What This Study Did, in Plain Language

What Was Tested

This randomized controlled trial looks at the intervention named in the title.

The objective was to study trace element balances during continuous renal replacement therapy (CRRT) in intensive care patients.

Why It Was Studied

Acute renal failure is a serious complication in critically ill patients and frequently requires renal replacement therapy, which alters trace element and vitamin metabolism.

Who Took Part

PubMed indexes the participants as middle-aged adults and older adults, both men and women.

In a prospective randomized crossover trial, patients with acute renal failure received CRRT with either sodium bicarbonate (Bic) or sodium lactate (Lac) as a buffering agent over 2 consecutive 24-h periods.

Copper, selenium, zinc, and thiamine were measured with highly sensitive analytic methods in plasma, replacement solutions, and effluent during 8-h periods.

How the Study Was Run

The researchers set it up as a randomized and crossover study.

Random assignment meant chance, not the researchers, decided who got the intervention named in the title and who got the comparison, which limits bias.

In the crossover set-up each of the participants took both the intervention named in the title and the comparison in turn, acting as their own control.

Balances were calculated as the difference between fluids administered and effluent losses and were compared with the recommended intakes (RI) from parenteral nutrition.

What Was Measured

PubMed files the paper under topics including Acute Kidney Injury, Copper, Critical Care, Hemodiafiltration, Selenium, Thiamine and Zinc.

What This Means in Plain Language
