Meta Analysis Comparative StudyIntrathecal opioids versus epidural local anesthetics for labor analgesia: a meta-analysis.
Some anesthesiologists contend that intrathecal opioid administration has advantages over conventional epidural techniques during labor. Randomized clinical trials comparing analgesia and obstetric outcome using single-injection intrathecal opioids versus epidural local anesthetics suggest that intrathecal opioids provide comparable analgesia with few serious side effects. This meta-analysis compared the analgesic efficacy, side effects, and obstetric outcome of single-injection intrathecal opioid techniques versus epidural local anesthetics in laboring women. ⋯ Published studies suggest that intrathecal opioids provide comparable early labor analgesia when compared with epidural local anesthetics. Intrathecal opioid administration results in a greater incidence of pruritus. The choice of technique does not appear to affect the method of delivery.

Children frequently present to the accident and emergency (A&E) department in pain. Most presentations are acute, but children with pain of longer duration also present. Children also often undergo painful procedures in A&E in the process of diagnosis or treatment. ⋯ Part II: Pharmacological methods of paediatric analgesia. Part III: Non-pharmacological methods of pain control and anxiolysis. Part IV: Paediatric sedation in accident and emergency.

Patient-controlled analgesia (PCA) has become standard procedure in the clinical treatment of pain. Its widespread use in patients with all kinds of diseases opens a variety of possible interactions between analgesics used for PCA and other drugs that might be administered concomitantly to the patient. Many of these drug interactions are of little clinical importance. ⋯ The same is true for the opioid-sparing effects of coadministered non-opioid analgesics. Antidepressants, anticonvulsants or alpha2-adrenoreceptor agonists have also been shown to exert additive analgesic effects when administered together with an opioid. Inconsistent findings, however, are reported regarding the treatment of patients with opioid-induced nausea and sedation, since coadministration of antiemetics either increased or decreased the respective adverse effects or revealed additional unwanted drug effects.

Randomized Controlled Trial Clinical TrialMultimodal analgesia and intravenous nutrition preserves total body protein following major upper gastrointestinal surgery.
This study examined whether perioperative multimodal analgesia (MMA) improves the effectiveness of intravenous nutrition (IVN) as a means of preventing protein wasting following major upper abdominal surgery (UAS). The MMA regimen utilized combined epidural opioid/local anesthetic and the systemic nonsteroidal anti-inflammatory drug (NSAID) ketorolac for 48 hours. ⋯ In conclusion, we have shown that the combination of MMA and IVN prevents protein loss and improves pain control after major UAS. Our results suggest that after UAS, MMA significantly reduced pain and, in combination with IVN, preserves total body protein and fat. This is the first direct evidence of such effects associated with a commonly used multimodal regimen.

Meta Analysis
Examining the evidence in anesthesia literature: a survey and evaluation of obstetrical postdural puncture headache reports.
To describe a bibliographic database on the literature of postdural puncture headache (PDPH) in the obstetrical population, to describe the research architecture in this field, and to evaluate the quality of case-control studies, cohort studies, and controlled clinical trials on PDPH. ⋯ Although the amount of research on PDPH in parturients is increasing, use of optimal study designs and improvement in methodology is needed.
