Objectives: Describe prehospital tranexamic acid (TXA) use and appropriateness within a major trauma pediatric population, and identify the factors associated with its use., Design: Multicenter, retrospective study, 2014-2020., Setting: Data were extracted from a multicenter French trauma registry including nine trauma centers within a physician-led prehospital emergency medical services (EMS) system., Patients: Patients less than 18 years old were included. Those who did not receive prehospital intervention by a mobile medical team and those with missing data on TXA administration were excluded., Interventions: None., Measurements and Main Results: Nine-hundred thirty-four patients (median [interquartile range] age: 14 yr [9-16 yr]) were included, and 68.6% n = 639) were male. Most patients were involved in a road collision (70.2%, n = 656) and suffered a blunt trauma (96.5%; n = 900). Patients receiving TXA (36.6%; n = 342) were older (15 [13-17] vs 12 yr [6-16 yr]) compared with those who did not. Patient severity was higher in the TXA group (Injury Severity Score 14 [9-25] vs 6 [2-13]; p < 0.001). The median dosage was 16 mg/kg (13-19 mg/kg). TXA administration was found in 51.8% cases ( n = 256) among patients with criteria for appropriate use. Conversely, 32.4% of patients ( n = 11) with an isolated severe traumatic brain injury (TBI) also received TXA. Age (odds ratio [OR], 1.2; 95% CI, 1.1-1.2), A and B prehospital severity grade (OR, 7.1; 95% CI, 4.1-12.3 and OR, 4.5; 95% CI, 2.9-6.9 respectively), and year of inclusion (OR, 1.2; 95% CI, 1.1-1.3) were associated with prehospital TXA administration., Conclusions: In our physician-led prehospital EMS system, TXA is used in a third of severely injured children despite the lack of high-level of evidence. Only half of the population with greater than or equal to one criteria for appropriate TXA use received it. Conversely, TXA was administered in a third of isolated severe TBI. Further research is warranted to clarify TXA indications and to evaluate its impact on mortality and its safety profile to oversee its prescription., Competing Interests: Dr. Claustre’s institution received funding from the Regional Agency for Health. Dr. Fraticelli disclosed work for hire. Dr. Jacquet disclosed the off-label product use of Tranexamic acid. The remaining authors have disclosed that they do not have any potential conflicts of interest., (Copyright © 2022 by the Society of Critical Care Medicine and the World Federation of Pediatric Intensive and Critical Care Societies.)

Background and Aims: Intracranial Hypertension (ICH) is a life-threatening complication of brain injury. The invasive measurement of intracranial pressure (ICP) remains the gold standard to diagnose ICH. Measurement of Optic Nerve Sheath Diameter (ONSD) using ultrasonography is a non-invasive method for detecting ICH. However, data on paediatric brain injury are scarce. The aim of the study was to determine the performance of the initial ONSD measurement to predict ICH occurring in children with severe brain injury and to describe the ONSD values in a control group., Methods: In this cross-sectional study, ONSD was measured in children aged 2 months-17 years old with invasive ICP monitoring: before placement of ICP probe and within the 60 min after, and then daily during 3 days. ONSD was also measured in a control group., Results: Ninety-nine patients were included, of whom 97 were analysed, with a median (IQR) age of 8.7 [2.3-13.6] years. The median (IQR) PIM 2 score was 6.6 [4.4-9.7] and the median (IQR) PELOD score was 21 [12-22]. Aetiologies of brain injury were trauma ( n = 72), infection ( n = 17) and stroke ( n = 8). ICH occurred in 65 children. The median (IQR) ONSD was 5.58 mm [5.05-5.85]. ONSD performed poorly when it came to predicting ICH occurrence within the first 24 h (area under the curve, 0.58). There was no significant difference between the ONSD of children who presented with ICH within the first 24 h and the other children, with a median (IQR) of 5.6 mm [5.1-5.9] and 5.4 mm [4.9-5.8], respectively. Infants aged less than 2 years had a median (IQR) ONSD of 4.9 mm [4.5-5.2], significantly different from children aged more than 2 years, whose median ONSD was 5.6 mm [5.2-5.9]. Age, aetiology or ICP levels did not change the results. Thirty-one controls were included, with a median age of 3.7 (1.2-8.8) years. The median (IQR) of their ONSD measurement was 4.5 mm [4.1-4.8], significantly lower than the patient group., Conclusion: In a paediatric severe brain injury population, ONSD measurement could not predict the 24 h occurrence of ICH. Severity of patients, timing and conditions of measurements may possibly explain these results., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Cour-Andlauer, Portefaix, Wroblewski, Rabilloud, Bordet, Cogniat, Didier, Pouyau, Valla, Kassai-Koupai, Siméon, Ginhoux, Courtil-Teyssedre and Javouhey.)

