Abstract
- Background: Subarachnoid hemorrhage (SAH) has been recognized as a risk factor for ventriculostomy-related infections (VRI). In addition to the hemorrhagic cerebrospinal fluid (CSF), the potential need for prolonged catheterization may contribute to the increased CSF infection rate in this population. The use of antibiotic-impregnated catheters (AIC) has effectively reduced the risk of VRI. Herein, we examined specifically the impact of systematic insertion of AIC on the timing of CSF infections in SAH patients. Methods: Retrospective review of patients admitted between April 2006 to March 2009 with a non-traumatic SAH who required an external ventriculostomy. Only patients with AIC were included. A meningitis or ventriculitis was diagnosed according to the published criteria of the Center for Disease Control and Prevention. Results: This study includes 75 patients in which 97 drains were inserted. Seven infections (7/75 = 9.3%) occurred over 1,024 drainage days (DD), resulting in a rate of 6.8 infections/1,000 DD. The mean drainage time was 15.4 days in the infected AIC group compared with 10.2 days in the non-infected AIC group. No infection occurred before day 9 of drainage and 71% (5/7) occurred after more than 2 weeks of drainage. The observed timing of infections is delayed in comparison with that reported in series using non-AIC, which typically occur prior to the 10th day of drainage. Conclusions: In the high-risk population of non-traumatic SAH, the use of AIC delays the occurrence of infection compared with that reported with non-antibiotic-impregnated catheters. This may orient management strategies in SAH patients requiring a ventriculostomy. [ABSTRACT FROM AUTHOR]
