BACKGROUND: We conducted this study to investigate whether norepinephrine increases cardiac contractility when administered during the early phase of septic shock. METHODS: We studied 38 patients with septic shock who had been resuscitated for <3 h and whose mean arterial pressure (MAP) remained <65 mm Hg. Echocardiographic variables were obtained before (T 0 ) and after either initiation or an increase in the dose of a norepinephrine infusion to increase MAP to ≥ 65 mm Hg (T 1 )...

Expiratory flow limitation (EFL) is present when the flow cannot rise despite an increase of the expiratory driving pressure. The mechanisms of EFL are debated but are thought to be related to the collapsibility of small airways. In mechanically ventilated patients, EFL can exist during tidal ventilation, representing an extreme situation where lung volume cannot decrease whatever the expiratory driving forces. It is a key factor for the generation of auto- or intrinsic positive end-expiratory pressure (auto-PEEP or PEEPi) and requires specific management such as positioning and adjustment of external PEEP...

REVIEW
C Boer, S M Bossers, N J Koning
The consensus that i.v. resuscitation fluids should be considered as drugs with specific dose recommendations, contraindications, and side-effects has led to an increased attention for the choice of fluid during perioperative care. In particular, the debate concerning possible adverse effects of unbalanced fluids and hydroxyethyl starches resulted in a re-evaluation of the roles of different fluid types in the perioperative setting. This review provides a concise overview of the current knowledge regarding the efficacy and safety of distinct fluid types for perioperative use...

Refractory shock is a lethal manifestation of cardiovascular failure defined by an inadequate hemodynamic response to high doses of vasopressor medications. Approximately 7% of critically ill patients will develop refractory shock, with short-term mortality exceeding 50%. Refractory vasodilatory shock develops from uncontrolled vasodilation and vascular hyporesponsiveness to endogenous vasoconstrictors, causing failure of physiologic vasoregulatory mechanisms. Standard approaches to the initial management of shock include fluid resuscitation and initiation of norepinephrine...

OBJECTIVES: Cardiogenic shock constitutes the final common pathway of cardiac dysfunction associated with tissue hypoperfusion and organ failure. Besides treatment of the underlying cause, temporary mechanical circulatory support serves as a supportive measure. Extracorporeal membrane oxygenation can effectively prevent hypoxemia and end-organ dysfunction, but knowledge about patient selection, risks, and complications remains sparse. DATA SOURCES: Clinical observation...

Pleural effusion (PLEFF), mostly caused by volume overload, congestive heart failure, and pleuropulmonary infection, is a common condition in critical care patients. Thoracic ultrasound (TUS) helps clinicians not only to visualize pleural effusion, but also to distinguish between the different types. Furthermore, TUS is essential during thoracentesis and chest tube drainage as it increases safety and decreases life-threatening complications. It is crucial not only during needle or tube drainage insertion, but also to monitor the volume of the drained PLEFF...

BACKGROUND: Circulatory shock is a common syndrome with a high mortality and limited therapeutic options. Despite its discovery and use in clinical and experimental settings more than a half-century ago, angiotensin II (Ang II) has only been recently evaluated as a vasopressor in distributive shock. We examined existing literature for associations between Ang II and the resolution of circulatory shock. METHODS: We searched PubMed, MEDLINE, Ovid, and Embase to identify all English literature accounts of intravenous Ang II in humans for the treatment of shock (systolic blood pressure [SBP] ≤ 90 mmHg or a mean arterial pressure [MAP] ≤ 65 mmHg), and hand-searched the references of extracted papers for further studies meeting inclusion criteria...

Atrial fibrillation (AF) and stroke are important major health problems that share common risk factors and frequently coexist. Left atrial (LA) remodeling is an important underlying substrate for AF and stroke. LA dilation and dysfunction form a prothrombotic milieu characterized by blood stasis and endothelial dysfunction. In addition, alterations of the atrial cardiomyocytes, increase of noncollagen deposits in the interstitial space and fibrosis, favor the occurrence of re-entry that predisposes to AF. Eventually, AF further impairs LA function and promotes LA remodeling, closing a self-perpetuating vicious circle...

REVIEW

Transcatheter aortic valve replacement has become an accepted alternative to surgery for patients with severe, symptomatic aortic stenosis who are inoperable or are at high surgical risk. Recent trials support the use of transcatheter aortic valve replacement also in patients at intermediate risk, and ongoing trials are assessing appropriateness in other patient groups. The authors review the key anatomic features integral to the transcatheter aortic valve replacement procedure and the echocardiographic imaging required for preprocedural, intraprocedural, and postprocedural assessment...

Coagulation management, and transfusion practice in liver transplantation (LT) have been evolving in the recent years due to better understanding of coagulation abnormalities in end-stage liver disease, and clinical management of LT patients. Avoidance of allogeneic blood components is feasible in some patients, but multi-modal coagulation therapies may be necessary in others who develop complex coagulopathy due to hemorrhage, hemodilution, hypothermia, and acid-base disturbances. Transfusions of plasma and cryoprecipitate remain to be the mainstay therapy for procoagulant factor replacement during LT...

REVIEW
James M East, Christine Cserti- Gazdewich, John T Granton
Heparin induced thrombocytopenia (HIT) is associated with significant morbidity and mortality. Critically ill patients are commonly thrombocytopenic and exposed to heparin. Although HIT should be considered, it is not usually the cause of thrombocytopenia in the medical-surgical ICU population. A systematic approach to the critically ill patient with thrombocytopenia using clinical features, complemented by appropriate laboratory confirmation should lead to a reduction in inappropriate laboratory testing and reduce the use of more expensive and less reliable anticoagulants...

REVIEW

Carcinoid tumors are neuroendocrine tumors with a very unpredictable clinical behavior. In the setting of hepatic metastases, the tumor's release of bioactive substances into the systemic circulation results in carcinoid syndrome: a constellation of symptoms among which cutaneous flushing, gastrointestinal hypermotility, and cardiac involvement are the most prominent. Cardiac manifestations, also known as carcinoid heart disease, are secondary to a severe fibrotic reaction which frequently involves the right-sided valves and may extend towards the subvalvular apparatus leading to valve thickening and retraction...

Pulmonary hypertension (PH) is defined by a mean pulmonary artery pressure ≥ 25 mmHg, as determined by right heart catheterization. Pulmonary arterial hypertension (PAH) can no longer be considered an orphan disease given the increase in awareness and availability of new drugs. PH carries with it a dismal prognosis and leads to significant morbidity and mortality. Symptoms can range from dyspnea, fatigue and chest pain to right ventricular failure and death. PH is divided into five groups by the World Health Organization (WHO), based on etiology...

With the advent of "wireless" endocardial pacing, the subcutaneous implantable cardioverter defibrillator, and leadless pacemakers comes an added layer of complexity to the perioperative management of cardiovascular implantable electronic devices (CIED). Since no formal recommendations currently exist for these new CIED technologies, preoperative identification of these devices, understanding their functionality, and developing an individualized perioperative management plan are imperative for the anesthesiologist...
