- Item[Bedside evaluation of hemodynamic and respiratory data with a programmable pocket calculator].(1983-04-21) Zadrobilek, E; Draxler, V; Mauritz, W; Sporn, PInformation obtained from repeated measurements of basic haemodynamic and pulmonary artery catheterization data has become useful for treatment of critically ill patients In addition the determination of cardiac output the systemic central venous pulmonary arterial and pulmonary capillary wedge pressures and blood gas data of arterial and mixed venous sampling allow to calculate derived cardiorespiratory variables Since manual computation is a time consuming measure in the daily routine of an intensive care unit and online computer monitoring an expensive one we developed a program for bedside use in a handheld programmable calculator This program incorporates the following characteristics calculation of standard hemodynamic oxygen transport and perfusion related variables temperature correction of blood gas data and derivation of oxygen saturation and intrapulmonary shunt
- Item[Monitoring kidney function in abdominal infection].(1986-02-06) Sporn, P; Mauritz, W; Redl, G; Schindler, I; Zadrobilek, EIn ICU patients suffering from abdominal sepsis acute renal failure ARF is a common 50 incidence and often lethal more than 80 mortality complication Continuous monitoring of renal function is necessary for both adequate fluid replacement and early detection of ARF Using a programmable handheld computer the following parameters are calculated at least daily creatinine osmolal and free water clearance fractional excretion of sodium and potassium and non saline loss The clearance values are corrected to 1 73 m2 body surface area Free water clearance proved to be a particularly valuable guide for fluid therapy as well as for early diagnosis of ARF In all septic patients renal function is impaired to some degree since despite increased cardiac output creatinine clearance is only normal or even decreased More than 50 of our patients with abdominal sepsis develop ARF resulting in a dramatic increase in mortality Goal of renal monitoring in sepsis is to detect ARF as early as possible and to differentiate between extrarenal and septic origin to enable immediate surgical treatment
