242:. The tube is then marked at this level to ensure that the tube has been inserted far enough into the patient's stomach. Many commercially available stomach and duodenal tubes have several standard depth markings, for example 46 cm (18 in), 56 cm (22 in), 66 cm (26 in) and 76 cm (30 in) from distal end; infant feeding tubes often come with 1 cm depth markings. The end of a plastic tube is lubricated (local anesthetic, such as 2% xylocaine gel, may be used; in addition, nasal vasoconstrictor and/or anesthetic spray may be applied before the insertion) and inserted into one of the patient's anterior nares. Treatment with 2.0 mg of IV midazolam greatly reduces patient stress. The tube should be directed straight towards the back of the patient as it moves through the nasal cavity and down into the throat. When the tube enters the

Otolaryngology, is performed by a physician to pull a material through the nares and then tied with the ends shortened to prevent removal of the tube. The other method is a device called the
Applied Medical Technology, or AMT, bridle. This device uses a magnet inserted into both nares that connects at the nasal septum and then pulled through to one side and tied. This technology allows nurses to safely apply bridles. Several studies have proven the use of a nasal bridle prevents the loss of the NG placement that provides necessary nutrients or suctioning. A study conducted in the UK from 2014 through 2017, determined that 50% of feeding tubes secured with tape were lost inadvertently. The use of bridle securement decreased the percentage of NGs lost from 53% to 9%.

One method and the least invasive is tape. Tape is positioned and wrapped around the NG tube onto the patients nose to prevent dislodgement.

Function of an NG tube properly placed and used for suction is maintained by flushing. This may be done by flushing small amounts of saline and air using a syringe or by flushing larger amounts of saline or water, and air, and then assessing for the air to circulate through one lumen of the tube,
