Review Meta AnalysisOpioids for neonates receiving mechanical ventilation: a systematic review and meta-analysis.
To evaluate the effect of opioid analgesics, compared to placebo, no drug, or other non-opioid analgesics or sedatives, on pain, duration of mechanical ventilation, mortality, growth and neurodevelopmental outcomes in newborn infants on mechanical ventilation. ⋯ There is insufficient evidence to recommend routine use of opioids in mechanically ventilated newborns. Opioids should be used selectively, when indicated by clinical judgment and evaluation of pain indicators. If sedation is required, morphine is safer than midazolam.

Review Meta Analysis
Outcomes associated with opioid use in the treatment of chronic noncancer pain in older adults: a systematic review and meta-analysis.
This systematic review summarizes existing evidence regarding the efficacy, safety, and abuse and misuse potential of opioids as treatment for chronic noncancer pain in older adults. Multiple databases were searched to identify relevant studies published in English (1/1/80-7/1/09) with a mean study population age of 60 and older. Forty-three articles were identified and retained for review (40 reported safety and efficacy data, the remaining 3 reported misuse or abuse outcome data). ⋯ Abuse and misuse behaviors were negatively associated with older age. In older adults with chronic pain and no significant comorbidity, short-term use of opioids is associated with reduction in pain intensity and better physical functioning but poorer mental health functioning. The long-term safety, efficacy, and abuse potential of this treatment practice in diverse populations of older persons remain to be determined.

Review Meta Analysis
Impact of intravenous lidocaine infusion on postoperative analgesia and recovery from surgery: a systematic review of randomized controlled trials.
Postoperative pain continues to be inadequately managed. While opioids remain the mainstay for postoperative analgesia, their use can be associated with adverse effects, including ileus, which can prolong hospital stay. A number of studies have investigated the use of perioperative intravenous lidocaine infusion for improving postoperative analgesia and enhancing recovery of bowel function. ⋯ In conclusion, intravenous lidocaine infusion in the perioperative period is safe and has clear advantages in patients undergoing abdominal surgery. Patients receiving lidocaine infusion had lower pain scores, reduced postoperative analgesic requirements and decreased intraoperative anaesthetic requirements, as well as faster return of bowel function and decreased length of hospital stay. Further studies are needed to assess whether lidocaine has a beneficial effect in patients undergoing other types of surgery and to determine the optimum dose, timing and duration of infusion of lidocaine in this setting.

Review Meta Analysis Comparative Study
Comparative efficacy and harms of duloxetine, milnacipran, and pregabalin in fibromyalgia syndrome.
Duloxetine (DLX), milnacipran (MLN), and pregabalin (PGB) are the only drugs licensed by the US Food and Drug Administration (FDA) for fibromyalgia syndrome (FMS). Evidence on the comparative benefits and harms is still accruing. The authors searched MEDLINE, SCOPUS, Cochrane Central Register of Controlled Trials, and sought unpublished data from the databases of FDA, US National Institutes for Health, and Industry through May 2009 for randomized controlled trials. Outcomes of interest were symptom reduction (pain, fatigue, sleep disturbance, depressed mood, reduced health-related quality of life), and adverse events. 17 studies with 7,739 patients met the inclusion criteria. The 3 drugs were superior to placebo except DLX for fatigue, MLN for sleep disturbance, and PGB for depressed mood. Adjusted indirect comparisons indicated no significant differences for 30% pain relief and dropout rates due to adverse events between the 3 drugs. Significant differences in average symptom reduction were found: DLX and PGB were superior to MLN in reduction of pain and sleep disturbances. DLX was superior to MLN and PGB in reducing depressed mood. MLN and PGB were superior to DLX in reducing fatigue. The risk of headache and nausea with DLX and MLN was higher compared with PGB. The risk of diarrhea was higher with DLX compared to MLN and PGB. There is evidence for the short-term (up to 6 months) efficacy of DLX, MLN, and PGB. Differences with regard to the occurrence of the key symptoms of FMS and to drug-specific adverse events may be relevant for the choice of medication. ⋯ This article presents comparative data on the efficacy and harms of duloxetine, milnacipran, and pregabalin in fibromyalgia syndrome. The results can help clinicians in choosing medication since the 3 drugs have different effects on the key symptoms of fibromyalgia syndrome and differences in side effects, contraindications, and warnings.

To determine the risk: benefit of paracetamol combined with caffeine in the short-term management of acute pain conditions. ⋯ Paracetamol/caffeine (1,000 mg/130 mg) is effective and safe for use in acute management of pain. The hepatotoxicity of overdoses of paracetamol results from its oxidative metabolism, caffeine does not produce any increase in oxidative metabolism of therapeutic concentrations of paracetamol.
