Visual AbstractThis is a visual representation of the abstract.

[Prehospital treatment of polytrauma : Ongoing challenge in prehospital emergency services].

Tscherne was the first to define the term polytrauma in 1966 as "multiple injuries to different regions of the body sustained simultaneously, with at least one injury or the combination of these injuries being life-threatening". This definition highlights the essential pathophysiological paradigm of polytrauma, with the life-threating characteristics resulting from injuries to multiple organ systems. The treatment of polytrauma patients begins at the scene of the accident.

Kidney Injury in Critically Ill Patients Treated with Vancomycin and Zosyn or an Alternative: A Systematic Review and Meta-Analysis.

Zosyn (piperacillin-tazobactam; Pfizer Medical, New York, NY), a valuable antibiotic against gram-negative bacteria, combined with vancomycin (Z+V) is known for its high incidence of acute kidney injury (AKI), particularly in the intensive care unit (ICU), leading to the frequent use of alternatives for gram-negative coverage (Alt+V). Because there are limited data describing AKI on these alternative antibiotic agents, a systematic review and meta-analysis was conducted to determine if these regimens were indeed associated with decreased rates of AKI. A literature review was performed electronically from its inception to November 1, 2018, screening for relevant literature by title, abstract and full text according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines within the following databases: PubMed/Medline, CINAHL, Scopus, and Cochrane Central Register of Controlled Trials.
