Treatment of perioperative anaphylaxis: room for improvement?
Perioperative anaphylaxis is associated with significant morbidity and mortality. Prompt and appropriate treatment is required for optimal outcome. Despite general knowledge of this condition, delays occur in the administration of epinephrine and in particular the use of i.v. route of administration in the perioperative setting. Barriers should be addressed to allow prompt utilisation of i.v. epinephrine in perioperative anaphylaxis.

Although sex differences in anaesthetic sensitivity have been reported, what underlies these differences is unknown. In rodents, one source of variability in females is the oestrous cycle. Here we test the hypothesis that the oestrous cycle impacts emergence from general anaesthesia. ⋯ In female rats, the oestrous cycle significantly impacts emergence from dexmedetomidine-induced unconsciousness. However, 17β-oestradiol and progesterone serum concentrations do not correlate with the observed changes.
