Randomized Controlled TrialA Randomized Trial of a Supplemental Alarm for Critically Low Systolic Blood Pressure.
Intraoperative hypotension is associated with complications that might be ameliorated by earlier intervention. We therefore tested the primary hypothesis that a supplemental decision support alert for critically low systolic blood pressure (SBP) decreases the duration of intraoperative hypotension. ⋯ An additional warning for severe hypotension did not reduce the duration of hypotension or hospitalization. Decision support alerts may be more useful for more complicated situations.

Randomized Controlled TrialThe Effect of Systemic Magnesium on Postsurgical Pain in Children Undergoing Tonsillectomies: A -Double-Blinded, Randomized, Placebo-Controlled Trial.
Tonsillectomy is a frequently performed surgical procedure in children; however, few multimodal analgesic strategies have been shown to improve postsurgical pain in this patient population. Systemic magnesium infusions have been shown to reliably improve postoperative pain in adults, but their effects in pediatric surgical patients remain to be determined. In the current investigation, our main objective was to evaluate the use of systemic magnesium to improve postoperative pain in pediatric patients undergoing tonsillectomy. We hypothesized that children who received systemic magnesium infusions would have less post-tonsillectomy pain than the children who received saline infusions. ⋯ Despite a large number of studies demonstrating the efficacy of systemic magnesium for preventing postsurgical pain in adults, we could not find evidence for a significant clinical benefit of systemic magnesium infusion in children undergoing tonsillectomies. Our findings reiterate the importance of validating multimodal analgesic strategies in children that have been demonstrated to be effective in the adult population.

Review Meta Analysis
A Meta-Analysis of Effect of Dietary Salt Restriction on Blood Pressure in Chinese Adults.
The aim of this study was to estimate the effects of dietary salt reduction on blood pressure (BP) in Chinese adults and the effects of China-specific cooking salt-reduction strategies (the use of salt substitutes and salt-restriction spoons). The PubMed and China National Knowledge Infrastructure databases were searched for studies satisfying the search criteria. Outcomes extracted from each included study were 24-h urinary sodium excretion, salt (sodium chloride) intake, and BP before and after dietary salt lowering. ⋯ The effect of salt-substitute use on systolic BP control was substantial among the hypertensive participants (-4.2 mm Hg; 95% CI: -7.0 to -1.3 mm Hg), but the change did not reach statistical significance in hypertensive and normotensive participants combined (-2.31 mm Hg; 95% CI: -5.57 to 0.94 mm Hg). Salt restriction lowers mean BP in Chinese adults, with the strongest effect among hypertensive participants. Future studies of salt-restriction strategies should be report results stratified by hypertension status and adjust for medication use.

Multicenter Study Observational StudyA Multicenter Evaluation of Prolonged Empiric Antibiotic Therapy in Adult ICUs in the United States.
The purpose of this study is to determine the rate of prolonged empiric antibiotic therapy in adult ICUs in the United States. Our secondary objective is to examine the relationship between the prolonged empiric antibiotic therapy rate and certain ICU characteristics. ⋯ Half of all empiric antibiotics ordered in critically ill patients are continued for at least 72 hours in absence of adjudicated infection. Additional studies are needed to confirm these findings and determine the risks and benefits of prolonged empiric therapy in the critically ill.
