Brief summary
Objective: The present study was to evaluate the effects of dexmedetomidine alone, lidocaine alone and their combined infusion on postoperative inflammation cytokines after Laparoscopic hysterectomy. Methods: Investigators enrolled 160 women with American Society of Anesthesiologists (ASA) physical status I and II, aged 40-65 years, and scheduled for elective laparoscopic hysterectomy with general anesthesia from October 2017 to August 2018. The participants were randomly assigned into four groups(n=40 each group): group CON received normal saline infusion, group LIDO received lidocaine infusion (1.5 mg/kg loading, 1.5 mg/kg/h infusion), group DEX received dexmedetomidine infusion (0.5 µg/kg loading, 0.4 µg/kg/h infusion) and group LIDO+DEX received lidocaine (1.5 mg/kg loading, 1.5 mg/kg/h infusion) and dexmedetomidine infusions (0.5 µg/kg loading, 0.4 µg/kg/h infusion). The four groups received an IV bolus infusion of normal saline, lidocaine, dexmedetomidine and lidocaine combined with dexmedetomidine respectively, over 10 minutes before induction of anesthesia, followed by a continuous IV infusion of normal saline, lidocaine, dexmedetomidine and lidocaine combined with dexmedetomidine until abdominal wound closure, respectively. Interleukin-6 and tumor necrosis factor-α levels in serum were measured at different time points: before administration of drugs (T1), the end of surgery (T2), postoperative 2 hour (T3) and postoperative 24 hour (T4).
Interventions
Participants in the group CON were received normal saline infusion until 30 min before the end of the operation.Interleukin-6 and tumor necrosis factor-α levels in serum were measured at different time points: before administration of drugs (T1), at the end of the operation (T2), postoperative 2 hour (T3) and postoperative 24 hour (T4)
Participants in the group LIDO received lidocaine infusion (1.5 mg/kg loading, 1.5 mg/kg/h infusion)until 30 min before the end of the operation.Interleukin-6 and tumor necrosis factor-α levels in serum were measured at different time points: before administration of drugs (T1), at the end of the operation (T2), postoperative 2 hour (T3) and postoperative 24 hour (T4)
Participants in the group DEX received dexmedetomidine infusion (0.5 µg/kg loading, 0.4 µg/kg/h infusion) until 30 min before the end of the operation. Interleukin-6 and tumor necrosis factor-α levels in serum were measured at different time points: before administration of drugs (T1), at the end of the operation (T2), postoperative 2 hour (T3) and postoperative 24 hour (T4)
Participants in the group LIDO+DEX were received lidocaine (1.5 mg/kg loading, 1.5 mg/kg/h infusion) and dexmedetomidine infusion (0.5 μg/kg loading, 0.4 μg/kg/h infusion) until 30 min before the end of the operation, respectively. Interleukin-6 and tumor necrosis factor-α levels in serum were measured at different time points: before administration of drugs (T1), at the end of the operation (T2), postoperative 2 hour (T3) and postoperative 24 hour (T4)
