If you must treat a closed-cervix pyometra medically, do so cautiously because of the great risk of the uterus rupturing. It stimulates uterine motility, forcing the uterine contents through the cervix, thus explaining why it is so dangerous to use with a closed-cervix pyometra. Side effects include panting, salivation, vomiting, defecation and micturition. However, these effects usually disappear after the first hour of treatment and subsequent injections result in less severe signs. Prognosis is good for those patients treated with surgery.
Prognosis is poor for patients treated medically for closed-cervix pyometras.
Pyometritis Pearls Pyometritis is a life-threatening emergency and surgery should be performed as soon as possible. Before initiating treatment, ultrasonography should be used to determine if the dog might be pregnant. Before surgery, initiate shock fluids and broad-spectrum, bactericidal antibiotics.
