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

Point of Care Ultrasound Clinical Trial

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

Status Active, not recruiting

Clinical Trial Summary

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.

Clinical Trial Description

Phase 1 would entirely base on training of all newborn care providers. The training phase of the study includes two stages:

Stage 1: It will involve training of new born care providers in detecting esophageal versus tracheal intubations using the ultrasound simulator, and then ensure they are able to accurately detect this difference using our evaluation tools.

Experts in POCUS will train neonatal health care providers at Aku.

Stage 2 : It would comprise of validation and assessment of POCUS competency. For this purpose neonatal health care providers that underwent training will perform Ultrasound of intubated babies who are hemodynamically stable in NICU, captured images and save them.

These images will be interpreted in real time by the trainee and validate by trained PI. 10% images will be sent to Sick Kids POCUS trainer for revalidation. Health care provider will validate at least 10 images correctly to be certified as successfully trained and move to Phase 2.

Phase 2. New-born at The Aga Khan Hospital who requires intubation will be assessed for ETT placement via ultrasound and simultaneously with the standard methods. The time required to assess a correct endotracheal intubation will be compared between POCUS and standard care methods that are colorimetric end- tidal carbon-dioxide (CO2) detector.

Study population and sample size:

Phase 1: The training session will be provided to health care providers who attend deliveries and exclusively involved in newborn care, which include Neonatal attending, postgraduate trainees, neonatal fellows and nursing staffs.

The POCUS will be done by Fellows, attending and Senior Staff only.

Phase 2: A Sample size of 292 newborn will be recruited considering these assumptions that in the Aga khan university, Hospital Karachi currently has approximately 5,000 deliveries per year and 600 infants per year require admission in the NICU (12% of total NICU admissions). ;
