Chronic Pain Dynamic Psychophysical Tests and Genetic Screening

Prediction of Chronic Pain in the Asian Population- Comprehensive Programme Encompassing Dynamic Psychophysical Tests and Genetic Screening to Determine and Prevent Persistent Post-caesarean Pain

Incidence and risk factors for persistent post surgical pain after Caesarean section are investigated. Demographic, psychophysical testing and genetic screening factors are performed in the perioperative period. Phone survey is performed to investigate the incidence of persistent post surgical pain after Caesarean section.

Persistent post surgical pain after Caesarean section may lead to functional limitation and pain during activities of daily living. Demographic factors, psychophysical factors (mechanical temporal summation, diffuse noxious inhibitory control, state trait anxiety inventory) and genetic screening are used to predict the association with persistent post surgical pain. Phone survey follow up is performed to investigate the incidence of persistent post surgical pain and functional limitations due to pain experienced.

Inclusion Criteria:

• Women undergoing spinal anaesthesia for Caesarean section

Exclusion Criteria:

• Failed spinal anaesthesia, Unable to perform psychophysical testing.
