Randomized Controlled Trial Clinical Trial
Is the effect of inguinal field block with 0.5% bupivacaine on postoperative pain after hernia repair enhanced by addition of ketorolac or S(+) ketamine?
The aim of the study was to assess whether coadministration of S(+) ketamine or ketorolac would enhance or prolong local analgesic effect of bupivacaine after inguinal hernia repair. ⋯ The addition of S(+)-ketamine or ketorolac only minimally improves the analgesic effect of bupivacaine. This may be related to the tension-free hernia repair technique associated with low postoperative pain.

Randomized Controlled Trial Clinical TrialParasternal block and local anesthetic infiltration with levobupivacaine after cardiac surgery with desflurane: the effect on postoperative pain, pulmonary function, and tracheal extubation times.
Early tracheal extubation has become common after cardiac surgery. Anesthetic techniques designed to achieve this goal can make immediate postoperative analgesia challenging. We conducted this randomized, placebo-controlled, double-blind study to investigate the effect of a parasternal block on postoperative analgesia, respiratory function, and extubation times. ⋯ Four of nine in the placebo group needed rescue pain medication, versus none of eight in the levobupivacaine group (P=0.08). Peak serum levobupivacaine concentrations were below potentially toxic levels in all patients (0.64 +/- 0.43 microg/mL; range, 0.24-1.64 microg/mL). Parasternal block and local anesthetic infiltration of the sternotomy wound and mediastinal tube sites with levobupivacaine can be a useful analgesic adjunct for patients who are expected to undergo early tracheal extubation after cardiac surgery.

Editor's note: The anti-inflammatory drug rofecoxib (Vioxx) was withdrawn from the market at the end of September 2004 after it was shown that long-term use (greater than 18 months) could increase the risk of heart attack and stroke. So far, other similar anti-inflammatory drugs are unaffected. Further information is available at www.vioxx.com. Rofecoxib is a selective cyclooxygenase-2 (COX-2) inhibitor that was licensed in the UK and the US for acute pain treatment and is associated with fewer gastrointestinal adverse events than conventional NSAIDs. Rofecoxib is believed to be at least as effective as conventional non-steroidal anti-inflammatory drugs (NSAIDs) for postoperative pain. ⋯ Rofecoxib 50 mg (a dose 2 to 4 times the standard daily dose for chronic pain) is an effective single dose oral analgesic for acute postoperative pain.

Randomized Controlled TrialAnalgesic efficacy of tramadol by route of administration in a clinical model of pain.
The objective of this study was to evaluate the analgesic efficacy produced by tramadol given by two different routes of administration in patients experiencing pain after removal of an impacted mandibular third molar under local anesthesia. A double-blind, randomized, placebo-controlled clinical trial was conducted. Patients were assigned into four groups of treatment, twelve subjects per group: Group A, tramadol 50 mg IM one hr before surgery; group B, tramadol 50 mg into the surgical site; group C, tramadol by both routes of administration, 50 mg IM one hr before surgery plus 50 mg into the surgical site; and group D, control. ⋯ However, only in the route combination group was a significant reduction in the requirement of acetaminophen observed. Nine patients requiring additional medication were treated with ketorolac 30 mg injected intramuscularly; 2 in the systemic group, 2 in the local group, 4 in the control group and only 1 in the combination group. Adverse events were minimal and similar in all groups.

Randomized Controlled Trial Comparative Study Clinical Trial
Xenon does not reduce opioid requirement for orthopedic surgery.
Is to test the hypothesis that 70% xenon has a relevant opioid sparing effect compared to a minimum alveolar concentration (MAC)-equivalent combination of N(2)O and desflurane. ⋯ Xenon compared to a MAC-equivalent combination of N(2)O and desflurane does not substantially reduce opioid requirement for orthopedic surgery. A small but clinically irrelevant difference cannot be excluded, however.
