Résumé
Objective@#To compare outcomes of COVID-19 positive and COVID-19 negative patients who underwent tracheostomy for prolonged intubation in terms of weaning duration, length of ICU and hospital stay, overall and 30-day mortality, and explore risk factors for particular outcomes (mortality, 30-day mortality and weaning duration post tracheostomy). @*Methods@#Design: Retrospective Cohort Study Setting: Tertiary National University Hospital Participants: Of 122 adult patients that underwent tracheotomy between March 30, 2020 and March 30, 2021; 76 adult patients underwent tracheostomy for prolonged intubation were analyzed.@*Results@#Open tracheotomy was performed on 122 adult patients. Seventy six (62.3%) due to prolonged intubation and 46 (37.7%) for airway prophylaxis. Among the former, the mean age was 58.46±16.81 and 54 (71.05%) patients were female, 22 (28.95%) tested COVID-19 positive and 54 (71.05%) tested negative. Mean APACHE II score was 16.62±6.78. Average days of intubation prior to tracheostomy was 29.14±17.66 days. No statistically significant difference in outcomes (weaning days, length of stay, days discharge from ICU and hospital, 30-day mortality, days to death) were noted between COVID19 positive and negative patients who underwent tracheostomy for prolonged intubation. Mortality rates post tracheostomy in this institution appear to be higher than existing literature. On multiple linear regression analysis, days of intubation prior to tracheostomy was associated with increased weaning time post-tracheostomy (OR: 0.35 CI:0.18-0.51 95% p = <.001). This implies that for every additional day of intubation prior to tracheostomy, weaning days increase by 0.35 of a day. @*Conclusion@#Outcomes of COVID-19 compared to non-COVID-19 patients undergoing tracheostomy for prolonged intubation do not seem to be significantly different which is consistent with existing literature.

Objective:To analyze the risk factors of prolonged mechanical ventilation (PMV) in patients with sepsis complicated by abdominal surgery, and to evaluate the predictive value of risk factors for PMV.Methods:A retrospective case-control study was conducted. The clinical data of patients with postoperative abdominal sepsis complicated with invasive mechanical ventilation who were admitted to the intensive care unit (ICU) of the Affiliated Hospital of Guizhou Medical University from January 1, 2018 to December 31, 2020 were collected. The patients were divided into PMV group (duration of mechanical ventilation longer than 48 hours) and non-PMV group (duration of mechanical ventilation shorter than 48 hours) according to the duration of mechanical ventilation in ICU. The patient's gender, age, body mass index (BMI), underlying diseases, mean arterial pressure (MAP), complete blood count, blood biochemistry, arterial blood gas, cardiac function indicators, procalcitonin (PCT) at admission to the ICU, the acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) and the sequential organ failure assessment (SOFA) scores in the first 24 hours of admission to the ICU, and other clinical information were recorded. Univariate and multivariate Logistic regression models were used to analyze the risk factors for PMV. Receiver operator characteristic curve (ROC curve) was drawn to evaluate the predictive value of related indicators for PMV.Results:A total of 195 patients with sepsis after abdominal surgery who received invasive mechanical ventilation were enrolled, including 127 males (65.1%) and 68 females (34.9%), with the median age of 65 (21, 93) years old. There were 91 patients (46.7%) in the non-PMV group and 104 patients (53.3%) in the PMV group. Univariate analysis showed that the APACHEⅡ score, SOFA score, cardiac troponin T (cTnT), N-terminal pro-B type natriuretic peptide (NT-proBNP) in the PMV group were significantly higher than those in the non-PMV group. Oxygenation index (PaO 2/FiO 2), total protein (TP) and prealbumin (PA) in the PMV group were all lower than those in the non-PMV group when admitted to ICU. In the PMV group, serum creatinine (SCr), blood urea nitrogen (BUN), cystatin C (Cys C) were significantly increased, prothrombin time (PT) was significantly prolonged, the proportion of patients with septic shock and hypertension were significantly increased as compared with those in the non-PMV group. Multivariate analysis showed that low PaO 2/FiO 2 at ICU admission [odds ratio ( OR) = 0.995, 95% confidence interval (95% CI) was 0.992-0.999, P = 0.010], high ln PCT ( OR = 1.301, 95% CI was 1.088-1.555, P = 0.004), high ln cTnT ( OR = 1.562, 95% CI was 1.079-2.261, P = 0.018) and septic shock ( OR = 4.967, 95% CI was 2.461-10.026, P = 0.000) were the independent risk factors for PMV in patients with sepsis after abdominal surgery. ROC curve analysis showed that the PaO 2/FiO 2, ln cTnT, ln PCT and septic shock had certain predictive value for PMV, the area under the ROC curve (AUC) of the four variables were 0.607, 0.638, 0.690 and 0.711, the sensitivity was 50.0%, 62.5%, 86.5% and 74.0%, and the specificity was 71.4%, 62.6%, 48.3% and 68.1%, respectively. The AUC for the joint prediction of the four variables was 0.803, with a sensitivity of 76.0% and a specificity of 78.0%. It suggested that the multivariate joint prediction of PMV was more accurate. Conclusions:Decreased PaO 2/FiO 2, increased PCT, increased cTnT and the occurrence of septic shock are independent risk factors for PMV in patients with sepsis complicated by abdominal surgery. The combination of above four indices was more accurate than one single variable in predicting PMV and had higher diagnostic value.
