Randomized Controlled Trial Comparative Study
Effects of acute plasma volume expansion on renal perfusion, filtration, and oxygenation after cardiac surgery: a randomized study on crystalloid vs colloid.
In the present randomized study, we evaluated the differential effects of a colloid and a crystalloid fluid on renal oxygen delivery (RD(O2)), glomerular filtration (GFR), renal oxygen consumption ((RV(O2))), and the renal oxygen supply-demand relationship (i.e., renal oxygenation) after cardiac surgery with cardiopulmonary bypass. ⋯ NCT01729364.

Randomized Controlled Trial Comparative Study
Comparison of contrast flow and clinical effectiveness between a modified paramedian interlaminar approach and transforaminal approach in cervical epidural steroid injection.
The different methods of cervical epidural injection include the median or paramedian interlaminar (PI) approach and the transforaminal (TF) approach. We hypothesized that the modified PI (mPI) approach could deliver drugs suitably and safely into the anterior epidural space compared with the TF approach. ⋯ This result suggests that the mPI approach allows for suitable and safe delivery of drugs into the anterior epidural space.
