Objective: This paper mainly discusses the correlation between PICC catheter length and body
surface measurement length. Methods: Choice in January 2021 to December 2021 in our hospital patients after
PICC catheter tube end position better patient 200 cases, the patients overall condition including patients need
catheter blood vessels, including the patients disease, for patient to vein, the middle on the left side of your veins
and venous puncture for 138 cases, In 62 cases, puncture was performed on the right important vein, median vein
and cephalic vein. Prior to catheterization, baseline measurements were taken, including height, chest
circumference, etc. After catheterization, chest X-ray should be taken to ensure that the end position of the PICC
tube is the sixth thoracic vertebra, and the catheter length should be known. Linear regression analysis was
performed. Results: After linear regression analysis, there was a certain relationship between the length of
catheterization and its height, chest circumference and length of certain measurement method. However, the
selection of puncture location does not affect the length of PICC catheter, and the regression equation of the length
of catheter at each puncture point can be performed. Conclusions:The specific height of the patient and the length
measured by one-word measurement should be taken into account when catheterization of PICC, and the length of
the CATHEterization of PICC can be adjusted according to the regression equation when choosing different
puncture points.
