[Clinical evaluation of the single use Laryngeal Tube in adults: the LTD].
The Laryngeal Tube (LT) is a supra-laryngeal device indicated to manage upper airway during anaesthesia. Leak pressures were lately reported higher for the LT as compared to the LMA. A recent study found a small amount of proteinaceous material on LMA after classical sterilization suggesting a risk of contamination by unconventional transmissible agents (prions). The aim of this study was to evaluate the effectiveness of the single use Laryngeal Tube: the LTD. ⋯ the use of the LTD was easy and successful. Moreover the LTD totally excluded the risk of contamination by unconventional transmissible agents.

Despite the availability of modern neuromuscular blocking agents with short or intermediate duration of action, incidence of residual neuromuscular blockade remains very high. Evidences have been recently provided that residual curarization must be defined as a train-of-four ratio below 0.9 at the thumb adductor during the recovery period after anaesthesia. Residual curarization may be associated with serious adverse events related to respiratory depression, pharyngeal dysfunction, hypoxemia and prolongation of the length of stay in the recovery room. Appropriate choice of drugs, perioperative monitoring of neuromuscular function and large indications of pharmacological reversal may reduce the incidence of residual curarization and improve the patient's safety in the postoperative setting.

Case Reports[Postobstructif pulmonary oedema after endotracheal extubation at the recovery of general anaesthesia].
We report two cases of postobstructif pulmonary oedema occurring after extubation at the recovery of general anaesthesia and presenting some similarities. The young age of the patient and the occurrence of upper airway obstruction after extubation, as well as the radiologic nondependent distribution of alveolar pattern are typical. The underlying pathophysiology seems to be the mechanical disruption of the alveolar-capillary membrane.

Review[Premixed 50% nitrous oxide and oxygen: theoretical recalls and practical modalities].
The concept of premixed 50% nitrous oxide and oxygen dated back to 1961 in England, where it is commercialised under the name Entonox. In France, after a so marginal use, premixed 50% nitrous oxide and oxygen now knows such a revival since we first consider the pain provoked by the cure. To use correctly premixed 50% nitrous oxide and oxygen, we need to know the main properties of the nitrous oxide. ⋯ In less than 10% of the cases, side effects are possible. Conditions of administration are given in details. The limits of the technic and the particular precautions of use are precised.
