13. Hepatotórax crônico devido à ruptura do diafragma direito: um desafio anestésico em um caso raro
Resumo Justificativa: A ruptura diafragmática é uma condição incomum e ocorre em 90% no lado esquerdo. No entanto, a incidência de ruptura à direita tem vindo a aumentar junto com o aumento dos acidentes automobilísticos. A herniação do fígado pode tornar-se progressiva, causar atelectasia grave do pulmão direito, resultar num débil estado respi

15. Could infarct location predict the long-term functional outcome in childhood arterial ischemic stroke?
ABSTRACT Objective: To explore the influence of infarct location on long-term functional outcome following a first-ever arterial ischemic stroke (AIS) in non-neonate children. Method: The MRIs of 39 children with AIS (median age 5.38 years; 36% girls; mean follow-up time 5.87 years) were prospectively evaluated. Infarct location was classified as the absen

16. Experimental Validation of a Cardiac Simulator for in vitro Evaluation of Prosthetic Heart Valves
Abstract Objective: This work describes the experimental validation of a cardiac simulator for three heart rates (60, 80 and 100 beats per minute), under physiological conditions, as a suitable environment for prosthetic heart valves testing in the mitral or aortic position. Methods: In the experiment, an aortic bileaflet mechanical valve and a mitral biop

17. Pulse pressure variation and stroke volume variation under different inhaled concentrations of isoflurane, sevoflurane and desflurane in pigs undergoing hemorrhage
OBJECTIVES: Inhalant anesthesia induces dose-dependent cardiovascular depression, but whether fluid responsiveness is differentially influenced by the inhalant agent and plasma volemia remains unknown. The aim of this study was to compare the effects of isoflurane, sevoflurane and desflurane on pulse pressure variation and stroke volume variation in pigs un

18. Modelling the Hot Flow Behaviors of AZ80 Alloy by BP-ANN and the Applications in Accuracy Improvement of Computations
Hot compressions of as-cast AZ80 magnesium alloy in a wide temperature range of 523-673 K and strain rate range of 0.01-10 s–1 with a height reduction of 60% were conducted by a Gleeble-1500 thermo-mechanical test simulator. The hot flow behaviors show highly non-linear intrinsic relationships with temperature, strain and strain rate. In order to model the

19. Outcomes of carotid artery stenting at a high-volume Brazilian interventional neuroradiology center
OBJECTIVES: Carotid artery stenting is an emerging revascularization alternative to carotid endarterectomy. However, guidelines have recommended carotid artery stenting only if the rate of periprocedural stroke or death is < 6% among symptomatic patients and < 3% among asymptomatic patients. The aim of this study is to evaluate and compare clinical outcomes

20. Dehydration, hemodynamics and fluid volume optimization after induction of general anesthesia
OBJECTIVES: Fluid volume optimization guided by stroke volume measurements reduces complications of colorectal and high-risk surgeries. We studied whether dehydration or a strong hemodynamic response to general anesthesia increases the probability

21. Goal-directed fluid optimization based on stroke volume variation and cardiac index during one-lung ventilation in patients undergoing thoracoscopy lobectomy operations: a pilot study
OBJECTIVES: This pilot study was designed to utilize stroke volume variation and cardiac index to ensure fluid optimization during one-lung ventilation in patients undergoing thoracoscopic lobectomies. METHODS: Eighty patients undergoing thoracoscopic lobectomy were randomized into either a goal-directed therapy group or a control group. In the goal-directe

22. A eritropoietina protege a função sistólica de corações neonatais submetidos a isquemia e reperfusão regional : trabalho experimental / Erythropoietin protects the systolic function of neonatal hearts against ischemiareperfusion injury
Background: The effect of erythropoietin (EPOT) on neonatal hearts is not well understood. The current hypothesis is that erythropoietin has protective effects against ischemia-reperfusion when administered prior to ischemia induction. Methods: Systolic and diastolic indices, as well as the Akt and extracellular regulated kinase (ERK) signaling pathways, wer

23. Hemodynamic mechanisms of the attenuated blood pressure response to mental stress after a single bout of maximal dynamic exercise in healthy subjects
To determine the hemodynamic mechanisms responsible for the attenuated blood pressure response to mental stress after exercise, 26 healthy sedentary individuals (age 29 ± 8 years) underwent the Stroop color-word test before and 60 min after a bout of maximal dynamic exercise on a treadmill. A subgroup (N = 11) underwent a time-control experiment without exe

24. Resposta cardiovascular ao exercício em pacientes portadores de hipertensão arterial pulmonar / Cardiovascular response to exercise in patients with pulmonary arterial hypertension
The proper understanding of the cardiovascular response to exercise has a central role in the management and treatment of patients with pulmonary arterial hypertension (PAH). However, data concerning the evolution of pulmonary vascular mechanics and right ventricular adaptation to effort are scarce. The aim of this study is characterize the cardiovascular re
