目的 探讨脐动脉置管术在危重新生儿治疗中的应用.方法 30例危重新生儿接受脐动脉置管术,术前估计置管长度,将导管缓慢插入脐动脉,当导管插入达到预计长度时,用预充生理盐水的注射器回抽及X线检查以明确导管处于脐动脉内.结果 30例患儿导管留置时间为2～7 d,平均4 d.2例患儿出现发热,抗感染治疗有效;其余28例无出血、动脉栓塞、坏死性肠炎等并发症发生.结论 脐动脉置管有利于危重新生儿病情监测与治疗,具有重要的临床意义.%Objective To explore the application of umbilical artery catheterization in the treatment of severe neonatal illness. Methods 30 neonates with severe illness accepted umbilical artery catheterization. The length of insertion of umbilical artery cathe ter was estimated before operation,and then the catheter was slowly inserted to the umbilical artery. When it was advanced to the estimated length, withdrawing syringe pre-filled with saline and X-ray examination were performed to confirm its position in umbilicai artery. Results Indwelling time of catheters of 30 cases were 2- 7 days,with average of 4 days. 2 cases of fever occurred and were treated effectively with anti-infective agents. The remaining 28 neonates showed no complications such as hemorrhage, arterial embolization and necrotic enteritis. Conclusion Umbilical artery catheterization is conducive to monitoring and treatment of severe neonatal illness, with important clinical significance.
