Please summarize hata sentensi Tano, umeelewaje baada ya kugoogle?There are two scenarios to why a person involved in an accident would not be advised to be given water (oral hydration).
Three reasons which are corresponding with the person who is involved in an accident and exhibits wounds internally or externally.
1) Patient may aspirate the water if he is not fully conscious and it may cause choking and death or aspiration pneumonia as a late complication.
2) He may have suffered injuries which would need a major surgery and in such a case it is better if he hasn't taken any food or fluids.
3) A head injury may cause cerebral edema, and in the absence of any major blood loss, more fluids will aggravate the oedema and may cause irreversible brain damage or death.
And another scenario is with the person who has suffered a shock after being involved in an accident.
When a person is in shock, his or her body reduces blood flow to the digestive tract (stomach, intestines, etc.) in order to supply vital organs (heart, lungs, brain, etc.). As a result, water and food can not be absorbed normally. This often causes the person to vomit. Vomiting increases fluid loss, leaving him or her more dehydrated than before. Vomiting also raises the risk of aspiration (stomach contents getting into the trachea and lungs) which is quite dangerous.
But also during shock, the heart is unable to pump blood to meet the oxygen requirement in the tissues.
In relevant to the issue on hand is that blood is shunted to the vital organs such as the brain.
Note that the intestine is not a vital organ.
Hence, blood is shunted away via sympathetic actions that bring about vasoconstriction and reduce gut motility.
In this case if you give water or feed, the gut become prone to ischemia, gangrene and perforation because of the already compromised perfusion.
