Brief Summary

Daily Fluid Balance vs Weight Change

Conditions

Weight Bias; Weight Change; Fluid Balance; Fluid Accumulation

Keywords

fluid balance; weight change; fluid accumulation; fluid deresuscitation

Outcome Measures

Primary Outcomes (1)

• Agreement between 24hour fluid balance and daily weight change

  The primary objective of the study is to assess the agreement between changes in body weight and cumulative 24-hour fluid balance over identical time intervals in ICU patients.

  24 hours from enrollment

Study Arms (1)

ICU patients

Adult patients admitted to a intensive care unit without any extracorporeal life organ support excluding artificial lung ventilation.

Other: Daily Weight and fluid balance change

Interventions

Daily Weight and fluid balance change OTHER

In all enrolled patients, both 24-hour body weight change and cumulative 24-hour net fluid balance will be assessed over identical 24-hour intervals by nursing personnel. Fluid balance will be recorded using a standardized 24-hour fluid balance chart and calculated as the difference between total fluid intake and urine output and fluid output to drains. Body weight measurement will be performed once daily. Body weight will be measured using the integrated weighing system of the ICU bed.
