RESUMO

OBJECTIVES: Concise "synthetic" review of the state of the art of management of acute ischemic stroke. DATA SOURCES: Available literature on PubMed. STUDY SELECTION: We selected landmark studies, recent clinical trials, observational studies, and professional guidelines on the management of stroke including the last 10 years. DATA EXTRACTION: Eligible studies were identified and results leading to guideline recommendations were summarized. DATA SYNTHESIS: Stroke mortality has been declining over the past 6 decades, and as a result, stroke has fallen from the second to the fifth leading cause of death in the United States. This trend may follow recent advances in the management of stroke, which highlight the importance of early recognition and early revascularization. Recent studies have shown that early recognition, emergency interventional treatment of acute ischemic stroke, and treatment in dedicated stroke centers can significantly reduce stroke-related morbidity and mortality. However, stroke remains the second leading cause of death worldwide and the number one cause for acquired long-term disability, resulting in a global annual economic burden. CONCLUSIONS: Appropriate treatment of ischemic stroke is essential in the reduction of mortality and morbidity. Management of stroke involves a multidisciplinary approach that starts and extends beyond hospital admission.

RESUMO

OBJECTIVES: In 2014, the Tele-ICU Committee of the Society of Critical Care Medicine published an article regarding the state of ICU telemedicine, one better defined today as tele-critical care. Given the rapid evolution in the field, the authors now provide an updated review. DATA SOURCES AND STUDY SELECTION: We searched PubMed and OVID for peer-reviewed literature published between 2010 and 2018 related to significant developments in tele-critical care, including its prevalence, function, activity, and technologies. Search terms included electronic ICU, tele-ICU, critical care telemedicine, and ICU telemedicine with appropriate descriptors relevant to each sub-section. Additionally, information from surveys done by the Society of Critical Care Medicine was included given the relevance to the discussion and was referenced accordingly. DATA EXTRACTION AND DATA SYNTHESIS: Tele-critical care continues to evolve in multiple domains, including organizational structure, technologies, expanded-use case scenarios, and novel applications. Insights have been gained in economic impact and human and organizational factors affecting tele-critical care delivery. Legislation and credentialing continue to significantly influence the pace of tele-critical care growth and adoption. CONCLUSIONS: Tele-critical care is an established mechanism to leverage critical care expertise to ICUs and beyond, but systematic research comparing different models, approaches, and technologies is still needed.

RESUMO

BACKGROUND: Emergence of the novel corona virus (severe acute respiratory syndrome (SARS)-CoV-2) in December 2019 has led to the COVID-19 pandemic. The extent of COVID-19 involvement in the central nervous system is not well established, and the presence or the absence of SARS-CoV-2 particles in the cerebrospinal fluid (CSF) is a topic of debate. CASE DESCRIPTION: We present two patients with COVID-19 and concurrent neurological symptoms. Our first patient is a 31-year-old man who had flu-like symptoms due to COVID-19 and later developed an acute-onset severe headache and loss of consciousness and was diagnosed with a Hunt and Hess grade 3 subarachnoid haemorrhage from a ruptured aneurysm. Our second patient is a 62-year-old woman who had an ischaemic stroke with massive haemorrhagic conversion requiring a decompressive hemicraniectomy. Both patients' CSF was repeatedly negative on real-time PCR analysis despite concurrent neurological disease. CONCLUSION: Our report shows that patients' CSF may be devoid of viral particles even when they test positive for COVID-19 on a nasal swab. Whether SARS-CoV-2 is present in CSF may depend on the systemic disease severity and the degree of the virus' nervous tissue tropism and should be examined in future studies.

RESUMO

Malnutrition is frequently seen among patients in the intensive care unit. Evidence shows that optimal nutritional support can lead to better clinical outcomes. Recent clinical trials debate over the efficacy of enteral nutrition (EN) over parenteral nutrition (PN). Multiple trials have studied the impact of EN versus PN in terms of health-care cost and clinical outcomes (including functional status, cost, infectious complications, mortality risk, length of hospital and intensive care unit stay, and mechanical ventilation duration). The aim of this review is to address the question: In critically ill adult patients requiring nutrition support, does EN compared to PN favorably impact clinical outcomes and health-care costs?

