Problem: boston scientific do brasil ltda reported that "in an area with known excessive moisture and heat, one of our customers lost control of the environment (temperature and humidity) in the area where the hemashields were stored, resulting in the formation of" drops " of the glycerol in the inner blister of the product packaging. the drops appeared in the form of clear, liquid crystalline, water-like spheres. customers opted not to use these products by prolonging the surgery on the patient until a product without drops was located, delaying the surgical procedure in 20 - 30 minutes. " the company reported that "glycerol is one of the materials used in the collagen coverage of hemashield products, and is the source of the observed droplets. exposure of hemashield products to extreme temperature and humidity conditions has been known as a result of this consequence for some time, however, but never before, this has been reported as an impact on patient safety. while (...)
