Comparing Continuous Lumbar Plexus Block, Continuous Epidural Block And Continuous Lumbar Plexus Block With A Parasacral Sciatic Nerve Block On Post-Operative Analgesia After Hip Arthroplasty

Abstract

Study Objective: To compare post-operative analgesia obtained by continuous lumbar epidural block (CLEB) versus continuous lumbar plexus block (CLPB) versus CLPB associated with a single shot parasacral sciatic nerve block (CLEBS) after total hip arthroplasty (THA). Study design: Randomized clinical trial.Setting: Operating room, postoperative care unit, orthopedic surgical ward.Methods: 78 ASA I-III patients undergoing elective THA were randomly assigned to receive CLEB (n=24, 15-20 ml of 5 mg/ml ropivacaine, sufentanil 10 mg, clonidine 1 mg/ml), CLPB (n=22, 3mg/kg of 5 mg/ml of ropivacaine, max. 40 ml, clonidine 1 mg/ml, sufentanil 10 mg) or CLPBS (n=23, CLPB as described above; sciatic nerve: 20 ml of ropivacaine 5 mg/ml, clonidine 1 mg/ml). All patients received continuous infusion of 2 mg/ml of ropivacaine, 8 ml/h for 48 hours. Primary outcome was pain intensity assessment (VAS and VS). Secondary outcomes were postoperative total opioid consumption, hemodynamic stability, motor blockade, blood loss, intraoperative sufentanil and propofol consumption, patient satisfaction and complications.

Is Local Infiltration Analgesia Superior to Peripheral Nerve Blockade for Pain Management After THA: A Network Meta-analysis

“…3). In addition to the RCTs included in the two pairwise meta-analyses, Bayesian network meta-analysis included 10 more RCTs [3,12,14,19,32,45,48,53,55,61] comparing use of local infiltration analgesia or peripheral nerve blocks with epidural analgesia or intrathecal morphine. By introducing the additional indirect comparisons (epidural analgesia, intrathecal morphine) we increased the power and precision of the network meta-analysis (Appendix 1.…”
