Introduction: Early EN is believed to benefit critically injured patients. However, it is a common perception that EN is poorly tolerated after resuscitation from hemorrhagic shock. Purpose: Report the efficacy of delivering EN using a standardized protocol in patients who survived shock resuscitation. Also, to analyze the reasons for deviation from the protocol (i.e. intolerance) in these patients. Methods: Prospective data collection of feeding tolerance, as part of an EN protocol designed and implemented by a multidisciplinary ICU team, in patients resuscitated from hemorrhagic shock. After obtaining jejunal access an immune-enhancing EN formula was started at 15 cc/hr and advanced by 15 cc/hr every 12 hrs to a goal based upon anthropometric and stress assessment. Clinical symptoms were simultaneously monitored and EN was not advanced, decreased or held based upon their severity. Results:Over a 4 month period ending July 1999, all 17 patients (age 40±4yrs, 88% blunt injury, ISS 39±4) who underwent large volume resuscitation received EN. Actual delivery of EN versus the protocol ideal is shown(table). Eight (47%) were advanced to goal without interruption. Among the remaining 9 patients there were 18 instances where EN was not advanced, decreased or stopped. The factors responsible were distention( 14/18), diarrhea (8), NGT ouput > 1000 ces (7), vomiting (1) and abdominal tenderness (1). However, despite some degree of intolerance, 88% received full dose EN by PID 7. Only 2 patients failed to reach goal and required supplemental TPN. Conclusion: EN can be successfully delivered by a standard protocol after shock resuscitation. Although symptoms of feeding intolerance are common, they are of limited duration and do not preclude effective enteral feeding.
