The research examines the pain-relieving effects and safety of clonidine hydrochloride, a medication that can help with pain control, sedation, and blood pressure management after major abdominal surgery.

The purpose of this research is to understand how a single dose of clonidine given through an intravenous injection affects post-surgical pain in patients who have had colectomy surgery. During the study, participants will receive either clonidine or placebo through an injection into their vein. The maximum daily dose of clonidine used in the study is 750 micrograms.

The study will monitor various aspects of patient recovery after surgery, including pain levels, vital signs (such as blood pressure and heart rate), and the amount of other pain medications needed. Blood samples will be collected to measure medication levels in the body. The treatment period lasts for one day after the surgery.
