摘要: Objective. Intravascular pressure and cardiac output monitoring are frequently performed in the operating room intensive care unit. Currently, is only measured intermittently, although continuous measurement would be preferable. One method proposed for measuring continuously arterial waveform pulse contour analysis. This study examines utility of trending using analysis during manipulations blood pressure.Methods. Eleven patients were studied while undergoing resection cerebral arteriovenous malformations. Cardiac by was compared with thermodilution measurements subjected to induced hypotension esmolol restoration phenylephrine.Results. Esmolol infusion resulted a decrease mean from 81±13 62±7 mm Hg (p<0.025), 6.4±0.9 4.4±1.1 L/min 6.2±1.0 4.5±0.9 L/min. Phenylephrine increased 68±6 95±9 no change either or output.Conclusions. demonstrates that surgery malformations brain, able reflect accurately phenylephrine.
