Abstract

Background and Objective: From 1942 when Griffith & Johnson suggested that muscle relaxants are safe drugs for better laryngoscopy & intubation and good for skeletal muscle relaxation during surgery, many of muscle relaxants discovered with different effect, side effect and potency. Some of the muscle relaxants properties include rapid onset, short-acting, fast recovery, stability of hemodynamic, lock of histamine release and etc. Hemodynamic stability is one of the important properties of this drug. In this research we wanted to see effect of Rocuronium, which is an intermediate muscle relaxant on systolic, diastolic BP and HR of patients who is candidate for elective surgery. Patients and Methods: This research is an experimental study. We wanted to see the effects of Rocuronium that is an intermediate muscle relaxant on mean avierial pressure and heart rate of the patient who is coming to the hospital of Iran medical university hospitals for elective orthopedic surgery. The sample size calculated 30 patients. We choose our patients with simple randomized method. All of them were ASA1 and in the age of 20 to 50 years old. The patients didn’t receive any pre-medication until coming to operating room. In the OR they received 7 cc/kg ringer solution and then 70 µg/kg thalamonal was administered intravenously. 5 minute latter their BP and PR was checked, which considered baseline measurement. Induction of anesthesia was with Thiopental 5 mg/kg and Rocuronium 0.9 mg/kg. After 60 sec patients were intubated with direct laryngoscopy. The maintenance of anesthesia for first 10 minutes was with O2 50% and N2O 50% and for continue of anesthesia MR and Opioid depend on need. Results: We analyzed our data with paired to T-test and green house test. Systolic and diastolic blood pressure and heart rate changes was 5% lowest than baseline hemodynamic parameter. Conclusion: With attention to previous studies and observation of hemodynamic changes with muscle relaxants which uses in Iran, this drug (Rocuronium) have good effect on stability of hemodynamic parameters. Beside other properties of Rocuronium include: Rapid onset, lack of histamine release, intermediate acting and etc. We can said this drug is a good and safe muscle relaxant for use during anesthesia and surgery.