RESUMO

OBJECTIVE: Research on continuous electro-encephalographic monitoring (cEEG) in the intensive care unit (ICU) has previously focused on neuroscience ICUs. This study determines cEEG utilization within a sample of specialty ICUs world-wide. METHODS: A cross-sectional electronic survey of attending level physicians across various intensive care settings. Twenty-five questions developed from consensus statements on the use of cEEG in the critically ill sent as an electronic survey. RESULTS: Of all, 9344 were queried and 417 (4.5%) responses were analyzed with 309 (74%) from the United States and 74 (18%) internationally. Intensive care units were: medical (10%), surgical (6%), neurologic/neurosurgical (12%), cardiac (4%), trauma (3%), pediatrics (29%), burn (<1%), multidisciplinary (30%), and other (5%). Intensive care units were: academic (65%), community (18%), public (3%), military (1%), and other (13%). Specialized cEEG teams were available in 71% of ICUs. Rapid 24/7 access and cEEG interpretation was available in 32% of ICUs. Interpretation changed clinical management frequently (28%) and sometimes (45%). CONCLUSIONS: Despite guideline recommendations for cEEG use, there is a discordance between availability, night coverage, and immediate interpretation. Only 27% have institutional protocols for indications and duration of cEEG monitoring. Furthermore, cEEG may be underutilized in nonneurologic ICUs as well as ICUs in smaller nonacademic affiliated hospitals and those outside of the United States.

RESUMO

OBJECTIVE: This manuscript describes the state of neurocritical care fellowship training, compares its written standards to those of other critical care fellowship programs, and discusses how programmatic oversight by the United Council for Neurological Subspecialties should evolve to meet American College of Graduate Medical Education standards. This review is a work product of the Society of Critical Care Medicine Neuroscience section and was reviewed and approved by the Council of the Society of Critical Care Medicine. DATA SOURCES: We evaluated the published training criteria and requirements of American College of Graduate Medical Education Critical Care subspecialty fellowships programs of Internal Medicine, Surgery, and Anesthesia and compared them with the training criteria and required competencies for neurocritical care. STUDY SELECTION: We have reviewed the published training standards from American College of Graduate Medical Education as well as the United Council for Neurologic Subspecialties subspecialty training documents and clarified the definition and responsibilities of an intensivist with reference to the Leapfrog Group, the National Quality Forum, and the Joint Commission. DATA EXTRACTION: No data at present exist to test the concept of similarity across specialty fellowship critical care training programs. DATA SYNTHESIS: Neurocritical care training differs in its exposure to clinical entities that are directly associated to other critical care subspecialties. However, the core critical care knowledge, procedural skills, and competencies standards for neurocritical care appears to be similar with some important differences compared with American College of Graduate Medical Education critical care training programs. CONCLUSIONS: The United Council for Neurologic Subspecialties has developed a directed program development strategy to emulate American College of Graduate Medical Education standards with the goal to have standards that are similar or identical to American College of Graduate Medical Education standards.

RESUMO

As medical decisions fall under more scrutiny and society demands increasing transparency of care, it is likely that more opportunities for conflicts will emerge. Similarly, with increasing demand and a static supply, the issue of who receives treatment and for how long naturally will arise. This mismatch leads to discussions of resource utilization and limitation of care in light of patients' values and rights. Clinicians should always be forthcoming with the uncertainty of prognostication while also articulating the severity of a patient's disease in relation to the risk and benefits of an intervention. However, dispute over treatment course and the idea of futile care can arise for in a variety of reasons, both from the clinician and the patient. Without identifying the cause of these conflicts, it is impossible to have effective communication. At times, it is important to utilize various negotiating skills when resolving these disagreements. Regardless of the approach, practitioners need more training in and exposure to these types of conflicts. In this review, we provide a framework for the origins and current state of futility, challenges in the application of the term, and recommendations on how to approach conflict in these situations.

