Objectives:
The aim of this study is to assess the usefulness of lung ultrasound (LUS) to estimate the endotracheal tube (ETT) depth position during the Intubation-Surfactant-Extubation (INSURE) procedure.
Material And Methods:
The ETT insertion depth was estimated using the weight (insertion depth (cm)=weight (kg)+5.5). After intubation two independent neonatologists using bilateral auscultation or LUS checked the ETT depth.
Results:
Twelve newborns with respiratory distress syndrome were included. In two cases LUS helped to correctly replace the ETT. All the patients progressed well, with normal x-ray and LUS before discharge.
Conclusions:
LUS appears to be a safe and non-invasive technique and is useful in clinical situations were x-ray is not routinely performed, as it is fast and radiation free.
