The Impact of Dexmedetomidine-assisted General Anesthesia on Hemodynamics in Patients Undergoing Pulmonary Lobectomy
Objective To investigate the impact of dexmedetomidine-assisted general anesthesia on hemodynamics in patients undergoing pulmonary lobectomy.Methods Sixty patients who underwent pulmonary lobectomy in Xuchang People's Hospital from May 2022 to December 2023 were selected as the research subjects.They were randomly divided into a control group and an observation group,with 30 cases in each group.The control group received conventional general anesthesia,while the observation group received dexmedetomidine-assisted general anesthesia.The changes in hemodynamic indices at different time periods,the incidence of complications,the incidence of adverse reactions,the amount of anesthetic used,and the number of uses of vasoactive drugs were compared between the two groups.Results The heart rate and mean arterial pressure of the observation group were lower than those of the control group at the perioperative period,the completion stage of the operation,and 30 minutes after the operation,and the blood oxygen saturation was higher than that of the control group at the same time period,with statistically significant differences(P＜0.05).The incidence of adverse reactions and complications in the observation group was lower than that in the control group,with statistically significant differences(P＜0.05).The number of uses of vasoactive drugs in the observation group was significantly less than that in the control group,and the amount of anesthetic used was lower than that in the control group,with statistically significant differences(P＜0.05).Conclusion By adopting dexmedetomidine-assisted general anesthesia,the impact on hemodynamics in patients undergoing pulmonary lobectomy is small,effectively reducing the amount of anesthetic and complications,and is worth clinical application.
