Randomized Controlled Trial Comparative Study Clinical TrialComparison of intravenous nalbuphine infusion versus naloxone in the prevention of epidural morphine-related side effects.
Epidural morphine is accepted as an efficient means of postoperative pain management. However, development of side effects such as nausea and vomiting and pruritus has been reported. This study compared the efficacy of intravenous infusions of nalbuphine or naloxone in the prevention of epidural morphine-related side effects. ⋯ We found that coadministration of either nalbuphine or naloxone with epidural morphine reduces the incidence of morphine-related side effects. However, unlike naloxone, nalbuphine did not attenuate the analgesic effect of epidural morphine.

Randomized Controlled Trial Meta Analysis Comparative Study Clinical TrialRegional anesthesia does not significantly change surgical time versus general anesthesia--a meta-analysis of randomized studies.
The major determinant of variable operating room costs is surgical time. A number of factors contribute to surgical time. This study was designed to determine whether regional anesthesia decreases surgical time when compared with general anesthesia over several surgical procedures. ⋯ Overall, the use of regional anesthesia does not significantly decrease surgical time.

Randomized Controlled Trial Comparative Study Clinical TrialThe paravertebral nerve root block for inguinal herniorrhaphy--a comparison with the field block approach.
Our objective was to evaluate the efficacy of the paravertebral block for inguinal herniorrhaphy by comparison with the well-established field block. ⋯ The paravertebral nerve root block proved to be superior to the field block, to be devoid of side effects, and was acceptable to the patients.

Randomized Controlled Trial Clinical TrialThe safety and efficacy of intrabursal oxycodone and bupivacaine in analgesia after shoulder surgery.
Peripherally administered opioids, e.g., intra-articular morphine, exert their analgesic action on local opioid receptors. The present study investigated the safety and efficacy of intrabursal oxycodone and bupivacaine in comparison with bupivacaine infiltration and interscalene brachial plexus block in conjunction with shoulder surgery. ⋯ According to the present study, intrabursal oxycodone and bupivacaine offer an acceptable and efficient method for postoperative analgesia after shoulder surgery.

Randomized Controlled Trial Clinical TrialAnalgesic effect of interscalene block using low-dose bupivacaine for outpatient arthroscopic shoulder surgery.
Although interscalene brachial plexus block (ISBPB) is often used to provide anesthesia for arthroscopic shoulder surgery, its selective analgesic effect, provided by low-dose local anesthetic, has not been studied. We hypothesized that ISBPB using a low volume and low concentration of bupivacaine can provide effective postoperative analgesia for shoulder surgery without producing significant sensory or motor block elsewhere. ⋯ Interscalene brachial plexus block with low-dose bupivacaine is a useful and selective analgesic technique for outpatient shoulder arthroscopic surgery.
