Case Reports[Prolonged neuromuscular block after administration of mivacurium caused by plasma psueudocholinesterase deficiency].
Mivacurium is a new neuromuscular blocking agent with a short acting time of about 30 min, due to a fast hydrolysis by pseudocholinesterases. This metabolism carries a risk for prolonged neuromuscular block in case of an acquired or congenital pseudocholinesterase deficiency. ⋯ L-1). The likely cause was a congenital deficiency by a homozygote genetic mutation, as usual causes of an acquired deficiency had been eliminated.

Randomized Controlled Trial Comparative Study Clinical Trial[Comparison of extrapleural and intrapleural analgesia with bupivacaine after thoracotomy].
To compare the analgesic and the ventilatory effects as well as blood concentrations of bupivacaine, administered either in the extrapleural or interpleural space after posterolateral thoracotomy. ⋯ Extrapleural administration of bupivacaine provides better analgesia as the anaesthetic agent comes in closer contact with intercostal nerves and with lower risk of loss of agent through the pleural drainage. Therefore its use is recommended preferentially over the interpleural route for analgesia after posterolateral thoracotomy.

[Ventilators for anesthesia. Models available in France. Criteria for choice].
This update article discusses the criteria for the choice of an anaesthetic machine and provides a short analysis of the main components of the models commercialized in France in 1994. The following items are considered: the design of the machine, the fresh gas delivery system, the anaesthesia breathing system(s), the ventilator and the waste gas scavenging system, the monitors associated with the machine and other criteria such as facility of learning to run the machine and of its daily use, ease of "in-house" maintenance and quality of after-sales service, cost of the machine and of its use (driving gas, disposable equipment).

Quantitative and qualitative nutritional requirements depend on the level of energetic expenses. Various formulas, especially the tables by Harris and Benedict allow the estimation of the level of energetic expenses with an approximation of 14%. Corrective factors permit an adjustment of the figures, according to the level of body aggression. ⋯ Biological monitoring includes the electrolyte balance and various variables of carbohydrate, lipidic and proteic metabolisms. It allows to check the absence of hyperglycaemia, hyperlipidaemia and cholestasis. The daily checking of catheters is part of the monitoring of nutritional support.(ABSTRACT TRUNCATED AT 250 WORDS)
