Abstract

This study is aimed to compare the effects of propofol, sevoflurane and isoflurane on cerebral blood flow velocity by using Transcranial Doppler ultrasonography throughout perioperative period. We enrolled 30 healty, male subjects for the study and randomized for three groups [propofol (n=10), sevoflurane group (n=10), isoflurane group (n=10)]. We measured flow velocity of right middle cerebral artery (VMCA), by using Transcranial Doppler ultrasonography from temporal bone window throughout perioperative period [preoperative, intraoperative (under normocapnic and hipocapnic conditions) and postoperative]. After induction of anesthesia using propofol (2mg/kg) and fentanyl (2 µg/kg), laryngeal mask airway was inserted and the anesthesia was maintained with either propofol infusion, or sevoflurane or isoflurane inhalation. There were no significant differences between preoperative and postoperative VMCA measurements for all the groups (p>0,05). The VMCA values under normocapnic conditions were decreased significantly according to awake values in propofol group (p0,05). Under hipocapnic conditions, VMCA decreased significantly in all groups (p

Özet

Bu çalışma, anestezik ajanlardan propofol, sevofluran ve izofluranın perioperatif süreçte, beyin kan akımı üzerine etkilerini karşılaştırmak amacıyla yapılmıştır. Çalışmaya, 30 sağlıklı erkek olgu alınmış ve rastgele üç gruba ayrılmıştır: Propofol grubu (n=10), Sevofluran grubu (n=10), İzofluran grubu (n=10). Bütün gruplarda, preoperatif dönemde, transkraniyal doppler ultrasonografi ile sağ temporal kemik pencereden orta serebral arterdeki kan akım kızı ölçülmüştür. Her üç grupta anestezi indüksiyonu propofol (2mg/kg) ve fentanil (2 µg/kg) ile yapılmış ve olgularda havayolu açıklığı laringeal maske ile sağlanmıştır. Anestezinin idamesinde; Propofol grubunda, 5-10 mg/kg/sa propofol infüzyonu, Sevofluran grubunda, %2 konsantrasyonda sevofluran ve İzofluran grubunda, %1,5 konsantrasyonda izofluran inhalasyonu kullanılmıştır. İntraoperatif dönemde, normokapnik ve hipokapnik koşullarda, iki kez, transkraniyal doppler ultrasonografi ile arter kan akım hızı ölçümü yapılmıştır. Bu ölçüm, erken postoperatif dönemde de yapılarak kaydedilmiştir. Buna göre, her üç grupta, preoperatif ve postoperatif ölçümler arasında anlamlı bir fark ortaya çıkmamıştır (p>0,05). Preoperatif ölçümler ile normokapnik süreçteki ölçümler arasında; propofol grubunda anlamlı bir düşüş saptanırken (p0,05). Hipokapnik süreçte ölçümler her üç grupta da anlamlı olarak düşmüştür (p>0,05). Sonuç olarak, özellikle nörocerrahi geçirecek olgularda propofol infüzyonunun daha güvenli olduğu ortaya çıkmıştır
