Abstract

In this study we compared 0.5 % isobaric and hyperbaric bupivacaine for unilateral spinal anaesthesia in patients undergoing lower extremity surgery. Spinal anaesthesia was performed with 22G Quincke-Babcock spinal needles from L 4-5 intervertebral space. Patients were divided randomly into two groups. Patients in Group I were (n=25) turned to lateral decubitus position, upper leg being the dependent leg and 8 mg 0.5 % isobaric bupivacaine was injected. Patients in Group II were turned to (n=25) lateral decubitus position, lower leg being the dependent leg and 8 mg 0.5 % hyperbaric bupivacaine was injected. In both groups, the bevel of spinal needle was turned towards dependent leg and drug was injected in 45 seconds. Patients stayed in lateral decubitus position for 20 minutes and then were turned to supine position. Mean blood pressure, heart rate, motor blockade (Bromage scale), sensorial blockade (pin-prick test) with 3 minutes intervals in lateral position and 5 minutes intervals after turning supine were recorded. As a result more unilateral spinal anaesthesia was observed with 0,5 % hyperbaric bupivacaine and recovery from motor block was shorter than patients receiving 0,5 % isobaric bupivacaine.

Özet

Çalışmamızda tek bacağı ilgilendiren alt ekstremite cerrahisi uygulanacak olgularda tek taraflı spinal anestezi oluşturmak için % 0.5 izobarik ve hiperbarik bupivakain karşılaştırıldı. Tüm olgulara spinal anestezi, lateral pozisyonunda 22G Quincke-Babcock tipi spinal iğne ile L 4-5 vertebra aralığından uygulandı. Yan yatırılan hastalar 2 gruba ayrıldı. I. gruba (n=25) etkilenen bacak üst tarafa alınarak 8 mg. % 0.5 izobarik bupivakain, II. gruba (n=25) ise etkilenen bacak alt tarafa alınarak 8 mg % 0.5 hiperbarik bupivakain uygulandı. Her iki grupta da kullanılan spinal iğnenin uç açıklığı etkilenen bacağa yönlendirilerek lokal anestezik solüsyon yaklaşık 45 sn.de intratekal aralığa enjekte edildi. Hastalar yan pozisyonda yatarak 20 dk. bekletildikten sonra sırt üstü pozisyona alındı. Tüm olguların; ortalama kan basınçları, kalp atım hızlan, motor blok (bromage skalası) ve duyusal blok derecesi (pin-prick testi) yan pozisyonda yattığı 20 dk. süresince 3 dk. aralarla, sırt üstü pozisyonda 5 dk. aralarla kaydedildi. Sonuç olarak % 0.5 hiperbarik bupivakain kullanılan olgularda, daha fazla tek taraflı spinal anestezi oluşması ile beraber motor bloğun çözülme zamanlarının % 0.5 izobarik bupivakain kullanılan olgulardan daha kısa olduğu gözlendi.
