Microcirculation is the motor of sepsis. In the present study, we investigated whether microcirculatory alterations occur prior to changes of systemic hemodynamics in a rat model of cecum ligation and puncture (CLP)-induced sepsis. We further investigated renal microcirculatory changes during sepsis and compared those with buccal microcirculation. Twelve male Sprague-Dawley rats were randomized into a sham control group (n = 6) and a CLP group (n = 6). Perfused microvessel density (PVD) and microvascular flow index (MFI) were evaluated using sidestream dark field (SDF) video microscopy at baseline, 60, 120, 180, 240, 300, and 360 minutes following CLP...

BACKGROUND: Excessive adrenergic signaling may be harmful in sepsis. Using β-blockers to reduce sympathetic overactivity may modulate sepsis-induced cardiovascular, metabolic, immunologic, and coagulation alterations. Using a randomized ovine fecal peritonitis model, we investigated whether administration of a short-acting β-blocker, esmolol, could control tachycardia without deleterious effects on hemodynamics, renal perfusion, cerebral perfusion, cerebral metabolism, or outcome. METHODS: After induction of fecal peritonitis, 14 anesthetized, mechanically ventilated, and hemodynamically monitored adult female sheep were randomly assigned to receive a continuous intravenous infusion of esmolol to control heart rate between 80 and 100 bpm (n = 7) or a saline infusion (control group, n = 7)...

REVIEW

Rates of heart failure hospitalization remain unacceptably high. Such hospitalizations are associated with substantial patient, caregiver, and economic costs. Randomized controlled trials of noninvasive telemedical systems have failed to demonstrate reduced rates of hospitalization. The failure of these technologies may be due to the limitations of the signals measured. Intracardiac and pulmonary artery pressure-guided management has become a focus of hospitalization reduction in heart failure. Early studies using implantable hemodynamic monitors demonstrated the potential of pressure-based heart failure management, whereas subsequent studies confirmed the clinical utility of this approach...

Cardiopulmonary resuscitation has a low success rate both in and out of the hospital setting. Return of spontaneous circulation, however, is considerably higher for intraoperative cardiac arrests. Chest compressions remain of utmost importance. Optimal chest compression depth is believed to be greater than 5 cm. However, this depth is often not achieved. We describe a case in which the adequacy of chest compressions, based on hemodynamic monitoring, was achieved with 2 persons simultaneously providing a compressive force...

Far from traditional "vital signs," the field of hemodynamic monitoring is developing rapidly. However, it is also easy to misunderstand hemodynamic therapy as merely hemodynamic monitoring and some concrete bundles or guidelines for circulation support. Here, we describe the concept of "critical hemodynamic therapy (CHT)" and clarify the concepts of the "therapeutic target" and "therapeutic endpoint" in clinical practice.Three main targets (Oxygen Delivery - Blood Flow - Perfusion Pressure, OFP) for resuscitation are reviewed in critically ill patients according to the sepsis guidelines and hemodynamic consensus...

EDITORIAL
Abhishek Gupta, Sundeep Mishra
Role of hemodynamic monitoring in critically ill patients is still controversial. While invasive monitoring is accurate, it may be counter-productive in view of its essentially invasive nature. Non-invasive monitoring is less intrusive but has not yet been well validated for accuracy compared with gold standard of invasive monitoring.

BACKGROUND: Laryngeal electromyography (LEMG) is accepted as safe, with minimal side effects. However, patient hemodynamic stability, during these procedures, has not been reported. This study aimed to investigate the hemodynamics in patients undergoing LEMG and determine the risk factors for hemodynamic changes. METHODS: We recruited 89 consecutive patients who underwent LEMG. Baseline and postprocedural changes in vital signs were analyzed. RESULTS: Diastolic blood pressure (DBP) increased from 75...

With the rapid development of critical care medicine (CCM) in China, there are increases in the number of intensive care units (ICUs), the scale of one center ICU and the team. Subspecialty construction of CCM is of great concerns for personnel training as well as discipline development, and is currently one of the urgent problems that need to be resolved. Experience of CCM subspecialty construction from Europe and the United States is lacking and it is necessary to propose some opinions on innovation to construct CCM subspecialties with Chinese characteristics...

BACKGROUND: The quantification of B-lines at lung ultrasonography is a valid tool to estimate the extravascular lung water (EVLW) in patients after major cardiac surgery. However, there is still uncertainty about the correlation between B-lines and EVLW in a general population of critically ill. AIM: To evaluate a simplified lung ultrasonographic assessment as a tool to estimate the EVLW in critically ill patients admitted to a polyvalent intensive care unit (ICU)...

Clinical applications that require extraction and interpretation of physiological signals or waveforms are susceptible to corruption by noise or artifacts. Real-time hemodynamic monitoring systems are important for clinicians to assess the hemodynamic stability of surgical or intensive care patients by interpreting hemodynamic parameters generated by an analysis of aortic blood pressure (ABP) waveform measurements. Since hemodynamic parameter estimation algorithms often detect events and features from measured ABP waveforms to generate hemodynamic parameters, noise and artifacts integrated into ABP waveforms can severely distort the interpretation of hemodynamic parameters by hemodynamic algorithms...

Cardiogenic shock (CS) represents an advanced state of morbidity along the pathophysiologic pathway of end-organ hypoperfusion caused by reduced cardiac output and blood pressure. Acute coronary syndromes remain the most common cause of CS. The spectrum of hypoperfusion states caused by low cardiac output ranges from pre-CS to refractory CS and can be characterized by an array of hemodynamic parameters. This review provides the foundation for a hemodynamic understanding of CS including the use of hemodynamic monitoring for diagnosis and treatment, the cardiac and vascular determinants of CS, and a hemodynamic approach to risk stratification and management of CS...

Trans-ulnar access is a viable alternative approach by experienced operators when the radial and femoral arteries cannot be accessed or used to preserve the contralateral radial artery as possible vascular graft for coronary bypass surgery, hemodynamic monitoring, or shunt creation for hemodialysis. We report a challenging case of ipsilateral trans-ulnar recanalization of a chronic radial artery occlusion, which allowed us to perform a complex trans-ulnar PCI.

The effect of hemodynamic optimization in critically ill patients has been challenged in recent years. The aim of the meta-analysis was to evaluate if a protocolized intervention based on the result of hemodynamic monitoring reduces mortality in critically ill patients. We performed a systematic review and meta-analysis according to the Cochrane Handbook for Systematic Reviews of Interventions. The study was registered in the PROSPERO database (CRD42015019539). Randomized controlled trials published in English, reporting studies on adult patients treated in an intensive care unit, emergency department or equivalent level of care were included...

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...
