Randomized Controlled Trial Clinical TrialEfficacy of pre-incisional bupivacaine infiltration on postoperative pain relief after appendectomy: prospective double-blind randomized trial.
Pain is the most undesirable and threatening experience for surgical patients. This study aims to determine the efficacy of pre-incisional analgesic bupivacaine infiltration (preemptive analgesia) on postoperative pain relief after appendectomy. A prospective randomized double-blinded study was conducted on 123 patients aged 13-45 years with a preoperative and-postoperative diagnosis of acute appendicitis admitted to Siriraj Hospital, Bangkok, from January to May 2002. ⋯ So were the total number of morphine injections and the amount of morphine used postoperatively. The pain reduction could be due to interruption of inflammatory or pain mediator cascades that normally occur during an operation. This study showed that pre-incisional bupivacaine infiltration is an effective and simple method of reducing postoperative pain for patients undergoing appendectomy.

Randomized Controlled Trial Clinical TrialPropacetamol and diclofenac alone and in combination for analgesia after elective tonsillectomy.
Diclofenac and paracetamol have different mechanisms and sites of action. Therefore, we tested if their combination is more effective for analgesia after tonsillectomy than either drug alone with respect to rescue analgesic consumption and visual analog scale values. ⋯ Combined treatment with propacetamol and diclofenac with the dosages used provided clinically only a minor advantage over monotherapy with propacetamol or diclofenac with respect to postoperative analgesia or the incidence of side-effects in adult tonsillectomy patients.

Randomized Controlled Trial Comparative Study Clinical TrialPain relief after arthroscopic knee surgery--intraarticular sufentanil vs morphine.
Prevention of postoperative pain by injecting opioid into the knee joint is believed to support the hypothesis of peripheral opioid receptor activation in inflammation. Main outcomes were reduction of pain intensity and need for supplementary analgesics. The aim of the present study was to evaluate the analgesic effects of intraarticular sufentanil in comparison with morphine, following arthroscopic procedures of knee joint. ⋯ The Intra-articular injection of morphine and sufentanil, reduce both the post arthroscopic knee procedures pain, and the need for supplementary analgesics. However, sufentanil, 5 microg is more effective than morphine.

Randomized Controlled Trial Clinical TrialPreemptive ketamine during general anesthesia for postoperative analgesia in patients undergoing laparoscopic cholecystectomy.
Preemptive analgesia is currently in use in the management of postoperative pain and no more under search. The administration of ketamine as intraoperative analgesic agent is well-known since a long time; the analgesic properties of this drug are related to its actions as a non-competitive N-methyl-D-aspartate receptors antagonist; these receptors present an excitatory function on pain transmission and this binding seems to prevent or reverse the central sensitisation of every kind of pain, including postoperative pain. In literature, the use of this anesthetic for the preemptive analgesia in the management of postoperative pain is controversial; for this reason the aim of our study was the clinical evaluation of preemptive perioperative analgesia with low-doses ketamine. ⋯ Our study suggests that preemptive low-doses ketamine is able to produce an adequate postoperative analgesia and increases the analgesic effect of tramadol; furthermore, ketamine adverse effects could be reduced by intraoperative administration of benzodiazepines and/or antiemetic drugs, or by the association of ketamine and a peripheral analgesic (ketorolac).

Comparative StudyDelayed epidural catheter removal: the impact of postoperative coagulopathy.
A retrospective analysis of 413 patients who received postoperative epidural analgesia under a standardized protocol found that 84 (20%) had a duration of epidural catheterization of greater than four days. The most common reasons were significant pain (n=64, 15%) and coagulopathy (n=26, 6%). Risk factor analysis for coagulopathy showed an odds ratio of 10.1 (95% confidence interval 4.2-24.5) for prolonged epidural catheterization among patients undergoing hepatectomy. ⋯ The signs soon resolved in all except two, one of whom had neuropathy related to intraoperative positioning and the other preoperative weakness. Accidental epidural catheter dislodgement occurred in 29 patients (7%) and is potentially hazardous if coagulopathy is unresolved. The risk-benefit ratio and factors complicating catheter removal, especially coagulopathy, should be considered when deciding whether to use epidural techniques.
