    摘要: The invention relates to a rapid setting liquid lung sealant that forms a highly adherent and elastic hydrogel. Provided are lung sealants comprising two high molecular weight (20 kDa) multi-arm PEG compositions wherein the first PEG composition includes an alkaline buffer and the second PEG composition includes a mildly acidic buffer for optimized set up time and extended working time. In some embodiments, the PEGs further comprise a radioprotectant such as tocopherol. In some embodiments, a colorant is added to one or both PEGs of the lung sealant to improve visualization of the lung sealant against human lung tissue.
