To follow-up on my pulmonary artery disaster, the patient died at 11 das post-op of respiratory failure. Probably a combination of marginal pulmonary function with one lung and SIRS. I have spoken with US Surgical and they think the handle we load the cartridges in was too old and worn. It has been here as long as I have which is over ten years. They are replacing it. The failure rate of the 30V (white) staples is less than 1%, and they have had reports of non-release. I guess we have to pay more attention to the non-disposable instruments than I thought was necessary.
