Investigation on the related factors of central venous catheter congestion of ICU patients

Abstract

Objective To explore the influencing factors of central venous catheter blockage for patients in ICU to provide evidence for reducing the risk of catheter clogging and improving nursing quality. Methods A self-designed central venous catheter questionnaire and central venous catheter assessment table were used to investigate the catheterization of 209 patients in ICU. Results There were 39 clogging cases among the 209 cases of patients, the plugging rate was 18.66%.The results of multi-factor analysis showed that the risk factors for central venous catheter blockage were the femoral vein catheterization and central venous pressure >13 mmHg.The attachment of the attached device was the protective factor. Conclusions Central venous catheter jam of ICU patients closely related to the catheter site, the indwelling time, the type of liquid seal tube, additional device categories, micropump pumping speed, patient age, central venous pressure, prothrombin time, platelet number, type of infusion and puncture times.Among them, the femoral vein catheter and central venous pressure >13 mmHg are the risk factors for central venous catheter blockage, and the positive pressure infusion connector is the protective factor. In order to reduce the risk of central venous catheter blockage, the related factors should be taken into account for the clinical work.
