Catéter de arteria pulmonar en shock cardiogénico: novedades acerca de su valor pronóstico y marcadores derivados

Rev. chil. cardiol; 42 (1), 2023
El uso del catéter de arteria pulmonar es un método eficaz para la monitorización de los pacientes críticos. Aunque ampliamente utilizado en las Unidades de Cuidados Críticos Cardiológicos, no se ha demostrado en estudios previos el beneficio de su uso. Registros recientes y numerosos en pacientes ...

Agreement analysis of stroke volume and cardiac output measurement between a oscillometric device and transthoracic echocardiogram in normotensive individuals: a preliminary report

Braz. J. Anesth. (Impr.); 73 (4), 2023
Abstract Introduction The evaluation of stroke volume (SV) is useful in research and patient care. To accomplish this, an ideal device should be noninvasive, continuous, reliable, and reproducible. The Mobil-O-Graph (MOG) is a noninvasive oscillometric matrix validated for measuring aortic and periphera...

Comparative study between suprasternal and apical windows: a user-friendly cardiac output measurement for the anesthesiologist

Braz. J. Anesth. (Impr.); 73 (4), 2023
Abstract Introduction Transthoracic echocardiography is a safe and readily available tool for noninvasive monitoring of Cardiac Output (CO). The use of the suprasternal window situated at the sternal notch can be an alternative approach for estimating blood flow. The present study aimed to compare two m...

RESUMEN Objetivo: Comparar las medidas de gasto cardiaco por ecocardiografía transtorácica y por catéter arterial pulmonar en pacientes en ventilación mecánica con presión positiva al final de la espiración elevada. Evaluar el efecto de la insuficiencia tricúspide. Métodos: Se estudiaron 16 pa...

Test-Retest Reliability of Non-Invasive Cardiac Output Measurement during Exercise in Healthy Volunteers in Daily Clinical Routine

Arq. bras. cardiol; 113 (2), 2019
Abstract Background: Thoracic bioreactance (TB), a noninvasive method for the measurement of cardiac output (CO), shows good test-retest reliability in healthy adults examined under research and resting conditions. Objective: In this study, we evaluate the test-retest reliability of CO and cardiac po...

La posición de Trendelenburg no cambia el gasto cardíaco en voluntarios sanos

Rev. chil. anest; 48 (2), 2019
BACKGROUND: The Trendelenburg position (TP) has been empirically used to increase preload and thus cardiac output (CO). Transthoracic echocardiogram (TTE) is a noninvasive technique that estimates CO. We aimed to describe if the TP can improve CO. MATERIALS AND METHODS: We conducted a descriptive study i...

Uso de ecocardiografia junto ao leito para medir índices cardíaco e de resistência vascular sistêmica em pacientes pediátricos com choque séptico

RESUMO Objetivo: Acompanhar o índice cardíaco e o índice de resistência vascular sistêmica até a ressuscitação. Métodos: Por meio de ecocardiografia junto ao leito, obteve-se um conjunto de parâmetros hemodinâmicos, inclusive débito cardíaco, volume sistólico, índice cardíaco, índice d...

Disminución de la presión venosa central: efecto sobre el gasto cardíaco

Rev. chil. cir; 69 (4), 2017
Introducción: La disminución de la presión venosa central (PVC) a menos de 5mmHg ha sido recomendada para disminuir el sangrado durante la cirugía hepática. No se conoce el efecto de esto en el llenado ventricular e índice cardíaco (IC). Objetivo: Medir el efecto en el volumen de fin de diástole ...
