Impact of four kinds of limit body position to PICC catheter tip position

Abstract

Objective To find the body maximum scope of activities on patients with PICC catheter, in order to do better health education for patients after catheterization mission. Methods We chose 75 patients who accepted the catheter at right limb for the first time, with the location of the catheter tip in the superior vena cava lower 1/3, superior vena cava and right atrium in 3-4 cm. We defined arms natural prolapse as the 0 position, which was the controlled position. Position 1 referred to the fingers touching the back to the highest, position 2 as shoulder joint rear protraction to the biggest angle, position 3 as shoulder joint anteflexion to the biggest angle, position 4 as shoulder joint adduction to the biggest angle. After the 4 kinds of position, X-ray was taken, the highest level in the subclavian vein pipe as the zero line, computer software was used to measure the each asana PICC tip from zero distance. Results Tips of PICC catheters moved up when taking position 1 and 2, whereas tips moved down when taking position 3 and 4. Position 1, 2, 3 and 4 moved (-26.18±11.32) , (-16.09±10.97), (24.36±19.05) , (36.64±22.48) mm respectively compared with the controlled position(P<0.01). Conclusions According to 4 kinds of position which induced the PICC tip changes to guide the patients daily actions could ensure the quality of life of patients with PICC and the use value of catheter.
