1Neonatology Unit, Paediatric Department, Institut d'Investigació Germans Trias i Pujol, Hospital Germans Trias i Pujol, Universitat Autònoma de Barcelona, Badalona, Spain; Working Group on Ultrasound of the Spanish Society of Neonatology (SENeo), Valencia, Spain.
Objective:
To reduce radiation exposure in newborns admitted due respiratory distress based on the implementation of lung ultrasound (LUS).
Design:
Quality improvement (QI), prospective, before-after, pilot study.
Setting:
Third level neonatal intensive care unit (NICU) level with 25-bed and 1800 deliveries/year.
Patients:
Inclusion criteria were neonates admitted with respiratory distress.
Interventions:
After a theoretical and practical LUS training a new protocol was approved and introduced to the unit were LUS was the first-line image. To study the effect of the intervention we compare two 6-month periods: group 1, with the previous chest X-ray (CXR)-protocol (CXR as the first diagnostic technique) vs. group 2, once LUS-protocol had been implemented.
Main Variables Of Interest:
The main QI measures were the total exposure to radiation. Secondary QI were to evaluate if the LUS protocol modified the clinical evolution as well as the frequency of complications.
Results:
122 patients were included. The number of CXR was inferior in group 2 (group 1: 2 CXR (IQR 1-3) vs. Group 2: 0 (IQR 0-1), p<0.001), as well as had lower median radiation per baby which received at least one CXR: 56 iGy (IQR 32-90) vs. 30 iGy (IQR 30-32), p<0.001. Respiratory support was similar in both groups, with lower duration of non-invasive mechanical ventilation and oxygen duration the second group (p<0.05). No differences regarding respiratory development complications, length of stay and mortality were found.
Conclusions:
The introduction of LUS protocol in unit decreases the exposure radiation in infants without side effects.

Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
