vasopressin infusion dose

in further hemodynamic improvements. In the ACLS pulseless arrest algorithm, vasopressin may replace the first or second dose of epinephrine. Vasopressin Injection should be given IM at three or four hour intervals as needed. Doses of vasopressin ranged from 0.04 to 4.8 units/ hour, however most doses ABSTRACT Central Diabetes Insipidus (CDI) is a common complication of Traumatic Brain Injury (TBI). Background: Peri-intubation cardiac arrest and hypotension in patients with septic shock occur often in the emergency department (ED) and ultimately lead to worse clinical outcomes. In a retrospective review of high versus conventional vasopressin doses showed no additional benefit from doses greater than 0.08 units/min. One option for CDI management is a Continuous Vasopressin Infusion (CVI). Vasopressin tends to decrease heart rate and cardiac output. The dosage should be proportionately reduced for pediatric patients. In recent years, the use of push-dose, or bolus-dose, vasopressors in the ED have become common practice for transient hypotension and bridging to continuous infusion vasopressors. Dosage of 2.5–10 units 2–4 times daily has been given. b 0.1 to 8 milliunits/kg/minute continuous IV infusion; this dosage range is not well established, based on several case series/reports and retrospective reviews demonstrating increased arterial blood pressure and urine output as well as decreased catecholamine requirements in pediatric shock. Six patients experienced cardiac arrest during vasopressin infusion. b. Pediatric Patients Diabetes Insipidus† IM or Sub-Q. Potency of vasopressin is standardized according to pressor activity in rats and is expressed in USP posterior pituitary (pressor) units. 170. Median vasopressin dosing was 0.5 Units/hour. The pressor effect is proportional to the infusion rate of exogenous vasopressin. In addition, doses above 0.04 units/minute did not consistently improve hemodynamics. Studies of vasopressin in adults with vasodilatory shock have used infusion rates of 0.01 to 0.1 units/min. Usually has been given in proportionately reduced dosage (from adult dosage). When determining the dose of Vasopressin Injection for a given case, the following should be kept in mind: (Class III) Tsuneyoshi and colleagues performed a prospective study to determine the cardiovascular and metabolic effects of low-dose vasopressin (5). Dose range is 0.1 to 1.2 mg divided into 2 or 3 doses. (For an additional discussion of dosage, consult the sections below.) Dosage. IV: 1 to 2 mcg twice a day Subcutaneously: 1 to 2 mcg twice a day Use in children requires careful fluid intake restrictions to prevent possible hyponatremia and water intoxication. 40 units of vasopressin IV/IO push may be given to replace the first or second dose of epinephrine, and at this time, there is insufficient evidence for recommendation of a specific dose per the endotracheal tube. The dose may be 2trated to between 0.01units/minute (1.5mL/hour) and 0.04units/ minute (6mL/hour)Doses higher than 0.04units/minute are reserved for salvage therapy and must be discussed with In patients with vasodilatory shock vasopressin in therapeutic doses increases systemic vascular resistance and mean arterial blood pressure and reduces the dose requirements for norepinephrine. Ongoing infusion of vasopressin despite evidence of malperfused digits. Dose A low dose vasopressin infusion of 0.03units/minute (4.5mL/hour of the 0.4units/mL solu2on) is recommended by the Surviving Sepsis Guidelines. Vasopressin dose should be used only as a supplementary vasopressor to these agents at a continuous low-dose infusion (0.04 U/min) and should not be titrated as a single agent. Four were receiving doses >0.05 units/minute.
