BACKGROUND: Intraoperative hypotension is associated with postoperative mortality. Early detection of hypotension by continuous hemodynamic monitoring might prompt timely therapy, thereby reducing intraoperative hypotension. We tested the hypothesis that continuous noninvasive blood pressure monitoring reduces intraoperative hypotension. METHODS: Patients ≥45 years old with American Society of Anesthesiologists physical status III or IV having moderate-to-high-risk noncardiac surgery with general anesthesia were included...

Advances in noninvasive hemodynamic monitoring systems allow delivery of goal-directed fluid therapy and could therefore be used in less-invasive surgical procedures. In this randomized controlled trial, we compared closed-loop-assisted goal-directed fluid therapy using a noninvasive cardiac output (Clearsight system) monitor (personalized approach) to a protocolized fluid therapy approach in 40 patients undergoing moderate-risk laparoscopic abdominal surgery. Cardiac output and stroke volume variations were not significantly different in both groups and remained within predefined target values >90% of the study time...

To describe the baseline hemodynamic variables and response time of hemodynamic changes associated with the Valsalva maneuver using noninvasive continuous cardiac output monitoring (Nexfin). Hemodynamic monitoring provides an integral component of advanced clinical care and the ability to monitor response to treatment interventions. The emergence of noninvasive hemodynamic monitoring provides clinicians with an opportunity to monitor and assess patients rapidly with ease of implementation. However, the responsiveness of this method in tracking dynamic changes that occur has not been fully elucidated...

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...

BACKGROUND: Impedance cardiography (ICG) is a noninvasive hemodynamic monitoring tool which can define hypertensive patients' hemodynamic profiles and help to tailor antihypertensive therapy. This study assesses the concordance between ICG-derived indexes used to evaluate left ventricular performance and transthoracic echocardiography (TTE) in hypertensive patients. METHODS: In this IMPEDDANS post-hoc analysis, the ICG-derived indexes are compared with TTE by Bland-Altman method...

The present study furthered the concept of simulation-based medical education by applying a personalized active learning component. We tested this novel approach utilizing a noninvasive hemodynamic monitor with the capability to measure and display in real time numerous hemodynamic parameters in the exercising participant. Changes in medical knowledge concerning physiology were examined with a pre-and posttest. Simply by observation of one's own hemodynamic variables, the understanding of complex physiological concepts was significantly enhanced...

Clinicians managing obstetric patients are dependent on valid hemodynamic measurements to guide care. Heart rate and noninvasive blood pressure guide most current care. New hemodynamic monitors are being used to report research findings and are being investigated by clinicians for their value to supplement standard monitoring. These include arterial pulse contour analysis, Doppler velocimetry, and bioimpedance among others. This chapter serves to present these new devices with a critical review of their advantages and limitations, and most importantly the validity of their measurements...

BACKGROUND: An ideal arterial pressure monitoring system for perioperative care is required to be accurate, noninvasive, continuous, and risk free. Although several continuous noninvasive arterial pressures (CNAP) are determined on the finger, a new wrist CNAP monitoring system was developed. This prospective study was designed as a randomized-controlled trial to assess its validity in comparison with invasive arterial pressure (IAP) monitoring. PATIENTS AND METHODS: Sixty patients undergoing elective surgery under general anesthesia were enrolled...

Tetra-amelia syndrome is a congenital disorder associated with near or complete absence of all 4 limbs. Noninvasive hemodynamic monitoring may be difficult or impossible in such patients. We describe the use of a finger cuff blood pressure system for continuous noninvasive blood pressure monitoring in an infant with near-complete tetra-amelia undergoing laparoscopic gastrostomy tube placement. This case suggests the potential use of such a blood pressure monitoring system for other patients with comparable deformities...

INTRODUCTION: It is estimated that 3-10% of infants are growth restricted. Growth disturbances may have long-term issues. Doppler allows insight into the fetal response to intrauterine stress. OBJECTIVE: The aim of this study was to detect fetal compromise in intrauterine growth-restricted (IUGR) fetuses by means of biophysical profile (BPP) vis-à-vis Doppler velocimetry studies of the fetal umbilical artery, and to find out which of the two is a better and earlier predictor of fetal compromise...

The use of a noninvasive hemodynamic monitor to estimate arterial stiffness, by measurement of pulse transit time (PTT), was demonstrated in microgravity. The monitor's utility for space applications was shown by establishing the correlation between ground-based and microgravity-based measurements. The system consists of a scale-based ballistocardiogram (BCG) and a toe-mounted photoplethysmogram (PPG). PTT was measured from the BCG I-wave to the intersecting tangents of the first trough and maximum first derivative of the PPG waveforms of each subject...

We described our experience in using the new noninvasive hemodynamic monitoring (esCCO), which allowed recording most important parameters of heart capacity. Infusion therapy during laparoscopic operations might be based on dynamic of systolic blood volume. This functional approach can be used for evaluation of heart reaction on bolus fluid load, to optimike volemic status in situations associated with dynamical blood circulation changes. We compared intraoperative infused fluid volumes, calculated by traditional approach and by target approach...

Shuangshen Ningxin capsule (SSNX), a modern Chinese formula, has been used to treat cardiovascular diseases in Eastern Asia. Our study focuses on the autophagy regulation of SSNX against coronary artery injuries. Myocardial infarction model was established in Chinese miniswines (CMS) by coronary artery balloon injury. SSNX was administered to the CMS for 8 weeks with 4 mg/kg or 16 mg/kg. Myocardial cells were incubated with 20% SSNX medicated serum for 2 hours. Assays were performed to detect the effects of SSNX on (i) coronary artery diameter by angiography, (ii) hemodynamics by noninvasive hemodynamic monitoring system, (iii) plaque burden and plaque volume by intravenous ultrasound (iv) coronary artery histology by H&E staining, (v) autophagosome by transmission electron microscopy, (vi) lactate dehydrogenase (LDH) leakage, and (vii) Beclin-1 and LC3-I/II expressions by Western blot...

Perioperative hemodynamic optimization of the high-risk surgical patient is associated with reduced postoperative morbidity and mortality. The hemodynamic parameters to be optimized (using goal-directed algorithms) encompass preload, contractility, afterload, volume responsiveness, and end-organ perfusion. Current hemodynamic monitors facilitate multi-modal monitoring of these macro-hemodynamic targets. This review focuses on the variety of invasive, minimally invasive, and noninvasive hemodynamic monitors available to the clinician...
