RESUMO
Background: Intracerebral hemorrhage (ICH) still poses a substantial challenge in clinical medicine because of the high morbidity and mortality rate that characterizes it. This review article expands into the complex pathophysiological processes underlying primary and secondary neuronal death following ICH. It explores the potential of therapeutic hypothermia as an intervention to mitigate these devastating effects. Methods: A comprehensive literature review to gather relevant studies published between 2000 and 2023. Discussion: Primary brain injury results from mechanical damage caused by the hematoma, leading to increased intracranial pressure and subsequent structural disruption. Secondary brain injury encompasses a cascade of events, including inflammation, oxidative stress, blood-brain barrier breakdown, cytotoxicity, and neuronal death. Initial surgical trials failed to demonstrate significant benefits, prompting a shift toward molecular mechanisms driving secondary brain injury as potential therapeutic targets. With promising preclinical outcomes, hypothermia has garnered attention, but clinical trials have yet to establish its definitive effectiveness. Localized hypothermia strategies are gaining interest due to their potential to minimize systemic complications and improve outcomes. Ongoing and forthcoming clinical trials seek to clarify the role of hypothermia in ICH management. Conclusion: Therapeutic hypothermia offers a potential avenue for intervention by targeting the secondary injury mechanisms. The ongoing pursuit of optimized cooling protocols, localized cooling strategies, and rigorous clinical trials is crucial to unlocking the potential of hypothermia as a therapeutic tool for managing ICH and improving patient outcomes.
RESUMO
Objective: To determine the clinical and financial feasibility of implementing a poc-EEG system in a community hospital. Design: Data from a prospective cohort displaying abnormal mentation concerning for NCSE or rhythmic movements due to potential underlying seizure necessitating EEG was collected and compared to a control group containing patient data from 2020. Setting: A teaching community hospital with limited EEG support. Patients: The study group consisted of patients requiring emergent EEG during hours when conventional EEG was unavailable. Control group is made up of patients who were emergently transferred for EEG during the historical period. Interventions: Application and interpretation of Ceribell®, a poc-EEG system. Measurement and main results: 88 patients were eligible with indications for poc-EEG including hyperkinetic movements post-cardiac arrest (19%), abnormal mentation after possible seizure (46%), and unresponsive patients with concern for NCSE (35%). 21% had seizure burden on poc-EEG and 4.5% had seizure activity on follow-up EEG. A mean of 1.1 patients per month required transfer to a tertiary care center for continuous EEG. For the control period, a total of 22 patients or a mean of 2 patients per month were transferred for emergent EEG. Annually, we observed a decrease in the number of transferred patients in the post-implementation period by 10.8 (95% CI: -2.17-23.64, p = 0.1). Financial analysis of the control found the hospital system incurred a loss of $3,463.11 per patient transferred for an annual loss of $83,114.64. In the study group, this would compute to an annual loss of $45,713.05 for an overall decrease in amount lost of $37,401.59. We compared amount lost per patient between historical controls and study patients. Implementation of poc-EEG resulted in an overall decrease in annual amount lost of $37,401.59 by avoidance of transfer fees. We calculated the amount gained per patient in the study group to be $13,936.44. To cover the cost of the poc-EEG system, 8.59 patients would need to avoid transfer annually. Conclusion: A poc-EEG system can be safely implemented in a community hospital leading to an absolute decrease in transfers to tertiary hospital. This decrease in patient transfers can cover the cost of implementing the poc-EEG system. The additional benefits from transfer avoidance include clinical benefits such as rapid appropriate treatment of seizures and avoidance of unnecessary treatment as well as negating transfer risk and keeping the patient at their local hospital.
RESUMO
BACKGROUND AND PURPOSE: Computed tomography angiography and perfusion studies have increasingly become a part of acute stroke evaluation. However, the volume, benefit, and scope of need for imaging is sometimes debated. PURPOSE: This study evaluated the safety, efficiency, and efficacy of changes to the acute stroke evaluation protocol at our academic institution. Previously, contrast-enhanced imaging was "opt-in" and ordered upon suspicion of large vessel occlusion. This was subsequently transitioned to one where contrast-enhanced imaging was automatically ordered for all patients with "opt-out" of imaging if felt appropriate. METHODS: We performed a retrospective, case-control study that included patients evaluated for acute stroke management before and after the protocol change. Six hundred forty-seven patients met criteria for study involvement, of which 258 were in the preprotocol and 389 in the postprotocol group. RESULTS: There was no significant difference in rate of acute kidney injury and no delay in door-to-needle time. There was significant improvement in door-to-groin puncture times (49.9 minutes) for typical cases and increase in monthly rate of endovascular therapy (EVT). CONCLUSION: Protocolization of contrast-enhanced imaging for acute stroke evaluation proved safe with respect to renal function, did not delay door-to-needle time, improved door-to-groin puncture time, and lead to higher rates of EVT.

