Background: Intravenous regional anesthesia is a technique developed by the use of tourniquet and intravenous injection of anesthetic drug in the distal areas of the surgical region of the limbs. The aim of this study was to compare the onset of anesthesia induced by two methods of lidocaine use in regional intravenous anesthesia of the upper extremity.Materials and Methods: This single-blind clinical trial study was performed on 40 patients who referred to Bohlool hospital in Gonabad for forearm surgery. Samples were randomly divided into two receiving 40 ml lidocaine 0.5% and 20 ml lidocaine 1%. The research tool was a Researcher-made checklist and a Visual Analoge Scale (VAS). Fisher's exact test, independent and pair t-test were used for data analysis at a significance level of less than 0.05.Results: The results showed that the interval between the injection of anesthesia until the start of complete anesthesia was significantly shorter in the 20 ml lidocaine 1% recipient group compared to the 40 ml lidocaine 0.5% recipient group (p0.05).Conclusion: Regional intravenous anesthesia is induced by 20 ml lidocaine 1% faster than 40 ml lidocaine 0.5%.Keywords: Lidocaine, Intravenous, Regional anesthesia, Upper extremity

Background and Purpose: Opioids are frequently added to local anesthetics in order to improve analgesia in neuraxial blocks which may lead to – sometimes intolerable - pruritus in the patients. In this study the effect of meperidine on pruritus following the preh1ion of opioids (in the scale and dose of mg) in regional anesthesia was investigated. Methods and Materials: This clinical trial was conducted on 54 patients in two groups of 27. The patients included those hospitalized fro cesarean section in the midwifery ward as well as those in the surgical-orthopedic ward. Both groups received anesthetic and opioids (meperidine in mg doses). The first group i.e. the control group received a certain volume of physiologic serum and the second group i.e. the experimental group received the same volume of physiologic serum plus IV meperidine (nanogram dose). Pruritus was measured in the conventional scale at hours 0 6 12 and 24 after surgery. In the statistical analysis Mann Whitney U Fisher's exact test and chi-square were used. Results: in the experimental group incidence and intensity of pruritus (in case of occurring) were significantly lower than the control group (intensity score being one). Conclusion: Using nano-doses of opioids (meperidine) is effective in preventing pruritus.
