Randomized Controlled Trial Clinical Trial
Relationship between the right internal jugular vein and carotid artery at ipsilateral head rotation.
Ultrasound-guided right internal jugular vein catheterization (RIJV) should be the first choice to decrease the catheter-related complications in high-risk hemodialysis patients. For this procedure, clinicians should identify the optimum positions of the RIJV, including its lower overlap with the carotid artery (CA) and high cross-sectional area of the vein. The aim of this prospective randomized study to evaluate the effects of mild ipsilateral head rotation combined with Trendelenburg position on RIJV cross-sectional area and its relation to the CA in adult patients. ⋯ As the head was rotated from >30° left to <30° right, the CA-RIJV overlap (from 95% to 57.5%), and the cross-sectional area (from 14.2 mm to 8.7 mm) significantly decreased. In conclusion, when the head was turned to <30° right, the CA-RIJV overlap significantly decreased, and the cross-sectional area also decreased. When clinicians determine the optimal head position before RIJV cannulation, it is important to consider the advantages and disadvantages of the different head positions from >30° left to <30° right.

Randomized Controlled Trial Comparative Study
The effect of HES (130/0.4) usage as the priming solution on renal function in children undergoing cardiac surgery.
Experience with hydroxyethyl starch (HES) in children is limited. This study was conducted to observe the effects of HES or Ringer's lactate (RL) usage as the priming solution on renal functions in children undergoing cardiac surgery. ⋯ We conclude that usage of HES (130/0.4) did not have negative effects on renal function, and it can be used as a priming solution in pediatric patients undergoing cardiac surgery.
