Tissue expansion-related severe complication exists, and the poor blood supply is one of the causes. After decades of negative correlation between capsule pressure and blood flow was verified, the widely recognized expansion capsule pressure is still absent. A prospective randomized controlled trial was performed to explore the optimal expanding capsule pressure. Thirty subjects were randomly divided into 5 groups, received a weekly expanding on 60-, 70-, 80-, 90-, and 100-mm Hg capsule pressure, respectively...

Volume resuscitation of patients with high-voltage electrical injuries (>1000 V) is a more complex challenge than standard burn resuscitation. High voltages penetrate deep tissues. These deep injuries are not accounted for in resuscitation formulae dependent on percentage of cutaneous burn. Myonecrosis occurring from direct electrical injury and secondary compartment syndromes can result in rhabdomyolysis, compromising renal function and urine output. Urine output is the primary end point, with a goal of 1 mL/kg/h for adult patients with high-voltage electrical injuries...

PURPOSE OF REVIEW: Heart failure is a growing epidemic. Optimal medical therapy remains the cornerstone of heart failure management but device-based therapies have been shown to contribute to morbidity and mortality reduction. RECENT FINDINGS: Multiple investigational trials had been conducted in the past decade that helped us better understand and manage heart failure. In this manuscript, we will discuss the major device related trials of year 2017 in the fields of defibrillators, hemodynamic monitoring, remote monitoring, autonomic nervous system modulation, ventricular assist devices, and device-based valvular heart disease management...

BACKGROUND/PURPOSE: Hemoglobin monitoring is required in pediatric trauma patients with solid organ injury. We hypothesized that noninvasive hemodynamic monitoring (NIHM) represents an effective, safe alternative to laboratory hemoglobin (LabHb) monitoring in clinically stable patients. METHODS: A retrospective cohort study was conducted regarding pediatric trauma patients (<18 years old) with blunt solid organ injury over six consecutive months. Continuous NIHM was initiated at the time of admission, and LabHb measurements were obtained per institutional guidelines...

"Perioperative goal-directed therapy" (PGDT) aims at an optimization of basic and advanced global hemodynamic variables to maintain adequate oxygen delivery to the end-organs. PGDT protocols help to titrate fluids, vasopressors, or inotropes to hemodynamic target values. There is considerable evidence that PGDT can improve patient outcome in high-risk patients if both fluids and inotropes are administered to target hemodynamic variables reflecting blood flow. Despite this evidence, PGDT strategies aiming at an optimization of blood flow seem to be not well implemented in routine clinical care...

BACKGROUND: Determining volume responsiveness in critically ill patients is challenging. We sought to determine if passive leg raise (PLR) induced changes in pulsed wave Doppler of the carotid artery flow time could predict fluid responsiveness in critically ill patients. MATERIALS AND METHODS: Medical intensive care unit patients ≥18 years old with a radial arterial line and FloTrac/Vigileo monitor in place were enrolled. Pulsed wave Doppler of the carotid artery was performed to measure the change in carotid flow time (CFTC) in response to a PLR...

Near-infrared spectroscopy (NIRS) has become widely accepted as a valuable tool for noninvasively monitoring hemodynamics for clinical and diagnostic purposes. Baseline shift has attracted great attention in the field, but there has been little quantitative study on baseline removal. Here, we aimed to study the baseline characteristics of an in-house-built portable medical NIRS device over a long time (>3.5 h). We found that the measured baselines all formed perfect polynomial functions on phantom tests mimicking human bodies, which were identified by recent NIRS studies...

Hemodynamic monitoring is essential during the treatment of the critically ill in order to address the hemodynamic alterations and assess the response to treatment. Traditionally classified causes of shock and underlying pathophysiological mechanisms are often neglected by resuscitative strategies included in the guidelines. Most of hemodynamic management focuses on the ability to early recognise patients susceptible to increase cardiac output (CO) and mean arterial pressure (MAP) after a defined fluid challenge by eliciting Starling's law of the heart, and less is known of the ones presenting in shock and not volume responsive...

BACKGROUND: Standard insufflators compensate for intra-abdominal pressure variations with pressure spikes. Our aim was to evaluate the impact of a stable, low-pressure pneumoperitoneum induced by a valve-less insufflator, on working space, hemodynamics, inflammation, and peritoneal physiology, in a model of laparoscopic sigmoid resection. MATERIALS AND METHODS: Twelve pigs (47 ± 3.3 kg) were equipped for invasive hemodynamic monitoring and randomly assigned to Standard (n = 6) vs...

Pregnancy in women with systemic lupus erythematosus (SLE)-associated pulmonary arterial hypertension (PAH) remains a high risk. We successfully managed a pregnancy in a patient with SLE-PAH. A 31-year-old pregnant woman with SLE-PAH had worsening PAH and SLE flare-up during pregnancy and a sudden increase in pulmonary arterial pressure after delivery. SLE-PAH was controlled by continuous intravenous epoprostenol and inhaled nitric oxide therapy combined with high-dose corticosteroids under close hemodynamic monitoring...

In spite of advances in perioperative management, operative procedures in patients with chronic liver disease pose a significant challenge for the anesthesiologist due to multisystem involvement, high risk of postoperative hepatic decompensation, and mortality. We describe the anesthetic management of an elderly patient with advanced liver disease (model for end-stage liver disease 16) for prolonged abdominal surgery. The use of invasive hemodynamic monitoring, point-of-care biochemical, and hematological surveillance coupled with prompt correction of all abnormalities was responsible for good outcome...

BACKGROUND: Increasing rates of obesity create new challenges for hemodynamic monitoring in the perioperative phase. Continuous monitoring of arterial pressure (AP) is important in severely obese patients who are at particular risk for cardiovascular complications. Innovative technologies for continuous noninvasive AP monitoring are now available. In this study, we aimed to compare continuous noninvasive AP measurements using the vascular unloading technique (CNAP system; CNSystems, Graz, Austria) compared with invasive AP measurements (radial arterial catheter) in severely obese patients during laparoscopic bariatric surgery...

The measurement of arterial pressure (AP) is a key component of hemodynamic monitoring. A variety of different innovative AP monitoring technologies became recently available. The decision to use these technologies must be based on their measurement performance in validation studies. These studies are AP method comparison studies comparing a new method ("test method") with a reference method. In these studies, different comparative statistical tests are used including correlation analysis, Bland-Altman analysis, and trending analysis...

Lee S Nguyen, Pierre Squara
Critically ill patients require close hemodynamic monitoring to titrate treatment on a regular basis. It allows administering fluid with parsimony and adjusting inotropes and vasoactive drugs when necessary. Although invasive monitoring is considered as the reference method, non-invasive monitoring presents the obvious advantage of being associated with fewer complications, at the expanse of accuracy, precision, and step-response change. A great many methods and devices are now used over the world, and this article focuses on several of them, providing with a brief review of related underlying physical principles and validation articles analysis...

Autonomic dysreflexia (AD) is a potentially life-threatening syndrome in individuals with spinal cord injury (SCI) above the T6 spinal level that is characterized by episodic hypertension in response to noxious stimuli below the lesion. Maladaptive intraspinal plasticity is thought to contribute to the temporal development of AD, and experimental approaches that reduce such plasticity mitigate the severity of AD. The mammalian target of rapamycin (mTOR) has gained interest as a mediator of plasticity, regeneration and nociceptor hypersensitivity in the injured spinal cord...