Background and purpose: Therapeutic hypothermia (TH), or targeted temperature management (TTM), is a classic treatment option for reducing inflammation and potentially other destructive processes across a wide range of pathologies, and has been successfully used in numerous disease states. The ability for TH to improve neurological outcomes seems promising for inflammatory injuries but has yet to demonstrate clinical benefit in the intracerebral hemorrhage (ICH) patient population. Minimally invasive ICH evacuation also presents a promising option for ICH treatment with strong preclinical data but has yet to demonstrate functional improvement in large randomized trials. The biochemical mechanisms of action of ICH evacuation and TH appear to be synergistic, and thus combining hematoma evacuation with cooling therapy could provide synergistic benefits. The purpose of this working group was to develop consensus recommendations on optimal clinical trial design and outcomes for the use of therapeutic hypothermia in ICH in conjunction with minimally invasive ICH evacuation. Methods: An international panel of experts on the intersection of critical-care TH and ICH was convened to analyze available evidence and form a consensus on critical elements of a focal cooling protocol and clinical trial design. Three focused sessions and three full-group meetings were held virtually from December 2020 to February 2021. Each meeting focused on a specific subtopic, allowing for guided, open discussion. Results: These recommendations detail key elements of a clinical cooling protocol and an outline for the roll-out of clinical trials to test and validate the use of TH in conjunction with hematoma evacuation as well as late-stage protocols to improve the cooling approach. The combined use of systemic normothermia and localized moderate (33.5°C) hypothermia was identified as the most promising treatment strategy. Conclusions: These recommendations provide a general outline for the use of TH after minimally invasive ICH evacuation. More research is needed to further refine the use and combination of these promising treatment paradigms for this patient population.
RESUMO
BACKGROUND: Intracerebral hemorrhage remains the deadliest form of stroke worldwide, inducing neuronal death through a wide variety of pathways. Therapeutic hypothermia is a robust and well-studied neuroprotectant widely used across a variety of specialties. AIMS: This review summarizes results from preclinical and clinical studies to highlight the overall effectiveness of therapeutic hypothermia to improve long-term intracerebral hemorrhage outcomes while also elucidating optimal protocol regimens to maximize therapeutic effect. SUMMARY OF REVIEW: A systematic review was conducted across three databases to identify trials investigating the use of therapeutic hypothermia to treat intracerebral hemorrhage. A random-effects meta-analysis was conducted on preclinical studies, looking at neurobehavioral outcomes, blood brain barrier breakdown, cerebral edema, hematoma volume, and tissue loss. Several mixed-methods meta-regression models were also performed to adjust for variance and variations in hypothermia induction procedures. Twwenty-one preclinical studies and five human studies were identified. The meta-analysis of preclinical studies demonstrated a significant benefit in behavioral scores (ES = -0.43, p = 0.02), cerebral edema (ES = 1.32, p = 0.0001), and blood brain barrier (ES = 2.73, p ≤ 0.00001). Therapeutic hypothermia was not found to significantly affect hematoma expansion (ES = -0.24, p = 0.12) or tissue loss (ES = 0.06, p = 0.68). Clinical study outcome reporting was heterogeneous; however, there was recurring evidence of therapeutic hypothermia-induced edema reduction. CONCLUSIONS: The combined preclinical evidence demonstrates that therapeutic hypothermia reduced multiple cell death mechanisms initiated by intracerebral hemorrhage; yet, there is no definitive evidence in clinical studies. The cooling strategies employed in both preclinical and clinical studies were highly diverse, and focused refinement of cooling protocols should be developed in future preclinical studies. The current data for therapeutic hypothermia in intracerebral hemorrhage remains questionable despite the highly promising indications in preclinical studies. Definitive randomized controlled studies are still required to answer this therapeutic question.

OBJECTIVES: We aim to determine the incidence of decompressive hemicraniectomy (DHC) in the modern era of mechanical thrombectomy techniques and improved revascularization outcomes. METHODS: We performed a retrospective analysis of 512 patients admitted with acute ischemic strokes with anterior circulation large-vessel occlusion that were treated by mechanical thrombectomy from 2010-2019. The primary endpoint was the need for surgical decompression. Secondary endpoints were infarct size, hemorrhagic conversion, and functional outcome at hospital discharge. RESULTS: Of the 512 patients, 18 (3.5%) underwent DHC at a median 2.0 days from stroke onset. The DHC group was significantly younger than the non-DHC group (P < 0.001), had worse reperfusion rates (P = 0.024) and larger infarct size (P < 0.001). Hemorrhagic conversion was more frequent in the DHC group but did not reach statistical significance (P = 0.08). From 2010-2015, 196 patients underwent a mechanical thrombectomy, 13 of whom (6.6%) required a DHC, while 316 patients underwent mechanical thrombectomy from 2016-2019 and only 5 patients required a DHC (1.6%; P = 0.002). Younger age (P < 0.001), urinary tract infection (P < 0.001) and increasing infarct size were significantly associated with needing a DHC. When controlling for other risk factors, higher thrombolysis in cerebral infarction score significantly reduced the need for decompressive hemicraniectomy (P = 0.004). CONCLUSIONS: This is one of the largest single-center experiences demonstrating that improved recanalization decreased the need for DHC without increasing the risk of hemorrhagic conversion.

