Effect of Miralax NPO Time on Residual Gastric Volumes and Bowel Preparation

Effect of Miralax NPO Time on Residual Gastric Volumes and Bowel Preparation

The goal of this clinical trial is to assess differences in residual gastric volumes after stopping Miralax ingestion at different time points (2, 4, 6 hours) prior to anesthesia induction and compare it to the control (current institutional standard of care where no Miralax is given on the day of surgery).
