Objective To obtain data on bed refusal in intensive care units in Brazil and to evaluate the use of triage systems by professionals. Methods A cross-sectional survey. Using the Delphi methodology, a questionnaire was created contemplating the objectives of the study. Physicians and nurses enrolled in the research network of the Associação de Medicina Intensiva Brasileira (AMIBnet) were invited to participate. A web platform (SurveyMonkey®) was used to distribute the questionnaire. The variables in this study were measured in categories and expressed as proportions. The chi-square test or Fisher’s exact test was used to verify associations. The significance level was set at 5%. Results In total, 231 professionals answered the questionnaire, representing all regions of the country. The national intensive care units had an occupancy rate of more than 90% always or frequently for 90.8% of the participants. Among the participants, 84.4% had already refused admitting patients to the intensive care unit due to the capacity of the unit. Half of the Brazilian institutions (49.7%) did not have triage protocols for admission to intensive beds. Conclusions Bed refusal due to high occupancy rates is common in Brazilian intensive care units. Even so, half of the services in Brazil do not adopt protocols for triage of beds.

Objective To investigate the influence of a passive mobilization session on endothelial function in patients with sepsis. Methods This was a quasi-experimental double-blind and single-arm study with a pre- and postintervention design. Twenty-five patients with a diagnosis of sepsis who were hospitalized in the intensive care unit were included. Endothelial function was assessed at baseline (preintervention) and immediately postintervention by brachial artery ultrasonography. Flow mediated dilatation, peak blood flow velocity and peak shear rate were obtained. Passive mobilization consisted of bilateral mobilization (ankles, knees, hips, wrists, elbows and shoulders), with three sets of ten repetitions each, totaling 15 minutes. Results After mobilization, we found increased vascular reactivity function compared to preintervention: absolute flow-mediated dilatation (0.57mm ± 0.22 versus 0.17mm ± 0.31; p < 0.001) and relative flow-mediated dilatation (17.1% ± 8.25 versus 5.08% ± 9.16; p < 0.001). Reactive hyperemia peak flow (71.8cm/s ± 29.3 versus 95.3cm/s ± 32.2; p < 0.001) and shear rate (211s ± 113 versus 288s ± 144; p < 0.001) were also increased. Conclusion A passive mobilization session increases endothelial function in critical patients with sepsis. Future studies should investigate whether a mobilization program can be applied as a beneficial intervention for clinical improvement of endothelial function in patients hospitalized due to sepsis.
目的探讨被动活动对脓毒症患者内皮功能的影响。方法采用准实验双盲单臂研究,采用干预前后设计。在重症监护室住院的25例诊断为败血症的患者被纳入研究。在基线(干预前)和干预后立即通过肱动脉超声检查评估内皮功能。得到血流介导的扩张、血流速度峰值和剪切速率峰值。被动活动包括双侧活动(脚踝、膝盖、臀部、手腕、肘部和肩部),每组重复10次,共15分钟。结果与干预前相比,活动后血管反应性功能增强:血流介导的绝对扩张(0.57mm±0.22 vs 0.17mm±0.31);P < 0.001)和相对血流介导的舒张(17.1%±8.25 vs 5.08%±9.16;P < 0.001)。反应性充血峰值流量(71.8cm/s±29.3 vs 95.3cm/s±32.2;P < 0.001)和剪切速率(211s±113比288s±144;P < 0.001)。结论被动活动可提高重症脓毒症患者的内皮功能。未来的研究应探讨动员方案是否可以作为一种有益的干预措施,用于脓毒症住院患者内皮功能的临床改善。

