Petersburg, Russia. We read the paper by Stawicki and Deb on the bronchial nasoenteric tube misplacement with great interest, for what we would like to extend our thanks. Despite the presence of various radiologic and endoscopic facilities, NGT—related complications are still present. The question is to recognize when, in which case, and for what signs and symptoms to use them. We would like to share another case of bronchial NGT misplacement.
Nasogastric feeding tubes xray tube misplacement to the right superior lobar bronchus. Stomach pH can be affected by the frequency of feeds. NG feeding is a common practice in all age groups. Log In. Nasogastric tubes are dray through the nares and into the stomach. You should first confirm a few key details:. Nasogastric tube NG : Nasogastric tube NG or orogastric tube OG is inserted for providing enteral nutrition, administration of drugs or for gastric drainage. Interpreting absence of respiratory distress as an indicator of Panda butts positioning.

For the ongoing confirmation of the placement of a nasogastric feeding tube, go to algorithm III. Ordinarily, small bowel aspirates are golden yellow or greenish brown intestinal fluid stained with bile ; in contrast, gastric aspirates are often grassy green, off-white, or tan.

The chest radiograph should ideally include views of the heart, lungs, trachea, mediastinum, bones of the chest and upper part of the abdomen.
- It is essential that you apply a systematic approach to your assessment and ask for senior input if you have any doubts.
- Injuries from feeding tube misplacement reported in the clinical literature include aspiration pneumonia, pneumothorax, perforations, empyema, bronchopleural fistula, and even death.
- Assessment of nasogastric NG tube positioning is a key competency of all doctors as unidentified malpositioning may have dire consequences, including death.
The chest radiograph should ideally include views of the heart, lungs, trachea, mediastinum, bones of the chest and upper part of the abdomen. Chest radiographs are done not only for diagnostic reasons to look for abnormalities in the lungs, soft tissues and bones but also to check the position of various invasive lines and tubes.
In this article, we aim to discuss and compare the normal and abnormal positions of both the endotracheal tube ETT and nasogastric tube NG on chest radiographs. Endotracheal tube ETT :. Endotracheal tubes are used to secure the patients airway. Modern ETTs have a radio-opaque line running along their length which enables us to determine their position on chest radiographs 1.
Clinical methods 2 that can be used to determine the appropriate position of the ETT include:. Symmetrical rise and fall of the chest wall with each breath on inspection and palpation of the chest. However, clinical methods cannot confirm how high or low the ETT is situated in the trachea. This can be confirmed by chest radiography. Optimum position of the ETT is required to ensure ventilation of both lungs.
A correctly positioned ETT lies in the mid trachea and its tip is approximately cm above the carina 3 as seen in Fig: 1 CR Further migration of the ETT will result in right sided endobronchial intubation and collapse of the left lung. This will result in decreased oxygen saturation values SpO 2 on a pulse oximeter and low arterial partial pressure of oxygen PaO 2 on analysis of an arterial blood gas specimen.
Nasogastric tube NG :. Nasogastric tube NG or orogastric tube OG is inserted for providing enteral nutrition, administration of drugs or for gastric drainage. NG feeding is a common practice in all age groups. In the past, various methods 4 have been used to determine the position of NG feeding tubes. Auscultation of air insufflated through the feeding tube - whoosh test. Interpreting absence of respiratory distress as an indicator of correct positioning.
Monitoring bubbling at the end of the NG tube. Observing the appearance of the feeding tube aspirate. The NPSA have issued guidance on how to confirm the position of nasogastric feeding tubes. Fig: 3 CR indicates the normal position of the NG tip below the diaphragm in the upper part of the stomach fundus.
Fig: 4 CR shows the abnormal position of the NG tube situated in the right lower lobe bronchus. If NG feeds are commenced, this will result in lung injury. Optimum positioning is required not only for safety reasons to avoid complications but also for optimum monitoring and treatment of patients. This series of chest radiographs will benefit not only medical students and doctors from all specialties but also nurses, physiotherapists and paramedical teams who will be involved in the care of critically ill patients.
On a chest radiograph, the tip of the ETT:. The ETT cannot be visualised on a chest radiograph. We wish to thank the Department of Radiology in Bedford Hospital for helping us with the chest radiographs.

Inadvertent intracranial insertion of a nasogastric tube in a non-trauma patient. Patients that are critically ill are prone to go into a catabolic state of metabolism. The tube is blocked.

Nasogastric feeding tubes xray. Methods Used to Check Correct Placement of Nasogastric (NG) Tube
Nasogastric tube position on chest x-ray (summary) | Radiology Reference Article | ardythandjennifer.com
It is essential that you apply a systematic approach to your assessment and ask for senior input if you have any doubts. Incorrect NG tube placement can result in life-threatening complications and therefore you should take great care when carrying out your assessment.
This guide aims to provide you with a systematic approach to confirming safe NG tube placement in your exams, however, it should NOT be used as a guide to confirming NG tube placement on actual patients, instead, you should follow your local hospital guidelines. As a doctor, you will inevitably be asked to check and confirm the position of a nasogastric tube before feeding commences. Complications from misplaced tubes can have serious clinical consequences, including the death of a patient, so you must take great care when assessing NG tube placement.
The oesophagus normally lies to the left of the trachea and medially to the aortic knuckle. The normal oesophagus passes through the diaphragm and enters the stomach at the gastroesophageal junction GOJ.
After an NG tube has been inserted it is common practice to attempt to obtain an aspirate which then can have its pH checked. The idea is that gastric contents normally have a low pH 1.
Aspiration can therefore potentially be used as a method for confirming safe NG tube placement without the additional need of a chest x-ray if the pH is within a safe range 0 — 5. Local guidelines, however, can differ in terms of the acceptable pH range for confirming NG tube placement and some hospitals may require chest x-rays for all patients, regardless of pH aspirate, so always consult your local guidelines.
Stomach pH can be affected by the frequency of feeds. Gaining aspirate from NG tubes can be difficult, particularly when using a fine bore tube. Access to chest x-rays is difficult in the community. You should first confirm a few key details:.
If any of the above features are not present, or you have any doubt about the placement of the NG tube you should discuss the situation with radiology who may provide an expert opinion on the imaging or arrange further contrast studies to confirm safe placement.
Correctly placed NG tube Source: Wikiradiography. This chest x-ray shows the NG tube has entered the trachea, then entered the left main bronchus and then coiled backwards over into the right main bronchus where the tip can be seen lying. Example of NG tube in right main bronchus Source: Wikiradiography. NG tube in left lung Source: Wikiradiography. This chest x-ray shows an NG tube that has been inserted into the oesophagus successfully, but has not been inserted to an adequate length.
NG tubes not placed to an adequate length can result in oesophageal reflux of feed and potentially aspiration of feed. This NG tube would need inserting further and re-assessing with an x-ray to ensure placement was adequate. NG tube not inserted to an adequate length Source: Wikiradiography. If you were unable to see the tip of an NG tube you should speak with the radiologist who may:. If asked to present your findings make sure to mention all the key criteria you have assessed to confirm the NG tube placement is safe:.
