Seguimiento Funcional hasta Seis Meses después de Sobrevivir a Cuidados Intensivos: Lecciones aprendidas de un Estudio Chileno Multicéntrico / Functional follow-up six months after surviving intensive care: lessons learned from a Chilean multicenter study

Introducción. Las tasas de retención en los estudios de seguimiento oscilan entre el 32 y 100%, demostrando el desafío que implica realizar estudios longitudinales de sobrevivientes de la unidad de cuidados intensivos (UCI). Objetivo. Identificar las estrategias implementadas y lecciones aprendidas en un estudio prospectivo multicéntrico de seguimiento de sobrevivientes de la UCI durante la pandemia. Métodos. Estudio post-hoc de las lecciones aprendidas mediante encuestas y entrevistas dirigidas a explorar la experiencia de los investigadores y coordinadores del estudio IMPACCT COVID-19, realizado en siete centros chilenos entre octubre 2020 y abril 2021 evaluando el síndrome post-cuidados intensivos de sobrevivientes hasta seis meses después. Resultados. Identificamos ocho lecciones: 1) selección de instrumentos de medición, 2) identificación de centros participantes, 3) aprobación del estudio, 4) financiamiento, 5) capacitación de evaluadores, 6) coordinación/aseguramiento de calidad, 7) reclutamiento y 8) seguimiento de pacientes. Incluso durante el primer año de pandemia, reclutamos 252 pacientes a una tasa de 1,4 pacientes/día con una retención del 48% a los 6 meses de seguimiento. El uso de redes académicas existentes y las estrategias de comunicación entre investigadores, coordinadores y evaluadores fueron aspectos positivos; mientras que la fidelización con evaluadores al egreso de la UCI y con pacientes durante el seguimiento son aspectos que deberían considerarse en futuros estudios. Conclusiones. Se evaluaron más de 250 pacientes en seis meses durante la pandemia, con tasas de retención post UCI acorde a la literatura. Futuros estudios debiesen optimizar los procesos de medición y de seguimiento para minimizar la pérdida de pacientes.

Background. Retention rates of follow-up studies range from 32 to 100%, demonstrating the challenge to conduct longitudinal studies of intensive care unit (ICU) survivors. Objective. To identify the strategies implemented and lessons learned in a multicenter prospective follow-up study of ICU survivors during pandemic times. Methods. Post-hoc study of lessons learned through surveys and interviews aimed at exploring the experience of the researchers and coordinators of the IMPACCT COVID-19 study. The original study was performed in seven Chilean sites between October 2020 and April 2021 evaluating the post-intensive care syndrome of survivors up to six-month follow-up. Results. We identified eight lessons: 1) selection of measurement instruments, 2) identification of participating sites, 3) Study approval, 4) funding, 5) evaluators training, 6) coordination/quality assurance, 7) recruitment, and 8) patient follow-up. Even during the first year of the pandemic, we recruited 252 patients at a rate of 1.4 patients/day with a retention rate of 48% at 6 months of follow-up. The use of existing academic networks and communication strategies between researchers, coordinators and evaluators were positive aspects; while evaluators fidelity at ICU discharge and patient engagement during follow-up are aspects should be considered. Conclusions. More than 250 patients were evaluated in six months during the pandemic, with post-ICU retention rates consistent with the literature. Future studies should optimize measurement and monitoring processes to minimize patient atrition.

Terapia medico nutricional en pacientes que reciben terapia de oxigenación por membrana extracorpórea: conocimiento en progreso / Medical nutrition therapy in patients receiving extracorporeal membrane oxygenation: knowledge in progress

Resumen El soporte nutricional (SN) en pacientes adultos que reciben terapia de oxigenación por membrana extracorpórea (ECMO, extracorporeal membrane oxygenation) es controvertido. Si bien existen guías para el SN en pacientes pediátricos con ECMO, en adultos no se cuenta con estos lineamientos para el uso, tipo, ruta y momento de la terapia nutricional. En pacientes críticamente enfermos es bien sabido que la nutrición enteral (NE) temprana es beneficiosa, no obstante existe la posibilidad de que en pacientes con ECMO la NE temprana condicione complicaciones gastrointestinales. Asimismo, no se han establecido metas calóricas, proteicas y dosis o tipos de micronutrimentos que usar para esta población en específico, siendo un reto para el clínico encargado de brindar el SN. Aunado a esto los pacientes con ECMO son algunos de los más gravemente enfermos en las unidades de cuidados intensivos, donde la desnutrición se asocia con una mayor morbilidad y mortalidad. En cuanto al uso de nutrición parenteral (NP), no se tiene descrito si implica riesgo de falla en el circuito al momento de introducir lípidos al oxigenador. Por lo anterior es imperativa una correcta evaluación e intervención nutricional específica, realizada por expertos en el tema para mejorar el pronóstico y la calidad de vida en esta población, siendo un objetivo primordial en los cuidados de los pacientes adultos que reciben terapia de ECMO.

