Randomized Controlled Trial Comparative StudyA comparison of mepivacaine versus lidocaine for episcleral (sub-tenon's) block for cataract surgery in an ambulatory setting.
For eye surgery, motor block is still often requested by the surgeon. For cataract surgery, rapid block resolution allows eyelids to move and allows eye-patch removal. Therefore, short-duration block is useful in early rehabilitation for ambulatory surgery. Lidocaine is classically assumed to have shorter duration than mepivacaine. Therefore, lidocaine alone might be considered as an alternative to mepivacaine. ⋯ We found no argument to favor lidocaine over mepivacaine in episcleral (sub-Tenon's) eye block, especially in terms of motor-block duration.

Randomized Controlled Trial Comparative StudyA comparison of stimulation patterns in axillary block: part 2.
Radial plus musculocutaneous nerve stimulation may have a predominant role in the success of an axillary block, producing more extensive anesthesia of the upper limb than median plus musculocutaneous nerve stimulation. However, no comparison has been made with ulnar plus musculocutaneous nerve stimulation. We compared the extent of both sensory and motor block after ulnar plus musculocutaneous nerve stimulation or radial plus musculocutaneous nerve stimulation. ⋯ Radial plus musculocutaneous nerve stimulation produced more extensive anesthesia of the upper limb than did ulnar plus musculocutaneous nerve stimulation. However, there is not an optimal combination of 2 responses in axillary brachial plexus block.

Randomized Controlled TrialMagnesium added to prilocaine prolongs the duration of axillary plexus block.
The aim of this study was to evaluate the effect of the addition of magnesium to prilocaine on the duration of sensory and motor-nerve block. ⋯ The admixture of magnesium to prilocaine for axillary brachial plexus block provided a pronounced prolongation of sensory and motor block without side effects.

Randomized Controlled Trial Comparative StudyEvaluation of the effect of perioperative rofecoxib treatment on pain control and clinical outcomes in patients recovering from gynecologic abdominal surgery: a randomized, double-blind, placebo-controlled clinical study.
In this randomized, placebo-controlled, double-blind study, the efficacy and safety of rofecoxib 50 mg was evaluated in patients undergoing major abdominal gynecologic surgery. ⋯ Compared with placebo, perioperative administration of rofecoxib 50 mg provided significant opioid sparing, significantly better pain control, improved clinical outcomes, and was well tolerated.

Randomized Controlled Trial Comparative StudyEfficacy of low-dose intrathecal morphine for postoperative analgesia after abdominal aortic surgery: a double-blind randomized study.
Several studies suggest that intrathecal morphine (ITM) improves analgesia after aortic surgery. We tested the hypothesis that in combination with multimodal postoperative pain management, low-dose ITM associated with general anesthesia would decrease postoperative analgesic requirements in patients undergoing abdominal aortic surgery. ⋯ In patients undergoing abdominal aortic surgery, intrathecal morphine (0.2 mg) improves postoperative analgesia and decreases the need in intraoperative and postoperative analgesics. Further studies are indicated to evaluate the role of ITM in postoperative recovery.
