First-Response ABCDE Management of Status Epilepticus: A Prospective High-Fidelity Simulation Study

Respiratory infections following status epilepticus (SE) are frequent, and associated with higher mortality, prolonged ICU stay, and higher rates of refractory SE. Lack of airway protection may contribute to respiratory infectious complications. This study investigates the order and frequency of physicians treating a simulated SE following a systematic Airways-Breathing-Circulation-Disability-Exposure (ABCDE) approach, identifies risk factors for non-adherence, and analyzes the compliance of an ABCDE guided approach to SE with current guidelines. We conducted a prospective single-blinded high-fidelity trial at a Swiss academic simulator training center. Physicians of different affiliations were confronted with a simulated SE. Physicians (; n; = 74) recognized SE and performed a median of four of the five ABCDE checks (interquartile range 3-4). Thereof, 5% performed a complete assessment. Airways were checked within the recommended timeframe in 46%, breathing in 66%, circulation in 92%, and disability in 96%. Head-to-toe (exposure) examination was performed in 15%. Airways were protected in a timely manner in 14%, oxygen supplied in 69%, and antiseizure drugs (ASDs) administered in 99%. Participants' neurologic affiliation was associated with performance of fewer checks (regression coefficient -0.49;; p; = 0.015). We conclude that adherence to the ABCDE approach in a simulated SE was infrequent, but, if followed, resulted in adherence to treatment steps and more frequent protection of airways

Pitfalls in the Diagnosis and Management of Invasive Pneumococcal Meningoencephalitis - What We Can Learn From a Case

Invasive pneumococcal meningitis is a life-threatening infectious disease affecting the central nervous system. It continues to be the most common type of community-acquired acute bacterial meningitides. Despite advances in neuro-critical care, the case fatality rate remains high. Rapid diagnosis and initiation of antibiotic therapy precludes mortality and long-term neurological sequelae in survivors. However, not all cases are easily recognised, and unanticipated complications may impede optimal course and outcome. Here, we describe a case of invasive pneumococcal meningoencephalitis in a 65-year-old man with an unusual initial presentation and pitfalls in the course of the disease. We highlight the importance of early diagnosis and treatment as well as recognition and management of complications

What to exclude when brain death is suspected

With advances in critical care and organ donation, diagnosis of brain death is gaining importance. We aimed to assess potential brain death confounders from the literature, elucidating clinical presentation and diagnostic approaches in these cases.; PubMed and Embase were screened using 37 predefined search terms to identify suitable articles reporting cases, case series, or cohort studies in adults.; Out of 4769 articles, 40 case reports or case series describing 45 patients with 19 critical conditions were identified. Mortality was 11% and full recovery 33%. Intoxications (42%; mainly anti-seizure drugs and baclofen) and polyneuritis (37%) were most frequent. Brainstem reflex tests were reported in 96%, apnoea test in 16% and ancillary tests in all but one patient. Full recovery mainly occurred with intoxications. Quality of evidence regarding frequency of confounders is very low and risk of bias high.; Brain death confounders are infrequently reported and formal studies are lacking. Mainly younger patients with polyneuritis and intoxications are described. As outcome, especially in the latter, is often favourable, high awareness and strict adherence to guidelines is crucial. The importance of identifying pathologies compatible with extensive and irreversible brain damage before proceeding to diagnostic tests should be emphasized

Procedures of brain death diagnosis and organ explantation in a tertiary medical centre – a retrospective eight-year cohort study

AIMS OF THE STUDY: To assess the frequency and variables associated with the need for ancillary tests to confirm suspected brain death in adult patients, and to assess the time from brain death to organ explantation in donors. We further sought to identify modifiable factors influencing the time between brain death and start of surgery. METHODS: Medical records and the Swiss organ allocation system registry were screened for all consecutive adult patients diagnosed with brain death at an intensive care unit of a Swiss tertiary medical centre from 2013 to 2020. The frequency and variables associated with the performance of ancillary tests (i.e., transcranial doppler, digital subtraction angiography, and computed tomography angiography) to confirm brain death were primary outcomes; the time from death to organ explantation as well as modifying factors were defined as secondary outcomes. RESULTS: Among 91 patients with a diagnosis of brain death, 15 were not explanted and did not undergo further ancillary tests. Of the remaining 76 patients, who became organ donors after brain death, ancillary tests were performed in 24%, most frequently in patients with hypoxic-ischaemic encephalopathy. The leading presumed causes of death (not mutually exclusive) were haemorrhagic strokes (49%), hypoxic-ischaemic encephalopathies (33%) and severe traumatic brain injuries (22%). Surgery for organ explantation was started within a median of 16 hours (interquartile range [IQR] 13–18) after death with delay increasing over time (nonparametric test for trend p = 0.05), mainly due to organ allocation procedures. Patients with brain death confirmed during night shifts were explanted earlier (during night shifts 14.3 hours, IQR 11.8–16.8 vs 16.3 hours, IQR 13.5–18.5 during day shifts; p = 0.05). CONCLUSIONS: Ancillary tests to confirm brain death are frequently performed, mainly in resuscitated patients. The delay to surgery for organ explantation after confirmed brain death was longer during day shifts, increased over time and was mainly determined by organ allocation procedures. The trial was registered on clinical trials.gov (identifier: NCT03984981

Acute Hemorrhagic Leukoencephalitis: A Case and Systematic Review of the Literature

