For the avoidance of doubt, the Licensor may also offer the Licensed Material under separate terms or conditions or stop distributing the Licensed Material at any time; however, doing so will not terminate this Public License.

Abstract
Objectives: There is insufficient data on frequency of electrolyte imbalance in patients with acute stroke from developing countries in sub-Saharan Africa. This study aimed to ascertain the frequency and pattern of electrolyte imbalance, associated risk factors and outcome among patients with acute stroke in a tertiary hospital in Nigeria.
Methods: A total of 134 patients who presented within 7 days of a brain neuroimaging confirmed acute stroke event and met the criteria for inclusion were enrolled for this study. Electrolytes were analysed and the patients were followed up for I month.
Results: A large proportion (88.8%) of the patients had at least one electrolyte abnormality. The commonest electrolyte derangements were hypokalaemia (41.1%) and hyponatraemia (38.1%). Although not statistically significant, electrolyte imbalance occurred more frequently in younger patients (p = 0.770), males (p = 0.258), those with left hemispheric strokes (p = 0.307), and ischaemic strokes (p = 0.069). The fatality rate was 20.1% and was higher in those with electrolyte imbalance.
Conclusion: Electrolyte imbalance is a common feature in acute stroke patients. It should be investigated for early intervention and correction.
Objectifs: Il n' y a pas de données suffisantes sur la fréquence du déséquilibre électrolytique des patients avec un accident vasculaire cérébral aigu des pays en voie de développement en Afrique subsaharienne. Le but de cette étude est de vérifier la fréquence et le modèle du déséquilibre électrolytique, des facteurs de risque associés et le résultat parmi les patients avec un accident vasculaire cérébral dans un hôpital tertiaire au Nigéria.
Méthodes: Un total de 134 patients qui ont présenté dans 7 jours de neuroimagerie ont confirmé l'événement d'accident vasculaire cérébral et qui ont répondu aux critères d'inclusion sont enrôlés pour cette étude. Les électrolytes ont été analysées et les patients ont été suivis pendant 1 mois.
Résultats: Une grande proportion (88,8％) des patients avaient au moins une anomalie électrolytique. La plus fréquente des dérangements électrolytiques étaient l'hypokaliémie(41,1％) et l'hyponatrémie(38,1％). Bien que, ce n'est pas statistiquement significatif, le déséquilibre électrolytique s'est présenté chez des patients les plus jeunes (p=0,770), mâles (p=0,258), les personnes ayant un accident vasculaire cérébral de l'hémisphère gauche (p=0,307), et un accident vasculaire cérébral ishémique (p=0,069). Le taux de mortalité était 20,1％et c'était plus élevé chez les personnes présentant un déséquilibre électrolytique.
Conclusion: Le déséquilibre électrolytique est un trait commun des patients ayant AVC. Il devrait être examiner pour une intervention précoce et correction.
