The addition of alfentanil or atracurium to lidocaine solution for intravenous regional anaesthesia of the arm may have advantages with respect to improved muscle relaxation and better analgesia. The study investigates these possibilities. ⋯ No clinical benefits of adding alfentanil or atracurium to lidocaine solution for intravenous regional anaesthesia of the arm could be shown.

The study investigated the effect of acute normovolaemic haemodilution on haemodynamics, blood flow and oxygen transport variables with regard to skeletal muscle tissue oxygenation in a canine model. ⋯ In acute normovolaemic haemodilution to the level of Hct of 25%, the ratio between tPO2 and cardiac index decreases in the healthy dog, indicating an uneconomic relation at the threshold of Hct of 25%.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of different priming techniques on the onset time and intubating conditions of rocuronium.
The aim was to compare the effects of two different priming doses and priming intervals with the standard intubating dose of rocuronium on the onset time and intubation conditions. ⋯ Priming with a 3 min priming interval was effective when rapid tracheal intubation with rocuronium was necessary. However, priming with rocuronium should be used carefully with special attention given to the possibility of hypoxia and aspiration of gastric contents in awake patients.
