[Dexmedetomidine/propofol association for plastic surgery sedation during local anesthesia.].

Background And Objectives: Dexmedetomidine is a new alpha2-adrenergic receptor agonist with potentially useful characteristics for anesthesia. This comparative study aimed at evaluating the effects of dexmedetomidine on propofol requirements and cardiovascular/respiratory stability during plastic surgery sedation under local anesthesia.

Methods: Participated in this study 40 female patients aged 16 to 60 years, physical status ASA I or II, scheduled for elective face, nose and breast plastic surgeries under local anesthesia.

Thoracic epidural anesthesia with ropivacaine for plastic surgery.

Background And Objectives: Thoracic epidural blockade is a method of hypotensive anesthesia able to reduce bleeding during surgery. This non-comparative study aimed at evaluating the results of thoracic epidural blockade with 0.5% ropivacaine associated to propofol continuous infusion sedation in plastic surgery.

Intraocular pressure and ropivacaine in peribulbar block: a comparative study with bupivacaine.

Background: The aim of this study was to compare the effects on intraocular pressure (IOP) of ropivacaine and bupivacaine in peribulbar block.

Methods: The study involved 40 patients with ASA physical status I, II or III undergoing cataract surgery under peribulbar block. Patients were allocated to two groups according to the local anesthetic used: Group R (n=20), 1.

Ropivacaine in peribulbar block: a comparative study with bupivacaine.

Background: Ropivacaine is a new local anesthetic with alleged lower systemic toxicity and slightly lower potency as compared with bupivacaine. The present study aimed to evaluate the efficacy of ropivacaine in peribulbar block, as compared with that of bupivacaine.

Methods: Eighty patients aged 45-92 years with physical status ASA I, II, or III were randomized to Group R (n=40) or Group B (n=40).

[Comparative study of circulatory response to tracheal intubation with atracurium and succinylcholine].

Changes in some circulatory parameters after orotracheal intubation (OTI) were investigated in 40 patients anesthetized with thiopental 5.0 mg.kg-1 and fentanyl 100 micrograms, receiving either atracurium 0.
