Clonidine Supression Test PROCEDURE NAME ____________________________________________________________________ REVIEW MODULE CHAPTER 76 ___________

Description of Procedure The clonidine suppression test is performed by taking a blood sample before the administration of clonidine. The clonidine is then administered and then three hours after the tests, the levels of adrenaline and noradrenaline are measured. No changes would indicate the presence of a pheochromocytoma.

Indications -Confirms a pheochromocytoma

CONSIDERATIONS

Nursing Interventions (pre, intra, post) -Pre-procedure: The nurse should insert a venous cannula and allow the client to rest 30 minutes prior to specimen collection. -Intra-procedure: A baseline specimen should be collected prior to administering clonidine. Once the clonidine is administered the specimen is to be collected 3 hours after. -Post-procedure: The nurse should continue monitoring BP for at least 1 hour after procedure.

Interpretation of Findings -If a client does not have a pheochromocytoma, clonidine supresses catecholamine release and decreases the blood level of catecholamines (decreases BP) -If a client has pheochromocytoma, clonidine has no effect on BP.

Potential Complications -Severe hypotension
