GONZALEZ-DAMBRAUSKAS, Sebastián et al. Experimental newborn piglet model for studying and training lung ultrasound in critically ill children. Arch. Pediatr. Urug. [online]. 2017, vol.88, n.2, pp.78-84. ISSN 0004-0584.

Background: lung ultrasound in the critically ill (LUCI) has generated growing interest in the intensive care scenario. Animal models are useful tools for training professionals in its practice. We present an animal model designed for studying and training in LUCI for critically ill children. Method: a newborn piglet was anesthetized, traqueostomized, intubated and mechanically ventilated (MV) with conventional monitoring. Different levels of PEEP were applied, and pneumothorax and pleural effusion were produced by the insertion of a thoracic drainage and instillation of air and a saline solution. Lung ultrasound was performed by using a 4-8 MHz linear probe. Prior to the experiment, 12 trainees with no previous experience attended a theoretical course on basic LUCI delivered by a radiologist. Subsequently, they visualized and practiced LUCI in the animal model. Results: basic lung ultrasound sequences were obtained, where their typical signs could be seen: normal lung ventilation during standard MV, confirmation of endotracheal tube position, lung overdistension and collapse, pneumothorax and pleural effusion. All trainees found the experience was positive and could identify every sonographic sequence. Conclusions: the animal model presented in the study could allow professionals caring for critically ill children to receive training in LUCI. Likewise, it could allow the development of research in pediatric respiratory pathology.
