This book was released on 2011 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'échocardiographie (ETT) a été validée pour le dépistage de l'hypertension pulmonaire (HTP). Sa place dans le diagnostic et le suivi de l'HTP reste toutefois mal définie. Plusieurs études récentes mettent en doute la pertinence clinique de l'estimation de la pression artérielle pulmonaire systolique (PAPs) par ETT. Objectif. Les but de l'étude sont d'analyser la corrélation entre les mesures, à l'ETT et au cathétérisme artériel pulmonaire, de PAPs et de débit cardiaque, et de définir des indices échocardiographiques de dysfonction ventriculaire droite dans l'HTP. Méthodes: Il s'agit d'une étude prospective monocentrique, dans laquelle les CAP et ETT ont été réalisés pour chaque patient dans un intervalle de moins d'une heure. Résultats: Cinquante neuf patients ont été inclus dans l'étude. Cent vingt neuf évaluations hémodynamiques ont été réalisées par CAP et ETT. Pour la mesure de la PAPs par les 2 techniques, le biais était de 4,48 mmHg et les limites d'aggrément 95% étaient de -25,11 et 34,09 mmHg, avec une corrélation de r=0,62 (p0,001). Nous avons montré une pertinence clinique satisfaisante de l'ETT pour le diagnostic d'HTP. La mesure d'une vitesse maximale du flux d'insuffisance tricuspide 2.94 m/s permet de prédire la présence d'une HTP avec une sensibilité et une spécificité de 86% et 93% respectivement (AUC=0,924). Le calcul de la PAP moyenne à partir de la PAPs ETT permet de faire le diagnostic d'HTP avec une sensibilité et une spécificité de 84% et 93% respectivement (AUC=0,925). Nous avons montré qu'une valeur de l'excursion systolique du plan de l'anneau tricuspide (TAPSE) 17 mm permet de prédire la présence d'une HTP avec une sensibilité et une spécificité de 58% et 93% respectivement (AUC=0,789) et est associé dans 86% à une dyspnée de stade III ou IV. Nous avons déterminé qu'une valeur de rapport des surfaces télédiastoliques des ventricules droit et gauche (STDVD/STDVG) 0,78 est associée au diagnostic d'HTP avec une sensibilité et une spécificité de 66% et 93% respectivement (AUC=0,828) et à une dyspnée de stade III ou IV dans 85% des cas. Nous avons montré que la mesure de la vélocité de l'onde S tricuspidienne ne permettait pas de prédire la présence d'une HTP (p=0.8 et AUC=0.53). Nous avons mis en évidence une absence de corrélation entre les mesures de débits cardiaque à l'ETT et au CAP (biais de -0,54 L/min, limites d'aggrément 95% entre 3,55 et -4,64, r=0.2, p=0,002). Nous n'avons pas retrouvé de corrélation entre l'évaluation ETT de la PAPO, à l'aide de l'analyse en Doppler pulsé du flux mitral et du Doppler tissulaire mitral, et sa mesure invasive par le CAP (r=0,04, p=0,16). Neuf patients ont bénéficié d'une réévaluation dans le cadre de leur suivi d'HTP. Nous avons montré une bonne corrélation entre les mesures de PAPs et de débit cardiaque à l'ETT et au CAP chez ces patients mais ces résultats restent à confirmer sur un effectif plus important. Conclusion: Nos résultats ont permis de confirmer l'utilité de l'ETT pour le dépistage de l'HTP. Elle permet d'étudier des paramètres de la fonction ventriculaire droite comme le TAPSE et le rapport STDVD/STDVG, prédictifs d'une HTP et associé à une dyspnée de stade III ou IV. Ces indices pourraient être utilisés dans l'algorithme de prise en charge thérapeutique de ces patients. L'utilité de l'ETT pour le suivi des patients atteints d'HTP reste à confirmer.

