1. The aim of the present study was to determine the effect of water restriction and/or hypoxia on the vasopressin response to haemorrhage in conscious rats.2. Male, Long‐Evans rats (n= 39) were prepared with chronically indwelling femoral artery and vein catheters and exposed to 24 h of one of the following: normoxia withad libdrinking water (N + W); normoxia with water restriction (N – W); hypoxia withad libdrinking water (H + W); and hypoxia with water restriction (H – W). At the end of 24 h, a 15 mL/kg arterial haemorrhage was performed.3. Water restricted rats had elevated pre‐haemorrhage vasopressin levels. Haemorrhage induced an increase in vasopressin in all groups. Water restriction (N – W) or hypoxia (H + W) each augmented the vasopressin response to haemorrhage. However, the combination of hypoxia and water restriction (H – W) failed to augment the vasopressin response to haemorrhage as compared to normoxic, water replete (N + W) rats.4. Hypoxia or water restrictionper seaugment the vasopressin response to haemorrhage. This augmented vasopressin response to haemorrhage is not maintained when hypoxia and water restriction are combined.
