[Skin tests for general anesthetics].

During a meeting between anaesthetists and allergists, skin tests were presented to show their value and the difficulties to which they give rise when they are weak. General principles, techniques and readings are described first. As usual, it is sensitivity, specificity and negative predictive value that are at the centre of attention. Selected clinical cases are given as examples. The high prevalence of cases who show a latent sensitisation to curare indicates an increase in allergological tests to patients who present risk factors.
