Abstract:
Objective:To investigate the effect of nerve block anesthesia on hemodynamics in elderly patients undergoing unilateral lower limb trauma surgery.Methods:From February 2017 to June 2019, 100 elderly patients with unilateral lower extremity trauma admitted in our hospital were selected in this study.According to different anesthesia methods, the patients were divided into two groups, with 50 cases in each group.Group B was given light specific gravity subarachnoid anesthesia, while group A received nerve block anesthesia.The anesthesia effect, hemodynamic parameter changes, complications and incidence of adverse reactions between the two groups were compared.Results:The total effective rate of group A was 98.00%(49/50), which was significantly higher than that of group B[86.00%(31/50)], the difference between the two groups was statistically significant(χ 2=16.973, P<0.05). Before anesthesia, there were no statistically significant differences in diastolic blood pressure, heart rate and blood oxygen saturation between the two groups(all P>0.05). At 15 minutes after anesthesia, the diastolic blood pressure, heart rate and blood oxygen saturation in group A were (70.32±3.42)mmHg, (86.28±2.42)times/min, (139.03±2.63)%, respectively, which in group B were (70.26±1.66)mmHg, (86.73±1.63)times/min, (140.97±1.84)%, respectively.At 30 minutes after anesthesia, the diastolic blood pressure, heart rate and blood oxygen saturation in group A were (68.73±2.11)mmHg, (85.26±0.52)times/min, (136.18±3.89)%, respectively, which in group B were (70.98±1.92)mmHg, (87.24±2.31)times/min, (140.39±0.77)%, respectively.At 60 minutes after anesthesia, the diastolic blood pressure, heart rate, blood oxygen saturation in group A were (67.34±3.25)mmHg, (86.26±1.31)times/min, (134.89±2.37)%, respectively, which in group B were (71.01±3.12)mmHg, (87.39±1.32)times/min, (140.99±1.64)%, respectively.The differences between the two groups were statistically significant( t=11.315, 10.924, 10.599, t=13.411, 8.226, 9.779, t=9.057, 8.497, 10.131, all P<0.05). The incidence of complications and adverse reactions in group A was 2.00%(2/50), which was significantly lower than that in group B[18.00%(9/50)], the difference between the two groups was statistically significant(χ 2=16.913, P<0.05). Conclusion:Nerve block anesthesia is effective in elderly patients with unilateral lower limb trauma surgery, which can effectively stabilize the hemodynamics and reduce the incidence of complications and adverse reactions.
