目的探讨不同麻醉方式对老年合并心血管疾病白内障手术患者心率变异性(HRV)的影响。方法选择老年心血管疾病白内障择期手术病例60例(60只眼);全部病例均在局麻下行白内障摘除联合人工晶状体植入手术;根据手术麻醉方式不同,将60例患者分为表面麻醉组(Ⅰ组)和球周麻醉组(Ⅱ组),每组30例;以24 h动态心电图(DCG)进行HRV频域检测,分别比较Ⅰ组与Ⅱ组间以及两组手术前2 h、术中、术后2 h三个不同时段的低频功率(LF)、高频功率(HF)及LF/HF各项指标的变化情况。结果Ⅱ组LF、HF、LF/HF的各项指标均显著低于与Ⅰ组(P<0.05);Ⅰ组除LF外,HF、LF/HF在术中较术前2 h显著下降(P<0.05);Ⅱ组LF、HF、LF/HF在术中和术后2 h均较术前2 h显著下降(P<0.05或P<0.01)。结论 HRV能较为敏感地反映不同麻醉方式对自主神经系统(ANS)功能的影响;在表面麻醉方式下进行白内障手术,可能对心脏ANS功能损害较小,提示用表面麻醉进行白内障手术可能更具有安全性和稳定性。老年心血管病白内障手术,无论是表面麻醉还是球周麻醉,术中和术后均可能是诱发心血管事件的关键时期。 相似文献

目的 观察术前持续性ST-T改变的老年患者,在上腹部手术围术期发生急性心肌缺血的比率.方法 选择拟行上腹部择期手术者58例,按心电图是否存在持续性ST-T改变分为观察组30例(A组),对照组(B组)28例.于手术后给予24h或48h动态心电图(DCG)检查,分析ST-T(U)变化及继发的心律失常.同时观察胸痛、呼吸困难等表现,了解心肌酶谱、肌钙蛋白等实验室检查结果.结果 58例中,50例完成24h、8例完成48h DCG检查.A组8例(26.67%)发生19阵次缺血性ST-T(U)变化,同时有4例发生6阵次的继发于ST-T变化的心律失常,而B组共发生1例(3.57%)2阵次的缺血性ST-T改变和继发的2阵次心律失常,两组比较有显著性差异(P<0.05).结论 术前有ST-T持续性改变的老年患者,上腹部手术后早期发生心肌缺血及继发的严重心律失常比率较高,可能是诱发围术期心跳骤停的主要原因之一. 相似文献

OBJECTIVE--To study the incidence, predisposing factors, and clinical significance of arrhythmias early and late after the Fontan operation for congenital heart disease. PATIENTS AND METHODS--All 104 consecutive patients undergoing Fontan repair from 1975 to 1988 were studied retrospectively. Hospital records were reviewed for perioperative arrhythmia. Clinical information and annual electrocardiograms were available for all 78 hospital survivors during a follow up of up to 13 years (mean 3.7 years). Ambulatory electrocardiographic monitoring was performed in 67 patients (81%). RESULTS--Eleven patients (10.6%) developed a perioperative tachycardia (eight, atrial flutter; three, His bundle tachycardia). Multivariate analysis showed that raised preoperative mean pulmonary artery pressure and low aortic saturation were significant risk factors for the development of atrial flutter (r2 = 0.32, p = 0.0001) but not for His bundle tachycardia. Despite intensive medical treatment 10 of these 11 patients died. At the last visit 72 (92%) of the 78 patients were in sinus rhythm on their standard 12 lead electrocardiogram. Junctional rhythm was present in three patients, two patients had atrial flutter, and one had a paced rhythm. Ambulatory monitoring did not show important bradycardia or ventricular arrhythmias. Actuarial survival free of supraventricular arrhythmia was 82% at eight years after operation. Multivariate analysis identified older age, increased right atrial size, and raised mean preoperative pulmonary artery pressure as risk factors for arrhythmia during intermediate follow-up (r2 = 0.46, p less than 0.001). Late tachycardias, in contrast to those occurring in the perioperative period, were not associated with an increased mortality. CONCLUSIONS--Except for his bundle tachycardia in the perioperative period, early and late arrhythmias after a Fontan operation seem to be a consequence of adverse preoperative and postoperative haemodynamic function. The perioperative outcome is therefore poor even when the patient can be restored to sinus rhythm. Medical and surgical modifications to improve the haemodynamic disturbances associated with arrhythmias are therefore indicated. 相似文献

