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.

Randomized Controlled Trial
Femoral nerve block: Assessment of postoperative analgesia in arthroscopic anterior cruciate ligament reconstruction.
Knee anterior cruciate ligament reconstruction (ACLR) may be painful in the postoperative period. The primary objective of this study was to evaluate whether the use of femoral nerve block (FNB) associated with spinal anesthesia would improve the postoperative pain treatment in ACLR and the secondary objectives were to evaluate tramadol request and adverse events. ⋯ Analgesia was more effective with the combination of spinal and FNB, which allowed better control of postoperative pain, assessed 12 hours after anesthesia. There was no difference in tramadol request. Patients in this study had no serious adverse events; however, one must be attentive to motor paralysis and the possibility of falling when FNB is performed.
