Percutaneous Silastic catheters (PSCs) are used in premature infants to deliver total parenteral nutrition. We report two cases in which migration of the catheter into the right atrium resulted in rapid onset of shocklike symptoms. Pericardial effusion and tamponade were diagnosed by echocardiography. Subxiphoid pericardiocenteses were performed, with immediate clinical improvement. In both cases, fluid withdrawn from the pericardial space was analyzed to be hyperalimentation and intravenous fat emulsion. Pericardial effusion and tamponade should be suspected in any infant with a PSC line in place who develops sudden onset of shocklike symptoms.
经皮硅橡胶导管（PSCs）用于早产儿进行全胃肠外营养。我们报告了两例导管迁移至右心房导致休克样症状迅速出现的病例。通过超声心动图诊断为心包积液和心包填塞。进行了剑突下心包穿刺术，临床症状立即改善。在这两例病例中，从心包腔抽出的液体经分析为高营养物质和静脉脂肪乳剂。对于任何置有PSCs导管且突然出现休克样症状的婴儿，都应怀疑有心包积液和心包填塞。
