Background: Effective postoperative multimodal analgesia facilitates early physical rehabilitation to maximize the postoperative range of motion and prevent joint adhesions following total knee arthroplasty (TKA). Adductor canal block has been reported as a supplement to multimodal analgesia protocols in patients undergoing TKA. The use of ultrasound (US) guidance has improved the success rates of the blocks compared with blind approaches. Case Presentation: This report described two elderly patients undergoing TKA with ACB as postoperative pain management, resulting in adequate pain control during the postoperative period. Conclusion: Adductor canal block can be used to optimize multimodal analgesia by reducing opioid requirements and enhancing recovery after TKA.
Nyeri neuropatik akut pascabedah Seksio Sesarea (SS) ditandai dengan adanya tanda dan gejala nyeri neuropatik yang berbeda dari nyeri nosiseptif berupa alodinia dan hiperalgesia, yang ditemukan pada periode awal hingga 1 bulan pascabedah. Nyeri neuropatik akut dapat terjadi akibat cedera langsung pada saraf iliohipogastrika dan ilionguinal akibat pembedahan SS, yang selanjutnya memicu pelepasan ektopik dan perubahan kanal ion pada saraf perifer, serta memicu terjadinya sensitisasi sentral. Meskipun demikian, disfungsi saraf pascabedah biasanya merupakan kombinasi dengan nyeri nosiseptif akibat kerusakan jaringan dan peradangan. Skrining perioperatif dan faktor risiko dapat menggunakan alat skrining Douleur Neuropathique en 4 (DN4) atau DN2 untuk mencegah perkembangan menjadi nyeri persisten. Pendekatan saat ini untuk pencegahan nyeri neuropatik kronis bertujuan untuk mengoptimalkan analgesia dan mengurangi nosisepsi dari nyeri akut dengan memodifikasi teknik bedah dan memilih anestesi regional. Pengobatan nyeri neuropatik memerlukan kombinasi terapi farmakologis, fisik, dan terapi perilaku. Beberapa terapi lini pertama pada penanganan nyeri neuropati akut seperti gabapentinoid, opioid, antagonis reseptor NMDA, hingga terapi stimulasi listrik transkutan dan stimulasi medula spinalis menjadi pertimbangan untuk nyeri neuropatik akut.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
