Reporting Groups
Intrathecal Clonidine

Subject will receive one time Clonidine injection via lower lumber interspace. Clonidine (Duraclon), 100 μg/ml, 1.5 ml will be diluted to 2 ml with preservative free saline, and total of 150 μg will be delivered. Supine and sitting blood pressures and heart rate will be measured at 10 minute intervals until 60 minutes after clonidine administration, then at 15 minutes for next 3 hours.

  Outcome Measures

1.  Primary:   Change in Blood Pressure After Intrathecal Injection of Clonidine.   [ Time Frame: Baseline, Every 10 Minutes for first hour after clonidine injection, and every 15 minutes after first hour, until 4 hours after clonidine injection ]

2.  Secondary:   Likert Scale Pain Rating   [ Time Frame: Pre-dose and 1 hour post injection. ]

3.  Secondary:   Changes in Visual Analogue Scale (VAS) Ratings of Sedation and Sensation of Dry Mouth Reported by the Subjects, Pre and 1 Hour Post Injection   [ Time Frame: Before clonidine injection (Baseline), and at 1 hour after clonidine injection. ]

  Serious Adverse Events

  Limitations and Caveats

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
