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[Atracurium and cirrhosis: clinical study of the curariform action].
Hepatic function influences the action of muscle relaxants. Among these drugs, the elimination of atracurium does not depend on liver function. The clinical effects of atracurium were studied in ten patients with portal hypertension and some degree of liver dysfunction and in ten normal patients. ⋯ No statistically significant differences were observed. It is suggested that non significant differences observed could be attributed to an increased volume of distribution of drugs in the cirrhotic patient. These results would suggest that atracurium may be the best relaxant in patients with severe liver failure.

Comparative Study[Course of the neuromuscular block under atracurium. Comparison with alcuronium].
Using a standardized anaesthetic protocol, the continuous monitoring of the twitch height after a 0.1 Hz stimulus was used to follow the evolution of curarization following injection of either atracurium (0.6 mg . kg-1) or alcuronium (0.2 mg . kg-1). The maximum twitch height inhibition was always greater than 99% of the control value and occurred after 107 +/- 50 s with atracurium (n = 30) and 172 +/- 120 s for alcuronium (n = 30) (p less than 0.02). ⋯ The spontaneous return to normal of the train of four was also significantly longer (p less than 0.001) for alcuronium: 118 +/- 23 min (n = 10) versus 69 +/- 7 min for atracurium (n = 10). The recovery index (the time required for twitch height to rise from 25% to 75%) was three times quicker (p less than 0.01) for atracurium (10 +/- 3 min; n = 10) than for alcuronium (30 +/- 13 min; n = 10).(ABSTRACT TRUNCATED AT 250 WORDS)
