Abstract

This paper aimed to explore the risk factors of peripherally inserted central catheter (PICC) related thrombosis (PICC-RT) in tumor patients mediated by ultrasound images under minimum variance (MV) algorithm and put forward the corresponding nursing intervention methods based on the risk factors. The smoothing algorithm, diagonal loading algorithm, and coherence factor algorithm were optimized via MV algorithm. The optimized algorithm was compared with other algorithms to analyze its image quality and image processing speed. Literature retrieval was conducted to analyze the risk factors of PICC-RT in tumor patients. Tumor patients who received PICC for chemotherapy in the hospital from June 2018 to December 2019 were selected. Patients who were accepted before the experiment were taken as the controls, and there were control group (89 cases) and observation group (91 cases). Exercise, average flow rate of axillary vein per unit time, and PICC-RT were compared between the two groups. The results showed that the optimized algorithm (MV-N) had better image resolution, image contrast, and calculation speed than other algorithms. Gender, body mass index (BMI), pathological type, clinical stage, disease history, fibrinogen (FIB), and use of anticoagulant drugs were risk factors for PICC-RT in tumor patients. The number of PICC-RT and complications in the observation group was notably lower in contrast to the control group ( P < 0.05 ). It indicated that a novel algorithm was successfully established, which could increase the ultrasonic image quality and computing speed, and upper limb exercise could reduce the incidence of PICC-RT and its complications in tumor patients.

Highlights

peripherally inserted central catheter (PICC) is a catheter that is inserted into the central vein through peripheral venipuncture to provide patients with safe and durable venous access [1]
PICC-RT refers to the thrombosis formed on the inner wall of the catheterized vein or the outer wall of the catheter caused by PICC, which is easy to cause pulmonary embolism
minimum variance (MV) and MVFB fluctuated greatly with the increase of length/number of elements (L/M) value. e imaging contrast under these seven algorithms was analyzed (Figure 3), and the results showed that MV-N and MV-GCF were less affected by the L/M value

Summary

Introduction

PICC is a catheter that is inserted into the central vein through peripheral venipuncture to provide patients with safe and durable venous access [1]. PICC delivers chemotherapeutic drugs directly to the superior vena cava, reducing the damage to blood vessels caused by irritating drugs [2]. PICC-RT refers to the thrombosis formed on the inner wall of the catheterized vein or the outer wall of the catheter caused by PICC, which is easy to cause pulmonary embolism. About 15% of PICC-RT patients will develop pulmonary embolism [3]. Studies have pointed out that upper limb exercise can reduce the incidence of PICC-RT, and inappropriate upper extremity movement may cause other catheterrelated complications [4]
