Abstract

Background: Adverse drug reactions (ADRs) are known to occur during anaesthesia; in the U.K. such ADRs may be reported through the Yellow Card Scheme (YCS). Our aim was to determine the demographics of ADRs to neuromuscular blocking drugs without formal causality assessment. Methods: A retrospective analysis of ADRs to seven neuromuscular blocking drugs reported via the YCS during a greater than 30‐year period was performed. Sex and age were analysed in order to identify at risk groups. Results: Of 998 reports, 969 included gender. Non‐allergic suspected reactions occurred with almost the same frequency as those with an allergic component. The majority occurred in females 676 (70%), and significant sex differences were measured between drugs. Males were more likely to have suffered an ADR to atracurium (p = 0.01) whilst females experienced more ADRs to suxamethonium (p = 0.01). ADRs proved fatal in 81 (9%) of the 950 reports for single drugs. Mortality following suxamethonium was significantly higher in males at 22% compared with 9% females (p < 0.001). More women than men were reported to have allergic reactions, 73% (362/499) compared with 27% (137/499) respectively. The female:male ratio for ADRs was reversed for subjects < 10 years compared with peak ADR reports during the decade from 31–40 years. Conclusions: Sex differences in mortality exist in this analysis. The unexpected high frequency of non‐allergic ADRs suggests that morbidity and mortality from reactions to established drugs is twice that expected from allergic reactions alone. Standards and guidance for the reporting of ADRs warrant urgent development. Copyright © 2006 John Wiley & Sons, Ltd.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
