“…Such knowledge is also important for anaesthesiologists, since airway management is a crucial point in their approach to patients, and tracheobronchial tree variants are to be well known (García Araque et al, 2014; Wooten et al, 2014).…”

Anatomical variability in the human body is not as rare as was previously hypothesised. Indeed, as recently reviewed, the term ‘norm’ in anatomy can be considered an approximation. Thus, anatomical variations occur quite often, as largely demonstrated during non‐invasive diagnosis, surgical intervention, or post mortem investigations. In the present study, we describe different anatomical variations in both the right and left lungs derived from cadavers of different ethnicities. The analysed organs were collected during dissection, and accessory lobes and fissures were observed in both the right and left lungs. Moreover, a horizontal fissure was missing from the right lung, resulting in only two lobes. Since lung anatomical variability is common in clinical practice and preclinical imaging studies can miss different morphologies, a deep and accurate knowledge of the anatomical variations of the lung is of extreme importance to avoid difficulties or changes during the surgical procedure.

In this work, we aim to achieve low-cost real-time tracking for nasogastric tube (NGT) insertion by using a tracking method based on two magnetic sensors. Currently, some electromagnetic (EM) tracking systems used to detect the misinsertion of the NGT are commercially available. While the EM tracking systems can be advantageous over the other conventional methods to confirm the NGT position, their high costs are a factor hindering such systems from wider acceptance in the clinical community. In our approach, a pair of magnetic sensors are used to estimate the location of a permanent magnet embedded at the tip of the NGT. As the cost of the magnet and magnetic sensors is low, the total cost of the system can be less than one-tenth of that of the EM tracking systems. The experimental results exhibited that tracking can be achieved with a root mean square error (RMSE) of 2–5 mm and indicated a great potential for use as a point-of-care test for NGT insertion, to avoid misplacement into the lung and ensure correct placement in the stomach.
