and 6.22, with AUC values of 0.88, 0.90, 0.91, and 0.93, sensitivity of 81.5%, 80.0%, 87.7%, and 83.1%, and specificity of 91.4%, 94.3%, 80.0%, and 91.4%, respectively. Conclusion:The use of the ROX index, mROX index, ROX-HR index, and mROX-HR index can aid in predicting the prognosis of ARDS patients. The predictive value of these indices increases as treatment time progresses. The mROX-HR index offers marked advantages during the initial stages of treatment and could serve as a reliable early predictor.
ABSTRACT
Objective:To investigate the efficacy of plasma exchange (PE) in treatment of patients with acute respiratory distress syndrome (ARDS).Methods:Forty-two patients who met the inclusion criteria in the intensive care unit of Chenzhou First People′s Hospital were randomly divided into control group and plasma exchange (PE) group with 21 cases in each group. The control group received conventional treatment; while the PE group received conventional treatment plus PE. The mechanical ventilation time (MVT), length of ICU stay (ICU LOS), 28-day mortality and 90-day mortality of patients were analyzed. The oxygenation index, SOFA score, norepinephrine (NE) dose, C-reactive protein (CRP), procalcitonin (PCT) and IL-6 levels were evaluated before and after treatment.Results:In the control group the oxygenation index, IL-6, PCT and CRP were significantly improved after treatment ( t=-4.50, 2.46, Z=-3.53, t=5.55, all P<0.05), but the SOFA score and NE dose were not significantly changed ( t=1.98, Z=-0.47,all P>0.05). In the PE group, the oxygenation index, SOFA score, IL-6, PCT, CRP were significantly improved and the NE dose was reduced after treatment ( t=2.18, 9.23, 5.26, Z=-3.77, t=7.27 and Z=-2.54,all P<0.05). The oxygenation index, SOFA score, IL-6, CRP were significantly better after treatment and NE dose was lower in PE group than those in the control group ( t=2.18, -2.21, -2.12, -2.61 and Z=-2.11, all P<0.05). Compared with the control group, the MVT(14.0±5.2d vs. 18.4±6.3d), ICU LOS(19.3±4.9d vs. 23.2±7.3d) and 28-day mortality (14.3%(3/21) vs. 42.8%(10/21)) in the PE group were significantly decreased ( t=-2.48, -2.04 and χ2=4.20,all P<0.05). There was no significant difference in the 90-d mortality between the two groups (28.6%(6/21) vs. 52.4%(11/21), χ2=2.47, P=0.208). Conclusion:Therapeutic plasma exchange can significantly reduce the inflammatory response, improve the organ function and reduce the short-term mortality of ARDS patients.

ABSTRACT
El uso compasivo de ruxolitinib en la covid-19 demostró una mejoría en las imágenes de tórax y mayor número de altas en el grupo que lo usó vs. el grupo 1 (cloroquinas y azitromicina), con descenso de los marcadores inflamatorios. Existe un artículo que señaló que un caso que fue refractario a la terapia anti-IL6, pero respondió a la inhibición de Jak-Stat con ruxolitinib.1 La comorbilidad más frecuente en ambos grupos fue la hipertensión arterial, seguida por la diabetes tipo 2; el grupo 1 presentó un mayor número de pacientes que no presentaban comorbilidades (18 pacientes). El número de hombres con enfermedad por SARS-CoV2 fue mayor en el grupo 1, con 31 hombres (62,0%) frente un total de 19 mujeres (38,0%), mientras que, en el grupo 2, el 25,0% eran hombres y mujeres, el 25,0%. La gravedad de la covid-19 fue definida como moderada: adolescente o adulto con signos clínicos de neumonía (fiebre, tos, disnea, taquipnea), en particular SpO2 ≥ 90% con aire ambiente; y grave: adolescente o adulto con signos clínicos de neumonía (fiebre, tos, disnea, taquipnea) más alguno de los siguientes: frecuencia respiratoria > 30 inspiraciones/min, dificultad respiratoria grave o SpO2 < 90% con aire ambiente.2 El síndrome de dificultad respiratoria aguda (SDRA) en ambos grupos fue de un pro medio de relación entre la presión arterial de oxígeno y la fracción inspirada de oxígeno (PaFi) en el grupo ruxolitinib 135,3 mmHg vs. Grupo control PaFi 138,9 mmHg. Se definió la eficacia por descenso de los marcadores inflamatorios, mejoría gasométrica de la PaFi, menor requerimiento de oxígeno, disminución del ingreso a unidad de cuidados intensivos de los pacientes con sintomatología grave, demostración de la seguridad del fármaco en los 10 días posteriores a su uso y detallado del número de casos con alta médica.
