[¿Anafilaxia perioperatoria? Serie de casos].

OBJECTIVE

Identify the causative agent of POH, to avoid re-exposure and assess the use of alternative treatment.

METHODS

10 cases of immediate POH are described, in all of them a history of previous surgical procedures, carrying out a 3-step protocol: 1st documenting the surgical record to identify exposures, 2nd performing skin and/or epicutaneous tests and 3rd searching for an alternative treatment. treatment if a new surgical procedure is required and in selected cases challenge tests.

RESULTS

Of a total of 10 patients with immediate POH, tests were performed according to the case: neuromuscular blockers, anesthetics, opioids, NSAIDs, anti- biotics, diuretics, latex, isodine, and chlorhexidine; finding positive tests in 7 (70%) patients: in 4 (40%) neuromuscular blockers, one of them also positive for latex, in 2 (20%) anesthetics and finally finding a pharmacological alternative in 2 (2%) and recommending free operating room latex in 2 cases (20%), the rest (30%) were classified as related to the surgical procedure and medication management.

CONCLUSIONS

The study of POH is focused on ensuring safety in subsequent exposures, so in addition to identifying the causative agent, the role of the allergist also leads to a search for a safe alternative in patient management.
