Abstract:
Objective:To evaluate the effect of gender on neuromuscular blockade of rocuronium in epileptics.Methods:Forty American Society of Anesthesiologists physical status Ⅱ or Ⅲ patients, aged 18-59 yr, with body mass index of 18.5-24.0 kg/m 2, scheduled for elective surgery for treatment of epilepsy under general anesthesia, were divided into 2 groups ( n=20 each) according to gender: male group (group M) and female group (group F). Neuromuscular conduction function was monitored with a muscle relaxation monitor.Ulnar nerve was stimulated in TOF mode (frequency 2 Hz, wave width 0.2 ms, stimulation current 70 mA and interval 12 s). Rocuronium 0.8 mg/kg was injected intravenously during anesthesia induction, and endotracheal intubation was performed when T l reached maximum inhibition.The conditions of endotracheal intubation were evaluated by the modified method.When T 1 recovered to 25% during operation, rocuronium 0.15 mg/kg was intravenously injected.Sugammadex sodium 2 mg/kg was injected intravenously when T 1 recovered to 50% after surgery.The onset time (T onset), peak time (T peak), 10% recovery time (T 10%), 10%-25% recovery time (T 10%-25%), 25%-50% recovery time (T 25%-50%), 50%-75% recovery time (T 50%-75%) and 75%-90% recovery time (T 75%-90%) of rocuronium were recorded.Peripheral venous blood samples (3 ml) were collected when T 1 recovered to 25% and 75%, and the concentration of rocuronium was detected by liquid chromatography-tandem mass spectrum.The consumption of rocuronium per unit of weight per minute was calculated. Results:There was no significant difference between the two groups in terms of T onset, T peak, T 10%, T 10%-25%, T 25%-50%, T 50%-75%, T 75%-90%, endotracheal intubation conditions, blood concentration of rocuronium at varied time points, or consumption of rocuronium per unit of weight per minute ( P>0.05). Conclusion:Gender exerts no effect on the neuromuscular blockade of rocuronium in epileptics.
