Cardiovascular monitoring is important to prevent diseases from progressing. The jugular venous pulse (JVP) waveform offers important clinical information about cardiac health, but is not routinely examined due to its invasive catheterisation procedure. Here, we demonstrate for the first time that the JVP can be consistently observed in a non-contact manner using a photoplethysmographic imaging system. The observed jugular waveform was strongly negatively correlated to the arterial waveform (r = -0.73 ± 0...

BACKGROUND: Intraoperative hemorrhage is one of the problems during surgery and, if it happens in a high volume without an immediate action to control, it can be fatal. Nowadays, various injectable solutions are used. The aim of this study was to compare the acid-base and hemodynamic status of the patient using two solutions, Ringer lactate and 1.3% sodium bicarbonate, in half saline solution. MATERIALS AND METHODS: This clinical trial was performed at the Al-Zahra Hospital in 2013 on 66 patients who were randomly selected and put in two studied groups at the onset of hemorrhage...

Few inventions in modern medicine have generated as passionate and extended debate as the pulmonary artery catheter (PAC). Since its introduction in 1970, the PAC remains an indispensable monitor in cardiovascular critical care. Despite attempts to develop less invasive alternatives, the PAC remains unequaled as a single monitoring device capable of measuring physiological derangement in most components of the circulation, in the awake or sedated patient, with real-time feedback on the efficacy of an intervention...

OBJECTIVE: Hyperperfusion syndrome (HPS) following carotid artery stenting (CAS) is a rare but serious complication. HPS is associated with preoperative hemodynamic impairment due to poor collateral flow and intraoperative cerebral ischemia. Filter-type embolic protection devices (EPDs) maintain anterograde carotid flow during CAS and somewhat prevent HPS. Early treatment of patients undergoing CAS and at risk for HPS is essential. Near-infrared spectroscopy (NIRS) allows non-invasive, real-time measurement of frontal lobe regional cerebral O2 saturation (TOI; tissue oxygenation index)...

BACKGROUND: Traditional open corrective surgery for isolated sagittal synostosis entails significant blood loss, transfusion rates, morbidity, and a lengthy hospitalization. Minimally invasive strip craniectomy (MISC) was introduced to avoid the disadvantages of open techniques. OBJECTIVES: The aim of the study was, first, to compare the anesthesia practice in MISC and open extended strip craniectomy (OESC), and, second, to evaluate the incidence of perioperative complications in both surgical procedures...

Critically ill patients are often hemodynamically unstable (or at risk of becoming unstable) owing to hypovolemia, cardiac dysfunction, or alterations of vasomotor function, leading to organ dysfunction, deterioration into multi-organ failure, and eventually death. With hemodynamic monitoring, we aim to guide our medical management so as to prevent or treat organ failure and improve the outcomes of our patients. Therapeutic measures may include fluid resuscitation, vasopressors, or inotropic agents. Both resuscitation and de-resuscitation phases can be guided using hemodynamic monitoring...

Purpose Radial artery pseudoaneurysm is uncommon and mainly associated with radial artery cannulization for cardiac intervention or invasive hemodynamic monitoring. It is rarely seen as a result of intra-arterial recreational drug injection. Methods We present the case of a 35-year-old man with a 12-year history of intravenous drug use and 1-year history of intra-arterial drug use who developed radial artery pseudoaneurysm with a right long finger suppurative flexor tenosynovitis and subsequent acute radial-sided hand ischemia...

Transthoracic echocardiography (TTE) has become one of the most important diagnostic tools in the treatment of critically ill patients. It allows clinicians to recognise potentially reversible life-threatening situations and is also very effective in the monitoring of the fluid status of patients, slowly substituting invasive methods in the intensive care unit. Hemodynamic assessment is based on a few static and dynamic parameters. Dynamic parameters change during the respiratory cycle in mechanical ventilation and the level of this change directly corresponds to fluid responsiveness...

Transesophageal echocardiography (TEE) assessment after MitraClip implantation is limited by unequal orifices and jets, eccentric regurgitation, and the acute change of the annulus geometry. Periprocedural real-time invasive hemodynamic assessment of the mitral valve function requires experience in hemodynamic monitoring interpretation. However, it provides excellent accuracy as it does not take into account the changes of the mitral apparatus geometry and jet direction after MitraClip placement. While we seek to expand indications of Mitraclip to other patient subgroups, we should consider routine ancillary invasive hemodynamic assessment, in order to optimize our understanding, procedural results...

