TRIAL DESCRIPTION
Public title A COMPARATIVE ANALYSIS OF THE EFFECTS OF INTRATHECAL DEXMEDETOMIDINE AND MORPHINE IN LOWER LIMB ORTHOPAEDIC SURGERY.
Official scientific title A COMPARATIVE ANALYSIS OF THE EFFECTS OF INTRATHECAL DEXMEDETOMIDINE AND MORPHINE IN LOWER LIMB ORTHOPAEDIC SURGERY.
Brief summary describing the background and objectives of the trial In our study, we would like to observe the effects of intrathecal Dexmedetomidine and low-dose intrathecal Morphine in patients undergoing lower limb orthopaedic surgery in order to compare their post-operative analgesic efficacy and their side effect profile. If Dexmedetomidine proves to be as effective as other studies have shown, with a better side effect profile as compared to morphine, it could improve our patient care at Dr George Mukhari Academic Hospital tremendously for our patients undergoing orthopaedic lower limb surgery.

OUTCOMES
Type of outcome Outcome Timepoint(s) at which outcome measured
Primary Outcome To compare side effects for both agents observed intra-operatively and post-operatively, which include:  Hypotension  Bradycardia  Respiratory depression  Pruritis  Nausea and vomiting INTRAOPERATIVELY AND POSTOPERATIVELY
Secondary Outcome  To compare the adequacy of post-operative pain control of both agents.  To compare the duration of post-operative pain control by evaluating time to first rescue analgesia in the ward.  To compare the onset time of spinal anaesthesia by evaluating time to reach dermatome level T10 for both agents.
