Review Case Reports[Venous catheterization and congenital abnormalities of the superior vena cava].
Persistent left superior vena cava is encountered in about 0.3 to 0.4% of human beings. It derives from remnants of the left cardinal vein system. This results in either a duplication of the superior vena cava or in a single left vena cava. ⋯ Diagnosis was easily provided by angiography. Clinical course was uneventful. Despite its usual good tolerance, the persistence of a left vena cava, as an isolated anomaly, must not be neglected as it carries many practical implications which are reviewed.

Regional anaesthesia has an important place in the management of elderly patients. Its selection depends on the type of surgery, the skills of the anaesthetist as well as the status and the will of the patient. Regional anaesthesia should no longer be considered as a challenger but rather as a complement to general anaesthesia, especially in the elderly.

Numerous anaesthetic techniques exist for a patient who presents with a difficult endotracheal intubation. They all require an anaesthetic protocol which cannot be improvised. ⋯ When a fiberoptic bronchoscope is not available, several alternatives can be suggested: local anaesthesia of the glottis, retro-molar and retrograde intubation, or the use of a guide threaded over a lighted stylet; these techniques can be used in an anaesthetized patient breathing spontaneously. In the paralyzed patient impossible to intubate, various trans-laryngeal techniques of ventilation can be used in emergency: jet ventilation via the trans-crico-thyroid route, the use of a cricotomy cannula, or a minitracheotomy set.

Review Multicenter Study Clinical Trial[Anesthetics responsible for anaphylactic shock. A French multicenter study].
Combined allergological and anaesthetic consultations have been started in the last few years in eight French Teaching Hospitals so as to explore peranaesthetic anaphylactoid shocks. A survey was carried out in these centers in order to collect patients investigated with the same protocol, for the assessment of the incidence of anaphylaxis in France, as well as the involved drugs. Investigations were always carried out at least 6 to 8 weeks after the accident. ⋯ It would therefore seem mandatory to carry out after any anaphylactoid accident an assessment with sensitive and specific tests for anaphylaxis. Diagnosing anaphylaxis means that the involved drug should be used never again in that patient. Because muscle relaxants are by far the most involved drugs, anaesthetists should use them only when really required.
