Nicholas Simpson, Francois Lamontagne, Manu Shankar-Hari
PURPOSE OF REVIEW: We reviewed the recent advances in the initial approach to resuscitation of sepsis and septic shock patients. RECENT FINDINGS: Sepsis and septic shock are life-threatening emergencies. Two key interventions in the first hour include timely antibiotic therapy and resuscitation. Before any laboratory results, the need for resuscitation is considered if a patient with suspected infection has low blood pressure (BP) or impaired peripheral circulation found at clinical examination...

Mathieu Jozwiak, François Depret, Jean-Louis Teboul, Jean-Emmanuel Alphonsine, Christopher Lai, Christian Richard, Xavier Monnet
OBJECTIVES: First, we aimed at assessing whether fluid responsiveness is predicted by the effects of an end-expiratory occlusion on the velocity-time integral of the left ventricular outflow tract. Second, we investigated whether adding the effects of an end-inspiratory occlusion and of an end-expiratory occlusion on velocity-time integral can predict fluid responsiveness with similar reliability than end-expiratory occlusion alone but with a higher threshold, which might be more compatible with the precision of echocardiography...

Cardiogenic shock is a high-acuity, potentially complex, and hemodynamically diverse state of end-organ hypoperfusion that is frequently associated with multisystem organ failure. Despite improving survival in recent years, patient morbidity and mortality remain high, and there are few evidence-based therapeutic interventions known to clearly improve patient outcomes. This scientific statement on cardiogenic shock summarizes the epidemiology, pathophysiology, causes, and outcomes of cardiogenic shock; reviews contemporary best medical, surgical, mechanical circulatory support, and palliative care practices; advocates for the development of regionalized systems of care; and outlines future research priorities...

Michael E Kiyatkin, Jan Bakker
PURPOSE OF REVIEW: A discussion of recent research exploring the feasibility of perfusion-guided resuscitation of acute circulatory failure with a focus on lactate and microcirculation. RECENT FINDINGS: Upon diagnosis of shock, hyperlactemia is associated with poor outcome and, under appropriate clinical circumstances, may reflect inadequate tissue perfusion. Persistent hyperlactemia despite resuscitation is even more strongly correlated with morbidity and mortality...

Ramon P Clement, Jaap J Vos, Thomas W L Scheeren
PURPOSE OF REVIEW: Haemodynamic monitoring is a cornerstone in the diagnosis and evaluation of treatment in critically ill patients in circulatory distress. The interest in using minimally invasive cardiac output monitors is growing. The purpose of this review is to discuss the currently available devices to provide an overview of their validation studies in order to answer the question whether these devices are ready for implementation in clinical practice. RECENT FINDINGS: Current evidence shows that minimally invasive cardiac output monitoring devices are not yet interchangeable with (trans)pulmonary thermodilution in measuring cardiac output...

Bernd Saugel, Jean-Louis Vincent, Julia Y Wagner
PURPOSE OF REVIEW: To describe personalized hemodynamic management of critically ill patients in the operating room and the ICU. RECENT FINDINGS: Several recent clinical studies have investigated different strategies for optimizing blood pressure (BP) and flow in the operating room and in the ICU. In the past, (early) goal-directed hemodynamic treatment strategies often used predefined fixed population-based 'normal' values as hemodynamic targets. Most hemodynamic variables, however, have large interindividual variability and are dependent on several biometric factors...

Geert Koster, Iwan C C van der Horst
PURPOSE OF REVIEW: The objective was to define the role of ultrasound in the diagnosis and the management of circulatory shock by critical appraisal of the literature. RECENT FINDINGS: Assessment of any patient's hemodynamic profile based on clinical examination can be sufficient in several cases, but many times unclarities remain. Arterial catheters and central venous lines are commonly used in critically ill patients for practical reasons, and offer an opportunity for advanced hemodynamic monitoring...

Azriel Perel
PURPOSE OF REVIEW: To discuss the physiological significance and clinical value of dynamic preload variables in spontaneously breathing patients. RECENT FINDINGS: Dynamic preload variables reflect the response of the cardiac output to a modification of preload and can therefore be used to assess fluid responsiveness. Continuous dynamic parameters that are calculated from the variations in the arterial and plethysmographic waveforms following a mechanical breath have been shown to predict fluid responsiveness much better than static preload parameters...

Tyler Lewis, Cristian Merchan, Diana Altshuler, John Papadopoulos
Vasopressors are an integral component of the management of septic shock and are traditionally given via a central venous catheter (CVC) due to the risk of tissue injury and necrosis if extravasated. However, the need for a CVC for the management of septic shock has been questioned, and the risk of extravasation and incidence of severe injury when vasopressors are given via a peripheral venous line (PVL) remains poorly defined. We performed a retrospective chart review of 202 patients who received vasopressors through a PVL...

