Which cardiopulmonary symptoms occur with the application of acrylic bone cement during hip replacement surgery? (Select 2) . Hypercarbia . Hyperemia . Hypotension . Hypoxemia . Hypotension 009N 090 DW Pp . Hypoxemia Cardiopulmonary changes associated with the application of acrylic bone cement during hip replacement surgery include hypotension secondary to cement monomer absorption, hypoxemia secondary to air embolization, and hypoxemia secondary to fat embolization. Hypotension has been attributed to absorption of methyl methacrylate monomer, embolization of air and bone marrow, lysis of red cells and marrow, and conversion of methyl methacrylate to methacrylic acid. Hypoxemia commonly occurs. Embolic events cause increased dead space, with reduced ETCO, and increased PaCO,. Which anesthetic agent should ideally be avoided in the asthmatic patient? A. Desflurane (Suprane) B. Isoflurane (Forane) C. Ketamine (Ketalar) D. Propofol (Diprivan) A.
