THE PERIOPERATIVE PERIOD AND INTENSIVE CARE MEDICINE
Lobo Antunes, Maria; D'Orey, Francisco; Ribeiro, Maria Inês; Mendes, Paula; Lança, Sara; Fernandes, AnteroHigh-risk surgery is related to the extent, invasiveness and complexity of the procedure, factors that result in an increased stress response due to surgical trauma, increased oxygen demand and increased rate of postoperative complications, which may lead to patient death. Classically, the perioperative period comprises three interrelated sequential phases: preoperative, intraoperative and postoperative. Regard...
SURGICAL RISK ASSESSMENT IS CRUCIAL TO MITIGATE POSTOPERATIVE COMPLICATIONS
Carvalho Martins, Pedro; Santos, Fátima; Sousa Menezes, Ana; Fernandes, Antero; Lara Santos, LúcioPostoperative complications often determine the failure of a meticulous and adequate surgical intervention. The surgical risk assessment allows the identification of patients who can benefit from a program to optimize their general condition, reducing the risk of postoperative complications. The purpose of this article is to address the main factors associated with increased perioperative risk as well as the mo...
Machine learning for the real-time assessment of left ventricular ejection frac...
Varudo, Rita; Gonzalez, Filipe; Leote, João; Martins, Cristina; Bacariza, Jacobo; Fernandes, Antero; Michard, FredericBackground: Machine learning algorithms have recently been developed to enable the automatic and real-time echocardiographic assessment of left ventricular ejection fraction (LVEF) and have not been evaluated in critically ill patients. Methods: Real-time LVEF was prospectively measured in 95 ICU patients with a machine learning algorithm installed on a cart-based ultrasound system. Real-time measurements taken...
Automation of sub-aortic velocity time integral measurements by transthoracic e...
Gonzalez, Filipe; Varudo, Rita; Leote, João; Martins, Cristina; Bacariza, Jacobo; Fernandes, Antero; Michard, FredericPoint-of-care ultrasound techniques are increasingly used for the bedside assessment of cardiac function and haemodynamics in critically ill patients. The sub-aortic or left ventricular outflow tract velocity time integral (VTI) can be measured using pulsed-Doppler ultrasonography from a transthoracic apical 5-chamber view. Quantifying VTI is useful to discriminate between vasoplegic states (hypotension with no...
