Abstract

Objective: The aim of this study is to investigate the effect of day and night administration of desflurane anaesthesia on melatonin levels in rats. Methods: Twenty-four 15-day-old rats were included in the study and were divided into four groups. The rats were anaesthetised between 19:00-01:00 (night group) and 07:00-13:00 (day group) with 5.7% desflurane concentration in 6 L min-1 100% oxygen. 6 L min-1 oxygen was administered to the control groups. At the end of 6 h of anaesthesia, blood samples were taken, and rats were sacrificed. Blood samples were centrifuged and melatonin levels from plasma samples were measured with radioimmunoassay. Results: There was a statistically significant difference between the groups (p=0.007). Between group day control and group night control there was a statistically significant difference (p=0.042). Further, there was a significant difference between group day control and night desflurane (p=0.024). We could not find any difference between other groups. Conclusion: This study showed that 6 hours of 5.7% desflurane anaesthesia during day and night hours did not significantly change melatonin levels.

Özet

Amaç: Bu çalışmanın amacı ratlarda gece-gündüz desfluran uygulamasının melatonin düzeyi üzerine etkisinin araştırılmasıdır. Yöntemler: Çalışmaya 15 günlük 24 adet rat alındı ve rastgele 4 gruba ayrıldı. Ratlara bahar döneminde 19:00-01:00 (gece grubu) ve 07:00-13:00 (gündüz grubu) saatleri arasında 6 L dk-1 akım hızında %100 oksijen içinde %5,7 desfluran uygulandı. Kontrol gruplarına ise aynı zaman süresince 6 L dk-1 akım hızında oksijen uygulandı. Altı saatlik sürenin sonunda kan örnekleri alındıktan sonra ratlar sakrifiye edildi. Alınan kanlar santrifüj edildi ve elde edilen plazmalarda melatonin düzeyleri radioimmünoassay yöntemi ile ölçüldü. Bulgular: Tüm gruplar karşılaştırıldığında gruplar arasında anlamlı fark saptandı (p=0,007). Gündüz kontrol ve gece kontrol grupları karşılaştırıldığında gruplar arasında anlamlı fark oldu- ğu görüldü (p=0,042). Ayrıca gündüz kontrol ve gece desfluran grupları arasında anlamlı fark saptandı (p=0,024). Diğer gruplar arasında anlamlı fark saptanmadı. Sonuç: On beş günlük ratlarda yaptığımız bu çalışma ile altı saatlik %5,7 konsantrasyondaki desfluranın gece veya gündüz uygulanmasının melatonin düzeyini etkilemediğini saptadık.
