Abstract

Surgery must often be performed in fields where only simple equipment and facilities are available for cattle practice, and anesthesia with minimal procedures should be improved for sufficient surgery in the field and on farms. The study aimed to investigate total intravenous anesthesia (TIVA) using xylazine and propofol to improve the anesthesia protocol for field surgeries in calves on farms. Fourteen calves undergoing laparotomy (every seven cases of herniorrhaphy for umbilical hernia repair and cryptorchidectomy) were assigned to this experiment and randomly divided into two groups using TIVA: continuous intravenous infusion with only xylazine (XY, 0.24-0.26 mg/kg/h), and xylazine and propofol (XYP, 0.24 mg/kg/h and 12 mg/kg/h, respectively). The respiratory rate (RR), heart rate (HR), body temperature, saturation of percutaneous oxygen (SpO2), blood pressure, and frequency of body movement (FBM) were recorded and compared between the two anesthesia protocols during laparotomy. Spontaneous respiration was maintained during surgery in all cases. RR was significantly decreased, and FBM slightly decreased in XYP, whereas SpO2 and HR in XYP were significantly higher than in XY. The results indicated that TIVA with xylazine and propofol could provide stable vital signs under anesthesia while maintaining spontaneous respiration, which could help field surgery more safely and accurately.
