Randomized Controlled Trial Comparative Study Clinical TrialInhibition of epidural morphine-induced pruritus by intravenous droperidol. The effect of increasing the doses of morphine and of droperidol.
Because the mechanism of inhibition of epidural morphine-induced pruritus by droperidol is not clear, this study was undertaken to determine the effects of larger doses of droperidol or morphine, or both. ⋯ Pruritus caused by epidural use of 2 or 4 mg of morphine is inhibited by the intravenous use of 2.5 mg droperidol but not by a larger dose.

Randomized Controlled Trial Comparative Study Clinical Trial
Post-operative pain relief in children following extraction of carious deciduous teeth under general anaesthesia: a comparison of nalbuphine and diclofenac.
In a randomized double-blind study 60 children, undergoing the extraction of carious deciduous teeth under day-case general anaesthesia, were assigned to receive either intravenous nalbuphine hydrochloride 0.3 mg kg-1 (n = 21), one or more diclofenac suppositories 12.5 mg to a dose of 1-2 mg kg-1 (n = 19), or no analgesia (n = 20). The duration of anaesthesia was longer in the diclofenac group (9.6 min, SD 3.5) compared with control (7.2 min, SD 2.6) and nalbuphine (6.9 min, SD 3.0) groups respectively (P < 0.05). There were no statistically significant differences in post-operative pain scores during the 45 min post-operative period studied between the three groups using an objective pain score. We conclude that using this methodology we were unable to demonstrate any statistically significant differences between the analgesic effects of either intravenous (i.v.) nalbuphine or diclofenac suppositories compared with control.

Randomized Controlled Trial Clinical TrialRoutine use of fentanyl infusions for pain and stress reduction in infants with respiratory distress syndrome.
To determine whether fentanyl infusions given to premature infants with respiratory distress syndrome reduce stress and improve long- and short-term outcome. ⋯ Although there was a reduction in stress markers in the infants receiving fentanyl, we were unable to demonstrate an improvement in catabolic state or long-term outcome. In addition, the infants receiving fentanyl required higher ventilatory support in the early phase of respiratory distress syndrome than did those receiving placebo.

Randomized Controlled Trial Clinical Trial
Analgesic efficacy of controlled-release oxycodone in postoperative pain.
The efficacy and safety of graded doses (10, 20, and 30 mg) of controlled-release (CR) oxycodone was compared with that of immediate-release (IR) oxycodone (15 mg), immediate-release oxycodone 10 mg in combination with acetaminophen 650 mg (APAP), and placebo in a single-dose, double-blind, randomized, parallel-group study. The participants, 182 inpatients experiencing moderate to severe pain after abdominal or gynecologic surgery, provided hourly ratings of pain intensity and relief for 12 hours after administration. All active treatments were significantly superior to placebo for many hourly measurements and for the sum of pain intensity differences (SPID) and total pain relief (TOTPAR). ⋯ Duration of pain relief showed that the 10-, 20-, and 30-mg doses of CR oxycodone had durations of action of 10 to 12 hours compared with IR oxycodone and oxycodone plus APAP (both approximately 7 hours). Typical adverse events, particularly somnolence, occurred in all active treatment groups. Treatment with CR oxycodone was safe and effective in this study, and its characteristics will be beneficial in the treatment of pain.

Randomized Controlled Trial Clinical TrialEffect of epidural buprenorphine and clonidine on vesical functions in women.
Buprenorphine (4 micrograms/kg body weight) and clonidine (3 micrograms/kg body weight) were administered epidurally to investigate their effect on vesical function in 20 American Society of Anaesthesiologists Classification I (ASA I) adult females. Cystometry was performed before and 30 minutes following epidural administration of drugs. ⋯ Epidural administration of clonidine did not produce any significant change in the above urodynamic parameters. None of the patients in both groups developed retention of urine.
