Morphological changes in the arterial pressure waveform following hemodynamic therapies in critical care: A clinical proof‐of‐concept study in older adults

Physiological Reports, Volume 14, Issue 15, August 2026.
In 132 cardiac surgery patients, fluid bolus, norepinephrine, and dobutamine each produced a distinct, recognizable pattern in arterial waveform morphology (systolic area/downstroke time, diastolic area/time, augmented pressure), suggesting arterial waveform analysis is a promising tool for bedside hemodynamic decision support.

Hepatosplanchnic perfusion changes following isolated abdominal trauma and surgery: A scoping review of evidence dominated by pneumoperitoneum models

Physiological Reports, Volume 14, Issue 15, August 2026.
Abstract The hepatosplanchnic vascular response to isolated abdominal organ injury remains poorly defined. The aim of this review was to synthesize the available evidence on macrovascular hepatosplanchnic flow and organ‐specific microvascular perfusion following isolated abdominal injury or surgery.

Dobutamine Stress Echocardiography and Tissue Synchronization Imaging

Eurasian Journal of Medicine, 2019
Dobutamine stress echocardiography has emerged as a reliable method for the diagnosis of coronary artery disease and the management of its treatment. Several studies have shown that that this technique works with 80-85% accuracy in comparison with other ...

NiMoO4 nanosheets modified carbon paste electrode for simultaneous determination of epinine and dobutamine

Journal of Electrochemical Science and Engineering
In this work, a carbon paste electrode was modified with ionic liquids and NiMoO4 nanosheets (NMs/IL/CPE) for voltammetric epinine detection. The NMs/IL/CPE showed good electro­catalytic activity for epinine oxidation compared to unmodified CPE.

Impact of bicarbonate on ionized calcium and cardiac function in albumin‐free Langendorff perfusion in hearts of male rats

Physiological Reports, Volume 14, Issue 15, August 2026.
Abstract The adult Langendorff methodology lacks standardization, with inconsistencies in the pH and calcium concentrations of Krebs–Henseleit (K‐H) solution. The aim of this study was to clarify these inconsistencies. Adult male Wistar rat hearts were subjected to 40 or 80 min of global ischemia followed by reperfusion.

Wall motion assessment by feature tracking in pediatric patients with coronary anomalies undergoing dobutamine stress CMR

Frontiers in Cardiovascular Medicine
BackgroundLeft ventricular (LV) wall motion assessment is an important adjunct in addition to perfusion defects in assessing ischemic changes. This study aims to investigate the feasibility and utility of performing feature tracking (FT) in pediatric ...

Uso de dobutamina para la inducción de arritmias durante estimulación eléctrica programada del corazón Dobutamine use for arrythmia induction during electrical programmed heart stimulation

Revista Colombiana de Cardiología, 2006
Introducción: el isoproterenol es el fármaco que se ha empleado tradicionalmente para incrementar la inducción de arritmias cuando durante la estimulación eléctrica programada del corazón en condiciones basales, no se logra su inducción. La dobutamina es

É necessário suspender o betabloqueador na insuficiência cardíaca descompensada com baixo débito? ¿Es necesario suspender el betabloqueante en la insuficiencia cardíaca descompensada con bajo débito? Is it necessary to suspend betablockers in decompensated heart failure with low output?

Arquivos Brasileiros de Cardiologia, 2010
FUNDAMENTO: Há evidências de que a suspensão do betabloqueador (BB) na descompensação cardíaca pode aumentar mortalidade. A dobutamina (dobuta) é o inotrópico mais utilizado na descompensação, no entanto, BB e dobuta atuam no mesmo receptor com ações ...

Dobutamine-induced alterations in internal carotid artery blood flow and cerebral blood flow in healthy adults

Brain Research Bulletin
Purpose: Dobutamine, a sympathomimetic agent, is widely used clinically, influencing cardiac output, heart rate (HR), and blood pressure (BP), which may impact cerebral blood flow (CBF), critical for brain metabolism.

Outpatient Intravenous Dobutamine as Right Ventricular Support During Inhaled Prostacyclin Uptitration in Severe PH‐ILD

Pulmonary Circulation
PH‐ILD carries a poor prognosis, particularly with PVR > 5 WU. The INCREASE trial demonstrated the successful use of inhaled treprostinil, but slow uptitration delays the effects.
