[2022/03/30, 11:48:01] Joel Alves: Does anyone have any good suggestions of where I could get a good arterial sample on hippo for blood gas? [2022/03/30, 11:57:32] Mikidadi: What about the coccygeal artery?? [2022/03/30, 15:46:30] Leith Meyer: Hi Joel. At this stage probably the only place and not easy to know if you are in an artery or vein, but if you get the syringe self-filling it’s probably the artery. You could try the inner thigh of the hind leg if they are lateral. I have felt a pulse there, but you may need some luck or ultrasound to hit it. [2022/03/30, 16:36:12] Joel Alves: Thanks a lot. Will give you guys some feedback if we manage and get a good sample. Will certainly give it a good crack! [2022/03/31, 01:52:18] Scott B. Citino: When doing our anaesthesia studies on hippos, we were generally able to get multiple arterial samples from the caudal artery - just make sure the syringe is self-filling.
