Overview
Meconium plug syndrome (MPS) involves obstruction of the neonatal colon by thick meconium, often presenting shortly after birth. It can be self-resolving or require intervention, with potential associations noted with Hirschsprung's disease and magnesium tocolysis 1.Diagnosis
Clinical presentation includes abdominal distension, vomiting, and failure to pass meconium within expected time frames post-birth.
Contrast barium enema is a key diagnostic and therapeutic tool, confirming the presence of a meconium plug 1.Management
First-line treatment: Observation for spontaneous resolution in approximately 30% of cases 1.
Intervention: Contrast barium enema is highly effective, with a success rate of 97% 1.
Surgical intervention: Reserved for cases with worsening symptoms leading to complications such as peritonitis 1.Special Populations
Gestational age: Lower gestational age (<36 weeks) correlates with delayed intervention timing and longer hospital stays 1.Key Recommendations
Monitor neonates with suspected MPS for spontaneous resolution; contrast barium enema should be considered if symptoms persist 1 (Evidence: Moderate).
Utilize contrast barium enema as the primary intervention for meconium plug obstruction, given its high success rate 1 (Evidence: Strong).
Early surgical consultation is advised in cases of severe complications such as peritonitis 1 (Evidence: Expert opinion).References
