Effect of oral clonidine on bleeding rate in lumbar laminectomy
Design
100 patients that meet the inclusion criteria after surgery finished and the patient is discharged from anesthesia will be selected as research sample and then divided into intervention and control groups with binary blocking.The intervention group will receive clonidine and the control group will receive placebo. The study is a randomized, double-blind,placebo-controlled clinical trial.
Settings and conduct
Patients will be randomly divided into two groups according to the random number table.The intervention group received 0.5 mg clonidine and the control group received the same amount of placebo half an hour before surgery. Given that the study is double-blind. Both clonidine and placebo medications will be prepared each morning by the number of surgeries and number required by the plan's administrator. Envelope A contains oral clonidine and envelope B is a placebo. Each patient will receive the envelopes based on whether they are A or B coded by an anesthetist who is blinded of the type of drug.Intraoperative bleeding will then be assessed according to the amount of suction device filling and the surgeon's satisfaction with the operative field bleeding.In this study patient and anesthesiologist is blinded.
Participants/Inclusion and exclusion criteria
Entry requirements:All ASA I & II class patients aged 18-60 years
Exclusion criteria:

Intervention groups
The intervention group received 0.2 mg clonidine orally with water and control group receive placebo similar to first group half an hour before starting of surgery.
Main outcome variables
The effect of clonidine on intraoperative hemorrhage by evaluation of suction device filling and field operation (low, moderate, high)

Randomization (investigator's opinion)
Randomized
Randomization description
In this study we use balanced randomization that at first four blocks with 9 combination will be formed and blocks will be numbered from 1to9. Compared to the simple randomization method, in this method the size of equilibrium of intervention and placebo groups will be established both during and at the end of study(randomization method is pre and post accidental blocks and will be done by randlist software)
Blinding (investigator's opinion)
Double blinded
Blinding description
The anesthesiologist who has responsible for the patients management of anesthesia will administer the medicine(s) via coded syringes had been prepared previously and will not aware of the injected drug(clonidine or pelacebo ), and anesthesia nurse who is responsible for collection of patients information and study variables and is unaware of the administered drug will record the check- list during surgery and in the recovery.Also the patient is unaware of the injected medicine.
