Patient controlled epidural analgesia during labour: choice of solution.
Epidural characteristics, when using different solutions for patient controlled epidural analgesia (PCEA), were compared in a randomised, blinded study in labour. Women in group 1 (n=23) self-administered 0.25% plain bupivacaine, in group 2 (n=23) 0.125% plain bupivacaine plus fentanyl 3 microg/ml and in group 3 (n=20) 0.0625% bupivacaine with adrenaline 1:250,000 plus fentanyl 3 microg/ml. ⋯ The rate of bupivacaine utilisation was significantly higher in group 1 compared to groups 2 and 3 and lower in group 3 compared to 1 and 2 (median+interquartile range: 16+11-21 vs 9+6-11 vs 4+3-8 mg/hr, P<0.0002). Although all solutions provided effective pain relief for PCEA during labour, the use of a low-dose bupivacaine-fentanyl combination offers clinical advantages and further evaluation of such solutions is warranted.

Review[Is there an advantage to using opioid combinations by the peridural route?].
Epidural opioids provide a potent analgesia not devoided of side effects. In addition, epidural administration of lipid soluble opioids has no clear advantage over the IV route. Combination of epidural opioids with other analgesics may strengthen analgesia and may decrease the incidence of side effects because of a reduction in the amount of opioid administered. ⋯ Clonidine, which is a selective alpha-2-adrenergic agonist has been demonstrated to improve and to prolong analgesia produced by opioids in postoperative patients. Clonidine administration induces side effects, like sedation, bradycardia and hypotension, but allows to highly reduce the opioid dose. None of the combined techniques of analgesia implies that monitoring of the side effects of opioids has to be reduced.

Comparative Study
A comparison of patient-controlled analgesia and continuous lumbar plexus block after anterior cruciate ligament reconstruction.
Anterior cruciate ligament (ACL) reconstruction is often a painful operation. Fifty-eight patients who underwent ACL reconstruction using patellar tendon autograft received either a lumbar plexus block (LPB) or patient-controlled analgesia (PCA) for pain relief during the first 24 h after surgery. ⋯ The common narcotic analgesic side effects of nausea, pruritus, sedation, and urinary retention were significantly less in the LPB group. The LPB is a safe and effective alternative analgesia after ACL reconstruction.
