Abstract

OBJECTIVE:

To assess a novel method, adapted from already published literature, for bedside placement of nasojejunal feeding tubes using erythromycin, air insufflation of the stomach and continuous ECG guidance.

DESIGN AND SETTING:

Prospective study in a tertiary teaching hospital.

PATIENTS AND PARTICIPANTS:

40 consecutive patients who required enteral nutrition and mechanical ventilation for at least 48 h.

INTERVENTIONS:

Erythromycin (200 mg) was administered intravenously 30 min prior to the insertion of the feeding tube. The post-pyloric feeding tube was then inserted into the stomach and 500 ml air insufflated. Stomach ECG was performed, and during further insertion of the tube the QRS complex was continuously monitored for a change in polarity, suggesting passage across the midline through the pylorus. At the end of the procedure aspirate was obtained from the feeding tube and checked for alkaline pH. Exact tube position was determined by abdominal radiography.

MEASUREMENTS AND RESULTS:

In 88% of cases the feeding tubes were post-pyloric, with a median time to insertion of 15 min (range 7-75). No major complications were seen in 52 attempts. Change in QRS polarity had 94% sensitivity in predicting post-pyloric tip placement. Of the 32 alkaline pH aspirates 31 were post-pyloric.

CONCLUSIONS:

This procedure is safe, effective and could be performed in a short time period within the confines of the intensive care unit without endoscopic assistance.
