Abstract Objective To explore the application of entropy index monitoring for general anesthesia in the elderly patients underwent abdominal surgery.Methods A total of 60 elderly patients underwent elective abdominal surgery under general anesthesia who were admitted to our hospital from February 2018 to October 2019 were selected as the research objects,and they were divided into group E(n=30)and Group C(n=30)according to random number table method.Group E adjusted Remifentanil and Sevoflurane according to entropy index, group C adjusted Remifentanil and Sevoflurane according to blood pressure and heart rate (HR).The systolic blood pressure (SBP), diastolic blood pressure(DBP), HR at the time before anesthesia (T0), before induction (T1), after induction (T2), during skin incision (T3), after extubation (T4), the dosage of Remifentanil, the average inhalation concentration of Sevoflurane, the time of spontaneous breathing, eye opening, extubation, satisfaction scores , adverse reaction were compared between the two groups.Results The SBP, DBP and HR of group E at T1 were lower than those at T0, the differences were statistically significant(P＜0.05).The SBP, DBP and HR in group C at T1 were lower than at T0, the SBP, DBP and HR in group C at T3 and T4 were higher than those at T0, the differences were statistically significant (P＜0.05).The SBP, DBP and HR of group E at T1 were higher than those of group C, the SBP, DBP and HR of group E at T3 and T4 were lower than those of group C, the differences were statistically significant (P＜0.05).There were no significant differences in SBP, DBP, HR between T2, T3, T4 and T0 in group E (P＞0.05).There were no significant differences in SBP, DBP, HR between T0 and T2 in group C (P＞0.05).There were no significant differences in SBP, DBP and HR between the two groups at T2 (P＞0.05).The time of respiratory recovery, eye opening and extubation in Group E were shorter than those in group C, the dosage of anesthetics in Group E was less than that in group C, and the satisfaction rate in Group E was higher than that in group C, the differences were statistically significant (P＜0.05).The incidence rates of nausea, hypotension, restlessness and cognitive impairment in Group E were lower than those in group C, the differences were statistically significant (P＜0.05).There were no significant differences in the incidence of vomiting, intraoperative awareness, bradycardia and respiratory depression between the two groups (P＞0.05).The total incidence of adverse reactions in Group E was lower than that in group C, the difference was statistically significant (P＜0.05).Conclusion Application of entropy index monitoring in the elderly patients underwent abdominal surgery with general anesthesia can improve the anesthesia quality and save the anesthesia cost.
