Abstract

Primary uterine inertia is the inherent inability of the uterus to contract and expel a fully grown foetus after the end of the gestation period, through a normal birth canal, in the absence of obstructive dystocia.There are conflicting reports regarding the blood parameters in parturient animals,and animals with dystocia and its role in uterine inertia are not well documented. Haematology analysis was performed in dogs with Complete Primary Uterine Inertia (CPUI, n=9) and Partial Primary Uterine Inertia (PPUI, n=6), as well as control animals with the Foetal Cause of Dystocia (FCD, n=7).Blood samples were collected from the study population and total leucocyte count (TLC), total erythrocyte count (TEC), differential leucocyte count (DLC), erythrocytic indices, haemoglobin and haematocrit values were estimated in an autoanalyzer. Haematology analysis revealed no significant difference between the groups. Differential leucocyte counts exhibited lymphocytosis across the groups suggestive of the active immune response related to CL lysis,a characteristic associated with the termination of the pregnancy in canines. Erythrocyte count, haemoglobin concentration and haematocrit revealed anaemia across the group.The study characterised the haematology profile of prepartum canines, which indicated anaemia associated with haemodilution and lymphocytosis associated with active immune status. It also proved that the haematology profile doesnot have any significant role in the pathogenesis of canine uterine inertia.