RESUMO

INTRODUCTION: Prolonged immobility in patients in the intensive care unit (ICU) can lead to muscle wasting and weakness, longer hospital stays, increased number of days in restraints, and hospital-acquired infections. Increasing evidence demonstrates the safety and feasibility of early mobilization in the ICU. However, there is a lack of evidence in the safety and feasibility of mobilizing patients with external ventricular drains (EVDs). The purpose of this study was to determine the safety and feasibility of early mobility in this patient population. METHODS: We conducted a prospective, observational study. All patients in the study were managed with standard protocols and procedures practiced in our ICU including early mobility. Patients with an EVD who received early mobilization were awake and following commands, had a Lindegaard ratio <3.0 or middle cerebral artery (MCA) mean flow velocity <120 cm/s, a Mean Arterial Pressure (MAP) > 80 mm Hg, and an intracranial pressure consistently <20 mm Hg. Data were collected by physical therapists at the time of encounter. RESULTS: Ninety patients with a total of 185 patient encounters were recorded over a 12-month period. The average time between EVD placement and physical therapy (PT) session was 8.3 ± 5.5 days. In 149 (81%) encounters, patients were at least standing or better. Patients were walking with assistance or better in 99 (54%) encounters. There were 4 (2.2%) adverse events recorded during the entire study. CONCLUSION: This observational study suggests that PT is feasible in patients with EVDs and can be safely tolerated. Further research is warranted in a larger patient population conducted prospectively to assess the potential benefit of early mobility in this patient population.

RESUMO

OBJECTIVES: The Society of Critical Care Medicine and four other major critical care organizations have endorsed a seven-step process to resolve disagreements about potentially inappropriate treatments. The multiorganization statement (entitled: An official ATS/AACN/ACCP/ESICM/SCCM Policy Statement: Responding to Requests for Potentially Inappropriate Treatments in Intensive Care Units) provides examples of potentially inappropriate treatments; however, no clear definition is provided. This statement was developed to provide a clear definition of inappropriate interventions in the ICU environment. DESIGN: A subcommittee of the Society of Critical Care Medicine Ethics Committee performed a systematic review of empirical research published in peer-reviewed journals as well as professional organization position statements to generate recommendations. Recommendations approved by consensus of the full Society of Critical Care Medicine Ethics Committees and the Society of Critical Care Medicine Council were included in the statement. MEASUREMENTS AND MAIN RESULTS: ICU interventions should generally be considered inappropriate when there is no reasonable expectation that the patient will improve sufficiently to survive outside the acute care setting, or when there is no reasonable expectation that the patient's neurologic function will improve sufficiently to allow the patient to perceive the benefits of treatment. This definition should not be considered exhaustive; there will be cases in which life-prolonging interventions may reasonably be considered inappropriate even when the patient would survive outside the acute care setting with sufficient cognitive ability to perceive the benefits of treatment. When patients or surrogate decision makers demand interventions that the clinician believes are potentially inappropriate, the seven-step process presented in the multiorganization statement should be followed. Clinicians should recognize the limits of prognostication when evaluating potential neurologic outcome and terminal cases. At times, it may be appropriate to provide time-limited ICU interventions to patients if doing so furthers the patient's reasonable goals of care. If the patient is experiencing pain or suffering, treatment to relieve pain and suffering is always appropriate. CONCLUSIONS: The Society of Critical Care Medicine supports the seven-step process presented in the multiorganization statement. This statement provides added guidance to clinicians in the ICU environment.

RESUMO

Acute brain and spinal cord injuries affect hundreds of thousands of people worldwide. Though advances in pre-hospital and emergency and neurocritical care have improved the survival of some to these devastating diseases, very few clinical trials of potential neuro-protective strategies have produced promising results. Medical therapies such as targeted temperature management (TTM) have been trialed in traumatic brain injury (TBI), spinal cord injury (SCI), acute ischemic stroke (AIS), subarachnoid hemorrhage (SAH), and intracranial hemorrhage (ICH), but in no study has a meaningful effect on outcome been demonstrated. To this end, patient selection for potential neuro-protective therapies such as TTM may be the most important factor to effectively demonstrate efficacy in clinical trials. The use of TTM as a strategy to treat and prevent secondary neuronal damage in the intraoperative setting is an area of ongoing investigation. In this review we will discuss recent and ongoing studies that address the role of TTM in combination with surgical approaches for different types of brain injury.

