Emodinamica

Una guida operativa pratica per il clinico in ambiente critico, con l’obiettivo di orientare rapidamente le decisioni terapeutiche abbandonando l’approccio per “tentativi ed errori” a favore di una “early goal directed therapy” basata su dati oggettivi.Punti chiave dell’opera: Approccio Fisiopatologico: Il testo approfondisce la meccanica cardiaca attraverso lo studio del ciclo cardiaco e delle curve pressione/volume (P/V loop). Viene data grande rilevanza alla fase diastolica, spesso trascurata ma fondamentale nei moderni quadri di scompenso, e alla fisiologia del ventricolo destro, definito “The dark side of the moon” per la sua complessità e importanza prognostica. Monitoraggio Integrato: Viene analizzato l’intero spettro del monitoraggio emodinamico, considerando il catetere polmonare (Swan-Ganz) ancora come “gold standard” per i quadri complessi, ma integrando ampiamente tecniche meno invasive (termoldiluizione transpolmonare, analisi del contorno di polso) ed ecocardiografia. Il Metodo “OPLÀ“: Il cuore del manuale è l’algoritmo diagnostico-terapeutico originale OPLÀ, ideato per guidare il rianimatore attraverso quattro priorità sequenziali: Ossigenazione (bilancio DO2/VO2, lattati) Pompa (funzione sistolica) Lunghezza delle fibre (precarico/diastole) Àfterload (postcarico e perfusione). Terapia e Supporto Avanzato: Il volume tratta in dettaglio la terapia farmacologica (inotropi, vasopressori, inodilatatori) e la gestione dei fluidi, estendendosi fino all’assistenza meccanica al circolo (MCS) come Contropulsatore, IMPELLA ed ECMO. Scenari Clinici e Interventistica: Sono presenti sezioni dedicate a quadri specifici come shock (cardiogeno, settico, ostruttivo), valvulopatie e la gestione anestesiologica in cardiologia interventistica (TAVI, MitraClip, Ablazioni). In sintesi, l’opera mira a trasformare i dati numerici del monitoraggio in strategie cliniche immediate, offrendo un metodo razionale per gestire il paziente critico con tempestività.

Edizione italiana sulla terza in lingua inglese a cura di Fabrizio Monaco e Jacopo D’Andria Ursoleo.  Lo studio invasivo dell’emodinamica costituisce le basi della comprensione della fisiologia cardiovascolare negli stati di salute e nei processi patologici. Molte delle conoscenze ad oggi consolidate derivano dal contributo fornito alla disciplina da innumerevoli medici negli ultimi otto decenni, e, nonostante ciò, questo è un campo che rimane in continua espansione, con nuove scoperte e continue migliorie. La valutazione emodinamica è ormai una componente cardine dei protocolli di cateterizzazione cardiaca; tuttavia, questo aspetto è spesso trascurato da molti cardiologi e programmi di formazione in cardiologia, che danno largo spazio, invece, alle tecniche angiografiche e interventistiche o alle metodiche non invasive quali l’ecocardiografia, la tomografia computerizzata cardiaca e la risonanza magnetica. Senza dubbio queste tecniche permettono di studiare minuti dettagli anatomici che in passato non erano acquisibili, ma presentano anche dei limiti riguardo alla loro capacità di valutare l’impatto della patologia cardiaca sulla fisiologia. In aggiunta, è importante eseguire queste valutazioni in modo meticoloso, dal momento che le condizioni dei pazienti sottoposti a valutazione emodinamica possono essere misconosciute o erroneamente diagnosticate per errori di misura o interpretazione. Tuttavia, l’attuale espansione del campo della cardiologia interventistica strutturale ha portato a un rinnovato interesse nell’emodinamica, dal momento che alcuni dei suoi principi e delle pratiche, spesso dimenticati, sono di enorme importanza durante questo tipo di procedure. È quindi indispensabile per un cardiologo astuto maneggiare con dimestichezza i principi dell’emodinamica clinica e della valutazione emodinamica invasiva per poter correttamente eseguire e interpretare i test diagnostici, potendo trattare quindi molte malattie cardiovascolari.Questo libro mira a fornire informazioni sull’emodinamica, a partire dall’analisi delle forme d’onda ottenute nel laboratorio di cateterismo cardiaco. Verranno discussi approfonditamente, con l’ausilio di illustrazioni di numerose forme d’onda emodinamiche derivanti dalla pratica clinica, la normale fisiologia e l’intero spettro degli stati fisiopatologici che si può incontrare nel laboratorio di cateterizzazione cardiaca e nelle unità di terapia intensiva. La terza edizione contiene nuove figure e aggiornamenti di tutte le sezioni e l’aggiunta dei paragrafi riguardanti le valutazioni emodinamiche ecocardiografiche nel contesto della malattia valvolare mitralica, aortica e della cardiomiopatia ipertrofica. Questa edizione, inoltre, dispone di due nuovi capitoli, uno sul monitoraggio al letto del paziente nell’unità di terapia intensiva e uno sulla funzione diastolica del cuore.Quest’opera è concepita per l’utilizzo da parte dei medici specializzandi in cardiologia (inclusi sia coloro che seguono la formazione in cardiologia generale, sia coloro che la seguono in cardiologia interventistica e strutturale), dei cardiologi e dei cardiologi interventisti in preparazione agli esami di certificazione o di rinnovo della certificazione, nonché del personale infermieristico e tecnico di laboratorio di emodinamica. Anche gli infermieri specializzati in cardiologia, i medici assistenti, il personale infermieristico delle unità coronariche, i medici di terapia intensiva e i medici in formazione in medicina interna possono trovare i contenuti di questo testo interessanti e utili per la pratica clinica.

