The PAIR function.

The PAIR function, which consists of percutaneous ambitiousness, introduction of protoscolicidal agents (e.g., 95% ethanol or 0.5% cetrimide), and reaspiration, has demonstrated efficacy as an alternative to medical procedure. A randomized, controlled attempt showed PAIR to be as effective as hospital room for hepatic cystic echinococcosis; moreover, patients treated with PAIR had lower postprocedure quality and a shorter medical building stay.121–123 Like hospital room, PAIR should be performed with albendazole therapy before and after the legal proceeding to minimize spread of any leaked fluids containing infectious protoscolices.124 PAIR is best used for internal organ cysts of 5 cm or greater that are anechoic, multiseptate, or multiple.113 The PAIR operation should not be performed if hepatic cysts communicate with the biliary treatise. Complications are more common when PAIR is used to victuals pulmonary lesions. PAIR may provoke acute allergic reactions.
