Supraclavicular brachial plexus block: a comparative clinical study between bupivacaine and levobupivacaine.

Background And Objectives: Brachial plexus block is used in surgical procedures of the upper limbs. The brachial plexus is a potential territory for absorption of local anesthetics. Studies on bupivacaine isomers have shown reduced cardiovascular toxicity of its levorotatory form (levobupivacaine).

[The validity of the electrocardiogram accomplishment in the elderly surgical patient preoperative evaluation.].

Background And Objectives: Because of medical progress, life expectancy has been prolonged and the elderly population submitted to surgical procedures has been growing. Besides age-related cardiovascular changes, the prevalence of diseases, such as systemic hypertension, affect cardiovascular reserve and increase morbidity, mortality and perioperative outcomes. Electrocardiogram is useful in diagnosing previous myocardial infarction and arrhythmias.

[Intravenous isoflurane in lipid emulsion promotes cardiovascular and respiratory stability. Experimental model.].

Background And Objectives: Intravenous infusion of inhalation anesthetics may promote lung injury. Intravenous halothane in lipid emulsion induces anesthesia with hemodynamic and respiratory stability. This investigation aimed at establishing the induction dose of isoflurane in 10% lipid emulsion and at observing cardiovascular and respiratory effects in experimental anesthesia.