Abstract Nutritional support in adult patients receiving extracorporeal membrane oxygenation (ECMO) therapy is controversial. Although there are guidelines for the NS (Nutritional support) in pediatric patients with ECMO, in adults these guidelines are not available for the use, type, route and timing of nutritional therapy. In critically ill patients it is well known that early enteral nutrition is beneficial, however there is the possibility that in patients with ECMO early enteral nutrition leads to gastrointestinal complications. Likewise, there have not been established caloric targets, proteins and doses or types of micronutrients to use for this specific population being a challenge for the clinician. In addition, patients with ECMO are some of the most seriously ill in intensive care units, where malnutrition is associated with increased morbidity and mortality. Regarding the use of parenteral nutrition (NP) it has not been described if it implies a risk of circuit failure at the time of introducing lipids to the oxygenator. Therefore, a correct evaluation and specific nutritional intervention by experts in the field is imperative to improve the prognosis and quality of life in this population, which is a primary goal in the care of adult patients receiving extracorporeal membrane oxygen.

Fluid overload: clinical outcomes in pediatric intensive care unit

Abstract Objective The aim of this study was to analyze the effects of fluid overload related to mechanical ventilation, renal replacement therapy, and evolution to discharge or death in critically ill children. Methods A retrospective study in a Pediatric Intensive Care Unit for two years. Patients who required invasive ventilatory support and vasopressor and/or inotropic medications were considered critically ill. Results 70 patients were included. The mean age was 6.8 ± 6 years. There was a tolerable increase in fluid overload during hospitalization, with a median of 2.45% on the first day, 5.10% on the third day, and 8.39% on the tenth day. The median fluid overload on the third day among those patients in pressure support ventilation mode was 4.80% while the median of those who remained on controlled ventilation was 8.45% (p = 0.039). Statistical significance was observed in the correlations between fluid overload measurements on the first, third, and tenth days of hospitalization and the beginning of renal replacement therapy (p = 0.049) and between renal replacement therapy and death (p = 0.01). The median fluid overload was 7.50% in patients who died versus 4.90% in those who did not die on the third day of hospitalization (p = 0.064). There was no statistically significant association between death and the variables sex or age. Conclusions The fluid overload on the third day of hospitalization proved to be a determinant for the clinical outcomes of weaning from mechanical ventilation, initiation of renal replacement therapy, discharge from the intensive care unit, or death among these children.

CORRELATION OF SERUM FERRITIN AND LDH ON CRITICALLY ILL PATIENTS OF COVID-19 DISEASE DURING 1ST AND 2ND WAVE OF COVID 19 PANDEMIC IN TERTIARY CARE HOSPITAL, INDIA

In both the earlier waves of COVID-19 variants, severe and fatal respiratory disease like acute respiratory distress syndrome (ARDS) became more fatal in population with comorbid conditions. Therefore, early identi?cation of severe COVID-19 is very important for individual's precise management, including antiviral, oxygen support and intensive care unit (ICU) management. First case of COVID-19 got reported in the medical record of India on 30th January 2020 in a student who had returned from Wuhan, China. In 2020 and 2021 it was found that individuals with increased serum ferritin and LDH level landed up with severe and very severe COVID-19 if not treated timely and correctly. So correlation between S. Ferritin and LDH in 1st and 2nd wave was required to evaluate the condition of patients who remained admitted in critical care unit with or without comorbid conditions. This is hospital based cross- sectional observational study on 50-50 (total-100) critically ill patients admitted during 2020 and 2021 respectively. We found that In 2020 during the 1st wave serum LDH and serum Ferritin levels were signi?cantly high with the mean value of 481.65 U/L and 532.56 ng/ml respectively and in 2021 during 2nd wave serum LDH and serum Ferritin levels were again signi?cantly high with the mean value of 488.43 U/L and 667.27 ng/ml respectively. In 2020 patients with comorbid conditions showed S. LDH and Ferritin mean value of 543.47 U/L and 582.63 ng/ml respectively and in 2021 during 2nd wave it showed S.LDH and Ferritin levels mean value of 672.72 U/L and 727.38 ng/ml respectively. Both in?ammatory markers were signi?cantly more increased in the critically ill patients who presented with co-morbidities. This study will provide improved con?dence to health workers working in remote areas and COVID-19 hospitals in predicting transfer of COVID-19 patients to tertiary care hospitals for critical care management at the earliest.

