Detection the relationship between preoperative ionized magnesium levels and the risk of acute kidney injury after cardiac surgery.
Acute kidney injury (AKI) is a major medical problem that is of particular concern after cardiac surgery. The reported prevalence of cardiac surgery-associated acute kidney injury (CSA-AKI) is up to 30% and is independently associated with an increase of morbidity and mortality .So this study is for measuring preoperative ionized magnesium levels of patients who will undergo cardiac surgeries then measuring postoperative serum creatinine, BUN and urine output to detect if they developed AKI or not and if there is a relationship between the post cardiac surgery AKI and preoperative ionized magnesium levels.

Detection of the relationship between cardiac surgery associated AKI and preoperative magnesium levels.
Post cardiac surgery AKI according to KDIGO criteria with low preoperative magnesium level
Measuring preoperative magnesium level and postoperative kidney functions in form of serum creatinine in umol/L , BUN in mmol/L and urine output ml/h to detect the relationship between preoperative low magnesium level and risk of acute kidney injury after cardiac surgery.
Time frame: Baseline
Post cardiac surgery AKI according to KDIGO criteria with normal or high preoperative magnesium level
Measuring preoperative magnesium level and postoperative serum creatinine, BUN and urine output to detect the relationship between preoperative magnesium level and risk of acute kidney injury after cardiac surgery.
Time frame: basline
Post cardiac surgery normal kidney functions with low preoperative magnesium level
Measuring preoperative magnesium level and postoperative serum creatinine, BUN and urine output to detect the relationship between preoperative magnesium level and risk of acute kidney injury after cardiac surgery.
Time frame: basline
