A Novel Training Simulator for Portable Ultrasound Identification of Incorrect Newborn Endotracheal Tube Placement, Karachi Pakistan

First seconds after birth, new born baby go through physiologic changes to successfully adjust to the external environment specially establishment of independent respiration. Majority of the organ systems adaptation in newborns occur gradually, but radical and rapid cardiopulmonary adaptation must occur for neonates to survive. It is during this period that approximately 10% neonates require some level of support in the form of resuscitation.

A knowledgeable, quick and skillful response by all caregivers is crucial for extra uterine survival. Tracheal intubation is performed frequently in the Neonatal Intensive Care Units (NICU) and delivery rooms. Neonatal intubation is a critical and time-sensitive procedure, and failure deprives the sickest newborns of oxygen.

Current methods to detect a misplaced esophageal ETT in newborns are suboptimal. Physical examination findings are often unreliable, exhaled carbon-dioxide testing is often unavailable outside of resource-rich facilities and can lead to false positive results ,while chest radiographs are not only time consuming ,labor intensive but also expose vulnerable newborn babies to significant radiation However portable ultrasound machines are relatively available even in small centers mostly being used in the maternity units, being an indispensable tool for managing obstetrics, gynecology and trauma cases.

POCUS methods of assessing ETT position offer an alternative that is time saving, cheap and safe, thereby of critical importance in the neonatal "time-is-brain" scenario.

Our project aims to demonstrate that POCUS can effectively and accurately detect esophageal intubations, and in shorter period of time than current standard-of-care methods that are colorimetric end- tidal carbon-dioxide (CO2) detector and chest x-ray.