Summary of the best evidence for the energy and protein intake targets and calculation in critically ill patients / 中华危重病急救医学

Objective:To evaluate and summarize the best evidence of energy and protein intake targets and calculation in adult critically ill patients, and to provide evidence-based basis for critical nutrition management.Methods:Evidence related to energy and protein intake targets and calculation of adult critically ill patients, including guideline, expert consensus, systematic review and evidence summary, were systematically searched in PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Embase, Cochrane Library, UpToDate, BMJ Best Practice, Joanna Briggs Institute (JBI), Web of Science, SinoMed, Medive, China National Knowledge Infrastructure, Wanfang database, VIP database, Guidelines International Network (GIN), National Institute for Health and Care Excellence (NICE), National Guideline Clearinghouse (NGC), Registered Nurses Association of Ontario (RNAO), and Society of Critical Care Medicine (SCCM) from January 2012 to June 2022. Two researchers independently evaluated the quality of the included literatures using the JBI Evidence-based Health Care Center evaluation tool and the Appraisal of Clinical Practice Guidelines for Research and Evaluation Ⅱ (AGREE Ⅱ), extracted and summarized the best evidence for the nutritional intake goal and calculation of adult critically ill patients, and described the evidence.Results:A total of 18 literatures were included, including 5 clinical guidelines, 8 expert consensus, 3 systematic reviews and 2 evidence summaries. After literature quality evaluation, 18 articles were all enrolled. The evidence was summarized from the four aspects, including energy target calculation method, dose body weight, energy and protein intake target, and calculation method, 24 pieces of the best evidence were finally formed.Conclusions:The best evidence of energy and protein intake targets and calculation for critically ill patients was summarized based on evidence-based. Clinical medical staff can choose indirect calorimetry to calculate energy goals when equipment is available. Patient's height, body weight should be recorded accurately, dose body weight can be determined by body mass index (BMI). Meanwhile, blood urea nitrogen (BUN) loss, fat-free body weight, simple formulas and other methods should be used to continuously evaluate and adjust protein intake targets, to achieve the purpose of optimizing intensive nutrition support.

Effects of individualized dosing regimen on blood trough concentration of vancomycin and renal function in critically ill patients / 中国药房

OBJECTIVE To investigate the effects of individualized dosing regimen on blood trough concentration of vancomycin and renal function in critically ill patients. METHODS According to relevant guidelines and the results of Vancomycin Calculator， clinical pharmacists formulated an individualized dosing regimen of vancomycin including loading dose and maintenance dose for critically ill patients based on the two independent variables of body weight and creatinine clearance rate. Using the method of retrospective study， patients who were admitted to the department of intensive care unit （ICU） of the Second Affiliated Hospital of Guangzhou Medical University and used the regimen from July 2018 to December 2021 were selected as the trial group， and patients who were treated with vancomycin and received blood drug concentration monitoring in ICU from January 2015 to June 2018 were recruited in the control group. The difference in trough concentration distribution and the incidence of acute kidney injury （AKI） after medication were compared between the two groups， the change of serum creatinine before and after medication in the trial group was analyzed. RESULTS Totally 197 patients were included in the trial group and 144 patients were in the control group. There was no significant difference between the two groups in the clinical information （gender， age， body weight， acute physiology and chronic health evaluation Ⅱ score， the proportion of patients with renal insufficiency， etc.） （P＞0.05）. The proportions of major infection sites （including lung， urinary， abdominal， blood and central nervous system） and treatment type （target or empirical treatment） also had no significant difference between the two groups （P＞0.05）. There was no significant difference in the attainment rate of ideal trough concentration （15-20 μg/mL） and the proportion of patients with trough concentration　＞20 μg/mL between the two groups （P＞0.05）， while the attainment rate of target trough concentration （10-20 μg/mL） and the proportion of patients with trough concentration ＜10 μg/mL were significantly different between the two groups （P＜0.05）. The attainment rate of target trough concentration in patients with chronic renal insufficiency in trial group was significantly higher than that in control group （P＜0.05）. There was no significant difference in the incidence of AKI and vancomycin-associated AKI between the two groups （P＞0.05）. In the trial group with medication duration ≥7 days ， the level of serum creatinine on the 7th day of treatment was increased significantly， compared with that on the 3rd day of treatment （P＜0.05）. CONCLUSIONS This individualized dosing regimen can improve the attainment rate of target trough concentration of vancomycin in critically ill patients， especially those with chronic renal insufficiency， during the first standardized monitoring， and not increase the risk of renal injury compared with previous empirical medication.

Research progress on feeding intolerance and the relationship between feeding intolerance and ultrasonic monitoring of gastric residual volume / 中国小儿急救医学

Feeding intolerance is a common cause of enteral nutrition interruption, which has a high incidence in the pediatric intensive care unit.It seriously affects the nutritional management of critically ill children, affects the treatment effect of critically ill children, and can lead to serious complications and even death.There is a lack of standardized and unified standards for the assessment of feeding intolerance in clinical practice, and there is an urgent need for objective and standard assessment tools.Ultrasound is a non-invasive, simple and non-radiation clinical technique, which can be used to measure gastric residual volume at the bedside in critically ill children, and evaluate feeding intolerance.

Blood glucose management in critically ill children / 中国小儿急救医学

Hyperglycemia, hypoglycemia, and even glucose metabolism crisis and cerebral edema are common complications in critically ill children with glucose metabolism disorders.In clinical practice, blood glucose monitoring should be strengthened.When glucose is abnormal, it should be treated in time to control it within the normal range and reduce complications.This review elucidated and discussed the diagnosis of hyperglycemia and hypoglycemia, blood glucose monitoring, glycemic target and treatment scheme for abnormal glucose metabolism in critically ill children to provide suggestions for blood glucose management in pediatric intensive care unit.

Based on the theory of treating impotence alone with Yang Ming to explore the intervention of finger-pressing therapy on ICU-acquired weakness in critically ill children / 中国实用护理杂志

Objective:To explore the clinical feasibility of finger-pressing therapy based on the theory of treating impotence alone with Yang Ming to reduce incidence of ICU acquired weakness (ICU-AW) in critically ill children and provide a feasible nursing plan for ICU acquired asthenia in critically ill children.Methods:A quasi-experimental study was conducted. A total of 73 critically ill children were admitted to the PICU of Kunming Children′s Hospital from January 1 to April 30, 2021. According to the random number table, the subjects were divided into the observation group (37 cases) and the control group (36 cases). Children in the control group received routine PICU nursing. The children in the observation group were treated with PICU routine nursing and finger-pressing therapy based on the theory of treating impotence alone with Yang Ming. The two groups were compared in terms of limb muscle strength score (MRC-Score), incidence of ICU-AW, basic activities of life (Barthel Index, BI), limb muscle thickness.Results:After intervention, the MRC-Score of the observation group was 50 (46, 52) points, which was higher than 46 (40, 48) points of the control group, and the difference between the two groups was statistically significant ( Z=-3.70, P<0.05). The incidence of ICU-AW in the observation group was 32.43% (12/37), and the incidence of ICU-AW in the control group was 72.22% (26/36). The difference between the two groups was statistically significant ( χ2=11.58, P<0.05). The BI score of the observation group was 63 (50, 70), which was higher than 44 (40,60) of the control group, and the difference between the two groups was statistically significant ( Z=-3.94, P<0.05). The reduction degree of quadriceps femoris thickness in the observation group at D3-D1 was (-0.381 ± 0.131) cm, which was lower than (-0.762 ± 0.182) cm in the control group, and the difference between the two groups was statistically significant ( t=10.29, P<0.05). Conclusions:The application of finger-pressing therapy guided by theory of treating impotence alone with Yang Ming in the early rehabilitation of critically ill children can enhance muscle strength, prevent muscle atrophy and reduce the incidence of ICU-AW in critically ill children.

