Event Description

It was reported that, during tula procedure, the patient was fitted with size 2 earplug in one ear, the ear was filled appropriately, and the control unit displayed an alert when the hcp attempted to initiate iontophoresis.It was determined that the hcp had attempted to start the channel that was not yet connected; when they pressed the correct channel, iontophoresis initiated appropriately.The surgeon then attempted to place the second earset using a size 2 earplug, determined that it was too small and changed to a size 3 earplug.Then, the ear was filled and iontophoresis initiated.During iontophoresis, the patient was moving significantly; both the parents and multiple hcps attempted to restrain the patient movement.The earsets were dislodged multiple times leading to alerts on the control unit.The alerts may also have been due to leaks.The patient was not able to be distracted with behavior management techniques.The case was aborted.After the patient left, the np stated that they just couldn't get the earsets/earplugs to stay in.Later that evening, the surgeon communicated that he had investigated the earsets after the procedure.He stated his opinion that the earset valve assembly was defective.He attempted to fill the earset using a setup he designed and claims that it does not fill properly with fluid escaping the valve prior to the reservoir being filled.