Unwittingly, hypoxemia may persist or even supervene after a patient is placed on veno-venous extracorporeal membrane lung oxygenation (VV-ECMO) for refractory hypoxemia. According to Extracorporeal Life Support Organization (ELSO) guidelines, the threshold for adequate arterial O2 saturation is > 80 85%,(1) while a value > 88% has been considered the threshold in other guidelines.(2) Although the exact incidence is difficult to ascertain and the definition itself may vary, hypoxemia during VV-ECMO requires both systematic assessment and prompt optimization of modifiable variables, as it has been associated with increased mortality.(3) To fully understand why hypoxemia still occurs, one has to consider the principles underpinning the ability of ECMO to ensure adequate oxygen (O2) transfer across the membrane lung and into the patient’s blood. First, there is a fraction of oxygen in the fresh sweep gas that can be set, usually at 1.0. Second, a membrane lung, with an appropriate surface area available for gas exchange, needs to be working properly, allowing unimpeded blood flow around the gas-containing polymer microfibers. Third, the absolute amount of blood flowing through the oxygenator (QECMO) and its relative proportion to the patient’s own cardiac output (Qpatient) need to be considered. Finally, the fraction of oxygenated blood flowing through ECMO that does not go into the pulmonary circulation but instead recirculates into the drainage cannula impacts the oxygenating efficacy of VV-ECMO.(4) In a concept study, Schmidt et al. clearly demonstrated that blood flow through the ECMO circuit is the key determinant of blood oxygenation.(5) Furthermore, as a higher proportion of deoxygenated venous blood goes through the patient’s right heart than through the ECMO circuit, the QECMO/Qpatient quotient falls below the boundary of 0.6, and the O2 content of arterial blood will drop even if the absolute blood flow through the membrane lung is appropriate to the body surface area.(5) This is especially important if the degree of pulmonary shunt is such that any residual lung function contributing to oxygenation is negligible, which frequently occurs in patients being considered for VV-ECMO.(4) To overcome persistent hypoxemia, different strategies have been devised. Among them, the most immediate would be to increase the QECMO/Qpatient ratio. Typical ECMO rated flows, which is the maximal flow at which hemoglobin [12g/ dL] is fully saturated at the membrane outlet, are ~7L/minute. In these extreme situations, when a patient with no lung contribution and very high cardiac output has persistent severe hypoxemia or hypercarbia, adding a second oxygenator to the extracorporeal circuit, whether in parallel or in series, might be an intuitive option. In this issue of the Revista Brasileira de Terapia Intensiva, Melro et al.,(6) using a porcine model, evaluated the impact on blood oxygenation of these two circuit configurations.

由于难治性低氧血症,患者接受静脉-静脉体外膜肺氧合(VV-ECMO)治疗后,低氧血症可能在不知不觉中持续存在,甚至出现。根据体外生命支持组织(ELSO)指南,动脉血氧饱和度阈值为> - 80 - 85%,(1)而> - 88%在其他指南中被认为是阈值。(2)尽管确切的发生率难以确定,其定义本身也可能有所不同,但VV-ECMO期间低氧血症需要系统评估和及时优化可修改变量。(3)为了充分理解为什么低氧血症仍然会发生,我们必须考虑ECMO的基本原理,以确保足够的氧气(O2)通过膜肺转移到患者的血液中。首先,在新鲜的扫气中有一小部分氧气可以设定,通常为1.0。其次,膜肺需要有适当的表面积用于气体交换,它需要正常工作,允许血液在含气体的聚合物微纤维周围畅通无阻地流动。第三,需要考虑流经氧合器的绝对血流量(QECMO)及其与患者自身心输出量(Qpatient)的相对比例。最后,流经ECMO的含氧血液中不进入肺循环而是再循环进入引流管的比例会影响VV-ECMO的氧合效果。(4)在一项概念研究中,Schmidt等人清楚地证明,通过ECMO回路的血流是血液氧合的关键决定因素。(5)此外,由于通过患者右心的缺氧静静脉血液比例高于通过ECMO回路的比例,QECMO/Qpatient商低于0.6,即使膜肺的绝对血流量与体表面积相当,动脉血氧含量也会下降。(5)如果肺分流的程度使得任何有助于氧合的残余肺功能都可以忽略不计,这一点尤其重要,这种情况经常发生在考虑进行VV-ECMO的患者中。(4)为了克服持续低氧血症,已经设计了不同的策略。其中,最直接的是提高QECMO/Qpatient比率。典型的ECMO额定流量为~7L/min,即血红蛋白[12g/ dL]在膜出口完全饱和时的最大流量。在这些极端情况下,当患者无肺贡献和非常高的心输出量持续严重低氧血症或高碳血症时,在体外回路中添加第二个氧合器,无论是并联还是串联,可能是一个直观的选择。在这一期的Revista Brasileira de Terapia Intensiva中,Melro等人(6)使用猪模型评估了这两种回路配置对血氧的影响。此外,还分析了脱羧效果,以及由第二个氧合器的“虚拟”存在对电路施加的压力和电阻变化。为了实现这一目标,作者在自己之前的工作(7)的基础上,使用一个经过验证的数学模型,计算不同ECMO流量下的外周动脉氧饱和度、氧合后氧含量和动脉二氧化碳分压(PaCO2),同时保持其余变量不变(肺分流分数、呼吸机吸入氧分数[FiO2]、心输出量、扫气流量、扫气流量O2分数、血红蛋白浓度、O2消耗和CO2产生)。António tralh 1, Philip Fortuna2