Hyperlactatemia is a strong predictor of mortality in diverse populations of critically ill patients. In this article, we will give an overview of how lactate is used in the intensive care unit. We describe the use of lactate as a predictor of outcome, as a marker to initiate therapy and to monitor adequacy of initiated treatments.

OBJECTIVE: Dynamic tests of fluid responsiveness have been developed and investigated in clinical trials of goal-directed therapy. The impact of this approach on clinically relevant outcomes is unknown. We performed a systematic review and meta-analysis to evaluate whether fluid therapy guided by dynamic assessment of fluid responsiveness compared with standard care improves clinically relevant outcomes in adults admitted to the ICU. DATA SOURCES: Randomized controlled trials from MEDLINE, EMBASE, CENTRAL, clinicaltrials...

#13
Olfa Hamzaoui, Thomas W L Scheeren, Jean-Louis Teboul
PURPOSE OF REVIEW: Norepinephrine is the first-line agent recommended during resuscitation of septic shock to correct hypotension due to depressed vascular tone. Important clinical issues are the best timing to start norepinephrine, the optimal blood pressure target, and the best therapeutic options to face refractory hypotension when high doses of norepinephrine are required to reach the target. RECENT FINDINGS: Recent literature has reported benefits of early administration of norepinephrine because of the following reasons: profound and durable hypotension is an independent factor of increased mortality, early administration of norepinephrine increases cardiac output, improves microcirculation and avoids fluid overload...

Right ventricular (RV) failure remains a major cause of global morbidity and mortality for patients with advanced heart failure, pulmonary hypertension, or acute myocardial infarction and after major cardiac surgery. Over the past 2 decades, percutaneously delivered acute mechanical circulatory support pumps specifically designed to support RV failure have been introduced into clinical practice. RV acute mechanical circulatory support now represents an important step in the management of RV failure and provides an opportunity to rapidly stabilize patients with cardiogenic shock involving the RV...

Fluid management is a complex subject in healthcare, particularly when pertaining to critically ill patients. Following a literature search on international recommendations regarding fluid administration for shocked patients, an audit was undertaken at Rotorua Public Hospital, New Zealand, to assess how the local fluid resuscitation strategy could be improved. The first part of the audit looked at the fluid resuscitation approach used to treat shocked patients admitted to the ICU of Rotorua Hospital in 2014 and changes required to achieve best practice recommendations...

Shock is a life-threatening state commonly encountered by the acute physician. As such those practicing and training in the specialty should strive to become true experts in this field by going beyond even the learning provided by generic life support courses when involved with identifying and managing the shocked state. This article explores the current evidence, where it exists and provides a framework for approaching such patients along with common pitfalls.

Radu Postelnicu, Laura Evans
PURPOSE OF REVIEW: Monitoring of mental status and peripheral circulatory changes can be accomplished noninvasively in patients in the ICU. Emphasis on physical examination in conditions such as sepsis have gained increased attention as these evaluations can often serve as a surrogate marker for short-term treatment efficacy of therapeutic interventions. Sepsis associated encephalopathy and mental status changes correlate with worse prognosis in patients. Evaluation of peripheral circulation has been shown to be a convenient, easily accessible, and accurate marker for prognosis in patients with septic shock...

Jaume Mesquida, Guillem Gruartmoner, Ricard Ferrer
PURPOSE OF REVIEW: To evaluate the existing evidence on the passive leg raising (PLR) test for fluid responsiveness prediction. RECENT FINDINGS: It has been well established that either insufficient or excessive fluid administration derives in worse outcomes in critically ill patients, highlighting that a more accurate assessment of fluid management is required. Accordingly, several cardiovascular indices have been tested to improve our ability to predict patients' response to fluid loading at the bedside, the so-called functional hemodynamic monitoring...

James Simmons, Corey E Ventetuolo
PURPOSE OF REVIEW: We will briefly review the classification of shock and the hallmark features of each subtype. Available modalities for monitoring shock patients will be discussed, along with evidence supporting the use, common pitfalls, and practical considerations of each method. RECENT FINDINGS: As older, invasive monitoring methods such as the pulmonary artery catheter have fallen out of favor, newer technologies for cardiac output estimation, echocardiography, and noninvasive tests such as passive leg raising have gained popularity...

Background: During fluid challenge, volume expansion (VE)-induced increase in cardiac output (Δ VE CO) is seldom measured. Methods: In patients with shock undergoing strictly controlled mechanical ventilation and receiving VE, we assessed minimally invasive surrogates for Δ VE CO (by transthoracic echocardiography): fluid-induced increases in end-tidal carbon dioxide (Δ VE E'CO2 ); pulse (Δ VE PP), systolic (Δ VE SBP), and mean systemic blood pressure (Δ VE MBP); and femoral artery Doppler flow (Δ VE FemFlow)...
