Effect of Gastric Lavage in Preventing Feeding Problems in Late Preterm and Term Neonates Born With Meconium Stained Amniotic Fluid : A Randomized Controlled Trial
Effect of Gastric Lavage in Preventing Feeding Problems in Late Preterm and Term Neonates Born With Meconium Stained Amniotic Fluid : A Randomized Controlled Trial
The purpose of the study is to evaluate the role of gastric lavage in preventing feeding problems in babies born through meconium stained amniotic fluid. It is a routine practice in many hospitals to perform gastric lavage in all babies born with meconium stained amniotic fluid after stabilisation without any supporting evidence. It is believed that meconium is an irritant and its presence in stomach causes gastritis and vomiting and hence the basis for this practice. Orogastric tube insertion and subsequent gastric lavage is not without complications. Potential complications will be prevented and health resources will be saved if this procedure is not proven to be beneficial. Therefore the investigators decided to study if gastric lavage reduces incidence of vomiting and other feeding difficulties as well as incidence of respiratory difficulties in babies born with MSAF.
Meconium passage in newborn infants is a developmentally programmed event normally occurring within first 24-48 hours of birth. The meconium staining of amniotic fluid occurs in 12% of all live births per annuum.
The routine use of gastric lavage in MSAF babies has been advocated for a long time as a part of the conventional treatment. Meconium in stomach is hypothesized to act as an irritant and cause vomiting and retching. Surprisingly this recommendation is also made in some textbooks without supporting evidence.
Orogastric tube insertion and subsequent gastric lavage can cause complications like bradycardia, apnea, vomiting, trauma, aspiration and esophageal or gastric perforations. Some researchers have found that gastric suction done at birth is associated with long term risk for functional intestinal disorder. The sequence of prefeeding behaviour is disrupted in children who undergo gastric suction and it can delay initiation of breast feeding. Small elevation in mean arterial blood pressure, increased retching have also been reported The role of gastric lavage in preventing feeding problems and secondary meconium aspiration syndrome has not been systematically evaluated. If this procedure is not proven to be beneficial it will prevent potential complications which may arise due to it in a significant number of babies. Also in a resource limited country the cost of materials required and time of medical personnel will be saved. Hence the purpose of this prospective randomized controlled trial is to compare the incidence of feeding problems and secondary meconium aspiration syndrome, in gastric lavage group vs no lavage group.
