Successful management with patient-controlled-analgesia using injectable oxycodone/hydrocotarnine compound for a 10-year-old boy suffering from severe abdominal pain caused by Churg-Strauss Syndrome: a case report

Abstract

Churg-Strauss syndrome (CSS) is characterized as systemic allergic granular angitis that shows a variety of cardiovascular, neurological, renal, and gastrointestinal symptoms. A 10-year-old boy suffering from severe abdominal pain with bilateral foot pain, pyrexia, bronchial asthma, eosinophilia, elevated C-reactive protein, and cardiomegaly caused by CSS was referred to our pain clinic. His severe abdominal pain had been palliated successfully by patient-controlled analgesia (PCA), using mixed oxycodone/hydrocotarnine solution. An approximate 4-month therapy has successfully introduced complete remission of his CSS, which enabled normal oral intake to be recovered. The dose of oxycodone had been gradually reduced, and its administration was finally stopped with no withdrawal symptoms. Mixed oxycodone/hydrocotarnine solution by the PCA system is an effective method of choice to alleviate abdominal pain caused by CSS.
