Randomized Controlled TrialThe protective effect of human atrial natriuretic peptide on renal damage during cardiac surgery.
Acute kidney injury (AKI) is one of the critical complications after cardiac surgery. In the kidney, angiotensin II (Ang II) is formed by independent mechanisms, and activity of the intrarenal renin-angiotensin-aldosterone (RAAS) system contributes to the progression of kidney damage. Although atrial natriuretic peptide (ANP) exerts protective effects against renal injury by inhibiting the RAAS, the mechanisms of this effect have not been completely clarified. We investigated how human ANP (hANP) could prevent renal damage induced by cardiopulmonary bypass. ⋯ hANP demonstrated renal protective effects during cardiac surgery, and could possibly reduce the incidence of AKI after ischemia-reperfusion surgery. Moreover, this protective effect of hANP is likely induced by inhibition of the intrarenal RAAS.

Randomized Controlled TrialHyperinsulinemic normoglycemia decreases glucose variability during cardiac surgery.
Increased glucose variability may be associated with worse outcomes in critically ill patients. Hyperinsulinemic normoglycemia provides intensive glucose control during surgery and may reduce glucose variability. Our objective was to compare glycemic variability between two methods of glucose control in cardiac surgical patients: hyperinsulinemic normoglycemia vs standard insulin infusion. We also assessed whether the effect differed between patients with and without diabetes mellitus. ⋯ Hyperinsulinemic normoglycemia decreases glucose variability for cardiac surgical patients with a stronger effect in nondiabetic patients.

Randomized Controlled Trial Comparative StudyFosaprepitant versus droperidol for prevention of PONV in craniotomy: a randomized double-blind study.
Postoperative nausea and vomiting (PONV) is a common complication after craniotomy. Vomiting may be a potentially hazardous complication in neurosurgical patients. We compared the efficacy of fosaprepitant and droperidol for the prevention of PONV, vomiting in particular, after craniotomy. ⋯ Based on the results, fosaprepitant was more effective than droperidol in the prevention of vomiting after craniotomy over the entire 72-h study period. However, there was no difference in the incidence of nausea and antiemetic use.

Randomized Controlled Trial Comparative StudyComparison of short-axis out-of-plane versus long-axis in-plane ultrasound-guided radial arterial cannulation in adult patients: a randomized controlled trial.
The current available literature is not unanimous in reporting the utility of short-axis and long-axis techniques for radial artery cannulation in both adults and children. This study was designed to compare short-axis out-of-plane (SA-OOP) and long-axis in-plane (LA-IP) techniques in ultrasound-guided radial artery cannulation in adults. ⋯ The first-attempt cannulation success rate and cannulation time in adult patients are similar in ultrasound-guided radial artery cannulation with both short-axis as well as long-axis techniques.

Randomized Controlled TrialThe effect of dexmedetomidine pretreatment on the median effective bolus dose of propofol for facilitating laryngeal mask airway insertion.
We designed this study to investigate the effect of dexmedetomidine (1 μg/kg) pretreatment on the median effective dose (ED50) of propofol for facilitating successful laryngeal mask airway (LMA) insertion compared to propofol alone. ⋯ Pretreatment with dexmedetomidine 1 μg/kg could reduce the propofol requirement by 38 % for facilitating LMA insertion without prolonged respiratory depression and hemodynamic instability.
