[Dexmedetomidine/propofol association for plastic surgery sedation during local anesthesia.].
Dexmedetomidine is a new alpha2-adrenergic receptor agonist with potentially useful characteristics for anesthesia. This comparative study aimed at evaluating the effects of dexmedetomidine on propofol requirements and cardiovascular/respiratory stability during plastic surgery sedation under local anesthesia. ⋯ Dexmedetomidine/propofol association for sedation is safe and has the following advantages: decrease in propofol requirements, cardiovascular stability, good perioperative bleeding control, lack of significant effects on ventilation.

[Postoperative analgesia following orthopedic surgery: a study comparing perivascular lumbar plexus inguinal block with ropivacaine (3 in 1) and spinal anesthesia with morphine.].
Perivascular Lumbar plexus inguinal block, (3-in-1 block) has been used for postoperative analgesia. This study aimed at comparing postoperative analgesia of 3-in-1 block and spinal morphine in patients submitted to lower limb orthopedic surgeries (LL). ⋯ Postoperative analgesia induced by 3-in-1 blockade showed less side-effects as compared to spinal morphine with similar analgesia duration.

[Comparative study between 0.5% bupivacaine, 0.5% enantiomeric mixture of bupivacaine (S75-R25) and 0.75% ropivacaine, all associated to fentanyl, for epidural cesarean section anesthesia.].
Clinical trials with local anesthetic levo-enantiomers have shown higher safety due to lower cardiotoxicity. This study aimed at evaluating quality of anesthesia and maternal/fetal repercussions of 0.5% bupivacaine, enantiomeric 0.5% bupivacaine (S75-R25) and 0.75% ropivacaine, all associated to fentanyl, in epidural cesarean section anesthesia. ⋯ Enantiomeric mixture 0.5% bupivacaine (S75-R25) and 0.75% ropivacaine for epidural anesthesia have provided as good conditions as racemic 0.5% bupivacaine for the surgical act. Newborn repercussions have shown that all solutions were equally safe.

[Continuous epidural anesthesia with 0.2% ropivacaine associated to general anesthesia for upper abdominal surgery in children.].
Several anesthetic techniques have been proposed for different pediatric surgeries to promote postoperative analgesia, among other advantages. This study aimed at evaluating propofol infusion rate and postanesthetic recovery of children submitted to upper abdominal surgeries under epidural anesthesia with 0.2% ropivacaine associated to general anesthesia with propofol or propofol plus sufentanil. ⋯ Continuous thoracic epidural anesthesia with 0.2% ropivacaine (1.5 mg.kg-1) associated to propofol infusion provides effective and safe anesthesia for upper pediatric abdominal surgeries. Propofol infusion rate and sedation duration were decreased with the association of sufentanil.
