Intravenous nutrition has become a routine treatment method for premature infants. Peripherally inserted central catheter (PICC) has become a necessary access for preterm infants for parenteral nutrition therapy due to its advantages of safety, avoiding repeated puncture, and long indwelling time, is widely used. However, due to the relatively short superior vena cava in premature infants, rapid growth and development after birth, and frequent limb movements, ectopic catheter has become one of the main complications of PICC in premature infants, with an incidence of 6% to 10%. Compared with primary heterotopia, secondary heterotopia can cause complications such as fluid leakage, limb swelling, thrombosis, and pericardial effusion. Secondary heterotopia in premature infants may be asymptomatic or easily overlooked in the early stage, and may even be life-threatening when symptoms appear. This article reviews the early clinical manifestations, causes and preventive measures of secondary ectopic PICC catheter in premature infants, and provides a reference for preventing the occurrence of secondary ectopic PICC catheter in premature infants.展开更多
