Objective: To understand the process and challenges facing neonatal transport in Canada and to delineate their composition and working.Subjects and methodology: An online questionnaire was sent to all neonatal transport team directors/coordinators in Canada. The questionnaire covered different aspects of transport and was pilot tested prior to finalization. The responses were anonymous to the investigators.Results: All sixteen neonatal transport teams in Canada surveyed. Fifteen teams responded. Dedicated team as a model was adopted by 12 teams (80%). A combined Neonatal/pediatrics team, where the team could be assembled by either neonatal or pediatrics intensive care staff, adopted by two (13%). Team members were cross-trained in about quarter of the teams (four teams out of 15) with respiratory therapists and registered nurses performing each other's roles. Neonatal Resuscitation Program was mandatory for all teams that responded (15 teams) to become certified as a neonatal transport team member. Nine teams use a central dispatch phone call system.Conclusion: As the first to comprehensively describe the status of neonatal transport in Canada, our study shows that neonatal transport teams have similarities as well as differences. Regionalization and differences in referral practices, geography, provincial laws, and manpower are the main reasons why teams may have their individual variations in policies, protocols, and logistics. Our data can be utilized by health professionals and policy makers to improve neonatal transport logistics within their health care systems resulting in better outcomes of transported neonates.

The Q factor of a cavity resonator in a two-dimensional phononic crystal comprised of tungsten rods in a silicon matrix is analyzed. Incorporating loss into the model has shown that the silicon material limit on Q is achieved by using a two-dimensional phononic crystal design with a reasonable length.

Spontaneous tension pneumothorax (STP) is one of the acute emergent conditions in Neonatal Intensive Care Units (NICU) which requires immediate diagnosis and intervention. STPs are traditionally managed with invasive interventions; needling and intercostal chest tube (ICT) placement. We report a novel approach of managing STP in a term infant, with surfactant therapy. A term female just born, developed increased work of breathing, tachypnea, grunting, subcostal retractions, desaturations and increasing oxygen requirement at two hours of life. Examination revealed asymmetric chest expansion and diminished left sided breath sounds. Transillumination and urgent chest x-ray confirmed the presence of left-sided tension pneumothorax. This STP was successfully treated with needling aspiration and surfactant therapy. Baby fully recovered with these interventions and did not require chest tube drainage. We believe that surfactant therapy is worth trying and has the potential to preclude the need for an ICT and its consequences. This relatively easier treatment modality for STP deserves further trials to assess its usefulness and efficacy. [ABSTRACT FROM AUTHOR]

Introduction Brain herniation is an extremely rare complication of hypoxic ischaemic encephalopathy (HIE) in the neonatal period with only a single report described. We report a 2-day-old term infant with severe HIE, who developed diffuse brain oedema and herniation. Case presentation and description A term female infant delivered by vacuum, required therapeutic hypothermia for severe encephalopathy. At 36 hours of age, a marked change in neurological status was noted with signs of brainstem involvement. A head Computed Tomography Scan showed uncal and tonsillar herniation. Conclusion Vigilance in monitoring neonatal neurological status during therapeutic hypothermia is imperative for early brain herniation detection. [ABSTRACT FROM AUTHOR]