The latest French Guidelines for the management in the first 24hours of patients with severe traumatic brain injury (TBI) were published in 1998. Due to recent changes (intracerebral monitoring, cerebral perfusion pressure management, treatment of raised intracranial pressure), an update was required. Our objective has been to specify the significant developments since 1998. These guidelines were conducted by a group of experts for the French Society of Anesthesia and Intensive Care Medicine (Société francaise d'anesthésie et de réanimation [SFAR]) in partnership with the Association de neuro-anesthésie-réanimation de langue française (ANARLF), The French Society of Emergency Medicine (Société française de médecine d'urgence (SFMU), the Société française de neurochirurgie (SFN), the Groupe francophone de réanimation et d'urgences pédiatriques (GFRUP) and the Association des anesthésistes-réanimateurs pédiatriques d'expression française (ADARPEF). The method used to elaborate these guidelines was the Grade ® method. After two Delphi rounds, 32 recommendations were formally developed by the experts focusing on the evaluation the initial severity of traumatic brain injury, the modalities of prehospital management, imaging strategies, indications for neurosurgical interventions, sedation and analgesia, indications and modalities of cerebral monitoring, medical management of raised intracranial pressure, management of multiple trauma with severe traumatic brain injury, detection and prevention of post-traumatic epilepsia, biological homeostasis (osmolarity, glycaemia, adrenal axis) and paediatric specificities., (Copyright © 2017 The Authors.

Introduction: The use of vegetable beverages improperly called « vegetable milk » is promoted by food faddism to replace dairy products, even in infant diet whereas it is totally inadequate., Case Reports: Case 1: a 9 month-old infant fed by a rice beverage for 2 months presented hypoalbuminemia (7 g/L) with kwashiorkor syndrome complicated by severe sepsis. Case 2: a 14 month-old infant fed by a rice beverage for 2 months had iron and vitamin B12 deficiency with deep anemia (Hb 35 g/L) and tissue hypoxia (hyperlactacidemia). Case 3: a 13 month-old infant fed by an almond beverage during 3 weeks presented metabolic alkalosis with hypochloremia due to sodium and chloride deficiency and revealed by hypoventilation. Case 4: a 2,5 month-old infant with epileptic encephalopathy was fed by several vegetable beverages (almond, nut, chestnut and soy) for a month and a half and presented deep hyponatremia (96 mmol/L) with coma and respiratory acidosis caused by aspiration pneumonia. He died secondarily., Discussion: Deficiencies promote infections and severe metabolic disorders. Clinical polymorphism lead to diagnosis wandering that can be noxious. The reasons of these diet changes can be nutritional ignorance, perceived milk intolerance or food faddism, sometimes on the advice of an alternative medicine physician. Parental restricted diet or infant immunization recommendations negligence should warn about associated nutritional errors in young infants., Conclusion: These avoidable pathologies frequently caused by well-intending but misinformed parents must be reported to Nutrivigilance. This behaviour can be life threatening and must lead, in the most severe cases, to prosecution., (Copyright © 2012 Elsevier Masson SAS. All rights reserved.)
