About this trial

The goal of this clinical trial is to assess differences in residual gastric volumes after stopping Miralax ingestion at different time points (1-4 hours) prior to anesthesia induction.

This trial does not accept healthy volunteers

Qualifiers

Patients undergoing both EGD and colonoscopy

Use of Miralax for cleanout

Patients <19 years old

Disqualifiers

Patients with a history of delayed gastric emptying (eg diabetic, GLP-1 intake)

Patients with a history of gastric sleeve surgery

Use of Golytely for cleanout

Emergent EGD/colonoscopies

Trial outcomes

Primary outcomes

1

Residual gastric volume as measured by EGD

Time frame
To be performed at the start of the EGD immediately after anesthesia induction.

Secondary outcomes

1

Preoperative gastric POCUS volume assessment

Time frame
Performed prior to anesthesia induction
2

Effectiveness of colonoscopy cleanout

The effectiveness of colonoscopy cleanout will be assessed by the Boston Bowel Preparation Scale (BBPS).

Time frame
Performed during the colonoscopy portion following upper GI endoscopy (EGD)
3

Incidence of aspiration on induction and perioperative aspiration

Time frame
On anesthesia induction
