Objective: This study intended to analyze hazardous factors of venous thrombosis by comparing the effect of different doses of heparin sodium injection on the incidence rate of peripherally inserted central catheter (PICC)-related venous thrombosis in non-small cell lung carcinoma (NSCLC) patients during postoperative chemotherapy.
Methods: 425 NSCLC patients who received PICC catheterization in Cancer Hospital Chinese Academy of Medical Sciences, Shenzhen Hospital from July 2019 to July 2021 were collected. Based on their different pathological types, patients were given two different chemotherapy regimens: pemetrexed+cisplatin or paclitaxel+cisplatin. Patients were grouped according to the different doses of heparin sodium injection adopted. Control group (n = 140). Catheters were sealed with 10 mL saline only. Group I (n = 142). In addition to routine maintenance with normal saline, 2 mL of 10 IU/mL heparin sodium injection was sealed in the catheters under positive pressure every time after catheterization. Group II (n = 143). In addition to routine maintenance with normal saline, 5 mL of 10 IU/mL heparin sodium injection was sealed in the same manner as Group I. The baseline characteristics of the three groups of patients were compared by statistical means. Doppler ultrasonography was applied to check the venous thrombosis. The hazardous factors of venous thrombosis were analyzed through correlation analysis and binary logistic regression method.
Results: The incidence rates of thrombosis in the control group, Group I, and Group II were 20.00%, 7.04%, and 2.09%, respectively, with statistically significant differences (P < 0.01). Additionally, through the collinear correlation analysis of baseline characteristics, a significant correlation between the dosage of heparin sodium injection and the incidence of thrombosis was observed (P < 0.05), but there were no significant differences between other baseline data and the incidence of thrombosis (P > 0.05). Binary logistic regression analysis revealed that postoperative use of heparin sodium injection (Group I: OR = 0.312; P = 0.003; Group II: OR = 0.082, P < 0.001) was a protective factor for preventing thrombosis. In addition, the thromboprophylaxis effect of Group II was better than that of Group I. No serious adverse reactions were found in safety analysis.
Conclusion: Heparin sodium could significantly lower the incidence rate of PICC-related venous thrombosis in NSCLC patients during postoperative chemotherapy. Heparin sodium injection is safe enough to be promoted among PICC patients with a high risk of venous thrombosis.Reference:
