Review Clinical Trial
Assessment and management of postoperative pain in children.
This paper focuses on the knowledge base about the assessment and management of postoperative pain in children. The first section deals with the nature and characteristics of postoperative pain. A description of current pain management practices with children, focusing on analgesic administration, is derived from available research literature. ⋯ Recent advances in pain assessment and measurement in all age groups, particularly with verbal children and the new self-report measures, are discussed. The latest developments in pharmacological and nonpharmacological techniques for the relief of children's postoperative pain are also described. Finally, the paper concludes with a few suggestions for pediatricians relative to their role in assisting in the search for better assessment and management techniques in the care of postoperative children.

Randomized Controlled Trial Comparative Study Clinical Trial[A combination of sufentanil and 0.25% bupivacaine administered epidurally for obstetrical analgesia. Comparison with fentanyl and placebo].
The study reported was designed to determine whether 15 micrograms sufentanil would provide analgesia comparable in duration and quality with that given by 75 micrograms fentanyl, when associated with plain 0.25% bupivacaine for extradural analgesia for labour. Patients (n = 124) in labour and at full term were randomly divided into 3 groups. Group 1 (n = 41) were given 12 ml of 0.25% plain bupivacaine with saline, group 2 (n = 41) 12 ml of 0.25% plain bupivacaine with 75 micrograms fentanyl and group 3 (n = 42) 12 ml of 0.25% plain bupivacaine with 15 micrograms sufentanil. 11 cases were excluded from the study (8 Caesarean sections, 3 technical failures). ⋯ The only side-effect seen with sufentanil and fentanyl was pruritus (group 2: 21.9%, p less than 0.05; group 3: 21.4%, p less than 0.05; group 1: 2.4%). These results showed that 15 micrograms sufentanil could replace 75 micrograms fentanyl for extradural pain relief of labour with plain 0.25% bupivacaine. However, the use of opioids with local anaesthetics would seem to be of interest only if labour is likely to be prolonged.

The treatment of pain in acute myocardial infarction varies with local practice. Narcotic analgesics are still the usual treatment in many hospitals. Knowledge of optimal doses, duration of pain relief, and time between drug administration and pain relief is inadequate. ⋯ Large randomised studies consistently show that beta blockade, initially given intravenously and then orally, relieves pain and reduces the need for analgesics. Studies also indicate that early administration of streptokinase and glyceryl trinitrate relieves pain. There is evidence that drugs that limit ischaemic damage also relieve pain.

The discovery of opiate receptors and naturally occurring opiate-like substances in the central nervous system started a new era in pain control. Epidural and spinal opiates have been increasingly used since 1979. However, applying these analgesic techniques in obstetrics has been criticized because of possible side-effects on the mother and foetus. ⋯ The choice of a lipid-soluble opiate like fentanyl is safe. However, when considering new drugs, great care must be taken to avoid unforeseen problems. A good knowledge of the problem and a cautious approach combined with careful monitoring of the respiratory rate and adequacy of ventilation are the keys to the safe use of spinal and epidural opiates.

Comparative Study
A study of pain management: patient controlled analgesia versus intramuscular analgesia.
A clinical study examining the efficacy of Patient Controlled Analgesia compared with Intramuscular Analgesia was conducted. Patient Controlled Analgesia (PCA) Therapy was used in a select group of patients after major abdominal surgery. Specific parameters monitored were: total amount of analgesia required, incidence of pulmonary complications, assessment of pain level and sedation, patient activity, nursing time required for administration, safety, cost-effectiveness of both modes of analgesia and length of hospital stay. ⋯ The patient on PCA therapy is able to titrate his analgesic medication very effectively and maintain a state of analgesia without sedation. He is more responsive and able to participate in the early postoperative rehabilitation phase. The transition to oral medication usually was accomplished at 48 hours postoperative.
