[Changes of hemodynamics, oxygen delivery and oxygen consumption during anesthesia induction with propofol in patients with rheumatic mitral stenosis].
Changes of hemodynamics, oxygen delivery and consumption were studied in 20 patients with rheumatic mitral stenosis, undergoing mitral valve replacement, anesthesied induction with propofol(Group P) or midazolam(Group M). The results showed that hemodynamic values were decreased after intravenous propofol, and recovery after tracheal intubation. Hemodynamic values also decreased and last to 2 min after tracheal intubation in Group M. The reduction degree of HR in Group P were more, the degree of SVRI,. LVSWI, RVSWI less than those in Group M respectively. Oxygen consumption decreased more than delivery. It is suggested that induction of anesthesia with propofol in patients with rheumatic mitral stenosis is safe, and may be advantageous than midazolam.
