Individual differences in acute pain-induced endogenous analgesia predict time to resolution of postoperative pain in the rat.

Peters C, Hayashida K, Suto T, Houle T, Aschenbrenner C, Martin T, Eisenach J (2015) Individual differences in acute pain-induced endogenous analgesia predict time to resolution of postoperative pain in the rat. Anesthesiology 122:895-907. doi: 10.1097/ALN.0000000000000593

Summary: The authors investigated the relationship between preoperative Conditioned Pain Modulation (CPM) and the time course of recovery from surgery. CPM was evaluated using forepaw capsaicin injections into rats. During the study, lesioned rats received 5-μg intrathecal injections of anti-DBH-SAP (Cat. #IT-03), followed 14 days later by a partial L5 spinal nerve ligation surgery. Mouse-IgG-SAP (Cat. #IT-18) was used as a control. CPM was partially blocked in the lesioned animals, suggesting descending noradrenergic signaling is important in the time course of recovery from surgery.
