title: [A new technic for interpleural blockade].
abstract: A new method for pleural block is presented. As the loss-of-resistance technique is not a useful approach for identification of the pleural cavity, alternative concepts, such as low-friction syringe-piston movement and infusion techniques have been developed for identification of the pleural cavity for catheter insertion. Both methods have the disadvantage that they involve a risk of pneumothorax during the insertion of the catheter, because it is necessary to disconnect the Tuohy needle from the syringe or infusion apparatus at the moment of catheter insertion. At this time there will be a direct communication between the pleural cavity and outside. A new technique has now been developed: this involves a latex balloon that collapses under the negative pressure of the pleural cavity. With this new technique it is possible to insert the catheter without disconnection. Furthermore, the identification is more sensitive than with the other techniques, so that the risk of pneumothorax is minimized. The technique has been applied in 71 cases with no technique-related complications.
