Bibliography: p. 137-154. / 154 p. : / Title page, contents and abstract only. The complete thesis in print form is available from the University Library. / This thesis details a series of studies in patients, in human volunteers and in large animals. Haemodynamics and left ventricular systolic and diastolic mechanics are reported during lactic acidosis, during therapies for lactic acidosis, and during hyperdynamic and hypovolemic shock. The study has the unifying hypothesis that cardiac dysfunction is important in hyperdynamic and hypovolemic shock and is not caused by lactic acidosis. / Thesis (M.D.)--University of Adelaide, Dept. of Anaesthesia and Intensive Care, 1997?
