Plain English summary of protocol
Background and study aims
The aim of this study is to determine the effect of giving intravenous saline (0.9%) hydration before open heart surgery on kidney function after surgery and the prevention of acute kidney injury.
Who can participate?
Patients aged 18 to 85 years with normal kidney function who are undergoing cardiac surgery
What does the study involve?
Participants are randomly allocated to one of two groups. The first group (control group) will have fluid restriction for 12 hours before surgery and the second group (case group) will be hydrated with 0.9% normal saline for 12 hours before surgery.
What are the possible benefits and risks of participating?
This study aims to prevent kidney injury with a basic low-cost technique. The researchers monitor the participants to prevent hypervolemia (fluid overload) so are no risks expected.
Where is the study run from?
Kartal Koşuyolu High Specialization Training and Research Hospital (Turkey)
When is the study starting and how long is it expected to run for?
June 2020 to December 2021
Who is funding the study?
Kartal Koşuyolu High Specialization Training and Research Hospital (Turkey)

| Scientific title | The effect of preoperative hydration on cardiac surgery-associated acute kidney injury |
| Study objectives | The hypothesis of this study is that preoperative intravenous saline (0.9%) hydration can prevent postoperative cardiac surgery-associated acute kidney injury instead of the traditional dehydration protocols prior to surgery |
| Ethics approval(s) |
Approved 22/09/2020, Health Sciences University Kartal Kosuyolu High Specialization Training and Research Hospital’s Clinical Research Ethics Committee (Denizer st. Cevizli Avenue, Istanbul, 34865, Türkiye; +90 (0)2165001500; aysezehrakarakoc@gmail.com), ref: 2020/8/36122/09/2020 |
| Health condition(s) or problem(s) studied | Open-heart surgery in patients with a glomerular filtration rate (GFR) >45 ml/min/1.73 m², not undergoing dialysis, and without ventricular dysfunction |
| Intervention | G-power analysis was used to determine the total sample size and with an effect size of 0.48 (alpha error probability=0.05) and a power value of 0.80, the total required sample size was found to be 110 (at least 55 patients for each group). SPSS v.23 software package was used for data analysis. Patients scheduled for open-heart surgery between October 2020 and December 2020 at Kosuyolu Heart Hospital, with a GFR >45 ml/min/1.73 m2, not undergoing dialysis, and without ventricular dysfunction, were randomly divided into two groups. The first group was left with fluid restriction overnight before surgery, while the second group was subjected to preoperative 12-hour intravenous hydration with 0.9% saline. During this process, their total fluid intake and outputs were monitored to avoid any hypervolemia. |
| Intervention type | Other |
| Primary outcome measure(s) | BUN, creatinine, and GFR values and blood gas values (pH, lactate, HCO3, Na++, K+, etc.) measured on postoperative days 0, 1, 2, 3, and 7, and at the first month and the first year |
| Key secondary outcome measure(s) | 1. Total drainage recorded during the hospital stays of the patients 2. ICU stay recorded during the hospital stays of the patients 3. Total hospital stay recorded during the hospital stays of the patients 4. Extubation times recorded during the hospital stays of the patients |
