Additional Manufacturer Narrative
This follow-up is being submitted to relay additional information.It was reported a patient had a revision of a total knee arthroplasty.Subsequently, approximately three weeks later, required medical intervention for pneumonia and a pulmonary embolism.Procedural related complications are influenced by the "type of surgery, patients pre-existing comorbid state, and perioperative management." pneumonia is a well-known postoperative complication that typically requires medical intervention and possibly even hospitalization for more aggressive medical management.During the immediate post-operative period for a period of two hours, the protective reflexes are depressed, and the patient can aspirate.Typically, the reason for postoperative pneumonia is the aspiration of subglottic secretions containing bacteria.Once the bacteria enter the respiratory tract they can replicate if the conditions are right and advance into aspiration pneumonia.Patient that has a known history of respiratory or lung diseases i.E., copd or immune suppressed are at increased risk for developing this complication.Pneumonia is a procedural related complication resulting from intubation during the procedure.As the complaint indicates a postoperative complication of pneumonia developed, it can be implied that medical intervention was completed.Procedural related complications are influenced by the "type of surgery, patients pre-existing comorbid state, and perioperative management." if a dvt/ blood clot breaks free, it may travel through the bloodstream and block blood flow to the lungs.This complication is called a pulmonary embolism.Total joint patients are typically placed on medication post-operative for a period of time to help prevent the development of dvt/blood clot formation that can lead to an pe.As the complaint indicated the patient developed a post-operative complication, it can be implied medical intervention was completed to treat the pe.If any further information is found which would change or alter any conclusions or information, a supplemental will be filed accordingly.Zimmer biomet will continue to monitor for trends.
