These authors found that lower hemoglobin concentrations were associated with higher hemodynamic instability and renal failure, while Nelson et al. found that a postoperative hematocrit less than 28 was associated with significant myocardial ischemia and a higher number of cardiac events.
Estos autores hallaron que las concentraciones menores de hemoglobina se asociaban a mayor inestabilidad hemodinámica y falla renal; mientras, Nelson et al. encuentran que un hematocrito postoperatorio menor de 28 se asoció a isquemia miocárdica significativa y a presentación de un mayor número de eventos cardiacos.
