This systematic review found no convincing evidence that one sedative agent is more efficacious than another for improvement of patient-centered outcomes, intracranial pressure, or cerebral perfusion pressure in critically ill adults with severe traumatic brain injury. High bolus doses of opioids, however, have potentially deleterious effects on intracranial pressure and cerebral perfusion pressure. Adequately powered, high-quality, randomized controlled trials are urgently warranted.

Background: Evidence regarding longer-term psychiatric, psychological, and behavioural outcomes (for example, anxiety, mood disorders, depression, and attention disorders) following mild traumatic brain injury (mTBI) in children and adolescents has not been previously synthesized. Objective: To conduct a systematic review of the available evidence examining psychiatric, psychological, and behavioural outcomes following mTBI in children and adolescents.Materials and Methods: Nine electronic databases were systematically searched from 1980 to August 2014. Studies selected met the following criteria: original data; study design was a randomized controlled trial, quasi-experimental design, cohort or historical cohort study, case-control study, or cross-sectional study; exposure included mTBI (including concussion); population included children and adolescents (<19 years) at the time of mTBI, as well as a comparison group (for example, healthy children, children with orthopaedic injuries); and included psychiatric, psychological, or behavioural outcomes (for example, anxiety, mood disorders, depression, attention disorders). Two authors independently assessed the quality and level of evidence with the Downs and Black (DB) criteria and Oxford Centre of Evidence-Based Medicine (OCEBM) model, respectively, for each manuscript. Results: Of 9472 studies identified in the initial search, 30 were included and scored. Heterogeneity in methodology and injury definition precluded meta-analyses. The median methodological quality for all 30 studies, based on the DB criteria, was 15/33 (range 6 to 19). The highest level of evidence demonstrated by all reviewed studies was level 2b based on OCEBM criteria, with the majority (28/30 studies) classified at this level. Based on the literature included in this systematic review, psychological and psychiatric problems in children with a history of mTBI were found to be more prevalent when mTBI is Ré sultats : Sur les 9 472 études repérées dans la recherche initiale, 30 ont été incluses et notées. L'hétérogénéité de la méthodologie et la définition du traumatisme excluaient les méta-analyses. La qualité méthodologique moyenne pour les 30 études, selon les critères DB, était de 15/33 (écart 6-19). Le niveau le plus élevé des données probantes démontré par toutes les études examinées était le niveau 2b, selon les critères de l'OCEBM, la majorité des études (28/30) étant classées à ce niveau. D'après la littérature incluse dans cette revue systématique, les problèmes psychiatriques et psychologiques des enfants ayant des antécédents de TCCb se sont révélés plus prévalents quand le TCCb est associé à une hospitalisation, quand l'évaluation a lieu plus tôt dans la période de rétablissement (c.-à-d., qui se résout avec le temps), quand il y a de multiples TCCb passés, chez des personnes souffrant d'une maladie psychiatrique préexistante, quand les résultats sont basés sur la mémoire rétrospective, et quand le groupe de comparaison est formé d'enfants en santé non blessés (par oppositi...

The reported clinical presentation of tension pneumothorax depends on the ventilatory status of the patient. This may have implications for improving the diagnosis and treatment of this life-threatening disorder.

IntroductionInitial abbreviated surgery with planned reoperation (damage control surgery) is frequently used for major trauma patients to rapidly control haemorrhage while limiting surgical stress. Although damage control surgery may decrease mortality risk among the severely injured, it may also be associated with several complications when inappropriately applied. We seek to scope the literature on trauma damage control surgery, identify its proposed indications, map and clarify their definitions, and examine the content and evidence on which they are based. We also seek to generate a comprehensive list of unique indications to inform an appropriateness rating process.Methods and analysisWe will search 11 electronic bibliographic databases, included article bibliographies and grey literature sources for citations involving civilian trauma patients that proposed one or more indications for damage control surgery or a damage control intervention. Indications will be classified into a predefined conceptual framework and categorised and described using qualitative content analysis. Constant comparative methodology will be used to create, modify and test codes describing principal findings or injuries (eg, bilobar liver injury) and associated decision variables (eg, coagulopathy) that comprise the reported indications. After a unique list of codes have been developed, we will use the organisational system recommended by the RAND/University of California, Los Angeles (RAND-UCLA) Appropriateness Rating Method to group principal findings or injuries into chapters (subdivided by associated decision variables) according to broader clinical findings encountered during surgical practice (eg, major liver injury).Ethics and disseminationThis study will constitute the first step in a multistep research programme aimed at developing appropriate, evidence-informed indications for damage control in civilian trauma patients. With use of an integrated knowledge translation intervention that includes collaboration with surgical practice leaders, this research may allow for development of indications that are more likely to be relevant to and used by surgeons. Ethics approval is not required for this study.

Point-of-care ultrasound has modest diagnostic accuracy for diagnosing nephrolithiasis. The finding of moderate or severe hydronephrosis is highly specific for the presence of any stone, and the presence of any hydronephrosis is suggestive of a larger (>5 mm) stone in those presenting with renal colic.

Despite the near universal adaptation of gentle mechanical ventilation, surfactant use and non-invasive respiratory support, bronchopulmonary dysplasia (BPD) remains one of the most common respiratory morbidities in very low birth weight (VLBW) infants. Thus, the objective of this review was to evaluate the efficacy of intra-tracheal administration of budesonide-surfactant mixture in preventing bronchopulmonary dysplasia (BPD) in very low birth weight (VLBW) infants. MEDLINE, EMBASE, and PubMed were searched for randomized clinical trials in which intra-tracheal administration of budesonide-surfactant was used to prevent BPD in infants. The primary outcomes were BPD and composite outcome of death or BPD. Meta-analysis of the two clinical trials revealed that infants who received intra-tracheal instillation of budesonide-surfactant mixture demonstrated 43% reduction in the risk of BPD (RR: 0.57; 95%CI: 0.43-0.76, NNT = 5). Although mortality was not different between the groups (OR: 0.61; 95%CI: 0.34-1.04), a 40% reduction was observed in the composite outcome of death or BPD in the budesonide-surfactant group (RR: 0.60; 95%CI: 0.49-0.74, NNT = 3). Thus, this review concludes that intra-tracheal administration of budesonide-surfactant combination was associated with decreased incidence of BPD alone or composite outcome of death or BPD in VLBW infants though there is a need for larger trials before it can be recommended as a standard of care.
