| Abstract [eng] |
Choice of optimal postoperative analgesia technique after anterior crutiate ligament repair remains challenging. Aiming to evaluate and compare the efficacy of intra-articular injection of morphine and neostigmine our prospective randomized clinical study compared pain intensity, consumption of adjunct analgesics and patient satisfaction during 48 postoperative hours in patients who, in addition to spinal block, received a single-shot femoral nerve block followed by the end-of-surgery intra-articular injection of morphine, neostigmine or placebo. Additionally, the former two were compared with continuous femoral nerve block with postoperative patient controlled analgesia infusion pump containing 0.1 % bupivacaine preset in 2 different regimens: with or without basal infusion. Our results show that there was only a single difference among intra-articular groups found on the 2nd postoperative day: a significantly better pain control at motion in neostigmine group than in the placebo group. There was no additive analgesic effect of i/a morphine. Also, we observed a significantly better pain control and patient satisfaction in continuous femoral perineural block PCA groups during the whole trial. There was a significant prevalence of the PCA analgesia regimen which implies the preset basal rate of 0.1% bupivacaine: a 5 ml bolus with a lockout period 30 min and basal infusion 5 ml/h. |
