Randomized Controlled Trial Clinical Trial
Removing meconium from infant tracheae. What works best?
At least nine mechanical devices are available for suctioning the tracheae of meconium-stained newborns. To our knowledge, the efficacy of these devices, as well as various suction pressures and patterns, has not been previously compared. We performed this investigation to assess these variables. ⋯ Among the techniques compared, the meconium aspirator at -150 mm Hg, using continuous suction, performed best in this model. It is unknown, however, to what extent the tracheal mucosa may be affected by this degree of negative pressure.
