- •
Changes in position alter the dimension of the dural sac in late pregancy.
- •
The axial section area of the dural sac is smaller in the supine than the lateral position.
- •
The transverse diameter of the dural sac is smaller in the supine than the lateral position.
- •
These changes may affect the spread of spinal anesthesia when changing patient position.
