  • Influence of Propofol and Sevoflurane on the Mivacurium Chloride-induced Histamine Release

    ObjectiveTo explore the influence of propofol as well as sevoflurane on the histamine release induced by mivacurium chloride. MethodsForty patients with American Sociaty of Anesthesiologists stage Ⅰ-Ⅱ scheduled to receive ear-nose-throat surgery between March and October 2012 were recruited and were randomly assigned into two groups:propofol group and sevoflurane group. Patients in the propofol group were induced with targeted intravenous infusion with propofol. Patients in the sevoflurane group was induced with sevoflurane. The blood specimen was prepared before mivacurium chloride (0.16 mg/kg) infusion (T0), 1 minute (T1), 3 minutes (T2), and 5 minutes (T3) after the infusion. Mean blood pressure (MBP) and heart rate (HR) were recorded at corresponding time points. In addition, we recorded the symptoms of anaphylactic reaction such as skin erythema or bronchospasm. ResultsBoth MBP and HR decreased after anesthesia induction. However, there was no significant difference from that before the induction in both groups, and no difference was found between the two groups (P>0.05). The concentration of histamine in both groups at T1 and T2 was significantly higher than that at T0 (P<0.05). The concentration of histamine in both groups at T4 was significantly higher than that at T0 (P<0.05). The concentration of histamine in the propofol group was higher than that in the sevoflurane group. No skin erythema or bronchospasm was found in any of the two groups. ConclusionMivacurium chloride at a dose of 0.16 mg/kg can be safely used in propofol anesthesia, as well as sevofluane anesthesia, with no clinically significant histamine release or adverse hemodynamic fluctuation.