The group with compassionate use of ruxolitinib for Covid-19 showed improved chest images and a larger number of discharged patients, compared to group 1 (chloro quines and azithromycin), with a decrease in inflammatory markers. There is one arti cle that described a case which refractory to anti-IL6 therapy but responded to Jak-Stat inhibition with ruxolitinib.1 The most common comorbidity in both groups was arterial hypertension, followed by diabetes type 2; group 1 showed a larger number of patients without comorbidities (18 patients). The number of male patients with the disease caused by SARS-CoV2 was larger in group 1, with 31 males (62.0%), compared to a total of 19 females (38.0%), whereas in group 2, 25.0% were males, and 25.0% females. The severity of Covid-19 was defined as moderate: adolescent or adult with clinical signs of pneumonia (fever, cough, dys pnea, tachypnea), particularly SpO2 ≥ 90% on ambient air; and severe: adolescent or adult with clinical signs of pneumonia (fever, cough, dyspnea, tachypnea) plus some of the following: respiratory rate > 30 breaths/min, severe respiratory distress or SpO2 < 90% on ambient air.2 The acute respiratory distress syndrome (ARDS) in both groups had an average ratio of pressure arterial oxygen and fraction of inspired oxygen (PaFi) of 135.3 mmHg in the ruxolitinib group versus 138.9 mmHg in the control group. Efficacy was defined as: decrease in inflammatory markers, gasometric improvement in the PaFi, lower oxygen requirement, lower number of patients with severe symptoms admitted to the Intensive Care Unit, proof of the drug's safety 10 days after use, and detailed number of discharged patients.

Abstract Introduction: Severe coronavirus disease 2019 (COVID-19) is characterised by hyperinflammatory state, systemic coagulopathies, and multiorgan involvement, especially acute respiratory distress syndrome (ARDS). We here describe our preliminary clinical experience with COVID-19 patients treated via an early initiation of extracorporeal blood purification combined with systemic heparinisation and respiratory support. Methods: Fifteen patients were included; several biomarkers associated with COVID-19 severity were monitored. Personalised treatment was tailored according to the levels of interleukin (IL)-6, IL-8, tumour necrosis factor alpha, C-reactive protein (CRP), neutrophil-to-lymphocyte ratio, thrombocyte counts, D-dimers, and fibrinogen. Treatment consisted of respiratory support, extracorporeal blood purification using the AN69ST (oXiris®) hemofilter, and 300 U/kg heparin to maintain activation clotting time ≥ 180 seconds. Results: Ten patients presented with severe to critical disease (dyspnoea, hypoxia, respiratory rate > 30/min, peripheral oxygen saturation < 90%, or > 50% lung involvement on X-ray imaging). The median intensive care unit length of stay was 9.3 days (interquartile range 5.3-10.1); two patients developed ARDS and died after 5 and 26 days. Clinical improvement was associated with normalisation (increase) of thrombocytes and white blood cells, stable levels of IL-6 (< 50 ng/mL), and a decrease of CRP and fibrinogen. Conclusion: Continuous monitoring of COVID-19 severity biomarkers and radiological imaging is crucial to assess disease progression, uncontrolled inflammation, and to avert irreversible multiorgan failure. The combination of systemic heparin anticoagulation regimens and extracorporeal blood purification using cytokine-adsorbing hemofilters may reduce hyperinflammation, prevent coagulopathy, and support clinical recovery.
