The Application Effect of Ultrasound-guided Femoral and Sciatic Nerve Block in Anesthesia for Calcaneal Fracture Surgery
Objective:To explore the application effect of ultrasound-guided femoral and sciatic nerve block in anesthesia for calcaneal fracture surgery.Method:Eighty patients with calcaneal fractures admitted to Heze Medical College Affiliated Hospital from February 2020 to February 2023 were selected and randomly divided into the control group(spinal anesthesia)and the observation group(ultrasound-guided femoral and sciatic nerve block)using a random number table method.The anesthesia effects of the two groups were compared;the heart rate(HR),mean arterial pressure(MAP)and blood oxygen saturation(SpO2)of two groups before anesthesia(T0),5 minutes after anesthesia(T1),10 minutes after anesthesia(T2),15 minutes after anesthesia(T3)and 30 minutes after anesthesia(T4)were compared;stress response indicators[adrenaline(E),cortisol(Cor)],coagulation function[thrombin time(TT),prothrombin time(PT),activated partial thromboplastin time(APTT)]and incidence of adverse reactions in the two groups were compared.Result:The rate of grade Ⅰ anesthesia effect in the observation group was higher than that in the control group,the difference was statistically significant(P<0.05).There were no statistically significant differences in the levels of HR,MAP and SpO2 between the two groups at T0 and T1(P>0.05);the HR and MAP at time T2,T3,and T4 in the control group were higher than those at time T0,and SpO2 was lower than that at time T0,with statistically significant differences(P<0.05);there were no statistically significant differences in HR,MAP,and SpO2 at time T2,T3,and T4 in the observation group compared to time T0(P>0.05);at time T2,T3,and T4 in the observation group,HR and MAP were lower than those in the control group,and SpO2 were higher than those in the control group,with statistical significance(P<0.05).Before surgery,there were no statistically significant differences in E and Cor levels between the two groups(P>0.05);after 1 hour of surgery,the levels of E and Cor in both groups increased,but those in the observation group were lower than those in the control group,the differences were statistically significant(P<0.05).Before surgery,there were no statistically significant differences in the levels of TT,PT and APTT between the two groups(P>0.05);after 1 hour of surgery,the levels of TT,PT and APTT in both groups increased,and those in the observation group were higher than those in the control group,with statistical significance(P<0.05).The incidence of adverse reactions in the observation group was lower than that in the control group,the difference was statistically significant(P<0.05).Conclusion:Ultrasound guided femoral and sciatic nerve block is effective in anesthesia for patients with calcaneal fractures,reducing stress reactions,stabilizing intraoperative hemodynamics,improving blood hypercoagulability,and reducing the incidence of complications.
