Abstract

Introduction: The purpose of our study, was to investigate the effects of LA given in a single or fractioned dose on hemodynamics during epidural anesthesia applied to risky patients.Materials and Method: 80 patients of 50 years or above age who were to receive TUR-P surgery, who were in ASA III-IV group were included in the study. They were first divided into 2 groups according to their EFs, then further subdivided into 4 groups of 20 individuals according to two different application methods of the LA, being single dose and fractional. Hemodynamics of the patients were recorded continuously during the intervention.Results: The change in hemodynamic parameters of the patients was found to be more pronounced in the group with lower EF. What's more, among patients with low EF, it was observed that the decrease in hemodynamic parameters started later and lasted shorter in the group received fractional LA.Conclusion: The fast developing sympathetic block after application of a single dose of LA cannot be compensated in patients with low cardiac reserve and the consequences can be serious. It was concluded that the fractioned application of LA during epidural anesthesia in the old patient with cardiac risks may progress more stable in relation to haemodynamics.

Özet

Giriş: Çalışmamızda riskli hastalarda uygulanan epidural anestezide, hastaların ejeksiyon fraksiyonunun ve lokal anesteziğin tek doz veya fraksiyone uygulamasının hemodinami üzerindeki etkilerini araştırmayı amaçladık.Gereç ve Yöntem: Çalışmaya TUR-P cerrahisi uygulanacak elli yaş ve üzeri, ASA III-IV grubundaki 80 hasta alındı. Hastalar EF'lerine göre iki gruba ayrıldıktan sonra, tek doz ve fraksiyone olmak üzere LA'nın iki farklı uygulama yöntemine göre yirmişer kişilik dört alt gruba ayrıldı. Epidural anestezi %2 lidokain ile sağlandı. Hastaların hemodinamik parametreleri girişim süresince kaydedildi.Bulgular: Hastaların hemodinamik parametrelerindeki değişimin EF'si düşük olan gruplarda, EF'si yüksek olan gruplara göre daha belirgin olduğu saptandı. Aynı zamanda EF'si düşük olan gruplardan LA'nın fraksiyone uygulandığı grupta hemodinamik parametrelerdeki azalmaların tek doz uygulamanın yapıldığı gruba göre daha geç başladığı ve daha kısa sürdüğü gözlendi.Sonuç: Lokal anesteziğin tek doz olarak uygulanmasıyla hızla gelişen sempatik blok, kardiyak rezervi yaşlanma veya hastalığa bağlı olarak azalmış hastalarda kompanse edilememekte ve sonuçları daha ağır olabilmektedir. Çalışmamızda yaşlı ve kardiyak açıdan riskli hastalarda epidural anestezide lokal anesteziğin fraksiyone uygulanmasının hemodinamik açıdan daha stabil seyredeceği ve bu nedenle daha az olumsuzluk yaratacağı sonucuna varıldı.