ABSTRACT
Objective:To evaluate the effects of neuromuscular blocking agents (NMBA) on oxygenation and respiratory conditions in patients with acute respiratory distress syndrome(ARDS).Methods:English databases such as MEDLINE, Embase and Web of Science were searched online, as well as Chinese databases such as China National Knowledge Infrastructure (CNKI), Chinese Biomedical Literature Database and Wanfang Database. Randomized controlled trials (RCTs) of NMBA therapy for ARDS with publication date up to May 2020 were retrieved. Literature was screened according to inclusion and exclusion criteria, and the main analysis indicators were oxygenation index.Results:A total of 5 RCTs were included, and 1 462 ARDS patients were enrolled. Compared with the control group, the ratio of partial arterial oxygen pressure to fraction of inspired (PaO 2)/(FiO 2) significantly improved in the intervention group after 72 hours MD=14.39, (95 %CI 6.40-22.38, P=0.000 4) and 96 hours of NMBA, but there was no difference between PaO 2/FiO 2 at 24 and 48 hours ( P>0.05).Positive end expiratory pressure (PEEP) significantly decreased at 72 hours ( MD=-0.45, 95 %CI -0.87--0.03, P=0.04) and 96 hours ( MD=-0.82, 95 %CI -1.39--0.26, P=0.004) treatment with NMBA, while there was no significant difference in PEEP between 24 and 48 hours after treatment ( P>0.05). At 96 h, plateau pressure (Pplat) in the intervention group was significantly lower ( MD=-1.69, 95 %CI -2.64--0.75, P=0.000 4), and there was no significant difference in Pplat between 24, 48 and 72 h after treatment ( P>0.05). Conclusion:The early use of NMBA within 48 hours has a delayed improvement effect on oxygenation and ventilator conditions in ARDS patients.
ABSTRACT
Objective:To investigate the risk factors of postoperative acute respiratory distress syndrome (ARDS) in patients with esophageal cancer.Methods:The clinical data of patients with esophageal cancer who underwent surgery in the Affiliated Huai'an No. 1 People's Hospital of Nanjing Medical University from January 2020 to April 2021 were retrospectively analyzed, 223 patients were enrolled. The patients were divided into ARDS group (28 cases) and non-ARDS group (195 cases) according to whether ARDS occurred after surgery. The clinicopathological features of the two groups were compared, and the risk factors of postoperative ARDS were analyzed by univariate and multivariate logistic regression.Results:The age of patients in the ARDS group was higher than that in the non-ARDS group [(70±4) years old vs. (66±7) years old, P = 0.024]. The proportion of patients with history of chronic obstructive pulmonary disease (COPD) in the ARDS group was higher than that in the non-ARDS group [25.0% (7/28) vs. 4.6% (9/195), P < 0.001]. There were no statistical differences in gender, systolic pressure, body mass index, left ventricular ejection fraction, laboratory related examinations, history of smoking, history of diabetes, history of hypertension, history of cardiovascular disease, history of cerebrovascular disease, pathological type, tumor location, tumor stage and postoperative complications between the two groups (all P > 0.05). After further adjusting for gender, multivariate logistic regression analysis showed that the old age (≥65 years old) ( OR = 4.581, 95% CI 1.299-16.154, P = 0.018) and the history of COPD ( OR= 5.493, 95% CI 1.644-18.358, P = 0.006) were independent risk factors for postoperative ARDS in patients with esophageal cancer. Conclusions:Esophageal cancer patients with an age of ≥65 years old or history of COPD have a high risk of postoperative ARDS. Age and history of COPD may have certain significances in judging the occurrence of postoperative ARDS in patients with esophageal cancer.
ABSTRACT
Objective:To investigate the risk factors of severe chest trauma complicated by acute respiratory distress syndrome (ARDS).Methods:A case control study was conducted to analyze the clinical data of 120 patients with severe chest trauma admitted to 909th Hospital of Joint Logistics Support Force (Affiliated Dongnan Hospital of Xianmen University Medical College) from January 2018 to December 2020. There were 75 males and 45 females; aged 21-72 years [(42.2±4.8)years]. The causes of injury were traffic injury in 57 patients, crush injury in 21, fall injury in 21, smash injury in 11 and others in 10. There were 34 patients accompanied by fracture of the limb, spine and pelvis, 23 by abdominal organ injury and 8 by head trauma, with the exception of simple thoracic trauma in 55 patients. The patients were divided into ARDS group ( n=25) and non-ARDS group ( n=95) according to the condition of concurrent ARDS. The two groups were compared regarding the gender, age, causes of injury, respiratory rate, lung contusion, lung infection, flail chest, chest abbreviated injury scale (AIS), hemothorax, blood pressure, partial arterial oxygen pressure (PaO 2), initial central venous pressure (CVP) on admission, combined fracture of the limb, spine and pelvis, combined head injury and combined abdominal organ injury. The correlation between the above indexes and ARDS after severe chest trauma was analyzed by univariate analysis. Multivariate Logistic regression analysis was used to determine the independent risk factors for ARDS after severe chest trauma. Results:Univariate analysis showed a positive correlation of ARDS with age, respiratory rate, lung contusion, lung infection, flail chest, chest AIS, hemothorax, blood pressure, PaO 2, initial CVP on admission, combined fracture of the limb, spine and pelvis and combined abdominal organ injury ( P<0.05 or 0.01), but not with gender, causes of injury or combined head injury (all P>0.05). Multivariate Logistic regression analysis revealed that age ≥60 years ( OR=2.45, 95% CI 1.81-7.50, P<0.01), dyspnea (respiratory rate ≥28 times/minute or <10 times/minute) ( OR=9.55, 95% CI 2.26-9.38, P<0.01), lung contusion ( OR=6.78, 95% CI 1.84-6.96, P<0.01), lung infection ( OR=27.71, 95% CI 11.97-64.14, P<0.01), flail chest ( OR=8.97, 95% CI 2.29-14.97, P<0.01), chest AIS score ( OR=5.77, 95% CI 2.85-9.20, P<0.01), above medium amount of hemothorax ( OR=6.84, 95% CI 1.69-13.39, P<0.01), blood pressure <90 mmHg ( OR=7.93, 95% CI 1.64-11.84, P<0.01), PaO 2<60 mmHg ( OR=6.39, 95% CI 1.06-9.47, P<0.01) and absent initial CVP on admission ( OR=4.56, 95% CI 1.86-8.44, P<0.01) were significantly correlated with ARDS. Conclusion:Age ≥60 years, dyspnea (respiratory rate ≥28 times/minute or <10 times/minute), lung contusion, lung infection, flail chest, chest AIS, above medium l amount of hemothorax, blood pressure <90 mmHg, PaO 2<60 mmHg and absent initial CVP on admission are independent risk factors for ARDS in patients with severe chest trauma.
ABSTRACT
Objective:To investigate the effect of insulin secretion index (HOMA-β) in the evaluation of the condition of patients with acute respiratory distress syndrome (ARDS), multiple organ failure (MOF) and prognosis prediction.Methods:A retrospective analysis of the clinical data of 96 patients with ARDS hospitalized in Hangzhou Hospital of Zhejiang Medical Health Group from January 2019 to February 2021 was divided into MOF group (38 cases) and non-MOF group (58 cases). The baseline HOMA-β, oxygenation index, acute physiology and chronic health score Ⅱ (APACHE Ⅱ), sequential organ failure assessment (SOFA) and 28 d case fatality rate were collected and compared between the two groups. Compare the HOMA-β, oxygenation index, APACHE Ⅱ score, SOFA of ARDS patients with different survival prognosis. Logistic regression model analyzed the influence of HOMA-β, oxygenation index, APACHE Ⅱ, SOFA on the MOF and survival prognosis of ARDS patients. Pearson linear correlation method was used to analyze the relationship between HOMA-β and oxygenation index, APACHE Ⅱ, SOFA in ARDS patients. Receiver operating characteristic (ROC) curve was used to analyze the predictive power of HOMA-β on MOF and prognosis of ARDS patients.Results:The incidence of MOF and 28 d case fatality rate in 96 patients with ARDS were 39.58% (38/96) and 31.25% (31/96), respectively. The HOMA-β and oxygenation index in the MOF group were significantly lower than those in non-MOF group: 126.37 ± 28.75 vs. 178.52 ± 32.66, (125.41 ± 18.77) mmHg (1 mmHg = 0.133 kPa) vs. (153.62 ± 26.42) mmHg, while the APACHE Ⅱ, SOFA and 28 d case fatality rate were significantly higher than those in non-MOF group: (23.61 ± 4.68) points vs. (10.96 ± 2.85) points, (11.24 ± 1.65) points vs. (5.62 ± 0.87) points and 65.79% (25/38) vs. 10.34% (6/58), and there were statistical differences ( P<0.05). The HOMA-β and oxygenation index in dead ARDS patients were significantly lower than those in surviving ARDS patients: 89.62 ± 21.17 vs. 195.43 ± 35.64 and (121.66 ± 21.06) mmHg vs. (158.87 ± 28.71) mmHg, the APACHE Ⅱ and SOFA were significantly higher than those in surviving ARDS patients: (25.78 ± 5.42) points vs. (8.84 ± 2.51) points, (12.38 ± 1.22) points vs. (4.88 ± 0.83) points, and there were statistical differences ( P<0.05). Logistic regression model analysis showed that HOMA-β, oxygenation index, APACHE Ⅱ, SOFA of ARDS patients were all influencing factors of MOF and survival prognosis ( P<0.05). The results of Pearson linear correlation analysis showed that HOMA-β in ARDS patients was positively correlated with its oxygenation index ( P<0.05), and its APACHE Ⅱ and SOFA were negatively correlated ( P<0.05). ROC curve analysis results show that HOMA-β in ARDS patients has a high predictive power for their MOF and prognosis. Conclusions:The level of HOMA-β in ARDS patients is low, and it is closely related to its condition, MOF occurrence and survival prognosis. It can be used as a reference index for disease assessment and MOF and prognosis prediction of ARDS patients.

