Treating status epilepticus in adults. / Behandling av status epilepticus hos voksne.

This clinical review examines the treatment of status epilepticus, a condition in which epileptic seizures are prolonged and pose a significant risk of brain damage and death. International guidelines recommend the use of benzodiazepines as first-line treatment, and these should be administered promptly and in appropriate doses. Second-line treatment involves the use of high-dose anti-seizure medications to stop and prevent seizures. If seizure activity persists, general anaesthesia should be administered as soon as possible. All neurological hospital departments should have established and rehearsed protocols for treating status epilepticus.

Citizen attitudes to non-treatment decision making: a Norwegian survey.

BACKGROUND: Decisions about appropriate treatment at the end of life are common in modern healthcare. Non-treatment decisions (NTDs), comprising both withdrawal and withholding of (potentially) life-prolonging treatment are in principle accepted in Norway. However, in practice they may give rise to significant moral problems for health professionals, patients and next of kin. Here, patient values must be considered. It is relevant to study the moral views and intuitions of the general population on NTDs and special areas of contention such as the role of next of kin in decision-making. METHODS: Electronic survey to members of a nationally representative panel of Norwegian adults. Respondents were presented with vignettes describing patients with disorders of consciousness, dementia, and cancer where patient preferences varied. Respondents answered ten questions about the acceptability of non-treatment decision making and the role of next of kin. RESULTS: We received 1035 complete responses (response rate 40.7%). A large majority, 88%, supported the right of competent patients to refuse treatment in general. When an NTD was in line with the patient's previously expressed preferences, more respondents tended to find NTDs acceptable. More respondents would accept NTDs for themselves than for the vignette patients. In a scenario with an incompetent patient, clear majorities wanted the views of next of kin to be given some but not decisive weight, and more weight if concordant with the patient's wishes. There were, however, large variations in the respondents' views. CONCLUSION: This survey of a representative sample of the Norwegian adult population indicates that attitudes to NTDs are often in line with national laws and guidelines. However, the high variance among the respondents and relatively large weight given to next of kin's views, indicate a need for appropriate dialogue among all stakeholders to prevent conflicts and extra burdens. Furthermore, the emphasis given to previously expressed opinions indicates that advance care planning may increase the legitimacy of NTDs and prevent challenging decision-making processes.

The Norwegian Medical Association should continue to oppose assisted dying. / Legeforeningen bør fortsatt si nei til dødshjelp.

The Norwegian Medical Association has long taken a clear stance against the legalisation of assisted dying. Recently, the British Medical Association moved to a neutral stance. Is it now time for the Norwegian Medical Association to change its course?

Brain monitoring in hospitals needs to be strengthened. / Hjerneovervåking i sykehusene må styrkes.

Careful brain monitoring saves lives and is beneficial to patients' health. Nevertheless, Norway lacks guidelines for brain monitoring in hospitals.

Influence of valproate-induced hyperammonemia on treatment decision in an adult status epilepticus cohort.

INTRODUCTION: Status epilepticus (SE) is a neurological emergency in which immediate intervention is required to prevent permanent brain damage and death. Intravenous (IV) valproic acid (VPA) is often used for the treatment of SE. However, IV VPA frequently increases the blood ammonia level. In this study, we explore the impact of IV VPA-induced hyperammonemia (HA) on treatment management of SE and discuss the challenges related to this particular condition. METHODS: We used data from medical records of 31 adult patients (≥18 years) treated with IV VPA for SE at Oslo University Hospital between January 2006 and October 2019. Clinical and blood sample data and information about the influence of HA on treatment were collected. Correlations between ammonia levels and other continuous or categorical variables were tested using the Pearson's correlation coefficient. The Kruskal-Wallis H-test was used to analyze associations between different variables and treatment decisions. RESULTS: Thirty of 31 patients had increased ammonia level during IV VPA treatment. In 16/30 patients, VPA was discontinued, and in 6/30 patients, the dose was reduced. We found a difference in the median peak ammonia level among the groups where VPA was discontinued (99 µmol/l), reduced (71 µmol/l), and continued (55.5 µmol/l) (P = 0.008). Also clinical status, measured by West Haven Criteria, varied among the groups where VPA was discontinued (3.5), reduced (2.5), and continued (2.0) (P = 0.01). Treatment decisions at peak ammonia were not associated with the level of liver enzymes and bilirubin. CONCLUSION: Hyperammonemia had a substantial impact on further management. To date, no recommendations exist on how to manage VPA-induced HA in SE. We call for systematic prospective studies and evidence-based guidelines.

Posterior circulation stroke diagnosis using HINTS in patients presenting with acute vestibular syndrome: A systematic review.

PURPOSE: Acute vestibular syndrome - vertigo, nausea/vomiting, nystagmus and gait unsteadiness - is common, and differentiating posterior circulation stroke from a peripheral cause can be challenging. The National Institute of Health Stroke Scale (NIHSS) does not include acute vestibular syndrome, and early computed tomography scanning cannot rule out acute ischaemia. A positive Head Impulse-Nystagmus-Test of Skew (HINTS) test suggests posterior circulation stroke in acute vestibular syndrome when any of three signs are present: normal horizontal head impulse, gaze-direction nystagmus or eye skew deviation. This systematic review examined the accuracy of positive HINTS in identifying posterior circulation stroke in acute vestibular syndrome patients. METHODS: We searched MEDLINE (1966 to 21 December 2017), EMBASE (1980 to December 2017), Web of Science and scanned bibliographies. Two authors independently screened relevant articles and extracted data. We included studies where HINTS was used to identify posterior circulation stroke with diagnosis confirmed using magnetic resonance imaging. FINDINGS: Six studies (n = 644 patients) were identified. Acute stroke was confirmed in 200 (31.1%) patients. There was a 15-fold increased risk of posterior circulation stroke in patients with positive HINTS test compared to those with no abnormality (RR: 15.84, 95% CI: 5.25-47.79). For any stroke, the pooled sensitivity was 95.5% (95% CI: 92.6-98.4%) and specificity was 71.2% (95% CI: 67.0-75.4%). DISCUSSION AND CONCLUSION: The data suggest that the HINTS test as one element of clinical evaluation is useful to differentiate posterior circulation stroke from peripheral causes in acute vestibular syndrome. Further studies are needed to validate HINTS as a clinical prediction tool in emergency department settings and selection of patients for reperfusion treatment.

Ethical challenges in tracheostomy-assisted ventilation in amyotrophic lateral sclerosis.

The special nature of amyotrophic lateral sclerosis (ALS) and tracheostomy with invasive ventilation (TIV) leads to challenges that can be difficult in two senses: not only to handle well, but also to discuss with patients and other involved stakeholders. Because of the delicate nature of interpersonal relations and communication in ALS, some of the downsides to TIV may almost take on a nature of taboo, making them difficult to raise for open discussion. Yet these ethical challenges are important to be aware of, not only for health professionals and managers but, arguably, also for patients and next of kin. They are important also for a wider professional and societal debate about whether and to whom TIV should be offered. In this paper we highlight and examine ethical challenges in TIV for ALS, with a special emphasis on those that are hard to discuss openly and that therefore might fail to be addressed. The analysis is structured by the four core principles of healthcare ethics: beneficence, nonmaleficence, respect for patient autonomy, and justice.
