Study Type: Interventional
Study Phase: Not Applicable

Endotracheal intubation is a life-saving intervention that few infants need after birth. Although an endotracheal tube is the most reliable way of providing positive-pressure breath, the critical factor that determines the maximal efficacy of positive-pressure ventilation is the optimal placement of the endotracheal tube tip. There are various methods available to determine the initial depth of endotracheal tube (ETT) that are based on the infant's birth weight, gestational age, anthropometric measurements, and others include vocal cord guide and suprasternal palpation methods. The Neonatal Resuscitation Program (NRP) textbook, in its 7th edition of the textbook, recommends a gestational age chart and nasal-tragus length method for estimating endotracheal tube insertion depth during cardiopulmonary resuscitation of the neonate. The evidence to support these two methods is, however, limited. Hence, we designed this study to determine the accuracy of two methods, gestational age chart and nasal-tragus length method, recommended by the Neonatal Resuscitation Program.

Time Frame
Start Date: June 15, 2020
Estimated Completion Date: December 2023
Target number of participants: 454
Experimental: Gestational Age Chart Method
In this method, the endotracheal tube insertion depth is obtained from the gestational age chart provided in the 7th edition textbook of neonatal resuscitation program (adapted from Kempley et al. PubMed identifier number: 18372092)
Active Comparator: Nasal-Tragus Length Method
In this method, the endotracheal tube insertion depth is calculated based on the formula-the distance from nasal septum tip to ear tragus+1 cm
