We observed hyponatraemia in several preterm children treated with a ventricular access device (Rickham reservoir)1 after intraventricular haemorrhage (IVH)2 and serial liquor puncture to drain liquor. To rule out a connection, we retrospectively investigated the data of all preterm children (23–32 weeks of gestational age) treated at the University Children’s Hospital of Cologne with a ventricular access device during 1996–1999 (n = 16).

Sixteen of 480 preterm infants …
