An RCT of permanent-impregnated CSF shunts compared to non-impregnated shunts <strong>in</strong> adults<br />
and children showed a significant reduction <strong>in</strong> <strong>in</strong>fection rate when the impregnated device<br />
was used (10/60 versus 3/50, p=0.038). 184 The overall shunt <strong>in</strong>fection rate was high <strong>in</strong> this<br />
study. Two cohort studies of impregnated CSF shunts <strong>in</strong> children showed a 2.4-fold reduction<br />
<strong>in</strong> <strong>in</strong>fection rate <strong>in</strong> 145 patients compared to 208 historical controls, 185 and 1/31 patients<br />
with shunt <strong>in</strong>fection compared to 7/46 historical controls. 186 A six centre RCT of antibioticimpregnated<br />
external ventricular dra<strong>in</strong>s showed a 50% risk reduction <strong>in</strong> colonisation of the<br />
catheter (17.9% compared to 36.7% control catheters, p
