Vasopressin was dosed at 0.01 to 0.06 U/min, which is similar to dosing in common clinical practice and to the regimens used in large randomized controlled trials of vasopressin versus norepinephrine in sepsis (Vasopressin and Septic Shock Trial [VASST] and the Vasopressin vs. Norepinephrine as Initial Therapy in Septic Shock [VANISH]). Midway through the trial, the executive committee, unaware of all data and in conference with the data and safety monitoring committee, determined that patients who had undergone randomization but had never received an infusion would not be included in the primary analysis, since their omission would be equally distributed between groups, would be unrelated to treatment assignment, and would not bias outcome ascertainment.18 We increased the total number of patients enrolled to maintain the target sample size after the removal of such patients from the analysis. However, current guidelines do not advise clinicians as to which vasoactive agent to discontinue first once the patient's septic shock begins to resolve.

If the clinical team noted an adverse event that they considered to be related to the study drug, then the study drug was discontinued for at least 8 hours and a serious adverse event was reported. Am J Respir Crit Care Med 2003;168:165-172. The reason you see vasopressin used more with cardiac surgery is due to the bypass pump. For most of these analyses, there was no evidence of a significant interaction between illness severity and vasopressin effect. The vasopressin was infused over a set range of doses, and we did not measure vasopressin levels as a guide to the dose or the duration of infusion. Overall mortality, ICU mortality, and length of stay (LOS) in the ICU were secondary outcomes. Cooper, S. Mehta, J. Argenziano M, Chen JM, Choudhri AF, et al. Circulation 1999;100:Suppl:II-182, 27.

In the Vasopressin and Septic Shock Trial (VAAST), patients with septic shock were randomised to receive blinded vasopressin or norepinephrine. Rhodes A, Evans LE, Alhazzani W, Levy MM, Antonelli M, Ferrer R, Kumar A, Sevransky JE, Sprung CL, Nunnally ME, et al. However, the observed mortality rates in both the vasopressin and norepinephrine groups were considerably lower than those in previous studies, perhaps because of overall improvements in the care of patients who have septic shock. Argenziano M, Chen JM, Cullinane S, et al. Robertson, J.F. In VASST, vasopressin was not associated with a reduction in 28-day mortality (35.4%) compared with norepinephrine (39.3%; P = 0.26). There was a trend toward a higher rate of cardiac arrest in the norepinephrine group than in the vasopressin group (2.1% vs. 0.8%, P=0.14) and a trend toward a higher rate of digital ischemia in the vasopressin group than in the norepinephrine group (2.0% vs. 0.5%, P=0.11).

Our selection of a low dose of vasopressin (0.03 U per minute) and careful exclusion of patients who had acute coronary syndromes or severe heart failure could account for the lack of adverse cardiovascular effects of vasopressin infusion. Serious Adverse Events in Patients Who Had Septic Shock. Despite the small statistical difference found with multivariate analysis, there was no clinically significant difference between patients who had norepinephrine discontinued first and patients who had vasopressin discontinued first. Cheng L, Yan J, Han S, Chen Q, Chen M, Jiang H, Lu J. Crit Care. However, in the a priori stratum of less severe shock (defined as 5–15 μg/min of norepinephrine at baseline), there was a significantly lower 28-day mortality in the vasopressin group compared with the norepinephrine group (26.5% vs 35.7%, respectively, P = .05). Clipboard, Search History, and several other advanced features are temporarily unavailable. The study trial was performed at the Heart Institute, Faculty of Medicine, University of Sao Paulo, Sao Paulo, Brazil. Norepinephrine acts mostly on alpha receptors, although it does stimulate beta receptors to a certain degree. In addition, one patient was lost to follow-up before day 28.

Previous studies raised the possibility that vasopressin infusion may increase the incidence of cardiac arrest.29 In contrast, we found that of 11 cardiac arrests reported in this study, 8 occurred in the norepinephrine group and 3 occurred in the vasopressin group. Compared with discontinuing VP first, the incidence of hypotension was significantly lower when NE was discontinued first (odds ratio, OR 0.3, 95% confidence interval, CI 0.10 to 0.86, P = 0.02; I = 91%).

