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. In the ACLS pulseless arrest algorithm, vasopressin may replace the first or second dose of epinephrine. Therefore, terlipressin in a single 1-mg dose is an optional treatment for intraoperative hypotension refractory to catecholamines, especially in patients using renin–angiotensin system inhibitors.67,68Terlipressin (fig. 1and table 2) is a synthetic vasopressin analog that is administered intravenously and converted into lysine vasopressin, resulting in a vasopressor effect lasting Very low doses of vasopressin (from 0.01 to 0.05 units/min) have been shown to improve mean arterial pressure. In addition, doses above 0.04 units/minute did not consistently improve hemodynamics.

Vasopressin local infiltration is useful in gynecological surgery because it can reduce hemorrhage. Depending on the activities of the sympathetic system and the renin–angiotensin system, reactions Doses of vasopressin sufficient for an antidiuretic effect are not likely to produce tonic uterine contractions that could be deleterious to the fetus or threaten the continuation of the pregnancy. Nursing Mothers. Caution should be exercised when Pitressin is administered to a nursing woman. Indications, dose, contra-indications, side-effects, interactions, cautions, warnings and other safety information for VASOPRESSIN. A 2-U bolus dose was used to treat anaphylactic shock.5As in this case, two 0.4-U boluses successfully treated hypotension secondary to both bowel retraction in patients having abdominal aortic resection repair and postreperfusion syndrome during liver transplantation.6,7Terlipressin (a vasopressin precursor) in doses of 1 or 2 mg successfully treated hypotension secondary to induction of 2020-02-21 Background Vasopressin is commonly used as an adjunct to catecholamines to support blood pressure in refractory septic shock, but its effect on mortality is unknown. We hypothesized that low-dose v 2018-11-16 Low doses of vasopressin and terlipressin can restore vasomotor tone in conditions that are resistant to catecholamines, with preservation of renal blood flow and urine output.

May give enema prior to first dose of vasopressin; Dosing Modifications. Hepatic impairment: Lower doses may be required to achieve response; Gastrointestinal Hemorrhage (Off-label) Adult: 0.2-0.4 unit/minute intravenously (IV) initially; may be increased to 0.8 unit/minute IV as needed; Pediatric: 0.3 units/kg IV; not to exceed 20 units Results: A total of 182 patients were included in the analysis, with 136 in the standard-dose vasopressin group and 46 in the high-dose vasopressin group.

Diabetes Insipidus. 2.5-10 units IM/SC/intranasally q8-12hr.

Vasopressin administered at 0.01-0.1 U/min has an apparent t 1/2 of ≤10 minutes, 10 although half-lives of up to 44 minutes have been reported in the literature. Clearance Administration of a low-dose vasopressin infusion (0.04 U/min) significantly increased arterial blood pressure in these patients and permitted the withdrawal of other catecholamine agents. 11,12 Furthermore, a dose of exogenous vasopressin that provided a plasma concentration expected for the degree of hypotension resulted in a marked pressor response. Low-Dose Vasopressin and Analogues to Treat Intraoperative Refractory Hypotension in Patients Prescribed Angiotensin-Converting Enzyme Inhibitors Undergoing General Anesthesia: A Systematic Review Kara F. Hedman, DNP, CRNA Carrie L. Mann, DNP, CRNA Cheryl Spulecki, DNAP, MS, RN, CRNA In IHCA in particular, vasopressin may be used in a lower 20-IU dose with epinephrine and methylprednisolone followed by hydrocortisone, which is suggested in the updated AHA ACLS guidelines.

Table 2 Recommended vasopressin and terlipressin doses used in clinical practice and research studies Indication Dose Vasopressin Terlipressin Cardiac arrest 0.4 U/kg IV per dose43 10–20 µg/kg per dose Shock 0.0005–0.002 U/kg/min (0.5–2 mU/kg/minor 0.03–0.12 U/kg/h) 10–20 µg/kg Q4–12h; 10–20 µg/kg/h 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. Push-dose epinephrine and phenylephrine are the agents used most frequently in this scenario. The majority of a dose of vasopressin is metabolized and rapidly destroyed in the liver and kidneys. Vasopressin has a plasma half-life of about 10 to 20 minutes.

Vasopressin has a plasma half-life of about 10 to 20 minutes.

Abdominal Roentgenography. 10 units (0.5mL) IM/SC 2 hours before procedure, then 10 units IM 30 minutes 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.[54898] However, low dose vasopressin (0.5 to 2 milliunits/kg/minute continuous IV infusion) showed no clinical benefit … 2013-12-17 Vasopressin augments the response to catecholamine therapy, reducing the required catecholamine dose, 3,4 and may be a more effective vasopressor in patients with severe acidosis, when the efficacy of adrenergic agents is potentially reduced due to receptor down-regulation. 5 Onset of action: 1–2 minutes. 6 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. 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 Mechanism Dose Clinical Pearls Vasopressin receptor agonist 0.03 units/minute - Often unnecessary in COVID patients, as they do not require high doses of norepinephrine - May be preferred in patients with atrial arrhythmias or pulmonary hypertension Third Line Vasopressor: Epinephrine Mechanism Dose Clinical Pearls α1 agonist (strong), β1 2019-01-12 Maximum dose: 0.07 units/minute.
