THE STUDY ON THE CHANGES OF ZINC, COPPER, CALCIUM AND MAGNESIUM IN PLASMA AND ERYTHROCYTES DURING CARDIOPULMONARY BYPASS

Objective To study the changes and their influence factors involved of zinc, copper, calcium and magnesium in plasma and erythrocytes during cardiopulmonary hypass(CPB). Methods Zinc, copper, calcium and magnesium values in plasma and erythrocytes were measured by atomic absorption spectrophotometer during CPB. Results Zinc and copper levels in plasma were significantly elevated above preinduction level before perfusion, hut calcium and magnesium levels did not change significantly; zinc, copper and calcium levels in plasma were significantly below preoperation level during CPB, hut magnesium level in plasma was significantly increased above preoperation; zinc level in plasma was increased to preoperation level after CPB and began to decrease again at 8 hours after CPB,copper level in plasma was increased to preoperation level at 20 hours after CPB, calcium in plasma was increased significantly from beginning to 8 hours after CPB, magnesium level in plasma was decreased to preoperation level at 8 hours afterCPB. Concentration of zinc , copper, calcium and magnesium in erythrocytes did not change significantly. Conclusion During CPB, the changes of zinc, copper, calcium and magnesium had relation to hemodilution, operative wound, carrier protein, stress and component of priming Solution and cardioplegic solution, hut no relation to transferfrom plasma erythrocytes. The results indicate that it is beneficial to patient‘s recovery to supplement zinc, copper, calcium and magnesium properly by different ways during cardiac perioperation.     

室间隔缺损并肺动脉高压102例外科治疗

先天性心脏病室间隔缺损（ＶＳＤ）是一常见多发病，由于存在左向右分流，常导致肺动脉高压（ＰＨ），使围手术期死亡率增加，预后不佳，故早期发现、早期手术治疗己被重视。本文对１０２例ＶＳＤ·ＰＨ患者外科手术治疗进行分析，并对手术适应症、手术径路、并发症预防及术后处理进行讨论。     

体外循环期间钙动态变化的研究

观察32例患者体外循环期间血浆及红细胞内钙的动态变化。目的在于揭示其变化规律，为更好的保护心肌提供新的措施和理论依据。结果：麻醉后体外循环前血浆钙较术前显著升高，体外循环开始显著下降；40min恢复至术前水平；停机时显著升高至停机8h。术前、中、后红细胞内钙无显著变化。体外循环期间钙变化与血液稀释、应激反应、预充液及心脏停跳液中含钙离子有关。高钙可导致心肌缺血及再灌注时大量钙进入心肌细胞，引起心肌细胞损伤。所以，体外循环期间，特别是复灌期适当降低钙浓度，对术中、后心肌功能恢复具有重要作用。

双腔右心室的外科治疗

报道15例右室异常肌束增殖致双腔右心室(DCRV),是少见的先天性心脏畸形,影响右心排血功能。诊断依据为:右室近腔高压、远腔低压,形成压力阶差,可为裂隙性或隔膜性狭窄,依靠超声与右心导管或造影确诊。须与流出道狭窄、TOF、肺动脉瓣狭窄鉴别。术中应探明三尖瓣和流出道,采用右房切口修复VSD在近腔者、右室切口切除狭窄与修复VSD在远腔者,术野暴露清楚。狭窄口切除,成人>18mm、儿童>16mm为宜。

室间隔缺损并肺动脉高压患者临床指标与肺超微结构的比较

目的　探讨室间隔缺损合并肺动脉高压临床资料与肺超微结构的关系。方法　分别应用心导管术观察室缺患者右心及肺循环血流动力学指标 ;应用透射电镜观察肺超微结构的变化 ,且二者进行对比。结果　肺血流动力学指标与肺超微结构变化之间无明显统计学关系。结论　室间隔缺损合并肺动脉高压的成因除牵张刺激及剪切应力外 ,肺血管本身发育异常可能是主要原因
