Abstract

The aim of this study was to investigate the impact of the general anesthetic drug ketamine and premedication agents medetomidine and xylazine, and their reversal by atipamezole, on monitored anesthesia care values and ocular parameters such as intraocular pressure, horizontal pupillar diameter, and Schirmer tear test in cats. A randomized, single-blinded study was conducted. Twenty intact female cats (weiging between 2.2 and 3.6 kg, and 0.5 to 5.5 years of age) referred for ovariohysterectomy (OHE) procedure by the owners at regular intervals over 4 months were included in the study. The cats were randomly divided into two groups containing 10 animals in each group. The cats were premedicated with medetomidine 80 μg/kg intramuscular in group 1 while the cats in the 2nd group were premedicated with xylazine hydrochloride 2 mg/kg intramuscular. After the OHE procedure was ended, anesthesia regimes were reversed by using atipamezole 200 μg/kg intramuscularly. Monitoring of respiration rate, heart rate, mean arterial pressure, peripheral arterial oxygen saturation, and body temperature were conducted using a patient monitor at T0, T1, T2, T3, and T4 time points. Both groups showed declines in intraocular pressure and increases in horizontal pupil diameter after anesthesia induction (T0 vs. T1, all, P

Özet

Bu çalışmanın amacı, genel anestezik ilaç ketamin ve premedikasyon ilaçları medetomidin ve ksilazinin; ve bunların etkilerinin atipamezol ile tersine çevrilmesinin göz içi basıncı, yatay pupil çapı ve Schirmer gözyaşı testi gibi kedi oküler ve anestezi izlem parametreleri üzerindeki etkilerini araştırmaktı. Rastlantısal, tek tarflı kör bir çalışma yürütüldü. Sahipleri tarafından 4 aylık süre içerisinde ovaryohisterektomi operasyonu için başvurulan 20 erişkin dişi kedi (2,2 ila 3,6 kg ve 0,5 ila 5,5 yaş arasında) çalışmaya dahil edildi. Kediler, her grupta on kedinin olduğu iki gruptan birine rastlantısal olarak dahil edildi. Grup 1'de kediler kas içi 80 μg/kg medetomidin ile premedike edilirken grup 2 deki kediler kas içi ksilazin hidroklorür 2 mg/kg ile premedike edildi. Ovariohisterektomi işlemi bittikten sonra anestezik etki kasiçi atipamezol 200 μg/kg kullanılarak ters çevrildi. Solunum sayısı, kalp atım hızı, ortalama arter kan basıncı, periferik arteriyel oksijen düzeyi ve vücut ısının izlenmesi T0, T1, T2, T3 ve T4 zaman noktalarında hastabaşı monitör kullanılarak gerçekleştirildi. Her iki grup da anestezi indüksiyonundan sonra istatistiki olarak önemli olan göz içi basıncında düşüş ve yatay pupil çapında artış gösterdi (T0'a karşı T1, tümü, P
