Randomized Controlled Trial Comparative Study Clinical Trial
Ketorolac potentiates morphine in postoperative patient-controlled analgesia.
The authors conducted a prospective randomised double-blind comparison of patient-controlled analgesia (PCA), with a combination of morphine and ketorolac versus morphine alone and ketorolac alone in the management of postoperative pain after orthopaedic surgery. Forty-two patients were randomly assigned to three groups. Group 1 was given 1 mg/ml morphine, group 2 was given 3 mg/ml ketorolac and group 3 half-doses of each. ⋯ The incidence of urinary retention was highest in the group given morphine alone. The combination of half-doses of morphine and ketorolac is more effective in controlling postoperative pain than either drug alone. This combination also reduces analgesic consumption and morphine-related adverse events.

Psychological approaches during conscious sedation. Hypnosis versus stress reducing strategies: a prospective randomized study.
Stress reducing strategies are useful in patients undergoing surgery. Hypnosis is also known to alleviate acute and chronic pain. We therefore compared the effectiveness of these two psychological approaches for reducing perioperative discomfort during conscious sedation for plastic surgery. ⋯ Vital signs were significantly more stable in the HYP group. Patient satisfaction score was significantly higher in the HYP group (P < 0.004). This study suggests that hypnosis provides better perioperative pain and anxiety relief, allows for significant reductions in alfentanil and midazolam requirements, and improves patient satisfaction and surgical conditions as compared with conventional stress reducing strategies support in patients receiving conscious sedation for plastic surgery.

Randomized Controlled Trial Clinical Trial
Infiltration of morphine into an abnormal wound; effects on pain relief and endocrine/immune response.
We wanted to evaluate pain relief and endocrine/immune response after local administration of morphine into an abdominal wound. In a randomised double blind design 29 patients undergoing hysterectomy received two blinded injections of morphine and saline. Before surgery the patients in the control group (n = 15) got 10 mg of subcutaneous morphine into an arm and at skin incision 30 ml of saline was infiltrated directly into the wound. ⋯ High doses of i.v. morphine reduced cortisol and IL-6 levels in the early hours after surgery. The injection of morphine into the wound did not improve pain relief or reduce the consumption of i.v. morphine after surgery. The endocrine stress response to trauma was modified by preoperative administration of morphine.

Randomized Controlled Trial Clinical Trial
Lamotrigine (lamictal) in refractory trigeminal neuralgia: results from a double-blind placebo controlled crossover trial.
Lamotrigine is a chemically novel antiepileptic drug which has not been adequately assessed for its antineuralgic properties. It was used in a double-blind placebo controlled crossover trial in 14 patients with refractory trigeminal neuralgia. Patients continued to take a steady dose of carbamazepine or phenytoin throughout the trial over a 31-day period. ⋯ The adverse reactions with both lamotrigine and placebo were predominantly dose-dependent effects on the central nervous system. A 14th patient withdrew from the study due to severe pain during the placebo arm of the trial. It would appear that lamotrigine has antineuralgic properties.

Randomized Controlled Trial Comparative Study Clinical Trial
The efficacy of radiofrequency lesioning of the cervical spinal dorsal root ganglion in a double blinded randomized study: no difference between 40 degrees C and 67 degrees C treatments.
The efficacy of radiofrequency lesion treatment of the cervical dorsal root ganglion (RF-DRG) in cervicobrachialgia was investigated in 61 patients by a randomized prospective double blinded study. Before lesion treatment the putative pain provoking spinal root was identified by diagnostic blocks with a local anesthetic agent. One group of patients (n = 32, group I) was treated with a radiofrequency lesion of 67 degrees C and in a control group (n = 29, group II) a temperature of 40 degrees C was applied. ⋯ A VAS reduction of 2 or more occurred in group I in 15/31 (47%) and in group II in 15/29 (51%) of patients. This study suggests that treatment with 40 degrees C radiofrequency application of the dorsal root ganglion is equally effective as treatment at 67 degrees C. Further appraisal of this treatment is required.
