Abstract

Background: Intrathecal α2 agonists prolong the duration of action of local anesthetics and reduce the required dose. Dexmedetomidine is an α2 receptor agonist and its α2/α1 selectivity is 8 times higher than that of clonidine. Aims: In this study, we aimed to investigate the effect of adding dexmedetomidine to intrathecal levobupivacaine on the onset time and duration of motor and sensory blocks. Study Design: Randomized controlled study. Methods: Patients were randomly assigned into two groups. Group L (n= 30) patients received 3 mL (15 mg) of 0.5% levobupivacaine +0.3 mL normal saline and Group LD (n= 30) patients received 3 mL (15 mg) of 0.5% levobupivacaine + 0.3 mL (3 μg) dexmedetomidine. Sensory block onset time, block reaching time to T10 dermatome, the most elevated dermatome level, two dermatome regression time, sensory block complete regression time as well as motor block onset time, reaching Bromage 3 and regressing to Bromage 0 were recorded. Results: Sensory and motor block onset times were shorter in Group LD than in Group L (p<0.001). The regression of the sensory block to S1 dermatome and Bromage 0 were longer in Group LD than Group L (p<0.001). The two dermatome regression time was longer in Group LD than Group L (p< 0.001). There were no statistically significant differences between groups in blood pressure and heart rate. There was no statistically significant difference between groups when adverse effects were compared. Conclusion: We conclude that intrathecal dexmedetomidine addition to levobupivacaine for spinal anaesthesia shortens sensory and motor block onset time and prolongs block duration without any significant adverse effects. Turkish Başlık: Transuretral Endoskopik Cerrahide Spinal Levobupivacaine Eklenen Deksmedetomidinin Etkileri Anahtar Kelimeler: Deksmedetomidin, levobupivakain, spinal blok. Arka Plan: İntratekal uygulanan α2 agonistler lokal anestezi etki süresini uzatır ve gerekli doz ihtiyacını azaltır. Deksmedetomidin bir α2 reseptör agonistidir ve α2/ α1 selektivitesi klonidinden 8 kat daha yüksektir. Amaç: Bu çalışmada spinal anestezide levobupivakaine eklenen deksmedetomidinin duyusal ve motor blok başlama zamanına ve blok süresine etkisini araştırmayı amaçladık. Çalışma Tasarımı: Randomize kontrollü çalışma Yöntemler: Bu çalışmaya spinal anestezi altında transuretral prostat ya da mesane tümörü rezeksiyonu planlanan 60 hasta alındı Hastalar rastgele iki gruba ayrıldı. Grup L (n=30) için % 0.5 lik levobupivakainden 3mL (15mg) + 0.3 ml normal salin, Grup LD (n=30) için % 0.5 lik levobupivakainden 3ml (15mg) + 3μg deksmedetomidin (0.3ml) uygulandı. Duyusal blok başlama zamanı, T10 dermatomuna ulaşma zamanı, en yüksek dermatom seviyesi, iki dermatom gerileme zamanı ve duyusal bloğun tam geri dönme zamanı kaydedildi. Motor blok başlama zamanı, Bromage 3'e ulaşma zamanı ve Bromage 0 a gerileme zamanı kaydedildi. Bulgular: Duyusal ve motor blok başlama süresi Grup LD de Grup L den daha kısa idi (p<0.001). Duyusal bloğun S1 dermatomuna ve Bromage skorunun 0 a geri dönme süresi Grup LD de Grup L den daha uzundu (p<0.001). Duyusal bloğun iki dermatom gerileme süresi de Grup LD de Grup L den daha uzundu. Grupların kan basıncı ve kalp hızı değerleri arasında istatistiksel olarak anlamlı fark yoktu. Gruplar arasında yan etki görülme sıklığı açısından istatistiksel olarak anlamlı fark yoktu. Sonuç: Spinal anestezide levobupivakaine eklenen intratekal deksmedetomidinin, belirgin bir yan etkiye neden olmadan duyusal ve motor blok başlama süresini kısalttığı ve blok süresini uzattığı sonucuna vardık.
