Abstract:
Objective:To explore application value of combined spinal-epidural anesthesia under the assistant of ultrasound location on lower limb fractures.Methods:A total of 80 patients with lower limb fractures who underwent surgical treatment at the 901th Hospital of the PLA Joint Service Support Force from July 2020 to July 2022 were selected,and they were divided into a control group and an observation group according to the random number table method,with 40 cases in each group.The control group received epidural anesthesia under ultrasound,and the observation group received the combined lumbar-epidural anesthesia under ultrasound.The lidocaine dosage,anesthetic block time,anesthesia onset time and dosage of additional analgesic,as well as the changes in vital signs such as diastolic blood pressure(DBP),systolic blood pressure(SBP)and heart rate(HR),between the two groups of patients were compared.In addition,the thrombelastogram,anesthetic effects and occurrence of adverse reactions also were compared between two groups.Results:The lidocaine dosage,anesthetic block time,anesthesia onset time and dosage of additional analgesic of the observation group were significantly higher than those in the control group,and the differences were statistically significant(t=8.657,23.483,12.785,16.600,P<0.05),respectively.There were no statistically significant differences in DBP,SBP,HR,comprehensive coagulation index(CI),reaction time(R),formation time of blood cell agglutination(K)and incidence of adverse reactions between two groups before anesthesia,at the 30th minute after anesthesia and after the end of anesthesia(P>0.05).Compared with α angle before anesthesia and at the 30th minute after anesthesia,the α angles of the two groups increased significantly after anesthesia(t=6.564,5.783,P<0.05),respectively.The mechanical strength(G)of the blood clot and the maximum amplitude(MA)of chromatogram of the observation group were significantly reduced after completed anesthesia,and the differences of them were statistically significant(t=8.480,4.236,P<0.05),respectively.There were no significant differences between G and MA in the control group(P>0.05).The total effective rate of the observation group was 97.50%,which was significantly higher than 80.00% of the control group,and the difference was statistically significant(x2=4.507,P<0.05).Conclusion:The combined spinal-epidural anesthesia under the assistant of ultrasound location can effectively reduce the amount of anesthetics in patients with lower limb fracture,which has fast block and effect.In addition,it has little influence on circulatory function,and it is less likely to form a hypercoagulable state.It has better clinical anesthesia effect.
