Neonatal İshalli Buzağılarda Potasyum Düzeyleri ve Kalbin Elektrokardiyografisi

Bu çalışmanın amacı ishalli dehidre buzağılarda serum potasyum düzeylerini belirlemek ve kalbin elektrokardiyografik incelemesini yapmaktı. Çalışmada Fırat Üniversitesi Hayvan Hastanesine getirilen 4-12 günlük, 10 adet ishalli buzağı ile 5 adet sağlıklı buzağı kullanılmıştır. Ortalama potasyum düzeyleri orta derecede dehidrasyon saptanan buzağılarda 8.33 mEq/L, hafif derecede dehidrasyon saptanan buzağılarda ise 6.3 mEq/L olarak belirlenmiştir. Hiperkalemik kabul edilen orta derecede dehidrasyon belirlenen ishalli buzağılardaki elektrokardiyogram'da (EKG) P dalgasının olmadığı ve T dalgasının pik yaptığı, hafif dehidre ve orta derecede hiperkalemili buzağılarda ise P dalgasının amplitüdünün kısaldığı, QRS kompleksinin uzadığı ve T dalgasının negatif yönlü pik yaptığı gözlenmiştir. Sonuç olarak, ishalli buzağılarda belirli derecelerde hiperkaleminin gelişebileceği, bu durumun klinik olarak EKG muayenesiyle de ortaya konabileceği belirlenmiş ve ishalli dehidre buzağıların tedavi planlaması yapılırken hiperkalemiye karşı tedbirlerin alınmasının faydalı olacağı düşünülmüştür.

Potassium Levels and Heart Electrocardiogram in Calves with Neonatal Diarrhea

The aim of this study was to determine the serum potassium levels in dehydrated calves with diarrhea and was to make electrocardiographic examination of the heart. The study was performed on 10 calves with diarrhea and 5 healthy calves, 4-12 days old, brought into the Animal Hospital to University of Firat. The average potassium levels was determined in calves with moderate dehydration as 8.33 mEq/L, and in calves with mild dehydration as 6.3 mEq/L, respectivelly. The Electrocardiogram (ECG)results revealed the absence of P-waves and the the peak of the T-waves in hyperkalamic calves with moderate dehydration revealed, and reduded amplitude of the Pwaves, the prolonged QRS complex and negative peak of the T-waves in moderately hyperkalemic calves with light dehydration. As a result, hyperkalemia may develop in calves with diarrhea in certain degree, this is clinically determined and may be introduced in the ECG examination. Taking preventive measures against hyperkalemia could be useful in planning treatment od diarrheic and dehydrate calves.
