An intraventricular catheter may become infected, resulting in ventriculitis. The risk of this complication is affected by a number of factors.

Factors associated with increased risk of infection:

(1) failure to use proper sterile technique at the time of insertion (sterile supplies, barrier, masks, gowns and caps)

(2) prolonged placement (> 11 days)

(3) CSF leakage

(4) frequent manipulation including irrigation and sampling


Factors associated with reduced risk of infection:

(1) use of antibiotic-impregnated catheters

(2) changing the dressing every 48 hours

(3) training the nurses in how to properly change the dressing
