RESUMEN
PURPOSE: We aimed to investigate the association between initial dysnatremia (hyponatremia and hypernatremia) and in-hospital mortality, as well as between initial dysnatremia and functional outcomes, among children with traumatic brain injury (TBI). METHOD: We performed a multicenter observational study among 26 pediatric intensive care units from January 2014 to August 2022. We recruited children with TBI under 18 years of age who presented to participating sites within 24 h of injury. We compared demographics and clinical characteristics between children with initial hyponatremia and eu-natremia and between those with initial hypernatremia and eu-natremia. We defined poor functional outcome as a discharge Pediatric Cerebral Performance Category (PCPC) score of moderate, severe disability, coma, and death, or an increase of at least 2 categories from baseline. We performed multivariable logistic regression for mortality and poor PCPC outcome. RESULTS: Among 648 children, 84 (13.0%) and 42 (6.5%) presented with hyponatremia and hypernatremia, respectively. We observed fewer 14-day ventilation-free days between those with initial hyponatremia [7.0 (interquartile range (IQR) = 0.0-11.0)] and initial hypernatremia [0.0 (IQR = 0.0-10.0)], compared to eu-natremia [9.0 (IQR = 4.0-12.0); p = 0.006 and p < 0.001]. We observed fewer 14-day ICU-free days between those with initial hyponatremia [3.0 (IQR = 0.0-9.0)] and initial hypernatremia [0.0 (IQR = 0.0-3.0)], compared to eu-natremia [7.0 (IQR = 0.0-11.0); p = 0.006 and p < 0.001]. After adjusting for age, severity, and sex, presenting hyponatremia was associated with in-hospital mortality [adjusted odds ratio (aOR) = 2.47, 95% confidence interval (CI) = 1.31-4.66, p = 0.005] and poor outcome (aOR = 1.67, 95% CI = 1.01-2.76, p = 0.045). After adjustment, initial hypernatremia was associated with mortality (aOR = 5.91, 95% CI = 2.85-12.25, p < 0.001) and poor outcome (aOR = 3.00, 95% CI = 1.50-5.98, p = 0.002). CONCLUSION: Among children with TBI, presenting dysnatremia was associated with in-hospital mortality and poor functional outcome, particularly hypernatremia. Future research should investigate longitudinal sodium measurements in pediatric TBI and their association with clinical outcomes.

OBJECTIVE: There is a paucity of information on pediatric traumatic brain injury (TBI) care in Asia and Latin America. In this study, the authors aimed to describe the clinical practices of emergency departments (EDs) participating in the Saline in Asia and Latin-America Neurotrauma in the Young (SALTY) study, by comparing designated trauma centers (DTCs) and nontrauma centers (NTCs) in their networks. METHODS: The authors performed a site survey study on pediatric TBI management in the EDs in 14 countries. Two European centers joined other participating sites in Asia and Latin America. Questions were formulated after a critical review of current TBI guidelines and published surveys. The authors performed a descriptive analysis and stratified centers based on DTC status. RESULTS: Of 24 responding centers (70.6%), 50.0% were DTCs, 70.8% had academic affiliations, and all centers were in urban settings. Patients were predominantly transferred to DTCs by centralized prehospital services compared to those sent to NTCs (83.3% vs 41.7%, p = 0.035). More NTCs received a majority of their patients directly from the trauma scene compared to DTCs (66.7% vs 25.0%, p = 0.041). Ten centers (41.7%) reported the use of a TBI management guideline, and 15 (62.5%) implemented CT protocols. Ten DTCs reported implementation of intervention strategies for suspected raised intracranial pressure (ICP) before conducting a CT scan, and 6 NTCs also followed this practice (83.3% vs 50.0%, p = 0.083). ED management for children with TBI was comparable between DTCs and NTCs in the following aspects: neuroimaging, airway management, ICP monitoring, fluid resuscitation, anticoagulant therapy, and serum glucose control. Hyperventilation therapy for raised ICP was used by 33.3% of sites. CONCLUSIONS: This study evaluated pediatric TBI management and infrastructure among 24 centers. Limited differences in prehospital care and ED management for pediatric patients with TBI were observed between DTCs and NTCs. Both DTCs and NTCs showed variation in the implementation of current TBI management guidelines. There is an urgent need to investigate specific barriers to guideline implementation in these regions.
