1/2. Management of infiltration injury in neonates using duoderm hydroactive gel.Neonates are at increased risk of injury from infiltration of intravenous fluids because of small vessel size and immature skin structure. Until recently, hyaluronidase injection was used to prevent tissue injury following the infiltration of intravenous solutions in neonates. The production of hyaluronidase injection was discontinued in 2001. The alternative, compounded hyaluronidase injection is not regulated by the U.S. food and Drug Administration and is subject to variation in quality assurance practices. Amorphous hydrogels have been used as wound dressings for sloughy or necrotic wounds in a variety of clinical settings. hydrogels facilitate autodebridement of the wound by rehydrating slough and enhancing the rate of autolysis. No adverse effects or increased infection rates have been associated with the use of hydrogel dressings. DuoDerm Hydroactive gel is a sterile, preservative-free, viscous, hydrating gel composed of natural hydrocolloids. We report our experience using DuoDerm Hydroactive gel for management of injury secondary to the infiltration of total parenteral nutrition solution and lipid emulsion in three neonates.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/2. Auditory brainstem response and temporal bone and brainstem pathology in brainstem death, with special reference to autolysis of red blood cells.We studied the pathological changes in the temporal bone and brainstem, with particular attention to the autolysis of red blood cells in and around the blood vessels, in six cases of brainstem death determined by auditory brainstem responses (ABRs). Our findings showed that the cochlea, the visceral organs and the spinal cord below a certain level of the cervical segments continued to live after brainstem death. Red blood cells in the vessels of the brainstem and cerebellum exhibited severe autolysis, whereas most red blood cells in the cochlea were preserved. Our findings of autolytic changes in red blood cells in the brainstem, and the preservation of red blood cells in the cochlea, imply initial loss of brainstem function and delayed loss of cochlear function after prolonged absence of ABRs.- - - - - - - - - - ranking = 2keywords = vessel (Clic here for more details about this article) |
