Ağrı Patofizyolojisi, Rejyonel Anestezide Adjuvan İlaçların Yeri
Özet
Ağrı tedavisinde reseptör, reseptör alt grupları, mediatör çeşitliliği, anatomik lokalizasyon ve doz bağlı analjezik etkinin ortaya çıkıyor olması analjezi anlayışına her gün yenilikler katmaktadır. Günübirlik cerrahi prosedürlerin artması ve yaygınlaşması ile yan etkisi az analjezi stratejilerinin geliştirilmesi kaçınılmazdır. Adjuvan ilaç uygulamaları ile obstetrik, ortopedik ve genel cerrahi anestezisinde nöroaksiyal bloklar giderek daha konforlu uygulanır hale gelmiştir. Anestezi pratiğinde ultrasonografinin kullanılması ile de periferik, fasiyal plan ve nöroaksiyal bloklar yaygınlaşmıştır. Farklı doz ve farklı bölgesel uygulamalarla, periferik, nöroaksiyel bloklarda ve sistemik olarak, adjuvanlar gittikçe daha çok kullanılmaktadır. Ayaktan, günübirlik cerrahi tedavilerin artması, daha az opioid tercih edilen ağrı tedavilerini gerekli kılmaktadır. Daha düşük lokal anestezik dozları ve adjuvan ilaçlar ile uygulanması, blok ve analjezi kalitesini arttırıp, kısa blok süresi ve daha az yan etki ile hastaların postoperatif süreci çok daha konforlu geçirmesini sağlar. Lipozomal bupivacain gibi yeni ilaçların klinik uygulamada yer bulması, dexmedetomidin gibi yeni ve neostigmin, deksametazon, magnezyum, ketalar gibi eski ilaçların yeni anlayış ile kullanımı yetersiz ağrı tedavisinde arayış içinde olan klinisyenlere farklı çözümler sunmuştur. Adjuvan ilaçlar ile çalışmanın lokal anestezik sistemik toksitesinden uzaklaşma gibi önemli bir avantajı da vardır.
In pain management, the diversity of receptors, receptor subtypes, and mediators, along with anatomical localization and dose-dependent analgesic efficacy, continually brings new insights to our understanding of analgesia. With the rise and widespread adoption of ambulatory surgical procedures, the development of analgesia strategies with fewer side effects has become imperative. Thanks to adjuvant drug applications, neuraxial blocks are now administered with increasing safety and patient comfort in obstetric, orthopedic, and general surgical anesthesia. The expanding use of ultrasonography in anesthesia practice has similarly driven the adoption of peripheral, fascial plane, and neuraxial blocks. Adjuvants are increasingly utilized via different dosages and regional applications—peripherally, neuraxially, and systemically. The surge in outpatient and day-surgery procedures necessitates pain management approaches that minimize opioid reliance. Administering lower doses of local anesthetics combined with adjuvant drugs improves block and analgesia quality, shortens block duration, reduces side effects, and significantly enhances postoperative patient comfort. The clinical integration of novel formulations like liposomal bupivacaine, alongside new indications for both modern agents like dexmedetomidine and established drugs like neostigmine, dexamethasone, magnesium, and ketamine, provides clinicians seeking improved options for inadequate pain control with innovative solutions. Furthermore, working with adjuvant drugs offers the key advantage of minimizing the risk of local anesthetic systemic toxicity .
