Analgesia Effect of Low-dose Ketamine Combined with Sufentanil after Radical Surgery of Esophageal Can-cer / 中国药房

ABSTRACT

OBJECTIVE:To investigate the analgesia effect of low-dose ketamine combined with sufentanil after radical sur-gery of esophageal cancer. METHODS:Totally 153 patients of pre-implementation esophageal cancer surgery were randomly divid-ed into group A,B and C. After induction of anesthesia in patients in each group,patients in group A administered sufentanil 2 μg/kg;group B were treated with sufentanil 2.5 μg/kg;group C were treated with sufentanil 2 μg/kg + ketamine 85 μg/(kg·h). Visual analog(VAS)score and Ramsay score before and after anesthesia 4,8,16,24 and 48 h,analgesia pump pressing times and inci-dence of adverse reactions in each group were observed. RESULTS:Ramsay score in 4,8 and 16 h in each group were significant-ly higher than before anesthesia,the differences were statistically significant(P<0.05),however,compared with before,there was no significant difference in the Ramsay score in 48 h among each group(P<0.05);VAS scores in each group(except for group C in 48 h) at each time point were significantly higher than before,group CAnalgesia pump pressing times in group Cincidence of adverse reactions in group C and group ACONCLUSIONS:Without reducing analgesic ef-fect,sufentanil combined with low-dose ketamine can reduce the dose of sufentanil for patients with anesthesia in radical surgery of esophageal cancer,with good safety.
