As diagnostic methods of detecting drug-specific IgE antibodies become more sophisticated, the evidence implicating specific IgE in anaesthetic allergy has increased. To implicate IgE in reactions, a history resembling anaphylaxis, the demonstration of drug-specific histamine release by intradermal testing and the demonstration of specific antibodies are necessary. Such evidence is seen in 70% of muscle relaxant reactors. Basophil histamine release studies suggest that histamine release is allergen-induced, not direct, and the final evidence necessary is to demonstrate the role of drug-specific antibodies in such histamine release.

Comparative Study[Is automatic oscillometric measurement of blood pressure reliable in hypotension?].
The reliability of an automatic oscillometric device for measurement of blood pressure (BP) was assessed in a large range of BP values during intraoperative normotension and induced hypotension. Direct BP measurements were carried out with a radial catheter. Data were compared with those obtained with the oscillometric device placed on the opposite arm. ⋯ When BP values lower than 90 mmHg (12 kPa) for Pasys, 60 mmHg (8 kPa) for Padia and 70 mmHg (9,3 kPa) for Pa were considered individually, the correlation coefficients were 0.83, 0.73 and 0.77 respectively. These findings suggested that the oscillometric method can be considered as relatively suitable for monitoring moderate hypotension induced by vasodilators. The invasive technique must however remain the method of choice during profound hypotension.
