Best Practices to Verify Ongoing Placement of NG or OG Tube After Initial X-ray Confirmation

Many patients in intensive care units (ICU) require nasogastric (NG) or orogastric (OG) tubes. These patients often require a combination of sedatives that can alter level of consciousness and impair cough or gag reflexes. Such factors can lead to NG/OG tube displacement. Using a misplaced tube can lead to aspiration, lung injury, infection, and even death.

To standardize ongoing verification of NG tube placement practices in our 34-bed Medical-Surgical ICU.

The Johns Hopkins Nursing Model was utilized to guide this project. A literature review and critical appraisal were performed to establish NG/OG tube best practices. Best practices were implemented and assessed (via a survey and charting audits).

Fifteen publications were identified and appraised as Level 4 and 5 sources. Best evidence supported that at the time of radiographic confirmation of the tube site, it should be marked with inedible ink or adhesive tape where it exits the nares; tube location should be checked at 4-hour intervals; and placement/patency should be checked in patients who complain of pain, vomiting, or coughing. Following the practice change, N = 40 nurses indicated improvement in verification of NG/OG tube knowledge, "OK to use" order was verified for 89% of patients, and 63% of tubes were marked with tape at the exit site.

Adherence to current, evidence-based strategies for NG/OG tube verification promotes patient safety. Monitoring practice changes is critical to determine whether a best practice is sustained. Electronic health records must be current to guide and support evidence-based nursing practice.