Introduction:Pre-term neonates have anatomophysiologicalsingularities predisposing them to respiratory complications such as Acute Respiratory Discomfort Syndrome. It is characterized by a deficit in pulmonary surfactant and consequent respiratory failure, increasing the need for invasive and non-invasive ventilatory support.Objective:To analyze the effects of non-invasive ventilation in premature newborns with Acute Respiratory Discomfort Syndrome. Methodology:In this integrative review, we used the following databases: SciELO, LILACS, PEDro, MEDLINE, and Bireme. Inclusion criteria were studies wrote in Portuguese and English and published between 2015 and 2020. Results:In the seven synthesized studies, ventilatory support systems were used: positive airway pressure at two levels: heated, humidified, and high-flow nasal cannulas; positive pressure ventilation in the nasal airways; and intermittent positive pressure ventilation. Two studies that used nasal cannulas showed less beneficial effects, and one reported similar outcome to the others, in addition to causing less nasal damage. Conclusions:Non-invasive ventilation had a significant reduction in the number of extubation failures in patients, especially in those who received positive pressure ventilation in the nasal airways and ventilation by positive intermittent nasal pressure (AU).

RESUMO Objetivo: Identificar a existência de associação entre os valores de driving pressure e mechanical power e do índice de oxigenação no primeiro dia de ventilação mecânica com a mortalidade de pacientes vítimas de trauma sem diagnóstico de síndrome do desconforto respiratório agudo. Métodos: Foram incluídos pacientes ventilados em modo de pressão ou volume controlado, com coleta de dados 24 horas após sua intubação orotraqueal. O acompanhamento do paciente foi realizado por 30 dias para obter o desfecho clínico. Os pacientes estiveram internados em duas unidades de terapia intensiva do Hospital de Pronto Socorro de Porto Alegre, no período de junho a setembro de 2019. Resultados: Foram avaliados 24 pacientes. Os valores de driving pressure, mechanical power e do índice de oxigenação foram similares entre os pacientes que sobreviveram e os que tiveram desfecho de óbito, sem diferença estatisticamente significativa entre os grupos. Conclusão: Os valores de driving pressure, mechanical power e índice de oxigenação obtidos no primeiro dia de ventilação mecânica não demonstraram ter associação com a mortalidade de pacientes vítimas de trauma sem síndrome do desconforto respiratório agudo.
ABSTRACT Objective: To identify the possible association between driving pressure and mechanical power values and oxygenation index on the first day of mechanical ventilation with the mortality of trauma patients without a diagnosis of acute respiratory distress syndrome. Methods: Patients under pressure-controlled or volume-controlled ventilation were included, with data collection 24 hours after orotracheal intubation. Patient follow-up was performed for 30 days to obtain the clinical outcome. The patients were admitted to two intensive care units of the Hospital de Pronto Socorro de Porto Alegre from June to September 2019. Results: A total of 24 patients were evaluated. Driving pressure, mechanical power and oxygenation index were similar among patients who survived and those who died, with no statistically significant difference between groups. Conclusion: Driving pressure, mechanical power and oxygenation index values obtained on the first day of mechanical ventilation were not associated with mortality of trauma patients without acute respiratory distress syndrome.