Objective: To compare the perceptions of patients' relatives with the perceptions of health professionals regarding a flexible visitation model in intensive care units.
Methods: Cross-sectional study. This study was carried out with patients' relatives and members of the care team of a clinical-surgical intensive care unit with a flexible visitation model (12 hours/day) from September to December 2018. The evaluation of the flexible visitation policy was carried out through an open visitation instrument composed of 22 questions divided into three domains (evaluation of family stress, provision of information, and interference in the work of the team).
Results: Ninety-five accompanying relatives and 95 members of the care team were analyzed. The perceptions of relatives regarding the decrease in anxiety and stress with flexible visitation was higher than the perceptions of the team (91.6% versus 58.9%, p < 0.001), and the family also had a more positive perception regarding the provision of information (86.3% versus 64.2%, p < 0.001). The care team believed that the presence of the relative made it difficult to provide care to the patient and caused work interruptions (46.3% versus 6.3%, p < 0.001).
Conclusion: Family members and staff-intensive care unit teams have different perceptions about flexible visits in the intensive care unit. However, a positive view regarding the perception of decreased anxiety and stress among the family members and greater information and contributions to patient recovery predominates.

Objective: To evaluate clinical practices and hospital resource organization during the early COVID-19 pandemic in Brazil.
Methods: This was a multicenter, cross-sectional survey. An electronic questionnaire was provided to emergency department and intensive care unit physicians attending COVID-19 patients. The survey comprised four domains: characteristics of the participants, clinical practices, COVID-19 treatment protocols and hospital resource organization.
Results: Between May and June 2020, 284 participants [median (interquartile ranges) age 39 (33 - 47) years, 56.3% men] responded to the survey; 33% were intensivists, and 9% were emergency medicine specialists. Half of the respondents worked in public hospitals. Noninvasive ventilation (89% versus 73%; p = 0.001) and highflow nasal cannula (49% versus 32%; p = 0.005) were reported to be more commonly available in private hospitals than in public hospitals. Mechanical ventilation was more commonly used in public hospitals than private hospitals (70% versus 50%; p = 0,024). In the Emergency Departments, positive endexpiratory pressure was most commonly adjusted according to SpO2, while in the intensive care units, positive end-expiratory pressure was adjusted according to the best lung compliance. In the Emergency Departments, 25% of the respondents did not know how to set positive end-expiratory pressure. Compared to private hospitals, public hospitals had a lower availability of protocols for personal protection equipment during tracheal intubation (82% versus 94%; p = 0.005), managing mechanical ventilation [64% versus 75%; p = 0.006] and weaning patients from mechanical ventilation [34% versus 54%; p = 0.002]. Finally, patients spent less time in the emergency department before being transferred to the intensive care unit in private hospitals than in public hospitals [2 (1 - 3) versus 5 (2 - 24) hours; p < 0.001].
Conclusion: This survey revealed significant heterogeneity in the organization of hospital resources, clinical practices and treatments among physicians during the early COVID-19 pandemic in Brazil.

