Hyperosmolality and Acute Kidney Injury After Cardiac Surgery

Not Applicable
Completed
Conditions
Acute Kidney Injury
Osmolality Disturbance
Cardiopulmonary Bypass
Interventions
Drug: HighOsmo
Registration Number
NCT05914896
Lead Sponsor
Umeå University
Brief Summary

The goal of this randomized controlled trial is to test if a hyperosmolar prime solution used for cardiopulmonary bypass increases the risk for acute postoperative kidney injury.

Detailed Description

Two-hundred cardiac surgical patients were randomised into two groups based on the osmolality level of the prime solution used for cardiopulmonary bypass. The high osmolality group (966 mOsm) received a prime solution containing Ringer-Acetate 1000 ml + Mannitol 400 ml (60 g) + Sodium-Chloride 40 ml (160 mmol) and Heparin 2 ml (10 000 IU), while the reference group with normal osmolality (388 mOsm) received a prime solution containing Ringer-Acetate 1400 ml and Heparin 2 ml (10 000 IU).
