Review Meta AnalysisIs the supine position associated with loss of airway patency in unconscious trauma patients? A systematic review and meta-analysis.
Airway compromise is a leading cause of death in unconscious trauma patients. Although endotracheal intubation is regarded as the gold standard treatment, most prehospital providers are not trained to perform ETI in such patients. Therefore, various lateral positions are advocated for unconscious patients, but their use remains controversial in trauma patients. We conducted a systematic review to investigate whether the supine position is associated with loss of airway patency compared to the lateral position. ⋯ Although concerns other than airway patency may influence how a trauma patient is positioned, our systematic review provides evidence supporting the long held recommendation that unconscious trauma patients should be placed in a lateral position.

Risk Factors and Screening Instruments to Predict Adverse Outcomes for Undifferentiated Older Emergency Department Patients: A Systematic Review and Meta-analysis.
A significant proportion of geriatric patients experience suboptimal outcomes following episodes of emergency department (ED) care. Risk stratification screening instruments exist to distinguish vulnerable subsets, but their prognostic accuracy varies. This systematic review quantifies the prognostic accuracy of individual risk factors and ED-validated screening instruments to distinguish patients more or less likely to experience short-term adverse outcomes like unanticipated ED returns, hospital readmissions, functional decline, or death. ⋯ Risk stratification of geriatric adults following ED care is limited by the lack of pragmatic, accurate, and reliable instruments. Although absence of dependency reduces the risk of 1-year mortality, no individual risk factor, frailty construct, or risk assessment instrument accurately predicts risk of adverse outcomes in older ED patients. Existing instruments designed to risk stratify older ED patients do not accurately distinguish high- or low-risk subsets. Clinicians, educators, and policy-makers should not use these instruments as valid predictors of post-ED adverse outcomes. Future research to derive and validate feasible ED instruments to distinguish vulnerable elders should employ published decision instrument methods and examine the contributions of alternative variables, such as health literacy and dementia, which often remain clinically occult.

It has been questioned whether patients with unruptured intracranial aneurysms (IAs) are at a greater risk for the development of intracerebral hemorrhage (ICH) following thrombolytic therapy. We thus performed a meta-analysis to better quantify the risk of post-thrombolysis ICH in patients with acute ischemic stroke and incidental IAs. ⋯ Intravenous thrombolysis was safe among patients with acute ischemic stroke and incidental unruptured IAs. Future prospective studies with much larger sample sizes are required to clarify the significance of the association between pre-existing unruptured IAs and the development of post-thrombolysis ICH.

Rising intracranial pressure (ICP) is a poor prognostic indicator in traumatic brain injury (TBI). Both mannitol and hypertonic sodium solutions are used to treat raised ICP in patients with TBI. ⋯ The evidence shows that both agents effectively lower ICP. There is a trend favouring the use of hypertonic sodium solutions in patients with TBI.

Meta AnalysisThe effects of ursodeoxycholic acid treatment for intrahepatic cholestasis of pregnancy on maternal and fetal outcomes: a meta-analysis including non-randomized studies.
The benefits of ursodeoxycholic acid (UDCA) use for treating intra-hepatic cholestasis of pregnancy (ICP) remain uncertain. A 2010 Cochrane Review of randomized control trials was unable to recommend either for or against the use of UDCA in treating ICP. We conducted a meta-analysis of the literature, including both non-randomized studies (NRSs) and RCTs. The objective of the study was to determine if patients included in NRSs were comparable to those in RCTs, and to determine whether the inclusion of NRSs could strengthen the available evidence and guide clinical practice on UDCA use in women with ICP. ⋯ UDCA treatment should be recommended for women with ICP to reduce adverse maternal and fetal outcomes.
