The distance from the skin to the epidural space in a Chinese patient population.
The inter-relationship between age, height, weight and distance from the skin to the epidural space correlated with the patient's weight (r = 0.52, F = 23.96, P less than 0.001), and showed no correlation with patient's height (r = 0.18, F = 0.04, P greater than 0.05) or age (r = 0.13, F = 1.88, P greater than 0.05). The epidural space was found at a depth range of 3-7 cm, and 60% of patients had a depth of 4-5 cm. The results may be useful as a guideline for successful epidural blocks.
