In the absence of contraindications to the use of posterior pituitary hormone, posterior pituitary hormone can also be used for continuous hemostatic treatment by micropumping. Vasodilators are sometimes used, especially in patients with hypertension, such as nitroglycerin, phentolamine, and procaine.
