Pericardial effusion and cardiac tamponade are rare but life-threatening complications of percutaneosuly inserted central line (PICL) use in extremely low birth weight (ELBW) neonates, with an incidence reported between 0.07% and 2% of PICLs placement. Timely diagnosis and pericardiocentesis has been proven to be life-saving.
The patient was a 620 g birth weight neonate who presented with sudden cardiac instability 18 days after the insertion of a PICL and in spite of a presumed satisfactory position of the catheter tip. The transthoracic echocardiography demonstrated severe pericardial effusion with evidence of cardiac tamponade. Successful urgent subxiphoid pericardiocentesis was performed; totally 2 ml of whitish fluid was collected, which resulted consistent to the composition of the hyperosmolar TPN solution infused.
Cardiac tamponade should be considered in any newborn with a peripherally inserted central catheter who presents with cardiorespiratory instability (bradycardia, cyanosis and metabolic acidosis), even when lines are believed to be placed correctly.
心包积液和心脏压塞是极低出生体重(ELBW)新生儿经皮插入中心静脉导管(PICL)使用过程中罕见但危及生命的并发症,报道的PICL置管发生率在0.07%至2%之间。及时诊断和心包穿刺已被证明可挽救生命。
该患者为出生体重620g的新生儿,在插入PICL后18天出现突发心脏不稳定,尽管导管尖端位置推测满意。经胸超声心动图显示严重心包积液并有心脏压塞的证据。成功进行了紧急剑突下心包穿刺;共收集到2ml白色液体,其成分与输注的高渗全胃肠外营养溶液一致。
任何使用外周插入中心导管且出现心肺不稳定(心动过缓、发绀和代谢性酸中毒)的新生儿,即使认为导管放置正确,也应考虑心脏压塞。
