(2019·昆明调研)When she was found off the coast of California four years ago, the fur seal, known as Ziggy Star, was skinny and fragile. She was unfit to return to the wild. And though a professional rescue team took her in to care for her, Ziggy continued to decline. “I wouldn't have given her next week，” says Uriarte, a surgeon who led a recent first-of-its-kind brain operation on the seal.
The operation was the first of its kind to treat hydrocephalus in fur seals. The surgical team at Tufts was unable to find any documented evidence of a similar procedure, so they needed a lot of preparation to operate on Ziggy's brain. The biggest concern in operating on Ziggy was how to control the animal's anesthesia (麻醉). “When they're under anesthesia their body's reaction includes decreasing their heart rate, blood pressure, and breathing，” says Flower, who observes Ziggy and the other animals' care, describing the special challenges of operating on seals. On the day of the surgery, Flower says that she and her team “were all quite anxious not knowing what would happen”. Moving quickly was extremely important; the longer she was under anesthesia, the more likely that she could lose her breathing, says the surgeon. The seal has been kept on land to prevent water from entering the cut on her head.
Now, Ziggy is eating a full diet and is beginning to gain weight again. “Recently I've allowed her to go swimming，” says Flower. However, the source of Ziggy's neurological disorder (神经紊乱) is still a mystery. “My theory is that when she was found, she had a head injury，” Uriarte says. “Hit by a boat maybe ... That happens a lot with seals.” Flower is less willing to guess. “I don't think there's enough information to make that assumption. We just don't know what happened to her.”
