Randomized Controlled Trial
Intravenous dexamethasone as an adjunct to improve labor analgesia: A randomized, double-blinded, placebo controlled clinical trial.
To study the role of intravenous (i.v.) dexamethasone as an analgesic adjunct in labor analgesia. ⋯ I.v. dexamethasone significantly decreased hourly average drug consumption of levobupivacaine-fentanyl combination through the epidural route, demonstrating the epidural drug dose sparing effect during labor analgesia.

Randomized Controlled Trial Comparative Study
Effective volumes of 1.5% mepivacaine with different sodium concentration for ultrasound guided popliteal block.
To determine if a solution of 1.5% mepivacaine diluted with 5% dextrose, which decreases the sodium concentration by 30%, results in reduced volume requirements for a complete sensory block, in the case of an ultrasound guided popliteal nerve block. ⋯ A dilution of 1.5% mepivacaine with 30% less sodium concentration does not decrease volume requirement for ultrasound guided sciatic nerve block at popliteal level.

Randomized Controlled Trial Comparative Study
Preprocedural ultrasound assessment does not improve trainee performance of spinal anesthesia for obstetrical patients: a randomized controlled trial.
This randomized controlled trial was designed to evaluate the efficacy of additional information from preprocedure ultrasound examination to aid anesthesiology trainees performing spinal anesthesia for obstetric patients. ⋯ In this study of junior anesthesia trainees performing obstetrical spinal anesthesia with preprocedure ultrasound and landmark technique or landmark technique only, no significant difference was observed in the number of attempts, duration of spinal placement, subjective ease of spinal placement, or any other measured secondary outcome.

To assess the usefulness of the new NEMA (Neck Circumference Minus Acromion-Acromion Distance) parameter, in preoperative identification of patients' difficult intubation and compare it with other commonly used scales and tests. ⋯ It seems that none of the known bedside tests for predicting difficult intubation have a discriminating power sufficient for clinicians. Our study draws attention to a novel parameter, called NEMA, which appears to be a strong predictor of DEI, especially in combination with the Mallampati scale.