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.

BACKGROUND: Data suggest that elderly patients have less favorable outcomes after ischemic stroke. OBJECTIVE: To study the outcomes after intravenous tissue plasminogen activator (tPA) administration in elderly patients with acute ischemic stroke. METHODS: Cross-sectional study using prospective collected patient data maintained via our "tele-stroke" network, which provides acute care in 29 community hospitals within our region from 2013-2015. Exposure of interest was age divided into >80 years (octogenarian) or younger. Outcomes of interest were rate of intravenous tPA administration, hemorrhagic transformation (ICH), in-hospital neurological deterioration, and poor outcome defined as a composite of hospital discharge to long-term care facility or death. RESULTS: Mean age 67 ± 16 years, 57 % (743/1317) were women, and median (Md) NIHSS was 4 (Interquartile Range [IQR] 8). The rate of tPA was 20 % (267/1317). Compared to reported rates of tPA administration in the nation, our tPA rate exceeded the one from the literature (20 % v 3%, z = 2.83, SE = 0.04, p = .005). There were no differences in ICH or neurological deterioration. The octogenarian group had a higher proportion of poor-outcome (61 % vs. 23 %, p < 0.001) than the younger group but similar in-hospital case-fatality (25 % v 14 %, p = 0.09). Predictors of poor-outcome were age >80 (OR 4.9; CI, 2.0-12, p < .001) and α-NIHSS>9. (OR 8.7; CI, 3.5-20, p < .001). CONCLUSION: Our data suggest that in our "tele-stroke" network, rates of tPA administration are higher than those reported in the literature and that this rate was not different in octogenarians compared to younger patients. Octogenarians were not at risk for ICH or neurological deterioration after tPA administration. However, octogenarians had a higher risk of poor outcome.

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.

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.

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?

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.

As more specialized care gets centralized in centers of excellence, patients admitted to rural hospitals may be at a disadvantage at the time of accessing expertise or receiving advanced care. In this setting, telemedicine models provide a justification to equalize care across different levels. The diversity in telemedicine services is vast and is expanding. Even with all the subsets of telemedicine, including telepharmacy, telestroke, teledialysis, and tele-emergency medicine, the reasons for providing services and associated limitations are similar. However, there is a lack of empirical research including best practices and resultant outcomes for these subsets of telemedicine models.

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.

INTRODUCTION: Acute ischemic stroke (AIS) is the fourth leading cause of death in the US. Numerous studies have demonstrated the use of comprehensive stroke units and neurological intensive care units (NICU) in improving outcomes after stroke. We hypothesized that an expanded neurocritical care (NCC) service would decrease resource utilization in patients with LHI. METHODS: Retrospective data from consecutive admissions of large hemispheric infarction (LHI) patients requiring mechanical ventilation were acquired from the hospital medical records. Between 2011-2013, there were 187 consecutive patients admitted to the Jefferson Hospital for Neuroscience (Philadelphia, USA) with AIS and acute respiratory failure. Our intention was to determine the number of tracheostomies done over time. The primary outcome measure was the number of tracheostomies over time. Secondary outcomes were, ventilator-free days (Vfd), total hospital charges, intensive care unit length of stay (ICU-LOS), and total hospital length of stay (hospital-LOS), including ICU LOS. Hospital charges were log-transformed to meet assumptions of normality and homoscedasticity of residual variance terms. Generalized Linear Models were used and ORs and 95% CIs calculated. The significance level was set at α = 0.05. RESULTS: Of the 73 patients included in this analysis, 33% required a tracheostomy. There was a decrease in the number of tracheostomies undertaken since 2011. (OR 0.8; 95% CI 0.6-0.9: p=0.02).Lower Vfd were seen in tracheostomized patients (OR 0.11; 95%CI 0.1-0.26: p<0.0001). The log-hospital charges decreased over time but not significantly (OR 0.9; 95%CI 0.78-1.07: p=0.2) and (OR 0.99; 95%CI 0.85-1.16: p=0.8) from 2012 to 2013 respectively.The ICU-LOS at 23 days vs 10 days (p=0.01) and hospital-LOS at 33 days vs 11 days (p=0.008) were higher in tracheostomized patients. CONCLUSION: The data suggest that in LHI-patients requiring mechanical ventilation, a dedicated NCC service reduces the overall need for tracheostomy, increases Vfd, and decreases ICU and hospital-LOS.
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.

Evidence from animal models indicates that lowering temperature by a few degrees can produce substantial neuroprotection. In humans, hypothermia has been found to be neuroprotective with a significant impact on mortality and long-term functional outcome only in cardiac arrest and neonatal hypoxic-ischemic encephalopathy. Clinical trials have explored the potential role of maintaining normothermia and treating fever in critically ill brain injured patients. This review concentrates on basic concepts to understand the physiologic interactions of thermoregulation, effects of thermal modulation in critically ill patients, proposed mechanisms of action of temperature modulation, and practical aspects of targeted temperature management.

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.
