[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.

[Exercise-induced rhabdomyolysis and risk for malignant hyperthermia: case report.].
Rhabdomyolysis is a skeletal muscle injury with cell components' release to plasma. Exhaustive exercise, especially in non-conditioned individuals, may result in severe morbidity such as hyperkalemia, metabolic acidosis, disseminated intravascular coagulation, acute respiratory distress syndrome and rhabdomyolysis. It has been suggested that malignant hyperthermia, thermal shock and exercise-induced rhabdomyolysis are closely related syndromes. This report aimed at describing a case of fatal rhabdomyolysis after physical exercise and its correlation with malignant hyperthermia. ⋯ It has been suggested that malignant hyperthermia and exercise-induced rhabdomyolysis are closely related syndromes. Patient died before any specific investigation of malignant hyperthermia, but it is important to look for susceptibility for this syndrome within the family to avoid potentially life-threatening anesthetic events.

[Total intravenous anesthesia for thymectomy in a Myasthenia Gravis patient: case report.].
Patients with neuromuscular diseases, as Myasthenia Gravis, react abnormally to anesthetics, depending on the technique and on the drugs. This report aimed at showing a case of Myasthenia Gravis patient submitted to thymectomy under total intravenous anesthesia with propofol and remifentanil. ⋯ Total intravenous anesthesia, with short-lasting anesthetics without active metabolites has favored recovery and early extubation of a Myasthenia Gravis patient submitted to thymectomy.
