Comparison of Perioperative Serum Glucose and Serum Fructosamine Levels in Cats

Abstract

In this study, the changes in serum glucose and fructosamine levels according to the sampling time in cats anaesthetised for castration and ovariohysterectomy were investigated. The study material consisted of 25 cats aged between 6 months and 2 years. Blood samples were collected from the anaesthetised cats (medetomidine, butorphanol, ketamine) before anaesthesia, at the beginning of anaesthesia, before awakening from anaesthesia and after awakening from anaesthesia. Glucose, fructosamine, cholesterol, triglyceride, total protein and albumin levels were measured in the sera obtained. In the statistical comparison made according to the measurement times, it was found that serum glucose level changed significantly. However, no statistically significant difference was found in serum fructosamine levels. It was evaluated that the variation in glucose levels in the perioperative period may be related to anaesthetic agents, and although there was no statistically significant change in fructosamine levels, one of the reasons for the increase in glucose levels observed in the perioperative period was probably operation stress. The results of the study showed that serum glucose measurements are important in perioperative glycaemic control of cats, and serum fructosamine measurements have diagnostic value in the exclusion of possible perioperative hyperglycemia that may develop for different reasons. The stable serum fructosamine level in the perioperative period can be accepted as an indication that it was not affected by the anaesthetic agents used in this study.

Kedilerde Perioperatif Serum Glukoz ve Serum Fruktozamin Seviyelerinin Karşılaştırılması

Öz

Bu çalışmada kastrasyon ve ovariohisterektomi operasyonu amacıyla anesteziye alınan kedilerde örnekleme zamanına göre serum glukoz ve fruktozamin seviyelerinde meydana gelen değişim araştırıldı. Çalışma materyalini 6 ay ila 2 yaş arasında 25 kedi oluşturdu. Anesteziye (medetomidin, butorfanol, ketamin) alınan kedilerden; anestezi öncesinde, anestezi başlangıcında, anesteziden uyandırmadan önce ve anesteziden uyandıktan sonra kan örnekleri alındı. Elde edilen serumlarda glukoz, fruktozamin, kolesterol, trigliserid, total protein ve albümin konsantrasyonları ölçüldü. Ölçüm zamanlarına göre yapılan istatistiksel karşılaştırmada; serum glukoz düzeyinin anlamlı şekilde değiştiği tespit edildi. Bununla birlikte serum fruktozamin seviyelerinde istatistiksel olarak anlamlı bir fark bulunmadı. Perioperatif dönemde glukoz seviyelerinde meydana gelen varyasyonun anestezik ajanlarla ilişkili olabileceği, fruktozamin düzeylerinde istatistiksel olarak önemli bir değişim görülmemesine rağmen, glukoz düzeyinde perioperatif dönemde gözlenen artışın bir nedeninin de olasılıkla operasyon stresi olduğu değerlendirildi. Çalışma sonucu; kedilerin perioperatif glisemik kontrollerinde serum glukoz ölçümlerinin önemli olduğunu, farklı nedenlerle gelişebilecek olası perioperatif hipergliseminin dışlanmasında ise serum fruktozamin ölçümlerinin diyagnostik yönden değer taşıdığını gösterdi. Perioperatif dönem serum fruktozamin seviyesinin stabil oluşu, bu çalışmada kullanılan anestezik ajanlardan etkilenmediğinin bir göstergesi olarak kabul edilebilir.
