Review Meta Analysis Comparative Study
Clinical benefits of dexmedetomidine versus propofol in adult intensive care unit patients: a meta-analysis of randomized clinical trials.
This meta-analysis was performed to assess the influence of dexmedetomidine and propofol for adult intensive care unit (ICU) sedation, with respect to patient outcomes and adverse events. ⋯ For ICU patient sedation, dexmedetomidine may offer advantages over propofol in terms of decrease in the length of ICU stay and the risk of delirium. However, transient hypertension may occur when dexmedetomidine is administered with a loading dose or at high infusion rates.

Meta Analysis
A meta-analysis of the effectiveness and safety of using tranexamic acid in primary unilateral total knee arthroplasty.
To evaluate the effectiveness and safety of tranexamic acid (TEA) treatment in reducing perioperative blood loss and transfusion for patients receiving primary unilateral total knee arthroplasty (TKA) and to explore the most effective and safe protocol. ⋯ Intravenous TEA could significantly reduce perioperative blood loss and blood transfusion requirements following primary unilateral TKA. Its application is not associated with increased risk of venous thromboembolisms or other adverse events.

Meta Analysis
The necessity of indwelling gastrointestinal decompression after gastrectomy: a meta-analysis.
This meta-analysis was designed to evaluate the necessity of indwelling gastrointestinal decompression after gastrectomy. ⋯ Routine gastrointestinal decompression after gastrectomy does not promote the recovery of gastrointestinal function or reduce the incidence of postoperative complications. In our series, decompression was correlated with a prolonged interval to oral intake, a longer duration of hospitalization, and increased patient discomfort.

Meta Analysis Comparative Study
Preoperative mediastinal and hilar nodal staging with diffusion-weighted magnetic resonance imaging and fluorodeoxyglucose positron emission tomography/computed tomography in patients with non-small-cell lung cancer: which is better?
To compare the diagnostic capability of diffusion-weighted magnetic resonance imaging (DWI) and (18)F-fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) in the N stage assessment in patients with non-small-cell lung cancer. ⋯ Our study has confirmed that DWI has a high specificity for N staging of non-small-cell lung cancer compared with (18)F-FDG PET/CT and has the potential to be a reliable alternative noninvasive imaging method for the preoperative staging of mediastinal and hilar lymph nodes in patients with non-small-cell lung cancer.

Perioperative supplemental oxygen has been proposed to decrease the incidence of surgical site infection (SSI) in colorectal surgery. A number of randomized controlled trials (RCTs) have been reported with inconsistent results. In addition, relevant clinical outcomes other than SSIs have been collected in these studies and have been equivocal. A meta-analysis of RCTs was performed to elucidate the effects of perioperative supplemental oxygen in colorectal surgery on SSI incidence, mortality, ICU admission, and length of stay. ⋯ Perioperative supplemental oxygen in colorectal surgery does not significantly reduce SSI. However, supplemental oxygen appears to confer a mortality benefit, a previously unreported finding. Further RCTs are required to confirm these conclusions.
