We have studied the depth of epidural space in 586 children who had lumbar epidural block as part of their anaesthetic management. The mean depth of epidural space in neonates was 1 cm (SD 0.2, range 0.4-1.5 cm). The depth of epidural space in older infants and children correlated significantly with age and weight with regression equations of depth (cm) = 1 + 0.15 x age (years) and depth (cm) = 0.8 + 0.05 x weight (kg) respectively.
