Clinical observation and experimental study on Kangfuxin fluid in treating indwelling needle-related phlebitis

Objective To investigate the therapeutic effect of Kangfuxin Fluid on indwelling needle-related phlebitis by observation of clinical samples and pharmacological study.Methods Eighty-five patients with indwelling needle-related phlebitis in the neurosurgery department of a Grade A hospital in Shanxi Province from June 2019 to November 2021 were randomly divided into the study group(43 cases)and the vehicle group(42 cases).Patients in the study group were treated with KFX,and patients in the control group were treated with hydrocolloid dressing.The time for symptoms(such as redness and pain)to disappear was recorded.The effect of tissue repair was evaluated by the fin crosscutting model and the anti-inflammatory effect was evaluated by the inflammatory models.Q-PCR assay was used to detect the mRNA expression levels of IL-6 and TNF-αin LPS-stimulated zebrafish.The effect on promoting angiogenesis was evaluated by the inter-segmental blood vascular defect model of zebrafish.Results The curative effect of the study group was better than the control group.The pain resolution time and the swelling resolution time in the study group were(1.67±0.90)d and(2.25±0.92)d,respectively,shorter than those in the control group(P<0.05).KFX can improve the ISV index,increase the regeneration length of the fin,inhibit the migration of neutrophils in three inflammatory models and reduce the mRNA expression levels of IL-6 and TNF-αin LPS-stimulated zebrafish.Conclusion KFX exerts great clinical efficacy in the treatment of indwelling needle-induced phlebitis which may be associated with inflammation inhibition,angiogenesis promotion,and tissue repair.