Patient care during interfacility transport:a narrative review of managing diverse disease states / 世界急诊医学杂志（英文）

BACKGROUND:When critically ill patients require specialized treatment that exceeds the capability of the index hospitals,patients are frequently transferred to a tertiary or quaternary hospital for a higher level of care.Therefore,appropriate and effi cient care for patients during the process of transport between two hospitals(interfacility transfer)is an essential part of patient care.While medical adverse events may occur during the interfacility transfer process,there have not been evidence-based guidelines regarding the equipment or the practice for patient care during transport.METHODS:We conducted searches from the PubMed,Cumulative Index of Nursing and Allied Health(CINAHL),and Scopus databases up to June 2022.Two reviewers independently screened the titles and abstracts for eligibility.Studies that were not in the English language and did not involve critically ill patients were excluded.RESULTS:The search identified 75 articles,and we included 48 studies for our narrative review.Most studies were observational studies.CONCLUSION:The review provided the current evidence-based management of diverse disease states during the interfacility transfer process,such as proning positioning for respiratory failure,extracorporeal membrane oxygenation(ECMO),obstetric emergencies,and hypertensive emergencies(aortic dissection and spontaneous intracranial hemorrhage).

Analysis of risk factors for delirium in critically ill patients in a psychiatric hospital： a retrospective study / 四川精神卫生

BackgroundThe incidence of delirium in critically ill psychiatric patients is high， and there are many factors affecting delirium occurrence. At present， epidemiological studies on delirium among critically ill patients in psychiatric hospitals are limited. ObjectiveTo explore the risk factors for delirium in critically ill patients in a psychiatric hospital， so as to guide the clinical management of delirium in psychiatric hospitals. MethodsThis retrospective study included 427 critically ill patients who were admitted to Shenzhen Kangning Hospital from January 1， 2019 to May 31， 2021. The delirium situation， gender， age， pre-admission course of illness （duration from the onset of acute mental state changes to in-patient registration at a psychiatric hospital）， history of mental illness， history of cognitive dysfunction， history of using psychoactive substances， history of using sedative and hypnotic drugs， number of combined chronic diseases， number of combined drugs and type of disease were examined as potential risk factors for delirium. Single Logistic regression was used to analyze the potential risk factors for delirium， and the potential risk factors were incorporated into the multi-factor Logistic regression analysis model so as to gradually screen out the risk factors for delirium in critically ill psychiatric patients. ResultsDelirium was present in 33.49% （143/427） of critically ill patients. Multi-factor Logistic regression analysis demonstrated that the presence of delirium was associated with mental and behavioral disorders caused by psychoactive substances （OR=8.949， P<0.01）， absent history of mental illness （OR=4.202， P<0.01）， number of combined chronic diseases （OR=1.249， P<0.01）， age （OR=1.031， P<0.01） and pre-admission course of illness （OR=0.942， P<0.01） . ConclusionDelirium was present in nearly 1/3 critically ill patients in the psychiatric hospital. The risk factors for delirium included short course of illness before admission， age， more combined chronic diseases， absent history of mental illness， mental and behavioral disorders caused by psychoactive substances. ［Funded by Shenzhen Fund for Guangdong Provincial High-level Clinical Key Specialties （number， SZGSP013）］

Application of transport ventilator in the inter-hospital transport of critically ill children / 中国当代儿科杂志

OBJECTIVES@#To study the application value of transport ventilator in the inter-hospital transport of critically ill children.@*METHODS@#The critically ill children in Hunan Children's Hospital who were transported with or without a transport ventilator were included as the observation group (from January 2019 to January 2020; n=122) and the control group (from January 2018 to January 2019; n=120), respectively. The two groups were compared in terms of general data, the changes in heart rate, respiratory rate, and blood oxygen saturation during transport, the incidence rates of adverse events, and outcomes.@*RESULTS@#There were no significant differences between the two groups in sex, age, oxygenation index, pediatric critical illness score, course of disease, primary disease, heart rate, respiratory rate, and transcutaneous oxygen saturation before transport (P>0.05). During transport, there were no significant differences between the two groups in the changes in heart rate, respiratory rate, and transcutaneous oxygen saturation (P>0.05). The incidence rates of tracheal catheter detachment, indwelling needle detachment, and sudden cardiac arrest in the observation group were lower than those in the control group during transport, but the difference was not statistically significant (P>0.05). Compared with the control group, the observation group had significantly shorter duration of mechanical ventilation and length of stay in the pediatric intensive care unit and significantly higher transport success rate and cure/improvement rate (P<0.05).@*CONCLUSIONS@#The application of transport ventilator in the inter-hospital transport can improve the success rate of inter-hospital transport and the prognosis in critically ill children, and therefore, it holds promise for clinical application in the inter-hospital transport of critically ill children.

