Local and Whole Organ Renal Oxygenation under Hemorrhagic Shock
Reports of various authors on the use of different techniques for assessing tissue oxygenation under a variety of hemorrhagic shock conditions abound in this symposium and in the literature (1,2). Undoubtedly these add to our knowledge of this exciting and complex clinical and experimental state. Our hope is that coordinated efforts will be undertaken to compare techniques and experimental designs and thus facilitate interpretation of results. In this way the role played by anesthesia, surgical trauma, temperature, and degree and duration of shock, among other variables, can be evaluated. In addition, changes in results due to changes in size, location, and type of electrodes as well as duration and type of polarographic voltage can be identified. This report is about one of our attempts in this direction: the comparison of local renal oxygenation changes with those of the whole kidney under hemorrhagic shock.