Résumé
Objectives: To describe the characteristics of a cohort of decannulated patients admitted to a Neuro-rehabilitation and Critical Care Center and their condition upon discharge. The secondary objective was to analyze the existence of possible risk factors associated with referral of patients to a high complexity center. Materials and Method: Descriptive, cross-sectional, retrospective study in the Clínica de Neurorehabilitación Santa Catalina, Autonomous City of Buenos Aires, Argentina. Results: 87 patients were decannulated. 29 patients were admitted with IMVA and could be completely weaned. The median of TQT days was 35 days (IQR 22-68). 21% of decannulated patients were still hospitalized at the institution upon the end of the study. 53% were discharged home alive, whereas 23% had to be referred to a high complexity center. Two decannulated patients died while they were hospitalized. Some variables independently associated with referral to a high complexity center were found, the presence of a neurological history before ICU admission (OR [odds ratio] = 4.22, 95% CI [confidence interval] (1.03-10.5), p = 0.02) and ICU admission for respiratory causes (OR = 4.44, 95% CI (1.22-16.1), p = 0.02). Conclusion: Most decannulated patients were discharged home alive. Neurological history and respiratory disease as reasons for ICU admission could be risk factors to be referred to a high complexity center.

The CoVID-19 pandemic may limit health resources in the hospital setting for the management of seriously ill patients, mainly adults; For this reason, strategies should be established from the pediatric field, which can consequently have an impact on the number of beds usually assigned to the child population. Of the patients who use prolonged mechanical ventilation, a significant number are managed at home, being considered to be at high risk of hospitalization and complications; on the other hand, there are some of them that remain institutionalized for clinical and / or social reasons. This article aims to provide guidelines for its safe handling both at home and in the pediatric services of our country, during times of pandemic CoVID - 19.
La pandemia de CoVID-19, puede limitar el recurso en salud en el escenario intrahospitalario para el manejo de pacientes graves, principalmente adultos; por lo cual se deben establecer estrategias desde el ámbito pediátrico, que pueden repercutir consecuentemente en los días camas destinados habitualmente a la población infantil. De los pacientes que emplean ventilación mecánica prolongada, un número importante es manejado en domicilio, siendo considerados de alto riesgo de hospitalización y complicaciones; por otro lado, existen algunos de ellos que permanecen institucionalizados por razones clínicas y/o sociales. Este artículo pretende entregar orientaciones para su manejo seguro, tanto en domicilio como en los servicios de pediatría de nuestro país, durante tiempos de pandemia CoVID 19.

Despite the great improvements in the techniques and perioperative management of liver transplantation in recent years, there are still several perioperative complications that may lead to the poor prognosis of recipients. Prolonged mechanical ventilation (PMV) is a common complication in the early stage after surgery and may result in a high incidence rate of postoperative complications, prolonged length of stay in the intensive care unit and hospital stay, and an increase in mortality rate. In recent years, many studies have reported PMV after liver transplantation, but no summarization and statistical analysis have been performed and there are still no effective measures to prevent PMV after liver transplantation. This article summarizes the influencing factors and interventions for PMV after liver transplantation, in order to provide valuable information for reducing the duration of mechanical ventilation after liver transplantation and improving the prognosis of liver transplantation recipients.

