摘　　要：目的探究不同浓度罗哌卡因在高龄高危患者骨科下肢手术麻醉中的效果。方法100例高龄高危骨科下肢手术患者,随机分为观察组和对照组,每组50例。观察组患者以0.75%罗哌卡因进行麻醉,对照组患者以0.60%罗哌卡因进行麻醉。对比两组患者麻醉效果及血氧饱和度(SpO_(2))、舒张压(DBP)、收缩压(SBP)及心率(HR)。结果观察组患者感觉起效时间(14.74±3.28)min、感觉阻滞时间(8.09±2.27)min、运动阻滞时间(2.50±1.78)min均短于对照组的(21.46±4.06)、(13.56±2.72)、(7.27±2.09)min,平面上界(5.8±2.5)T及运动神经阻滞程度(Bromage)分级(2.1±0.3)级低于对照组的(10.0±2.8)T、(2.7±0.4)级,差异有统计学意义(P<0.05)。观察组患者SpO_(2)(99.45±1.97)%、DBP(75.58±9.46)mm Hg(1 mm Hg=0.133 kPa)、SBP(135.70±12.90)mm Hg及HR(88.20±13.40)次/min均优于对照组的(75.94±1.89)%、(63.28±8.59)mm Hg、(103.30±11.80)mm Hg、(74.30±12.50)次/min,差异有统计学意义(P<0.05)。结论在高龄高危患者骨科下肢手术的麻醉中使用0.75%罗哌卡因可发挥显著麻醉效果,患者的生命体征更稳定,值得更进一步推广。Objective To investigate the effect of different concentrations of ropivacaine on anesthesia for lower extremity orthopaedic surgery in elderly and high-risk patients.Methods A total of 100 elderly and high-risk patients with lower extremity orthopaedic surgery were randomly divided into an observation group and a control group,with 50 cases in each group.The observation group was anesthetized with 0.75%ropivacaine,and the control group was anesthetized with 0.60%ropivacaine.The anesthesia effect,blood oxygen saturation(SpO_(2)),diastolic blood pressure(DBP),systolic blood pressure(SBP)and heart rate(HR)were compared between the two groups.Results The sensory onset time(14.74±3.28)min,sensory block time(8.09±2.27)min and motor block time(2.50±1.78)min of the observation group were shorter than(21.46±4.06),(13.56±2.72)and(7.27±2.09)min of the control group;the upper bound of the plane(5.8±2.5)T and the motor nerve conduction block(Bromage)grading(2.1±0.3)grades of the observation group were lower than(10.0±2.8)T and(2.7±0.4)grades of the control group;the differences were all statistically significant(P<0.05).In the observation group,the SpO_(2) was(99.45±1.97)%,the DBP was(75.58±9.46)mm Hg(1 mm Hg=0.133 kPa),the SBP was(135.70±12.90)mm Hg and the HR was(88.20±13.40)times/min,which were better than(75.94±1.89)%,(63.28±8.59)mm Hg,(103.30±11.80)mm Hg and(74.30±12.50)times/min in the control group,and the differences were all statistically significant(P<0.05).Conclusion The use of 0.75%ropivacaine in the anesthesia of lower extremity orthopaedic surgery in elderly and high-risk patients can exert a significant anesthetic effect,and the patient's vital signs are more stable,which is worthy of further promotion.
