Abstract

Diarrhea in neonatal calves is due to one or more causes. Strong
ion (metabolic) acidosis is common in diarrheic calves. Clinical
signs associated with metabolic acidosis are vague and nonspecific.
However, the calf’s age can be used to predict the severity
of metabolic acidosis, because one weak old diarrheic calves are
less acidemic than older calves despite they have similar clinical
signs. Moreover, the suckling reflex is closely associated with
base excess parameters. One of the most important factors for
decreasing mortality rates associated with diarrhea in calves is
parenteral and oral administration of appropriately formulated
electrolyte solutions. Inclusion of an alkalinizing agent is
required to correct systemic metabolic acidosis. Bicarbonatecontaining
fluids are more effective at rapidly correcting severe
acidemia, since bicarbonate reacts directly with H+
ions. Lactated
Ringers solution or Acetated Ringers solutions can be used to
correct mild to moderate acidosis.

İshalli neonatal buzağılarda strong (metabolik) ion asidozisin tedavisine genel bakış

Abstract

Neonatal buzağı ishallerine bir veya birden daha fazla etken
neden olabilir. İshalli buzağılarda strong ion (metabolic)
asidozis yaygın olarak gözükür. Strong ion asidozisle ilişkili
klinik semptomlar spesifik olmayıp belirsizdir. Fakat strong ion
asidozisin şiddetinin tahmininde buzağının yaşı göz önünde
bulundurulabilir. Çünkü aynı klinik bulgulara sahip buzağılardan
yaşamının ilk haftasındaki buzağılar, bir haftalıktan büyük
buzağılara kıyasla daha az asidemiktir. Ayrıca emme refleksi ile
baz açığı değeri arasında yakın ilişki bulunmaktadır. Buzağılarda
ishalle ilişkili ölümün azaltılmasında en önemli faktörlerden biri
uygun oral veya intravenöz sıvıların kullanılmasıdır. Sistemik
metabolik asidozisisi düzeltmek için uygun alkalize ajanların
kullanılması gerekmektedir. Bikarbonat kandaki H+
iyonu
ile direk reaksiyona girdiğinden dolayı, bikarbonat içeren
intravenöz sıvılar şiddetli asideminin düzeltilmesinde oldukça
etkilidir. Laktatlı ringer veya asetatlı ringer solüsyonlar ise hafiforta
derecede metabolik asidozisi düzeltmede tercih edilir.
