LP018 The adductor canal (saphenous) block and the sacral ESP block in a case of total knee arthroplasty. A case report

<h3></h3> <b>Please confirm that an ethics committee approval has been applied for or granted:</b> Not relevant <h3>Background and Aims</h3> TKA is commonly used to treat severe osteoarthritis. Regional anesthesia was successfully added to post-surgery pain management after TKA, helping lower pain scores, reduce opioid use, and minimize side effects. For TKA, literature supports using the adductor canal block (ACB) as part of a pain relief plan, but this technique doesn’t cover the entire knee. So, an additional block is suggested to get complete pain relief. <h3>Methods</h3> In a multimodal approach to post-operative pain management in a patient who underwent TKA, adductor canal (saphenous nerve) block together with sacral erector spinae plane block were provided. Then, for the surgery, an opioid-free (general) anesthesia was provided through laryngeal mask and desflurane MAC 0,5-1. Ketorolac 30 mg + paracetamol 1 g were administered before emergence. The patient‘s written informed consent was obtained. <h3>Results</h3> SESPB together with ACB produced 48 hours full knee analgesia (covering antero–medial, lateral, and posterior compartments) without motor block, representing an advantage for rehab. Paracetamol 1 g 3 a day was administered, with NRS score &lt; 4. <h3>Conclusions</h3> In our experience SESPB showed the potential to offer a full knee analgesia after TKA together with the ACB.
