0.25% levo-bupivacaine for interscalene block during shoulder surgery. A survey on 20 patients.
Interscalene brachial plexus block (ISB) is an alternative procedure to general anaesthesia for shoulder surgery, and consents the anaesthetist to easily control postoperative pain that, indeed, is known to be intense and often requires strong analgesic administration. The introduction of regional anaesthesia for this type of surgery, contributed to the relief of acute postoperative pain occurring in the recovery room since the analgesic effects of block persist for several hours after surgery depending upon the selected drug. The aim of this study was to determine the effects of 40 ml of 0.25% levo-bupivacaine, a local anaesthetic derived from the racemic mixture of bupivacaine, on the speed of onset, quality and duration of ISB. ⋯ Levobupivacaine is a newly developed local anaesthetic derived from a bupivacaine racemic mixture from which the right isomer has been eliminated. Levo-bupivacaine, compared to racemic mixture, is acknowledged to be less cardiotoxic, faster at equal dosage, and ensures a longer analgesic interval. Zero point twenty-five percent concentration was preferred in this study in order to inject large volumes (40 ml) with a minimal anaesthetic amount (100 mg), resulting in short time for obtaining loss of sensibility, optimal intraoperative conditions and long lasting block with adequate postoperative analgesia.

Randomized Controlled Trial Clinical TrialWash-in and wash-out curves of sevoflurane and isoflurane in morbidly obese patients.
The aim of this prospective, randomized study is to compare sevoflurane and isoflurane pharmacokinetics in morbidly obese patients. ⋯ The results of this prospective, randomized study confirmed that sevoflurane provides more rapid wash-in and wash-out curves than isoflurane also in the morbid obese patient.

Randomized Controlled Trial Clinical Trial[Topical anesthesia for cataract surgery with phacoemulsification: lidocaine 2% vs ropivacaine 1%. Preliminary results].
The safety, tolerability and efficacy of ropivacaine 1% vs lidocaine 2% for phacoemulsification using topical anesthesia during cataract surgery, are compared. ⋯ Lidocaine 2% and ropivacaine 1% were safe and effective agents in patients having phacoemulsification with IOL implantation. However, ropivacaine provides more good operative conditions than lidocaine for the surgeon and comfortable surgical circumstances for the patient.

Case Reports[Endotracheal tube and trachebronchial obstruction due to a large blood clot. Case report].
A case of endotracheal tube and tracheobronchial acute obstruction caused by a large blood clot reproducing in part the trachea and the right bronchial tree is reported. The event has been anticipated by recurring hemoptyses whose source remained unknown despite any examination. ⋯ On the other side, those techniques should be used in case of obstruction located under the endotracheal tube. Albeit obstruction of endotracheal tubes due to blood clots is a frequent complication in critical care setting, this case is reported for the peculiar dimension and morphology of the clot, underlying that a precise diagnosis of the obstruction level allows the use of the most suitable technique for its removal.
