Randomized Controlled Trial Comparative Study
[Postoperative analgesia with intraarticular local anesthetic bupivacaine and alpha2-agonist clonidine after arthroscopic knee surgery].
To evaluate the efficacy of intraarticular 0.5% 20 ml bupivacaine and compound of bupivacaine with alpha2-agonist clonidine for postoperative analgesia after arthroscopic knee surgery. A total of 48 patients, scheduled for knee arthroscopy, were enrolled in the study. Patients were randomly assigned to three different groups: placebo (group C), and two experimental groups that received one of the following double-blinded intraarticular solutions: 0.5% 20 ml of bupivacaine (group B) and 0.5% 20 ml of bupivacaine with l microg/kg of clonidine (group B+C). Patients were asked to evaluate on a visual analogy scale (VAS) the intensity of pain at rest and during motion, satisfaction with postoperative analgesia. Side effects and requirements for supplemental analgetics were recorded at the same time. ⋯ The compound of intraarticular bupivacaine and clonidine suppresses pain better than intraarticular injection of bupivacaine or use of usual systemic analgetics (p<0.05). Intraarticular analgesia assures satisfaction with anesthesiologic procedure.

Review Meta AnalysisPatient controlled intravenous opioid analgesia versus continuous epidural analgesia for pain after intra-abdominal surgery.
There are two common techniques for postoperative pain control after intra-abdominal surgery: patient-controlled analgesia (PCA) with intravenous opioids and continuous epidural analgesia (CEA). It is uncertain which method has better pain control and fewer adverse effects. ⋯ CEA is superior to opioid PCA in relieving postoperative pain for up to 72 hours in patients undergoing intra-abdominal surgery, but it is associated with a higher incidence of pruritus. There is insufficient evidence to draw comparisons about the other advantages and disadvantages of these two methods of pain relief.

Review Meta AnalysisNon-steroidal anti-inflammatory drugs and perioperative bleeding in paediatric tonsillectomy.
Nonsteroidal anti-inflammatory drugs (NSAIDs) are used for pain relief following tonsillectomy in children. However, as they inhibit platelet aggregation and prolong bleeding time, they could cause increased perioperative bleeding. The overall risk remains unclear. ⋯ NSAIDs did not cause any increase in bleeding requiring a return to theatre. There was significantly less nausea and vomiting when NSAIDs were used compared to alternative analgesics.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialCombination oxycodone 5 mg/ibuprofen 400 mg for the treatment of pain after abdominal or pelvic surgery in women: a randomized, double-blind, placebo- and active-controlled parallel-group study.
The sensation of pain arises from both central and peripheral sites, and inflammation may be one of its underlying causes. Combination therapy with analgesic agents having multimodal mechanisms of action and complementary pharmacokinetic properties enhances pain relief by addressing the different pathways of pain while limiting individual drug doses and, therefore, the potential for adverse effects caused by any single agent. Oxycodone and ibuprofen each have been used effectively as monotherapy and in other combinations for the treatment of acute pain; a fixed combination of these analgesics may improve pain relief in the setting of abdominal or pelvic surgery, where trauma and any resultant inflammation may be present at the same time. ⋯ In this population of women who had undergone abdominal or pelvic surgery, the combination of oxycodone 5 mg/ibuprofen 400 mg was significantly more effective than either agent alone or placebo in the treatment of moderate to severe postoperative pain.

Review Comparative Study
Ketamine and postoperative pain--a quantitative systematic review of randomised trials.
Ketamine, an N-methyl-D-aspartate receptor antagonist, is known to be analgesic and to induce psychomimetic effects. Benefits and risks of ketamine for the control of postoperative pain are not well understood. We systematically searched for randomised comparisons of ketamine with inactive controls in surgical patients, reporting on pain outcomes, opioid sparing, and adverse effects. ⋯ The highest risk of hallucinations was in awake or sedated patients receiving ketamine without benzodiazepine; compared with controls, the odds ratio (OR) was 2.32 (95%CI, 1.09-4.92), number-needed-to-harm (NNH) 21. In patients undergoing general anaesthesia, the incidence of hallucinations was low and independent of benzodiazepine premedication; OR 1.49 (95%CI 0.18-12.6), NNH 286. Despite many published randomised trials, the role of ketamine, as a component of perioperative analgesia, remains unclear.
