Özet
Amaç: Sabit dozda kullanılan levobupivakainin iki farklı volüm ve konsantrasyonunun çocuklarda kaudal blok kalitesi ve postoperatif analjezi üzerine etkileri kıyaslandı. Gereç ve Yöntemler: Ürogenital cerrahi geçirecek 3-8 yaş arası 40 çocuğa kaudal blok için 2 mg/kg levobupivakain, yüksek (1 mL/kg; Grup Y; n=20) veya düşük (0,5 mL/kg; Grup D; n=20)hacimde uygulandı. İnspiratuar sevofluran konsantrasyonunu artırmayı gerektiren intraoperatif hemodinamik yanıtlar vepostoperatif analjezi süresi değerlendirilen öncelikli parametrelerdi. Bulgular: Her iki grupta da inspire edilen sevofluran konsantrasyonunu artırmayı gerektirecek hemodinamik yanıt gözlenen hasta yoktu. Analjezi süresi Grup Y de Grup D’ye göre anlamlı olarak uzundu (sırasıyla 825±103 dk ve 587±98 dk; p=0,029).Operasyon sonrası ilk saatte hastaların hiçbirinde motor blok bulgusu gözlenmedi. Sonuç: Levobupivakainin yüksek volüm/düşük konsantrasyonu ile uygulanan kaudal blok, düşük volüm/yüksek konsantrasyonu kıyaslandığında daha uzun süre postoperatif analjezi sağlar.

Intraoperative hemodynamicresponses requiring an increase in inspired sevoflurane concentration, and duration of postoperative analgesia were theprimary outcome measures.Results: There were no patients in any group who requiredan increase in inspired sevoflurane concentration to blockthe hemodynamic response during the operation. Duration ofanalgesia was significantly longer in Group H than in GroupL (825±103 min vs. 587±98 min respectively, p=0.029). No signs of motor block were observed after the first postoperative hour in any of the patients.Conclusion: Caudal block with a high volume/low concentration of levobupivacaine provides longer duration of postoperative analgesia compared to low volume/high concentration of levobupivacaine in children.
