The Potential of Brain Rhythms in Predicting the Severity of Post-operative Pain
Topical Workshop
Chronic pain after surgery is common and affects up to 30% of patients undergoing surgeries such as mastectomy or thoracotomy. In two-thirds of the cases, this pain is neuropathic in nature. A significant predictor of whether an individual will develop chronic pain after surgery is the acute pain experienced immediately after surgery. If clinicians can pre-operatively identify which patients are highly pain-sensitive, they can take pre-emptive steps to minimize it and prevent its chronification. Amelie Grandjean will present recent data from her laboratory outlining the evidence that an individual's resting peak frequency of alpha activity, measured using EEG, can predict their sensitivity to pain after surgery. This can lead to point-of-care approaches for individualized risk prediction for acute and potentially chronic neuropathic, postoperative pain.
