Abstract:
Objective To investigate the effects of different depth of anesthesia on ScvO2 and ABL in elderly patients with gastrointestinal cancer. Methods Totally 55 elderly patients undergoing gastrointestinal sur-gery were randomly divided into deep anesthesia group(BIS40-49)(group D,n=27)and light anesthesia group (BIS50-59)(group S,n = 28). While SVV value was fixed,fluid management was conducted while monitoring CVP. HR,MAP,the change of central venous oxygen saturation and lactic acid index were recorded in different time points. Results Propofol dosage in group D and group S indicated statistical significance(P<0.05). ScvO2 in group S in T3~T5 was higher than that in T0 and the difference was statistically significant(P < 0.05). Com-pared with ScvO2 in T3 in group D,that in group S was significantly higher and the difference was statistically sig-nificant(P<0.01),but no significant difference was found in other time point in 2 groups(P>0.05). There was no significant difference between and within ABL groups in each time period(P>0.05). There was no significant difference in terms of other indicators between 2 groups. Conclusions For elderly patients with gastrointestinal surgery,shallow anesthesia can improve tissue oxygenation and reduce the amount of anesthetics.
