Acid gastro-esophageal reflux in the 10 degrees-reversed-Trendelenburg-position in supine sleeping infants.

Many pediatricians recommend, empirically, the "supine reversed-Trendelenburg sleeping position" in infant regurgitation, although its efficacy has not been validated. Esophageal pH monitoring data from 10 consecutively investigated regurgitating infants show that the acid reflux parameters in all of them were increased in the "supine reversed-Trendelenburg position at 10 degrees" in comparison to the flat supine sleeping position. We conclude that further studies are needed to evaluate the effect of the "supine reversed-Trendelenburg position" on reflux parameters before recommending this position as a possible treatment to decrease esophageal acid exposure.