Objective: To evaluate the incidence of risk factors for postintubation hypotension in critically ill patients with COVID-19.
Methods: We conducted a retrospective study of 141 patients with COVID-19 who were intubated in the intensive care unit. Postintubation hypotension was defined as the need for any vasopressor dose at any time within the 60 minutes following intubation. Patients with intubation-related cardiac arrest and hypotension before intubation were excluded from the study.
Results: Of the 141 included patients, 53 patients (37.5%) had postintubation hypotension, and 43.6% of the patients (n = 17) were female. The median age of the postintubation hypotension group was 75.0 (interquartile range: 67.0 - 84.0). In the multivariate analysis, shock index ≥ 0.90 (OR = 7.76; 95%CI 3.14 - 19.21; p < 0.001), albumin levels < 2.92g/dL (OR = 3.65; 95%CI 1.49 - 8.96; p = 0.005), and procalcitonin levels (OR = 1.07, 95%CI 1.01 - 1.15; p = 0.045) were independent risk factors for postintubation hypotension. Hospital mortality was similar in patients with postintubation hypotension and patients without postintubation hypotension (92.5% versus 85.2%; p = 0.29).
Conclusion: The incidence of postintubation hypotension was 37.5% in critically ill COVID-19 patients. A shock index ≥ 0.90 and albumin levels < 2.92g/dL were independently associated with postintubation hypotension. Furthermore, a shock index ≥ 0.90 may be a practical tool to predict the increased risk of postintubation hypotension in bedside scenarios before endotracheal intubation. In this study, postintubation hypotension was not associated with increased hospital mortality in COVID-19 patients.

Objective: The current study assessed the prevalence of troponin elevation and its capacity to predict 60day mortality in COVID-19 patients in intensive care. Methods: A longitudinal prospective single-center study was performed on a cohort of patients in intensive care due to a COVID-19 diagnosis confirmed using real-time test polymerase chain reaction from May to December 2020. A Receiver Operating Characteristic curve was constructed to predict death according to troponin level by calculating the area under the curve and its confidence intervals. A Cox proportional hazards model was generated to report the hazard ratios with confidence intervals of 95% and the p value for its association with 60day mortality. Results: A total of 296 patients were included with a 51% 60-day mortality rate. Troponin was positive in 39.9% (29.6% versus 49.7% in survivors and non-survivors, respectively). An area under the curve of 0.65 was found (95%CI: 0.59 - 0.71) to predict mortality. The Cox univariate model demonstrated a hazard ratio of 1.94 (95%CI: 1.41 - 2.67) and p < 0.001, but this relationship did not remain in the multivariate model, in which the hazard ratio was 1.387 (95%CI: 0.21 - 1.56) and the p value was 0.12. Conclusion: Troponin elevation is frequently found in patients in intensive care for COVID-19. Although its levels are higher in patients who die, no relationship was found in a multivariate model, which indicates that troponin should not be used as an only prognostic marker for mortality in this population.

Objective: The TELE-critical Care verSus usual Care On ICU PErformance (TELESCOPE) trial aims to assess whether a complex telemedicine intervention in intensive care units, which focuses on daily multidisciplinary rounds performed by remote intensivists, will reduce intensive care unit length of stay compared to usual care. Methods: The TELESCOPE trial is a national, multicenter, controlled, open label, cluster randomized trial. The study tests the effectiveness of daily multidisciplinary rounds conducted by an intensivist through telemedicine in Brazilian intensive care units. The protocol was approved by the local Research Ethics Committee of the coordinating study center and by the local Research Ethics Committee from each of the 30 intensive care units, following Brazilian legislation. The trial is registered with ClinicalTrials. gov (NCT03920501). The primary outcome is intensive care unit length of stay, which will be analyzed accounting for the baseline period and cluster structure of the data and adjusted by prespecified covariates. Secondary exploratory outcomes included intensive care unit performance classification, in-hospital mortality, incidence of nosocomial infections, ventilator-free days at 28 days, rate of patients receiving oral or enteral feeding, rate of patients under light sedation or alert and calm, and rate of patients under normoxemia. Conclusion: According to the trial’s best practice, we report our statistical analysis prior to locking the database and beginning analyses. We anticipate that this reporting practice will prevent analysis bias and improve the interpretation of the reported results. ClinicalTrials.gov registration: NCT03920501