To identify the predictors of prolonged mechanical ventilation in patients undergoing surgery for stanford type A acute aortic dissection. Methods 202 patients who underwent surgery for acute aortic dissection type A from May 2009 to May 2016 were divided into two groups based on their mechanical ventilation time after surgery, including 70 patients with mechanical ventilation 48 hours or more(group A), 132 patients with mechanical ventilation less than 48 hours (group B). Univariate and multivariate analysis(logistic regression) were used to identify the predictive risk factors. Results The mechanical ventilation time was(146. 8 ±78. 5)h and(21. 7 ±9. 5)h in group A and group B respectively. Overall inhospital mortality was 8. 6% and 2. 3%. Multivariate logistic analysis showed that BMI(OR = 5. 956, 95% CI: 2. 585 - 13. 723, P =0. 000), CPB time(OR =1. 108, 95%CI: 1. 052 -1. 166, P =0. 000), DHCA(OR =4. 562, 95% CI: 1. 250 - 16. 640, P =0. 022), red blood cell transfusion intraoperative and in 24 hours postoperatively(OR =2. 625, 95% CI: 1. 515 -4. 549, P =0. 001) were the independent predictors for prolonged mechanical ventilation. Conclusion The incidence of prolonged mechanical ventilation is high after surgery for stanford type A acute aortic dissection. It can be predicted based on above factors, for patients with these risk factors, more perioperative care strategies are needed in order to shorten the mechanical ventilation time.
Résumé
@#Post operational recovery from cardiac surgery can be affected by many factors, including preoperative, intraoperative, and postoperative factors. Prolonged mechanical ventilation (PMV) , one of the major complications, has been widely accepted as a measure to evaluate the performance and outcomes of cardiac surgeries. Great progress has been made in the studies of risk factors contributing to PMV following cardiac surgeries in recent years. However, no clear and effective measures and approaches are available yet to prevent PMV. In this review, the authors try to summarize the risk factors that are associated with PMV throughout the perioperative period of cardiac surgery, as well as possible interventions when applicable.

Methods This study was a retrospective,single center study. One hundred and twenty patients with transposition of great arteries and intact ventricular septum who underwent primary arterial switch operation between January 2014 and December 2016 at Fuwai Hospital were eligible for this study. The data of patients from pediatric intensive care unit database and electronic medical records were collected. The data related to postoperative respiratory assist time were collected,including demo-graphic data,preoperative diagnosis,intraoperative data,and postoperative recovery data. The patients were divided into 2 groups according to ventilation time which were prolonged mechanical ventilation group(ventilation time > 72 hours) and non - prolonged mechanical ventilation group(ventilation time ≤72 hours). The data of 2 groups were analyzed by using single factor analysis,and the P≤0. 2 factors were processed into Logistic regression analysis. Results Ninety -six patients were enrolled including 22 patients in prolonged ventilation group and 74 patients in non - prolonged me-chanical ventilation group. No statistical significance was found in 2 groups in gender,age,weight,preoperative lactate, hemoglobin,use of prostaglandin E1,mechanical ventilation,cardiopulmonary time,aortic clamping time,the ratio of left ventricular pressure to right ventricular pressure,immediate postoperative plasma lactate,and vasoactive inotropic score. The weight and postoperative left atrial pressure were significantly different between 2 groups with P < 0. 2. Weight were (3. 5 ± 0. 9)kg in prolonged mechanical ventilation group and (3. 9 ± 1. 0)kg in non - prolonged mechanical ventila-tion group (P = 0. 117). Left atrial pressures were (7. 9 ± 1. 9)mmHg(1 mmHg = 0. 133 kPa)in prolonged mechani-cal ventilation group and (6. 7 ± 2. 0)mmHg in non - prolonged mechanical ventilation group(P = 0. 015). The weight and left atrial pressure were processed into Logistic regression analysis and the results revealed that high left atrial pres-sure was the risk factor for ventilation prolongation(OR = 1. 048,P = 0. 020). Respiratory assist time in prolonged and non - prolonged ventilation group was 112(80,194)h and 26(17,46)h,respectively;ICU time in prolonged and non - prolonged ventilation group was 10(1,14)d and 4(3,6)d,respectively;and all the differences were significant (all P = 0. 000). The number of death in each group was 1 with no significant difference(P = 0. 420). Conclusions High left atrial pressure is the risk factor for prolonged mechanical ventilation in children with transposition of great ar-teries and intact ventricular septum following primary arterial switch operation.
