Title: Effect of dexmedetomidine complex with remifentanil in elderly patients with laparoscopic colon cancer resection
Abstract: Objective
To study the effect of dexmedetomidine complex with remifentanil in elderly patients with laparoscopic colon cancer resection.
Methods
80 cases of elderly patients with laparoscopic colon cancer resection were selected and divided into the study group and the control group with 40 patients in each group according to the random number table method.Two groups were induced conventionally,and intraoperative anesthesia maintained by remifentanil and sevoflurane.The study group were pumped dexmedetomidine 0.8μg/kg 10min before induction,then the doses reduced to 0.2μg·kg-1·h-1 for continuous pumping until to the end of surgery,while the control group was pumped the same dose 0.9%sodium chloride injection,then the heart rate(HR)and mean arterial pressure (MAP)of the two groups were compared when entered into surgery room(T0),administered 5min(T1),after intubation(T2),surgical incision(T3)and after extubation(T4),and the compose score,recovery time,and agitation score of two groups were compared.
Results
HR and MAP of the study group at T1,T2,T3 and T4 were(62.2± 1.1)times/min,(67.3±3.2)times/min,(69.2±2.3)times/min,(70.2±2.5)beats/min and(68.3±0.5)mm Hg, (70.1±0.9)mm Hg,(71.5±0.9)mm Hg,(68.2±1.9)mm Hg significantly lower than which of the control group(t=9.289,10.293,8.928,9.039,9.278,10.789,9.322,8.399,all P<0.05),and HR and MAP of the control group at T1,T 2,T 3 and T 4 were significantly higher than T0,the differences were statistically significant(t =8.928,9.892,8.387,8.927,9,783,9,073,9.039,7.938,all P<0.05);Compose score(4.2±1.3)points of the study group was significantly higher than(1.2±0.2)points of the control group,but the agitation score of the study group was(1.2±0.7)points,which was significantly lower than(2.9±1.5)points of the control group, the differences were statistically significant(t=9.38,8.379,all P<0.05).
Conclusion
Dexmedetomidine complex with remifentanil has a anesthetic good effect in elderly patients with laparoscopic colon cancer resection, and which can maintain the more stable hemodynamics.
