[High-risk factors in anesthesiology and methods of detection].

: This study demonstrates the importance of allergies to drugs used in premedication and enables one to realize the practical difficulty in picking out the causal drug allergies in anaesthetic accidents. From the practical point of view, it is evidently impossible to carry out L.T.T.s in all patients, considered as being exposed to an allergic risk in anaesthesia. It could however be envisaged carrying out ingestion tests such as are used in order to demonstrate intolerance to iodine, by the administration of small doses of Lugol's iodine or tablets containing iodine, and which lead to benign digestive intolerance reactions.