Alternative vasopressor for patients with septic shock who: (1) develop tachyarrhythmias on norepinephrine, epinephrine, or dopamine, (2) have persistent shock despite use of two or more vasopressor/inotropic agents including vasopressin (salvage therapy), or (3) high cardiac output with persistent hypotension. 6; The VANISH study compared norepinephrine vs early vasopressin and the impact on kidney failure in septic shock. Arginine vasopressin in 316 patients with advanced vasodilatory shock. Ischemic skin lesions as a complication of continuous vasopressin infusion in catecholamine-resistant vasodilatory shock: incidence and risk factors. These levels did not change in the norepinephrine group. Comparisons are norepinephrine vs. vasopressin. Low-dose vasopressin did not reduce mortality rates as compared with norepinephrine among patients with septic shock who were treated with catecholamine vasopressors. Crit Care Med 1985;13:818-829, 20. The vasopressin arm utilized less renal replacement therapy, but did not reduce the incidence of kidney failure. Musallam N, Altshuler D, Merchan C, Zakhary B, Aberle C, Papadopoulos J. Ann Pharmacother. 2018 Aug;52(8):733-739. doi: 10.1177/1060028018765187. The article was written by the writing committee, and the decision to publish was made by the executive committee. We calculated that 776 patients were required for enrollment, randomization, and receipt of the study drug in order to detect an absolute 10% difference in mortality, assuming a mortality rate of 60% in the norepinephrine group and a two-sided alpha error of 0.05 and a power of 80%. Norepinephrine Vs epinephrine: Epinephrine has a wider range of effects. Argenziano M, Choudhri AF, Oz MC, Rose EA, Smith CR, Landry DW. Thus 779 patients underwent randomization and infusion of the study drug, and 778 were included in the final primary analysis: 396 in the vasopressin group and 382 in the norepinephrine group (Figure 1). Crit Care Med 1992;20:864-874, 16. Two of the interaction analyses (stratification according to quartile of lactate level and according to number of vasopressors at baseline) yielded moderately significant P values (P=0.04 for both), suggesting a possible advantage of vasopressin in patients with less severe shock, Case Records of the Massachusetts General Hospital, Delayed Large Local Reactions to mRNA-1273 Vaccine against SARS-CoV-2, Choices in a Crisis — Individual Preferences among SARS-CoV-2 Vaccines, Tocilizumab in Patients Hospitalized with Covid-19 Pneumonia, Vaccination plus Decarceration — Stopping Covid-19 in Jails and Prisons, An Uncertain Public — Encouraging Acceptance of Covid-19 Vaccines, Open Schools, Covid-19, and Child and Teacher Morbidity in Sweden, Baricitinib plus Remdesivir for Hospitalized Adults with Covid-19, A Randomized Trial of Albumin Infusions in Hospitalized Patients with Cirrhosis. The difference in the mean infusion rates of the study drug between treatment groups during the first 5 days was within 2 ml per hour. The Vasopressin vs. Norepinephrine as Initial Therapy in Septic Shock (VANISH) randomized controlled trial of vasopressin vs. norepinephrine used a higher dose and applied vasopressin earlier in septic shock but found no difference in acute kidney injury (the primary endpoint) or mortality but did observe a reduction in the use of renal replacement therapy in vasopressin-treated patients. Singer, D.J. Vasopressin selectively constricts the efferent arteriole of the glomerulus, which should improve the glomerular filtration rate (2). Norepinephrine has traditionally been the vasopressor of choice in the treatment of septic shock, recommended as the first-line vasopressor in the Surviving Sepsis Guidelines [].However, vasopressin infusion has been used to replace norepinephrine to maintain adequate systemic arterial pressure (e.g., in patients refractory to norepinephrine) [2,3,4]. To address these uncertainties, we conducted a multicenter, randomized, stratified, double-blind trial among patients who had septic shock and were receiving usual care (including catecholamines), to determine whether vasopressin decreased 28-day mortality, as compared with norepinephrine. All vasopressor infusions were titrated and tapered according to protocols to maintain a target blood pressure. Background: The optimal adjuvant vasopressor to norepinephrine in septic shock remains controversial.Objective: To compare durations of shock-free survival between adjuvant vasopressin and epinephrine.Methods: A retrospective, single-center, matched cohort study of adults with septic shock refractory to norepinephrine was conducted. Hébert, T. McArdle, I. Watpool; University Health NetworkToronto General & Toronto Western Hospitals — J.T. Our secondary hypothesis was that the beneficial effects of vasopressin would be more pronounced than those of norepinephrine in the subgroup of patients with more severe (as opposed to less severe) septi… Interestingly, within the Vasopressin in Septic Shock Trial (VASST) trial, it was found that vasopressin administration was beneficial for patients categorized with less severe septic shock and significantly reduced mortality when compared with only norepinephrine (26.5% vs 35.7%; p = 0.05) ( 11 ). 3 in the Supplementary Appendix). Vasopressin (30 U) and norepinephrine (15 mg) were mixed in identical 250-ml intravenous bags of 5% dextrose in water, with final concentrations of 0.12 U of vasopressin per milliliter and 60 μg of norepinephrine per milliliter. Arginine vasopressin in the management of vasodilatory hypotension after cardiac transplantation. During the initiation and titration of the study drug, the bedside nurse also titrated open-label vasopressors to maintain a constant target mean arterial pressure. Moreover, there is controversial data guiding clinicians on how to discontinue vasopressors for septic shock patients who are receiving a combination therapy of NE and VP. Accessibility Although norepinephrine and epinephrine are structurally related, they have differing effects. The vast majority of us use vasopressin as an adjunct to norepinephrine when we take care of patients who are in septic shock. Bauer SR, Aloi JJ, Ahrens CL, Yeh JY, Culver DA, Reddy AJ. 3. The Vasopressin Versus Norepinephrine After Cardiac Surgery (VANCS) trial was yet another attempt to assess whether vasopressin had a place as a first-line vasopressor. Russell (chair), K.R. Valuable tools for building a rewarding career in health care. Written informed consent was obtained from all patients, their next of kin, or another surrogate decision maker, as appropriate. Cooper, S. Mehta, J. Methods: Trial design and participants Inodilators are agents with inotropic effects that also cause vasodilation leading to decreased systemic and/or pulmonary vascular resistance (SVR, PVR) — e.g. Knaus WA, Draper EA, Wagner DP, Zimmerman JE.

