Protocol summary

Study aim
Comparison of intravenous propofol-remifentanil anesthesia and isoflurane inhalational anesthesia on QTc interval in patients receiving methadone maintenance therapy who are candidate for open limbs surgery
Design
Double blind randomized clinical trial, Sixty participants with inclusion criteria after justification and informed concern assign in intervention or control group.
Settings and conduct
This study performs in operation rooms of Imam Hossein Hospital, . Anesthesiologist and nurse anesthesia are aware of patient's group and record in questionnaire. Questionnaire has two portion (demographic and data recording portion) with identical cod. They seperate data recording portion and gives it to person who is responsible of outcome recording and is unaware of patient grouping.(syringes pump and isoflurane vaporizer have covers)Data analysig investigator is also unaware of patient's grouping.
Participants/Inclusion and exclusion criteria
Inclusion criteria: Male, Age 18 - 60 Methadone maintenance therapy with a dose of at over 50 mg per day Open limbs surgery under general anesthesia Class 1 and 2 of anesthesia risk Exclusion criteria: Use of every drug except methadone in last week Moderate and severe systemic disorders( anesthesia risk over 2) Every preoperative abnormal heart rate and rhythm. Need for injection of any drug out of study protocol
Intervention groups
Intervention group: Maintenance of anesthesia performs with Intravenous propofol-remifentanil (propofol 100 g / kg / min with remifentanil 1 microgram / kg / min) And the dose of the propofol will be adjusted based on the depth of anesthesia. Control group: Maintenance of anesthesia performs with inhalational isoflurane and intravenous remifentanil (1.2% isoflurane and 1 microgram/kg/min remifentanil).The dose of isoflurane will be adjusted based on the depth of anesthesia.
Main outcome variables
QT interval
