Subclavian vein catheterization and infection. A bacteriological study of 130 catheter insertions.

AbstractThe nature, frequency and significance of bacterial growths from catheter cultures in 130 subclavian vein catheterizations were studied. 64 catheters were inserted in non-infected patients (group A), and 66 catheters in infected patients (group B). No relevant catheter growth was observed in group A. In a part of group B (58 catheters), comparable with group A as regards duration of catheterization, relevant growth was observed in 6 cases (10%) and probably relevant growth in 11 cases (19%). The difference between the groups studied is significant (P < 0.05). In the total group B, relevant growth was observed in 9 cases (14%) and probably relevant growth in 14 cases (21%). The duration of catheterization in the 9 cases with relevant growth was significantly longer than in the other 57 cases (P < 0.01). In 2 of the 9 cases, despite adequate antibiotic therapy, sepsis was not eliminated until catheters were removed. It is concluded that the risk of infection when percutaneous subclavian catheters ar...
