[Infectious enterocolitis in intensive care patients fed by nasogastric tube].
Infectious enterocolitis sometimes spreads through intensive care units, the origin being contamination by "drips". A 9 month study concerning patients fed by nasogastric "drip" revealed 70 p. 100 of cases of severe diarrhea. Stool cultures confirmed the infectious origin of this diarrhea in 66 p. 100 cases. Virtually all of the suspect drip containers and fluids contained the organisms found in the stool culture, with a concentration of 10(6)-10(9) per ml/foodstuff. Enquiry revealed that contamination of these drips occurred above all in the kitchen at the time of preparation (poorly washed material, personnel often unaware of elementary hygiene). The great vulnérability of such intensive care patients predisposes them to infection of this type and the limit of danger for them is as low as 10(4) organisms per ml/foodstuff. Solutions concerning hygiene in preparation were tried with success (drips then containing only 50-100 organisms per ml/foodstuff.