INTRODUÇÃO: O suspiro caracteriza-se pela realização de uma inspiração lenta e profunda, seguida de uma expiração lenta. Estudos sugerem que a adição de um suspiro por minuto em pacientes com síndrome do desconforto respiratório agudo, ventilados em PSV, melhora a oxigenação e a mecânica pulmonar. OBJETIVO: Avaliar o impacto da manobra de recrutamento alveolar através de suspiro na mecânica pulmonar e oxigenação em pacientes ventilados mecanicamente, além de verificar o impacto hemodinâmico e a incidência de intercorrências associadas à utilização da técnica. MATERIAIS E MÉTODOS: Estudo experimental com 17 pacientes em ventilação mecânica, apresentando relação entre pressão parcial de oxigênio alveolar e fração inspirada de oxigênio (PaO2/FiO2) inferior a 300mmHg. Avaliou-se dados respiratórios, de mecânica pulmonar e hemodinâmicos. Os dados foram coletados durante três períodos: antes do suspiro, imediatamente após e 15 minutos depois da técnica. Dois suspiros por minuto foram administrados utilizando pressão em vias aéreas limitada em 40cmH2O, durante um tempo inspiratório de quatro segundos. RESULTADOS: Após o suspiro, observou-se aumento da PaO2, pressão resistiva, complacência estática e relação PaO2/FiO2, além de diminuição da pressão de platô e pressão parcial de gás carbônico alveolar (PaCO2). Após 15 minutos da retirada do suspiro observou-se que a PaO2, pressão resistiva, complacência estática e relação PaO2/ FiO2 mantiveram-se acima do valor basal, enquanto que a pressão de platô manteve-se abaixo. Não foi observada alteração significante nas variáveis hemodinâmicas. CONCLUSÃO: O suspiro em pacientes ventilados mecanicamente foi capaz de melhorar a oxigenação e a mecânica pulmonar sem comprometer a estabilidade hemodinâmica.
INTRODUCTION: The sigh is characterized by a slow and deep inhalation, followed by a slow exhalation. Studies suggest that the addition of one breath per minute in patients with acute respiratory distress syndrome, ventilated on PSV, improves oxygenation and pulmonary mechanics. OBJECTIVE: Analyze the impact of the alveolar recruitment maneuver through breath in pulmonary mechanics and oxygenation in mechanically ventilated patients, in addition to checking the hemodynamic impact and the incidence of complications associated with the use of the technique. MATERIALS AND METHODS: Experimental study with 17 patients on mechanical ventilation, showing a relationship between partial pressure of alveolar oxygen and fraction of inspired oxygen (PaO2/FiO2) below 300mmHg. Respiratory, pulmonary mechanics, and hemodynamic data were evaluated. Data were collected during three periods: before sigh, immediately after, and 15 minutes after the technique. Two sighs per minute were administered using airways pressure limited to 40 cmH2O, during an inspiratory time of four seconds. RESULTS: After the sigh, there was an increase in PaO2, resistive pressure, static compliance, and PaO2/FiO2 ratio, in addition to a decrease in plateau pressure and partial pressure of alveolar carbon dioxide (PaCO2). After 15 minutes of sigh removal, it was observed that PaO2, resistive pressure, static compliance, and PaO2/ FiO2 ratio remained above the baseline, while the plateau pressure remained below. There was no significant change in hemodynamic variables. CONCLUSION: The sigh in mechanically ventilated patients was able to improve oxygenation and pulmonary mechanics without compromising hemodynamic stability

RESUMEN Un nuevo coronavirus, denominado COVID-19, fue descubierto por el brote iniciado en China a finales de diciembre del año 2019. Los síntomas característicos son fiebre, tos seca, dificultad respiratoria y malestar general. Muchas investigaciones se están llevando a cabo ya que, si bien no es una enfermedad considerada mortal, tiene un índice de contagio muy alto. Sin embargo, junto a los cuidados hospitalarios y extrahospitalarios, existe un grupo de fármacos que se vienen utilizando para combatir esta enfermedad, tales como hidroxicloroquina, cloroquina, remdesivir, lopinavir/ritonavir, tocilizumab, interferón beta 1B, entre otros.
ABSTRACT A novel coronavirus disease called COVID-19 was discovered as a result of the outbreak that began in China at the end of December 2019. Common symptoms are fever, dry cough, shortness of breath and malaise. Several research are being conducted since the disease has high transmission rate even though it is not considered life-threatening. However, together with hospital and out-of-hospital care, there is a group of medications being used to fight this disease, such as hydroxychloroquine, chloroquine, remdesivir, lopinavir/ritonavir, tocilizumab, interferon beta-1b, among others.
