  • Title: Effects of acid base disturbance, septic shock, and calcium and phosphorous abnormalities on cardiovascular function.
    Author: Mehta PM, Kloner RA.
    Journal: Crit Care Clin; 1987 Oct; 3(4):747-58. PubMed ID: 3332222.
    Abstract:
    Systemic acidosis has a negative inotropic effect on myocardial function, which in the intact animal, is counteracted by the activation of the sympathoadrenal system. Although there are extensive animal data in this field, human studies quantifying the influence of systemic acidosis on myocardial function in various disease states is lacking. In patients with hypocalcemia, a single infusion of calcium does not sustain increased calcium levels, and the hemodynamic improvement is only transient. Hemodynamic changes in septic shock are complex, and there are convincing data documenting myocardial dysfunction in sepsis. There is a need for elucidating the biochemical characteristics of the myocardial depressant factor (or factors).
