Figure 42-6. Approximate volume of cerebrospinal fl
uid (CSF) relative to weight and age. Note that
preterm and full-term infants have a much greater
CSF volume relative to weight than a child or adult;
this may account in part for the increased dose
(mg/kg) of local anesthetic required in infants to
produce a successful subarachnoid block
