Effect of preoperative cognitive intervention on the inhibition of the emergence agitation of the elderly surgical patients with oral malignant tumors after anesthesia

Abstract

Objective To explore the effect of the preoperative cognitive intervention on inhibiting the occurrence of the emergence agitation of the elderly surgical patients with oral malignant tumors after anesthesia. Methods Eighty elderly surgical patients with oral malignant tumors were randomly divided into the control group and the intervention group. There were 40 cases in each group. The patients in the control group were given the routine oral malignant tumor surgery preparation and the anesthesia surgery nursing. The patients in the intervention group were given the preoperative cognitive intervention on the basis of the routine nursing. The incidence and the duration of the emergence agitation of the patients in the two groups were observed. The agitation degree was evaluated according to Riker Agitation-sedation Scale (RSS) . Results After the patients returned to the wards, the agitation happened to six patients in the control group, with the incidence rate of 15% (6/40) . The agitation happened to two patients in the intervention group, with the incidence rate of 5% (2/40) .The difference between the two groups was significant (χ2=6.274, P<0.05) . The average agitation duration in the control group was (7.67 ±1.23) min, which was significantly different from that in the intervention group (3.42±1.17) min (t=4.136, P<0.05) . According to the RSS evaluation, the agitation degree of the patients in the intervention group was slightly lower than that in the control group, and the difference was significant (χ2=3.253, P<0.05) . Conclusions The preoperative cognitive intervention in the elderly surgical patients with oral malignant tumors can significantly reduce the occurrence of the emergence agitation after general anesthesia.
