A gastric feeding tube (G-tube or "button") is a tube inserted through a small incision in the abdomen into the stomach and is used for long-term enteral nutrition. One type is the percutaneous endoscopic gastrostomy (PEG) tube which is placed endoscopically. The position of the endoscope can be visualized on the outside of the person's abdomen ...
A gastrostomy can also be used to treat volvulus of the stomach, where the stomach twists along one of its axes. The tube (or multiple tubes) is used for gastropexy, or adhering the stomach to the abdominal wall, preventing twisting of the stomach. [2] A PEG tube can be used in providing gastric or post-surgical drainage. [6]
The size of the PEG polymer is important, with larger polymers achieving the best immune protection. PEG is a component of stable nucleic acid lipid particles (SNALPs) used to package siRNA for use in vivo. [26] [27] In blood banking, PEG is used as a potentiator to enhance detection of antigens and antibodies. [5] [28]
These tubes often have guidewires to facilitate insertion. If feeding is required for a longer period of time, other options, such as placement of a PEG tube, should be considered. [citation needed] Function of an NG tube properly placed and used for suction is maintained by flushing.

Macrogol, also called polyethylene glycol (PEG), is used as a laxative to treat constipation in children and adults. [3] It is taken by mouth . [ 3 ] Benefits usually occur within three days. [ 4 ]
Superabsorbent polymer powder. A superabsorbent polymer (SAP) (also called slush powder) is a water-absorbing hydrophilic homopolymers or copolymers [1] that can absorb and retain extremely large amounts of a liquid relative to its own mass.
The partition coefficient of PEG 400 between hexane and water is 0.000015 (log =), indicating that when PEG 400 is mixed with water and hexane, there are only 15 parts of PEG400 in the hexane layer per 1 million parts of PEG 400 in the water layer. [1] PEG 400 is soluble in water, acetone, alcohols, benzene, glycerin, glycols, and aromatic ...
