Aortoesophageal fistula in a 13-yr-old girl: complication after Nasogastric tube placement in the setting of right-sided aortic arch.
Pediatric Critical Care Medicine, 2002Co-Authors: Kim L Mcbride, Eric A. Pfeifer, Mark E. WylamAbstract:OBJECTIVE: To report a case of aortoesophageal fistula in a 13-yr-old girl with a right aortic arch that occurred after Nasogastric Intubation after surgery for lumbar kyphosis. DESIGN: Case report. SETTING: Tertiary care pediatric intensive care unit. PATIENTS: One 13-yr-old girl who underwent operative repair of a 45-degree kyphosis at the level of the second to fourth lumbar vertebrae. MAIN RESULTS: On the eighth postoperative day after operative kyphosis repair and intraoperative placement of a Nasogastric tube, sudden massive hematemesis developed and the patient died. Autopsy revealed esophageal ulceration with erosions. One of these had a fistulous tract connecting to the descending aorta. The aortoesophageal fistula was observed where the descending aorta indented the posterior wall of the esophagus, as the aorta crossed the midline from the right side to the left side of the body. CONCLUSION: In the setting of right-sided aortic arch and other abnormalities of the aortic arch, Nasogastric Intubation may result in aortoesophageal fistula, massive hemorrhage, and death. Right-sided aortic arch should be added to the list of conditions for which utmost caution during Nasogastric Intubation is warranted.

A Non-invasive Real-time Localization System for Enhanced Efficacy in Nasogastric Intubation
Annals of biomedical engineering, 2015Co-Authors: Zhenglong Sun, Shaohui Foong, Luc Maréchal, U-xuan Tan, Tee Hui Teo, Asim ShabbirAbstract:Nasogastric (NG) Intubation is one of the most commonly performed clinical procedures. Real-time localization and tracking of the NG tube passage at the larynx region into the esophagus is crucial for safety, but is lacking in current practice. In this paper, we present the design, analysis and evaluation of a non-invasive real-time localization system using passive magnetic tracking techniques to improve efficacy of the clinical NG Intubation process. By embedding a small permanent magnet at the insertion tip of the NG tube, a wearable system containing embedded sensors around the neck can determine the absolute position of the NG tube inside the body in real-time to assist in insertion. In order to validate the feasibility of the proposed system in detecting erroneous tube placement, typical reference Intubation trajectories are first analyzed using anatomically correct models and localization accuracy of the system are evaluated using a precise robotic platform. It is found that the root-mean-squared tracking accuracy is within 5.3 mm for both the esophagus and trachea Intubation pathways. Experiments were also designed and performed to demonstrate that the system is capable of tracking the NG tube accurately in biological environments even in presence of stationary ferromagnetic objects (such as clinical instruments). With minimal physical modification to the NG tube and clinical process, this system allows accurate and efficient localization and confirmation of correct NG tube placement without supplemental radiographic methods which is considered the current clinical standard.

design and analysis of a compliant non invasive real time localization system for Nasogastric Intubation
International Conference on Advanced Intelligent Mechatronics, 2014Co-Authors: Zhenglong Sun, Shaohui Foong, Luc Maréchal, U-xuan Tan, Tee Hui Teo, Asim ShabbirAbstract:Nasogastric Intubation is one of the most commonly performed clinical procedures. Real-time placement confirmation of the NG tube passage at the laryngeal region into the esophagus is crucial for safety, but is lacking in current practice. In this paper, we present a compliant non-invasive real-time localization system using passive magnetic tracking method. With minimal modification to the Nasogastric tube, this system allows non-radiographic localization and confirmation of the Nasogastric tube tip; and the compliant design allows the system to ergonomically conform to the patients' necks for maximum comfort. Two compliant deformation models were analyzed to facilitate prediction of the changes in the sensor locations due to the system compliance, which allows the system parameters to be updated in real-time for accurate compensation. Simulation and experimental results demonstrate that the proposed system is capable of localizing the tube insertion, and distinguishing the NG tube placement at esophagus or trachea. A neck attachment prototype was designed and built to validate the feasibility of the proposed approach.

Nasogastric Tube Insertion for Superior Mesenteric Artery Syndrome
2016Co-Authors: A Fatal, Aortoesophageal Fistula, Of Double Aortic Arch, Tomofumi Miuraa, Junichiro Nakamuraa, Satoshi Yamadaa, Masahiko Yanagia, Yoshiko Tanib, Mamiko NishiharabAbstract:Aortoesophageal fistula · Double aortic arch · Vascular ring · Nasogastric tube · Superior mesenteric artery syndrome Double aortic arch (DAA) is a rare vascular congenital abnormality. Since a vascular ring surrounds bronchus and esophagus, any oral or nasal Intubation can physically cause fatal aortoesophageal fistula (AEF). We report herein the first case of association of DAA and superior mesenteric artery (SMA) syndrome and the second case of AEF caused by Nasogastric Intubation in an adult with DAA. A 19-year-old woman visited our hospital for nausea and vomiting. She was diagnosed with SMA syndrome by computed tomography (CT). Nasogastric Intubation relieved her symptoms in 4 days. Extramural compression with top ulceration was found in esophagogastroduodenoscopy on the 5th hospital day. She suddenly showed massive hematemesis on the 12th hospital day. AEF was found by CT. Soon, she died despite of intensive care. Retrospective interview disclosed the fact that DAA was pointed out in her childhood. We conclude that Intubation must be avoided in DAA and a detailed clinical interview about DAA is mandatory to avoid AEF
