Abstract：Objective: To explore the application value of chest radiography combined with body surface measurement in the measurement of central venous catheter (PICC) length in tumor patients. Methods: 60 cases of tumor patients requiring PICC catheter were selected from the oncology department of haian people's hospital of jiangsu province from May 2017 to April 2018, and were divided into the experimental group and the control group in 30 cases according to the random number table method. In the experimental group, the length of the PICC catheter was calculated by chest radiography combined with body surface measurement. In the control group, the length of the PICC catheter was calculated by body surface measurement formula alone. The accuracy rate of catheterization, length adjustment rate, incidence of ectopic catheter tip, incidence of postoperative complications and satisfaction of catheterization were compared between the two groups. Results: The accuracy rate of catheterization in the experimental group was 100% (30/30) higher than 86.7% (26/30) of the control group, P<0.05. The adjustment rate of catheter length and ectopic incidence of catheter tip in the experimental group were 6.7%(2/30) and 3.3% (1/30), respectively, lower than 30% (9/30) and 20% (6/30) of the control group, P<0.05. The complication rate of patients in the experimental group was 6.7% (2/30) lower than that of the control group (26.7% (8/30),P<0.05. Patients' satisfaction with catheterization in the experimental group was 96.7% (29/30) higher than that in the control group (24/30), P<0.05. Conclusion: Before the implantation of PICC in tumor patients, the application of chest radiography combined with body surface measurement can effectively improve the accuracy rate of catheterization, reduce the incidence of complications after catheterization in patients, and improve the satisfaction of patients, which is worthy of clinical application.
