Abstract

In this study, the cardiopulmonary and clinical effects of S (+) ketamine/medetomidine (S-K/MED) and ketaminrazemat/medetomidine (K-R/MED) combination on mice for anaesthesia were compared. A total of 20 adult female NMRImice (body weight 33-58 g) were used for this trial. Mice were divided into two groups. 75 mg/kg S-K and 0.25 mg/kg MED intraperitoneally (IP) were given to the Group 1 (G1), while 50 mg/kg K-R and 0.25 mg/kg MED intraperitoneally were given to the Group 2 (G2). The efficiency of anaesthetic agents were determined by clinical observations, which duration of induction, analgesia and immobilization, body temperature, respiratory rate (RR), peripheral oxygen saturation (SpO2 ), heart rate (HR). These parameters were measured and recorded at 10-minute intervals before and after administration of the anaesthetic agents. Analgesia lasted as a mean of 25 (15-35) min in G1 and 40 (30-60) min in G2 (p<0.05). The immobilization periods conducted in G1 and G2 were 56 (ranged between 50 and 65) min and 87 (ranged between 75 and 100) min, respectively (p<0.05). Temperatures reduced in both groups during anaesthesia. No significant differences between individual groups in the heart or respiratory rate as well as SpO2 value. Atipamezole (AT) application resulted in an increase in respiratory rate, and a small numbers of animals showed hyperventilation. As a results, it could be suggested that using S-K in combination with MED causes shorter duration time and less side effects after antagonisation of MED compared with K-R.

Özet

Bu çalısmada, farelerde anestezi için S(+)-ketamin-medetomidin (S-K/MED) kombinasyonu ile ketaminrazemat-medetomidin (K-R/MED) kombinasyonu klinik ve kardiyopulmoner etkileri yönünden karsılastırıldı. Toplam 20 eriskin disi fare iki farklı gruba ayrıldı. Grup 1 (n=10) 0.25 mg/kg MED ve 75 mg/kg S-K intraperitonal yolla uygulanırken, Grup 2 (n=10)’deki farelere yine aynı yolla 0.25 mg/kg MED ve 50 mg/kg K-R verildi. Anestezik ajanların etkileri; indüksiyon, analjezi, immobilizasyon süreleri, vücut ısısı, kalp frekansı, solunum frekansı ve perifer oksijen saturasyonu gibi klinik gözlemlere göre degerlendirildi. Bu gözlemler anesteziden on dakika önce ve anestezi boyunca onar dakikalık aralıklarla yapıldı. Analjezi süresi G1’de ortalama 25 dakika iken (15-35), G2’de ortalama 40 dakika (30-60) olarak ölçüldü (p<0.05). İmmobilizasyon süresi G1’de ortalama 56 dakika iken (50-65), G2’de ortalama 87 dakika (75-100) olarak ölçüldü (p<0.05). Her iki grupta da anestezi boyunca vücut ısısında düsüsler tespit edildi. Kalp frekansı, solunum frekansı ve perifer oksijen saturasyonu degerlerinde gruplarararasında istatistiki farklılıklar gözlenmedi. Atipemazol enjeksiyonundan sonra solunum frekansında artıs ve hiperventilasyon gözlendi. Sonuç olarak, S-K/MED kombinasyonunun K-R/MED kombinasyonuna göre gerek daha kısa süreli anestezi olusturması ve gerekse medetomidinin antagonize edilmesinden sonra daha az yan etki göstermesinden dolayı farelerde kullanımı önerilmektedir.
