Chest radiogram is done to confirm the correct position of the NGT. We report a case where radiography could not be confirmatory for the correct position of the tube in a specific group of patients.展开更多

In this study a needle with 6 degrees of freedom force/torque sensor is used to find the relationship between the pathway＇s length and the force. Our experiments show that the method with repeated extraction-insertion cy- cles can make the needle approach the target as much as possible. Meanwhile a method to obtain the appropriaterepeated extraction-insertion cycles is given to drive the needle to execute the repeat- ed cycles efficiently. Experiments and discussions were conducted to preliminarily validate the meth- od.展开更多

Although considered safe and it being a common procedure nasogastric tube misplacement can lead to serious and life-threatening complications. We present three cases of nasogastric tube misplacement in tracheostomized patients. One of the cases presented suffered from pneumothorax. Different time intervals between procedures in these different cases resulted in similar results. We would like to emphasize the importance of due conformation of correct placement of the nasogastric tube in the tracheostomy patient as well as to suggest that over inflation of the balloon securing the tracheostomy apparatus in place during nasogastric tube placement, might prevent misplacement. Nasogastric tube placement in tracheostomized patients has potential for serious complications. As such maintaining safe practice procedure is essential. Considering over inflation of the tracheostomy apparatus balloon might be beneficial as well, by preventing entry of NGT into the trachea.展开更多
