Does perioperative ketamine have a role in the prevention of chronic postsurgical pain: the ROCKet trial

Abstract

Identifying operations and individuals with an increased risk of chronic postsurgical pain (CPSP) has led to significant interest in interventions with the potential to achieve primary prevention of this condition. Pharmacological prevention remains controversial with a Cochrane review identifying perioperative ketamine administration as the only intervention with possible benefit although, with only small, heterogeneous studies, the authors called for a large randomised controlled trial (RCT) to confirm the validity of this result. In response to these data, a group of researchers from Australia and Hong Kong designed the ROCKet trial – Reduction Of Chronic Post-surgical Pain with Ketamine,..
