Successful use of a bulk laxative to control the diarrhea of tube feeding.
The greatly increased nutritional demands of the severely burned patient frequently require the use of tube feeding for enternal hyperalimentation. At a time when general patient morale is low and motivation needs to be maximally maintained, there is nothing so dispiriting as the distress of a painful perianal region and uncontrollable liquid stools. Attempts to control the diarrhea which frequently accompanies tube feeding by changing the formula or the method of administration or a wide variety of constipating drugs have all met with very limited success. Based on the clinical observation of a noted gastroenterologist (Bockus), we have administered a mucilagenous hydrophilic colloid bulk laxative (Metamucil) to patients on tube feeding formulae. The dosage and frequency are adjusted to individual patient needs, but average 7 g per liter of liquid formula. The results have been dramatic; namely, the virtual elimination of the diarrhea problem in our burn patients on enteral hyperalimentation by gastric tube feeding. Colonic transit time increases. The stools become formed but soft, cohesive but not adhesive. Perianal irritation does not occur. Neither does soilage of wound, dressings, or bed. No rebound constipation or obstructive symptoms have been encountered. We attribute this response to the same water binding mechanism that allows these colloids to prevent chronic constipation. Our patients may be given as much as 5,000 to 6,000 calories of tube feeding per day. Our patients are not distressed by diarrhea. Our nursing staff is relieved of the burden that entails.
