Clinical significance of intracavitary electrocardiographic localization in the prevention of PICC heterotopia in children with tumor.
Annals of Noninvasive Electrocardiology 2022 April 29
OBJECTIVE: To explore the clinical significance of intracavitary electrocardiogram positioning technology in preventing catheter ectopic position during peripherally inserted central catheter (PICC) catheterization in children with tumors.
METHODS: A retrospective analysis of the clinical data of 62 children who required PICC catheterization was performed. The intracavitary electrocardiogram (ECG) positioning technology was used during the tube placement of the child patients. After the tube was successfully placed, the chest radiograph was taken. The ECG positioning result was compared with the chest radiograph positioning result after the tube was inserted, and the sensitivity and specificity of the ECG positioning were calculated.
RESULTS: The intracavitary electrocardiogram results of 62 children with PICC catheters showed that 56 cases (90.32%) had characteristic P waves, and six cases (9.68%) had no characteristic P waves. The chest radiographs of 56 children with characteristic P wave showed that 33 cases (58.93%) of the catheter tip position was appropriate, 22 cases (39.29%) of the catheter tip was too deep, and 1 case was in a non-superior vena cava; six cases of chest radiographs of children with no characteristic P wave showed: one case was too deep at T8 level, one case was too shallow at T4 level, four cases were at non-superior vena cava, one case was contralateral internal jugular vein, two cases in the contralateral brachiocephalic vein, and one case was the contralateral subclavian vein.
CONCLUSION: Intracavitary ECG positioning assisted catheter placement in infants can effectively improve the accuracy of catheter tip position.