“Cold-dampness entering ying （营）” is the key to the worsening of cold-dampness epidemic， and is more common in the elderly or critically ill cases of cold-dampness epidemic with pathogen exuberance and healthy qi deficiency. This paper reported a case of critically ill COVID-19 combined with multiple organ dysfunction treated by integrative traditional Chinese and western medicine based on “cold-dampness entering ying” theory. The patient did not have high fever after being infected with SARS-Cov-2， but D-dimer continued to increase， and she developed multiple thrombosis throughout the body and multiple organ dysfunctions such as pulmonary embolism， edema， oliguria， and shock. The patient were with enlarged and dusky tongue， with yellow， thick and greasy coating， and sublingual blood stasis， and thready， rapid and rough pulse. All these were characteristic manifestations of “cold-dampness entering ying”， and was differentiated as cold-dampness stasis. For the treatment， symptomatic and supportive western medicine of improving heart function， anti-infection， relieving asthma， stopping cough and reducing phlegm was given as the basic therapy， and additionally， traditional Chinese medicine to open the constraint and the blocked， save from collapse and restore yang， boost qi and relieve collapse， invigorate blood and drain water was used， usually with Modified Poge Zilong Xuanbai Chengqi Decoction （破格子龙宣白承气汤加减）， which was in accordance with the pathogenesis and thus achieving good effect.

Development of a risk prediction score for acute kidney injury in critically-ill septic Filipino patients admitted in perpetual succour hospital

Introduction@#Acute kidney injury (AKI) is a lethal complication of critical illness characterized by the rapid loss of the kidney's excretory function encountered in 50% of intensive care unit (ICU) admissions. Its impact on the outcome of critically ill patients makes AKI a significant cause of morbidity and mortality.@*Objectives@#To develop and validate an acute kidney injury risk prediction score based on routinely available variables and common laboratories of admitted critically-ill septic Filipino patients.@*Methods@#This is a prospective cohort study conducted in a tertiary hospital in Cebu from February to September 2020. The data of 2545 patients were identified by chart review but only 607 patients with a quick Sepsis Organ Failure Assessment Score (qSOFA) score of >2 were included in the pre-screening. After stratified sampling, a total of 198 septic ICU patients were enrolled. Demographic profile, laboratory results and outcome data were collated. Variables were screened then stepwise forward elimination was done to identify the significant predictors. An AKI risk score model was developed with binomial regression analysis by identifying independent prognostic factors. The diagnostic ability of the model was determined by the Area under the Receiver Operating Characteristics (AuROC).@*Results@#AKI developed in 155 (78%) patients. The significant predictors for Acute Kidney Injury were age, hypertension, atherosclerotic cardiovascular disease, weight, white blood count, creatinine, and BUN. An AKI prediction model with a cut off score of 161.9 was made with a fair diagnostic ability for predicting AKI at 0.79 based on AuROC.@*Conclusion@#The developed risk prediction tool using routinely available variables is found to be fairly accurate to predict the development of AKI among critically ill septic patients.

The risk factors of postoperative atrial fibrillation in critically ill lung surgery patients and the establishment of nomogram / 中华胸心血管外科杂志

Objective:To identify the risk factors of postoperative atrial fibrillation (POAF) in critically ill lung surgery patients and establish a nomogram.Methods:213 critically ill lung surgery patients were collected in Beijing Chaoyang Hospital from January 2018 to December 2021. Logistic analysis was used to analyze the risk factors of POAF. A nomogram was developed based on the verified risk factors. Results:The independent risk factors associated with POAF was mitral regurgitation ( OR=4.270, 95% CI: 1.380-13.213, P=0.012), cedilanid ( OR=14.619, 95% CI: 2.913-73.373, P=0.001), catecholamine ( OR=3.244, 95% CI: 1.144-9.203, P=0.027), pericardiotomy( OR=6.079, 95% CI: 1.362-27.128, P=0.009), systematic lymph node dissection( OR=5.460, 95% CI: 1.770-16.846, P=0.003). Nomogram model showed the ROC was 0.801(95% CI: 0.721-0.881, P<0.001). Conclusion:The risk factors of POAF in critically ill lung surgery patients are mitral regurgitation, cedilanid, catecholamine, pericardiotomy and systematic lymph node dissection. The nomogram predicted POAF better than other scoring systems.