Objectives:; To present a patient with acute hemorrhagic leukoencephalitis (AHLE) and a systematic review of the literature analyzing diagnostic procedures, treatment, and outcomes of AHLE.; Methods:; PubMed and Cochrane databases were screened. Papers published since 01/01/2000 describing adult patients are reported according to the PRISMA-guidelines.; Results:; A 59-year old male with rapidly developing coma and cerebral biopsy changes compatible with AHLE is presented followed by 43 case reports from the literature including males in 67% and a mean age of 38 years. Mortality was 47%. Infectious pathogens were reported in 35%, preexisting autoimmune diseases were identified in 12%. Neuroimaging revealed uni- or bihemispheric lesions in 65% and isolated lesions of the cerebellum, pons, medulla oblongata or the spinal cord without concomitant hemispheric involvement in 16%. Analysis of the cerebrospinal fluid showed an increased protein level in 87%, elevated white blood cells in 65%, and erythrocytes in 39%. Histology (reported in 58%) supported the diagnosis of AHLE in all cases. Glucocorticoids were used most commonly (97%), followed by plasmapheresis (26%), and intravenous immunoglobulins (12%), without a clear temporal relationship between treatment and the patients' clinical course.; Conclusions:; Although mortality was lower than previously reported, AHLE remains a life-threatening neurologic emergency with high mortality. Diagnosis is challenging as the level of evidence regarding the diagnostic yield of clinical, neuroimaging and laboratory characteristics remains low. Hence, clinicians are urged to heighten their awareness and to prompt cerebral biopsies in the context of rapidly progressive neurologic decline of unknown origin with the concurrence of the compiled characteristics. Future studies need to focus on treatment characteristics and their effects on course and outcome

Early timing of anesthesia in status epilepticus is associated with complete recovery : A 7‐year retrospective two‐center study

Objective This study was undertaken to investigate the efficacy, tolerability, and outcome of different timing of anesthesia in adult patients with status epilepticus (SE). Methods Patients with anesthesia for SE from 2015 to 2021 at two Swiss academic medical centers were categorized as anesthetized as recommended third‐line treatment, earlier (as first‐ or second‐line treatment), and delayed (later as third‐line treatment). Associations between timing of anesthesia and in‐hospital outcomes were estimated by logistic regression. Results Of 762 patients, 246 received anesthesia; 21% were anesthetized as recommended, 55% earlier, and 24% delayed. Propofol was preferably used for earlier (86% vs. 55.5% for recommended/delayed anesthesia) and midazolam for later anesthesia (17.2% vs. 15.9% for earlier anesthesia). Earlier anesthesia was statistically significantly associated with fewer infections (17% vs. 32.7%), shorter median SE duration (.5 vs. 1.5 days), and more returns to premorbid neurologic function (52.9% vs. 35.5%). Multivariable analyses revealed decreasing odds for return to premorbid function with every additional nonanesthetic antiseizure medication given prior to anesthesia (odds ratio [OR] = .71, 95% confidence interval [CI] = .53–.94) independent of confounders. Subgroup analyses revealed decreased odds for return to premorbid function with increasing delay of anesthesia independent of the Status Epilepticus Severity Score (STESS; STESS = 1‐2: OR = .45, 95% CI = .27–.74; STESS &gt; 2: OR = .53, 95% CI = .34–.85), especially in patients without potentially fatal etiology (OR = .5, 95% CI = .35–.73) and in patients experiencing motor symptoms (OR = .67, 95% CI = .48–.93). Significance In this SE cohort, anesthetics were administered as recommended third‐line therapy in only every fifth patient and earlier in every second. Increasing delay of anesthesia was associated with decreased odds for return to premorbid function, especially in patients with motor symptoms and no potentially fatal etiology.</p

Sex-related differences in adult patients with status epilepticus : a seven-year two-center observation

Background Conflicting findings exist regarding the influence of sex on the development, treatment, course, and outcome of status epilepticus (SE). Our study aimed to investigate sex-related disparities in adult SE patients, focusing on treatment, disease course, and outcome at two Swiss academic medical centers. Methods In this retrospective study, patients treated for SE at two Swiss academic care centers from Basel and Geneva from 2015 to 2021 were included. Primary outcomes were return to premorbid neurologic function, death during hospital stay and at 30 days. Secondary outcomes included characteristics of treatment and disease course. Associations with primary and secondary outcomes were assessed using multivariable logistic regression. Analysis using propensity score matching was performed to account for the imbalances regarding age between men and women. Results Among 762 SE patients, 45.9% were women. No sex-related differences were found between men and women, except for older age and lower frequency of intracranial hemorrhages in women. Compared to men, women had a higher median age (70 vs. 66, p = 0.003), had focal nonconvulsive SE without coma more (34.9% vs. 25.5%; p = 0.005) and SE with motor symptoms less often (52.3% vs. 63.6%, p = 0.002). With longer SE duration (1 day vs. 0.5 days, p = 0.011) and a similar proportion of refractory SE compared to men (36.9% vs. 36.4%, p = 0.898), women were anesthetized and mechanically ventilated less often (30.6% vs. 42%, p = 0.001). Age was associated with all primary outcomes in the unmatched multivariable analyses, but not female sex. In contrast, propensity score-matched multivariable analyses revealed decreased odds for return to premorbid neurologic function for women independent of potential confounders. At hospital discharge, women were sent home less (29.7% vs. 43.7%, p &lt; 0.001) and to nursing homes more often (17.1% vs. 10.0%, p = 0.004). Conclusions This study identified sex-related disparities in the clinical features, treatment modalities, and outcome of adult patients with SE with women being at a disadvantage, implying that sex-based factors must be considered when formulating strategies for managing SE and forecasting outcomes.</p