Résumé
El objetivo del presente trabajo fue describir la población que ingresó en un centro de desvinculación de la ventilación mecánica y rehabilitación (CDVMR) en asistencia ventilatoria mecánica invasiva (AVMi), analizar su evolución y determinar los predictores de fracaso de la desvinculación de la AVMi. Se revisaron las historias clínicas de 763 pacientes que ingresaron en el servicio de Cuidados Respiratorios, en el período comprendido entre mayo 2005 y enero 2012, se seleccionaron 372 con traqueotomía y AVMi. Se analizaron diferentes variables como posibles predictores de desvinculación. La media de edad fue 69 años (DS 14.7), 57% fueron hombres. La mediana de días de internación en la unidad de terapia intensiva (UTI) fue de 33 (rango intercuartilo-RQ 26-46). El 86% de los ingresados a UTI fue por causa médica. Durante la internación en el CDVMR lograron desvincularse el 50%; mediana de días de desvinculación, 13 (RQ 5-38). La edad fue predictor de fracaso de desvinculación. Al estudiar a la subpoblación con desvinculación parcial, se sumó el antecedente de EPOC como predictor. Si bien un 25% de los pacientes falleció o requirió derivación a un centro de mayor complejidad antes de 2 semanas de internación, más de la mitad de los pacientes lograron ser desvinculados definitivamente de la AVMi; esto podría sustentar la atención de pacientes críticos crónicos en CDVMR en la Argentina, ya que los pacientes internados en estos centros tienen buena expectativa de desvinculación, a pesar de las altas chances de desarrollar complicaciones.
The aim of this study was to describe the population admitted to a weaning center (WC) to receive invasive mechanical ventilation (MV), analyze their evolution and identify weaning failure predictors. The medical records of 763 patients admitted to the respiratory care service in the period between May 2005 and January 2012 were reviewed; 372 were selected among 415 tracheotomized and mechanically ventilated. Different variables were analyzed as weaning failure predictors. The mean age of patients admitted was 69 years (SD 14.7), 57% were men. The median length of hospitalization in ICU was 33 days (IQR 26-46). Admission to ICU was due to medical causes in 86% of cases. During hospitalization in WC 186 (50%) patients achieved the successful weaning at a median of 13 days (interquartile range-IQR 5-38). A predictor of weaning failure was age. When we studied the subpopulation with partial disconnection of mechanical ventilation, we found a history of COPD and ageas predictors. Although 25% of the patients died, or required referral to a center of major complexity before 2 weeks of hospitalization, more than half of the patients were able to be removed permanently from the invasive mechanical ventilation (MV), this could support the care of chronic critical patients in MV and rehabilitation centers in Argentina because patients in these centers have a chance of weaning from MV, despite the high chances of developing complications.

Desde que a ventilação mecânica foi difundida após a epidemia de poliomielite até os dias atuais com o avanço das estratégias diagnósticas e terapêuticas, houve significativo aumento na sobrevida dos pacientes criticamente enfermos. Este subgrupo de sobreviventes encontra-se em um estado cronicamente crítico e dentre outras disfunções e terapias de suporte, caracteriza-se pela necessidade de ventilação mecânica prolongada. Paralelo a este fato, o envelhecimento populacional eleva a chance de internações hospitalares com necessidade de assistência ventilatória invasiva. Nos dias de hoje, a ventilação mecânica domiciliar é uma realidade e tornou-se uma opção viável para pacientes com insuficiência respiratória crônica, também estimulada pelo crescimento da utilização de ventilação não invasiva com pressão positiva, o reconhecimento de diferentes tipos de pacientes que podem se beneficiar desta técnica e redução dos custos hospitalares através da desospitalização.Atualmente possuímos diversos tipos e modelos de ventiladores exclusivos para ventilação mecânica domiciliar, assim como interfaces e a escolha do dispositivo ideal para cada paciente pode ser uma tarefa árdua. Porém não pode ser esquecido que o objetivo principal da utilização da ventilação domiciliar deve ser o controle dos sintomas decorrentes da doença do paciente e consequente melhora da qualidade de vida...
Since mechanical ventilation was widespread after the polio epidemic to the present day with the advancement of diagnostic and therapeutic strategies, a significant increase in survival of critically ill patients. This subgroup of survivors is in a critical state and chronically various etiologies and therapies support, characterized by the need for prolonged mechanical ventilation. Parallel to this fact, population aging increases the chance of hospitalizations requiring invasive mechanical ventilation. Today, home mechanical ventilation is a reality and has become a viable option for patients with chronic respiratory insufficiency, also encouraged by the increasing use of noninvasive positive pressure ventilation, recognition of different types of patients who may benefit from this technique and reduced hospital costs through deinstitutionalization.We currently have various types and models of home mechanical ventilatiors, as well as interfaces and choosing the right device for each patient can be a chore. But it can not be forgotten that the main purpose of using home ventilation is to control the symptoms of the patients illness and consequent improvement in quality of life...