Presentazione di Maurizio Cecconi

Edizione italiana sulla IV in lingua inglese

This book describes how to monitor and optimize cardiovascular dynamics using advanced hemodynamic monitoring in perioperative and intensive care medicine. The book outlines basic skills of hemodynamic monitoring, different techniques including invasive, minimally invasive, and non-invasive methods, and algorithms and treatment strategies for perioperative goal-directed hemodynamic therapy in different groups of surgical patients. Thus, the book reflects current diagnostic and therapeutic approaches in perioperative and intensive care medicine. All sections of this book have a learning-oriented style and are illustrated with tables and figures summarizing the main content. The volume is addressed both to specialists and residents using advanced hemodynamic monitoring; it reflects indications and limitations of current monitoring tools and discuss therapeutic strategies. It also helps readers to integrate new knowledge on monitoring of cardiovascular dynamics into clinical practice.

This book, part of the European Society of Intensive Care Medicine textbook series, teaches readers how to use hemodynamic monitoring, an essential skill for today's intensivists. It offers a valuable guide for beginners, as well as for experienced intensivists who want to hone their skills, helping both groups detect an inadequacy of perfusion and make the right choices to achieve the main goal of hemodynamic monitoring in the critically ill, i.e., to correctly assess the cardiovascular system and its response to tissue oxygen demands. The book is divided into three parts: from physiology to pathophysiology; clinical assessment and measurements; and clinical practice achievements. All chapters use a learning-oriented style, with practical examples, key points and take home messages, helping readers quickly absorb the content and, at the same time, apply what they have learned in the clinical setting. The European Society of Intensive Care Medicine has developed the Lessons from the ICU series with the vision of providing focused and state-of-the-art overviews of central topics in Intensive Care and optimal resources for clinicians working in Intensive Care.

This book describes the pathophysiological significance of the hemodynamic monitoring parameters available to the clinician and their role in providing reliable and reproducible information on the cardiocirculatory status of a patient in shock. It is explained how measurements of these parameters enable the intensivist to understand the patient's condition and to make more informed treatment decisions in order to optimize the hemodynamic status and improve the prognosis. Full guidance is provided on measurement of intravascular blood pressures, cardiac output, and derived variables. Methods of cardiac output determination based on the classical pulmonary thermodilution, transpulmonary thermodilution, echocardiography, and Doppler techniques are reviewed. Techniques based on calibrated and non-calibrated pulse contour analysis are discussed, with attention to their limitations. Furthermore, the dynamic indices of fluid responsiveness, their clinical applications, and issues related to their use are addressed. Care is also taken to explain the physiological concepts underlying various devices used by anesthesiologists and intensivists.

Heart failure incidence increases with age and because the oldest segment of the population in Western countries is the fastest growing, the prevalence of heart failure is expected to increase. Understanding the signs and symptoms of heart failure is therefore of increasing necessity for physicians. Hemodynamic monitoring provides data on blood flow and pressure to assist physicians in determining the status of the patient's heart and in managing heart failure. This issue provides a detailed picture of the various options for assessing hemodynamics, including clinical assessment, echocardiography, transthoracic impedance cardiography, pulmonary artery catheters, B-type natriuretic peptide levels, and implantable devices.

This unique book provides clinicians and administrators with a comprehensive understanding of perioperative hemodynamic monitoring and goal directed therapy, emphasizing practical guidance for implementation at the bedside. Successful hemodynamic monitoring and goal directed therapy require a wide range of skills. This book will enable readers to: * Detail the rationale for using perioperative hemodynamic monitoring systems and for applying goal directed therapy protocols at the bedside * Understand the physiological concepts underlying perioperative goal directed therapy for hemodynamic management * Evaluate hemodynamic monitoring systems in clinical practice * Learn about new techniques for achieving goal directed therapy * Apply goal directed therapy protocols in the perioperative environment (including emergency departments, operating rooms and intensive care units) * Demonstrate clinical utility of GDT and hemodynamic optimization using case presentations. Illustrated with diagrams and case examples, this is an important resource for anesthesiologists, emergency physicians, intensivists and pneumonologists as well as nurses and administrative officers.
