Comparative Study
Effects of Plasma-lyte A, lactated Ringer's, and normal saline on acid-base status and intestine injury in the initial treatment of hemorrhagic shock.
Several kinds of crystalloid solutions have been used in the treatment of hemorrhagic shock (HS). Clinicians are faced with how to select the resuscitation fluids. The aim of the present study is to compare the effects of 3 crystalloid solutions, such as normal saline (NS), lactated Ringer's (LR), and Plasma-lyte A (PA), on acid-base status and intestine injury in rats subjected to HS. ⋯ Although the 3 crystalloid solutions play different roles, PA is better at correcting the acid-base balance and improving intestine injury during HS than NS and LR.

There are more than 18 million patients diagnosed with sepsis every year. In China, Xuebijing (XBJ) injection is a traditional medicine that is widely used in the treatment of sepsis. However, the efficacy of XBJ in treatment of randomized controlled trials (RCTs) remains unclear. This meta-analysis was to evaluate the clinical efficacy of XBJ based on randomized case-control studies. ⋯ XBJ injection has a significant clinical efficacy in the therapy of patients with sepsis. However, there is a need for more randomized, lager-sample size, high-quality, and multicenter studies to confirm the extract efficacy of XBJ injection.

Randomized Controlled Trial
Success of ultrasound-guided versus landmark-guided arthrocentesis of hip, ankle, and wrist in a cadaver model.
The objectives of this study were to evaluate emergency medicine resident-performed ultrasound for diagnosis of effusions, compare the success of a landmark-guided (LM) approach with an ultrasound-guided (US) technique for hip, ankle and wrist arthrocentesis, and compare change in provider confidence with LM and US arthrocentesis. ⋯ EM residents were able to successfully identify joint effusions with ultrasound, however we were unable to detect significant differences in actual procedural success between the two modalities. Further studies are needed to define the role of ultrasound for arthrocentesis in the emergency department.
