Intraosseous and intravenous epinephrine administration during resuscitation of asphyxia
Objective: Intraosseous access is recommended as a reasonable alternative for vascular access during newborn resuscitation if umbilical access is unavailable, but there are minimal reported data in newborns. We compared intraosseous with intravenous epinephrine administration during resuscitation of severely asphyxiated lambs at birth. Methods: Near-term lambs (139 days' gestation) were instrumented antenatally for measurement of carotid and pulmonary blood flow and systemic
Sustained Inflation Versus Intermittent Positive Pressure Ventilation for Preterm Infants at Birth
Objective: To characterize respiratory function monitor (RFM) measurements of sustained inflations and intermittent positive pressure ventilation (IPPV) delivered non-invasively to infants in the Sustained Aeration of Infant Lungs (SAIL) trial and to compare vital sign measurements between treatment arms.
Study design: We analyzed RFM data from SAIL participants at five trial sites. We assessed tidal volumes, rates of airway obstruction and mask leak among infants allocated t
Assessment of optimal chest compression depth during neonatal cardiopulmonary resuscitation
Aim: The study aimed to examine the optimal anterior-posterior depth which will reduce the time to return of spontaneous circulation and improve survival during chest compressions. Asphyxiated neonatal piglets receiving chest compression resuscitated with a 40% anterior-posterior chest depth compared with 33%, 25% or 12.5% will have reduced time to return of spontaneous circulation and improved survival. Methods: Newborn piglets (n=8 per group) were anaesthetised, intubated,
Effects of varying chest compression depths on carotid blood flow and blood pressure in asphyxiated
Background: Current neonatal resuscitation guidelines recommend chest compressions (CCs) should be delivered to a depth of approximately 1/3 of the anterior-posterior (AP) chest diameter. The aim of the study was to investigate the haemodynamic effects of different CC depths in a neonatal piglet model. Methods: CCs were performed with an automated CC machine with 33%, 40% and 25% AP chest diameter in all piglets in the same order for a duration of 3 min each. Results: Eight n
Using eye-tracking augmented cognitive task analysis to explore healthcare professionals' cognition
Aim: We aimed to describe the cognitive processes of healthcare providers participating as airway leads in delivery room neonatal resuscitations using eye-tracking assisted debriefing to facilitate recall and provide situational context. Methods: Delivery room neonatal resuscitations were recorded using eye-tracking glasses worn by participants who acted as airway leads. These glasses analyze eye-movements to produce an audio-visual recording approximating what was "seen" by
In Newborn Infants a New Intubation Method May Reduce the Number of Intubation Attempts: A Randomize
Severe desaturation or bradycardia often occur during neonatal endotracheal intubation. Using continuous gas flow through the endotracheal tube might reduce the incidence of these events. We hypothesized that continuous gas flow through the endotracheal tube during nasotracheal intubation compared to standard nasotracheal intubation will reduce the number of intubation attempts in newborn infants. In a randomized controlled pilot study, neonates were either intubated with con
