[Effects of spinal administration of large volumes of 2% lidocaine and 1% ropivacaine on spinal cord and meninges: experimental study in dogs].
Spinal injection of large local anesthetic volumes after accidental dural puncture is an epidural anesthesia complication. This study aimed at investigating potential clinical and histological changes triggered by large volumes of 2% lidocaine or 1% ropivacaine in a simulated accidental spinal injection in dogs. ⋯ Large volumes of 2% lidocaine have determined more intensive clinical and histological changes as compared to 1% ropivacaine.

Duchennes Muscular Dystrophy is an X-linked recessive disorder, generally diagnosed in childhood, which progressively worsens to degenerate respiratory function. This report aimed at presenting the case of a patient with Duchennes Muscular Dystrophy diagnosed 2 years before, submitted to postectomy under general anesthesia with ketamine S. ⋯ Very careful pre-anesthetic evaluation, adequate monitoring and drugs not predisposing to complications make surgery and postoperative period safe for Duchennes Muscular Dystrophy patients.

[Processed electroencephalogram in children anesthetized with sevoflurane. Is it feasible?].
EEG-derived bispectral index (BIS), has been indicated as a major substrate for measuring hypnotic effects of anesthetic drugs. However, there are only limited data on the use of EEG in anesthetized children. This study aimed at evaluating changes in BIS, SEF95%, relative delta band frequency amplitude (d%) and suppression rate (SR) in children, correlating these changes with sevoflurane pharmacodynamic variables (EC and EC/MAC) as compared to adults. ⋯ Unlike d%, the variations of which seem brain maturation-related, BIS and SEF95% may be used to monitor sevofluranes anesthetic depth in children aged 0 to 12 years, observing the parameters suggested for adults.

[Comparative study of intercostal and interpleural block for post-cholecystectomy analgesia].
Postoperative analgesia is a wish of all surgical patients and has been used by most anesthesiologists. In addition to opioids, local anesthetic agents have been employed for peripheral and central blocks. The purpose of this study was to evaluate and to compare intercostal and interpleural blocks for post-cholecystectomy analgesia. ⋯ We concluded that both techniques were effective in promoting post-cholecystectomy analgesia, but interpleural block was easier to perform.

[Spinal anesthesia for cesarean section with 0.5% isobaric bupivacaine plus fentanyl and morphine: prospective study with different volumes].
Spinal block for cesarean section was described few years after the first report of spinal anesthesia by Bier in 1899. It was not until the last 5 years that spinal anesthesia has become the most frequent anesthetic method for cesarean section at our hospital. This prospective study aimed at evaluating 0.5% spinal isobaric bupivacaine for cesarean section, injected after fentanyl and morphine, in the lateral position, and at correlating the incidence of hemodynamic changes and cephalad spread with different volumes. ⋯ Results of this study confirm that 0.5% isobaric bupivacaine, following fentanyl and morphine injected with separate syringes and in the lateral position, in doses of 2.5, 3 and 4 ml provides a fast and effective anesthesia for cesarean section.
