Dehydration with tube feeding

Metabolic complications of EN most commonly include disorders of fluid and electrolyte homeostasis and hyperglycemia. More severely ill patients require more frequent monitoring than those who are more stable (see Table 98-9). Both dehydration and fluid overload can occur with tube feeding. Careful monitoring of fluid inputs and outputs as well as body weight is important. Dehydration may be due either to excessive fluid... 

With low catalyst activity, the thermal cracking route (pyrolysis) may also take over in the reformer tube [389]. This is the situation in case of severe sulphur poisoning or in attempts to use non-metal catalysts with low activity. The risk of carbon formation depends on the type of hydrocarbon with the contents of aromatics being critical. Ethylene formed by pyrolysis results in rapid carbon formation on nickel (refer to Section 5. 2). Ethylene may also be formed by oxidative coupling if air or oxygen is added to the feed - or by dehydration of ethanol.
