Is there a vasopressin titration protocol for high blood pressure?
There are plenty of vasopressin titration protocols one can look up online and which have also been used in studies to achieve a mean arterial pressure goal. I’ve also bolused vasopressin after coming off cardiopulmonary bypass and in trauma with associated acidosis with very good results.
Is abrupt discontinuation of vasopressin safe in patients recovering from septic shock?
In patients recovering from septic shock, abrupt discontinuation of AVP appears to be safe and may lead to shortened AVP duration. Abrupt Discontinuation Versus Down-Titration of Vasopressin in Patients Recovering from Septic Shock Shock. 2021 Feb 1;55(2):210-214.doi: 10.1097/SHK.0000000000001609. Authors
How many units do you titrate for an IV infusion?
-Initial dose: 0.03 units/min IV infusion -If target blood pressure response is not achieved: titrate up by 0.005 units/min at 10 to 15 minute intervals -Maximum dose: 0.1 units/min
How much taper is needed to maintain target blood pressure?
-After target blood pressure has been maintained for 8 hours without use of catecholamines, taper by 0.005 units/min every hour as tolerated to maintain target blood pressure.

When can I add a second vasopressor?
However, there is a “good” consensus among experts to start a second vasopressor in cases of refractory hypotension (3) to prevent the effects of excessive NE load (strategy of “decatecholaminization”).
When do you start vasopressin in septic shock?
The Surviving Sepsis Campaign (SSC) 2021 proposes to start AVP in septic shock when the dose of norepinephrine (NE) base is in the range of 0.25–0.5 µg/kg/min [2]. Basing the decision on a threshold dose in vasodilatory shock is an easy bedside rule but has some flaws.
What is the maximum infusion rate for vasopressin when used for shock?
Standard maximum rate: 2.4 units/hr (2.4 mL/hr). ICU Consultant maximum rate: 4 units/hr (4 mL/hr). Rates above 2.4 units/hr MUST be authorised by the ICU Consultant. These higher doses may cause severe vasoconstriction resulting in regional ischaemia (including coronary or mesenteric ischaemia).
Why is vasopressin used in ICU?
The rationale for use of vasopressin in the ICU is that there is a vasopressin deficiency in vasodilatory shock and advanced shock from any cause and that exogenously administered vasopressin can restore vascular tone.
Should we start vasopressors very early in septic shock?
Optimal timing for starting vasopressors (VP) in sepsis has not been adequately tested since guidelines recommend fluids to be administered first. Some physiological reasons supported by observational and experimental studies suggest that an early start of vasopressors could be advantageous.
How long can you stay on vasopressors?
Despite widespread use, vasopressors have not been adequately studied with regard to infusion time. In our single-center retrospective analysis, a vasopressor duration of greater than 48 hours was not associated with an increase in mortality.
How do you titrate vasopressin drip?
The infusion is started at 1-4 mcg/min and titrated up for effect. The usual dose is 2-10 mcg/min. It is a very quick-acting drug with an extremely short half-life. It can be titrated up by 1-2 mcg/min every 20 minutes until the desired effect or hemodynamic stability.
How do you infuse vasopressin?
Prepare as follows: Draw 0.5ml of vasopressin 20 units in 1 ml into syringe and make up to 50 ml using sodium chloride 0.9%. Label syringe as per Trust Policy. Start pump at 0.45ml/hour, titrating against patient's haemodynamics state.
How is vasopressin dosed?
May be given as bolus dose of 50 to 100 mcg to support blood pressure during rapid sequence intubation. Must be diluted. The usual concentration is 10 mg in 250 mL D5W or NS (40 mcg/mL).
How often should you titrate vasopressin?
These agents are titrated to clinical endpoints but should not be titrated faster than every 5 to 15 minutes to avoid potentially overshooting hemodynamic targets. In clinical practice, vasopressin is commonly administered as a fixed dose with no bedside nurse titration.
Do you wean vasopressin?
Wean vasopressors in the 'correct' order A recent meta-analysis published in 2020 identified 8 studies comparing weaning vasopressin (VP) versus norepinephrine (NE) first. 7/8 studies found a lower rate of rebound hypotension when NE was weaned first.
When do you give vasopressin?
Vasopressin injection is also used to increase blood pressure in adults with vasodilatory shock (eg, post-cardiotomy, sepsis) who remain to have low blood pressure after receiving fluids and medicines. Vasopressin is a hormone that is produced in the body. It acts on the kidneys to reduce the flow of urine.
