Randomized Controlled Trial Clinical Trial[Postoperative pain therapy following total endoprosthetic surgery on the hip using a continuous 3-in-1 blockade].
40 patients who had undergone total hip replacement were included in a randomised prospective study. Postoperative pain management was performed with a continuous 3-in-1 block combined with demand-adapted intravenous meperidine titration (3-in-1 catheter group; n = 20) or by demand-adapted intravenous meperidine titration alone (control group; n = 20). The 3-in-1 catheter was placed before the start of anesthesia, and the patients received 30 ml 0.5% bupivacaine via this catheter. ⋯ Placement of the 3-in-1 catheters was without complications. For the management of postoperative pain following total hip replacement a continuous 3-in-1 block alone was often insufficient but postoperative meperidine requirements were significantly reduced (p < 0.05). Toxic bupivacaine plasma concentrations were not measured.
