Additionally, there is still research being conducted on whether intubation and suctioning of meconium in newborns with MAS is beneficial, harmful or is simply a redundant and outdated treatment. In general, there is still no generally accepted therapeutic protocol and effective treatment plan for MAS.

There has been an excellent response to this treatment, as the survival rate of MAS while on ECMO is more than 94%.

As MAS describes a spectrum of disorders of newborns born through MSAF, without any congenital respiratory disorders or other underlying pathology, there are numerous hypothesised mechanisms and causes for the onset of this syndrome. Long-term consequences may arise from these disorders, for example,
