Enteral nutrition in acute pancreatitis: a survey of practices in canadian intensive care units.
BACKGROUND
Enteral nutrition (EN) is becoming the standard of care for the artificial nutrition support of the patient with severe acute pancreatitis. This study was designed to describe nutrition support practices for acute pancreatitis in Canadian intensive care units (ICUs) and to identify any barriers to the provision of EN in this patient population.


METHODS
After an initial letter of invitation, a survey was sent to all Canadian ICUs with a census of > or = 8 beds. At each center, the critical care dietitian was asked 13 questions about usual practice of providing nutrition support to critically ill patients with acute pancreatitis.


RESULTS
Out of 62 ICUs successfully contacted through the initial letter that met entry criteria, responses were obtained from 54 (87%). EN was provided to patients with pancreatitis routinely in 13% (7/54) of units, occasionally in 72% (39/54), and never in 15% (8/54) of the ICUs. Technical difficulty obtaining small bowel access, reported by 38 units (72%), and lack of physician support for EN, as noted in 25 units (47%), were identified as the most common barriers to EN in this population. Enteral access was most commonly obtained via the nasojejunal route. The time frame from ICU admission to initiation of EN (when provided) differed widely between centers, varying from up to 24 hours to 48 hours in 22 units (48% of 46 ICUs), 3 to 5 days in 19 units (41%), and >5 days in 5 units (11%). Supplemental parenteral nutrition (PN) was commonly added to EN, routinely at 8 centers (18% of 45 ICUs) and only occasionally in another 20 units (44%). The duration of supplemental PN when used in conjunction with EN was <7 days in 83% (24/29) of the ICUs. When EN was not initiated, PN was used in all but one ICU.


CONCLUSIONS
Although EN is being commonly provided to patients with acute pancreatitis, PN use remains prominent in many ICUs across Canada. Technical difficulty obtaining small bowel access and lack of physician support seem to be the most common barriers impeding use of EN.
