Can the development of IAH indeed be explained by sodium intake and water balance? These mechanisms are derived from the Edelman equation, which in simplified form is as follows [ 17 ]:

The study on renal cation excretion revealed that most patients with IAH seem to have an impairment in renal cation excretion. On the other hand, decrease in total body water, caused by renal or extrarenal water loss, or insufficient water intake may enhance the rise in sNa. Distribution of data was evaluated by histograms and Shapiro-Wilk testing. In critically ill patients, an impaired ability to excrete cations has been reported, independently of their volume status [ 14 , 15 ]. Our data do not seem to be completely in line with previous literature and with the equation as described by Edelman. Full fluid and sodium balances were not performed; sodium and water content in sweat and stool were left out of the equation. The ICU is a bed combined medical and surgical unit in a tertiary teaching hospital.

Lastly, an important difference between this study and previous publications is the cutoff value for IAH. Activity 7 especially good – can be used for class activities, homweork or if a teacher is absent. The current paradigm does not seem to explain IAH to the full extent and warrants further studies on sodium handling in ICU patients. Or can it be explained by renal cation excretion?

Stidy, in our study on renal cation excretion, the vast majority of patients with IAH displayed a total renal cation excretion below serum sodium concentration. In healthy volunteers, water-free sodium storage has been described [ 32 ]. Storage of osmotically inactive sodium in extremely high concentrations has been reported in cartilage, muscle, bone, and skin [ 31 — 33 ].

Although we did not measure urea excretion, the positive fluid balances in our patients make excessive renal water caes by osmotic diuresis as a cause of IAH unlikely. The historical aspects are particularly useful and avoid students having to do the research themselves Data are expressed as median with interquartile range IQR or as a number with the corresponding percentage.

Central venous pressure, as an indirect parameter of volume status, did not differ between groups Tables 2 and 3 and Figure 1. Already in Padtberg mentioned this compartment [ 30 ].

Routine daily collected measurements of sNa, serum creatinine concentration, and serum urea concentration were used. It matches the OCR one well – applied directly to the pre release case.

The author has done a good job. It helps to inform my planning and also gives students the confidence that they are understanding the Sthdy material Apart from severity of illness scores, which were higher in patients developing IAH, there was no significant difference between groups at baseline. These samples were obtained as soon as possible after the occurrence of IAH. Pg 6 – deals with diffent types of deficit -good as often confused by students As a first step to unravel the aetiology of IAH, we performed two complementary observational studies to answer the following questions: Mentioned fluid balances did not include fluid administration prior to ICU admission.

Current, up to date and studg. Severity of illness was the only independent variable predicting development of IAH and low cation excretion, respectively. Full fluid and sodium balances were not performed; sodium and water content in sweat and stool were left out of the equation.

BoxRB Groningen, Netherlands.

Two retrospective studies were conducted: Subscribe to Table of Contents Alerts. I liked the additional materials particularly and the exam practice with example answers – really helpful. Patients were divided into two subgroups: In the balance study, sNa was used as a dichotomous variable to determine the difference in total sodium intake and fluid balance between groups after 24 and 48 hours.
