RESUMO

PURPOSE: To report on an unusual case of ketamine-precipitated syndrome of inappropriate antidiuretic hormone secretion (SIADH) in an individual managed by an outpatient pain specialty team. CLINICAL FEATURES: A 78-yr-old male presented to the emergency department with lethargy, malaise, nausea, and abdominal bloating three days following intravenous ketamine infusion for intractable postsurgical lumbar radicular pain with neuropathic features. The patient had a history of resected prostate cancer, hyperlipidemia, chronic kidney disease, and spinal stenosis and the cause of his symptoms was investigated. He was found to be hyponatremic and the treating team excluded reversible surgical and medical causes. A Naranjo score of 7 was calculated, suggesting that the correlation between ketamine and hyponatremia was "likely." Hence, a diagnosis of ketamine-precipitated SIADH was made. The patient was treated with fluid restriction and symptoms were controlled with antiemetics. He returned to baseline function with resolution of the hyponatremia within three days of discharge. CONCLUSION: This case is of clinical importance for providers using ketamine in the field of pain management as the effect of this medication reaction can be profound. Clinicians should develop an awareness that ketamine can potentiate adverse effects such as SIADH and they should monitor, detect, and manage as appropriate.


RéSUMé: OBJECTIF: Nous signalons un cas inhabituel de syndrome de sécrétion inappropriée d'hormones antidiurétiques (SIADH - syndrome of inappropriate antidiuretic hormone secretion) précipité par la kétamine chez une personne prise en charge par une équipe spécialisée en douleur en soins ambulatoires. CARACTéRISTIQUES CLINIQUES: Un homme de 78 ans s'est présenté à l'urgence souffrant de léthargie, de malaise, de nausées et de ballonnements abdominaux trois jours après avoir reçu une perfusion intraveineuse de kétamine pour le traitement d'une douleur radiculaire lombaire postopératoire rebelle avec des caractéristiques neuropathiques. Le patient avait des antécédents de résection de cancer de la prostate, d'hyperlipidémie, d'insuffisance rénale chronique et de sténose du canal rachidien, et la cause de ses symptômes a été évaluée. Il s'est avéré hyponatrémique et l'équipe soignante a exclu les causes chirurgicales et médicales réversibles. Un score Naranjo de 7 a été calculé, suggérant que la corrélation entre la kétamine et l'hyponatrémie était « probable ¼. Par conséquent, un diagnostic de SIADH précipité par la kétamine a été posé. Le patient a été traité par restriction hydrique et les symptômes ont été contrôlés par des antiémétiques. Il est revenu à son fonctionnement de référence avec la résolution de l'hyponatrémie dans les trois jours suivant son congé. CONCLUSION: Ce cas est important d'un point de vue clinique pour les praticiens qui utilisent la kétamine pour la prise en charge de la douleur, car l'effet de cette réaction médicamenteuse peut être profond. Les cliniciens devraient prendre conscience que la kétamine peut augmenter des effets indésirables tels que le SIADH et ils devraient monitorer, dépister et prendre en charge le patient, le cas échéant.

RESUMO

INTRODUCTION: The objective of this study was to explore the demographic characteristics, disease specifics and outcomes of adult patients with suspected sepsis presenting to a remote Australian emergency department (ED). A retrospective, uninterrupted time series audit of ED patients presenting with suspected sepsis was conducted. A total of 189 remote presentations were reviewed based on the time of clinician identification of sepsis. METHODS: Retrospective cohort analysis was performed for all adult patients with suspected or confirmed sepsis. RESULTS: A majority of patients presenting with sepsis to a remote hospital were Indigenous (61.9%) with a large proportion (34.9%) presenting by ambulance. Median age was 50 years. Indigenous patients (44.7%, 95%CI 34.1-55.9) were more likely to meet the quick Sequential (sepsis-related) Organ Failure Assessment criteria compared to non-Indigenous patients (27.1% 95%CI 16.6-41.0) (p=0.05 95%CI -1.1-34.3) with higher rates of critical care admission (34.2% v 10.4%) (difference 23.8, p=0.003, 95%CI 7.7-37.5). Congruent with previous research, Indigenous status did not confer a difference in sepsis mortality (12.1% v 11.8%, p=0.91). CONCLUSION: Remote Indigenous patients have worse clinical sepsis scores, are more likely to present by ambulance and require skin and soft tissue source control. This cohort has higher lactate values and critical care requirements but similar mortality rates. Improving access to culturally safe medical care could address this disparity.
