Anesthesia and Vital Sign Monitoring in Pigs

To begin, sedative drugs were delivered through an intramuscular injection of Sumianxin (0.2ml/kg) and 3% phenobarbital (1ml/kg). It took about 5-10 minutes for the pig to fall asleep. The vein channel was established through the ear vein, and the intravenous indwelling needle was inserted. 8-10ml of general anesthesia drug was injected (propofol injection, 2mg/kg, Fentanyl citrate injection, 2ug/kg, Rocuronium injection, 1mg/kg). Endotracheal intubation was performed with an insertion depth of about 28cm. After successful intubation, a ventilator was connected, and anesthetics were given continuously. The vital signs such as respiration, heart rate, and electrocardiogram were observed.
