With a national shortage of octreotide an alternative treatment plan had to be implemented at our institution for patients presenting with variceal bleeding.
Drug references recommend a continuous infusion of vasopressin at 0.2 to 0.4 units/minute. Dose may be titrated as needed to a maximum dose of 0.8 units/minute with maximum duration of 24 hours to reduce incidence of adverse effects. Administer IV nitroglycerin concurrently to prevent ischemic complications and monitor closely for signs/symptoms of myocardial, peripheral, and bowel ischemia.
Protocol at our institution:
Initiate vasopressin at 0.2 units/min.
Increase by 0.2 units/min if bleeding is not controlled after one hour (max dose: 0.8 units/min).
If bleeding controlled for 2 hours, can decrease by 0.2 units/min and reassess.
Limit use to 24 hours.
Use nitroglycerin infusion to prevent adverse effects from vasopressin.
Initiate nitroglycerin at 40 mcg/min, titrate by 40 mcg/min to a max dose of 400 mcg/min.
Goal systolic blood press pressure of 90-100 mmHg. Do not start nitroglycerin if SBP <90 mmHg.
***Please note the vasopressin dose for this indication is significantly higher than the typical dose of 0.03 units/min we use for shock.***