目的探讨围术期临床心脏疾病中危因素患者心血管事件(PCE)中心律失常和心肌缺血的发生及其与心率变异性(HRV)的关系。方法随机选择非心脏择期手术围术期临床心脏疾病中危因素患者171例,根据年龄将其分为3组:①组,〈65岁共54例;②组,65-75岁共72例;③组,〉75岁共45例。所有患者行术前与术后连续48h动态心电图(DCG)监测,对Ⅱ级以上室性期前收缩、阵发性室上性心动过速(PSVT)、阵发性心房颤动(PM)及传导阻滞等心律失常,阵发性sT段缺血性改变等作出分析、诊断;删除影响HRV及sT段分析的病例,选择113例患者的DCG分析研究HRV的变化及其与心律失常、心肌缺血发生的关系。结果心律失常及心肌缺血发生情况:术前各组相比差异无统计学意义(P〉0.05);术后①组ⅣA级室性期前收缩、PAf及心肌缺血的发生增多(P〈0.05);②组与③组中,除③组Ⅱ级室性期前收缩无明显增加外,其余术后均明显增多,差异有统计学意义(P〈O.05)。术后组间比较:随年龄增大,心律失常及心肌缺血发生增加且类别增多。术前发生心肌缺血15例(13.27%),术后发生40例(35.40%)。术后发生PAf23例(13.45%),组间比较,随年龄增大PAf的发生增加(P〈0.05),其发生与左房增大无明显关系。HRV比较:术前组间比较,随年龄增大HRV呈下降趋势(P〈0.05),术后HRV各参数较术前显著降低(P〈0.05),术后第2个24h较第1个24hHRV指标进一步降低(除外②组的TI)(P〈O.05);术后组间比较,随年龄增长HRV均有不同程度的减低,③组高龄患者降低尤为显著(P〈O.05)。结论术后随患者年龄增大,复杂性及恶性心律失常、心肌缺血等PCE的发生增加,其自主神经功能降低更明显,HRV指标尤其是SDAA、TI等指标显著降低,迷走及交感神经张力的失衡相对更为严重且持续时间长。提示心律失常及心肌缺血的发生可能与自主神经系统活性HRV降低有关。 相似文献

目的观察非超声乳化老年白内障手术的心率变异性(HRV)改变,了解围手术期心脏自主神经系统(AbIS)功能的影响,为评估手术风险性研究提供理论依据。方法采用前瞻性研究方法,随机选择60例(60只眼)年龄〉/60岁无心血管病史的白内障摘除术患者,统一在局部麻醉下进行非超声乳化白内障囊外摘除+人工晶体植入手术。在手术前1d17:00开始至次日术后17:00,进行24h动态心电图(DCG)记录测定HRV频域指标。观察老年白内障患者手术前00:00~05:00时段(术前)、手术时段(术中)及术后12:00~17:00时段(术后)频域指标(LF、HF、LF/HF)的变化;分析其改变特点和原因。结果全部患者在围手术期间,三个时点HRV频域比较差异有统计学意义(P〈0.01);术中和术后HRV频域指标均明显低于术前(P〈0.05或〈0.01),术中HRV频域指标又明显低于术后(P〈0.05或P〈0.01)。结果表明在局部麻醉下进行非超声乳化白内障囊外摘除联合人工晶状体植入,术中和术后时点的HRV频域指标比术前明显降低,以术中时点的下降更为显著。结论局部麻醉或白内障手术创伤等应激刺激,对老年白内障患者ANS功能影响较为明显,提示术中和术后均可能是发生心血管事件的易发时期,应采取相应预防措施降低手术风险。 相似文献

Preoperative, perioperative and postoperative arrhythmias in 52 consecutive patients who underwent operation for Ebstein's anomaly were reviewed. There were 25 male and 27 female patients (mean age 18 years, range 11 months to 64 years). Thirty-four patients had one or more documented arrhythmias preoperatively (18 had paroxysmal supraventricular tachycardia, 10 had paroxysmal atrial fibrillation or flutter, 13 had ventricular arrhythmia and 3 had high grade atrioventricular block). Seven patients without documented arrhythmias had a history typical of tachyarrhythmias. During the perioperative and early postoperative periods, 14 patients had atrial tachyarrhythmias and 8 had ventricular tachycardia or ventricular fibrillation. There were seven deaths between day 1 and 27 months after operation. Five of these deaths were sudden (all in male patients, aged 12 to 34 years), and four of the patients had had perioperative ventricular tachycardia or ventricular fibrillation. One patient was taking one antiarrhythmic agent and another patient was taking two at the time of sudden death. Of the 18 patients with paroxysmal supraventricular tachycardia and 9 patients with paroxysmal atrial fibrillation or flutter preoperatively who were followed up for a mean of 40 and 36 months, respectively, 22 and 33% continued to have symptomatic tachycardia. Of the 11 patients (mean age 9 years) without preoperative documentation or symptoms of arrhythmia, follow-up data were obtained (range 1 to 144 months, mean 31) in 9 patients. None died suddenly or developed symptomatic arrhythmia. 相似文献
