DR GUILHERME SANT’ANNA is an Associate Professor in the Department of Pediatrics at McGill University and a staff Neonatologist at the Montreal Children’s Hospital - McGill University Health Center (MUHC). He received his MD from Brazil and completed his clinical and research training at McGill University. Dr. Sant’Anna obtained his PhD in Physiology in 2002. After that, he worked as an Associated Professor at McMaster University from 2005 to 2009 when he finally returned to McGill to purse a clinical research career. His research interests are in Neonatal Physiology (respiratory and thermoregulation) and invasive and non-invasive ventilation. He is actually investigating the role of heart rate and respiratory variability in the prediction of extubation failure in extreme preterm infants and differences in cardiorespiratory patterns immediately after extubation while babies are on nasal CPAP, non-invasive ventilation or high flow nasal cannula therapy. He is also involved in research with infants that suffered from hypoxicischemic events and have evidence of encephalopathy. His major interests in this field are infants with mild Hypoxic-Ischemic Encephalopathy (HIE). He has also developed several research collaborations at national and international levels.
