Systemic vasoplegia is common in patients undergoing liver transplantation. In this report, we present a case in which treatment with conventional vasopressors caused peripheral arterial spasm, rendering arterial blood pressure monitoring impossible. Administration of methylene blue resolved the vasospasm; however, concern for toxic dose requirements limited its use. Hydroxocobalamin administration resolved the vasospasm and increased blood pressure without the potential adverse effects seen with methylene blue...

BACKGROUND: Septic shock has a 90-day mortality risk of up to 50 %. The hemodynamic targets, including mean arterial pressure (MAP) are not based on robust clinical data. Both severe hypotension and high doses of vasopressors may be harmful. Hence, re-evaluation of hemodynamic targets in septic shock is relevant. METHODS/DESIGN: The targeted tissue perfusion versus macrocirculation-guided standard care in patients with septic shock (TARTARE-2S) trial is a prospective, two-parallel-group, randomized, open-label, multicenter trial with assessor-blinded outcome evaluation...

BACKGROUND: Measuring non-invasive blood pressure (NIBP) in less than one minute intervals (STAT NIBP measurements) is not always feasible. Therefore, large number of undetectable hypotension episodes can only be recognized with continuous beat to beat monitoring of blood pressure, for example, by continuous non-invasive arterial pressure monitor (CNAP). OBJECTIVE: The purpose of the current study was to investigate whether CNAP correlates well with conventional intermittent oscillometric NIBP during elective cesarean sections under subarachnoid blockade (SAB) and whether CNAP based patient management results in improved immediate maternal vasopressor requirements and improved immediate fetal/neonatal outcomes compared with NIBP based patient management...

Raynaud syndrome (RS) manifests as episodes of transient spasms of peripheral blood vessels, most often in response to cold. The reason of that symptom (primary RS (pRS)) usually cannot be found but may be accompanied by some autoimmune diseases (secondary RS (sRS)). In this study, we assessed microcapillary status and serum concentrations of chosen cytokines, adhesive molecules, and nitric oxide (NO) in patients with pRS and sRS in comparison with healthy children. Eighty-six patients with RS were enrolled into the study, including 52 with pRS and 34 with sRS...

Prostaglandin E2 (PGE2), a cyclooxygenase metabolite that generally acts as a systemic vasodepressor, has been shown to have vasopressor effects under certain physiologic conditions. Previous studies have demonstrated that PGE2 receptor signaling modulates angiotensin II (Ang II)-induced hypertension, but the interaction of these two systems in the regulation of vascular reactivity is incompletely characterized. We hypothesized that Ang II, a principal effector of the renin-angiotensin-aldosterone system, potentiates PGE2-mediated vasoconstriction...

BACKGROUND: Indications for intra-osseous (IO) infusion are increasing in adults requiring administration of fluids and medications during initial resuscitation. However, this route is rarely used nowadays due to a lack of knowledge and training. We reviewed the current evidence for its use in adults requiring resuscitative procedures, the contraindications of the technique, and modalities for catheter implementation and skill acquisition. METHODS: A PubMed search for all articles published up to December 2015 was performed by using the terms "Intra-osseous" AND "Adult"...

PURPOSE OF REVIEW: Tissue monitoring is one of the main strategies at the bedside to guide resuscitation of shock. Advances in tissue monitoring technologies have established noninvasive optical methods and transcutaneous oximetry as modalities of considerable value in the critical care setting for tissue monitoring in shock. The purpose of this article is to highlight the latest developments into the clinical applications of near-infrared spectroscopy, direct visualization of sublingual microcirculation, and transcutaneous oxygen measurements (PtcO2)...

UNLABELLED: Cardiac arrest (CA) results in a sepsis-like syndrome with activation of the innate immune system and increased mitochondrial bioenergetics. OBJECTIVE: To determine if platelet mitochondrial respiration increases following CA in a porcine pediatric model of asphyxia-associated ventricular fibrillation (VF) CA, and if this readily obtained biomarker is associated with decreased brain mitochondrial respiration. CA protocol: 7 min of asphyxia, followed by VF, protocolized titration of compression depth to systolic blood pressure of 90 mmHg and vasopressor administration to a coronary perfusion pressure greater than 20 mmHg...

Epileptic seizures are often accompanied by increased sympathetic cardiovascular activity (even interictally), but it remains unknown whether this increased activity is of central and/or peripheral origin. Hence, this study investigated the cardiovascular alterations produced by amygdala kindling in awake and pithed Wistar rats. Blood pressure (BP) and heart rate (HR) were initially recorded by tail cuff plethysmography in awake control, sham-operated and amygdala-kindled rats before and 24 hr after the kindling process...

Management of cardiovascular instability resulting from calcium channel antagonist (CCB) or beta-adrenergic receptor antagonist (BB) poisoning follows similar principles. Significant myocardial depression, bradycardia and hypotension result in both cases. CCBs can also produce vasodilatory shock. Additionally, CCBs, such as verapamil and diltiazem, are commonly ingested in sustained-release formulations. This can also be the case for some BBs. Peak toxicity can be delayed by several hours. Provision of early gastrointestinal decontamination with activated charcoal and whole-bowel irrigation might mitigate this...

Dopamine is commonly used as a first-line agent in the treatment of patients with septic shock. The use of dopamine rarely causes symmetric peripheral dry gangrene. If the symmetric peripheral dry gangrene occurs in the patient after dopamine injection, it easily leads to disagreement between doctors and patients. A 60-year-old woman who had sudden septic shock was sent to intensive care unit (ICU). She was received dopamine injection according to the routine during treatment. Over the next 3 months, her limbs developed to dry gangrene and required amputation...
