Randomized Controlled Trial Clinical TrialEffects of remifentanil infusion bis-titrated on early recovery for obese outpatients undergoing laparoscopic cholecystectomy.
In obese patients functional residual capacity comes down with a possible hypoxemia in postoperative period. In fact many studies has been begun to determine optimum ventilation regulation and the best position for these patients, but the question has not been solved. As remifentanil can reduce of 50% the inhalatory anaesthetic request and reverse Trendelemburg position is extremely useful for these patients, we hypothesized that use of a continuous remifentanil infusion during balanced anaesthesia with sevoflurane, BIS-titrated, associated to reverse Trendelem-burg position could facilitate emergence from anaesthesia in obese patients undergoing laparascopic cholecystectomy. ⋯ Concluding, remifentanil infusion, BIS-titrated, facilitates awakening times from balanced anaesthesia with Sevoflurane in obese patients, submitted to laparoscopic cholecystectomy.

Randomized Controlled Trial Clinical TrialTwo doses of oral ketamine, given with midazolam, for premedication in children.
Oral premedication is common practice in paediatric anaesthesia. The aim of this study was to assess the quality of premedication using oral ketamine, with midazolam. ⋯ Two mgxkg-1 of ketamine given orally with midazolam improve anxiolysis and sedation and achieve more success of premedication, better acceptance of parental separation and better acceptance of face mask for induction of anaesthesia.

Randomized Controlled Trial Comparative Study Clinical TrialLevobupivacaina, bupivacaina racemica e ropivacaina nel blocco del plesso brachiale.
To compare clinical profiles of levobupivacaine, racemic bupivacaine and ropivacaine at equipotent doses in axillary brachial plexus block in the orthopaedic surgery of wrist and hand. ⋯ In our experience levobupivacaine has been demonstrated to be a good substitute for racemic bupivacaine. Compared to ropivacaine, levobupivacaine induces a longer duration of postsurgery analgesia and, in our opinion, this datum seems to be the most significant.

Steroids, drugs with potent antiinflammatory properties on the damaged nervous roots, have been especially used as adjuvants of local anesthetics, by spinal route, in the treatments of low-back pain. Spinal route was chosen to obtain a higher local concentration of drug, with few systemic side effects and to improve drug's action mechanism. Steroids seem to interact with GABA receptors and thus control neural excitability through a stabilising effect on membranes, modification of nervous conduction and membrane hyperpolarization, in supraspinal and spinal site. ⋯ Steroidal toxicity seems to be related to the polyethylenic glycole vehicle. Anyway, slow release formulations contain less concentrated polyethylenic glycole. The epidural administration, a correct dilution of steroid with local anesthetics solution and/or saline solution, and a limited number of injections (no more than three) allows a significant reduction of steroid neurotoxicity.
