简要总结
The main objective of this study is to compare pholcodine exposure in patients having presented with a perianaesthetic anaphylactic reaction to a NMBA (cases) to pholcodine exposure in matched anaesthetised patients with injection of NMBA, who did not present with an anaphylactic reaction (controls).
The secondary objectives of the study are:
- To compare anti-pholcodine IgE, anti-ammonium IV IgE and total IgE levels between the case and control groups.
- To study the concordance between exposure to pholcodine in cases and controls, by means of a patient self-questionnaire on the one hand and, on the other hand, by a computerized drug history, supplemented where relevant by the drug master file.
- To study the impact of taking 1, 2 or 3 sources in account for pholcodine exposition.
- To study the association between exposure to pholcodine and the presence/levels of pholcodine-specific IgE, reflecting sensitisation to pholcodine.
- To study NMBA and pholcodine cross-sensitisation by testing skin reactions to pholcodine in case patients allergic to (at least) one NMBA.

结局指标
主要结局
Exposure to pholcodine
时间窗: within the 12 months before the anesthetic procedure
Exposure is measured by autoquestionnaire, patient's pharmaceutical file and drug history by the pharmacist's
次要结局
- Impact of non subjective sources in pholcodine exposure assessment(within the 12 months preceeding general anesthetic procedure)
- Anti-pholcodine IgE, anti-ammonium IV IgE and total IgE levels between the case and control groups.(Between 1 day to 12 weeks after the general anesthetic procedure)
- Concordance between exposure to pholcodine in cases and controls, by means of a patient self-questionnaire on the one hand and, on the other hand, by a computerized drug history, supplemented where relevant by the drug master file.(within the 12 months preceeding the general anesthesia)
- Association between exposure to pholcodine and the presence/levels of pholcodine-specific IgE, reflecting sensitisation to pholcodine.(within the 12 months preceding the general anesthetic procedure)
- NMBA and pholcodine cross-sensitisation by testing skin reactions to pholcodine in case patients allergic to one NMBA.(6 to 12 weeks after the general anesthetic procedure)
