BACKGROUND: When intubating newborns, clinicians aim to place the tip of the endotracheal tube (ETT) in the mid-trachea. Clinicians usually estimate the ETT insertion depth based on weight. ETT tips are often incorrectly positioned in newborns. Estimating the insertion depth based on gestation may be more accurate. OBJECTIVE: To determine whether estimating the ETT insertion depth using gestation, compared to weight, results in more correctly placed ETTs. METHODS:Newborn infants without congenital anomalies who were intubated orally were randomised to having their ETT insertion depth estimated using weight [insertion depth (cm) = weight (kg) + 6] or gestation [value determined from a table]. The primary outcome was correct ETT position, defined as an ETT tip between the upper border of the first thoracic vertebra (T1) and the lower border of the second thoracic vertebra (T2) on a chest X-ray. The primary outcome was determined by one paediatric radiologist who was masked to group assignment. RESULTS:Ninety infants were enrolled and the groups were well matched. The proportion of correctly placed ETTs was not significantly different between the groups [weight, 25/49 (51%), vs. gestation, 16/41 (39%), p = 0.293]. We found no significant differences in the secondary outcomes measured. CONCLUSION: Estimating the ETT insertion depth in newborns using gestation compared to weight did not result in more correctly placed ETTs.

The proportion of correctly placed ETTs was not significantly different between the groups [weight, 25/49 (51%), vs. gestation, 16/41 (39%), p = 0.293].
