Randomized Controlled Trial Comparative Study Clinical Trial
Analgesia following extradural and i.m. pethidine in post-caesarean section patients.
The onset, quality and duration of analgesia following extradural pethidine 50 mg and i.m. pethidine 100 mg was assessed in 30 postoperative patients who had undergone Caesarean section under extradural anaesthesia. Saline and pethidine were given in a randomized, double-blind fashion using simultaneous extradural and i.m. injections. Extradural pethidine provided superior analgesia, of quicker onset but similar duration, and both treatments were associated with a low incidence of side effects.

[Critical aspects of an outside evaluation of postoperative pain in infants. A placebo-controlled double-blind study of the question of the reliability and validity of the measurement system].
Postoperative analgesia in infants and young children is a topic of growing interest in pediatric anesthesia. Two systems measuring postoperative pain in this group of patients have been offered recently: CHEOPS (Childrens Hospital of Eastern Ontario Pain Scale) by McGrath et al. and OPS (Objective Pain Scale) by Hannallah et al. and Broadman et al. [3, 7, 8]. Both systems are economical and not reactive, but their validity is not satisfying. ⋯ The design of the study was accepted by the ethic committee with the provision that neither a sedative nor an analgesic drug should be withheld from any child if indicated. Therefore, all children who seemed to feel discomfort according to the subjective impression of the anesthetist received midazolam intraveneously to a maximal dose of 2 mg. All the behavioral data were included in a factor analysis (principal components)...

Opioids are given for acute intra- and postope-rative pain relief or for chronic cancer pain. In the literature there are only rare and contradictory reports on the oral administration of opioids for chronic non-malignant pain. However, there is no reason to withhold strong analgesics for patients with severe pain. ⋯ Side effects are controlled by additional medication. The principle of opioid administration is prophylaxis of pain -therefore, they should be given "by the clock". Opioids are not only indicated in malignant illness, but also according to severity of pain and by the failure of other measures to control pain.

[Continuous infusion of epidural morphine to relieve postoperative pain. Protocol and results].
We have evaluated the efficaciousness and side effects of continuous administration of morphine by lumbar epidural route for relieving postoperative pain in major surgery of the abdomen and orthopedic surgery. Lumbar epidural catheters were placed to 25 patients (mean age, 52 years) before induction of general anesthesia. All patients received a 4 mg bolus dose of morphine sulfate 1 hour before finalization of general anesthesia and subsequently they were placed on a continuous infusion of morphine sulfate at 0.3-1 mg/h. ⋯ Duration of continuous analgesia varied from 3 to 5 days. No patient presented respiratory depression; four presented nausea and eight had urinary retention. We believe that continuous epidural infusion of morphine is efficacious and safe for the treatment of acute postoperative pain in patients undergoing abdomen major surgery and orthopedic surgery.

Randomized Controlled Trial Comparative Study Clinical Trial
Clonidine-induced analgesia in postoperative patients: epidural versus intramuscular administration.
To compare the analgesic efficacy and plasma concentration of intramuscular (IM) versus epidural (EP) clonidine, 20 patients recovering from orthopedic or perineal surgery were randomly divided into two groups of ten. Clonidine (2 micrograms/kg) was administered epidurally in group 1 and intramuscularly in group 2. Analgesia was assessed using a visual analog scale (VAS) over a period of 6 h following clonidine administration. ⋯ Hypotension, bradycardia, and drowsiness occurred with both methods of administration. None of these effects required treatment. Thus, in postoperative patients clonidine produces similar analgesia and side effects after parenteral or EP administration.
