One hundred patients who received a competitive neuromuscular blocking agent during anaesthesia were randomly selected for evaluation of neuromuscular function immediately on their arrival in the recovery room. The anaesthetist was not aware that the patient would be evaluated in the recovery room. ⋯ Bedside tests of neuromuscular function did not reliably detect this defect in neuromuscular transmission. It is concluded that a relatively large number of patients have a defect in neuromuscular transmission on their arrival in the recovery room, and suggested that this reflects the inadequacy of clinical methods used for the administration and antagonism of competitive neuromuscular blocking agents at this institution.

Comparative StudyCutaneous sensitivity to atracurium and vecuronium in patients suffering anaphylactoid reactions to neuromuscular blockers.
Using an ordinal measure of cutaneous sensitivity to intradermal injections of atracurium and vecuronium, 40 nonreacting subjects were compared with a group of 24 patients previously suffering life-threatening anaphylactoid reactions to other muscle relaxants. Enhanced cutaneous sensitivity to vecuronium was found in three, and to atracurium in two of the previously reacting group. With the exception of those showing abnormal reactivity, no significant difference was found in the distribution of cutaneous sensitivity in the control and reacting group. A concentration of vecuronium 8.75 times that of atracurium was required to produce an equivalent intradermal wheal response.
