Review Meta Analysis Comparative Study
Semi-invasive measurement of cardiac output based on pulse contour: a review and analysis.
The aim of this review was to provide a meta-analysis of all five of the most popular systems for arterial pulse contour analysis compared with pulmonary artery thermodilution, the established reference method for measuring cardiac output (CO). The five investigated systems are FloTrac/Vigileo(®), PiCCO(®), LiDCO/PulseCO(®), PRAM/MostCare(®), and Modelflow. ⋯ During hemodynamic instability, CO measurement based on continuous arterial pulse contour analysis shows only limited agreement with intermittent bolus thermodilution. The calibrated systems seem to deliver more accurate measurements than the auto-calibrated or the non-calibrated systems. For reliable use of these semi-invasive systems, especially for critical therapeutic decisions during hemodynamic disorders, both a strategy for hemodynamic optimization and further technological improvements are necessary.

Randomized Controlled Trial Multicenter Study Comparative Study
The increases in potassium concentrations are greater with succinylcholine than with rocuronium-sugammadex in outpatient surgery: a randomized, multicentre trial.
Succinylcholine provides rapid onset of neuromuscular blockade and short duration of action, but its administration may be associated with hyperkalemia. Rocuronium is not known to increase potassium concentration, has fast onset of activity, and can be rapidly reversed by sugammadex. This study evaluated changes in plasma potassium concentrations in patients randomized either to rocuronium followed by sugammadex reversal or to succinylcholine in ambulatory surgery. ⋯ NCT00751179).

Randomized Controlled Trial
A styletted tracheal tube with a posterior-facing bevel reduces epistaxis during nasal intubation: a randomized trial.
Epistaxis is a common complication of nasal intubation. Ease of insertion of the tracheal tube may be influenced by bevel orientation and tip bending. We examined ease of insertion and epistaxis with two tubes with different orientations and with or without a stylet to modify tip bending. ⋯ UMIN Clinical Trials Registry (UMIN-CTR), UMIN000011327.

Observational Study
An observational cohort study to assess glycosylated hemoglobin screening for elective surgical patients.
Uncontrolled blood glucose is associated with a higher incidence of surgical site infections, greater utilization of resources, and increased mortality. Preoperative screening for diabetes in elective surgical patients is not routinely performed. The purpose of this study was to examine blood glucose control in a preoperative surgical population. ⋯ Many elective surgical patients are at risk for unrecognized postoperative hyperglycemia and associated adverse outcomes. Random blood sugar testing has limited value and HbA1c may be a more appropriate test for the preoperative assessment of diabetic patients.