Comparing the Prognosticative Value of APACHE II and mSOFA Scores in Critically Ill Patients: A Prospective Study

Objective: Several predictive scoring systems measuring disease severity are used to predict outcomes, typically mortality, of critically ill patients in the intensive care unit (ICU). Two common validated predictive scoring systems include acute physiology and chronic health evaluation II (APACHE II) and modified sequential organ failure assessment score (mSOFA). To compare performance of APACHE II and mSOFA score in critically ill patients regarding the outcomes in the form of morbidity and mortality in ICU. Methods: This prospective observational clinical study was conducted on 100 patients over 6 months. For each patient, APACHE II score on day of admission and serial mSOFA scores on day 0, 3, 7 and 10 were calculated and compared. Results: The age of the non-survivors was significantly older than survivors was (57.1±11.76 and 54.28±15.16). [In our study we found that the mean length of ICU stay of non-survivors was (5.41±4.81) & survivors(8.63± 4.81) days.] In our study mortality rate was 40%.The APACHE II score with cut-off point of 23 demonstrated a sensitivity rate of 98.33% & specificity rate of 17.5%, accuracy of 66.00%. Serial mSOFA scores with cut-off of 11 on day0, day3, day7 better differentiated survivors from non-survivors with 98.3% sensitivity, 27.5% specificity and 70% accuracy. Conclusion: Both APACHE II and mSOFA scores can help ICU physicians as a significant predictive marker for mortality in critically ill patients. The serial measurement of mSOFA score in the first week is a better mortality predictor tool than APACHE II score in critically ill patients.

Characteristics and predictors of outcomes of critically Ill children with SARS-CoV-2 infection - the PICU experience

Abstract Objective To describe the clinical characteristics, laboratory parameters, treatment, and predictors of an unfavorable outcome of critically ill children with SARS-CoV-2 infection. Method This was a prospective observational study performed in a pediatric intensive care unit (PICU) of a tertiary care COVID referral hospital among critically ill children in the age group 1 month - 12 years admitted due to SARS-CoV-2 infection from June to December 2020. Demographic, clinical profile, pSOFA and PRISM III scores, laboratory parameters, treatment, and outcomes of the patients were recorded. Children who had a prolonged PICU stay (>14 days) or died were compared with those who were discharged from PICU within 14 days to assess predictors of unfavorable outcomes. Results PICU admission rate among hospitalized SARS-CoV-2 infected children was 22.1% (92/416). Infants comprised the majority of the ICU population. Invasive mechanical ventilation and inotropic support were required for 28.3% and 37% of patients, respectively. Remdesivir, IVIg, and steroids were administered to 15.2%, 26.1%, and 54.3% of the subjects, respectively. The mortality rate was 7.6 %. MIS-C patients were older, less comorbid, and required less ventilator support but more inotrope support than acute severe COVID-19 patients. Predictors of unfavorable outcomes were age < 1 year, fever duration > 5 days, respiratory distress, shock, comorbidity, elevated CRP (> 50 mg/L), procalcitonin (> 6 ng/L), D-dimer (> 6 µg/L) and arterial lactate (> 2 mmol/L). Conclusion Critically ill children with unfavorable outcomes were predominantly infants, comorbid, prolonged fever, respiratory distress, shock and elevated inflammatory markers, D-dimer and lactate. These factors may be useful for watchful monitoring and early intervention.

Risk factors for acute kidney injury after liver transplantation in intensive care unit: a retrospective cohort study

ABSTRACT BACKGROUND: Acute kidney injury (AKI) is a frequent complication during the postoperative period following liver transplantation. Occurrence of AKI in intensive care unit (ICU) patients is associated with increased mortality and higher costs. OBJECTIVE: To evaluate occurrences of moderate or severe AKI among patients admitted to the ICU after liver transplantation and investigate characteristics associated with this complication. DESIGN AND SETTING: Single-center retrospective cohort study in a public hospital, Belo Horizonte, Brazil. METHODS: Forty-nine patients admitted to the ICU between January 2015 and April 2017 were included. AKI was defined from a modified Kidney Disease Improving Global Outcomes (KDIGO) score (i.e. based exclusively on serum creatinine levels). RESULTS: Eighteen patients (36.7%) developed AKI KDIGO 2 or 3; mostly KDIGO 3 (16 out of the 18 patients). Lactate level within the first six hours after ICU admission (odds ratio, OR: 1.3; 95% confidence interval, CI: 1.021-1.717; P = 0.034) and blood transfusion requirement within the first week following transplantation (OR: 8.4; 95% CI: 1.687-41.824; P = 0.009) were independently associated with development of AKI. Patients with AKI KDIGO 2 or 3 underwent more renal replacement therapy (72.2% versus 3.2%; P < 0.01), had longer hospital stay (20 days versus 15 days; P = 0.001), higher in-hospital mortality (44.4% versus 6.5%; P < 0.01) and higher mortality rate after one year (44.4% versus 9.7%; P = 0.01). CONCLUSION: Need for blood transfusion during ICU stay and hyperlactatemia within the first six postoperative hours after liver transplantation are independently associated with moderate or severe AKI. Developing AKI is apparently associated with poor outcomes.

