Although lower-limb motor block intensity was significantly less in the levobupivacaine group (p<0.05), the overall duration of the motor block was similar in the two groups (p>0.05).

Abstract

Objective: The aim of this study was to investigate the onset, extent, and duration of sensory and motor block produced by 0.5% bupivacaine when compared with 0.5% levobupivacaine for epidural anesthesia. The hemodynamic and biochemical parameters were also recorded. Method: Sixty ASA I-II patients scheduled for elective lower limb surgery were randomized equally to receive either 0.5% bupivacaine (n=30,20 mL, 100 mg) or 0.5% levobupivacaine (n-30,20 mL, 100 mg). The sensorial and motor block characteristics, hemodynamic variables (mean arterial blood pressure, heart rate, peripheric oxygen saturation), and hepatic and kidney function tests of the two groups were compared. Results: The time to onset of adequate sensory block (T10 dermatome), time to maximum spread and time to two-segment regression of sensory block (bupivacaine: 118.10±12.18 min and levobupivacaine: 112.18+15.40 min) were similar in both treatment groups (p>0.05). The peak block height and the time to complete regression of the sensory block were T8 and 40 min longer, respectively in the levobupivacaine group (p<0.05). Although lower-limb motor block intensity was significantly less in the levobupivacaine group (p<0.05), the overall duration of the motor block was similar in the two groups (p>0.05). There were significant increases in hepatic enzymes in both treatment groups at 24 and 48 hours after epidural injection but these increases were within normal ranges and not clinically important. Conclusion: Levobupivacaine achieved less intense motor block, albeit with a longer duration of sensorial block compared to bupivacaine. Although increases in the hepatic enzymes provided no evidence that adverse effects on liver function might be a direct consequence of the local anesthetics, it is important to follow these parameters after epidural anesthesia especially in patients with higher values on liver function tests.

Özet

Amaç: Bu çalışmada, alt ekstremite cerrahisi için epidural anestezi uygulanacak hastalarda %0.5 bupivakain ile %0.5 levobupivakainin oluşturduğu duyusal ve motor blok düzeyleri ile hemodinamik ve biyokimyasal parametrelerin karşılaştırılması amaçlanmıştır. Yöntem: Çalışmaya epidural anestezi ile elektif alt ekstremite cerrahisi geçirecek ASA I-II grubundan 60 hasta dahil edildi. Hastalar randomize olarak %0.5 bupivakain (n-30, 20 mL, 100 mg) veya %0.5 levobupivakain (n=30, 20 mL, 100 mg) ile epidural anestezi yapılmak üzere iki eşit gruba ayrıldı: Hastaların duyusal ve motor blok özellikleri, hemodinamik değişkenleri (ortalama arteriyel kan basıncı, kalp atım hızı, periferik oksijen safürasyonu) ve karaciğer ve böbrek fonksiyon testleri gruplar arasında karşılaştırıldı. Bulgular: Duyusal bloğun Tıo dermatom düzeyine ulaşma, tepe noktası dermatomuna ulaşma ve iki dermatom gerileme süreleri (bupivakain: 118.10±12.18 dk ve levobupivakain:112.18±15.40 dk) gruplar arasında benzer bulundu (p>0.05). Levobupivakain grubunda tepe noktası dermatomu T8 ve duyusal bloğun tamamen ortadan kalkması 40 dk daha uzun olarak bulundu (p 0.05). Epidural enjeksiyonu takiben 24 ve 48. saatlerde her iki grupta da hepatik enzimlerde anlamlı artış oldu, ancak bu artışlar normal sınırlar içinde idi. Sonuç: Levobupivakainle, bupivakaine göre, daha uzun süreli duyusal blok sağlanırken, motor blok derecesi daha düşüktü. Epidural anestezi sonrası hepatik enzimlerdeki yükselme lokal anesteziklerin karaciğer üzerine direkt olumsuz etkileri olduğunu göstermemekle birlikte özellikle operasyon öncesi karaciğer fonksiyon testleri yüksek olan hastalarda bu parametreler yakından takip edilmelidir.
