Brandis, Insensible Water Loss , , http: Can the development of IAH indeed be explained by sodium intake and water balance? Sergent bronzed brays his appointment without paying attention. The authors declare that there is no conflict of interests regarding the publication of this paper. In addition, populations investigated in previous publications were considerably smaller than in our study [ 20 , 26 ]. Our PDMS provided us the opportunity to incorporate all sources of sodium intake, including tube feeding and medication.
Renal cation excretion was measured in patients with IAH. Preview this year’s edition: Balance Study During the study period, 97 patients were eligible for inclusion. Data are expressed as median with interquartile range IQR or as a number with the corresponding percentage. Urine analysis was limited to spot urine samples and was restricted to patients with IAH. These samples were obtained as soon as possible after the occurrence of IAH.
In several studies, IAH was associated with higher morbidity and mortality and a prolonged length of stay in the ICU [ 457 — 9 ]. Total sodium intake after 48 hours was Length of stay of patients with IAH was significantly longer in comparison to the control group 4 [3—5] versus 6 [4—12],Table 2. Patients with IAH are characterized by low urine cation excretion, despite positive fluid balances.

Indeed, in our study on renal cation excretion, the vast majority of patients with IAH displayed a total renal cation excretion below serum sodium concentration. Our PDMS provided us the opportunity to incorporate all sources of sodium intake, including tube feeding and medication. As a by-product of an ongoing trial, spot urine samples were available in patients with IAH.
The balance study showed that development of IAH is not fully explained by differences in sodium intake or fluid balance. Therefore, prospective studies concerning handling and distribution of sodium and sodium balance, including hormone activity, to unravel the complex aetiology cxse IAH are needed.
Full studdy and sodium balances were not performed; sodium and water content in sweat and stool were left out of the equation. Our observation that IAH was related to severity of illness, independent of sodium intake and fluid balance, may be in line with an inflammation mediated pathway.

These samples were obtained as soon as possible after the occurrence of IAH. Total sodium intake and fluid balance 48 hours after admission in patients with and without developing IAH. However original data on the differences in sodium intake and fluid balance between ICU patients with and without IAH seem to be scarce. Due to diurnal variation in renal sodium excretion spot urine samples are not optimal in evaluating urine sodium excretion.

Our data do not seem to be completely in line with previous literature and with the equation as described by Edelman. It helps to explain key concepts and introduce up to date data to help my preparation Such inability to excrete cations was previously suggested by others as a contributing factor in the 2106 of IAH [ 14 — 162627 ].

Thereby, IAH does not seem to be a primary iatrogenic complication. The authors declare that there is no conflict of interests regarding the publication of this paper. ICU patients either are incapable f5885 swallowing or have limited access to free water whilst being sedated during mechanical ventilation [ 714 ]. Urine analysis was limited to spot urine samples and was restricted to patients with IAH. Although we did not measure urea excretion, the positive fluid balances in our patients make excessive renal water loss by osmotic diuresis as a cause of IAH unlikely.
Groups were classified on the assumption that in nonhypovolemic patients a total renal excretion of sodium and potassium lower than sNa implies impaired ability of the kidney to excrete cations [ 15 ]. This is in line with our own observations that consistent reduction of sodium intake, by replacement of all sodium-rich resuscitation fluids, did not seem to change the overall incidence of IAH in our own ICU department [ 6 ].
