Nenämahaletkujen

Nenämahaletkujen, commonly referred to as nasogastric tubes, are medical devices used to deliver nutrition, medication, or other liquids directly into the stomach via the nasal cavity. They are also employed to remove stomach contents, a process known as lavage, often in cases of poisoning or bowel obstruction. The tube is typically made of flexible plastic and is inserted through the nostril, down the esophagus, and into the stomach. The length of the tube varies depending on the intended use and the patient's anatomy.

The insertion of a nasogastric tube is a medical procedure that requires trained healthcare professionals. Before insertion, the tube is often measured to ensure it reaches the correct depth. The patient may be asked to swallow to aid in the tube's passage. Once in place, the tube's position is confirmed, usually with an X-ray, before any feeding or aspiration begins. Securement of the tube to the patient's nose is crucial to prevent dislodgement.

Nasogastric tubes are used in a variety of clinical situations. They are vital for patients who cannot eat or drink normally due to conditions such as stroke, head injury, or certain cancers. They can also be used in infants with feeding difficulties or in intensive care settings. While generally safe, potential complications include discomfort, nosebleeds, sinus infections, and, rarely, esophageal or gastric perforation. Regular monitoring and care are essential to minimize these risks and ensure the tube functions effectively.