RESUMO

BACKGROUND: Approximately one-third of patients with isolated traumatic brain injury (iTBI) present with acute traumatic coagulopathy (ATC). ATC is associated with increased morbidity and mortality. Its effects on long-term functional and cognitive outcomes are not as well characterized. METHODS: Data from the Citicoline Brain Injury Treatment Trial (COBRIT) were analyzed retrospectively. Exclusion criteria were renal failure or malignancy, and any extracranial injury severity score >3. ATC was defined as INR > 1.3, PTT > 38 s, or platelets < 100 K, determined at baseline, and during the first 7 days of hospitalization. RESULTS: Six hundred forty-seven patients were included; 21 % were found to have ATC. Highest incidence occurred at baseline, and Day Two. Forty-two percent of ATC patients had a GCS < 8, compared with 11.3 % of non-ATC patients (p < 0.001). A significantly higher proportion of ATC patients was transfused blood products, required greater than 4L of fluids, demonstrated hyperthermia and hypothermia, were hypotensive and demonstrated elevated lactate when compared to non-ATC patients. In-hospital mortality, mean hospital length of stay, incidence of DVT and seizures were also significantly higher in ATC patients. A significantly lower portion of ATC patients had good outcomes on the GOS-E (i.e., score > 6), and the DRS (i.e., score < 2) at 180 days, for which ATC was found to be an independent predictor with binary logistic regression. ATC patients also performed significantly worse on several components of the CVLT-II at 180 days. CONCLUSIONS: ATC accompanying iTBI is associated with worse functional and cognitive outcomes at 180 days.

RESUMO

BACKGROUND: Deep-venous thrombosis (DVT) and pulmonary embolism (PE) are major causes of morbidity and mortality in patients with acute ischemic stroke. This study is the first to examine the risk of venous thromboembolism in patients with large hemispheric infarction undergoing decompressive hemicraniectomy. METHODS: The study population included 95 consecutive patients with a large hemispheric infarction who underwent decompressive hemicraniectomy between 2006 and 2014 at our institution. All patients received prophylactic unfractionated heparin and intermittent compression devices (SCD). Patients were systematically screened for DVT at 5-day interval using Duplex ultrasound. PE was diagnosed on chest CT angiography. RESULTS: Mean age was 57 ± 12 years; mean BMI was 28.3 ± 7.4 kg/m(2). 30.5 % of patients had infarction in the dominant hemisphere and 69.5 % in the non-dominant hemisphere. The mean NIHSS score was 16.0 ± 5 at admission. The mean length of stay was 22 ± 17 days. 35 % of patients developed a DVT including 27 % who developed above-knee DVT and required placement of an inferior vena cava filter. In multivariable analysis, predictors of DVT were an NIHSS ≥ 17 (p = 0.007), seizures (p = 0.003), hypertension (p = 0.03), and increasing length of stay (p = 0.01). The proportion of patients who developed PE was 13 %. In multivariate analysis, BMI ≥ 30 predicted PE (p = 0.05). CONCLUSIONS: The rate of DVT and PE is remarkably high in patients with large hemispheric infarction undergoing decompressive hemicraniectomy despite prophylactic measures. We recommend routine screening for DVT in this population. Interventions beyond the standard prophylactic measures may be necessary in this high-risk group.

RESUMO

Care of critically ill patients, as in any other field, demands the exercise of ethical principles related to respect of patient's autonomy, beneficence, nonmaleficence, and distributive justice. Professional duty and the common law require doctors to obtain consent before giving treatment or for requesting participation in clinical research. A procedure or research study must be adequately explained, and the patient must have the capacity to consent. If a patient does not have decision-making capacity, treatment must be given using alternative forms of consent or using principles of implied consent in emergency or life-threatening situations. In the case of clinical research, informed consent must always be sought. Exemptions to this rule are morally justified in circumstances related to research in life-threatening conditions or life-saving interventions in which the investigator departs from sound principles of equipoise. This usually implies the imposition of safeguards such as consultation with the community in which the study were to take place, oversight in patient screening and recruitment process by institutional review boards, special study designs, retrospective and prospective consent processes, and independent safety monitoring.

