摘要:: 目的观察地塞米松对室间隔缺损（VSD）患者介入治疗后cTnI和CRP的影响。方法选取VSD患者42例，随机分为激素组（术后连续3 d静脉注射地塞米松0.3 mg/kg）和对照组（未给予地塞米松）。于术前、术后即刻、4、24和72 h采血，用ELISA法检测血清cTnI含量及变化，用免疫比浊法检测血清CRP含量及变化。结果 ①血清cTnI水平术后即刻、4及24 h明显升高，两组在术后即刻、4 h无显著性差异，24 h激素组显著低于对照组（P<0.05）；72 h激素组降至术前水平，而对照组仍高于术前，两组间差异显著（P<0.05）。②血清CRP水平术后24 h较前明显升高，激素组显著低于对照组（P<0.05）；激素组72 h降至术前水平，而对照组仍高于术前，两组间差异显著（P<0.05）。结论室间隔缺损患者介入治疗术后，地塞米松的使用可减轻心肌损伤，抑制炎症反应。

Abstract:: AIM To observe the effects of dexamethasone on cardiac troponin I (cTnI) and C reactive protein (CRP) after interventional closure of ventricular septal defects. METHODS Fortytwo ventricular septal defects（VSD） were randomly assigned to dexamethasone group ［(0.3 mg/(Kg·d)］ i.v three days in serial) and control group (no dexamethasone given). All the patients were taken serial blood samples before, immediately after, as well as 4, 24 and 72 h after intervention. The cTnI levels were measured by ELISA and the levels of CRP were detected by immunonephelometric assay. RESULTS ①Serum cTnI levels increased significantly at the end of the operation, as well as 4 h and 24h after the operation. Significant differences were not found between the two groups at the end and 4h after intervention（P>0.05）. However, the elevations at 24 h were more prominent in the control group than those in the dexamethasone group（P<0.05）.②Serum CRP levels increased significantly at 24 h after the operation. The CRP in the control group was higher compared with that in the dexamethasone group（P<0.05）. At 72 h, the cTnI and CRP levels in the dexamethasone group lowered down to the levels before operation while the levels in the control group lowered to the levels higher than those before operation. CONCLUSION After interventional closure of ventricular septal defects, the use of hormone may decrease the myocardial damage and inhibit inflammatory reaction.
