Comparative Study[Epidural analgesia with clofelin in treating a pain syndrome].
The article presents a clinical experience with using epidural analgesia with Clofelin in 20 patients to arrest the pain syndrome developed at the postoperative period and resulting from atherosclerotic lesions of the lower extremity vessels. Control of the adequacy of anesthesia was made by registration of the H-reflex value. The investigations have shown that epidural analgesia with Clofelin is an effective measure to arrest the pain syndrome.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of epidural and patient-controlled intravenous morphine following joint replacement surgery.
The authors conducted a randomized, prospective study comparing epidural morphine with patient-controlled intravenous (iv) morphine in 30 patients recovering from total hip or total knee arthroplasty. Six, 18, and 24 hr postoperatively, patients used a 10 cm visual-analogue scale to indicate both their current degree of discomfort and the maximum discomfort they had experienced since the previous evaluation. Pain at the time of evaluation did not differ between patients receiving epidural (2.6 +/- 0.4 cm, mean +/- SEM) and patient-controlled iv morphine (3.4 +/- 0.3 cm). ⋯ Patients receiving epidural morphine were more likely to require treatment for pruritus (4 of 15) than patients who received patient-controlled iv morphine (none of 15, P less than 0.05). Minimum respiratory rates were lower in patients receiving epidural morphine (15.0 +/- 0.3) than in those receiving patient-controlled analgesia (16.5 +/- 0.4, P less than 0.05), but no patients required treatment for respiratory depression. The authors conclude that epidural morphine may provide more consistent analgesia following joint replacement surgery than patient-controlled morphine; however, there is a higher incidence of side-effects with the epidural technique.

Randomized Controlled Trial Comparative Study Clinical Trial
Epidural bupivacaine dilution for labour. A comparison of three concentrations infused with a fixed dose of fentanyl.
We have compared the effects of three epidural infusions in a randomised, double-blind study of 56 primigravid mothers in labour. An initial dose of bupivacaine 0.5% 8 ml was followed by infusion of either bupivacaine 0.125%, 0.062% or 0.031%. ⋯ Women receiving the most dilute solution had significantly less analgesia (p less than 0.001) for the first 4 hours of the study, but pain scores were then similar for the three groups. No obvious benefit was gained by using very dilute bupivacaine.

[Continuous epidural treatment of cancer pain using a portable infusion pump].
Treatment of cancer pain with opioids through an epidural catheter, with a portable infuser has been recorded in 20 patients retrospective. In general there was a good acceptance of the treatment, which often could liberate the patients from close contacts to the pain clinic. ⋯ One patient had systemic adverse effects because of a very high daily opioid dose. The Pharmacia Deltec infuser employed has proven very secure and easy to handle.

Does the anesthetic technique influence the postoperative analgesic requirement?
In order to determine the effect of two standard general anesthetic techniques on the postoperative analgesic requirement, 53 adults undergoing elective intra-abdominal surgery were randomly assigned to one of two anesthetic treatment groups according to an open parallel protocol design. One of the groups received an opioid-based anesthetic; the other group was administered an inhaled anesthetic. The postoperative analgesic requirement was quantified using a Baxter PCA device. ⋯ During the first 8 hours after discharge from the recovery room there was a trend toward higher PCA morphine usage in the inhaled anesthetic group (25.6 +/- 15 mg vs. 18.6 +/- 13 mg); however, this difference was not statistically significant (p = 0.08). From 8 to 40 hours after surgery, the morphine usage was nonsignificantly higher in the opioid group (64 +/- 30 mg vs. 56 +/- 38 mg, p = 0.43). In conclusion, the general anesthetic technique used during an elective operation appeared to have little if any effect on the postoperative analgesic requirement after discharge from the recovery room.