ABSTRACT
Objective:To explore the clinical characteristics and predictors of severe acute pancreatitis complicated with acute respiratory distress syndrome (SAP-ARDS).Methods:Clinical data of consecutive 313 SAP patients hospitalized from January 2000 to January 2020 in Peking Union Medical College Hospital, were retrospectively analyzed, including 258 cases with ARDS (ARDS group) and 55 cases without ARDS (non-ARDS group). According to the severity of ARDS, ARDS group were further divided into mild ARDS group (165 cases) and moderate to severe ARDS group (93 cases). Clinical symptoms, laboratory examination and imaging results, ICU admission time and clinical outcome, as well as the local and systemic complications, acute physiology and chronic health evaluation (APACHEⅡ) within 24 h after admission, bedside index for severity in acute pancreatitis (BISAP), CT severity index (CTSI), sequential organ failure assessment (SOFA) and quick sequenctial organ failure assessment(qSOFA) score were recorded. Univariate and multivariate logistic regression were performed to analyze independent risk factors of SAP complicated with moderate to severe ARDS. Receiver operating characteristics curves (ROC) was drawn to calculate area under the ROC curve (area under curve, AUC) and evaluate the performance of WBC and hsCRP in predicting SAP complicated with moderate to severe ARDS, and assess the performance of APACHEⅡ, BISAP, CTSI, SOFA and qSOFA scores in predicting SAP-ARDS endotracheal intubation.Results:The ICU length of stay and mortality rate of SAP-ARDS patients were significantly higher than those without ARDS [(8.3±11.6 day vs 5.7±7.7 day, 12.4% vs 3.6%, all P value <0.05)]. Univariate analysis showed that elevated WBC ( OR 4.52, 95% CI 1.64-12.4) and hsCRP ( OR 3.69, 95% CI 1.29-10.48) on admission were independent risk factors for moderate to severe ARDS with SAP. The AUC of WBC and hsCRP for predicting SAP with moderate to severe ARDS at admission were 0.651(95% CI 0.532-0.770) and 0.615 (95% CI 0.500-0.730), respectively. The predicted cut-off values (Cut-off values) were 17.5×10 9/L and 159 mg/L, respectively, and the sensitivity was 53.1% and 78.1%, the specificity was 78.1% and 48.4% respectively. The area under the ROC curve for APACHEⅡ, BISAP, CTSI, SOFA, and qSOFA score 24 h after admission in the early prediction of endotracheal intubation were 0.739 (95% CI 0.626-0.840), 0.705 (95% CI 0.602-0.809), 0.753 (95% CI 0.650-0.849 ), 0.737 (95% CI 0.615-0.836) and 0.663 (95% CI 0.570-0.794), and the optimum Cut-off values were 14 points, 3 points, 5 points, 7 points, 2 points, and the sensitivity and specificity for these predictors were 58.8% and 81.4%, 79.4% and 60.0%, 73.5% and 67.1%, 38.2% and 98.6%, 45.5% and 83.3%, respectively. Conclusions::Elevated blood WBC and hsCRP on admission were independent risk factors for moderate to severe ARDS in SAP. APACHEⅡ≥14, BISAP≥3, CTSI≥5, SOFA≥7, or qSOFA≥2 within the 24 h admission indictaed that the risk of SAP patients to receive endotracheal intubation was high.
ABSTRACT
Objective:To investigate the expression and significance of granulocyte colony-stimulating factor (G-CSF) and granulocyte-macrophage colony-stimulating factor (GM-CSF) in patients with acute respiratory distress syndrome (ARDS).Methods:The clinical data of 81 patients with ARDS who received treatment between February 2018 and July 2020 in Linhai Second People's Hospital, China (group A) and 69 healthy controls who concurrently received physical examination (group B) were retrospectively analyzed. Serum levels of G-CSF, GM-CSF and oxygenation index (OI) measured before treatment in the group A were compared with the levels measured in the control group. Serum levels of G-CSF and GM-CSF measured before treatment were compared between patients with different disease severities in the group A. The correlation between serum G-CSF and GM-CSF levels and disease condition was analyzed. The significance of serum G-CSF and GM-CSF levels in the diagnosis of ARDS was investigated.Results:Before treatment, serum G-CSF and GM-CSF levels in the group A were (201.89 ± 19.44) ng/L, (48.95 ± 6.03) ng/L, respectively, which were significantly higher than those in the group B [(38.13 ± 5.22) ng/L, (7.71 ± 0.92) ng/L, t = 67.889, 56.228, both P < 0.001]. OI in the group A was significantly lower than that in the group B [(159.09 ± 16.81) mmHg vs. (385.13 ± 20.34) mmHg, t = 74.519, P < 0.001). In group A, serum levels of G-CSF and GM-CSF were (271.99 ± 23.15) ng/L and (65.07 ± 8.38) ng/L respectively in patients with severe acute respiratory distress syndrome ( n = 13), (203.14 ± 18.36) ng/L and (50.91 ± 7.18) ng/L respectively in patients with moderate acute respiratory distress syndrome ( n = 30), and (176.92 ± 15.98) ng/L and (41.89 ± 6.02) ng/L, respectively in patients with mild acute respiratory distress syndrome ( n = 38). There was significant difference among patients with severe, moderate and mild acute respiratory distress syndrome ( F = 133.201, 57.116, both P < 0.05). Serum levels of G-CSF and GM-CSF in group A were negatively correlated with OI ( r = -0.819, -0.824, both P < 0.05). The area under the receiver operating characteristic curve of serum levels of G-CSF and GM-CSF and their combination were 0.780 (95% CI: 0.628-0.933), 0.752 (95% CI: 0.590-0.913) and 0.912 (95% CI: 0.835-0.989), respectively. The Youden index was 0.686, 0.696 and 0.739, respectively. The area under the receiver operating characteristic curve and the Youden index of the combined detection of serum levels of G-CSF and GM-CSF were highest. Conclusion:Serum levels of G-CSF and GM-CSF in patients with ARDS were higher than those in healthy controls. Higher serum levels of G-CSF and GM-CSF led to more severe disease condition. Serum levels of G-CSF and GM-CSF in combination has a higher value in the diagnosis of ARDS than serum levels of G-CSF and GM-CSF alone.
ABSTRACT
Objective:To analyze the influencing factors of death in patients with acute respiratory distress syndrome (ARDS) combined with acute kidney injury (AKI) in intensive care unit (ICU) after continuous renal replacement therapy (CRRT).Methods:The demographic and clinical data of ICU patients with ARDS combined with AKI after CRRT at Henan Provincial People's Hospital from January 1, 2018 to December 31, 2018 were collected. According to the final treatment results of this hospitalization, the patients were divided into death group and survival group. Survival was defined as the improved patient's condition and hospital discharge. Death was defined as the patient's death during the ICU hospitalization or confirmed death after abandoning treatment and automatically being discharged from the hospital in the follow-up. The basic clinical characteristics and CRRT status between the two groups were compared. Multivariate logistic regression method was used to analyze the influencing factors of death in patients.Results:A total of 132 patients were enrolled, of which 90 patients (68.2%) died, with 84 males (63.6%) and median age of 59(45, 73) years. Compared with the survival group, the death group had higher age, proportion of malignant tumors, sequential organ failure assessment (SOFA) score, number of organ dysfunction and proportion of positive balance of fluid accumulation at 72 hours, longer time from entering ICU to CRRT, and lower mean arterial pressure (minimum value) and oxygenation index (all P<0.05). Multivariate logistic regression analysis results showed that the age≥60 years old ( OR=4.382, 95% CI 1.543-12.440, P=0.006), large number of organ dysfunction ( OR=1.863, 95% CI 1.109-3.130, P=0.019), high SOFA score ( OR=1.231, 95% CI 1.067-1.420, P=0.004) and long time from ICU admission to CRRT ( OR=1.224, 95% CI 1.033~1.451, P=0.020) were independent influencing factors of death in patients with ARDS combined with AKI after CRRT, and high oxygenation index ( OR=0.992, 95% CI 0.986-0.998, P=0.010) was an independent protective factor for patients' prognosis. Conclusions:The mortality of patients with ARDS combined with AKI after CRRT is still high. The age≥60 years old, large number of organ dysfunction, high SOFA score and long time from ICU admission to CRRT are independent influencing factors for death, and high oxygenation index is an independent protective factor for prognosis in patients with ARDS combined with AKI after CRRT.
ABSTRACT
Acute respiratory distress syndrome (ARDS) is a common complication of severe acute pancreatitis (SAP) and a leading cause of early death in SAP patients, but its pathogenesis is still unclear. In recent years, the role of gut microbiota and its metabolites in regulating SAP-related ARDS has attracted more and more attention, and in-depth studies on the pathogenesis of “intestine-lung axis” may provide new ideas for the research and development of drugs for SAP-related ARDS. This article summarizes the recent research advances in gut microbiota and its metabolites in SAP-related ARDS.