Holmes, J.T. Hébert, D.J. An O'Brien–Fleming approach was used for sequential stopping rules for safety and efficacy according to the Lan–DeMets method.17 After both interim analyses, the data and safety monitoring committee recommended that the study be continued without protocol modification. In the prospectively defined stratum of less severe septic shock, the mortality rate was lower in the vasopressin group than in the norepinephrine group at 28 days (26.5% vs. 35.7%, P=0.05); in the stratum of more severe septic shock, there was no significant difference in 28-day mortality (44.0% and 42.5%, respectively; P=0.76). The study-drug infusion was discontinued or interrupted if any of the following predetermined serious adverse events occurred: acute ST-segment elevation confirmed by a 12-lead electrocardiogram, serious or life-threatening (hemodynamically unstable) cardiac arrhythmias, acute mesenteric ischemia, digital ischemia, or hyponatremia (serum sodium level, <130 mmol per liter).

Norepinephrine group shown. However, the test for the interaction between the treatment assignment and the severity-of-shock subgroup was not significant (P=0.10). An initial target mean arterial pressure of 65 to 75 mm Hg was recommended; however, the attending ICU physician could modify the target blood pressure of each patient. Hayes MA, Yau EH, Hinds CJ, Watson JD. News Rumours Warnings Events Workshops Media Podcasts Forms Studies were limited to adult patients with septic shock who received concomitant NE and VP treatment, that included different orders of vasopressor discontinuation. This trial was conducted between July 2001 and April 2006 in 27 centers in Canada, Australia, and the United States and was approved by the research ethics boards of all participating institutions. 1. They were known as alchemists. Analysis was conducted with the use of SAS software (version 9.1.3), and all P values were two-sided. Tapering of open-label vasopressors was permitted only when the target mean arterial pressure had been reached during the study-drug infusion. Abstract Background: Patients with septic shock in whom norepinephrine (NE) infusion alone is insufficient to raise blood pressure require the concomitant administration of vasopressin (VP). Infusions of both study drugs were prepared locally by study pharmacists who were aware of the two treatments. 2020 Oct 31;8(1):83. doi: 10.1186/s40560-020-00500-0. Granton, M. Steinberg, A.

The primary analysis, which compared 28-day mortality between the two treatment groups, was performed with the use of an unadjusted chi-square test, and all patients were assessed according to the treatment received and to the treatment group assigned at randomization. We hypothesized that low-dose vasopressin as compared with norepinephrine would decrease mortality among patients with septic shock who were being treated with conventional (catecholamine) vasopressors.

Background: Age, illness severity (score on the Acute Physiology and Chronic Health Evaluation [APACHE II] at baseline), serious coexisting conditions, and other baseline covariates that predicted outcome (at a threshold P value of 0.20) were entered into the model. A Comparison for Initial Monotherapy with Norepinephrine Versus Vasopressin for Resuscitation in Septic Shock. Our study was prospectively powered to detect an absolute difference in mortality of 10% from an expected 60%. The pharmacology of PE and NE is well known and is summarized in Table 1.6–8 PE is now readily accepted as a first-line agent to combat hypotension from both general and spinal anesthesia.4,9 In contrast, NE has been viewed with some trepidation.
