| Measure | Time frame |
|---|---|
| Main Objective: To determine the frequency of positive skin testing in subjects that exhibit no evidence of anaphylaxis following the administration of neuromuscular blocking drugs.;Secondary Objective: i) To determine the frequency of chlorhexidine sensitization in the study group. ii) To determine the frequency of sensitization to latex in the study group. iii) To determine the frequency of raised serum tryptase in the individuals that show evidence of positive skin testing. iv) To determine the frequency of cross-sensitization (ability of the immune system to recognize several drugs despite only being exposed to one previously) in the cohort. v) To determine the rate of sensitization to neuromuscular blocking drugs 3 days after administration. vi) To determine any correlation between Total IgE and sensitization in the study group. ;Primary end point(s): The frequency of positive skin testing in subjects that exhibit no evidence of anaphylaxis following the administration of neuromuscular blocking drugs. | — |
