Randomized Controlled Trial Comparative Study
Comparison of the effects and complications of unilateral spinal anesthesia versus standard spinal anesthesia in lower-limb orthopedic surgery.
A restricted sympathetic block during spinal anesthesia may minimize hemodynamic changes. This prospective randomized study compared unilateral and bilateral spinal anesthesia with respect to the intra- and postoperative advantages and complications of each technique. ⋯ When unilateral spinal anesthesia was performed using a low-dose, low-volume and low-flow injection technique, it provides adequate sensory-motor block and helps to achieve stable hemodynamic parameters during orthopedic surgery on a lower limb. Patients were more satisfied with this technique as opposed to the conventional approach. Furthermore, this technique avoids unnecessary paralysis on the non-operated side.

Randomized Controlled Trial
Ondansetron reducing pain on injection of etomidate: a controlled randomized study.
Etomidate causes pain when injected intravenously. In this study we sought to determine if pretreatment by ondansetron reduces the pain on injection of etomidate. ⋯ This study illustrates that pre-treatment with intravenous ondansetron significantly reduces the pain on injection of etomidate.

Randomized Controlled Trial
Impact of preanesthetic information on anxiety of parents and children.
Preoperative Anxiety is a negative factor in anesthetic and surgical experience. Among the strategies for reducing children's anxiety, non-pharmacological strategies are as important as the pharmacological ones, but its validity is still controversial. ⋯ Regardless of the quality of information provided to the guardians, the level and prevalence of anxiety in children were low at WR time and significantly increased at OR time.

Randomized Controlled Trial Comparative Study
Comparative study between doses of intrathecal morphine for analgesia after caesarean.
Analgesia after caesarean section is important because postpartum women with pain have difficulty in mobility, which undermines breastfeeding. Intrathecal morphine provides adequate and prolonged analgesia after cesarean. The aim of this study was to compare the quality of analgesia provided by two doses of intrathecal morphine and its side effects in patients undergoing cesarean section. ⋯ Intrathecal morphine 50 μg provides the same quality of analgesia as 100 μg, with a lower incidence of side effects.

Randomized Controlled Trial
Prospective, randomized clinical trial of laryngeal mask airway Supreme(®) used in patients undergoing general anesthesia.
Supraglottic airway devices are increasingly used as an option to tracheal intubation for elective procedures of varying complexity. The aim of this study was to prospectively evaluate the clinical use of the laryngeal mask airway Supreme(®) (LMAS) in patients undergoing elective breast surgery and compare it with endotracheal tube (ETT). ⋯ The use of the LMAS technique to access airway during general anesthesia for elective breast surgery is as safe and effective as tracheal intubation, with the advantage of promoting smaller hemodynamic response during its management and lower incidence of sore throat and dysphagia in the first hours after surgery.
