An anatomical study of the parasacral block using magnetic resonance imaging of healthy volunteers.
The parasacral approach to sciatic blockade is reported to be easy to learn and perform, with a high success rate and few complications. ⋯ These findings question the reliability of the anatomical landmarks of the parasacral block and raise the possibility of frequent visceral puncture using this technique.

The effect of peripherally administered CDP-choline in an acute inflammatory pain model: the role of alpha7 nicotinic acetylcholine receptor.
CDP-choline (citicholine; cytidine-5'-diphosphate choline) is an endogenously produced nucleotide which, when injected intracerebroventricularly, exerts an antinociceptive effect in acute pain models mediated by central cholinergic mechanisms and alpha7 nicotinic acetylcholine receptors (alpha7nAChR). Previous reports also suggest that the peripheral cholinergic system has an antiinflammatory role mediated by alpha7nAChRs on macrophages. ⋯ The results of this study suggest that intraplantar CDP-choline has antihypersensitivity and antiinflammatory effects mediated via alpha7nAChRs in the carrageenan-induced inflammatory pain model.

Incentive payments to academic anesthesiologists for late afternoon work did not influence turnover times.
Anesthesiologists are often paid extra for hours worked in the late afternoon and evening. Although anesthesiologists have little influence on their operating room (OR) assignments and workloads late in the afternoon, they can influence turnover times. ⋯ Our results suggest that hospital administrators, deans, and other executives need not be especially concerned about disincentives produced by methods of internal compensation of anesthesiologists on highly visible OR turnover times late in afternoons.

The effect of inguinal compression, Valsalva maneuver, and reverse Trendelenburg position on the cross-sectional area of the femoral vein in children.
For facilitation of femoral venous cannulation, the larger cross-sectional area (CSA) of the vein is helpful and can be achieved by inguinal compression, Valsalva maneuver, or the reverse Trendelenburg position. In this study, we evaluated these methods using ultrasonography in children. ⋯ Inguinal compression effectively increases the CSA of the femoral vein and its effect is also prominent in the Trendelenburg position. Valsalva maneuver is more effective in small children. Gravitational position changes have little effect on the size of the femoral vein in children.