This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Objectif : comparer l’estimation de la quantification de la pression artérielle pulmonaire par une séquence IRM de flux 4D accélérée avec le cathétérisme cardiaque droit et avec l’échocardiographie trans-thoracique (ETT), chez des patients suspects d’hypertension pulmonaire (HTP). Matériel et méthode : 15 patients (12 hommes et 3 femmes, d’âge moyen 60,7 ans) atteints ou suspects d’HTP ont été inclus dans cette étude prospective au CHU d’Amiens. Tous les patients ont bénéficié d’un cathétérisme cardiaque droit, d’une IRM cardiaque et d’une ETT qui étaient réalisés dans un intervalle de moins de 15 jours. Les pressions artérielles pulmonaires étaient mesurées en cathétérisme et estimées en ETT. Les flux cardiaques et de l’artère pulmonaire (AP) ont été mesurés en IRM par une séquence de flux 4D accélérée par la méthode « kat-ARC » et par des séquences de flux 2D. Résultats : les modèles d’estimation des pressions artérielles pulmonaires moyenne (PAPm) et systolique (PAPs) mesurées en cathétérisme incluaient uniquement des variables mesurées en IRM de flux 4D : l’hélicité moyenne au sein du ventricule droit (VD), la vitesse maximale de l’insuffisance tricuspide (Vmax IT), le rapport des diamètres du ventricule droit/ventricule gauche (VD/VG) et l’aire de section maximale systolique de l’artère pulmonaire (Amax AP). On obtenait ainsi PAPm = [33,068 x VD/VG 4D] + (0,115 x hélicité moyenne VD) – [0,173 x Vmax IT 4D] – 2,336, avec R2 = 0,813 (p = 0,029) et PAPs = (0,074 x Amax AP 4D) + (0,184 x hélicité moyenne VD) - (0,257 x Vmax IT 4D) + 2,266, avec R2 = 0,833 (p = 0,03). La PAPs estimée en IRM était significativement corrélée à la PAPs mesurée en ETT (r= 0,82). Les Vmax de l’AP, de l’insuffisance pulmonaire (IP) et de l’IT mesurées en IRM 4D étaient significativement corrélées à l’IRM de flux 2D (r = 0,79, 0,91 et 0,7 respectivement). Conclusion : cette étude suggère que l’IRM de flux 4D est une technique non invasive prometteuse pour l’estimation des pressions artérielles pulmonaires qui apparaissaient bien corrélées aux mesures de PAPm et de PAPs en cathétérisme cardiaque droit et à la PAPs estimée en ETT. Cette séquence peu chronophage pourrait s’inscrire, à terme, dans le diagnostic et le suivi des patients atteints d’HTP.

Download or read book Hypoxic Respiratory Failure in the Newborn written by Shyamala Dakshinamurti and published by CRC Press. This book was released on 2021-10-29 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: We have all been hypoxic. Fetal tolerance for intrauterine hypoxia arises from evolutionarily conserved physiological mechanisms, the antecedents of which can be learned from diving mammals or species at high altitudes. Understanding fetal hypoxia leads to understanding the huge physiological shifts of neonatal transition and the dangers of perinatal hypoxia. This comprehensive volume of topical review articles by expert authors addresses the origins of hypoxia tolerance, the impact of oxygen on circulatory transition at birth, and the biochemistry of hypoxia in the pulmonary circuit, as well as the classification, diagnosis, and clinical management of hypoxic respiratory failure and persistent pulmonary hypertension in the term neonate. The goal of Hypoxic Respiratory Failure in the Newborn is to connect our understanding of hypoxia from animals in extreme environments, with how the human fetus handles its hypoxic environment; and why the human newborn suddenly cannot. The book will educate health care professionals on how to care for newborns with hypoxic respiratory failure, including the use of up-to-date diagnostic tools and therapies. It also highlights areas of controversy and ongoing research in hypoxic respiratory failure and pulmonary hypertension of the newborn, including challenging case studies. Key Features Explores evolutionary context and comparative physiology of hypoxia tolerance in the fetus and neonate, from basic research to clinical scenarios Provides guidance to trainees, physicians, and allied health professionals engaged in NICU care; pediatricians, cardiologists, pulmonologists, anesthesiologists, neonatologists, and physiologists to effectively manage infants in hypoxic respiratory failure Includes case scenarios emphasizing current diagnostic and therapeutic controversies and algorithmic approaches to decipher difficult clinical cases

Download or read book Ethics in Obstetrics and Gynecology written by Laurence B. McCullough and published by Oxford University Press, USA. This book was released on 1994 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a comprehensive and clinically practical approach to ethics in the everyday practice of obstetrics and gynecology. The topics the authors address include: contraception, abortion, selective termination of multifetal pregnancies, gynecologic cancer, in vitro fertilization, surrogacy, prenatal diagnosis, fetal therapy, cephalocentisis, prematurity, HIV infection, and court ordered cesarean delivery. The issues involved in making decisions in many of these areas are a source of conflict, and lead to crisis between the physician and patient. One of the book's strengths is its emphasis on prevention and, if prevention fails, management, of the conflicts and crises which arise in these areas of medicine. The authors develop their preventative and management strategies on the basis of a framework for bioethics in the clinical setting. This framework is rigorously established and defended. The authors argue that four virtues -- self effacement, self sacrifice, compassion, and integrity -- generate the physician's obligation to protect and promote the patient's interest. They then identify the three types of patient's interests -- social role interests, subjective interests, and deliberative interests -- and they reinterpret the ethical principles of beneficence and respect for autonomy in terms of these. The concept of the fetus as patient, the physician's obligation to third parties, and the moral standing of fathers and family members are also addressed. The implications of their argument sets the stage for the discussions of prevention and management in the remaining sections of the book. Ethics in Obstetrics and Gynecology is a unique addition to the literature in both biomedical ethics and obstetrics and gynecology. It demonstrates that ethics should be regarded as an essential part of obstetrics and gynecology, and that clinical practice is incomplete without i
