Children must fast for a certain period of time before anesthesia and surgery to reduce the risk of food residues being vomited up and ending up in the trachea (so-called aspiration). But there are disadvantages to fasting for a long time before an operation, for example the blood sugar level can drop and the body can become dehydrated. Small children risk such side effects to a greater degree than adults, and therefore international work is underway to revise the rules for fasting before surgery.~Enteral feeding children are a special risk group because they are usually completely dependent on tube feeding for nutrition and fluid intake.
The primary objective of the study is to compare the risk of increased stomach contents after tube feeding (Enteral feeding) 6 and 4 hours before anesthesia using antrum measured by ultrasound.
