Pain research

Taddio's clinical trials revealed short-term and long-term behaviour changes after neonatal circumcision. Taddio et al. (1997) concluded:

“

Infant analogue of a post-traumatic stress disorder triggered by a traumatic and painful event Although postsurgical central sensitisation (allodynia and hyperalgesia) can extend to sites of the body distal from the wound, suggesting a supraspinal effect, the long-term consequences of surgery done without anaesthesia are likely to include post-traumatic stress as well as pain. It is, therefore, possible that the greater vaccination response in the infants circumcised without anaesthesia may represent an infant analogue of a post-traumatic stress disorder triggered by a traumatic and painful event and re-experienced under similar circumstances of pain during vaccination. – Anna Taddio
