- Abstract: Objective To explore the effects of different sevoflurane elution methods on awakening quality and cognitive function of elderly obese patients undergoing hip joint replacement.Methods A total of 90 elderly obese patients underwent hip joint replacement under intravenous inhalation combined with general anesthesia and maintained anesthesia with sevoflurane during surgery were selected as the research subjects,and randomly divided into group A and group B,and sevoflurane was eluted by closed elution method and decreasing concentration elution method,respectively.The concentration of sevoflurane exhaled and cognitive function scores at different time points of patients between the two groups were compared,and the awakening quality and the occurrence of adverse reactions during the awakening period of patients between the two groups were compared.Results At the end of the surgery,the concentration of sevoflurane exhaled by patients in group B was significantly lower than that in group A(P<0.05),and the recovery time,awakening time,tracheal extubation time,and anesthesia recovery room stay time of patients in group B were significantly shorter than those in group A(P<0.05).The incidence of agitation during the awakening period of patients in group B was significantly lower than that in group A(P<0.05),and the cognitive function score at the time of 2 hours after awakening of patients in group A was significantly lower than that in group B(P<0.05).Conclusion For elderly obese patients undergoing hip joint replacement with intravenous inhalation combined with general anesthesia,sevoflurane can be eluted by decreasing concentration elution method before the end of surgery,and the patient wakes up smoothly and in a shorter time,with fewer adverse reactions and less impact on postoperative cognitive function.
