Brigitte Lemyre

Investigator, CHEO Research Institute

Dr. Brigitte Lemyre is an Associate Professor of Pediatrics and Neonatologist with the Children’s Hospital of Eastern Ontario (CHEO) and The Ottawa Hospital, where she provides care to critically ill newborns. She is also a clinical researcher with the CHEO Research Institute and Ottawa Hospital Research Institute (OHRI).

Dr. Lemyre obtained her MD degree at Sherbrooke University, in Quebec in 1993 and trained in Pediatrics and at Sherbrooke University and in Neonatal-Perinatal Medicine at McMaster University. Dr. Lemyre joined CHEO and TOH in 2001 and has been involved in many clinical trials, systematic reviews and research in the fields of neonatal ventilation and surfactant therapy, shared decision making and extreme prematurity and therapeutic hypothermia for neonatal asphyxia.  She completed in 2020 a 6 year term as a member of the Fetus and Newborn Committee of the Canadian Pediatric Society and has chaired the CHEO’s Division of Neonatology Neonatal Research Committee since 2015. She is a site investigator for the Canadian Neonatal Network and EPIQ.  Over the last 5 years, she has chaired the Extremely Low Gestational Age (ELGA)
committee in Ottawa, to improve the care provided to our smallest and most vulnerable population.

Research Projects

  1. Real-time detection of neonatal seizures improves with on demand EEG interpretation


    Combining aEEG with on-demand cEEG interpretation improved accurate seizure detection in a high-risk NICU population, with the potential to avoid over-treatment.

  2. Evaluating parental perceptions of written handbooks provided during shared decision making with parents anticipating extremely preterm birth


    Overall, parents positively evaluated the handbooks, supporting their utility for parents anticipating extremely preterm birth. Concrete suggestions for improvement were made; the handbooks will be modified accordingly. Parents at other perinatal centers may benefit from receiving such handbooks.

  3. Target oxygen saturation and development of pulmonary hypertension and increased pulmonary vascular resistance in preterm infants


    Higher targeted oxygen saturation was associated with reduced risk of PH or elevated PVR in extremely preterm infants compared to lower oxygen saturation target.

  4. Hypothermia for Newborns With Hypoxic-Ischemic Encephalopathy


    Because some studies included infants born at 35 weeks GA, hypothermia should be considered if they meet other criteria.

  5. Counselling and Management for Anticipated Extremely Preterm Birth


    Counselling couples facing the birth of an extremely preterm infant is a complex and delicate task, entailing both challenges and opportunities.
