clonidine and Subarachnoid Hemorrhage

clonidine has been researched along with Subarachnoid Hemorrhage in 5 studies

Clonidine: An imidazoline sympatholytic agent that stimulates ALPHA-2 ADRENERGIC RECEPTORS and central IMIDAZOLINE RECEPTORS. It is commonly used in the management of HYPERTENSION.
clonidine (amino form) : A clonidine that is 4,5-dihydro-1H-imidazol-2-amine in which one of the amino hydrogens is replaced by a 2,6-dichlorophenyl group.

Subarachnoid Hemorrhage: Bleeding into the intracranial or spinal SUBARACHNOID SPACE, most resulting from INTRACRANIAL ANEURYSM rupture. It can occur after traumatic injuries (SUBARACHNOID HEMORRHAGE, TRAUMATIC). Clinical features include HEADACHE; NAUSEA; VOMITING, nuchal rigidity, variable neurological deficits and reduced mental status.

Trial Outcomes

Olfactory Dysfunction Outcomes Rating (ODOR)

"Participants will be asked to complete the ODOR, which is a patient-reported outcome measure assessing physical problems, functional limitations, and emotional consequences of olfactory dysfunction.~The ODOR has a minimum score of 0 and a maximum score of 112 with higher scores indicating a greater degree of impairment and limitation. The minimal clinically important difference is a change of 15 points." (NCT05445921)
Timeframe: baseline, 5-10 days post SGB #1, and 1 month

University of Pennsylvania Smell Identification Test (UPSIT)

"Participants will complete the 40-item scratch and sniff UPSIT and mean change will be assessed.~The UPSIT has a minimum score of 0 and maximum score of 40 with lower scores indicating a greater degree of impairment. An UPSIT score of >33 for men and >34 for women is considered normosmic, and the minimal clinically important difference is a change of 4 points." (NCT05445921)
