目的 分析冠状动脉旁路移植术(CABG)后桡动脉(RA)桥通畅率的影响因素。 方法 回顾性分析在CABG术中使用RA桥,并于术后1年复查冠状动脉计算机断层扫描血管造影术(CTA)患者65例。收集患者术前、术中及术后的相关资料,采用多因素logistic回归分析筛选RA桥通畅率的影响因素。 结果 RA桥靶血管近端狭窄程度≥80%( OR=0.212, 95% CI: 0.049~0.912, P=0.037)和靶血管在左前降支区域( OR=0.104, 95% CI: 0.012~0.921, P=0.042)是RA桥术后通畅率的独立保护因素,而术后未规范联用抗痉挛药物( OR=6.825, 95% CI: 1.857~25.083, P=0.004)是RA桥通畅率的独立危险因素。 结论 CABG术中RA桥靶血管的合理选择和术后联用抗痉挛药物是RA桥通畅率的独立影响因素。 相似文献

Context Coronary artery bypass graft (CABG) surgery is associated with a decline in cognitive function, which has largely been attributed to the use of cardiopulmonary bypass (on-pump procedures). Cardiac stabilizers facilitate CABG surgery without use of cardiopulmonary bypass (off-pump procedures) and should reduce the cognitive decline associated with on-pump procedures. Objective To compare the effect of CABG surgery with (on-pump) and without (off-pump) cardiopulmonary bypass on cognitive outcome. Design and Setting Randomized controlled trial conducted in the Netherlands of CABG surgery patients enrolled from March 1998 through August 2000, with 3- and 12-month follow-up. Participants and Intervention Patients scheduled for their first CABG surgery (mean age, 61 years; n = 281) were randomly assigned to off-pump surgery (n = 142) or on-pump surgery (n = 139). Main Outcome Measures Cognitive outcome at 3 and 12 months, which was determined by psychologists (blinded for randomization) who administered 10 neuropsychological tests before and after surgery. Quality of life, stroke rate, and all-cause mortality at 3 and 12 months were secondary outcome measures. Results Cognitive outcome could be determined at 3 months in 248 patients. Cognitive decline occurred in 21% in the off-pump group and 29% in the on-pump group (relative risk [RR], 0.65; 95% confidence interval [CI], 0.36-1.16; P = .15). The overall standardized change score (ie, improvement of cognitive performance) was 0.19 in the off-pump vs 0.13 in the on-pump group ( P = .03). At 12 months, cognitive decline occurred in 30.8% in the off-pump group and 33.6% in the on-pump group (RR, 0.88; 95% CI, 0.52-1.49; P = .69). The overall standardized change score was 0.19 in the off-pump vs 0.12 in the on-pump group ( P = .09). No statistically significant differences were observed between the on-pump and off-pump groups in quality of life, stroke rate, or all-cause mortality at 3 and 12 months. Conclusion Patients who received their first CABG surgery without cardiopulmonary bypass had improved cognitive outcomes 3 months after the procedure, but the effects were limited and became negligible at 12 months. 相似文献

目的 探讨不停跳下冠状动脉旁路移植术(OPCABG)围术期输入红细胞对于术后近期桥血管通畅率的影响.方法 选择2013 年6月至2015 年6月在安徽医科大学第一附属医院行OPCABG的106例(共127例,失访21例)患者为研究对象,依据患者围术期红细胞的使用与否分为两组:组Ⅰ(输注红细胞组,71例);组Ⅱ(未输注红细胞组,35例).术后1年左右行冠脉CT检查,对比观察两组患者各桥血管通畅情况.结果 组Ⅱ桥血管通畅率(96.97%)高于组Ⅰ(90.40%),差异有统计学意义(P<0.05),组Ⅱ大隐静脉桥血管通畅率(96.92%)高于组Ⅰ(88.15%),差异有统计学意义(P<0.05),而两组间乳内动脉桥血管通畅率比较差异无统计学意义(P>0.05).结论 OPCABG围手术期输血会加大近期大隐静脉桥血管再狭窄的发生率. 相似文献

目的:对非体外循环冠状动脉旁路移植术(off-pump coronary artery bypass,OPCAB)中测定的血流资料和术后近中期结果进行分析,探讨两者间的相关性。 方法:回顾性收集2013年1月至2016年6月在北京大学人民医院行单纯OPCAB手术的患者资料,分析并对比患者术中测定的血流指标、术后早期临床事件及术后随访资料。术后早期临床事件包括围手术期心肌梗死、主动脉内球囊反搏(intra-aortic balloon pump,IABP)使用、再次手术、新发心房颤动及院内死亡。 结果:共463例患者纳入研究,平均年龄(62.80±8.36)岁,其中女性115例(24.8%),平均吻合桥血管(3.10±0.81)支,共1 435支桥血管,术中血流测定结果显示移植血管平均血流量(mean flow,MF)为(32.34±14.45) mL/min,搏动指数(pulsatility index,PI)为2.87±0.92。23例(5%)患者发生围手术期心肌梗死,IABP使用者11例,术后30 d死亡患者4例。围手术期心肌梗死组的桥血管MF低于无心肌梗死组,而PI高于无心肌梗死组( P<0.05)。其他术后早期临床事件组间比较,其MF、PI值差异均无统计学意义。Logistic回归分析显示移植血管低MF( Wald=5.684, P=0.017,95% CI:0.894~0.989)、高PI( Wald=9.040, P=0.003,95% CI:1.252~2.903)是围手术期心肌梗死的危险因素。随访最长时间37个月,共7例患者死亡,死亡组与生存组间术中血流指标差异均无统计学意义。与动脉桥正常血流组比较,低MF组(MF<10 mL/min)随访期间死亡率较高,差异有统计学意义( OR=9.6, P<0.05)。 结论:移植血管低MF、高PI会增加围手术期心肌梗死发生率,动脉桥MF<10 mL/min 会增加患者术后中期死亡率,但仍需进一步研究证实,术中血流测定技术对OPCAB术后近中期结果有一定的预测价值。 相似文献

