Neonatal İshalli Buzağılarda Sıvı Replasmanı Öncesi ve Sonrası Vena Kava Kaudalis Çapının Değerlendirilmesi ; Evaluation of Vena Cava Caudalis Diameter Before and After Fluid Replacement İn Calves with Neonatal Diarrhea

The aim of this study were to evaluate the caudal vena cava diameter and caval index before and during treatment with ultrasonography in dehydrated calves, to obtain more objective criteria for the determination of the degree of dehydration, and to investigate the correlation of CVC diameter and KI with clinical and laboratory parameters. The study's animal material consisted of calves of various breeds and genders, aged 2-15 days, which were brought in with the complaint of acute diarrhea in the neonatal period. The calves were divided into two groups as moderate dehydration (Group I) and severe dehydration (Group II) by scoring the degree of dehydration according to clinical examination findings. Fluid therapy and supportive treatment were performed to all calves. Clinical, monitoring, laboratory and ultrasonographic examinations of the calves were performed before the treatment, immediately after the fluid treatment, and at the 8th, 24th, and 48th hours after the treatment. It was determined that the calves included in the study had watery diarrhea, dehydration, capillary refill time prolongation, hypothermia and an absence of the sucking reflex before the treatment. It was determined that 14 of the neonatal calves with diarrhea were septicemic and 10 of them had nonsepticemic diarrhea. Leukocytosis, hemoconcentration, hypotension, metabolic acidosis, hyperkalemia and hyperlactatemia were detected in the calves included in the study. A decrease in CVCmax and CVCmin values and an increase in KI were detected in all calves before treatment. After the treatment, improvement of clinical, hematological and monitoring findings was detected. A significant increase in CVCmax and CVCmin values and a significant decrease in KI values were detected in all calves after treatment. In the correlation analysis, positive and negative correlations were determined between CVCmax, CVCmin and KI and degrees of dehydration, capillary refill time, posture, sucking reflex, WBC, RBC, HCT, Hb, pH, sO2, K+ , BE, HCO3 - , SBP, DBP and ...
