本文报道我院所做肾移植的患者中有6例发生了脑部并发症,结果4例死亡,1例切除移植肾后转入腹膜透析。认为肾移植术后发生脑部并发症的机理虽不太清楚,但从本组病例分析,可能与环孢素A的毒性作用、急性排斥反应、感染和糖尿病有关。 相似文献

OBJECTIVE: To assess the effect of the waiting period before elective open-heart surgery on patient outcomes. DESIGN: Retrospective analysis. SETTING: The Montreal Heart Institute, a referral centre in cardiology and cardiac surgery. PATIENTS: All 568 patients who underwent open-heart surgery on an elective basis or following urgent admission or interhospital transfer between October 1991 and February 1992. MAIN OUTCOME MEASURES: In-hospital death rate, incidence of postoperative complications, length of stay in the intensive care unit (ICU) and total length of hospital stay. RESULTS: A total of 206 patients (151 men and 55 women with an average age of 59.0 [standard error of the mean (SEM) 1] years) underwent elective surgery, and 362 patients (264 men and 98 women with an average age of 62.0 [SEM 1] years) underwent urgent surgery. The mean wait for elective surgery was 2.8 (SEM 0.2) months. There was no significant difference between the two groups in the in-hospital death rate (4% v. 4%), the average length of stay in the ICU (4.4 [SEM 0.2] days v. 5.8 [SEM 1] days) or the average total length of hospital stay (9.0 [SEM 0.4] days v. 9.1 [SEM 1] days). As would be expected, postoperative complications developed in significantly more patients in the urgent group (27%) than the elective group (18%) (p = 0.02). Eight patients were admitted on an urgent basis for surgery owing to worsening symptoms or acute myocardial infarction after a mean wait of 4.6 months. One patient died suddenly at home 1 month after medical investigation while awaiting repeat coronary artery bypass grafting. Among the 206 patients who underwent elective surgery there was no relation between waiting time and adverse clinical outcomes after surgery. CONCLUSIONS: The results suggest that the wait before elective open-heart surgery had no effect on patient outcome after surgery in our institution. A policy of a short waiting period before elective open-heart surgery for patients whose condition is stable is safe and acceptable only if rapid access to medical and surgical treatment is available should it become necessary. 相似文献

目的比较异氟醚和丙泊酚预处理在小儿体外循环心脏直视手术中对脑的保护作用。方法将40例年龄不超过4岁的先天性心脏病患儿随机分为异氟醚组(n=20)和丙泊酚组(n=20),在手术前(T1)、体外循环开始后5min(T2)、阻断主动脉时(T3)、体外循环后30min(T4)、体外循环术毕(T5)、停止体外循环后6h(T6)、停止体外循环后24h(T7)7个时间点采集血样,采用酶联免疫吸附测定(ELISA)法检测血清中S-100β蛋白的表达,头颅CT检测术前、术后患儿的脑部情况。结果两组患儿术前S-100β蛋白的差异无统计学意义(P>0.05),两组S-100β蛋白的表达在体外循环开始后均上升,术后下降至术前水平(P>0.05)。异氟醚组患儿T4和T5时间点的S-100β蛋白表达水平比T1时间点显著升高(P<0.05),丙泊酚组患儿T4、T5和T6时间点的S-100β蛋白表达水平比T1时间点显著升高(P<0.05)。在T4、T5、T6及T7时间点,丙泊酚组患儿S-100β蛋白的表达水平显著高于异氟醚组(P<0.05)。丙泊酚组患儿术后并发症的发生率高于异氟醚组(P<0.05),而两组患儿脑水肿的检出率差异无统计学意义(P>0.05)。结论异氟醚预处理在体外循环小儿心脏直视手术中的脑保护效果方面优于丙泊酚预处理。 相似文献

Between March 1975 and March 1980, 50 patients aged 70 to 78 years underwent open-heart surgery at the Montreal Heart Institute. Coronary bypass was performed in 23 patients, valve replacement in 16 and combined coronary and valve surgery in 11. There were four early deaths, all due to cardiac causes. Early postoperative complications occurred in 58% of the patients. There were seven late deaths, five in the valve replacement groups and two in the isolated coronary bypass group. The cumulative survival rate 5 years after surgery was estimated at 76%. While 82% of the survivors were in functional class III or IV before surgery, 90% were in class I or II when last seen, after an average postoperative follow-up of 3 years. Nonfatal late complications occurred in eight of the survivors, one of whom suffered a major hemorrhage due to anticoagulant therapy. Thus, open-heart operations can be offered to the elderly, with a low risk of operative death. The late clinical improvement, with a return to a normal lifestyle, justifies a surgical approach for patients in otherwise good general condition. 相似文献

目的:探讨先天性心脏病婴儿进行心内直视手术时,应用中低温低流量体外循环的安全性和可行性。方法:40例因先天性心脏病行心内直视手术患儿,随机分为观察组(n=20):应用中度低温低流量的灌注技术;对照组(n=20):应用浅低温高流量的灌注技术。记录转机时间、手术时间、降温时间、复温时间、不良反应的发生,对两组术中血气、术后脑功能进行对比。结果:中低温低流量灌注时静脉血氧饱和度均在80%以上,无缺氧酸中毒的血气表现,血乳酸值也未升高,观察组与对照组各时间点的动一颈内静脉血的乳酸浓度差无明显变化(P〉O.05),术后恢复良好,术后无明显体外循环相关并发症。结论:对婴儿进行心内的直视手术时,采用中低温低流量体外循环,能够满足脑组织的氧供,而且减少血液的破坏,保持术野的清晰,有利于减少长时间高流量灌注的不良反应,为临床开展婴儿复杂型先心手术的脑保护提供新手段。 相似文献

Extracorporeal circulation during open-heart surgery may damage cellular and humoral factors in the blood. Phagocytic functions of circulating polymorphonuclear leukocytes were investigated in 10 patients 1 day before, then 1 hour, 2, 4 and 10 days after open-heart surgery. Transient diminutions in the phagocytic capacity of polymorphs was found for Staphylococcus aureus and Escherichia coli in one patient, and E. coli only in two patients up to the 4th postsurgical day. A positive correlation was found between the duration of extracorporeal circulation and the transient diminutions in phagocytic capacity for these three patients. However, the bactericidal capacity of polymorphs and their capacity to reduce nitroblue tetrazolium were normal in all patients. The serum concentrations of total hemolytic complement, C3, IgG and IgM were generally diminished up to the 4th day after surgery, but the opsonic power of the serum was almost normal in all the patients. 相似文献

In the investigation of several blood stream infections following open-heart surgery, sutures and other material that had been exposed and handled in the sterile field were examined bacteriologically. One hundred and seventy-five open-heart operations were carried out during the study period and a high percentage of the specimens cultured yielded viable staphylococci and diphtheroids. Glove powder, textile fibres, and skin squames were found in the dust that collected in the room during the operations and staphylococci were frequently recovered from this source, and from the floor. Although the air supply to the theatre appeared to be of good quality, it is suggested that air currents within the room had caused dissemination of this foreign material and had probably contributed to wound infections. 相似文献
