Randomized Controlled Trial Clinical Trial
Lignocaine plus morphine in bolus patient-controlled intravenous analgesia lacks post-operative morphine-sparing effect.
Lignocaine has been used successfully to treat burn pain and neuropathic pain. We have conducted a randomized, double-blind trial to assess the morphine-sparing effect of intravenous lignocaine in patients with acute pain. After major abdominal surgery, patients were treated with post-operative patient-controlled intravenous analgesia in two groups: group M (n = 25, morphine 0.2 mg mL-1) and group ML (n = 25, morphine 0.2 mg mL-1 plus lignocaine 3.2 mg mL-1). ⋯ However, the sedation scores in group ML patients during the first post-operative day were significantly greater than those in group M. The incidence of lignocaine-related lightheadedness and dry mouth was also significantly greater in group ML than in group M. It was concluded that the addition of lignocaine 3.2 mg mL-1 to morphine 0.2 mg mL-1 given via patient-controlled analgesia system does not provide a post-operative morphine-sparing analgesic effect.

Immune alterations associated with epidural analgesia for labor and delivery.
Epidural analgesia is frequently used for the laboring woman and commonly regarded as safe. The association of epidural analgesia with fever, in the absence of infection, in this population can result in unnecessary sepsis workups in both neonates and mothers. Studies in other populations of patients have found that epidural anesthesia may be associated with alterations in white blood cell count parameters. This study was designed to determine if epidural analgesia is associated with alterations in immune profile or immune function in healthy afebrile postpartum women. ⋯ Nurses can be confident that the white blood cell count and other phenotypic measures of leukocytes are not affected by epidural analgesia. Thus the epidural analgesic technique appears not to alter immune measures of infection in postpartum women. In evaluating fever in postpartum mothers and neonates, nurses should consider prior receipt of epidural analgesia and measures of immune profile. In addition to fever and white blood cell counts, other signs and symptoms of infection should also be evaluated in postpartum women when infection is suspected.

Randomized Controlled Trial Comparative Study Clinical TrialPostoperative analgesia in children using preemptive retrobulbar block and local anesthetic infiltration in strabismus surgery.
Postoperative pain management in pediatric strabismus patients is infrequently studied. Pediatric patients can be mobilized earlier if postoperative pain is minimized. In this study, two different regional anesthetic techniques, retrobulbar block and local infiltration, were compared with a "no block" control group for the postoperative management of pain in pediatric patients undergoing elective strabismus surgery. ⋯ Because there was no significant difference in terms of postoperative analgesia in the retrobulbar block or subconjunctival local anesthetic infiltration groups compared with the control group, we suggest that conventional methods of pain treatment are adequate for postoperative analgesia in strabismus surgery.

Randomized Controlled Trial Comparative Study Clinical Trial
Bupivacaine 0.125% produces motor block and weakness with fentanyl epidural analgesia in children.
Epidural infusions of fentanyl (2 micrograms.ml-1) alone or combined with bupivacaine 0.125% were compared for perioperative analgesia, motor block and other side-effects in children who underwent urological surgery. ⋯ Postoperative epidural fentanyl infusion provides equipotent analgesia to administration of a solution including both fentanyl and bupivacaine 0.125% and causes less lower limb weakness. No reduction in the fentanyl requirement resulted from the addition of bupivacaine 0.125%.
