[Show abstract][Hide abstract] ABSTRACT: Infraclavicular brachial plexus block were first described by Raj, yet this block remained underutilized despite theoretical advantages. The aim of this prospective, randomized study was to compare equipotent doses of levobupivacaine and ropivacaine.
For this prospective, randomized study we have enrolled, after informed consent, 30 patients of both sexes, ASA status I-II, who were going to receive surgery to the forearm or hand with tourniquet position on the arm. The infraclavicular plexus block was performed by using vertical technique. The block was performed with 30 mL of levobupivacaine 0.5% or ropivacaine 0.75%.
No differences were reported between 2 groups in terms of demographic data. The onset-time for motor block was greater for ropivacaine group (p<0.05); the sensitive block was longer in levobupivacaine group (p<0.05).
The long duration of sensory block associated with the with good analgesia, less toxicity and the pharmacodynamic properties of levobupivacaine include this new local anaesthetic as a valid choice respect other local anaesthetic for infraclavicular plexus block.

[Show abstract][Hide abstract] ABSTRACT: The aim of this study was to compare the clinical profiles of psoas block and sciatic nerve block performed with either 0.5% levobupivacaine or 0.75% ropivacaine.
With ethical committee approval and written informed consent 80 ASA physical status I-II patients, undergoing lower extremity surgery received intravenous premedication with midazolam (0.05 mg/kg) and atropine (0.01 mg/kg). Patients were randomly allocated to receive a lumbar plexus block with: Levobupivacaine Group (L) 30 ml of 0.5% levobupivacaine or Ropivacaine Group (R) 0.75% ropivacaine, and sciatic nerve block with: Group R 10 ml 0.75 ropivacaine or Group L 0.5% levobupivacaine. The onset time and duration of nerve block were evaluated.
The motor onset time was shorter in Group L than in Group R. The motor offset time was similar in the 2 groups, the time being slightly greater for Group R. Group L presented a higher difference of resolution to motor-sensitive block compared to Group R.
The differences between Groups L and R were characterised by: a faster motor onset time in Group L with a longer time between motor and sensitive resolution determining a lower demand for analgesic drugs postoperatively and greater support for motor control recovery.

[Show abstract][Hide abstract] ABSTRACT: The option of analgesic anaesthesia without hypnotic was investigated in 13 patients, submitted to general, orthopedic or urologic surgery. Induction and maintenance of anaesthesia was performed with syringe-pump infusion of remifentanil 1-->2.2 mcg/kg/m and cisatrecurium, 0.2/air with FIO2 0.3; ecg monitoring, sieric level of ACTH were studied. "Slipping 8 channels patterns" were observed without spindless and K complexes; only in 2 patients N2O 50% can be used for increasing the depth of narcosys; ACTH levels increases only after remifentanil infusion stop.
