Nonsteroidal anti-inflammatory drugs in the perioperative period: current controversies and concerns.
Nonsteroidal anti-inflammatory drugs (NSAIDs) and cyclooxygenase (COX)-2-specific inhibitors provide significant analgesic and opioid-sparing benefits. However, these analgesics are commonly avoided owing to concerns of potential adverse effects. The evidence for NSAID-related adverse effects is conflicting and of poor quality, and these analgesics are safer than what has been implied. Thus, it is imperative that NSAIDs or COX-2-specific inhibitors are administered routinely unless there are well-founded contraindications.

Spinal cord stimulation (SCS) is widely accepted as a useful treatment for patients with intractable chronic pain. However, its effectiveness varies between individuals. Therefore, a tool for evaluating its effectiveness in advance is eagerly awaited. We examined whether resting-state functional magnetic resonance imaging as a diagnostic and prognostic tool can predict responsiveness to SCS. ⋯ For patients with intractable chronic pain, functional connectivity between the middle anterior cingulate cortex and precuneus/posterior cingulate cortex is a promising candidate biomarker to estimate responsiveness to spinal cord stimulation before treatment.
