Twenty four buffalo- cows suffering from uterine torsion and 10 normally calving buffaloes were used in the present work. Both arterial and venous blood was collected from the auricular artery and jugular vein, respectively. The blood samples were collected just before parturition and 15 hours later in normal parturient buffaloes, as well as immediately before and 15 hours after manipulation of uterine torsion in affected animals. The changes in plasma progesterone concentration, erythrocyte osmotic fragility, acid base status and blood gas tension were determined. The obtained results revealed a direct tightly relationship between the degree of moisture of the vagina and prognosis of torsion, where rolling of torsion affected buffaloes was indicated only in cases with high moisture of the vagina. The placenta of torsion affected buffaloes dropped rapidly than in normal parturient females. Moreover, the plasma progesterone content was significantly elevated in buffalo-cows suffered from uterine torsion with closed cervix before treatment than that recorded after injection of prostaglandin F2α and dexamethasone or estradiol benzoate and then that observed in females suffered from uterine torsion with open cervix and those with normal parturition. There was an initial haemolysis in higher saline strength and maximum haemolysis in lesser saline strength in torsion affected animals as compared to those observed in normal calving buffaloes. Both initial and maximum haemolysis occurred significantly in higher saline strength in buffaloes that died as compared with the survivors females after manipulation of uterine torsion. There was significant increase in arterial hydrogen ion concentration (pHa), partial arterial pressure of oxygen (Pa02), partial arterial pressure of carbon dioxide (PaC02), partial venous pressure of oxygen (Pv02), arterial oxygen saturation (SaO2) and venous oxygen saturation (SvOz) and a decrease in base excess (BE) and actual bicarbonate of plasma (HcO") in died torsion affected animals than that observed in both survivors females after manipulation of uterine torsion and normal parturient ones. Following manipulation of uterine torsion the partial arterial pressure of oxygen (Pa02.) was sharply dropped in survivors’ animals and unchanged in died females. It could be concluded that the rolling of torsion affected buffaloes was preferable in cases with high moisture of the vagina. Injection of estradiol benzoate is indicated in females with closed cervix after rolling. Determination of the erythrocyte osmotic fragility, acid base status and blood gas tension improved the chance of survival of dam and her fetus with injection of some drugs that strength the erythrocyte membrane and an adequate fluid and electrolyte therapy. |
