[Neuromuscular block control during and after anaesthesia (author's transl)].

During many years the clinician's requirements for neuromuscular blocking drugs are satisfied by clinical investigations. Electromyographic recordings which are a satisfactory method are not useful in current practice. The use of nerve stimulators as Churchill Davidson apparatus modified for train of four impulses must reach the continental theatres, the response to neuromuscular blocking agents varying over a wide range. Five ways of stimulation can be used giving different informations, not only during anaesthesia, but so after particularly to specify the origin of some complications.
