Abstract:
Objective To evaluate the effect of neoadjuvant chemotherapy factor on neuromuscular block induced by cisatracurium in the patients undergoing radical gastrectomy.Methods Sixty American Society of Anesthesiologists physical status Ⅰ or Ⅱ patients,aged 48-79 yr,with body mass index of 20-27 kg/m2,scheduled for elective laparoscopic radical gastrectomy,were divided into 2 groups (n =30each) according to whether the patient received neoadjuvant chemotherapy before operation or not:nonchemotherapy group (group A) and neoadjuvent chemotherapy group (group B).Anesthesia was induced with cisatracurium 0.15 mg/kg (3×ED95) injected intravenously.When T1 recovered to 10％ of control height,Ⅳ infusion of cisatracurium was started with an initial dose of 1.5 μg · kg-1 · min 1,and the infusion rate was adjusted with the amplitude of 0.2 μg · kg 1 · min-1 to maintain T1 at 5％-10％ of control height.The onset time,nonresponse time,time for T1 to recover to 10％,recovery index and time for train of four ratio to recover to 90％ were recorded.The consumption of cisatracurium was continuously recorded event 30 min starting from Ⅳ infusion of cisatracurium for 3 times,90 min in total.The mean infusion rate within 90 min was calculated.Results Compared with group A,the onset time,recovery index and time for train of four ratio to recover to 90％ were significantly prolonged,the nonresponse time and time for T1 to recover to 10％ were shortened,and the consumption of cisatracurium and mean infusion rate were increased in group B (P＜0.05).Conclusion Neoadjuvant chemotherapy factor can weaken neuromuscular block induced by cisatracurium in the patients undergoing radical gastrectomy.
