Another review of research finds epidurals and other forms of spinal anesthesia appear to be safer than previously thought.
Epidurals are often used for women in labor and in some operations.
Researchers looked at complications from epidurals and found the risk for permanent harm was 1 in 23,000. And even lower in most cases.
The risk for permanent injury for expectant mothers was 1 in 80,000.
Patients undergoing surgery had a slightly higher risk, because they tended to be older and more frail.
