Ultrasound-Guided Anesthetic Monitoring in Primates

The ultrasound procedure was performed using a GE LOGIQ P5 ultrasound imaging system after the onset of short-acting Zoletil anesthetic (0.1 mg/kg i.m.); then, the animal was safely secured to the examination table. Abdominal ultrasonography of monkey 010139 affected by PKD and PLD was performed after it exhibited depression and poor appetite. The other PKD-affected monkey was diagnosed during necropsy; therefore, no relevant ultrasonography results were available. Animal IDs and health status were confirmed before biopsy procedures. Animals were anesthetized with ketamine, 10 mg/kg i.m., and hair on the area of skin that covered the right chest and the liver lobe was removed using a razor. The imaging probe was placed on the abdomen. Ultrasonographic examinations were conducted as previously described (16 ). The liver and other organs were imaged transcutaneously using the GE LOGIQ P5 ultrasound imaging system, with 10 L and 4°C probes (GE Healthcare, USA).