AIM: Most pediatric in-hospital cardiac arrests (IHCAs) occur in ICUs where invasive hemodynamic monitoring is frequently available. Titrating cardiopulmonary resuscitation (CPR) to the hemodynamic response of the individual improves survival in preclinical models of adult cardiac arrest. The objective of this study was to determine if titrating CPR to systolic blood pressure (SBP) and coronary perfusion pressure (CoPP) in a pediatric porcine model of asphyxia-associated ventricular fibrillation (VF) IHCA would improve survival as compared to traditional CPR...

REVIEW
D Leoni, J Rello
The incidence of sepsis is increasing, and the condition is now the leading cause of death in general intensive care units. Our review failed to identify studies of the causes of cardiac arrest among infected patients, even though non-cardiac causes represent 15% of out-of-hospital cardiac arrests and though one-third of events have positive blood cultures. Sudden cardiac arrest is the result of local damage to the heart and of the impact of systemic and pulmonary conditions on cardiac performance, and its danger is underestimated...

BACKGROUND AND OBJECTIVES: The aim of this retrospective study was to analyze differences in the initial hemodynamic assessment and its impact on the treatment in patients aged 80 years or older compared to younger patients during the first 6 h after admission to the medical intensive care unit (ICU). RESULTS: We analyzed 615 consecutive patients admitted to the medical ICU of which 124 (20%) were aged 80 years or more. The older group had a significantly higher acute physiology and chronic health evaluation (APACHE II) score, an overall mortality in the ICU and a presence of pre-existing cardiac disease...

BACKGROUND: Transition from an asymptomatic to symptomatic state in severe aortic stenosis is often difficult to assess. Identification of a morphological sign of increased hemodynamic load may be important in asymptomatic aortic stenosis to identify patients at risk. METHODS AND RESULTS: Thirty-nine patients with asymptomatic severe aortic stenosis (aortic valve area <1 cm(2), peak jet velocity >3.5 m/s) underwent exercise testing with simultaneous invasive hemodynamic monitoring and Doppler echocardiography...

Central venous pressure (CVP) is primarily measured to assess intravascular volume status and heart preload. In clinical practice, the measuring device most commonly used in emergency departments and intensive care units, is an electronic transducer that interconnects a central venous catheter (CVC) with a monitoring system. Non-invasive ventilation (NIV) consists in a breathing support that supplies a positive pressure in airways through a mask or a cask though not using an endotracheal prosthesis. In emergency settings, non-invasive ultrasonography evaluation of CVP, and hence of intravascular volume status entail the measurement by a subxiphoid approach of inferior vena cava diameter and its variations in relation to respiratory activity...

Right ventricular (RV) failure after cardiac surgery is associated with an ominous prognosis. The etiology of RV failure is multifaceted and the ability to recognize RV failure early is paramount in order to initiate timely treatment. The present review focuses on different diagnostic modalities for RV function and discusses the normal versus abnormal findings in RV monitoring after cardiac surgery and the limitations of the applicable diagnostic modalities. There are specific challenges in RV assessment after cardiac surgery due to a loss of longitudinal contraction and a concomitant gain of transverse contraction...

Continuous and non-invasive monitoring of hemodynamic parameters through unobtrusive wearable sensors can potentially aid in early detection of cardiac abnormalities, and provides a viable solution for long-term follow-up of patients with chronic cardiovascular diseases without disrupting the daily life activities. Electrocardiogram (ECG) and siesmocardiogram (SCG) signals can be readily acquired from light-weight electrodes and accelerometers respectively, which can be employed to derive systolic time intervals (STI)...

Ethanol is the only liquid embolization agent which can cure arteriovenous malformation. Complications of ethanol embolization are not rare including local tissue injury, intravascular hemolysis and cardiovascular depression even collapse, etc. This report presented a case of long time cardiovascular depression and intravascular hemolysis secondary to ethanol embolotherapy of right ear. In order to avoid the fatal complications that are associated with ethanol sclerotherapy, anesthesiologists should consider the use of continuously invasive hemodynamic monitoring while surgeons should carefully choose the dose of ethanol...

BACKGROUND: Graft reperfusion poses a critical challenge during liver transplantation and can be associated with hemodynamic instability/postreperfusion syndrome. This is sequel to ischemia-reperfusion injury and normothermic machine preservation (NMP) may affect hemodynamic changes. Herein, we characterize postreperfusion hemodynamics in liver grafts after NMP and traditional cold preservation. MATERIALS AND METHODS: Intraoperative records of patients receiving grafts after NMP (n = 6; NMP group) and cold storage (CS) (n = 12; CS group) were compared...
