According to the reporter, tracheostomy was performed due to poor ventilation to the critically ill patient connected to mechanical ventilation.Premature dislodgement of the tracheostomy tube was observed after procedure, the tube was removed to be replaced but patient suffered cardiac arrest and died later on.After removing the tube, it was observed that the access to the trachea was not established, the tracheostomy tube was oriented against the right side of the trachea posterior wall, creating a false passage, resulting in loss of the airway.There was no difficulty experienced inserting the device and the tube was placed a few hours.Respirator was connected to the tube while it was in place.

Evaluation summary: no sample was returned for evaluation.Review of the two photos shows a unit pack and the remaining photo shows a used unit.Review of the photo shows that the unit is contaminated.Further examination shows that the neck plate and the tubing are not perpendicular.As no sample has been returned it is impossible to confirm if this movement happened as a result of the locking mechanism.Analysis of the retain sample confirms that the lock nut was securely locked to the neck plate and no movement was noted along the main stem of the tubing.Visual examination of the lock nut and the neck plate shows no sign of any moulding issue.The internal diameter of the neck plate and lock nut of the retain sample was measured and found to be within the blueprint specifications.In the absence of the actual complaint sample it is not possible to determine the root cause of this particular issue.All of our flange and lock nuts components are injection moulded, during this moulding process the machine setter and quality controller carry out first piece inspection.During the first piece inspection the quality controller and the machine setter verify the specifications requirements of the locknuts and flange components, measure the components and record their findings.Periodically during the lot run roving inspections are carried out.It is at these stages of the injection moulding process that any issues are identified and removed from the lot.If information is provided in the future, a supplemental report will be issued.
