摘要
为探讨体外循环(CPB)心脏手术病人降钙素基因相关肽(CGRP)的变化和临床意义,对15例先天性心脏病和11例风湿性心脏病(男19例,女7例;年龄6~56岁;体重13~68kg)行CPB心脏手术的病人,采血用放免法测定CGRP含量。结果麻醉后转流前、阻断主动脉20、40分钟、开放主动脉即刻、开放后20、40分钟、术后6小时和术后10天共8个时点CGRP含量分别为2.392±1.375、7.482±6.793、4.666±2.712、6.540±4.500、7.826±7.269、9.289±4.976、5.242±4.014、3.983±2.887pmol/L。与转流前比较,CGRP含量在阻断主动脉至开放主动脉明显升高,开放主动脉40分钟达高峰(P<0.001),术后6小时稍有回落,但仍高于转流前(P<0.005),术后10天虽显著回落,但仍显著高于转流前水平(P<0.05)。
Aim:The purpose of current study was to evaluate the changes of calcitonin gene related peptide(CGRP) and their clinical significance on patients undergoing open heart surgery under cardiopulmonary bypass(CPB).Clinical material and method:The content of CGRP was studied in 26 patients(15 with congenital heart disease and 11 with rheumatic valve disease)using radioimmunoassay method.There were 19 males and 7 females with a mean age of 23.4±18.25 years(range,6 to 56 years).Blood samples were taken at eight different time intervals.Result:The content of CGRP was increased significantly during CPB when compared to its basic level before CPB(P<0.001).The content of CGRP reached its highest level at 40 minute after releasing aortic cross clamping.On 10 postoperative day the CGRP decreased significantly but is was still higher than basic level.Cononclusion:The elevation of CGRP may play an important role in myocardial protection during CPB.