Índices de oxigenación, índice de choque diastólico y tiempo en presión soporte como predictores de éxito en el retiro de la ventilación mecánica invasiva en paciente críticamente enfermo con COVID-19 / Oxygenation indices, diastolic shock index, and time in support pressure as predictors of success in the removal of invasive mechanical ventilation in critically ill patients with COVID-19 / Índices de oxigenação, índice de choque diastólico e tempo em pressão de suporte como preditores de sucesso na retirada de ventilação mecânica invasiva em pacientes em estado crítico com COVID-19

Resumen Introducción: El porcentaje de pacientes gravemente enfermos por COVID-19 que toleran el retiro de la ventilación mecánica es mínimo, por lo cual es fundamental determinar cuáles son los predictores de éxito en el retiro de la ventilación mecánica. Objetivos: Determinar si los índices de oxigenación, tiempo en presión soporte e índice de choque diastólico son predictores de éxito en el retiro de la ventilación mecánica en pacientes críticamente enfermos por COVID-19. Material y métodos: Estudio de cohorte prospectivo en pacientes con COVID-19 que ingresaron a la Unidad de Cuidados Intensivos y fueron sometidos a pruebas de ventilación espontánea, siendo posteriormente liberados del ventilador mecánico. Se recolectaron datos demográficos, resultados de laboratorio y parámetros ventilatorios con la finalidad de analizar y determinar predictores de éxito en el retiro de la ventilación mecánica. Resultados: Se observó una diferencia significativa entre los pacientes que toleraron y los que no toleraron el retiro de la ventilación mecánica en las siguientes variables: índice de respiración rápida superficial 47 ± 17.9 vs 90 ± 20.2 (p = 0.08), días de ventilación mecánica 5.8 vs 9.3 (p = 0.03), sesiones de prono 1.36 vs 2.33 (p = 0.058) y presión arterial diastólica 57 ± 3.6 (p = 0.027). Conclusión: En los pacientes críticamente enfermos por COVID-19 que son candidatos a retiro de la ventilación mecánica sugerimos usar como predictores de éxito: el índice de respiraciones rápidas superficiales < 64, días de ventilación mecánica < 8, presión arterial diastólica > 57 mmHg y haber tenido máximo dos sesiones de prono como predictores de éxito en el retiro de la ventilación mecánica.

Abstract Introduction: The percentage of critically ill patients due to COVID-19 who tolerate the withdrawal of mechanical ventilation is minimal. It is essential to determine which are the predictors of success in weaning. Objectives: To determine if the oxygenation indices, time in pressure support, and diastolic shock index are predictors of success in the withdrawal of mechanical ventilation in critically ill patients due to COVID-19. Material and methods: Prospective cohort study in patients with COVID-19 who were admitted to the ICU and underwent tests of spontaneous ventilation, being later released from the mechanical ventilator. Demographic data, laboratory results, ventilatory parameters were collected in order to analyze and determine predictors of success in weaning. Results: A significant difference was found between those who tolerated and those who did not tolerate the withdrawal of mechanical ventilation in the following variables: rapid shallow breathing index 47 ± 17.9 vs 90 ± 20.2 (p = 0.08), days of mechanical ventilation 5.8 vs 9.3 (p = 0.03), prone sessions 1.36 vs 2.33 (p = 0.058), diastolic blood pressure 57 ± 3.6 (p = 0.027). Conclusion: In critically ill patients due to COVID-19 who are candidates for withdrawal from mechanical ventilation, we suggest using as predictors of success: Index of rapid shallow breaths < 64, days of mechanical ventilation < 8, diastolic blood pressure > 57 mmHg and having had a maximum two prone sessions as predictors of success in the withdrawal of mechanical ventilation.

Resumo Introdução: A porcentagem de pacientes graves com COVID-19 que toleram a retirada da ventilação mecânica é mínima, por isso é essencial determinar os preditores de sucesso na retirada da ventilação mecânica. Objetivos: Determinar se os índices de oxigenação, tempo em pressão suporte, índice de choque diastólico são preditores de sucesso no desmame da ventilação mecânica em pacientes críticos com COVID-19.
