Studies show that dying patients may spontaneously reduce their intake without experiencing hunger or thirst. This stage, called natural dehydration, offers benefits by producing a sedative effect on the brain and reducing secretions and excretions, making the dying process more tolerable.
Providing tube feedings to an actively dying person can interfere with the natural course of dehydration that causes severe discomfort. Artificial feeding tends to increase respiratory secretions that may cause aspiration. It can also cause an accumulation of fluids in the abdomen. It makes it more difficult for patients to breathe. Moreso, artificial feeding may expand the edema layer around tumors of cancer patients which contributes to worsening of pain and discomfort.
All of the above factors may be helpful in assessing the administration or placement of tube feeding to other individuals with advanced pathological conditions. The use of tube feeding must always have to be evaluated in terms of the totality of a patient’s condition considering any undesirable effects and the likelihood of benefit. We cannot just demand or refuse artificial nourishment or tube feeding without the proper understanding of it ramification. The use of artificial feedings and intravenous fluids should always be assessed, taking into account their risks and benefits on patient’s overall health and condition.
It is important that healthcare professionals explain to surrogates and family members that the patient may cease eating and drinking near the end of life. It is helpful to assure them that the staff continues to keep the patient as comfortable as possible. Family members may also participate in basic care, like applying ice chips or mouth swabs to relieve dryness and other simple comfort measures. These interventions may provide relief to family members that despite stopping tube feedings and other treatments, they continue to render care to their loved ones until the end.
