Abstract
Abstract Lesions associated with storage of red blood cells (RBC) in different anticoagulants have been well described in mammals, but not in reptiles to date. The objectives of this study were to document biochemical changes of American alligator (Alligator mississippiensis) packed RBC stored in citrate–phosphate–dextrose–adenine (CPDA-1) and acid–citrate–dextrose (ACD) anticoagulants over the course of 35 days and to describe qualitative and quantitative morphologic changes over 295 days. Blood samples were collected via the occipital sinus from 6 captive-born American alligators of mixed sex (1 male, 5 females). Spun packed cell volume (PCV), total solids, and blood lead levels were analyzed with the use of heparinized blood on Day 0. Samples in CPDA-1 and ACD were stored at 4°C (39.2°F) and the following parameters serially evaluated at varying time points until Day 35: blood culture, blood gas analysis, PCV, methemoglobin, osmotic fragility, and morphologic evaluation by light and transmission electr...
