Ramesh met an accident with a car and has been in `deep coma' for the last 15 days. The most suitable route for the administration of protein and calories is by : 
Select and explain. 
A. Jejunostomy tube feeding, B. Gagstrostomy tube feeding, C. Nasogastric tube feeding, D. Central venous hyperalimentation
A: Jejunostomy tube feeding
Answer: A: Jejunostomy tube feeding 
Explanation: Unless the gastrointestinal tract is non-functional, its use for nutritional support is preferable to the use of either the central or a peripheral venous route. However, in a patient who is comatose either nasogastric feeding or feedings through a gastrostomy tube may lead to vomiting and aspiration.
This problem can be avoided by using a nasoenteric tube with the tip placed in the jejunum under fluoroscopic or endoscopic control. Alternatively, a catheter may be placed directly into the proximal jejunum through a small upper abdominal incision.
