Göğüs Cerrahisinin Postoperatif Analjezisinde Bölgesel Teknikler
Özet
Göğüs cerrahisi sonrası görülen şiddetli akut ağrının yönetimi, hastaların iyileşme süreci ve komplikasyonların önlenmesi açısından kritiktir. Geleneksel olarak torasik epidural analjezi (TEA) altın standart kabul edilse de hipotansiyon ve üriner retansiyon gibi yan etkiler nedeniyle alternatif yöntemler öne çıkmaktadır. Özellikle ultrason (US) rehberliğinin gelişimi; torakal paravertebral blok (TPVB), erektör spina plane blok (ESPB), retrolaminar blok (RLB) ve serratus anterior plane blok (SAPB) gibi daha güvenli ve az invaziv tekniklerin kullanımını artırmıştır. TPVB, TEA ile benzer etkinlik gösterirken daha az yan etki profiline sahiptir. Yeni nesil fasyal plan bloklarından ESPB ve RLB, lokal anestetiğin paravertebral alana dolaylı yayılımı prensibiyle çalışarak teknik kolaylık ve güvenlik sağlar. Video yardımlı torakoskopik cerrahi (VATS) gibi modern prosedürlerde bu az invaziv yöntemler daha çok tercih edilmektedir. Sonuç olarak, US eşliğinde uygulanan bu bölgesel teknikler multimodal analjezinin ayrılmaz bir parçası haline gelmiştir. Ancak, her yöntemin etkinliğini tam olarak belirlemek için cerrahi prosedür ve hasta özellikleri göz önünde bulundurularak daha fazla klinik çalışmaya ihtiyaç duyulmaktadır.
Management of severe acute pain following thoracic surgery is critical for the recovery process and prevention of complications. While thoracic epidural analgesia (TEA) is traditionally considered the gold standard, alternative methods are emerging due to side effects like hypotension and urinary retention. Specifically, the advancement of ultrasound (US) guidance has increased the use of safer, less invasive techniques such as thoracic paravertebral block (TPVB), erector spinae plane block (ESPB), retrolaminar block (RLB), and serratus anterior plane block (SAPB). TPVB demonstrates similar efficacy to TEA but with a better side-effect profile. Next-generation facial plane blocks like ESPB and RLB provide technical ease and safety by working on the principle of indirect spread of local anesthetic to the paravertebral space. In modern procedures such as video-assisted thoracoscopic surgery (VATS), these less invasive methods are preferred. Consequently, these US-guided regional techniques have become an integral part of multimodal analgesia. However, more clinical studies considering surgical procedures and patient characteristics are needed to fully determine the effectiveness of each method.