RESUMO

PURPOSE: To test the hypothesis that fever was more frequent in critically ill patients with brain injury when compared to nonneurological patients and to study its effect on in-hospital case fatality. METHODS: Retrospective matched cohort study utilizing a single-center prospectively compiled registry. Critically ill neurological patients ≥18 years and consecutively admitted to the intensive care unit (ICU) with acute ischemic stroke (AIS), intracerebral hemorrhage (ICH), and traumatic brain injury (TBI) were selected. Patients were matched by sex, age, and Acute Physiology and Chronic Health Evaluation II (APACHE-II) to a cohort of nonneurological patients. Fever was defined as any temperature ≥37.5°C within the first 24 hours upon admission to the ICU. The primary outcome measure was in-hospital case fatality. RESULTS: Mean age among neurological patients was 65.6 ± 15 years, 46% were men, and median APACHE-II was 15 (interquartile range 11-20). There were 18% AIS, 27% ICH, and 6% TBI. More neurological patients experienced fever than nonneurological patients (59% vs 47%, P = .007). The mean hospital length of stay was higher for nonneurological patients (18 ± 20 vs 14 ± 15 days, P = .007), and more neurological patients were dead at hospital discharge (29% vs 20%, P < .0001). After risk factor adjustment, diagnosis (neurological vs nonneurological), and the probability of being exposed to fever (propensity score), the following variables were associated with higher in-hospital case fatality: APACHE-II, neurological diagnosis, mean arterial pressure, cardiovascular and respiratory dysfunction in ICU, and fever (odds ratio 1.9, 95% confidence interval 1.04-3.6, P = .04). CONCLUSION: These data suggest that fever is a frequent occurrence after brain injury, and that it is independently associated with in-hospital case fatality.

RESUMO

Large hemispheric infarction (LHI), also known as malignant middle cerebral infarction, is a devastating disease associated with significant disability and mortality. Clinicians and family members are often faced with a paucity of high quality clinical data as they attempt to determine the most appropriate course of treatment for patients with LHI, and current stroke guidelines do not provide a detailed approach regarding the day-to-day management of these complicated patients. To address this need, the Neurocritical Care Society organized an international multidisciplinary consensus conference on the critical care management of LHI. Experts from neurocritical care, neurosurgery, neurology, interventional neuroradiology, and neuroanesthesiology from Europe and North America were recruited based on their publications and expertise. The panel devised a series of clinical questions related to LHI, and assessed the quality of data related to these questions using the Grading of Recommendation Assessment, Development and Evaluation guideline system. They then developed recommendations (denoted as strong or weak) based on the quality of the evidence, as well as the balance of benefits and harms of the studied interventions, the values and preferences of patients, and resource considerations.

RESUMO

OBJECTIVE: To test the hypothesis that hyperoxia was associated with higher in-hospital mortality in ventilated stroke patients admitted to the ICU. DESIGN: Retrospective multicenter cohort study. SETTING: Primary admissions of ventilated stroke patients with acute ischemic stroke, subarachnoid hemorrhage, and intracerebral hemorrhage who had arterial blood gases within 24 hours of admission to the ICU at 84 U.S. ICUs between 2003 and 2008. Patients were divided into three exposure groups: hyperoxia was defined as PaO2 ≥ 300 mm Hg (39.99 kPa), hypoxia as any PaO2<60 mm Hg (7.99 kPa) or PaO2/FiO2 ratio ≤ 300, and normoxia, not defined as hyperoxia or hypoxia. The primary outcome was in-hospital mortality. PARTICIPANTS: Two thousand eight hundred ninety-four patients. METHODS: Patients were divided into three exposure groups: hyperoxia was defined as PaO2 more than or equal to 300 mm Hg (39.99 kPa), hypoxia as any PaO2 less than 60 mm Hg (7.99 kPa) or PaO2/FIO2 ratio less than or equal to 300, and normoxia, not defined as hyperoxia or hypoxia. The primary outcome was in-hospital mortality. INTERVENTIONS: Exposure to hyperoxia. RESULTS: Over the 5-year period, we identified 554 ventilated patients with acute ischemic stroke (19%), 936 ventilated patients with subarachnoid hemorrhage (32%), and 1,404 ventilated patients with intracerebral hemorrhage (49%) of whom 1,084 (38%) were normoxic, 1,316 (46%) were hypoxic, and 450 (16%) were hyperoxic. Mortality was higher in the hyperoxia group as compared with normoxia (crude odds ratio 1.7 [95% CI 1.3-2.1]; p < 0.0001) and hypoxia groups (crude odds ratio, 1.3 [95% CI, 1.1-1.7]; p < 0.01). In a multivariable analysis adjusted for admission diagnosis, other potential confounders, the probability of being exposed to hyperoxia, and hospital-specific effects, exposure to hyperoxia was independently associated with in-hospital mortality (adjusted odds ratio, 1.2 [95% CI, 1.04-1.5]). CONCLUSION: In ventilated stroke patients admitted to the ICU, arterial hyperoxia was independently associated with in-hospital death as compared with either normoxia or hypoxia. These data underscore the need for studies of controlled reoxygenation in ventilated critically ill stroke populations. In the absence of results from clinical trials, unnecessary oxygen delivery should be avoided in ventilated stroke patients.

