Randomized Controlled Trial Comparative Study Clinical Trial[Cervical plexus block and continuous cervical peridural block with ropivacaine for carotid surgery: a comparison between the 2 methods].
To evaluate the efficacy and security of the cervical plexus block and the continuous cervical peridural anaesthesia in carotid surgery, using ropivacaine as local anaesthetic. ⋯ cervical plexus block and continuous cervical peridural anaesthesia performed with ropivacaine are both effective for anaesthesia in carotid surgery. Ropivacaine, for its minor cardiotoxicity, yields eventual complications related to the two methods, less severe.

The techniques of continuous peripheral blockades have shown to be efficient in postoperative pain control, in the various orthopaedic procedures of the limbs. The aim of this study is to evaluate the existing data about the use of a continuous blockade of the lumbar plexus or femoral nerve, together with the indications for technique and therapy. ⋯ The use of continuous blockades of the lumbar plexus or femoral nerve shows to be an important and effective instrument not only in terms of positive effects on postoperative pain control, but also in terms of relevant advantages concerning final outcome after surgery. Nevertheless these techniques should not be considered as the only approach to postoperative pain in the orthopaedic patient, but have to be included in a global, multidisciplinary and multimodal approach.

Randomized Controlled Trial Comparative Study Clinical Trial[S(-) bupivacaine (levobupivacaine) in peripheral blocks: preliminary results].
We have compared the onset time, anesthetic potency and adverse effects of three local anaesthetics (ropivacaine, levobupivacaine and bupivacaine) in two type of peripheral blocks (brachial plexus block for upper limb and femoral nerve block for lower limb) in adult patients in a double blind, randomized, prospective study. A total of 66 patients undergoing orthopaedic surgery were randomly allocated to receive brachial plexus block or femoral nerve blockade with 0,5% ropivacaine (group R, n=22), 0,5% levobupivacaine (group L, n=22) or 0,5% bupivacaine (group B, n=22), each groups has been divided into two subgroups (LBP n=11, RBP n=11, BPB n=11, LBF n=11, RBF n=11, BBF n=11) dipending on the type of block. The onset of sensory nerve block was similar for the three groups; the onset of motor block and onset time ready to surgery were faster in group R (-30%) if compared with group L and B. ⋯ We did not observe any adverse effect. We conclude that ropivacaine acts faster with less interpatient variability, while levobupivacaine and bupivacaine offer a prolonged postoperative analgesia. For this reason, with the exception of bupivacaine due to major cardio and neuro toxicity, we can indifferently use levobupivacaine or ropivacaine depending on the requested characteristics of the anesthetic.

Randomized Controlled Trial Comparative Study Clinical TrialHypertonic saline solution: a safe alternative to mannitol 18% in neurosurgery.
To evaluate the usefulness of hypertonic saline solutions (HTS) as an alternative to mannitol in neurosurgery. ⋯ HTS can safely be used in humans they obtain a reduction of ICP without reducing CVP, serum osmolality and Na+ serum values. Our data underline the possibility of their use as an alternative to mannitol in the treatment of patients scheduled for intracranial surgery, especially when multiple doses are needed.

Randomized Controlled Trial Clinical TrialImplementing sevoflurane anesthesia with small doses opioid for upper abdominal surgery. Postoperative respiratory function after either remifentanil or fentanyl.
The aim of this prospective, randomized study was to compare the effects on intraoperative cardiovascular homeostasis, recovery profile and postoperative oxygen saturation after sevoflurane anesthesia with small doses of either remifentanil or fentanyl in combination with postoperative epidural analgesia. ⋯ Implementing sevoflurane anesthesia with very small remifentanil infusion provides a safe and effective hemodynamic control reducing sevoflurane consumption during the procedure, and produces less respiratory effects postoperatively as compared with intermittent bolus administration of fentanyl.
