Role of vasopressin in septic shock : Critical evaluation.

[Role of vasopressin in septic shock : Critical evaluation.] Anaesthesist. 2014 May 18; Authors: Gradwohl-Matis I, Brunauer A, Dankl D, Dünser M Abstract Restoration of adequate tissue perfusion is the goal of resuscitation in septic shock. A growing understanding of microcirculatory dysfunction in sepsis led to a change in resuscitation practice away from targeting arterial and central venous pressures and towards tissue perfusion-guided protocols. This change in the approach to resuscitation was accompanied by a change in the role of vasoconstrictors. This review summarizes the pathophysiological and therapeutic mainstays of septic shock resuscitation and attempts to critically evaluate the scientific evidence on the use of vasopressin as a non-adrenergic vasoconstrictor in septic shock. Based on the published study results vasopressin appears to be of potential benefit in adult patients with moderate septic shock (norepinephrine requirements

Conclusion The impact of sepsis on the gut is manifold, e.g., sepsis mediated alteration of the gut-blood barrier and increase in the intestinal permeability, which may correlate with the phenomena of bacterial translocation and lymphatic activation (“toxic-lymph”). Systemic consequences of sepsis are widespread and concern to the coagulative system, the microbiome as well as enzymes, such as pancreatic proteases, MMPs and IAPs. Nevertheless, the therapeutic approaches for modulating the mucosal immune system are still rarely effective in daily routine. Recent published studies showing that treatment with FMT,...

Background: Noninvasive evaluation of muscle perfusion using near-infrared spectroscopy (NIRS) coupled with a vascular occlusion test (VOT) may provide an early and simple marker of altered perfusion and microcirculatory function in sepsis. Objective: The aim of the study was to compare the time-course of NIRS-derived variables with systemic measures of perfusion in an experimental model of peritonitis. Methods: Peritonitis was induced in eight anesthetized, mechanically ventilated, adult sheep (24–34 kg), by injecting autologous feces into the peritoneal cavity. Animals were followed until death or for a max...

We appreciate the comments from Dr. Jha. According to the study protocol, all patients received a cardiac output monitor aiming to optimize fluid status and cardiac index. Therefore, as our data show, with norepinephrine or vasopressin, we did not observe either a reduction in the cardiac index or a worsening of tissue perfusion and oxygenation parameters as lactate and central venous oxygen saturation.1 Furthermore, the incidence of low cardiac output and cardiogenic shock in the norepinephrine and vasopressin groups was not different. We attribute this to the fact that we assessed the fluid status and used inotropes regu...

Conclusions There is a moderate correlation between SvO2 and SvcO2; however, the concordance between them is inadequate. It was not possible to demonstrate that the presence of hypoperfusion alters the concordance between SvO2 and SvcO2. The use of SvO2 instead of SvcO2 may lead to changes in clinical management in a small but clinically relevant portion of patients.

LOW-CARDIAC-OUTPUT SYNDROME (LCOS) commonly is encountered after heart, heart-lung, and lung transplantation. Several reasons can be ascribed to LCOS after thoracic organ transplantation, namely suboptimal donor, poor donor management, poor organ preservation, prolong ischemia time, high baseline pulmonary artery pressure in the recipient, old age, comorbid illnesses, and long cardiopulmonary bypass time.1 –6 LCOS prolongs the postoperative recovery, requires higher doses of inotropes, and compromises end-organ perfusion.

Publication date: December 2016 Source:Best Practice & Research Clinical Anaesthesiology, Volume 30, Issue 4 Author(s): Jan Bakker In this review, the relationship between changes in macrohemodynamics during the development and treatment of acute circulatory failure is discussed in the context of coherence with microcirculation and changes in lactate. In models of circulatory failure, coherence between changes in macrocirculatory and microcirculatory perfusion and coherence with subsequent changes in lactate levels are more or less preserved. However, in patients, particularly those with septic shock, these relationsh...

(Abstracted from Br J Anaesth, 116:339–349, 2016) The current standard of care for managing patients with severe sepsis and septic shock is aggressive fluid resuscitation, until a central venous pressure of greater than 8 mm Hg is achieved. The rationale behind this approach is to increase a patient’s stroke volume, which in turn improves cardiac output and organ perfusion.

In conclusion, in an ovine model of septic shock, administration of HTL was associated with earlier onset impaired tissue perfusion and shorter survival time. These observations raise concerns about use of HTL in septic shock.
