Review Meta AnalysisSingle dose oral aspirin for acute postoperative pain in adults.
This review is an update of a previously published review in the Cochrane Database of Systematic Reviews on 'Single dose oral aspirin for acute pain'. Aspirin has been known for many years to be an effective analgesic for many different pain conditions. Although its use as an analgesic is now limited in developed countries, it is widely available, inexpensive, and remains commonly used throughout the world. ⋯ Aspirin is an effective analgesic for acute pain of moderate to severe intensity. High doses are more effective, but are associated with increased adverse events, including drowsiness and gastric irritation. The pain relief achieved with aspirin was very similar milligram for milligram to that seen with paracetamol. There was no change to the conclusions in this update.

Review Meta Analysis
Pharmacokinetics of fentanyl buccal tablet: a pooled analysis and review.
Fentanyl buccal tablet (FBT) is indicated for the treatment of breakthrough pain in patients who are already receiving and are tolerant to opioid therapy for underlying, persistent cancer pain. FBT is designed to enhance the rate and efficiency of absorption of fentanyl through the buccal mucosa. FBT was shown to be dose proportional from 100 to 1,300 μg. ⋯ However, plasma fentanyl concentration reached 80% of C(max) within 25 minutes and was maintained through 2 hours after administration. Based on the individual studies, bioequivalence was shown for sublingual and buccal tablet placement, and no significant effect of dwell time (duration of FBT presence in the oral cavity) was observed. The pharmacokinetic profile of FBT was characterized by rapid absorption, which is consistent with the rapid-onset efficacy profile of FBT observed in clinical studies.

Randomized Controlled Trial Meta Analysis Comparative Study
Remifentanil for labour analgesia: a meta-analysis of randomised controlled trials.
Remifentanil is a potent short-acting μ-opioid receptor agonist which is rapidly metabolised in the mother and fetus and may be ideal for labour analgesia. ⋯ During labour, remifentanil-PCA provided superior analgesia and higher patient satisfaction compared with pethidine with a comparable degree of adverse events. Epidural analgesia provided superior pain relief in comparison with remifentanil. Due to a low number of reported adverse events, the safety issue of remifentanil use in labour remains an open question that needs to be addressed in future trials.

Review Meta AnalysisDexamethasone for the prophylaxis of postoperative nausea and vomiting associated with neuraxial morphine administration: a systematic review and meta-analysis.
We performed a systematic review to assess the efficacy of dexamethasone in reducing postoperative nausea, vomiting (PONV), pruritus, and enhancing postoperative analgesia in patients receiving neuraxial anesthesia with neuraxial morphine. ⋯ Dexamethasone is an effective antiemetic for patients receiving neuraxial morphine for cesarean delivery and abdominal hysterectomy. In addition, the doses used for antiemetic prophylaxis enhanced postoperative analgesia compared with placebo. However, dexamethasone was not effective for the prophylaxis against neuraxial morphine-induced pruritus.
