BackgroundDamage control strategies play an important role in trauma patient management. One such strategy, hypotensive resuscitation, is being increasingly employed. Although several randomized controlled trials have reported its benefits, the mortality benefit of hypotensive resuscitation has not yet been systematically reviewed.ObjectivesTo conduct a meta-analysis of the efficacy of hypotensive resuscitation in traumatic hemorrhagic shock patients relative to mortality as the primary outcome, with acute respiratory distress syndrome (ARDS), acute kidney injury (AKI), and multiple organ dysfunction as the secondary outcomes.MethodsPubMed, Medline-Ovid, Scopus, Science Direct, EMBASE, and CNKI database searches were conducted. An additional search of relevant primary literature and review articles was also performed. Randomized controlled trials and cohort studies reporting the mortality rate associated with hypotensive resuscitation or limited fluid resuscitation were selected. The random-effects model was used to estimate mortality and onset of other complications.ResultsOf 2114 studies, 30 were selected for this meta-analysis. A statistically significant decrease in mortality was observed in the hypotensive resuscitation group (risk ratio [RR]: 0.50; 95% confidence interval [CI]: 0.40–0.61). Heterogeneity was observed in the included literature (I2: 27%; degrees of freedom: 23; p = 0.11). Less usage of packed red cell transfusions and fluid resuscitations was also demonstrated. No significant difference between groups was observed for AKI; however, a protective effect was observed relative to both multiple organ dysfunction and ARDS.ConclusionsThis meta-analysis revealed significant benefits of hypotensive resuscitation relative to mortality in traumatic hemorrhagic shock patients. It not only reduced the need for blood transfusions and the incidences of ARDS and multiple organ dysfunction, but it caused a non-significant AKI incidence.
Objective: This study aimed to assess the accuracy of the revised BAUX score for predicting mortality among the major burn patients with acute kidney injury (AKI) compared with non-AKI group. The epidemiologic information and risk factors of AKI in major burn patients were also the point of interest. Methods: This study was a retrospective cohort study. The medical records of 144 major burn patients admitted at the burns unit of Siriraj Hospital from 2010-2016 were reviewed and important data were retrieved. Results: Age, hypertension, diabetes mellitus, severity of the burn injuries, and inhalation injuries were the factors related to AKI in major burn patients. The mortality rate due to AKI in burn patients was high (44.4%). The accuracy of the revised BAUX score in predicting the mortality among the major burn patients from our series was only fair (66.7%). Conclusion: AKI affected on mortality of the major burn patients. Until the better predictor comes up, the revised BAUX score should be considered as a predictor of mortality in these patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
