A line connecting the top of the iliac crests crosses the spinal axis at the L5-S1 level in neonates and infants up to one year of age and at the L4-L5 level in older children.5 The spinal cord ends approximately at L3 level at birth and at L1-L2 level in children over one year old. | A line connecting the top of the iliac crests crosses the spinal axis at the L5-S1 level in neonates and infants up to one year of age and at the L4-L5 level in older children.5 The spinal cord ends approximately at L3 level at birth and at L1-L2 level in children over one year old. | ||
The distance between the skin and the subarachnoid space is influenced by age – from 10 to 15mm in newborns.10 The distance between skin and subarachnoid space can be related to height or weight using the formulae: | The distance between the skin and the subarachnoid space is influenced by age – from 10 to 15mm in newborns.10 The distance between skin and subarachnoid space can be related to height or weight using the formulae: | ||
The subarachnoid space in newborns is very narrow (6 to 8mm) and successful lumbar puncture in this population requires great precision and avoidance of lateral deviation. | The subarachnoid space in newborns is very narrow (6 to 8mm) and successful lumbar puncture in this population requires great precision and avoidance of lateral deviation. | ||
