RESUMO
Objective:To explore the types of venous access, indwelling time and the correlation with catheter-related bloodstream infection (CRBSI) of very and extremely low birth weight infants (VLBW & ELBW) in NICU.Methods:The self-designed venous access data collection form was used to collect the venous access data of VLBW & ELBW infants who were admitted to NICU of Children′s Hospital of Fudan University from January to December 2019. SPSS 22.0 software was used for data analysis, description and binary Logistic regression analysis.Results:A total of 218 cases were collected, including 9 cases of peripheral intravenous (PIV), 30 cases of PIV+ umbilical vein catheter (UVC), 43 cases of PIV+PICC, 136 cases of PIV+UVC+PICC. The average indwelling time of UVC was 6 days, the average indwelling time of PICC was 22 days. There were 23 cases (10.55%) got CRBSI and 195 cases (89.45%) without CRBSI. Binary Logistic regression analysis showed that birth weight ( OR=1.003, 95% CI 1.000-1.006, P<0.05) and combination form of venous access ( OR=0.139, 95% CI 0.023-0.834, P<0.05) of VLBW & ELBW infants were associated with CRBSI. Conclusions:In NICU, PIV, UVC and PICC are the three main ways to indwell venous access for VLBW & ELBW infants. The occurrence of CRBSI is closely related to the type and combination of indwelling venous access.
