Contemporary data suggest that approximately 18% of patients undergoing surgery will develop a major postoperative complication, and 3% to 5% will die prior to hospital discharge. Patients who develop a postoperative complication are at an increased risk of long-term mortality. Multiple studies have shown that perioperative hemodynamic optimization reduces the risk of postoperative complications and death in elective noncardiac surgical patients.

Randomized Controlled Trial
Continuous administration of landiolol reduced QT dispersion in postoperative patients.
To determine the changes in QT dispersion (QTD) in the standard electrocardiogram (ECG) of postoperative patients and the effect of landiolol on QTD. ⋯ Continuous administration of landiolol prevents the increase in QTD found on the morning in postoperative patients. Landiolol demonstrated a possible antiarrhythmic effect by improving the imbalance of repolarization.

Observational Study
Fiberoptic assessment of the Laryngeal Mask Airway (Laryseal) position after one hour of positive pressure ventilation: an observational study.
To determine, by fiberoptic endoscope, malpositioning of the Laryngeal Mask Airway (LMA) and other extraglottic devices. ⋯ LMA position may change spontaneously with time during PPV, especially when the LMA position is not optimum at the time of insertion. The LMA should be adequately inserted with all possible measures in cases with general anesthesia and PPV. Fiberoptic assessment of LMA position intraoperatively may be advantageous.

To investigate whether Type O blood group status is associated with increased intraoperative blood loss and requirement of blood transfusion in extensive spine surgery. ⋯ There was no association between Type O blood and increased intraoperative blood loss or blood transfusion requirement during extensive spine surgery, with similar hospital LOS in Type O and non-O patients.

Randomized Controlled Trial
Dexmedetomidine reduces pain associated with rocuronium injection without causing a decrease in BIS values: a dose-response study.
To examine whether dexmedetomidine reduces the injection pain of propofol and rocuronium and to investigate whether the decrease in injection pain is associated with the known sedative action of dexmedetomidine. ⋯ Dexmedetomidine reduced pain associated with rocuronium injection in a dose-dependent manner. This effect was not associated with the decrease in BIS value.
