Clinical use(s) of clonidine:
1. analgesic
2. antihypertensive
3. both
4. neither
Neuraxial use of clonidine: -- mechanism of analgesia

Use of preanesthetic clonidine (Catapres):
1. reduces intraoperative blood-pressure and heart rate lability
2. increases anesthetic requirements for inhaled and injected agents
3. increases likelihood of reflex tachycardia caused by direct laryngoscopy for tracheal intubation
