Randomized Controlled Trial Comparative Study Clinical TrialA comparison of postoperative pain relief techniques in orchidopexy.
Fifty consecutive patients admitted to the Western General Hospital for orchidopexy, were randomly allocated to receive either a caudal bupivacaine block or peroperative wound instillation with bupivacaine, to provide postoperative analgesia. Bupivacaine wound instillation reduced the total operating time, gave more efficient postoperative pain relief in hospital and proved both inexpensive and simple in its application.

Recent evidence suggests that postoperative pain is poorly controlled and it is reported that nearly 75% of hospitalized patients failed to receive adequate pain relief. It was hypothesized that there was no difference between expected and experienced pain and that pain scores on the first postoperative day would be 'low'. Factors affecting the management of pain were identified using a patient questionnaire. ⋯ The nurse did not play a key role in the preoperative information given to the patient. Patients experienced 'worsened' pain in the morning and evening. Nurses questioning patients about their pain often failed to identify those in pain.

Recent advances in neurophysiology and neurochemical management of pain has lead to a new concept in pain relief in the post-operative period. After a review of the pain perception mechanism and of the effects of antinociceptive drugs, the authors present simplified protocols for the management of post operative pain in pediatric surgery.

Postoperative pain relief with epidural morphine and buprenorphine was studied in 33 patients following hepatectomy. Morphine 2mg or buprenorphine 0.06mg in 10ml of normal saline was administered through an epidural catheter inserted at the Th10-11 or L3-4 interspace. ⋯ Buprenorphine injected at the thoracic level produced good and long-lasting (22.6 +/- 9.9 hours) pain relief, although buprenorphine injected at the lumbar level produced incomplete analgesia. The epidural administration of morphine 2mg at L3-4 or buprenorphine 0.06mg at Th10-11 may be recommended for postoperative analgesia following hepatectomy.

Circumcision in children is followed by severe pain. This study analysed retrospectively anesthetic techniques of 110 children from 17 months to 14 years old who had undergone ambulatory of 24 h stay circumcision. There were two groups of patients: one being operated on under locoregional techniques combined with general anesthesia (53.6%), the other one under general anesthesia alone (46.4%). ⋯ In the first group, dorsal nerves block of the penis (DNBP) was performed on 47 children (79.8% of the locoregional techniques), caudal block on 10 patients and ring block on 2 patients. Regional techniques offered a satisfactory, safe and reliably effective post circumcision analgesia. DNBP should be used systematically in order to shorten duration of day circumcision stay.
