Model Number 103
Event Date 04/07/2011
Event Type  Injury  
Event Description

It was initially reported by a physician that a pt was having laryngeal spasms, which had required her hospitalization in the past. At this time, the pt had 3 spasms and the pt turned cyanotic. The pt's vns physician turned the output current down from 2. 5 ma to 2. 0 ma, stopping the spasms. The pt was reported to be "doing better" after the change in parameters. Further info was received from the physician, which stated the spasms did correlate with the vns stimulation, but the pt "was having other issues going on, too". Consequently, it was difficult for the physician to say what was causing the effect exactly. Diagnostic results were not available from the site, there were no other factors that could have contributed to the event, and the pt did not have a history of this event prior to vns. However, the site then claimed the relationship to vns for this event was not known. The site claimed that the pt's mother was going to "see what happens" at the lowered setting and re-evaluate at a later time. A search of the mfr's programming history database revealed that last known diagnostics on (b)(6) 2011 were within normal limits.
