Abstract
To analyze the risk factors of catheter-related right jugular venous thrombosis in patients undergoing abdominal surgery. A total of 125 patients (18-90 years, ASA Ⅰ-Ⅲ) scheduled for abdominal surgery underwent right internal jugular in our study. Ultrasound-guided central venous catheterization were carried out before surgery and Doppler ultrasound examination were conducted daily postoperatively until the catheter was removed. The patients were divided into thrombosis positive or negative group based on the Doppler ultrasound examinations. General clinical data of all patients including name, gender, age, BMI, preoperative Caprini score, bleeding, duration of operation and anesthesia, were also collected. D-dimer test was performed on the third postoperative day. Of the 125 patients, 16(12.8%) were found to have catheter-related right internal jugular vein thrombosis. There were 16 cases (9 males and 7 females) in the thrombosis positive group, with an average age of (73±7) years old, body mass index (22.8±2.9) kg/m(2), and preoperative Caprini score (6.1±1.4).In the thrombosis negative group,among whom 72 were men and 37 were women. The average age of these patients was (66±11) years old, BMI was (22.6±2.9)kg/m(2), and preoperative Caprini score was (5.9±1.3).There was no statistical difference between the two groups regarding age, gender, BMI, preoperative Caprini score (0.05).The average operating time, anesthesia time, bleeding amount and D-dimer level on the third postoperative day were (189±46) min, (211±59) min, (288±96) ml,(3.4±1.6) mg/L in thethrombosis positive group, and (139±39) min, (171±46) min, (175±114) ml,(2.0±0.9) mg/L in the thrombosis negative group, respectively. Duration of surgery, bleeding amount and D-dimer level on the third postoperative day significantly affected the occurrence of catheter-related right internal jugular venous thrombosis (=10.768, 359.000, 390.000, 0.05), but no statistically significant differences in anesthesia time between the two groups.Logistic regression analysis screened out duration of surgery, bleeding amount and D-dimer level on the third postoperative day as risk factors for catheter-related right jugular venous thrombosis(10.037, 1.011, 3.274, 0.05). The high incidence of catheter-related right jugular venous thrombosis in patients undergoing abdominal surgery is closely related to intraoperative blood loss, operation time, D-dimer level on the third postoperative day and other factors.