Context Inflammation and ischemia-reperfusion injury during coronary artery bypass graft (CABG) surgery requiring cardiopulmonary bypass are associated with postoperative myocardial infarction (MI) and mortality. Objective To determine the efficacy and safety of pexelizumab, a C5 complement inhibitor, in reducing perioperative MI and mortality in CABG surgery. Design, Setting, and Participants A randomized, double-blind, placebo-controlled trial, including 3099 patients (=" BORDER="0"> 18 years) undergoing CABG surgery with or without valve surgery at 205 hospitals in North America and Western Europe from January 2002 to February 2003. Interventions Patients were randomly assigned to receive intravenous pexelizumab (2.0 mg/kg bolus plus 0.05 mg/kg per hour for 24 hours; n = 1553) or placebo (n = 1546) 10 minutes before undergoing the procedure. Main Outcome Measures The primary composite end point was the incidence of death or MI within 30 days of randomization in those undergoing CABG surgery only (n = 2746). Secondary analyses included the intent-to-treat analyses of death or MI composite at days 4 and 30 in all 3099 study patients. Results After 30 days, 134 (9.8%) of 1373 of patients receiving pexelizumab vs 161 (11.8%) of 1359 of patients receiving placebo (relative risk, 0.82; 95% confidence interval, 0.66-1.02; P = .07) died or experienced MI in the CABG surgery only population. In the intent-to-treat analyses, 178 (11.5%) of 1547 patients receiving pexelizumab vs 215 (14.0%) of 1535 receiving placebo died or experienced MI (relative risk, 0.82; 95% confidence interval, 0.68-0.99; P = .03). The trial was not powered to detect a reduction in mortality alone. Conclusions Compared with placebo, pexelizumab was not associated with a significant reduction in the risk of the composite end point of death or MI in 2746 patients who had undergone CABG surgery only but was associated with a statistically significant risk reduction 30 days after the procedure among all 3099 patients undergoing CABG with or without valve surgery. 相似文献

Background Bacterial infections remain a serious complication following coronary artery bypass grafting (CABG). The objective of the study was to determine the effectiveness of a guideline for the appropriate use of antibiotics in CABG during the perioperative period.
Methods Six hundred and fourteen hospitalized patients who had undergone CABG from January to June 2006 were randomly allocated to an intervention group and a control group. The data on the hospital stay, days of antibiotic used, types of prophylactic antibiotics used, surgical wound infection and pulmonary infection and antibiotic costs for the patients were compared.
Results The postoperative hospitalization days of the intervention group were significantly fewer than that for the control group (P <0.05). The time of antibiotic use and post-infection treatment time were also significantly less in the intervention group than in the control group (P <0.05). The average hospital daily cost and total cost of antibiotics were less in the intervention group than in the control group (P <0.05). Compared with the control group, prophylactic antibiotic use in the intervention group was more reasonable.
Conclusions The guideline for the appropriate use of antibiotics in CABG during the perioperative period is effective strategies for reducing antibiotic costs, the time of antibiotic use and post-infection treatment time without compromising the patients’ clinical outcome. 相似文献

目的:探讨冠心病患者行体外循环冠状动脉旁路移植术(EC-CABG)和非体外循环冠状动脉旁路移植术(NEC-CABG)心功能恢复的效果。方法:回顾性分析2000年1月至2001年12月连续120例冠状动脉旁路移植术,其中EC-CABG组69例,手术在体外循环下进行;NEC-CABG组51例,不用体外循环,心脏跳动下完成旁路移植手术。应用肺动脉漂浮导管连续监测心排血量(CO)、心排血指数(CI)、左心室每搏功指数(LVSWI),记录围术期主动脉内球囊反搏(IABP)使用情况、机械通气时间、正性肌力药物用量、血液超滤的使用情况、手术时间、输血量等。结果:NEC-CABG组CO、CI、LVSWI较EC-CABG组恢复快;NEC-CABG组使用IABP(1.9%)较EC-CABG组(8.6%)明显降低(P<0.05);NEC-CABG组机械通气时间较EC-CABG组短,正性肌力药物使用量明显减少,且EC-CABG组多需要进行血液超滤。结论:非体外循环冠状动脉旁路移植术显示了良好的心功能恢复效果,加快了患者的康复。 相似文献
