Abstract

PURPOSE: To evaluate the usefulness of sonography-guided Gastrografin enema for the diagnosis and treatment of meconium plug syndrome in premature newborns in a neonatal intensive care unit (NICU).
MATERIALS AND METHODS
Fifteen premature newborns underwent 23 sonography-guided Gastrografin enemas on the 8th day of life on average (range: 3 days-21 days). The gestational age and birth weight (mean+/-standard deviation) of the patients were 29+/-2 weeks and 999+/-148 g, respectively. The diagnosis of meconium plug syndrome was based on relevant clinical and radiological findings. Diluted Gastrografin (1:3, 17-45 ml) was administered through a rectal tube under the guidance of sonography until it reached to the cecum. Thereafter, immediate post-procedure and delayed portable abdominal radiographs were taken. All the procedures were done within the NICU. We reviewed the dates of meconium evacuation and the first feeding after the last enema from the clinical data. Radiologically, the timing of the radiographic improvement after the last enema was checked. In cases of distended distal ileum with meconium on pre-enema sonography, follow-up sonography was performed to determine the interval change after gastrografin enema.
RESULTS
None of the sonography-guided Gastrografin enemas performed within the NICU caused procedure-related complications. Meconium was evacuated within one day in all patients. In 14 patients, on average, feeding was started on the 7th day and radiographic improvement was observed on the 3rd day. Four of the five patients showing a distended distal ileum with meconium revealed a decrease in ileal distension on follow-up sonography. On the other hand, the other patient, who did not show such a decrease on follow-up sonography, was found to have ileal stenosis during subsequent surgery.
CONCLUSION
Sonography-guided Gastrografin enema is a safe and effective bedside procedure, when performed in the NICU for the diagnosis and treatment of meconium plug syndrome.
