"...s/he is the most emaciated turtle we’ve ever admitted. Surprisingly, this green had a moderate blood glucose level of 48 and a high PCV of 31 (% of red blood cells), values very odd for a turtle so malnourished. Blood sodium levels were extremely high, likely caused by severe dehydration, so aggressive fluid therapy began immediately. This turtle also had a fairly severe arrhythmia (irregular heart beat) that normalized somewhat after treatments were administered.
4 May 2015: It is astounding that this severely ill turtle is still alive and fighting for survival in our hospital, as initial prognosis was extremely poor. Our vet, Dr. Boylan, has been closely monitoring this case to ensure the correct fluids are provided as needed. Barnacle Bob has no appetite and is refusing both vegetation and fish, and so parenteral nutrition in the form of an intravenous fat emulsion, Intralipid, is being provided directly into the bloodstream almost daily. This turtle is able to swim for short periods of time (up to an hour) in saltwater, but becomes exhausted quickly and so is primarily being housed on a soft bed of wet foam."
"Conscientious fishermen at Myrtle Beach State Park’s (MBSP) fishing pier foul-hooked this small loggerhead in the front flipper. Upon bringing the turtle up with a large dip net to remove the hook prior to release, they noticed the turtle appeared to be in poor health and contacted MBSP Ranger Ann Malys-Wilson. His rescuers then contacted the SC Department of Natural Resources for guidance in whether or not to release him and, luckily for the turtle, it was determined that he should be admitted into our Sea Turtle Hospital.
27 May 2015: Socastee’s recovery is progressing smoothly! We are thankful that all involved in his rescue accurately identified that this animal was suffering from a severe illness and chose not to simply release him back into the ocean, as it is likely that his health would have continued to decline and he would have stranded on the beach at some later time. This loggerhead is currently strong enough to swim in a full tank of filtered water, and is consuming about 1.0% of his body weight in healthy salmon and mackerel on a daily basis."
