Abstract
The aim of this study is to evaluate the efficacy of the pericapsular nerve group block and local infiltration analgesia (LIA) combination as the only anesthesia technique for the total hip arthroplasty (THA). We considered the anesthetic plan, postoperative analgesia, hospital length of stay, functional recovery, bleeding, complications and the adverse events. We reported 10 ASA I–II patients admitted for elective primary THA, receiving LIA during (5) and at the end of surgery (5). For the PENG block we used a single injection of 40 ml levobupivacaine 0.25% and dexamethasone 4 mg. For LIA, a mixture of 0.25% levobupivacaine, ketorolac, epinephrine, and morphine was injected into periarticular tissues. The pain intensity was evaluated with a numeric rating scale. All patients were fully satisfied and improvement in pain relief, symptoms, and functional activity was remarkable. Intraoperative blood losses ranged 100–600 ml. No intraoperative complications or signs of toxicity occurred. The median duration of surgery was 59.5 ± 4.5 min and the hospital stay ranged between 2 and 3 days. PENG block and LIA could be hypothesized as an effective and safety anesthesia technique for the THA surgery, facilitating hip functional recovery and limit intraoperative blood losses and adverse events.
