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
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.

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.

Randomized Controlled Trial
Betamethasone in prevention of postoperative nausea and vomiting following breast surgery.
To investigate whether betamethasone decreases the incidence of postoperative nausea/vomiting (PONV) and reduces postoperative pain following partial mastectomy. ⋯ Preoperative betamethasone reduces the severity of PONV and pain in patients undergoing elective breast surgery.

Randomized Controlled Trial Comparative Study
Spinal anesthesia protects against perioperative hyperglycemia in patients undergoing hip arthroplasty.
To determine whether spinal anesthesia blunts surgical stress reactions and results in less perioperative hyperglycemia. ⋯ Spinal anesthesia attenuates the hyperglycemic response to surgical stimuli in diabetics and nondiabetic patients.
