Analysis of Bis Monitoring in Geriatric Orthopedic General Anesthesia Surgery
Objective To investigate the application of Bispectral index(BIS)monitoring in elderly orthopedic surgery under general anesthesia.Methods A total of 90 cases of elderly patients who received orthopedic general anesthesia surgical treatment in Chenggong District People's Hospital from August 2022 to November 2023 were unrandomly se-lected and divided into two groups by difference anesthesia method.The study group(n=45)performed BIS monitoring to regulate anesthesia induction and maintenance medication,and the control group(n=45)routinely induced and maintained anesthesia.The two groups were compared in terms of the dose of anesthesia medication,postoperative re-covery indexes,changes in hemodynamic indexes[mean arterial pressure(MAP),heart rate(HR),arterial partial pres-sure of oxygen(Puise Oxygen Saturation,SpO2)]levels,and the occurrence of postoperative cognitive dysfunction.Results The dose of anesthesia medication and postoperative recovery indexes of the study group were better than those of the control group,and the differences were statistically significant(all P<0.05).The level of MAP and HR changes in the patients of the study group were more stable than those of the control group,and the differences were statistically significant(all P<0.05).There was no statistically significant difference in SpO2 levels between the two groups(all P>0.05).At 1 d and 3 d postoperatively,the incidence of postoperative cognitive dysfunction in the study group was 4.44%and 0,respectively,which were lower than those of the control group at 17.78%and 13.33%,and the differences were statistically significant(χ2=4.050,4.464,both P<0.05).Conclusion BIS monitoring reduces the dosage of anesthetic drugs in elderly orthopedic general anesthesia surgery patients,contributes to the quality of awak-ening and hemodynamic stability,and reduces the incidence of postoperative cognitive dysfunction.
