Randomized Controlled Trial Comparative Study[Brachial plexus block with levobupivacaine at the humeral canal: comparison of a small volume at high concentration with a large volume at low concentration].
To assess differences in the brachial plexus block in 2 groups who received the same dose of levobupivacaine: 1 group received a small volume of solution at high concentration and the other group received a large volume in solution at low concentration. ⋯ The success rate was lower in the group receiving the smaller volume at a higher concentration. It is advisable to administer local anesthetics in larger volumes at lower concentrations to improve block quality. Latency and duration were similar in both groups.

Case Reports[Hydroxyethyl starch 130/0.4 can be useful to prevent a hemodynamic response to a single dose of remifentanil].
Intravenous propofol and remifentanil are often used in anesthesia. The combined use of these drugs tends to cause hemodynamic depression. We describe the absence of hemodynamic effects in response to infusion of propofol and remifentanil when hydroxyethyl starch (HES) 130/0.4 was also administered. ⋯ They then received a single dose of 2 microg x kg(-1) of remifentanil during total intravenous anesthesia (TIVA) with propofol and remifentanil before placement of a Mayfield head holder. No changes in mean blood pressure or heart rate were observed in either patient after the remifentanil bolus when they have received HES 130/0.4 during TIVA with propofol and remifentanil HES 130/0.4 may play an active role in preventing a hemodynamic response to remifentanil bolus. This hypothesis should be tested in a randomized controlled trial.

[Identification of the epidural space: usual practice among Spanish anesthesiologists].
To determine what methods are habitually used by Spanish anesthesiologists to identify the epidural space. ⋯ The procedure used most often by Spanish anesthesiologists to identify the epidural space is the LOR-A technique; however, over a quarter of Spanish users of LOR-A do not recommend it.

[Preoperative use of intravenous iron: a new transfusional therapy].
Improving preoperative hemoglobin levels reduces transfusion requirements. The availability in Spain of iron sucrose formulas with good safety profiles has added a new therapeutic option for treating anemia. The aim of this study was to demonstrate the usefulness of preoperative intravenous infusion of iron for improving hemoglobin level before elective major orthopedic surgery. ⋯ Intravenous iron therapy improved the preoperative hemoglobin levels in anemic patients scheduled for major orthopedic surgery. This is a new intravenous treatment approach to evaluate.
