“…This is similar to the osmolality documented for both domestic canids and felids (290-310 and 290-330 mOsm/kg, respectively) (Macintire et al, 2005;DiBartolla, 2006). This is slightly less but close to the plasma osmolality of green iguanas (Iguana iguana), 327 ± 3.3 mOsm/L (Fitzsimons and Kaufman, 1976) and 300 mOsm/L (Nevarez, 2009), and more similar to the plasma osmolality of two other desert-dwelling squamates, the Gila monster (Heloderma suspectum) and the desert iguana (Dipsosaurus dorsalis). Reported plasma osmolality for these species are 292 mOsm/kg (range, 284-298 mOsm/kg) (Davis and DeNardo, 2007) and 300 mOsm/L (Nevarez, 2009), respectively.…”

“…spaces (Wellman et al, 2006). In contrast, in reptiles, excluding chelonians, it is documented that approximately 71-75% of the body weight is fluid, with 54% distributed in the intracellular spaces and 17% within the extracellular spaces (Mader and Rudloff, 2006;Nevarez, 2009). Fluid balance between the intracellular and extracellular space is (Mader and Rudloff, 2006;Wellman et al, 2006;Nevarez, 2009).…”

Determination of plasma osmolality is useful for determining proper administration of fluid therapy. In many reptilian species, the normal plasma osmolality is unknown. To prevent detrimental fluid shifts, knowledge of a patient's osmolality is imperative. The purpose of this study was to determine plasma osmolality in 11 healthy adult male bearded dragons (Pogona vitticeps) and to validate plasma osmolality equations that are used to calculate osmolality in other species. Venipuncture was performed via the ventral coccygeal vein, and plasma biochemical profiles were obtained from a point of care chemistry analyzer. Calculated plasma osmolality was determined using the following equations: 2 (Na + + K +), (2 [Na + + K + ]) + (Glu/18), (2 [Na + + K + ]) + (UA/16.8) + (Glu/18), and 1.86 (Na +) + Glu/18 + UA/2.8 + 9. Plasma osmolality was measured in duplicate with a freezing-point depression osmometer, and the mean value was calculated for the two osmolality measurements. Measured and calculated plasma osmolalities, as well as the plasma biochemical analytes, were normally distributed. The mean measured plasma osmolality was 295.4 ± 9.35 mOsm/kg. There was poor agreement between the measured and calculated osmolalities. Because of these limitations, we modified the calculation [1.85 (Na + + K +)] to account for expected differences in the primary cations and anions in reptile plasma. This newly proposed formula resulted in good agreement with the measured osmolality. Osmolality of the bearded dragons in this study was similar to that reported in dogs, cats, and other desert-dwelling saurian lizards. When administering fluids to a dehydrated or debilitated bearded dragon, caution is advised as calculated values are not an accurate measure of patient osmolality.

: Monitoring anaesthesia in reptiles can be daunting for the RVN, but with increasing numbers of reptiles being seen and treated in practice it is more important than ever for the RVN to understand how to monitor anaesthesia safely in these patients. The usual monitoring tools can be used in reptile anaesthesia, but there are some differences when compared with their use in mammals. Such differences are highlighted here, alongside useful practical information of what to expect during the induction, maintenance and recovery phases of anaesthesia, and how best to monitor an anaesthetised reptile throughout each stage.