RESUMO

OBJECTIVE: In this retrospective multi-centre cohort study, we tested the hypothesis that hyperoxia was not associated with higher in-hospital case fatality in ventilated traumatic brain injury (TBI) patients admitted to the intensive care unit (ICU). METHODS: Admissions of ventilated TBI patients who had arterial blood gases within 24 h of admission to the ICU at 61 US hospitals between 2003 and 2008 were identified. Hyperoxia was defined as PaO2 ≥300 mm Hg (39.99 kPa), hypoxia as any PaO2 <60 mm Hg (7.99 kPa) or PaO2/FiO2 ratio ≤300 and normoxia, not defined as hyperoxia or hypoxia. The primary outcome was in-hospital case fatality. RESULTS: Over the 5-year period, we identified 1212 ventilated TBI patients, of whom 403 (33%) were normoxic, 553 (46%) were hypoxic and 256 (21%) were hyperoxic. The case-fatality was higher in the hypoxia group (224/553 [41%], crude OR 2.3, 95% CI 1.7-3.0, p<.0001) followed by hyperoxia (80/256 [32%], crude OR 1.5, 95% CI 1.1-2.5, p=.01) as compared to normoxia (87/403 [23%]). In a multivariate analysis adjusted for other potential confounders, the probability of being exposed to hyperoxia and hospital-specific characteristics, exposure to hyperoxia was independently associated with higher in-hospital case fatality adjusted OR 1.5, 95% CI 1.02-2.4, p=0.04. CONCLUSIONS: In ventilated TBI patients admitted to the ICU, arterial hyperoxia was independently associated with higher in-hospital case fatality. In the absence of results from clinical trials, unnecessary oxygen delivery should be avoided in critically ill ventilated TBI patients.

RESUMO

PURPOSE: To determine the epidemiology of the acute respiratory distress syndrome (ARDS) and impact on in-hospital mortality in admissions of patients with acute ischemic stroke (AIS) in the United States. METHODS: Retrospective cohort study of admissions with a diagnosis of AIS and ARDS from 1994 to 2008 identified through the Nationwide Inpatient Sample. RESULTS: During the 15-year study period, we found 55 58 091 admissions of patients with AIS. The prevalence of ARDS in admissions of patients with AIS increased from 3% in 1994 to 4% in 2008 (P < .001). The ARDS was more common among younger men, nonwhites, and associated with history of congestive heart failure, hypertension, chronic obstructive pulmonary disease, renal failure, chronic liver disease, systemic tissue plasminogen activator, craniotomy, angioplasty or stent, sepsis, and multiorgan failures. Mortality due to AIS and ARDS decreased from 8% in 1994 to 6% in 2008 (P < .001) and 55% in 1994 to 45% in 2008 (P < .001), respectively. The ARDS in AIS increased in-hospital mortality (odds ratio, 14; 95% confidence interval, 13.5-14.3). A significantly higher length of stay was seen in admissions of patients with AIS having ARDS. CONCLUSION: Our analysis demonstrates that ARDS is rare after AIS. Despite an overall significant reduction in mortality after AIS, ARDS carries a higher risk of death in this patient population.
