Effect of remimazolam tosylate on hemodynamics during the induction of general anesthesia in the elderly / 局解手术学杂志

ABSTRACT

Objective To investigate the effect of rimimazolam tosylate on hemodynamics during the induction of general anesthesia in elderly patients.Methods A total of 90 elderly patients who received non-cardiac surgery under tracheal intubation general anesthesia in our hospital were selected,and randomly divided into the remimazolam tosylate group(group R)and the etomidate group(group E).During anesthesia induction,patients in the group R were given 0.3 mg/kg of remimazolam tosylate,and patients in the group E were given 0.3 mg/kg of etomidate.The heart rate(HR),mean arterial pressure(MAP),and bispectral index(BIS)before the induction of anesthesia(T0),after the induction of anesthesia(T1),and after tracheal intubation(T2)of patients in the two groups were compared.The induction time,extubation time,Ramsay sedation score 5 minutes after extubation,time out of the postanesthesia care unit(PACU),operation time,anesthesia time and incidence of adverse reactions in the two groups were counted.Results There was no significant difference in the MAP,HR or BIS of patients at T0 between the two groups(P>0.05);the MAP of patients at T1 and T2 in the group R were higher than those in the group E(P<0.05),and the HR of patients at T2 was lower than that in the group E(P<0.05).Compared with T0,the HR,MAP and BIS of patients at T1 and T2 in the group R were decreased;the MAP and BIS of patients at T1 and T2 in the group E were decreased,HR of patients was decreased at T1 and increased at T2,with statistically significant differences(P<0.05).The induction time and extubation time of patients in the group R were shorter than those in the group E(P<0.05).There was no significant difference in the Ramsay sedation score,time out of the PACU,operation time oranesthesia time of patients between the two groups(P>0.05).The incidences of myoclonus and hypotension of patients in the group E were higher than those in the group R,and the total incidence of adverse reactions in the group E was higher than that in the group R,with statistically significant differences(P<0.05).Conclusion Compared to etomidate,remazolam tosylate is more stable in inducing hemodynamics and has fewer adverse reactions in elderly patients under general anesthesia.
