Osteoarthritis (OA) is the most common form of arthritis. Published guidelines and expert opinion are divided over the relative role of acetaminophen (also called paracetamol or Tylenol) and non-steroidal anti-inflammatory drugs (NSAIDs) as first-line pharmacologic therapy. The comparative safety of acetaminophen and NSAIDs is also important to consider. This update to the original 2003 review includes nine additional RCTs. ⋯ The evidence to date suggests that NSAIDs are superior to acetaminophen for improving knee and hip pain in people with OA. The size of the treatment effect was modest, and the median trial duration was only six weeks, therefore, additional considerations need to be factored in when making the decision between using acetaminophen or NSAIDs. In OA subjects with moderate-to-severe levels of pain, NSAIDs appear to be more effective than acetaminophen.

Review Meta AnalysisEpidural pain relief versus systemic opioid-based pain relief for abdominal aortic surgery.
Epidural analgesia offers greater pain relief compared to systemic opioid-based medications, but its effect on morbidity and mortality is unclear. ⋯ Epidural analgesia provides better pain relief (especially during movement) for up to three postoperative days. It reduces the duration of postoperative tracheal intubation by roughly 20%. The occurrence of prolonged postoperative mechanical ventilation, overall cardiac complication, myocardial infarction, gastric complication and renal complication was also reduced by epidural analgesia, especially thoracic. However, current evidence does not confirm the beneficial effect of epidural analgesia on postoperative mortality and other types of complications.

Review Meta AnalysisInterventions for paracetamol (acetaminophen) overdose.
Poisoning with paracetamol (acetaminophen) is a common cause of hepatotoxicity in the Western World. Inhibition of absorption, removal from the vascular system, antidotes, and liver transplantation are interventions for paracetamol poisoning. ⋯ Our results highlight a paucity of randomised trials on interventions for paracetamol overdose. Activated charcoal seems the best choice to reduce absorption. N-acetylcysteine should be given to patients with overdose but the selection criteria are not clear. No N-acetylcysteine regime has been shown to be more effective than any other. It is a delicate balance when to proceed to liver transplantation, which may be life-saving for patients with poor prognosis.

Meta AnalysisA qualitative systematic review of peri-operative dextromethorphan in post-operative pain.
The N-methyl-D-aspartate (NMDA) receptor antagonist, dextromethorphan (DM), has received interest as an adjunctive agent in post-operative pain management. Clinical trials have been contradictory. This systematic review aims to evaluate the available literature examining the analgesic efficacy of DM in post-operative patients. ⋯ Based on the studies available, DM has the potential to be a safe adjunctive agent to opioid analgesia in post-operative pain management, but the consistency of the potential opioid-sparing and pain-reducing effect must be questioned. Consequently, it is not possible to recommend dose regimens or routine clinical use of DM in post-operative pain. The route of administration may be important for the beneficial effect.

Review Meta AnalysisPatient controlled opioid analgesia versus conventional opioid analgesia for postoperative pain.
Patients may control postoperative pain by self-administration of intravenous opioids using devices designed for this purpose (patient controlled analgesia or PCA). A 1992 meta-analysis by Ballantyne found a strong patient preference for PCA over conventional analgesia but disclosed no differences in analgesic consumption or length of postoperative hospital stay. Although Ballantyne's meta-analysis found that PCA did have a small but statistically significant benefit upon pain intensity, Walder's review in 2001 did not find a significant differences in pain intensity and pain relief between PCA and conventionally treated groups. ⋯ This review provides evidence that PCA is an efficacious alternative to conventional systemic analgesia for postoperative pain control.
